Staffing refers to the managerial function of employing and developing human resources for carrying out the various managerial and non-managerial activities in an organisation. This involves determining the manpower requirement, and the methods of recruiting, selecting, training and developing the people for various positions created in the organisation.

 

Staffing function is an integral part of human resource management and, in its wider sense, also includes the activities of determining the remuneration of workers, appraising their performance, and deciding on their promotion, transfers, etc.

 

The process of staffing starts with ascertaining the required number of various categories of employees for the organisation. This is known as manpower planning. It decides the kinds of staff and the number of staff required for the organisation. This is done through several methods like job analysis, workload analysis, etc. The next thing to be done in the staffing process is the recruitment exercise, i.e., finding out the available manpower from internal and external sources. The next step is to select the right person from the available manpower through tests and interviews and make appointments. This is followed by their placement on the jobs and necessary introduction of the work environment and the rules of compensation, promotion, transfer etc. Thus, the various steps involved in the process of staffing are as follows.

 

• Manpower Planning: Manpower planning refers to the process of estimating the manpower requirement of an organisation. While estimating the manpower requirement, the management generally keeps in mind the available infrastructure including the technology, production schedule, market fluctuation, demand forecasts, government’s policies and so on. It tentatively decides the kinds of staff as well as the number of staff needed for the organisation. The focus of the manpower planning is to get right number of qualified people at the right time.

 

• Job Analysis:. It is a pre-requisite for any recruitment exercise. The job analysis helps in determining the qualifications, skills and experience required for various categories of employees. It involves:

(i)Job Description: Identification of each job in terms of duties and responsibilities.

 

(ii) Job Specification: Determining the abilities and skills that are required for performing the job.

These two aspects of job analysis (job description and job specification) are useful in recruitment and selection of employees so as to find the right person for the job.

 

• Recruitment: The process of finding and attracting suitable applicants for employment for various activities of the organisation using the internal as well as the external sources.

 

• Internal Sources: In any business, existing employees expect that they will have chances of promotion and will be considered for higher positions before outsiders are considered. Managers therefore may promote and transfer some of the existing employees to fill the vacant positions. The advantage of internal recruitment is that it is easier for managers to fill vacancies as they are conversant with the abilities and skills of their subordinates and have records of their performances. Employees also feel happy as their work performance is recognised by management through promotion. However, there is one major drawback of recruitment through internal sources i.e., the organisation is deprived of the benefit of inducting fresh blood into its system.

 

• External Sources: All vacancies cannot be filled up from within the organisation. Existing employees may lack the required skill, initiative and qualification needed for the jobs involved. Hence managers have to recruit some persons from outside the organisation. Not only that the external recruitment provides a wide choice from among a large number of external candidates from which employees may be recruited. The workers and office employees at the lower level are often recruited from outside the organisation. The various external sources of recruitment are as follows:

 

(a)Media Advertisements: You must have seen advertisements in newspapers about vacancies in organisations. The advertisement contains details about the job, its nature, the qualification required to do the job, how to apply, etc.This is a very popular medium of advertising. The job advertisements are also given in magazines, specialised employment magazines like Employment News, RozgarSamachar, etc. Now-a-days we also commonly find such advertisements in various electronic media like television and Internet. Such advertisements normally get a very good response from the prospective candidates.

 

(b)Employment Exchanges: In India, employment exchanges have been setup by the government for bringing together job-seekers and employers who are looking for employees. Those who are in search of employment get themselves registered with the local Employment Exchanges which keep a record of all such persons in detail who require help in finding jobs. The employer informs about the vacancies to the nearest Employment Exchange. The Employment Exchange, in turn, identifies the names of the qualified employment seekers already registered with it, and forwards them to the employer for consideration. Thus, if you are seeking a job after passing the senior secondary examination, it would be better if you get yourself registered with an Employment Exchange. It may forward your name to the prospective employers keeping in view the suitability of the job as per your qualifications.

 

(c)Educational Institutions: Now-a-days, companies/big organisations maintain a close liaison with the universities, vocational institutes and management institute for recruitment of their staff. As and when the need arises, the companies send one or more of their senior executives to the institutions of repute imparting such professional/technical education to students. These executives take the interview of the interested candidates and select the suitable candidates as per their requirement. This process is popularly known as campus interview and is found to be an effective source of recruitment of managers, engineers, technicians etc. for many companies on a regular basis.

 

(d)Unsolicited Application : Those looking for jobs often apply on their own initiative. They assume that certain vacancies are likely to arise, and apply without references to any job advertisement. Managers keep record ofsuch applications and contact the suitable candidates when they need them.

 

(e)Recruitment at the Factory gate : This is found mainly in case of factory workers to be recruited on daily wages. Such workers gather in the morning at the factory gate to serve as casual workers. Very often existing regular employees go on leave, and their vacancies are filled up by recruitment at the factory gate. These casual workers having served in the factory for sometime may be considered for regular employment at some stage.

 

(f)Referrals: Quite often the management gets references about interested workers from different sources like workers unions, previous employees, existing employees, clients of the organisation etc. These sources are important because their recommendations are made by people who are associated with the organisation and are fully conversant with its requirements. Sometimes we also receive recommendations from our friends and relatives to employ persons known to them. But one should be very much cautious while considering such recommendations.

 

(g)Private Employment Agencies: In urban areas, a number of private organisations have started functioning as employment agencies. These agencies register with them the names of the individuals who are seeking employment and try to arrange job interviews for such candidates. Companies often getting touch with such agencies to provide them the details of suitable candidates for various jobs.

 

 

• Selection: Selection refers to the process of choosing the most suitable person from among the list of interested candidates. It involves going through the qualification and experience of all candidates and matching them with the expectation for the job so as to decide on the most suitable ones for the job. The entire process goes through a number of steps which may be called as selection procedure. Selection Procedures stated above, the selection procedure consists of a number of steps in logical order to identify the candidates who are to be finally appointed. These steps are :

 

• Screening the Applications: After receiving the applications from the candidates through recruitment process, the same must be examined to decide which ones deserve to be considered and followed up. Screening is usually done by a senior officer of the company or by a screening committee. The purpose of screening is to prepare a list of eligible candidates who are to be evaluated further. Candidates not eligible are thereby excluded from further consideration

 

• Holding Tests: After screening the applications, eligible candidates are asked to appear for selection tests. These tests are made to discover and measure the skill and abilities of the candidates in terms of the requirements of the job. The nature of test depends upon the nature of the job involved

 

• Selection Interview: Interview is the most important part of the selection procedure. It serves as a means of checking the information given in the application form and making an overall assessment of the candidate’s suitability for the job.

In an interview, the candidate has a face-to-face interaction with the employer or representatives of the employer, where they try to judge the ability of the candidates. They also get an opportunity to go into the details of the candidate’s background which helps a lot in assessing the candidate’s suitability.

 

• Checking of References: In addition to the requisite educational qualification, skill and experience, it is expected that the candidates who are to be considered for employment must have other qualities like balanced temperament, honesty, loyalty, etc. These qualities cannot be judged on the basis of any test. Therefore, information is obtained and verified from the heads of educational institutions where the candidates have studied, or from the persons whose names are given by the candidates as referee, or from their previous employers.

 

• Medical Examination: Candidates finally selected for the job are asked to undergo medical examination to see whether the selected candidates are physically fit for the job. A proper medical examination ensures higher standard of health of the employees and their physical fitness which, in turn, reduces the labour turnover, absenteeism and accidents.

 

• Issue of Appointment Letter: Candidates finally selected are offered to join the organisation for which a formal appointment letter is issued containing the nature of job, the remuneration, pay scale, and other terms and conditions relating to employment. Usually a reasonable time is given to the candidates to join the organisation.

 

 

 

 

 

• Induction: Induction is the process of introducing new employees to the organisation. The new employees should know under whom and with whom he/she is to work, get acquainted and adjusted to the work environment, get a general idea about the rules and regulations, working conditions etc. Usually the immediate supervisor of the new employee introduces him to his work environment. A proper induction programme is likely to reduce his anxiety on how to cope with the work and how to become part of the organisation and helps in development of a favourable attitude towards the organisation and the job.

 

• Training and Development: the employees to improve their knowledge and skill so as to be able to perform their tasks more efficiently is known as training. It is an organised activity for increasing the knowledge and skills of people for a specific purpose. The term ‘development ‘refers to the process of not only building up the skill and abilities for specific purpose but also the overall competence of employees to undertake more difficult and challenging tasks. It is generally used with reference to the training of managers and executives. Training and Development Training is an act of increasing the knowledge and technical skills of an employee for doing a particular job efficiently.

 

Development refers to the learning opportunities designed to help employees to grow. It involves growth an individual in all areas. Development help workforce to improve technical skills, problem solving skills and decision making skills. Training is necessary for new employees as well as the existing employees for improving their performance at work. For new employees, training is necessary to help them get acquainted with the method of operation and skill requirement of the job. For existing employees, training at periodical intervals is helpful for learning better ways of doing the work, and also as and when they have to undertake new jobs. Thus, training helps employees to improve their knowledge and skill and make them perform their tasks more efficiently. It also helps them in promotion and improves their attitudes and confidence levels.

 

Importance of Training and Development Benefits of training for organisations:

 

Methods of Training There are different methods of giving training to the employees which can be divided into two broad categories.

 

On-the-Job methods and Off-the-Job methods.

 

1. On-the-Job methods : In these methods, the employees learn about their jobs while doing the work duly assisted by their supervisors or seniors. These methods encourage self-learning through practice. Job instruction or coaching, and job rotation, learning while working as an assistant to a senior, understudy positions, temporary promotions are some of the common methods of on-the-job training.

 

2. Off-the-Job methods: These methods involve training employees away from the work place so that experts may conduct the training and employees are free from immediate pressure of completing the jobs at hand. Lectures with demonstration, conferences, case discussions, video shows and films are some of the common methods used as off-the-job training methods. Then, there is another off the job method of training called vestibule training. The vestibule training refers to the training in specially designed workshops in which an attempt is made to duplicate as closely as possible the actual conditions of the work place. In such workshops a large number of employees can be trained in a relatively short period of time.

 

 

• Performance Appraisal: Performance appraisal means judging the performance of employees. Specifically, it means judging the relative abilities of employees at work in a systematic manner. This enables managers to identify employees who are performing the assigned work satisfactorily, and those who are not able to do so, and why. To be fair, performance appraisal needs to be carried out using the same methods and keeping in view uniform standards of work. Generally it is the responsibility of supervisors to carry outperformance appraisal of their subordinates, and report it to their own superiors.

 

The standard of performance or the expected level of performance of an employee on a job forms the basis of judging how well the employee has performed, and whether one employee is more efficient than the other in doing a similar job. The yardstick placed may be the desired quantity of output, the quality of work done, minimisation of wastage of materials caused in the process of work etc. The choice depends upon the type of job involved. However, where quantity or number of units produced or wastage of materials form the basis of appraisal, it is likely to be more accurate. On the other hand, quality of work done may be difficult to measure and hence performance appraisal may not be very accurate.

 

 

 

 

 

 

 

 

Some Important things in staffing

 

What is Probation Period?

 

In most of the organisations the candidates are not initially appointed on permanent basis because it is considered better to try them for a few months on the job itself. This period of service is known as the period of probation. It is necessary because no procedure of selection can fully establish the qualities of a selected candidate. It is only by observing a person at work that one can find out how he performs and also how he behaves with his superior and fellow employees. If during the probation period, his performances not found satisfactory, his period of probation may be extended. The management may also transfer him to some other job at which he may be expected to do better.

 

What is Difference between recruitment and selection:-

 

Recruitment and selection are the two essential components of the staffing process. While the recruitment helps in attracting suitable candidates, selection helps in finding out the candidates who meet the requirements of the job. These are closely inter-connected activities. However, recruitment and selection differ in certain respects. While the recruitment refers to the process of attracting good applicants for jobs, selection identifies the most suitable amongst the applicants. In the recruitment process, the effort is to attract the candidates as many as possible and it is regarded as a positive process. But, selection is a negative process as it involves rejection of many candidates. Recruitment involves decisions as regard to the sources of potential candidates. Selection is made through different steps in the procedure adopted. Recruitment helps the manager to attract good candidates

Wetlands are lands transitional between terrestrial and aquatic system where the water table is usually near the water surface and land is covered by shallow water.

Essential as: control floods, water treatment, recharging of water sources, reduce sediments, check soil erosion, bulwark against encroachment by the sea, winter resort for birds and important for flora and fauna. They also provide a variety of resources

Ramsar Convention: mangroves, corals, estuaries, bays, creeks, flood plains, sea grasses, lakes etc included

A programme on conservation of wetlands was initiated in 1987 with the basic objective of identification of wetlands of national importance, assessment of wetland resources, promotion of R&D activities and formulation and implementation of management action plans

A steering committee in each state headed by the Chief Secretary consists of members from all departments related to the wetland conservation in the state. Successful model.

India is a member of the Standing Committee of the Ramsar Convention on Wetlands, 1971

Steps forward

Make use of the traditional knowledge of the people living near the wetlands for its conservation along with the engineering solutions

Monitor the impact of implementation of management action plans

Sustainable Development

• Bruntland Report (1983) was the first publication and recognition of the term ‘Sustainable Development’
  • “meeting the needs of the present generation without compromising the needs of the future generation”
• Three pillarsof sustainable development (Bruntland)
  • Care and respect for People, Planet and Prosperity (Commercial Activities) <hence poverty alleviation, conservation and business development>
  • These three pillars are of equal importance
• SD is about avalue system. It is not a scientific formula.
• Thinking beyond pure self-gratification to awareness that harm to one will eventually be harm to all.
• Interconnectednessand interdependence of all things
• All three pillars have equal importance. Focus on only one of them will unbalance the whole
• SD is a necessity, not a luxury that we can afford to miss.

Questioning Development <too detailed; at times peripheral. Be choosy>

• Current practices must change
• Should shatter the ‘development’ myth. Simply economic growth will not create more jobs and more wealth for all.
• Steady-state economics. Economic growth is measured in terms of how much we produce and consume, and what we destroy in the process need not be included in the calculations.
• 20% of the world consumes 80% of its resources
• According to UNDP, consumption of goods and services in 1997 was twice that in 1975 and six times more than in 1950.
• An estimated 1 billion people still do not have the means to meet their basic needs.
• Inequalities are increasing. The assets of world’s three richest men are greater than the combined national product of 48 poorest countries.
• Higher crime rates are associated with wider income gaps
• Jobless growth.
• Under-nutrition is still a huge problem among children

Economic Growth and Sustainability

• Over-consumption has led to depletion of resources
• Main environmental threats
  • Depletion of resources
  • Global warming
  • Expansion of waste arising from production and consumption
  • Population pressure
  • Pollution
  • Loss of biodiversity and extinction of species.
• Green National Income Account
  • Conventional national income accounting does not capture the environmental degradation due to production and consumption
  • This omission leads to misrepresentation of improvements in social welfare
  • Since there is no market for many environmental resources, it is difficult to place monetary values on them
  • Index of Sustainable Economic Welfare: adjusts the national income to make an allowance for defensive spending (i.e. that incurred in cleaning up for pollution and other forms of environmental damage)
• Economic Sustainability
  • Calls for reforms in the manner that we conduct our economic activity
  • Removing unfair trade barriers and subsidies that harm the environment
  • Upholding the polluter pays principle
  • Tax not on labour but on consumption <already there in the form of indirect taxes>
  • Pricing products in terms of value they have deducted from the common natural base
  • Increase resource productivity
• Sustainable agriculture
  • Use of practices and methods to maintain/enhance the economic viability of agricultural production, natural resource base, and other ecosystems which are influenced by agricultural activities
  • Minimizing the adverse impact on the natural resources base
  • Flexible farming systems to manage the risks associated with climate and markets

Ecological Sustainability

• Sustainable forest management
  • ‘Forest Principle’ adopted at the 1992 Rio Summit
  • In 2007, GA adopted the Non Legally Binding Instrument on All Types of Forests. The instrument is the first of its kind and is committed to promote SFM by bringing all stakeholders together
  • Ministerial Conference on Protection of Forests in Europe defined SFM as the attainment of balance between society’s increasing demands for forest products and benefits, and the preservation of forest health and diversity.
  • Forest managers must assess and integrate a wide array of sometimes conflicting factors to produce sound forest plans
  • Ecosystems approachhas been adopted by the CBD. The CBD definition of Ecosystems Approach is known as the Malawi Principles.
  • Ecosystems Approach is a strategy of management of land, water and living resources in a way that promotes conservation and sustainable use in an equitable way. Focused on use of scientific methodologies for each level of biological organisation and their interaction.
  • SFM was recognised by the parties to CBD in 2004 to be a concrete means of applying the Ecosystems Approach to forest ecosystems
• Objectives of SFM
  • Maintain environmental stability through preservation of ecological balance that has been adversely affected due to the depletion of forest cover
  • Preserve the natural heritage of the country
  • Improve productivity of forests
  • Protecting through cooperation with local communities on the principle of Joint Forest Management
• India
  • One of the 12 mega biodiversity countries of the world
  • National Forest Policy 1988emphasizes environmental stability and maintenance of ecological balance
  • Existing infrastructure for forest protection is inadequate
  • Surveys not carried out in many areas. Question of tribal rights
  • Protect from forest fires
• Integrated Forest Protection Scheme
  • 10^thFYP. In all States and UTs
  • Formed by merger of two 9^thFYP schemes: ‘Forest Fire Control and Management’ and ‘Bridging of Infrastructure Gaps in the Forestry Sector in the North Eastern Region and Sikkim’
  • Components
    • Infrastructure development: survey and demarcation, strengthening the infrastructure for Forest Protection Division
    • Forest fire control and management
  • Implementing agencies
    • Central Component: Forest Protection Division, MoEF; Forest Survey of India, Dehradun; Central institutions like Indian Council of Forestry Research and Education (Dehradun), IIFM (Bhopal) etc shall be involved
    • State Component: Forest dept of the concerned state/UT

Social Sustainability

• Fairness in the access to and benefits from the Earth’s resources
• Impact of poverty on environment/Environment and poverty are related issues
• Diverting resources to non-productive areas
• Health and SD
  • Environment and public health are inter-related
• Agenda 21was adopted at the UN Conference on Environment and Development (UNCED) [Earth Summit] in 1992
  • It also places particular emphasis on the need to take health considerations into account in planning for SD
• Urbanisation
• Need for holistic approach

Water and SD

• Agriculture consumes nearly 70 pc of water consumption worldwide, industry -22 pc and household activities – 8 pc [WDR, 2010]
• Geographical distribution of water: just nine countries account for 60 pc of all available freshwater supplies
• Industrial use takes about 60 pc of water in rich countries and 10 pc in the rest.
• Suggestions
  • Use of sea water
  • Judicial use of freshwater
  • Development of salt-resistant crops

SD in a globalising world

• Globalisation is increasing the gap between the rich and the poor
• It has to be steered so that it serves not only the commercial interests but social needs of development
• Mechanisms to safeguard trade and livelihoods, especially in developing countries, must be evolved and negotiated to make globalisation an effective vehicle of SD
• Industrialised countries must continue to assist the developing countries as well as promote trade
• Environment and social causes must not be used selectively to erect trade barriers against developing countries

 

 

• An increase in the average temperature of Earth’s near surface air and oceans since the mid-20^thcentury

• Since the industrial revolution, the burning of fossil fuels has increased the levels of Co2 in the atmosphere from 280 ppm to 390 ppm.

IPCC

• 1988 by World Meteorological Organisation and UNEP
• tasked with reviewing and assessing the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change
• Nobel Prize in 2007
• The IPCC does not carry out its own original research, nor does it do the work of monitoring climate or related phenomena itself.
• A main activity of the IPCC is publishing special reports on topics relevant to the implementation of the (UNFCCC)
• Till now, it has released four assessment reports (1990, 1995, 2001, 2007)
• Fifth assessment report is due in 2014

Tarawa Climate Change Conference

• In the lead up to COP16, the leaders of the world’s most climate-change vulnerable countries met in Kiribati in November 2010
• Ambo Declarationwas adopted
  • It calls for more and immediate action to be undertaken to address the causes and adverse impacts of climate change.

CoP-16/CMP-6, Cancun

COP-16 President: Patricia Espinosa, Mexico’s foreign secretary

COP-17 will be held in Durban

Issues

• Forestry issues and reducing emissions from deforestation and forest degradation (REDD) plus
• The developed countries are pushing for transparency from countries where they will fund climate change mitigation.
  • The assessment of carbon emission mitigation for developing countries is right now through domestic communication but is subject to international consultation and analysis. This push for transparency is a major contentious issue.
• Fast-track finance: $ 30 bn had been committed at CoP-15. A large part of this funding is yet to come through.

 

Goals

Agreements Reached

• The outcome of the summit was an agreement, not a binding treaty, which calls on rich countries to reduce their greenhouse gas emissions as pledged in the Copenhagen Accord, and for developing countries to plan to reduce their emissions, to limit global warming to less than 2 degrees celsius above pre-industrial levels.
• There should be no gap between the first commitment period of the Kyoto Protocol, which expires in December 2012, and the second phase.
• The agreement calls on the developed countries to “raise the level of ambition of the emission reductions to be achieved by them individually or jointly, with a view to reducing their aggregate level of emission of green house gases”
• Allows flexibility in choosing the base year for setting emission reduction targets
• Emissions trading and the project based mechanism under the KP shall continue to be available to Annex 1 parties as a means to meet their quantified emission limitation and reduction objectives.
• The agreements recognize that in all climate change related action,human rights must be respected. They also recognise the need to engage with a broad range of stakeholders, including youth and persons with disability, and call for gender equality and effective participation of women and indigenous people in effective action on all aspects of climate change.
• The BASIC group softened the three demands it had before the talks began
  • Necessity of a second commitment period to the Kyoto Protocol
  • Need to accelerate disbursement under the fast start finance in the form of new and additional resources through a multilaterally supervised mechanism
  • Continued dialogue on IPRs as part of the technology development and transfer issues.
• REDDis a part of the package and proposed mitigation actions include conservation and enhancement of forest carbon stocks and sustainable management of forests.
  • REDD is a set of steps designed to use market/financial incentives in order to reduce the emissions of greenhouse gases from deforestation and forest degradation. Its original objective is to reduce GHGs but it can deliver ‘co-benefits’ such as biodiversity conservation and poverty alleviation
  • REDD+ calls for activities with serious implication directed towards the local communities, indigenous people and forests which relate to reducing emission from deforestation and forest degradation. It goes beyond deforestation and forest degradation and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks
• ACancun Adaptation Framework has been proposed to strengthen and address implementation of action, and various kinds of assessments, apart from R&D and host of other issues.
• Green Climate FundThe fund will be designed by a transitional committee, with 15 members from the developed countries and 25 from the developing nations.
• Pledge by the developed countries to provide $100 bn annually till 2020.

 

Conclusion

• UNFCCC secretary-generalChristian Figueres emphasised that the main achievement of the Cancun meet has been to restore some degree of faith in the multilateral process.
• The agreements don’t mention any reduction targets.
• Though the agreements recognize the need to reduce the GHG emissions and curb the increase in global average temperatures below 2 degrees Celsius above pre-industrial levels, in the absence of any firm target, this could be an inadequate and vague provision
• Bolivia has rejected the agreement, saying that it won’t support agreement without binding emission cuts.
• In a sense, the summit was both a major step forward as well as a failure
• It was a step forward because in recent years climate change negotiations had stumbled and this meeting helped overcome that
• It was a failure because it failed to reach an agreement for binding restrictions that are required to avert global warming.
• There was no agreement on how to extend the Kyoto Protocol, or how the $100 billion a year for the Green Climate Fund will be raised or whether developing countries should have binding emissions reductions.

Convention on Biodiversity

• Opened for signature at the Earth Summit in 1992 and entered into force on December 29, 1993
• There are 193 parties. Its secretariat is based in Montreal, Canada.
• US has signed but not ratified the treaty.
• It is an internationallegally-binding treaty with three main goals:
  • conservationof biodiversity
  • sustainable useof biodiversity
  • fair and equitable sharingof the benefits arising from the use of genetic resources
• Its overall objective is to encourage actions which will lead to sustainable future
• CBD covers biodiversityat all levels: ecosystems, species and genetic resources
• It also covers biotechnology through theCartagena Protocol on Biosafety
• Its governing body is the Conference of Parties (COP). They meet every two years
• TheEcosystem Approach, an integrated strategy for the management of resources, is the framework for action under the Convention
• Precautionary principle: it states that where there is threat of significant reduction or loss of biological diversity, lack of full scientific certainty should not be used as a reason for postponing measures to avoid or minimize such threat.
• 2010 is the International Year of Biodiversity.

COP-10 of CBD

• Held at Nagoya, Japan in October 2010.
• It achieved three inter-linked goals
  • Adoption of a new ten year strategic plan to save biodiversity
  • Resource mobilization strategy to increase official development assistance for biodiversity
  • A new international protocol on access to and sharing the benefits from the use of the genetic resources of the planet (Nagoya Protocol)
• Japan Biodiversity Fund was established
• COP-11 will take place in 2012 in India

Nagoya Protocol

• Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from Their Utilization
• The protocol creates a framework that balances access to genetic resources on the basis ofprior informed consent and mutually agreed terms with a fair and equitable sharing
• Expected to enter into force in 2012
• The Strategic Plan of CBD, which aims to arrest biodiversity loss throughout the world by 2020, will be called the Aichi Target. <Aichi is the prefecture in which Nagoya is situated>

Aichi Target

• The Strategic Plan of the CBD or the ‘Aichi Target’ adopted by the meeting include 20 headline targets, organised under five strategic goals that address the underlying causes of biodiversity loss, reduce the pressures on biodiversity, safeguard biodiversity at all levels, enhance the benefits provided by biodiversity, and provide for capacity building.
• The Aichi target will be the overarching framework on biodiversity not only for the biodiversity-related conventions, but for the entire UN system.
• Some targets
  • 17 pc inland and 10 pc marine ecosystem
  • Conserving coral reefs
  • Restore 15 pc of degraded areas
  • Halve or bring to zero the rate of loss of natural habitats including forests
• Target is that by 2020, at least 17 pc of terrestrial and inland water, and 10 pc of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem are conserved
• The conservation is to be done through effectively and equitably managed, ecologically representative and well connected systemsof protected areas and other effective area-based conservation measures, and integrated into the wider landscapes and seascapes.

 

Kyoto Protocol

The Kyoto Protocol has put in place three flexibility mechanisms to reduce emission of Green House Gases. Although the Protocol places maximum responsibility of reducing emissions on the developed countries by committing them to specific emission targets, the three mechanisms are based on the premise that reduction of emissions in any part of the globe will have the same desired effect on the atmosphere, and also that some developed countries might find it easier and more cost effective to support emissions reductions in other developed or dev

developing countries rather than at home. These mechanisms thus provide flexibility to the Annexure I countries, helping them to meet their emission reduction obligations. Let us take a look at what these mechanisms are.

What are the three flexibility mechanisms put in place of the Kyoto Protocol for reducing GHG emission?

• The three mechanisms are joint implementation. Emissions Trading and Clean Development

What is Joint Implementation?

• Through the Joint Implementation, any Annex I country can invest in emission reduction projects (referred to as joint Implementation Project) in any other Annex I country as an alternative to reducing emissions domestically.
• Two early examples are change from a wet to a dry process at a Ukraine cement works, reducing energy consumption by 53 percent by 2008-2012; and rehabilitation of a Bulgarian hydropower project, with a 267,000 ton reduction of C02 equivalent during 2008-2012.

What is Clean Development Mechanism?

• The Clean Development Mechanism (CDM) allows-‘l developed country with an emission reduction or emission-limitation commitment under the Kyoto Protocol to implement an emission reduction project in developing countries as an alternative to more expensive emission reductions in their own countries. In exchange for the amount of reduction In emission thus achieved, the investing gets carbon credits which it can offset against its Kyoto targets. The developing country gains a Step towards sustainable development.
• To get a CDM project registered and implemented, the investing country’ has to first take approval from the designated national authority in the host country, establish “Additionally”, define baselines and get the project validated by a third party agency, called a Designated Operational Entity (DOE).The Executive Body of CDM registers the project and issues credits, called Certified Emission Reductions (CERs), or carbon credits, where each unit is equivalent to the reduction of one metric tonne of. C02 or its equivalent. There are more than 4200 CDM projects in the pipeline as on 14.3.2010. The expected CERs till the end of2012 is 2,900,000,000

What is “Additionality” in a CDM project ?

• The feature of “additionality” is a crucial element of a CDM project it means that the industrialized country that is seeking to establish the CDM project in the developing country and earns carbon credits from it has to establish that the planned carbon reductions would not have occurred on its own, in the absence of the CDM project. They have to establish a baseline of the project. Which is the emission level that would have been there in the absence of the project. The difference between this baseline level and the (lower) emission level achieved as a result of the project is the carbon credit due to the investing country

What are some of the concerns regarding CDM ?

• The risk of “false Credits” is a cause for concern with regard to CDM projects. If a project does not actually offer an additionally and the reduction in emission would have happened anyway Even without the project.

CoP15 (Copenhagen Summit)

• Main aim was to establish a global climate agreement for the period from 2012 when the first commitment period under the Kyoto Protocol expires
• The conference did not achieve any binding agreement for long term action
• A ‘political accord’ was negotiated by approximately 25 parties
  • Collective commitment by developed countries for new and additional resources , including forestry and investments through international institutions to a tune of $30 bn for the period 2010-12.
• Copenhagen Accord
  • Not legally binding and does not commit countries to agree to a binding successor to the Kyoto Protocol
  • Annex 1 parties would commit to economy-wide emissions targets for 2020 to be submitted by 31 Jan 2010. Delivery of reductions and finance by developed countries will be measured , reported and verified (MRV) in accordance with COP guidelines
  • Non-annex 1 countries would implement Nationally Appropriate Mitigation Actions to slow their carbon emissions
  • Commits $30 bn for 2010-12
  • Copenhagen Green Climate Fund
  • The accord shall be assessed in 2015

Reducing Emissions from Deforestation and Forest Degradation (REDD)

 

Reducing Emissions from Deforestation and Forest Degradation (REDD) is a set of steps designed to use market/financial incentives in order to reduce the emissions of greenhouse gases from deforestation and forest degradation. Its original objective is to reduce green house gases but it can deliver “co-benefits” such as biodiversity conservation and poverty alleviation.

REDD+ is being criticised by indigenous people and activists because it is designed to give more control over indigenous people’s forests to state forest departments, miners, companies etc resulting in violation of rights, loss of livelihoods etc.

REDD is presented as an “offset” scheme of the carbon markets and thus, will produce carbon credits. Forest degradation accounts for 15% of greenhouse gas emissions, about the same as transportation sector. Mitigation cannot be achieved without the inclusion of forests in an international regime. Hence, it is expected to play a crucial role in a future successor agreement to Kyoto Protocol.

E — WASTE

E-waste is not hazardous if it is stocked in safe storage or recycled by scientific methods or transported from one place to the other in parts or in totality in the formal sector. The e-waste can be considered hazardous if recycled by primitive methods

Survey was carried out by the Central Pollution Control Board (CPCB) during 2005

In India, among top ten cities; Mumbai ranks first in generating e-waste followed by Delhi, Bangalore, Chennai, Kolkata, Ahmadabad, Hyderabad, Pune, Surat and Nagpur.

 

SOLID WASTE

the discarded (abandoned or considered waste-like) materials

does not include solid or dissolved materials in domestic sewage, or

solid or dissolved materials in irrigation return flows or industrial discharges0

Conventional plastics have been associated with reproductive problems in both humans and wildlife.

Dioxin (highly carcinogenic and toxic) by-product of the manufacturing process is one of the chemicals believed to be passed on through breast milk to the nursing infant.

Burning of plastics, especially PVC releases this dioxin and also furan into the  atmosphere.

Pyrolysis-It is a process of combustion in absence of oxygen or the material burnt under controlled atmosphere of oxygen. It is an alternative to incineration. The gas and liquid thus obtained can be used as fuels.

 

Waste Minimization Circles (WMC)

helps Small and Medium Industrial Clusters in waste minimization in their industrial plants.  assisted by the World Bank with the Ministry of Environment and Forests acting   as the nodal ministry.  being implemented with the assistance of National   Productivity Council (NPC), New Delhi.

aims to realise the objectives of the Policy Statement for Abatement of Pollution (1992), which states that the government should educate citizens about environmental risks, the economic and health dangers of resource degradation and the real economic cost of natural resources.

BIOREMEDIATION

the use of microorganisms (bacteria and fungi) to degrade the environmental contaminants into less toxic forms.

Phytoremediation

is use of plants to remove contaminants from soil and water .

Rhizofiltration

• a water remediation technique that involves the uptake of contaminants by plant roots.
• used to reduce contamination in natural wetlands and estuary areas.

 

ENVIRONMENTAL IMPACT ASSESSMENT

Notification on Environmental Impact Assessment (EIA) of developmental

projects 1994 under the provisions of Environment (Protection) Act, 1986 making EIA  mandatory for 29 categories of developmental projects. One more item was added to the list in January, 2000. environmental impact assessment statutory for 30 activities

Environment Impact Assessment Notification of 2006 has categorized the developmental projects  in two categories, i.e., Category A and Category B

Ministry of Environment & Forests

‘Category A’ projects are appraised at national level by expert appraisal committee

India has constituted the State Level Environment Impact Assessment Authority (SEIAA) and State Level Expert Appraisal Committee (SEAC)  to decentralize the environmental clearance process

The objective of EIA is to foresee and address potential environmental problems/  concerns at an early stage of project planning and design.

 

 

The EIA notification establishes four stages for obtaining Environmental Clearance.

1. Screening
2. Scoping and consideration of alternatives Baseline data collection
3. Impact prediction
4. Assessment of alternatives, delineation of mitigation measures and environmental impact statement
5. Public hearing
6. Environment Management Plan Decision making
7. Monitoring the clearance conditions

Screening- It is only for Categories B

Screening Criteria are based upon:

• Scales of investment; •       Type of development; and, •      Location of development

B1 Categories project require Environmental Impact Assessment while B2 category projects are exempted from EIA.

State Level Expert Appraisal Committee determine about project categories

Climate Change

 

• It is the long term change in the statistical distribution of weather patterns over periods of time
• Though it has been happening naturally for millions of years, in recent years it has accelerated due to anthropogenic causes and has been causing global warming.
• UNFCCC defines climate change as – “a change of climate which is attributed directly or indirectly to human activitythat alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods”

 

Climate Change Mitigation

• Alternative Energy sources
  • Renewable energy
  • Nuclear Power
  • Reduce the carbon intensity of fossil fuels
• Energy efficiency and conservation
  • Transport and urban planning
  • Building design
  • Reforestation and avoid deforestation
  • Eliminating waste methane
• Geoengineering
  • Greenhouse gas remediation
    • Biomass
    • Carbon air capture
    • Carbon capture and storage
  • Societal control
    • Population
    • Sustainable life-style

 

 

defined as ‘an addition or excessive addition of certain materials to the physical environment (water, air and lands), making it less fit or unfit for life’.

Pollutants are the materials or factors, which cause adverse effect on the natural quality of any component of the environment.

Classifications

1. According to the form in which they persist after release into the environment.

• Primary pollutants: These persist in the form in which they are added to the environment e.g. DDT, plastic.
• Secondary Pollutants: These are formed by interaction among the primary pollutants. For example, peroxyacetyl nitrate (PAN) is formed by the interaction of nitrogen oxides and hydrocarbons.

2. According to their existence in nature.

• Quantitative Pollutants: These occur in nature and become pollutant when their concentration reaches beyond a threshold level. E.g. carbon dioxide, nitrogen oxide.
• Qualitative Pollutants: These do not occur in nature and are man-made. E.g. fungicides, herbicides, DDT etc.

3. According to their nature of disposal.

• Biodegradable Pollutants: Waste products, which are degraded by microbial action. E.g. sewage.
• Non-biodegradable Pollutants: Pollutants, which are not decomposed by microbial action. E.g. plastics, glass, DDT, salts of heavy metals, radioactive substances etc

4. According to origin

• Natural
• Anthropogenic

 

AIR POLLUTION

aggravated because of four developments:

Increasing traffic, growing cities, rapid economic development, and industrialization

contamination of air by the discharge of harmful substances

 

Major air pollutants and their sources

1. Carbon monoxide (CO)

• It is a colourless, odourless gas that is produced by the incomplete burning of carbon – based fuels including petrol, diesel, and wood.
• It is also produced from the combustion of natural and synthetic products such as cigarettes.
• It lowers the amount of oxygen that enters our blood. It can slow our reflexes and make us confused and sleepy.

2. Carbon dioxide (CO2)

principle greenhouse gas

3. Chloroflorocarbons (CFC)

• gases that are released mainly fromair-conditioning systems and refrigeration.
• When released into the air, CFCs rise to the stratosphere, where they come in contact with few other gases, which lead to a reduction of the ozone layer that protects the earth from the harmful ultraviolet rays of the sun.

 

4. Lead

present in petrol, diesel, lead batteries, paints, hair dye products, etc.

affects children in particular. cause nervous system damage and digestive problems and, in some cases, cause cancer.

 

5. Ozone

• occurs naturally in the upper layers of the atmosphere.
• at-the ground level, it is a pollutant with highly toxic effects.
• Vehicles and industries are the major source of ground-level ozone emissions.
• Ozone makes our eyes itch, burn, and water. It lowers our resistance to cold and pneumonia.

 

6. Nitrogen oxide (Nox)

• causes smog and acid rain. It is produced from burning fuels including petrol, diesel, and coal.
• Nitrogen oxide can make children susceptible to respiratory diseases in winters.

 

7. Suspended particulate matter (SPM)

• consists of solids in the air in the form of smoke, dust, and vapour that can remain suspended for extended periods
• The finer of these particles when breathed in can lodge in our lungs and cause lung damage and respiratory problems.

 

8. Sulphur dioxide (S02)

• a gas produced from burning coal, mainly in thermal power plants.
• Some industrial processes, such as production of paper and smelting of metals, produce sulphur dioxide.
• a major contributor to smog and acid rain.
• Sulphur dioxide can lead to lung diseases

 

9. Smog

• a combination of the words fog and smoke. Smog is a condition of fog that had soot or smoke in it.
• interaction of sunlight with certain chemicals in the atmosphere.
• primary components of photochemical smog is ozone.
• Ozone is formed through a complex reaction involving hydrocarbons, nitrogen oxides, and sunlight. It is formed when pollutants released from gasoline, diesel- powered vehicles and oil-based solvents react with heat and sunlight from biofuels, the four most serious pollutants are particulates, carbon monoxide, polycyclic organic matter, and formaldehyde

 

Pollutants

1. i) Volatile organic compounds

The main indoor sources are perfumes, hair sprays, furniture polish, glues, air

fresheners, moth repellents, wood preservatives, and other products.

 

1. ii) Biological pollutants

It includes pollen from plants, mite, and hair from pets, fungi, parasites, and some bacteria.

iii) Formaldehyde

Mainly from carpets, particle boards, and insulation foam. It causes irritation to the eyes and nose and allergies.

1. iv) Radon

It is a gas that is emitted naturally by the soil. Due to modern houses having poor ventilation, it is confined inside the house and causes lung cancers.

 

Fly Ash

Ash is produced whenever combustion of solid material takes place.

Composition

1. Aluminium silicate (in.large amounts)
2. silicon dioxide (Si02) and
3. Calcium oxide (Ca0).

Fly ash particles are oxide rich and consist of silica, alumina, oxides of iron, calcium, and magnesium and toxic heavy metals like lead, arsenic, cobalt, and coppers

 

Policy measures of MoEF:

• The Ministry of Environment and Forests vide its notification in 2009, has made it mandatory to use Fly Ash based products in all construction projects, road embankment works and low lying land filling works within 100 kms radius of Thermal Power Station.
• To use Fly Ash in mine filling activities within 50 kms radius of Thermal Power Stations.
• Arresters: These are used to separate particulate matters from contaminated air.
• Scrubbers: These are used to clean air for both dusts and gases by passing it through a dry or wet packing material.

Government Initiatives

(1) National Air Quality Monitoring Programme

In India, the Central Pollution Control Board (CPCB) has been executing a nationwide programme of ambient air quality monitoring known as National Air Quality Monitoring

Programme (NAMP).

The National Air Quality Monitoring Programme (NAMP) is undertaken in India

(i) to determine status and trends of ambient air quality;

(ii) to ascertain the compliance of NAAQS;

(iii) to identify non-attainment cities;

(iv) to understand the natural process of cleaning in the atmosphere; and

(v) to undertake preventive and corrective measures.

Annual average concentration of SOx levels are within the prescribed National Ambient

Air Quality Standards (NAAQS).

National Ambient Air Quality Standards (NAAQS) were notified in the year 1982, duly revised in 1994 based on health criteria and land uses .

The NAAQS have been revisited and revised in November 2009 for 12 pollutants, which include. sulphur dioxide (S02), nitrogen dioxide (NO2), particulate matter having size less than 10 micron

(PM10),particulate matter having size less than 2.5micron (PM2.5), ozone, lead, carbon monoxide (CO), arsenic, nickel, benzene, ammonia, and. Benzopyrene.

WATER POLLUTION

Addition of certain substances to the water such as organic, inorganic,

biological, radiological, heat, which degrades the quality of water so that it

becomes unfit for use.

Putrescibility is the process of decomposition of organic matter present in water by microorganisms using oxygen.

Water having DO (dissolved oxygen)  content below 8.0 mg/L may be

considered as contaminated.  Water having DO content below. 4.0 mg/L is

considered to be highly polluted.

Water pollution by organic wastes is measured in terms of Biochemical Oxygen Demand-(BOD). BOD is the amount of dissolved oxygen needed by bacteria in decomposing the organic wastes present in water.

Chemical oxygen demand (COD) is a slightly better mode used to measure pollution load in water. It is the measure of oxygen equivalent of the requirement of oxidation of total organic matter (i.e. biodegradable and non- biodegradable) present in water.

A cripling deformity called Minamata disease due to consumption of fish captured from mercury contaminated Minamata Bay.

Water contaminated with cadmium can cause itai itai disease also called ouch-ouch disease (a painful disease of bones and joints) and cancer of lungs and liver.

The compounds of lead cause anaemia, headache, loss of muscle power and bluish line around the gum

Excess nitrate in drinking water reacts with hemoglobin to form non -functional met haemoglobin, and impairs oxygen transport.  This condition  is  called methaemoglobinemia or blue baby syndrome.

Over exploitation of ground water may lead to leaching of arsenic from soil and rock sources and contaminate ground water.  Chronic exposure to arsenic causes black foot disease. It also causes diarrhoea,-peripheral neuritis, hyperkerotosis and also   lung and skin cancer.

SOIL POLLUTION

Industrial waste includes chemicals such as mercury, lead, copper, zinc, cadmium, cynides, thiocynates, chromates, acids, alkalies, organic substances etc

Four R’s: Refuse, Reduce, Reuse, and Recycle

NOISE POLLUTION

Sound is measured in decibels (dB). An increase of about 10 dB is approximately double the increase in loudness.

A person’s hearing can be damaged if exposed to noise levels over 75 dB over a prolonged period of time.

The World Health Organization recommends that the sound level indoors should be less than 30 dB.

Ambient Noise Level Monitoring –   Noise Pollution (Control and Regulation) Rules, 2000 define ambient noise levels for various areas as follows-

1. Industrial Area—75DB to 70Db (Day time-6am to 10pm and night time 10pm to 6am ..75 is day time and 70 is night time)
2. Commercial Area–65 to 55
3. Residential Area–55 to 45
4. Silence Zone– 50  to 40

• The Government of India on Mar 2011 launched a Real time Ambient Noise Monitoring Network.
• Under this network, in phase- I, five Remote Noise Monitoring Terminals each have been installed in different noise zones in seven metros (Delhi, Hyderabad, Kolkata, Mumbai, Bangalore, Chennai and Lucknow).

In Phase II another 35 monitoring stations will be installed in the same seven cities.

Phase III will cover installing 90 stations in 18 other cities.

Phase-III cities are Kanpur, Pune, Surat, Ahmedabad,  Nagpur, Jaipur,  Indore,

Bhopal, Ludhiana, Guwahati, Dehradun, Thiruvananthpuram, Bhubaneswar,

Patna, Gandhinagar, Ranchi, Amritsar and Raipur.

Silence Zone is an area comprising not less than 100 metres around hospitals, educational institutions, courts, religious places or any other t area declared as such by a competent authority.

 

 

RADIO ACTIVE POLLUTION

Non-ionising radiations affect only those components which absorb them and have low penetrability.   They include short-wave radiations such as ultraviolet rays, which forms a part of solar radiation. Sunburns is due to these radiation Ionising radiations have high penetration power & cause breakage of macro molecules

They include X-rays, cosmic rays and atomic radiations -(radiations emitted by radioactive elements

Alpha particles, can be blocked by a piece of paper and human skin.

Beta particles can penetrate through skin, while can be blocked by some pieces of glass and metal.

Gamma rays can penetrate easily to human skin and damage cells on its way through, reaching far, and can only be blocked by a very thick, strong, massive piece of concrete radium-224, uranium-238, thorium-232, potassium-40, carbon-14, etc.

The nuclear arms use uranium-235 and plutonium-239 for fission and hydrogen or lithium as fusion material

The radio nuclides with long half-time are the chief source of environmental radioactive pollution.

 

• located where river meets the sea.
• the most productive water bodies in the world
• The complete salinity range from 0-35 ppt is seen from the head (river end) to the mouth (sea end) of an estuary
• Coastal lakes which have their connection with the sea through small openings are better known as lagoons or backwaters acting as a natural water filter

 

Estuary Formation:

grouped into four geomorphic categories based on the physical processes responsible for their formation:

1) rising sea level; (2) movement of sand and sandbars; (3) glacial processes; and (4) tectonic processes.

India Estuarine Ecosystem

The Country has 14 major, 44 medium and 162 minor rivers drains into the sea through various estuaries.

Major estuaries occur in the Bay of Bengal.

Most of the India’s major estuaries occur on the east coast. In contrast, the estuaries on the west coast are smaller.

 

MANGROVES

are the characteristic littoral plant formation of tropical and subtropical sheltered coastlines.

are trees and bushes growing below the high water level of spring tides which exhibits remarkable capacity for salt water tolerance.

basically evergreen land plants growing on sheltered shores, typically on tidal flats, deltas, estuaries, bays, creeks and the barrier islands. require high solar radiation and have the ability to absorb fresh water from saline/ brackish water. produces pneumatophores (blind roots) to overcome respiration problem in the anaerobic soil conditions

• Leaves are thick and contain salt secreting glands.
• exhibit viviparity mode of reproduction. i.e. SeedS germinate in the tree itself (before falling to the ground). This is an adaptative medianiSintoovercome the problem of germination in Saline water.
• crystals of salt on the back of the leaves; others block absorption of salt at their roots

The mangroves of Sundarbans are the largest single block of tidal holophytic mangroves of the world. famous for the Royal Bengal Tiger and crocodiles.

The mangroves of Bhitarkanika (Orissa), which is the second largest in the Indian sub continent, harbour high concentration of typical mangrove species and high genetic diversity have (additional) special roots such as prop roots, pneumatophores  which help to impede water flow and thereby enhance the deposition of sediment in areas (where it is already occurring), stabilize the coastal shores, provide breeding ground for fishes. protects coastal lands from tsunami, hurricanes:and floods release oxygen back to the atmosphere, along with a little methane gas

 

CORAL REEFS

Coral is actually a living animal.

has a symbiotic relationship (each gives something to the other and gets something back in return) With ‘zooxanthellae’ microscopic algae which live on coral [i.e. instead of living on the sea  floor, the algae lives up on the coral which is closer to the ocean surface and so that the algae gets lots of light.

The tissues of corals themselves are actually not the beautiful colors of the coral reef, but are instead clear (white). The corals receive their  coloration from the zooxanthellae living within their tissues.

• There are two types of corals: hard corals and soft corals, such as sea fans and gorgonians. Only hard corals build reefs.
• The builders of coral reefs are tiny animals called polyps. As these polyps thrive, grew, then die, they leave their limestone (calcium carbonate) skeletons behind. The limestone is colonized by new polyps.
• found in tropical and sub-tropical water, there are also deep water corals in colder regions
• The United Nations Environment Programme reports that there are more cold water coral reefs worldwide than tropical reefs.
• There are only about 6 different coral species associated in building with these reefs.
• The largest cold-water coral reef is the Rost ‘Reef off Norway occur in shallow tropical areas where the sea water is clean, clear and warm.
• one of the most productive and complex coastal ecosystems with high biological diversity classified depending on their locations into fringing, patch, barrier and atoll.
• The fringing reefs are contiguous with the shore and they are the most common – by occurring reef form, found in Andamans.
• Patch reefs are isolated and discontinuous patches, lying shoreward of offshore reef structures as seen in the Palk bay, Gulf of Mannar and Gulf of Katchchh.
• Barrier reefs are linear offshore reef structures that run parallel to coastlines and arise from submerged shelf platforms. The water body between the reef and the shore is termed as lagoon. Barrier reefs are seen in Nicobar and Lakshadweep.
• Atolls are circular or semi-circular reefs that arise from subsiding sea floor platforms as coral reef building keeps ahead of subsidence. The examples are the atolls of Lakshadweep and Nicobar.
• Among the four major reef areas of India, Andaman and Nicobar Islands are found to be very rich in species diversity followed by the Lakshadweep Islands, the Gulf of Mannar and finally the Gulf of Kachchh.

 

 

Coral Bleaching

 

Bleaching, or the paling of coral colour occurs; when (i) the densities

of zooxanthellae decline and (ii) the concentration of photosynthetic pigments within the zooxanthellae fall.

Ecological causes of coral bleaching

• Temperature (Major Cause)
• Sub aerial Exposure-Sudden exposure of reef flat corals to the atmosphere during events such as extreme low tides, ENSO-related sea level drops or tectonic uplift can potentially induce bleaching.
• Sedimentation
• Fresh Water Dilution
• Inorganic Nutrients(e.g. ammonia and nitrate)
• Xenobiotics -Zooxanthellae loss occurs during exposure of coral to elevated concentrations of various chemical contaminants, such as Cu, herbicides and oil.
• Epizootics

 

KEY INITIATIVES TO PROTECT MARINE AND COASTAL ENVIRONMENTS

 

1. Coastal Ocean Monitoring and Prediction System (COMAPS)

• Being implemented from 1991. Assesses the health of coastal waters and facilitates management of pollution-related issues
• Programme was restructured and modified in 2000 2001 to include pollution monitoring; liaison, regulation and legislation; and consultancy services.

2.Land Ocean Interactions in the Coastal Zone (LOICZ)

 

• Launched in 1995. Investigates the effects of global change on the coastal zone
• Aims to develop, on a scientific basis, the integrated management of coastal environments

3. Integrated Coastal and Marine Area Management (ICMAM)

• Launched in 1998
• Aims at integrated management of coastal and marine areas.
• Model plans for Chennai, Goa and Gulf of Kutch being prepared

4. Society of  Integrated Coastal Management (SICOM)

• Launched in 2010
• Major national initiative to protect coastal ecosystems
• A professional body with experts in various aspects of coastal science and management

5. Institutions for Coastal Management

• The Notification on Coastal Regulation Zone (CRZ), 1991 (as amended from time to time) aims at protecting coastal stretches in India.
• India has created institutional mechanisms such as National Coastal Zone Management
• Authority (NCZMA) and State Coastal Zone Management Authority (SCZMA) for enforcement and monitoring of the CRZ Notification.
• These authorities have been delegated powers under Section 5 of the Environmental (Protection) Act, 1986 to take various measures for protecting and improving the quality-of the coastal environment and preventing, abating  and controlling environmental pollution in coastal areas.
