Areas of marsh, fen, peatland/water, whether natural (or) artificial, permanent (or) temporary with water that is static (or) flowing, fresh, brackish (or) salt, including areas of marine

water the depth of which at low tide does not exceed 6 mtrs.

Wetlands Classification-

1. Inland wetland-

a)Natural- Lakes / Ponds, Ox-bow Lakes, Waterlogged, Swamp/marsh

1. b) Manmade- Reservoirs Tank, Ash pond
2. Costal Wetland-
3. A) Natural- Coral reef, Tidal flat, Mangroves, Salt marsh, Estuary, Lagoon, Creek,

Backwater, Bay

b)-manmade -• Salt pans, Aquculture

Functions of Wetlands-

• Habitat to aquatic flora and fauna, birds
• Filtration of sediments and nutrients from surface water,
• Nutrients recycling, Water purification Floods mitigation,
• Ground water recharging, Buffer shorelines against erosion,
• Genetic reservoir for various species of plants(rice)
• the National Lake Conservation Programme (NLCP) considers lakes as standing water
• bodies which have a minimum water depth of 3 m, generally cover a water spread of more than ten hectares, and have no or very little aquatic vegetation.
• Wetlands (generally less than 3 m deep over most of their area) are usually rich in nutrients (derived from surroundings and their sediments) and have .abundant growth of aquatic macrophytes

India’s Wetland

Wetlands occupy 18.4% of the country’s area of which 70% are under paddy cultivation.

Inland wetlands >Costal Wetlands

 

National Wetlands Conservation Programme (NWCP)

• NWCP was implemented in the year 1985-86.
• Under the programme, 115 wetlands have been identified by the Ministry which require urgent conservation and management interventions.

Aim

• Conservation of wetlands to prevent their further degradation and ensuring their wise
• use for the benefit of local communities and overall conservation of biodiversity.

Objectives

• to lay down policy guidelines for conservation and management of wetlands in the country.
• to provide financial assistance for undertaking intensive conservation measures in the identified wetlands
• The Central Government is responsible for overall coordination of wetland
• conservation programmes and initiatives at the international and national levels. It also provides guidelines, financial & technical assistance to state govt.
• State Governments/UT Administration are responsible for management of wetlands and implementation of the NWCP for ensuring their wise-use

 

Criteria for Identification of Wetlands of National Importance

Criteria for identification of wetlands of national importance under NWCP are same as those prescribed under the ‘Ramsar Convention on Wetlands’ and are as given below:

1. Sites containing representative, rare or unique wetland types

example of a natural or near-natural wetland type’ found within the appropriate biogeographic region.

2. Criteria based on species and ecological communities

• If it supports vulnerable, endangered, or critically endangered species; or
• threatened ecological communities.
• If it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.
• If it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.

 

3. Specific criteria based on water birds

• If it regularly supports 20,000 or more water birds.
• If it regularly supports 1% of the individuals in a population of one species or subspecies of waterbirds.

 

4. Specific criteria based on fish

• If it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages,  species  interactions  and/or  populations  that  are representative of wetland benefits and/or values and thereby contributes to global biological diversity.
• If it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.

5. Specific criteria based on water/life and culture

• If it is an important source of food and water resource, increased possibilities for recreation  and eco-tourism, improved scenic values, educational opportunities, conservation of cultural heritage (historic or religious sites)

 

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.

• 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 activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods”

 

• 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.

 

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

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

 

 

Any – body of standing water, generally large enough in area and depth, irrespective of its hydrology, ecology, and other characteristics is generally known as lake.

Ageing of Lakes

The nutrient enrichment of the lakes promotes the growth of algae, aquatic plants and various fauna. This process is known as natural eutrophication.

Similar nutrient enrichment of lakes at an accelerated rate is caused by human activities and the consequent ageing phenomenon is known as ‘cultural eutrophication’.

In India, natural lakes (relatively few) mostly ile in the Himalayan region, the floodplains of Indus, Ganga and Brahmaputra.

Lake ‘Sudarshan’ in Gujarat’s Girnar area was perhaps the oldest man-made lake in India, dating back to 300 BC.

Lakes are also classified on the basis of their water chemistry. Based-on the levels of salinity, they are known as Freshwater, Brackish or Saline lakes (similar to that of classification of aquatic ecosystem).

On the basis of their nutrient content, they are categorized as Oligotrophic (very low nutrients), Mesotrophic (moderate nutrients) and Eutrophic (highly nutrient rich).

Removal of the nutrients from a lake

• Flushing with nutrient-poor waters.
• Deep water abstraction.
• On-site P-elimination by flocculation/flotation with water backflow, or floating Plant
• NESSIE with adsorbents.
• On-site algae removal by filters and P-adsorbers.
• 0n-site algae skimming and separator thickening.
• Artificial mixing / Destratification (permanent or intermittent).
• Harvest of fishes and macrophytes.
• Sludge removal

EUTROPHICATION

a syndrome of ecosystem, response to the addition of artificial or natural substances such as nitrates and phosphates through fertilizer, sewage, etc that fertilize the aquatic ecosystem.

The growth of green algae which we see in the lake surface layer is the physical identification of an Eutrophication.

Some algae and blue-green bacteria thrive on the excess ions and a population explosion covers almost entire surface layer is known as algal bloom.  Nitrogen testing is a technique to find the optimum amount of fertilizer required for crop plants. It will reduce the amount of nitrogen lost to the surrounding area.

 

 

HARMFUL ALGAL BLOOMS

Algae or phytoplankton are microscopic organisms that can be found naturally in coastal waters. They are major producers of oxygen and food for many of the animals that live in these waters.

Algal blooms can be any color, but the most common ones are red or brown.

Most algal blooms are not harmful but some produce toxins and do affect fish, birds, marine mammals and humans.

Use of algae

Most species of algae or phytoplankton serve as the energy producers at the base of the food web, without which higher life on this planet would not exist.

Why Red Tide is a misnomer?

“Red Tide” is a common name for such a phenomenon where certain

phytoplankton species contain pigments and “bloom” such that the human eye perceives the water to be discoloured.

Blooms can appear greenish, brown, and even reddish orange depending upon the type of organism, the type of water, and the concentration of the organisms.

The term “red tide” is thus a misnomer because blooms are not always red, they are not associated with tides, they are usually not harmful, and some species can be harmful or dangerous at low cell concentrations that do not discolour the water.

What are the causes of these blooms?

Two common causes are nutrient enrichment and warm waters.

 

Fresh water ecosystems- The salt content of fresh bodies is very low, always less than 5 ppt  (parts per thousand). E.g lakes, ponds, pools, springs, streams, and rivers

Marine ecosystems – the water bodies containing salt concentration equal to or above that of sea water (i.e., 35 ppt or above). E.g shallow seas and open ocean   Brackish water ecosystems- these water bodies have salt content in between 5 to 35 ppt. e.g. estuaries, salt marshes, mangrove swamps and forests.

 

AQUATIC ORGANISMS

The aquatic organisms are classified on the basis Of their one of occurrence and their ability to cross these zones. can be classified on the basis of their life form or location into five groups

1. Neuston:

These are unattached organisms which live at the air-water interface such as floating plants, etc.

Some organisms spend most of their lives on top of the air-water interface such as water striders, while others spend most of their time just beneath the air-water interface and obtain most of their food within the water.

E.g., beetles and back-swimmers.

2. Periphyton:

These are organisms which remain attached to stems and leaves of rooted plants or substances emerging above the bottom mud such as sessile algae and their associated group of animals.

3. Plankton

This group includes both microscopic plants like algae (phytoplankton) and

animals like crustaceans and protozoans (zooplankton) found in all aquatic

ecosysteins, except certain swift moving waters

The locomotory power of the planktons is limited so that their distribution is

controlled, largely, by currents in the aquatic ecosystems.

4. Nekton:

This group contains animals which are  swimmers.

The nektons are relatively large and powerful as they have to overcome the water currents.

5. Benthos:

The benthic organisms are those found living in the bottom of the water mass.

Practically every aquatic ecosystem contains well developed benthos

Factors Limiting the Productivity of Aquatic Habitats

1. Sunlight :

Sunlight penetration rapidly diminishes as it passes down the column of water.

The depth to which light penetrates a lake determines the extent of plant distribution.

Based on light penetration and plant distribution they are classified as photic and aphotic zones

Photic zone:

It is the upper layer of the aquatic ecosystems, up to which light penetrates and within which photosynthetic activity is confined.

The depth of this zone depends on the transparency of water.

photic (or .”euphotic”) zone is the lighted and usually well-mixed portion that extends from the lake surface down to where the light level is 1% of that at the surface.

Aphotic zone:

The lower layers of the aquatic ecosystems, where light penetration and plant growth are restricted forms the aphotic zone.

Only respiration activity takes place.(photic-both respiration and photosynthesis take place )

Aphotic zone is positioned below the littoral and photic zones to bottom of the lake where light levels are too low for photosynthesis.

This deep, unlit region is also known as the profundal zone.

Dissolved oxygen:

Oxygen enters the aquatic ecosystem through the air water interface and by the photosynthetic. average concentration of dissolved oxygen as 10 parts per million by weight.

Dissolved oxygen escapes the water body through air-water interface and through respiration of organisms (fish, decomposers, zooplanktons, etc )

The amount of dissolved oxygen retained in water is also influenced by temperature.

Other limiting factors which influence on aquatic productivity are

Transparency:

Transparency affects the extent of light penetration.

Suspended particulate matters such as clay, silt, phytoplankton, etc make the water turbidity. Consequently it limits the extent of light penetration and the photosynthetic activity in a significant way.

Temperature:

The water temperature changes less rapidly than the temperature of air because water has a considerably higher specific heat than air.

Since water temperatures are less subject to change, the aquatic organisms have narrow temperature tolerance limit.

 

 

Forest ecosystem includes a complex assemblage of different kinds of biotic communities. Optimum conditions such as temperature and ground moisture are responsible for the establishment of forest communities.

Forests may be evergreen or deciduous which are distinguished on the basis of leaf into broad-leafed or needle leafed coniferous forests in the case of temperate areas. classified into three major categories: coniferous forest, temperate forest and tropical forest.

All these forest biomes are generally arranged on a gradient from north to south latitude or from high to lower altitude

 

Coniferous forest (boreal forest):

Cold regions with high rainfall, strong seasonal climates with long winters and short summers

evergreen plant species such as Spruce, fir and pine trees, etc and by animals such as the lynx, wolf, bear, red fox, porcupine, squirrel, and amphibians like Hyla, Rana, etc.

Boreal forest soils are characterized by thin podozols and are rather poor. Both because, the weathering of rocks proceeds slowly in cold environments and because the litter derived from conifer needle (leaf  is decomposed very slowly and is not rich in nutrients.

These soils are acidic and are mineral deficient.

This is due to movement of large amount of water through the soil, without a significant counter-upward movement of evaporation, essential soluble nutrients like calcium, nitrogen and potassium which are leached sometimes beyond the reach of roots. This process leaves no alkaline oriented cations to encounter the organic acids of the accumulating litter.

The productivity and community stability of a boreal forest are lower than those of any other forest ecosystem.

Temperate deciduous forest:

The temperate forests are characterised by a moderate climate and broad-leafed deciduous trees, which shed their leaves in fall, are bare over winter and grow new foliage in the spring.

The precipitation is fairly uniform throughout.

Soils of temperate forests are podozolic and fairly deep.

Temperate evergreen forest:

Parts of the world that have Mediterranean type of Climate are characterised by warm, dry summers and cool, moist winters. low broad leafed evergreen trees.

Fire is an important hazardous factor in this ecosystem and the adaptation of the plants enable them to regenerate quickly after being burnt.

Temperate rain forests:

seasonality with regard to temperature and rainfall

Rainfall is high, and fog may be very heavy. It is the important source of water than rainfall itself

The biotic diversity of temperate rain forests is high as compared to other temperate forest.

the diversity of plants and animals is much low as compared to the tropical rainforest.

 

Tropical rain forests:

 

Near the equator.

Among the most diverse and rich communities on the earth.

Both temperature and humidity remain high and more or less uniform.

The annual rainfall exceeds 200 cm and is generally distributed throughout the year.

The flora is highly diversified The extreme dense vegetation of the tropical rain  forests remains vertically stratified with tall trees often covered with vines, creepers,   lianas, epiphytic orchids and bromeliads.

The lowest layer is an understory of trees,  shrubs, herbs, like ferns and palms.

Soil of tropical rainforests are red latosols, and they are very thick

Tropical seasonal forests:

also known as monsoon forest occur in regions where total annual rainfall is very high but segregated into pronounced wet and dry periods.

This kind of forest is found in South East Asia, central and south America, northern Australia, western Africa and tropical islands of the pacific as well as in India.

Subtropical rain forests:

Broad-leaved evergreen subtropical rain forests are found in regions of fairly high rainfall but less temperature differences between winter and summer

Epiphytes are common here.

Animal life of subtropical forest is very similar to that of tropical rainforests.

 

INDIAN FOREST TYPES

Forest types in India are classified by Champion and Seth into sixteen types.

 

Tropical Wet evergreen forests

are found along the Western Ghats, the Nicobar and Andaman Islands and all  along the north-eastern region.

It is characterized by tall, straight evergreen trees.

The trees in this forest form a tier pattern:

Beautiful fern of various colours and different varieties of orchids grow on the trunks of the trees.

Among the following States, which one has the most suitable climatic conditions for the cultivation of a large variety of orchids with minimum cost of production, and can develop

Tropical Semi-evergreen forests

found in the Western Ghats, Andaman and Nicobar Islands, and the Eastern

Himalayas.

Such forests have a mixture of the wet evergreen trees and the moist

deciduous trees. The forest is dense

Tropical Moist deciduous forests

found throughout India except in the western and the north -western regions.

The trees are tall, have broad trunks, branching trunks and roots to hold them firmly to the ground.

These forests are dominated by sal and teak, along with mango, bamboo, and rosewood.

Littoral and swamp

found along the Andaman and Nicobar Islands and the delta area of the Ganga and the Brahmaputra.

They have roots that consist of soft tissue so that the plant can breathe in the water.

Tropical Dry deciduous forest

The northern part of the country except in the North-East. It is also found in Madhya Pradesh, Gujarat, Andhra Pradesh, Karnataka, and Tamil Nadu. The canopy, of the trees does not normally exceed 25 metres.

The common trees are the sal, a variety of acacia, and bamboo.

Tropical Thorn forests

This type is found in areas with black soil: North, West, Central, and South India. The trees do not grow beyond 10 metres. Spurge, caper, and cactus are typical of this region.

Tropical Dry evergreen forest

Dry evergreens are found along Tamil Nadu Andhra Pradesh and Karnataka coast. It is mainly hard-leaved evergreen trees with fragrant flowers, along with a few  deciduous trees.

Sub-tropical Broad-leaved forests

Broad-leaved forests are found in the Eastern Himalayas and the Western Ghats, along the Silent Valley.

There is a marked difference in the form of vegetation in the two areas.

In the Silent Valley, the  poonspar, cinnamon, rhododendron, and fragrant grass are predominant.

In the Eastern Himalayas, the flora has been badly affected by the shifting cultivation and forest fires.

There are oak, alder, chestnut, birch, and cherry trees. There are a large variety of orchids, bamboo and creepers.

Sub-tropical Pine forests

found in Shivalik Hills, Western and Central Himalayas, Khasi, Naga, and Manipur Hills.

The trees predominantly found in these areas are the chir, oak, rhododendion, and   pine as well as sal, amla, and laburnum are found in the lower regions.

 

Sub-tropical Dry evergreen forests

hot and dry season and a cold winter. It generally has evergreen trees with shining

leaves that have a varnished look.

found in the Shivalik Hills and foothills of the Himalayas up to a height of 1000 metres.

Montane Wet temperate forests

In the North, found in the region to the east of Nepal into Arunachal Pradesh, receiving a minimum rainfall of 2000 mm. In the North, there are three layers of    forests: the higher layer has mainly coniferous, the middle layer has deciduous trees such as the oak and the lowest layer is covered by rhododendron and champa.

In the South, it is found in parts of the Niligiri Hills, the higher reaches of Kerala.

The forests in  the northern region are denser than in the South. Rhododendrons and a

variety of ground flora can be found here.

Himalayan Moist temperate Forest

This type spreads from the Western Himalayas to the Eastern Himalayas. The trees

found in the western section are broad-leaved oak, brown oak, walnut,

rhododendron,

Eastern Himalayas, the rainfall is much heavier and therefore the vegetation is also more lush and dense. There are a large variety of broad-leaved trees, ferri, and  bamboo.

Himalayan Dry temperate Forest

This type is found in Lahul, Kinnaur, Sikkim, and other parts of the Himalayas.

There are predominantly coniferous trees, along with broad-leaved trees such as the oak, maple, and ash. At higher elevation, fir, juniper, deodar, and chilgoza are found.

 

Sub alpine forest

Sub alpine forests extend from Kashmir to Arunachal Pradesh between 2900 to 3500 metres.

In the Western Himalayas, the vegetation consists mainly of juniper, hododendron, willow, and black currant.

In the eastern parts, red fir, black juniper, birch, and larch are the common trees.

Due to heavy rainfall and high humidity the timberline in this part is higher than that in the West.

Rhododendron of many species covers the hills in these parts.

Moist Alpine scrub

Moist alpines are found all along the Himalayas and on the higher hills near the Myanmar border. It has a low scrub, dense evergreen forest, consisting

mainly of rhododendron and birch. Mosses and ferns cover the ground in patches. This region receives heavy snowfall.

Dry alpine scrub

Dry alpines are found from about 3000 metres to about 4900 metres. Dwarf plants predominate, mainly the black juniper, the drooping juniper, honeysuckle, and willow.

 

 

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
