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

• 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.

Wetland Conservation Programme

• 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
• Wetlands of India under Ramsar Convention

The Montreux Record. Sites on the List of Wetlands of International Importance which are considered to have undergone, to be undergoing, or to be likely to undergo change in their ecological character brought about by human action may be placed on the Montreux Record and may benefit from the application of the Ramsar Advisory Mission and other forms of technical assistance.

• Keoladeo national park and Loktak lake from India are included in the list

Changwon Declaration

The primary purpose of the  “Changwon Declaration on human well-being and wetlands”,adopted by Resolution X.3 of the recent meeting of the Conference of the Parties, “is to transmit key messages concerning wetland-related issues to the many stakeholders and decision-makers beyond the Ramsar community who are relevant to the conservation and wise use of wetlands, to inform their actions and decision-making”

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

• 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 pillars of 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 a value system. It is not a scientific formula.
• Thinking beyond pure self-gratification to awareness that harm to one will eventually be harm to all.
• Interconnectedness and 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 approach has 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 1988 emphasizes 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^th FYP. In all States and UTs
  • Formed by merger of two 9^th FYP 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 21 was 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

Under the Cancun Agreements, the targets set by industrialised countries for reduction of greenhouse gas emissions are recognised as part of the multilateral process. They must now draw up low-carbon development plans and strategies and also report their inventories annually. In the case of developing countries, actions for emissions reduction will be recognised officially; a registry will record and match their mitigation actions to finance and technology support from rich countries; and they will report their progress every two years. These form a good preamble for target-setting for all member-countries under an agreed framework at Durban next year.

Trivia

• A large amount of energy used during the conference came from renewable sources
• Around 10000 trees and bushes will be planted in Cancun

Role of India and its relevance

• India can act as a mediator between the developing and developed countries
• India’s approach to climate change negotiations has been governed by three factors – how to protect the country’s economic interest and environment agenda, to use climate change as a tool of global diplomacy and consolidate its position on world forums.
• At Cancun, India was responsible for having made five insertions into the Agreement
  • In the section on shared vision, the figure of 50 pc has been dropped from identifying a global goal for substantially reducing emissions by 2050
  • The phrase access to sustainable development has been introduced in the context of working towards identifying a time-frame for global peaking of greenhouse gas emissions based on the best available scientific knowledge
  • International Consultation and Analysis (ICA) finds mention the agreements. It proposes to enhance the reporting for the non-Annex 1 parties or developing countries on mitigation  action and its effects and support received
• At Cancun, India also proposed legally binding emission cuts.

Movement of these pollutants involves two main processes:

1. Bioaccumulation

refers to how pollutants enter a food chain. there is an increase in concentration of a pollutant from the environment to the first organism in a food chain.

2. Biomagnification

refers to the tendency of pollutants to concentrate as they move from one trophic level to the next.  there is an increase in concentration of a pollutant from one link in a food chain to another.

In order for biomagnification to occur, the pollutant must be: long-lived, mobile, soluble in fats, biologically active.

If a pollutant is not active biologically, it may biomagnify, but we really don’t worry about it much, since it probably won’t cause any problems Examples : DDT.

The components of the ecosystem is categorised into abiotic of non-living and biotic of living components. Both the components of ecosystem and environment are same.

1. Abiotic Components

the inorganic and non-living parts of the world.  consists of soil, water, air, and light energy etc.  involves a ,large number of chemicals like oxygen, nitrogen-, etc. and physical processes including volcanoes, earthquakes, floods, forest fires, climates, and weather conditions.

Abiotic factors are the most important determinants of where and how well an organism exists in its environment. Although these factors interact with each other, one single factor can-limit the range of an organism.

1. a) Energy

Energy from the sun is essential for maintenance of life. Energy determines the distribution of organisms in  the environment.

1. b) Rainfall
2. c) Temperature :-Temperature is a critical factor of the environment which greatly influences survival of organisms. Organisms can tolerate only a certain range of temperature and humidity.
3. d) Atmosphere :It is made up of 21% oxygen, 78% nitrogen , 0.038% carbon dioxide and other inert gases  (0.93% Argon, Neon etc).
4. e) Substratum :Land is covered by soil and a wide variety of microbes, protozoa, fungi and small animals (invertebrates) thrive in it
5. f) Materials:

(i) Organic compound

Such as proteins, carbohydrates,  lipids,  humic  substances are formed from inorganic compound on decomposition.

(ii) Inorganic compound

Such as carbon,   carbon dioxide, water, sulphur, nitrates, phosphates, and ions of various metals are essential for organisms to survive.

1. g) Latitude and altitude

Latitude has a strong influence on an area’s temperature, resulting in change of climates such as polar, tropical, and temperate. These climates determine different natural biomes. From sea level to highest peaks, wild life is influenced by altitude. As the altitude increases, the air becomes colder and drier, affecting wild life accordingly.( wild life decrease as altitude increase)

2. Biotic Components :Biotic components include living organisms comprising plants, animals and microbes and are classified according to their functional attributes into producers and consumers.

Primary producers – Autotrophs (self-nourishing) Primary producers are basically green plants (and certain bacteria and algae). They synthesise carbohydrate from simple inorganic raw materials like carbon dioxide and water in the presence of sunlight by the process of photosynthesis for themselves, and supply indirectly to other non- producers.

In terrestrial ecosystem, producers are basically herbaceous and woody plants, while in aquatic ecosystem producers are various species of microscopic algae.

1. b) Consumers — Heterotrophs or phagotrophs (other nourishing)

Consumers are incapable of producing their own food (photosynthesis).

They depend on organic food derived from plants, animals or both.

Consumers can be divided into two broad  groups

(i) Macro consumers- They feed on plants or animals or both and are categorised on the basis of their food sources.

Herbivores are primary consumers which feed mainly on plants e.g. cow, rabbit.

Secondary consumers feed on primary consumers e.g. wolves.

Carnivores which feed on secondary consumers are called tertiary consumers e.g. lions which can eat wolves.

Omnivores are organisms which consume both plants and animals e.g. man.

(ii) Micro consumers – Saprotrophs (decomposers or osmotrophs)

They are bacteria and fungi which obtain energy and nutrients by decomposing dead organic substances (detritus) of plant and animal origin.

The products of decomposition such as inorganic nutrients which are released in the ecosystem are reused by producers and thus recycled.

Earthworm and certain soil organisms (such as nematodes, and arthropods) are detritus feeders and help in the decomposition of organic matter and are called detrivores.
