Wetlands

Basics –

  • Wetlands are areas where water covers the soil all year or for varying periods of time during the year.
  • Wetlands experience periodic flooding from adjacent deepwater habitats
  • Wetlands are considered amongst the most productive ecosystems in the world
  • Wetlands include
  • Marshes or swamps where water gets stagnated due to poor drainage or relatively impervious substrata
  • Flood plains – areas lying adjacent to river channels beyond the natural levees and periodically flooded during high discharge in the river
  • Mangroves
  • Littorals – marginal areas between highest and lowest water level of the lakes
  • Peat lands, Bogs and fens

Functions of Wetlands –

  • Biodiversity protection
  • support a great diversity of species, many of which are unique and rare
  • Water storage
  • water is stored in the soil or retained in the surface waters of lakes, marshes etc
  • Groundwater replenishment
  • part or the water filters into the ground and recharges underground aquifers (groundwater reservoirs)
  • Sediment retention
  • by slowing down the force of water, encouraging the deposing of sediments carried in the water
  • High biological productivity – nutrients are often associated with sediments and can be deposited at the same time
  • Retention of nutrients
  • wetland species effectively remove nitrogen and phosphorous from agricultural and industrial discharges
  • leads to prevention of eutrophication further downstream
  • Storehouse (sinks) of carbon
  • Wetlands act as significant carbon sinks – the destruction of wetlands will release carbon dioxide
  • Source of livelihood to local people
  • cattle graze on some types of wetland vegetation which may also be used as an addition to forage, etc
  • Buffer shorelines against erosion
  • Aesthetic and educational value, support for tourism

Causes of destruction –

  • Conversion of wetlands for agriculture
  • Removal of sand from beds
  • Climate change
  • Deforestation
  • Habitat destruction
  • Aqua Culture
  • Pollution
  • Domestic waste
  • Industrial effluents
  • Agricultural runoff

Loss of Wetland causes –

  • Increased flooding events
  • Decline in water quality
  • Loss of wildlife habitat

Ramsar Convention

About –

  • Convention on Wetlands (Ramsar, Iran, 1971)
  • Ramsar convention is an international treaty that provides the framework for conservation and sustainable use of wetlands
  • It is named after the city of Ramsar in Iran, where the Convention was signed in 1971
  • It came into force on December 21, 1975
  • Objectives
  • Conservation of all wetlands through local and national actions and international cooperation
  • Sustainable use of wetlands and all the services they provide, for the benefit of people and nature

Organization –

  • Headquarters: Ramsar Convention secretariat is located in Gland, Switzerland, shared with the IUCN.
  • Presently there are 169 contracting parties, up from 21 initial signatory nations in 1971
  • The state parties meet every three years as the conference of the contracting parties (COP)
  • There is a standing committee, a scientific review panel, and a secretariat
  • Contracting parties commit to work through national plans, policies and legislation management actions and public education
  • Ramsar Convention works closely with fire other organisations
  • Bird life International
  • International Union for conservation of nature (IUCN)
  • International water management institute (IWMI)

  • WWF International

Importance of wetlands –

  • The term wetland includes
  • all lakes and rivers, underground aquifers, swamps and marshes
  • wet grasslands, peat lands oases, estuaries, deltas and tidal flats
  • coral reefs, mangroves and other coastal areas
  • all human-made sites such as fish ponds, rice paddies, reservoirs and salt pans
  • Wetlands are among the most diverse and productive ecosystems.
  • Wetlands provide essential services such as
  • freshwater supply, food and building material, and biodiversity
  • flood control, groundwater recharge, and climate change mitigation
  • Issue –
  • Wetlands are degradation and converted to other uses
  • Wetlands should be restored and rehabilitated, whenever possible

Transboundary Ramsar Site –

  • It does not, however, address the movement of radioactive waste

Objectives –

  • to minimize the amount and toxicity of waste generated
  • to ensure their environmentally management as closely as possible to the source of generation
  • to assist LDCs in environmentally sound management of the hazardous and other wastes they generate

Formation –

  • It came into force on 5 May 1992
  • 182 states and the European Union are parties to the convention
  • Haiti and the United States have signed the convention but not ratified it

A waste falls under the scope of the convention if –

  • It is within the category of wastes listed in Annex I of the convention and
  • It exhibits one of the hazardous characteristics contained in Annex III.
  • It is considered to be a hazardous waste under the laws of either the exporting country, the importing country, or any of the countries of transit

Bamako Convention

About –

  • Bamako convention on the ban on the import into Africa and the control of trans boundary movement and management of hazardous wastes within Africa

Facts –

  • Impetus for the Bamako convention arose from the failure of the Basel convention to prohibit trade of hazardous waste to less developed countries (LDCs)

United Nations Framework Convention on Climate Change (UNFCCC)

Background –

  • UNFCCC is an international environment treaty negotiated at the United Nations conference on environment and development (UNCED)
  • UNCED is informally known as the Earth Summit which held in Rio de Janeiro from 3 to 14 June 1992
  • The UNFCCC was adopted on 9 May 1992, and it entered into force on 21 May 1994
  • Objective –
  • To stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system
  • It is legally non-blinding treaty
  • The treaty provides a framework for negotiating specific international treaties (called “protocols”) that may set blinding limits on greenhouse gases
  • The work under the UNFCCC is facilitated by a secretariat in Bonn, Germany
  • Classification of Parties –

Annex I –

  • There are 43 parties to the UNFCCC listed in Annex I of the convention
  • These parties are classified as industrialized countries and “economies in transition (EITs)

Annex II –

  • These are 24 parties to the UNFCCC listed in Annex II of the convention
  • These parties are made up of members of the organization for economic cooperation and development (OECD)

Annex B –

  • Parties listed in Annex B of the Kyoto Protocol are Annex I Parties with first or second round Kyoto greenhouse gas emissions targets
  • Least development countries (LDCs)
  • 49 parties are LDCs, and are given special status under the treaty in view of their limited capacity to adapt to the effects of climate change
  • Non-Annex I
  • Parties to the UNFCCC not listed in Annex I of the convention are mostly low-income developing countries.
  • Conference of Parties (COPs) –
  • After the signing the UNFCCC treaty, parties to the UNFCCC have met at conference to discuss how to achieve the treaty’s aims

  • Flexibility mechanisms –
  • International emissions trading (IET)
  • allows parties to the Kyoto protocol to buy Kyoto units(emission permits for greenhouse gas) from other countries to help meet their domestic emission reduction target
  • Clean development mechanisms (CDM)
  • Through the CDM countries can meet their domestic reduction targets by buying greenhouse gas reduction units from non Annex I countries to the Kyoto Protocol.
  • Non-Annex I countries have no GHG emission restrictions, but have financial incentive to develop GHG emission reduction projects to receive certified emission reductions that can then be sold to Annex I countries
  • Joint Implementation (JI)
  • through the joint implementation any Annex I country can invest in emission reduction projects in any other Annex I country as an alternative to reducing emissions domestically
