Om Prakash Sharma, IFS Director DEE&RS, J&K INTRODUCTION Wetlands covering about six per cent of the earth surface, are among the world's most productive environments and by providing sufficient water and the primary productivity, they sustain and harbour a vast range of biological diversity. Local and regional importance of wetlands is even more pronounced and pivotal from both ecological and socioeconomic viewpoints. More than three billion people, around half the world's population, obtain their basic water needs from inland freshwater wetlands. The same number of people relies on rice as their staple food, a crop grown largely in natural and artificial wetlands. In some parts of the world, almost the entire local population relies on wetland cultivation for their livelihoods. In addition to food, wetlands supply fibre, fuel and medicinal plants. WHAT ARE WETLANDS? Wetlands are areas where water is the primary factor controlling the environment and the associated plant and animal life. They occur where the water table is at or near the surface of the land, or where the land is covered by shallow water. ❖ According to most widespread definition wetlands are defined as: "lands transitional between terrestrial and aquatic eco-systems where the water table is usually at or near the surface or the land is covered by shallow water". ❖ Ramsar Convention on Wetlands define wetlands as: "areas of marsh, fen, peatland or 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 six metres". Five major wetland types are generally recognized: • Marine (coastal wetlands including coastal lagoons, rocky shores, and coral reefs); • Estuarine (including deltas, tidal marshes, and mangrove swamps); • Lacustrine (wetlands associated with lakes); • Riverine (wetlands along rivers and streams); and • Palustrine (meaning “marshy” – marshes, swamps and bogs). In addition, there are human-made wetlands such as fish and shrimp ponds, farm ponds, irrigated agricultural land, salt pans, reservoirs, gravel pits, sewage farms and canals. The Ramsar Convention has adopted a Ramsar Classification of Wetland Type which includes 42 types, grouped into three categories: • Marine and Coastal Wetlands, • Inland Wetlands, and • Human-made Wetlands. Quick Info: Wetlands occur everywhere, from the tundra to the tropics. How much of the earth’s surface is presently composed of wetlands is not known exactly? The UNEP-World Conservation Monitoring Centre has suggested an estimate of about 570 million hectares (5.7 million km2); roughly 6% of the Earth’s land surface; Mitsch and Gosselink, in their standard textbook Wetlands, 4th ed. (2007), suggest 4 to 6% of the Earth’s land surface. Mangroves cover some 240,000 km2 of coastal area, and an estimated 600,000km2 of coral reefs remain worldwide. Nevertheless, a global review of wetland resources prepared for Ramsar COP7 in 1999, while affirming that “it is not possible to provide an acceptable figure of the areal extent of wetlands at a global scale”, indicated a ‘best’ minimum global estimate at between 748 and 778 million hectares. The same report indicated that this “minimum” could be increased to a total of between 999 and 4,462 million hectares when other sources of information were taken into account. WHY CONSERVE WETLANDS? Access to safe water, human health, food production, economic development and geopolitical stability are made less secure by the degradation of wetlands driven by the rapidly widening gap between water demand and supply. Even with current attempts to maintain water flows for ecosystems, the capacity of wetlands to continue to deliver benefits to people and biodiversity, including clean and reliable water supplies, is declining. Efforts to support water allocation to ecosystems, such as environmental flows, placing upper limits on water allocations, and new water management legislation, must be strengthened. The multiple roles of wetland ecosystems and their value to humanity have been increasingly understood and documented in recent years. This has led to large expenditures to restore lost or degraded hydrological and biological functions of wetlands. Functions: The interactions of physical, biological and chemical components of a wetland, as part of the “natural infrastructure” of the planet, such as soils, water, plants and animals, enable the wetland to perform many vital functions. Values: Wetlands frequently provide tremendous economic benefits, including water supply (quantity and quality); fisheries (over two thirds of the world’s fish-harvest is linked to the health of wetland areas); agriculture, through the maintenance of water tables and nutrient retention in floodplains; timber and other building materials; energy resources, such as peat and plant matter; wildlife resources; transport; a wide range of other wetland products, including herbal medicines; and recreation and tourism opportunities. In addition, wetlands have special attributes as part of the cultural heritage of humanity – they are related to religious and cosmological beliefs and spiritual values, constitute a source of aesthetic and artistic inspiration, yield invaluable archaeological evidence from the remote past, provide wildlife sanctuaries, and form the basis of important local social, economic, and cultural traditions. In the Millennium Ecosystem Assessment (MA), published in 2006, ecosystems are described as the complex of living communities (including human communities) and non-living environment (Ecosystem Components) interacting (through Ecological Processes) as a functional unit which provides a variety of benefits to people (Ecosystem Services). Included in the term “Ecosystem Services” are provisioning, regulating, and cultural services that directly affect people, and supporting services which are needed to maintain these other services.
