Status and Threats of Wetland Change in Land Use Pattern and Planning

Abstract

Wetland-related studies documented the loss of native species diversity and promotion of the biotic homogenization due to wetland loss. Excessive withdrawals of water from wetlands for residential, agricultural, or industrial use are responsible for wetland degradation. Constructions of dams impedes water flow and replenishment of wetlands, and it also creates a hazard to aquatic living organisms. Climate change causing some wetlands to disappear under rising sea levels, while others are severely impacted by changing climatic conditions, including drought. So necessary steps such as increase wetlands and prevention of the illegal swamping of wetlands, etc. should be taken for conserving the wetland biodiversity from the threatening of unplanned urbanization, purifying the environment and mainlining the sustainable development. Though the Ramsar Convention policy exists to persevere wetlands and achieve sustainable development throughout the world, mass consciousness, greater participation of local people, use of indigenous knowledge in the management strategies are needed to protect wetlands.
