Development of an integrated peri-urban wetland degradation assessment approach for the Chatra Wetland in eastern India

Abstract The loss of peri-urban wetlands is a major side effect of urbanization in India in recent days. Timely and proper assessment of wetland area change is essential for the conservation of wetlands. This study follows the integrated way of the peri-urban wetland degradation assessment in the ca...
