Abstract

Wetlands are the areas of marsh, fen, peat land 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 meters. Wetland plays a significant role in regional ecosystem, such as the regulation of climate, cleansing of environment and balancing of regional water. The wetland provides critical habitat for a large number of flora and fauna. In India, the total area under wetlands was estimated to be 11.69 m ha. This accounts for 3.66 per cent of geographic area of the country. In Assam, total wetland area estimated is 764372 ha that is around 9.74 per cent of the geographic area. Wetlands act as important repositories of aquatic biodiversity. The present paper is an attempt to investigate the human activities including agricultural practices and the influence of solid waste causing a significant change in the land use,landcover and subsequent loss of wetlands. The present paper will discuss human interference and its impact on some selected wetlands of Golaghat district of Assam. The data analyzed and presented in this paper is based on both primary and secondary data (collected from different sources).
