Impacts of Anthropogenic Land Use/Land Cover on the Distribution of Invasive Aquatic Macrophytes in Tropical Floodplains: a Case Study from the Barak River Basin in Northeast India
- 57 Downloads
Tropical floodplains are low-lying areas that experience periodic flooding from adjacent rivers and wetlands (Junk and Welcomme 1990). Various aquatic ecosystems such as oxbow lakes, wetlands, ponds, swamps, rivers, and small streams, which are vital components of a floodplain landscape, perform ecosystem services estimated to be worth ~US$ 3920 billion per year (Tockner and Stanford 2002). They also provide a productive environment for economic activities such as agriculture, fisheries, and mining (Junk 1997).
The floodplains in India are home to diverse flora and fauna. They are also the zones of significant economic and socio-cultural activities and hence prone to environmental degradation. A recent study showed that nearly half of the Indian subcontinent is climatically suitable for invasion by diverse alien species (Adhikari et al.2015), substantially comprised of the floodplains of the major rivers: the Ganga, Brahmaputra, Barak, Mahanadi, Brahmani, Baitarani,...
