Association of Wetland Size Versus Ecological Scenarios and Ecosystem Services With in the Agroclimatic Zone (Namakkal District), Tamilnadu

Abstract

Abstract Stagnant wetlands have a vast natural ecosystem of different sizes, provide vital ecosystem services to humans, but are not well detailed. The study investigates the association of the Stagnant wetland’s size versus the ecological condition (EC), ecosystem service (ES), and their Shifts in land use / land cover (LULC) in the Agro-climatic a location of Namakkal district. Twenty-one chosen wetlands are hydrologically isolated, few semi-parched in summer, surveyed by the range of methods. The Wetland sizes had categorized into small wetlands (SW), medium wetlands (MW), and large wetlands (LW) which, are less than 10 acres, 11 to 100, and above 100 acres, respectively. Our results showed that ES of entire wetlands degraded by human anthropogenic activities and degradation factors differ in the wetland kinds. Also, ecosystem services such as livestock rearing and agronomy are vital income sources. Overall, the hypothesis results show that wetland size is not associated with ecological status and ecosystem services. However, the LULC changes had analyzed from 2010 to 2019. The data corroborate that the increase in constructing the property and extensive changes in agricultural areas are a deep concern for wetland size reduction. Finally, wetlands conservation activities priorities given to are wetlands size-based seems not the best practice.
