Impact of Climate Change on Ecological Sensitivity of Wetlands
The ratio of eco-friendly to eco-foe land use can be defined as the ecological sensitivity of a region. If the area of eco-friendly land use is more within the targeted range, then that area is designated as ecologically suitable, and if most of the region within the observed area has an eco-foe land use, then the area of interest is said to be ecologically sensitive. The degree of sensitivity and suitability varies with the dominance of eco-foe and eco-friendly land use within the investigated area. Currently, the increase in greenhouse gases in the atmosphere has increased the average temperature of the Earth’s surface, which in turn has engendered uncertainties in normal climatic patterns, a situation that is aggravated due to the constant and uncontrolled extraction of natural resources, which has impacted the natural ecosystem of many regions of the world. The impact of climatic uncertainty has also severely affected the ecological conditions of wetlands. Thus, there is an urgent need for impact analysis for wetlands with respect to changes in ecological patterns of wetland watersheds. The present study aims to estimate the degree of uncertainty induced by changes in climatic patterns with the help of ecologic sensitivity and NASA’s (Climate change may bring big ecosystem changes.

The present investigation has used the decision tree algorithm for the prediction of the ecological sensitivity of Tripura wetlands. Tripura is a state in northeast India undergoing rapid urbanization. The results of the study could help city planners to develop compensatory measures specific to those regions that urgently need them.
