Assessing vulnerability to climate change using Geographical Information Systems (GIS)

The anticipated impacts of the climate change in Tanzania are increase in temperature, change in precipitation patterns, rise in sea level. Subsequently, an upscale in frequency and intensity of droughts and floods is expected, with adverse effects on human health, agriculture and livelihood.

Thus, it is important to map those areas which are more exposed to adverse events, sensitive to get affected and have lesser adaptive capacity to deal with or combined are more vulnerable to climate risks. In order to quantify the vulnerability, a 4-step approach should be applied.

The 4-step approach of vulnerability assessment is a function of three components, namely exposure, sensitivity, and adaptive capacity. These are calculated individually and then in the fourth step, all the individual three scores (for exposure, sensitivity and adaptive capacity) are overlaid to get an estimate of vulnerability. We present in this study how vulnerability to climate risks varies across different villages/towns/districts in our target area. 

Vulnerability mapping in this study would help in identifying the areas that might be worst affected in case of calamities like flood and drought and other extreme weather events.

Thanks.

ECOLOGICAL RESTORATION IS VERY IMPORTANT IN OUR COUNTRY DUE TO HIGHLY DEGRADED ZONES BY HUMAN INFLUENCES AND OTHER MINOR NATURAL EVENTS.

THIS WILL HELP TO COMBAT THE NEW EMERGENT ISSUE, CLIMATE CHANGE.
