Assessing Exposer Intensity Through Remote Sensing And GIS Technology

Vulnerability index, exposer intensity and landscape trajectories is an area of research that integrates people and their activities into natural environment. This type of research is important in natural disaster areas on the globe. The main objective of this type of research is to develop a vulnerability index by combining remote sensing, bio-geophysical and social data. In general, vulnerability is expressed as a function of the exposure, sensitivity and adaptive capacity of a region to natural disasters and climate change effects. Vulnerability research ensures that decisions made about our natural resources incorporate a range of values and perspectives about the meaning, value and use of resources. Presently scientists bring an interest in human values, markets, social organizations and political institutions to the traditional focus of natural science on climate, social and hydrology. It is a reality that natural disasters (such as drought and floods) results in sets of socio-hydrological impacts starting with crop-yield failure, unemployment, erosion of assets, income decrease, poor nutrition and decreasing risk absorptive capacity, thereby increasing the vulnerability.
