Drought Vulnerability Detection And Mapping In Thrissur District, A Part Of Southern Western Ghats, India- Using Geoinformatics
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 11
Abstract
Drought is an insidious phenomenon. Unlike rapid onset disasters, it tightens its grip over time, gradually destroying an area. In most cases, drought can last for many years .The impacts of drought vary from lack of adequate drinking water, loss of vegetation, loss of farmland, loss of livestock and loss of life due to famine or dehydration. Drought can be divided into four categories of meteorological, hydrological, agricultural and socioeconomic. In this study the vulnerability of drought in Thrissur district is investigated by providing vulnerability maps which demonstrates spatial characteristics of drought vulnerability. Thrissur is also called as “cultural capital of Kerala”, south India. The modern technology used in present system for drought prone area identification is remote sensing and geographic information system. Drought is one of the climatic, natural disasters, having an impact on both the economy and the society, with its long-standing problems. Drought by nature is a result of inter-related parameters. The study is based on the concept that the severity of the drought is a function of rainfall, hydrological and physical aspects of the landscape, leading to meteorological, hydrological and physical drought. In the present study a Geographic Information Systems (GIS) and remote sensing -based tool for drought vulnerability assessment at a micro level has been developed. The result of this study can be used for preparedness planning and for allocating resources for facing droughts in this region.
