Among the natural disasters, flood is one of the most common and widely spread disasters across the world. In India, the north eastern state of Assam is one of the most complex fluvial systems of rivers mainly with two inter-connected river valleys namely Brahmaputra and Barak which together enters the bay of Bengal. In 2009 NESAC has initiated Flood Early Warning System for Assam as a pilot exercise for Lakhimpur. Presently it is operationalized for all the districts of Assam
Forest fires are a major environmental problem in North East Region (NER) with large tracts of forest areas are being affected in every season. Forest fires have become a major cause of forest degradation. NESAC with an aim to support the forest fire management authorities and the ongoing forest fire mitigation programs took the initiative to map fire incidents in the region with near real time and historical data analysis. NESAC is providing Forest Fire Risk Zones in the locations where forest fire is occurring during the fire season .
Landslides are important denudational processes in mountainous areas that frequently damages means of communication and transportation besides creating loss to the life and property. Detection of landslide and identification of the affected area is a key requirement for planning post-disaster rescue and relief operations as well as landslide susceptibility and hazard assessment. NESAC has prepared landslide hazard zonation, vulnerability assessment, risk assessment maps has been prepared for Guwahati city
Thunderstorm is one of the major disasters affecting the entire NE region and particularly the states of Assam, Tripura, Mizoram and Meghalaya. There are severe loss of life and property from the thunders and associated wind every year over these regions. Early warning of thunderstorm with actionable lead time has the potential to save these lives and minimize loss of property. NESAC has initiated thunderstorm now casting on experimental basis for the western Assam, Meghalaya, Mizoram, and Tripura states during the pre-monsoon season of the year 2016
