CLIMATE CHANGE IN NORTHEAST INDIA: RECENT FACTS AND EVENTS - WORRY FOR AGRICULTURAL MANAGEMENT

摘要

The Northeastern Region of India is expected to be highly prone to the consequences to climate change because of its geo-ecological fragility, strategic location vis-a-vis the eastern Himalayan landscape and international borders, its trans-boundary river basins and its inherent socio-economic instabilities. Environmental security and sustainability of the region are and will be greatly challenged by these impacts. The region fall under high rainfall zone with subtropical type of climate. Still, under influence of global climate change even high rainfall areas are facing drought like situations in the current years. Droughts and floods are the adverse climatic conditions arising out of deficit and excess rainfall, respectively. Drought assumes significance mainly in rainfed conditions like in North East India. Unprecedented drought like situation affected very adversely the whole NER in recent years. Special reference may be made for the year 2005, 2006, 2009. Floods are equally devastating in the region. The increasing melting of glaciers in Himalayas are great concern for the region. In the absence of scientific data about the vulnerability of the region to climate change, conservation agriculture, afforestaion, rain water harvesting, efficient use of inputs, following proper agro-techniques for management of drought are some of the management options that needs to be immediately popularized among the farming communities to mitigate the impact of climate change.
