FAO  defines food security as 'a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life'. There is significant evidence that climate change significantly undermines both agricultural production and food security in Asia . Increasing evidence from sub-regions and individual countries suggests that climate-related hazards, such as increasing temperature, changing rainfall, SLR, drought, flooding and the more frequent and intense occurrences of El Niño- Southern Oscillation events, all impact agricultural production with significant effects on food security. All these hazards interact with non- climatic factors, such as competing demand for scarce water resources, rural-urban migration, food prices and increasing food demand in the
