"Myanmar is a resource-rich country bordered by India, Bangladesh, China, Laos, and Thailand. It is the second-largest country in Southeast Asia, with a third of its perimeter comprising an uninterrupted coastline that spans 1,930 kilometers along the Bay of Bengal and Andaman Sea. Agriculture is very important in Myanmar?s economy: it employs 70% of the country?s labor force and comprises 38.2% of its GDP. Rice is considered both a major food crop and major export food item. The majority of Myanmar?s sown area is planted to monsoon rice, whereas summer rice is planted between November and February in the delta region in the country?s lower part and from January to March in central dry-zone regions. Myanmar is among the world?s most vulnerable countries to climate change. One of its manifestations that is seen to seriously affect the country?s rice production capacity is heat stress."
