Bangladesh is one of the most vulnerable countries in the world due to climate changes as it is experiencing serious environmental degradation and ecological imbalances. Flooding, too heavy rainfalls or long droughts, cyclones and tornadoes have been rampantly destroying lives and assets. The situation is increasingly critical for maintaining natural resources and for sustaining the livelihoods of many millions of people in the country. In addition to climate change and environmental degradation, air and sound pollution have accentuated the situation for a normal living standards and growth. There is evidence that shows that the goals of environmental protection and economic growth can be complementary. Bangladesh is making its efforts to confront climate change and environmental challenges. To cope with such changes it became imperative to continue efforts not only in mitigation but also to learn adaptation practices to such climatic changes. TMSS has given its full effort for the adaption, mitigation; and conservation of the environment through its programs and projects. Food and nutrition security in Bangladesh is characterized by considerable regional variations within Bangladesh. Factors such as natural disasters, cyclones, tornados, floods and droughts, river erosion; associated with shrinkage of agricultural land due to non-agricultural use is increasingly having negative impact on food production and livelihoods of the millions of people those depended directly and/or indirectly (over 60% of the labour force in Bangladesh is engaged in agriculture sector).
