Sustainability of Climate Change Adaptation Practices in South-Western Coastal Area of Bangladesh

Abstract

In Bangladesh, South Western (SW) coastal area is the most vulnerable due to its geo-morphological characteristics and socio-economic conditions. Consequently, this study aims at find out the sustainable adaptation practices to climate change impacts through a series of field study along with questionnaire survey and reviewing the secondary literature. The study shows that near about 50 adaptation practices are exercised in SW coastal area of Bangladesh. Among these, growing local rice variety, rainwater harvesting, directly use of pond water through proper pond management, raising plinth, lowering use roof etc. are the more sustainable adaptation practices. On the other hand, homestead gardening, dyke nursery, cropping on raised mound, school cum cyclone shelter, purification of pond water trough traditional knowledge are the moderately popular and sustainable adaptation practices in terms of social, economic and environmental aspects. Furthermore, shrimp cultivation at homestead, fish-vegetables combined cultivation, purification of pond water through govt. supported filter, pond filter, bamboo made piling house etc. are the less sustainable one.
