A study was conducted in four selected upazilas under four coastal districts through participatory rural appraisal (PRA),
household survey and monitoring, sampling, focal group discussions, personal interview, onfarm field visits, institutional
consultations, and secondary information. The investigation revealed that the valuable natural resources of the whole region
are at the verge of serious degradation. Various causes have been identified, which are responsible for degradation of both
resources and production environments. These causes include human population growth, coastal embankment, upstream withdrawal
of Ganges water, brackish water shrimp farming, salt production, use of agro-chemicals, industrial activities, commercial
activities, over-exploitation, etc. The study also showed that the degradation of natural resources is the reason behind the
squeezing of historically dominant livelihood opportunities of the coastal communities. The current scenarios of the coastal
ecosystem urge necessary steps to be taken for sustainable management of valuable resources and to create alternative livelihood
opportunities for the coastal communities. 相似文献
