This is a study of the impact of local ecological changes, global warming and coastal flooding on fishing communities in the Mumbai suburbs of Manori, Gorai and Uttan (administratively, Uttan is in the neighbouring Thane district). The objective was to find how ecological and climate changes have affected, or are likely to affect, fishing communities and their livelihood, and their perceptions of the reasons for the changes, if any. The focus was on the vulnerabilities of artisanal and small-scale fishers.
