The vulnerability of fisheries-based livelihoods to climate variability and change in coastal small pelagic fishing communities in Tanzania

Abstract

Fisheries-based livelihood activities constitute an essential means of income and well-being for the majority living in coastal areas. This paper examines vulnerability of fisheries-based livelihoods caused by climate variability and change. It focuses on three small pelagic fishers’ communities including Kipumbwi, Kilindoni, and Kilwa-Kivinje, along the Tanzanian coast, as a case study. Little research has been done on the effect of climate variability and change on the livelihoods of small-scale fishing communities in developing countries, particularly along the Tanzanian coast. In collecting data, questionnaire, focused group discussion and an interactive governance approach were used. Results showed that the natural vulnerability issues include, reduced catches, and strong winds. Economic vulnerability, mentioned lack of credit facilities. For social vulnerability, respondents mentioned an increased number of fishers and fishing vessels On the aspect of technology, respondents mentioned lack of modern fishing methods. As findings suggest, these vulnerability aspects, are possibly associated with anthropogenic factors such as illegal fishing, may not be related to climate change, but climate change may intensify them. The findings further showed that climate variability has negatively affected the fisheries on which fisher communities depend for income and for food security thus affecting their local economy. Climate change has negatively affected small pelagic fishers. The decline in fish catches and economic- un-matching changes in fish prices have negatively affected the fishing community's income, employment, and food security. The recommended means for reducing vulnerability include reducing taxes and levies, availability of facilities for reducing post-harvesting loss and availability of reliable markets.
