Abstract

Sustainable development (SD) policies targeting marine economicsectors, designed to alleviate poverty and conserve marine ecosystems,have proliferated in recent years. Many developingcountries are providing poor fishing households with new fishingboats (fishing capital) that can be used further offshore as a meansto improve incomes and relieve fishing pressure on nearshore fishstocks. These kinds of policies are a marine variant of traditionalSD policies focused on agriculture. Here, we evaluate ex anteeconomic and environmental impacts of provisions of fishing andagricultural capital, with and without enforcement of fishingregulations that prohibit the use of larger vessels in nearshorehabitats. Combining methods from development economics, naturalresource economics, and marine ecology, we use a uniquedataset and modeling framework to account for linkages betweenhouseholds, business sectors, markets, and local fish stocks. Weshow that the policies investing capital in local marine fisheries oragricultural sectors achieve income gains for targeted households,but knock-on effects lead to increased harvest of nearshore fish,making them unlikely to achieve conservation objectives in ruralcoastal economies. However, pairing an agriculture stimulus withincreasing enforcement of existing fisheries’ regulations may leadto a win–win situation. While marine-based policies could be animportant tool to achieve two of the United Nations SustainableDevelopment Goals (alleviate poverty and protect vulnerable marineresources), their success is by no means assured and requiresconsideration of land and marine socioeconomic linkages inherentin rural economies.
