Seaweed harvest has denuded many areas of the sea floor, threatening marine ecosystems and the livelihood of coastal communities. Recently, small operators have begun to cultivate seaweed. This paper studies the role of fishing and agriculture, and their interactions with risk and time preferences, in the uptake of seaweed aquaculture. We use a Heckman selection model to study the decision to participate and expansion of production in seaweed aquaculture in Chile.

AbstractThe ocean, which regulates climate and supports vital ecosystem services, is crucial to our Earth system and livelihoods. Yet, it is threatened by anthropogenic pressures and climate change. A healthy ocean that supports a sustainable ocean economy requires adequate financing vehicles that generate, invest, align, and account for financial capital to achieve sustained ocean health and governance.

Fisheries benefits of a marine protected area with endogenous fishing efforts – A bioeconomic analysis

Submitted by Tali Hoffman on
EfD Authors:
Leiman, Anthony

The study assesses the conservation and fisheries benefits of the Blue Bay Marine Park in Mauritius. It addresses the question - are the higher catch rates near the Park a result of population spillovers or of reduced fishing effort in those waters due to site-specific attributes? There is no data on catches and fishing effort prior to the reserve's establishment; a bioeconomic model is used to separate the effects of spillover and effort redistribution on catch rates in waters next to the Marine Park.
