Submitted by Eugenia Leon on
EfD Authors:

La Flor Wildlife Refuge and nearby beaches on the Pacific coast of Nicaragua are important nesting sites for various species of endangered marine turtles. However, illegal harvesting of turtle eggs threatens the survival of marine turtles. In this study, we analysed the different motivations of local villagers for complying with a ban on harvesting marine turtle eggs in a context, in which government authorities do not have the means to fully enforce existing regulations.

Dynamic Interactions among Boundaries and the Expansion of Sustainable Aquaculture

Submitted by NENRE Concepcion on

We present a novel policy framework to evaluate and pursue growth in aquaculture considering four boundaries: biological productivity, environmental constraints to that productivity, policy that inhibits or promotes different kinds of aquaculture, and social preferences that determine aquaculture markets.

Feasibility of extensive, small-scale mud crab farming (Scylla serrata) in East Africa

Submitted by Salvatory Macha on

Small-scale farming of mud crabs (Scylla serrata) has been suggested as an alternative income for resource poor coastal communities in East Africa. However, it and it is unclear if the present culture methods are profitable and ecologically sustainable at larger scales. Here we assess the two dominant culture methods (crab fattening in cages and grow-out farming in ponds) using economic and ecological analyses in Kenya and Tanzania.

What does it take to be heard in managing marine protected areas? Insights from Tanzania coastal communities

Submitted by Salvatory Macha on

This paper explores the debate on participatory approach by presenting evidence from the local communities practices living within the marine protected area in Tanzania (Mnazi Bay Ruvuma-Estuary Marine Park). Five out of fifteen villages that exist in Mnazi Bay Marine Park were selected for this study after consultation with the park authority. Stratified sampling of villages was conducted based on the location from the Indian Ocean: three villages located close to the sea (sea front villages) and two villages located far from the sea (inland villages).

Disease Risk and Market Structure in Salmon Aquaculture

Submitted by Eugenia Leon on

We develop a model of a multi-national firm producing commodities for a global market in multiple locations with location-specific risks and different regulatory standards. Salmon aquaculture and disease outbreaks provide an empirically relevant example. We specifically examine details of the infectious salmon anemia outbreak in Chile in the late 2000s, the multi-national nature of some firms operating in Chile, and the overall market structure of the salmon farming industry as motivation for our theoretical model.

Firms’ willingness to invest in a water fund to improve water-related ecosystem services in the Lake Naivasha basin, Kenya

EfD Authors:

A valuation scenario was designed using a contingent-valuation approach and presented to decision makers in business firms in Kenya’s Lake Naivasha basin to test how applicable a water fund might be as a potential financing mechanism for a payment for water-related ecosystem services scheme. The findings indicate that measuring a firm’s willingness to invest in ecosystem services could help determine whether a firm would invest and engage with other stakeholders to pool their investments in ecosystem services.

Biosecurity Versus Profits: A Multiobjective Model for the Aquaculture Industry

Submitted by NENRE Concepcion on

In this study, we measure the value of sanitary restrictions in terms of forgone profits. For this, we model the short-run trade-off between biosecurity and profits in the aquaculture industry.
