Success factors for pairing conservation with enhanced forest and fish-based livelihoods

In settings in which people rely directly on either forest or marine resources, protecting both the natural resources and livelihoods is challenging. Findings from Tanzania suggest that, where budgets are limited, key factors for a successful combination of livelihood and conservation policies include the strategic location of livelihood projects that target those most dependent on the protected resource rather than those most likely to cooperate with access restrictions.

Maximising the value of South Africa’s coast

The recreational and aesthetic values of coastal areas have a significant economic impact, and because they are enhanced by coastal protection, the latter should receive top priority in striving to achieve development goals

Formal microlending and adverse (or non-existent) selection: A case study of shrimp farmers in Bangladesh

Microcredit schemes have become a popular means of improving smallholders’ access to credit and making long term investment possible. However, it remains to be explored whether the current microcredit schemes are more successful than earlier formal small scale lending in identifying successful borrowers. We studied shrimp farming in a rural region in Bangladesh where formal microlending is well established, but where more expensive informal microlending coexists with the formal schemes.

The Role of Incentives for Sustainable Implementation of Marine Protected Areas: An Example from Tanzania

Although Marine Protected Areas (MPAs) provide an increasingly popular policy tool for protecting marine stocks and biodiversity, they pose high costs for small-scale fisherfolk who have few alternative livelihood options in poor countries. MPAs often address this burden on local households by providing some benefits to compensate locals and/or induce compliance with restrictions.

Bioeconomic model of spatial fishery management in developing countries

Fishers in developing countries do not have the resources to acquire advanced technologies to exploit offshore fish stocks. As a result, the United Nations Convention on the Law of the Sea requires countries to sign partnership agreements with distant water fishing nations (DWFNs) to exploit offshore stocks. However, for migratory stocks, the offshore may serve as a natural marine reserve (i.e., a source) to the inshore (i.e., sink); hence these partnership agreements generate spatial externality.

Regulatory Compliance in Lake Victoria Fisheries

This analysis of the fishers’ compliance with regulations in Lake Victoria, Tanzania, gives support to the traditional economics-of-crime model and shows that the extension of the basic deterrence model can lead to a richer model with substantially higher explanatory power.

Technical Efficiency and the Role of Skipper Skill in Artisanal Lake Victoria Fisheries

This paper studies technical efficiency and skipper skill (and explores potential proxies), using Tanzanian fishery data for the two major species, Nile perch and dagaa. The relative level of efficiency is high in both fisheries, and several observable variables linked to skipper skill significantly explain the efficiency level. However, given the rapidly depleting fish stocks in Lake Victoria, increased efficiency at the aggregate level is only possible if fishing effort is limited.

Small-scale Fishermen and Risk Preferences

Using an experimental approach, we investigate the risk preferences of artisanal fishermen in Tanzania waters of Lake Victoria. The experiment concerns pairwise comparisons of hypothetical fishing trips that vary in expected mean and spread of the net revenue.

Market Analysis Of Major Fish Product Markets In The Benguela Current Large Marine Ecosystem. BCLME Project LMR/SE/03/02

This report forms just one part of an integrated research effort on the BCLME fisheries being carried out by “The Consortium”. It is anticipated that, as the rest of the BCLME projects advance, new information relevant to this study will come to light. This is particularly true for project LMR/SE/03/03, for example. The Consortium wishes to reserve the right to update this marketing report if and when the relevant information becomes available.

An economic comparison of the commercial and recreational linefisheries in Namibia

The most important Namibian linefish species, the silver kob Argyrosomus inodorus, is currently heavily exploited, and in order to ensure its survival catch restrictions are being introduced. However, kob are exploited both by recreational anglers and by commercial vessels, and it is important to examine the economics of these fisheries in order to determine where catch restrictions will do the least harm to the economy.

Towards an integrated sustainable management of fisheries

This article discusses the underlying causes for the problem of managing fish stocks and the aim of fisheries management.It reviews some of the research development in the area and practical experiences. Further, it deals with the future challenges and discusses potential successful strategies and outlines the necessary conditions for actual progress from the current state.

A Bioeconomic Analysis of the Swedish Fishery for Norway Lobster (Nephrops norvegicus)

A modified version of Jones’ length-based cohort analysis is linked to economic data from the Swedish trawl fishery for Norway lobster (Nephrops norvegicus). The current regulation implies a fishing practice where each landed lobster entails three killed due to discard mortality and different cases of trawl selectivity are compared together with varying natural mortality.

Sustainable Fisheries Law Promotes Reliable Fishing in Chile

 “We make the connection between the fishers’ living conditions and the fish stock’s status.”  The newest EfD Center is not a newcomer to influencing fisheries policy.  The Research Nucleus on Environmental and Natural Resource Economics at the Universidad de Concepcion has been active for several years in bringing an economics perspective into fisheries management in Chile.
