Determinants of Catfish Farmers’ Use of Sustainable Environmental Management Practices in Enugu State, Nigeria

Submitted by Agha Inya on

The study assessed the use of sustainable environmental management practices (SEMP) by fish farmers in Enugu state, Nigeria. Seventy-five catfish farmers selected through multistage sampling procedure were used for the study. Data were obtained with the aid of a well-structured questionnaire. Analysis of data was done using descriptive statistics, probit regression model and factor analysis. Results showed that most of the catfish farmers did not apply SEMP as only 25.33% of them had a score of 50% and above regarding the application of SEMP.

Productivity response and production risk: A study of mangrove forest effects in aquaculture in the Mekong River Delta

Submitted by Luat Do on

In Vietnam, most households that are allotted rights to mangrove forests are allowed to convert forestland into surface water to build mixed mangrove-shrimp farming systems. One result has been deforestation in mangrove forests in an effort to increase production. However, mangroves play multiple roles in shrimp yield, and their net effect is an empirical question. In addition, mangroves can reduce production risk, such that clearing mangroves can increase risk.

Impact assessment of salmon farming on income distribution in remote coastal areas: The Chilean case

Submitted by Cristóbal Vásquez on

We analyzed the impact that the advent of the salmon aquaculture industry had on income distribution in coastal communities. Specifically, we evaluated whether salmon farms generated significant changes on household income distribution in the remote coastal areas of the Los Lagos region in Chile between 1992 and 2002. Salmon farms were expected to generate new labor and income opportunities for the local population. The impact on income distribution in the area should depend on which type of households were favored with this increased labor demand: low-income or high-income households.

Assessing public preferences for deep sea ecosystem conservation: a choice experiment in Norway and Scotland

Submitted by Luat Do on
EfD Authors:

Recent events around the world have revealed varying degrees of public support for climate change and environmental regulation. Applying a latent class logit model, this study investigates Norwegian and Scottish public’s economic support for proposed deep sea management policies for novel attributes, identifying the presence of preference heterogeneity. Marine litter and health of fish stocks were the attributes with the highest values in absolute terms. This was followed by the size of the protected area coverage, whilst the creation of jobs was the least valued.

Subsidies—Help or Hurt? A Study from Vietnamese Fisheries

Submitted by Luat Do on
EfD Authors:

Subsidies are part of the set of management tools that governments apply to modernize their fishing fleets and enable them to engage in offshore and international fisheries. Research has shown that subsidies often lead to overcapacity and overfishing, resulting in the depletion of fish stocks. A few studies, however, have found some positive effects for particular subsidies. In this paper, we investigate a credit-linked subsidy scheme in Vietnam, which seems to be justified on the basis of economic, social, and environmental considerations.

Low propensity to move and marine resource-based livelihood choices for coastal communities in southern Chile

Submitted by Petra Hansson on

Abstract: In this paper, we describe and analyze an experience in the use of marine resources as a base for economic activities and development of coastal communities. According to the economic theory of the commons, Chile’s establishment of unique property and user rights for marine resources should reduce over-extraction pressure from open access and thereby improve sustainability of marine resources.
