This study compares the performance of the industrial deep-sea shrimp fishery in the Colombian Pacific prior to and following important management reforms aligned with the FAO Code of Conduct for Responsible Fisheries. The Fishery Performance Indicators (FPIs) methodology was applied to examine changes in the ecological, economic and social outcomes brought about by the reforms. The analysis revealed that regulatory reform improved environmental performance through increases in stock size and

The rebuilding of collapsed fisheries is a major challenge for fisheries science and management, requiring multi-faceted evaluations to assess the current and potential performance of recovering fisheries. Single-dimensional analyses such as stock abundance assessments are only partially effective in determining the best course of action for fisheries in this condition.

The long and persistent swings in the real exchange rate have for a long time puzzled economists. Recent models built on imperfect knowledge economics seem to provide a theoretical explanation for this persistence. Empirical results, based on a cointegrated vector autoregressive (CVAR) model, provide evidence of error-increasing behavior in prices and interest rates, which is consistent with the persistence observed in the data.

This study assessed the livelihood strategies adopted by husbands and wives within the same households for coping with climate-induced food insecurity in Southeast Nigeria. Collective and bargaining approaches were used in collecting individual and intra-household-level data of 120 pairs of spouses in Southeast Nigeria; husbands and wives were interviewed separately. Focus group discussions, key informant interviews, and household surveys were used to elicit responses from the respondents.

Concerns about climate change have required energy policy to be reconsidered around the world. The transition from fossil fuels to renewable energy has the potential to contribute significantly to the goals of the Paris Agreement (2015), particularly in the developing world. The recent evolution of total installed capacity of electricity mix in eight South American countries and the current renewable energy policy is considered.

Access to clean water is one of the 17 Sustainable Development Goals (SDG) to be achieved by 2030, and a priority on the environmental policy agenda in Ethiopia. A main challenge for clean water supply utilities is how to accommodate watershed protection and management costs. The type of land cover around water sources has a notable effect on the cleanliness of the water and hence on water purifying costs.

Researchers and officials interested in people’s attitudes toward risk when designing public policies should make sure that their questions about risk are asked in the specific context of the policy rather than in general abstract questions.

While livestock is an integral component of the mixed crop-livestock farming system in Ethiopia, there is competition between crops and livestock for the limited feed resources. The residue after harvest is one source of livestock feed but has other potential uses, including leaving it on the field to conserve soil and water and reduce weeds. The current practice is open access grazing, in which any farmer’s livestock can eat the residue left on another farmer’s fields.

Local communities in Africa benefit from protected areas through a number of activities such as grazing their livestock and revenues gained from touristic activities such as trophy hunting. These two activities are not independent because the feeding habits of large herbivores such as elephants prevent bush encroachment, thus maintaining healthy grasslands or pastures for livestock.

Zimbabwe’s community-based conservation model, which brings together peasant farmers in a tourism-focused approach to wildlife management, has enjoyed limited success since its inception during the mid-1980s, due to a number of reasons. There has been increased human-wildlife conflict, and it is hard to enforce rules against poaching. Community involvement in wildlife conservation is one of the major factors influencing the success of integrated conservation and development projects. These projects can fail if there is lack of ownership of the project.
