La agenda ambiental como parte del modelo económico de Colombia
EfD Authors:
Colombia cuenta con un capital natural enorme, derivado de su riqueza en diversidad biológica, sobre el cual puede generar nuevas oportunidades de progreso e inclusión económica. Al mismo tiempo, el país enfrenta retos ambientales muy importantes asociados a sus profundas desigualdades, debilidad institucional para cumplir sus compromisos internacionales, y para cumplir el mandato de la Constitución de 1991, una de las cartas más verdes de tiempos recientes.
Do Chilean imports lead prices in the EU mussel market?
EfD Authors:
The impact that added competition of imported mussels from Chile might have had on market prices is one of the main reasons given to explain the decrease in the economic performance of the mussel aquaculture sector in the European Union (EU) in the last two decades. This hypothesis has not yet been tested. In this article we test empirically for price leadership and market integration in the EU mussel market. We estimate a cointegrated vector autoregressive (CVAR) model for the French, Italian, and Spanish mussel import markets and test for price leadership.
The performance of shared fish stock fisheries under varying institutional and socioeconomic conditions: Evidence from the South Eastern Pacific Anchoveta Fishery
EfD Authors:
We apply the Fishery Performance Indicators (FPIs) methodology to the Southeast Pacific Anchoveta Fishery off southern Peru and northern Chile. Our basic model of analysis is a production function framework, where the performance outcomes are a result of the available inputs. We measured all FPI categories (outcomes and input metrics) and then grouped the metrics into different dimensions suitable for analysis. We obtained the value of each metric from different sources using expert evaluation and secondary information.
MPAs and Aspatial Policies in Artisanal Fisheries
EfD Authors:
Using a spatially explicit framework with low/middle-income country coastal characteristics, we explore whether aspatial policies augment the impact of marine protected areas(MPAs)and identify when MPAs create income burdens on communities. When MPAs are small and budget-constrained, they cannot resolve all of the marinescape’s open-access issues, but they can create win-win opportunities for ecological and economic goals at lower levels of enforcement.
From theory to action: Explaining the process of knowledge attitudes and practices regarding the use and disposal of plastic among school children
Environmental education is regarded as a key instrument for promoting pro-environmental behavior in early childhood. In this paper, we analyze the transmission process within a personal value system including knowledge, attitudes, and practices (KAP) regarding the consumption and disposal of plastics among school children, and the extent to which parents play a role in mediating that transmission. The study gathers data from a sample of 1,521 children in southern Chile.
Feeding the dragon: The evolution of China’s fishery imports
EfD Authors:
This paper examines the changing face of China’s imports of fisheries products from the beginning of its market-oriented growth in the early 1990s to the present. We demonstrate how import demand has evolved by species group and country and examine the implications of these changes for the diversification of China’s sourcing of fisheries products. We also examine how China’s trade partners have changed in terms of governance and IUU risk.
Determinants of Catfish Farmers’ Use of Sustainable Environmental Management Practices in Enugu State, Nigeria
EfD Authors:
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
EfD Authors:
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.
