| Many indigenous communities living in the Amazon rely on hunting and fishing to meet the majority of their protein needs. Despite the importance of these practices, few studies from the region have analyzed the socioeconomic drivers of hunting and fishing at the household level. We propose a household production model to assess the effect of key economic parameters on hunting and fishing in small indigenous communities located in the Ecuadorian Amazon, whose principal source of protein is derived from hunting and fishing. The model was validated using empirical data from two communities that reflect different levels of market integration and forest conservation. Demand and supply functions were generated from household data gathered over 19 months.... |

| This article examines the use of Economic Value Added (EVA) as a performance measure that South African wine co-operatives can use to determine whether value has been created for members. A detailed explanation of EVA is given, and the components of EVA are calculated. The EVA's of a number of co-operatives have been calculated and analysed. In addition the EVA of specific types of co-operatives indicate that the fruit and vegetable sector is a constant value creator. It is clear that in order to create value, the rate of return on invested capital must be greater than the cost of capital. Certain co-operatives and types of co-operatives provided the blue print for this. |

| Water management has evolved in the last years towards more integrated and participatory approaches, aiming at improving the adaptability of water systems. Following this line, we propose a methodology to build a decision support system, based on the participation of stakeholders and the integration of the different disciplines involved in water use, as well as the inclusion of uncertainties in the management planning. The process has been implemented in the Upper Guadiana basin (Spain) with the aim of solving the existing conflicts: the aquifer, which is the main water source in the area, has been over-exploited during the last decades for irrigation. This has lead to serious degradation of natural water-related ecosystems and important social conflicts.... |

| This study deals with five settlements (Karos, Karcsa, Pácin, Nagyrozvágy, Cigánd) of Bodrogköz. The main goal of the case-study is to provide a method for the assessment of the economic impacts of land-use planning. The paper shows the connection between economic and land-use models of specific areas. Although the input conditions of the evaluations (e.g. agri-environmental payments) have changed, the framework of the methodology is independent from the input variables, so it can be a useful example for similar assessments. The first part of the study focuses on potential alternative land use options for the region. We suggested changes in land use on the basis of the so-called ’ecotype’ model. In the second part we present the economic evaluation method... |

| The European Union’s sugar policy, in place since 1968, underwent its first major reform in 2005 in response to mounting and unsustainable imbalances in supply and demand. The reform, however, targeted only a few policy instruments (intervention price cut, voluntary production quota buyout, and restrictions on nonquota sugar exports), while leaving other key policies unchanged (interstate quota trading, sugar-substitute competition, and import barriers). Consequently, the extent of the reform’s impact is limited, compared with more far-reaching alternatives, particularly when the oligopolistic nature of the industry and its noncompetitive pricing behavior are taken into account. A model-based analysis suggests that the reforms by themselves are unlikely to... |

| The dependency of small island economies on natural resources coupled with the pubic nature of these resources means that sustainability is a topical issue especially when development projects offer opportunities for "better living" for communities. For a mangrove dependent community of Pangaimotu in Vavau in Tonga tourism development offers better income from employment opportunities. Yet reclaiming mangrove areas for tourism development is likely to impact on fisheries resources that have traditionally been the main form of livelihood for the community. It is argued that for small island communities, whenever development activities ignore the critical role of mangroves on fisheries resources, the wider implications to the community are also overlooked.... |
