| A falta de conhecimento da aptidão de uso da terra e do planejamento adequado da sua utilização tem sido fato freqüente ocasionando impactos negativos ao meio ambiente. Neste sentido, os objetivos deste trabalho foram determinar a aptidão de uso, uso atual e os conflitos de uso da terra, visando contribuir para o planejamento racional dos recursos naturais no município de São João do Polêsine (SJP), RS. A análise ambiental foi efetuada através da integração de diferentes planos de informações como solos, relevo, hidrografia, aptidão agrícola, uso das terras e áreas de preservação permanente (APP). SJP apresenta mais de 50% de sua área destinada a atividades agropecuárias, 14,8% do município enquadra-se como APP, sendo a metade dessa área utilizada... |

| Consumers face pressure from environmental groups to modify their seafood purchase decisions based on concerns about fisheries' production practices. Existing research provides little information indicating whether seafood consumers are willing to change purchasing behavior based on a product's environmental attributes, to the exclusion of other attributes. We describe a contingent ranking experiment addressing preferences for fresh seafood, allowing for choices among different species, some displaying an ecolabel. Results suggest consumers consider overfishing sufficiently important to contemplate changing the species of fish they buy; however, they are unwilling to choose a less-favored species based solely on the presence of an ecolabel. |

| This paper investigates the EKC curves for CO2 emissions in a panel of 109 countries during the period 1959-2001. The length of the series makes the application of a heterogeneous estimator suitable from an econometric point of view. The results, based on the hierarchical Bayes estimator, show that different EKC dynamics are associated with the different sub samples of countries considered. On average, more industrialized countries show an EKC evidence in quadratic specifications, which are nevertheless probably evolving into an N shape, emerging from cubic specifications. Less developed countries consistently show that CO2 emissions still rise positively with income, though some signals of an EKC path arise. |

| The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with heterogenous environments. Protected areas are analysed under density-dependent and sink-source dispersal relationships between environments within the fishery. Differing levels of management control over fishery resource extraction are analysed. The model is applied to Manning Bioregion in NSW. The focus of the study is placed on the biological and institutional characteristics that yield benefits to the fishery. |

| The Cottonwood River Watershed is located in southwestern Minnesota, draining 1,310 square miles of land within the Minnesota River Basin. The watershed is comprised of parts of Brown, Cottonwood, Lyon, Murray, and Redwood Counties. This essay gives a brief account of the initial European settlement of the area and the establishment of the current political boundaries. It then focuses on the major developments in agricultural production during the past 150 years, touching on the changes in landscape and wildlife due to drainage and restructuring of water bodies and the clearing of forest land. |

| Average total factor productivity measures for the dairy industry provide an insight into how the industry is performing as a whole, but reveal little about what may be happening on individual farms. A case study of an irrigated dairy farm in northern Victoria, over a 37-year period, found that total milk production and some measures of partial productivity increased substantially. The economic performance of this case study farm over the 37-year period is described and analysed. From records of income and expenses, operating profit, returns to capital, labour and management and total productivity measures were calculated. Between 1980 and 2000, the business achieved productivity gains at higher than the rate estimated for the whole industry. This... |

| In 1904 Eugène Dubois published the first report on fossil mammals from the vicinity of Tegelen. After a century of research the clay-pits from the area are known as a classical locality for Villafranchian mammals. Antje Schreuder's work was particularly important for making the fossils from Tegelen known. Her papers, however, also indicate some problems. The large mammal fossils were gathered by clay-workers in the local ceramic industry, and the fragmentary nature of the fossils is partly caused by injudicious handling while extracting the bones from the clay. Because the Tegelen fossils are chance finds rather than the results of careful excavations, their exact provenance is not established. The only exception is the collection of micromammals, which... |

| In this study, we employ the Harbinson proposal and July Framework to compare a ‘likely’ Doha scenario with an ‘inclusive’ baseline. The key aim is to assess the impacts across EU member states. More specifically, we (i) employ the latest version 6 of the GTAP database, (ii) explicitly model CAP mechanisms (e.g., quotas, decoupled payments, set-aside, CAP budget etc.) to more accurately assess the asymmetric trade led welfare effects on selected EU member states, and (iii) introduce binding overhangs into domestic support, export subsidies and more importantly market access commitments. Whilst the EU regions benefit from the multilateral reform proposals, the gains are weakened considerably by the tariff binding overhangs, where the EU25 only gain ten per... |

| The study has revealed that the total cost per hectare is higher in Bt cotton than hybrid cotton. The cost of seeds has been found higher in Bt cotton, whereas hybrid cotton growers incur more cost on insecticides/ pesticides. This shows the effectiveness of the new technology (Bt cotton) for insect resistance. The average total cost of production as well as the bulk line cost have been found lower in Bt cotton. This depicts a reduction in the unit cost of Bt cotton, which is the distinct advantage of the new technology. A higher yield of 29 per cent has been obtained by the Bt cotton farmers over the hybrid cotton growers. The study has identified the constraints in production, and marketing of Bt cotton in the area. Bt cotton has been found a superior... |
