The Amazon is the largest tropical forest area on Earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large‐scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These conversions are mostly located in frontier areas distributed along the so‐called “arc of deforestation”. Within this large zone, various land use change processes are interacting through several modes of land valuation and organisation. From several case studies in the State of Pará (Brazil), the current project aims at analysing how landscape dynamics are related to infrastructure development, ecological conditions, zoning policies and to the evolution and the organisation of the production, consumption and marketing chains of livestock products. This paper presents the results for one test site, the region of São Félix do Xingú, South of Pará This region is the focus of land speculation, cattle expansion, and deforestation. Road construction, investments in electrical energy, financial credit for cattle, and the land reform policies have all fuelled this process. All these factors make this region one of the most dynamic agricultural frontiers in the Brazilian Amazon. The main objective of the paper is to improve our understanding of deforestation processes by crossing spatial analyses and 1ivestock economics.studies, and to characterise the role and impact of various natural and anthropic factors in the location and development of the main types of farmers, and their policy implications.  相似文献

Growth and liberalization of world trade have increased the risks of introduction of quarantine plant pests into importing countries. Import inspection of incoming commodities is a major tool for prevention of pest introductions related to world trade, but inspection capacities are limited. This article develops a theoretical and an empirical model for the optimal allocation of inspection effort for phytosanitary inspection of imported commodities when the inspecting agency has a limited capacity. It is shown that the optimal allocation of inspection effort equalizes marginal costs of pest introduction across risky commodity pathways. The numerical illustration finds the optimal allocation of inspection effort of chrysanthemum cuttings imported in the Netherlands. The numerical results suggest that ceteris paribus , greater inspection effort should be allocated to pathways whose inspection yields a greater reduction in the expected costs of pest introduction. The numerical results also suggest that import inspection has a high marginal benefit. In particular, we found that each additional euro of the inspection capacity decreases the expected costs of pest introduction from 18 to 49 euros, depending on the initial inspection capacity.  相似文献

After defining the essential elements of Aristotelian citizenship, the article proposes to apply these criteria in its search for the equivalent of a citizen within the corporate polis. It argues that shareholding managers are the best positioned among a firm’s constituents or stakeholders in fulfilling the role of corporate citizens. Greater participation by management not only in the control but also in the ownership of firms brings about benefits for the firm as a whole and for the managers themselves, as organizational citizenship behavior literature, among others, suggests.  相似文献

Results from statistical analyses of 30 cases of international negotiations supported Iklé's typology of negotiating objectives. The cases, sampled from the collection of Pew Case Studies in International Affairs, were distinguished in terms of five objectives: innovation, redistribution, extension, normalization, and side effects. In addition, a sixth objective was identified: negotiations concerning the creation of multilateral regimes. These cases focused on issues that surfaced on the international agenda during the 1980s. Each type had a relatively distinct profile based on such aspects of negotiation as the number of parties and issues, bargaining strategies, media exposure, stability of the process, and types of outcomes. The methodology contributes to the state-of-the art in comparative analysis and the results have implications for the development of middle-range theories of negotiation. They also contribute to practice, by enabling negotiators to evaluate future cases in terms of knowledge about past cases.  相似文献

Continuing economic development in Jordan provides potential food marketing opportunities as a new group of prospective value-added food product consumers emerges. The growing demand for high-value foods such as organically produced items also provides a new potential value-added market for Jordanian farmers. No studies to our knowledge have examined consumer preferences toward organic food items within Jordan. This study provides an initial attempt to fill this knowledge gap by examining the market for organic food items from a demand perspective in order to increase the knowledge available to Jordanian farmers, food processors, and retailers.  相似文献

This paper reports on empirical research into individual consumer behaviour in the context of fresh fruit and vegetable purchases. The discussion draws on research results from two studies conducted around the actual shopping process. The findings suggest that consumers' price response behaviour may not be consistent with that predicted by economic theory and that this could be significant at the aggregate level. The existence of 'acceptable price ranges' points to the presence of price thresholds within which consumers are relatively insensitive to price movements. Also of relevance is that the primary influence of the budget constraint may be at a broader level rather than at the level of choosing particular products.  相似文献

Public field-afforestation schemes have been designed and widely implemented as a measure to alleviate uneven distribution, generate economic growth in rural areas and maintain or improve natural resources. The literature on forest management and planning has improved land-related information systems, allowing policy-makers to design and implement future policies on the allocation of forestland uses, and to forecast the land requirements of the target population more closely. The aim of this article is to empirically examine and validate the temporal and spatial land use changes and the socioeconomic effects linked to field-afforestation on private lands in the province of Lugo (Galicia, Northern Spain) at the municipal, parish and individual farm holding levels. Two main top-down field-afforestation programmes are reviewed in the study area: the national programme of public afforestations started with the implementation of Ley de Patrimonio Forestal del Estado (National Forest Estate Act; NFE) from 1941 to 2000, and the European aid scheme for forestry measures established under European Council Regulation No. 2080/1992 from 1993 to 1997. The results of a survey, targeted at 1355 farmers and conducted through questionnaires in the province of Lugo in 2004, complete the analysis of public intervention in forest management. The results indicate that the specific social, economic and environmental context of an agricultural and forestry area involves a differential heritage of land customs that determines a differential response model to forest programmes of land allocation and planning. Therefore, this must not be underestimated by the quantitative or qualitative general objectives of large-scale policies.  相似文献

We investigate the value of a country of origin label (COOL) that separately identifies the geographic location of different stages in a food product's supply chain. We estimate the willingness‐to‐pay (WTP) of U.S. consumers for a packaged cereal product where the key grain ingredient may be grown in one country and processed in a second country (multicountry supply chain) and compare it to equivalent products that have both stages located in a single country. We find consumer WTP for products with single‐country and multicountry supply chains are statistically different, meaning that simplifying a multicountry label by listing only the country where the ingredients are grown or only the country where the ingredients are processed can result in different consumer values. We also find that for countries with a poor quality reputation, consumers respond more negatively when that country has the “last touch” than when that country's involvement is limited to upstream supply chain links.  相似文献
