Wild mushroom picking is a growing recreational and commercial activity. In Spain, wild mushrooms legally belong to the landowner, who seldom benefits from trade in mushrooms or from their recreational value. Cultural aspects (tradition, picker-related harms) and economic aspects (costly forestry works, income opportunities) constitute elements of the debate on how to deal with mushroom picking. Through a survey of private forest owners in Catalonia (north-eastern Spain), this paper examines their experiences with mushroom pickers, the factors shaping their related policy preferences and their willingness to engage in mushroom reserves.The results show broad support for introducing mushroom picking norms. A regulation would allow outsider pickers to enter private land, but only under certain conditions, i.e. to comply with socio-ecological rules of the area. Among respondents who support the regulation, active land owners who report instances of picker-related harm (both tangible and intangible) tend to support the establishment of a fee system which could be reinvested into forest management. That is also the position of the respondents who perceive mushrooms as a private right, i.e. they believe to have a legitimate right to exclude outsider pickers and, eventually, to raise revenues from that asset. On the contrary, forest owners who conceive mushroom picking as a free-access activity prefer neither to regulate it nor to charge fees. The option to establish a mushroom picking reserve depends on the landholder being a fee-supporter and perceiving instances of harm. Harm, instead, is mainly determined by the perception of congestion of pickers, which in turn is determined by the mushroom productivity of their forest, their level of privacy protection and their involvement to the primary sector. These findings help policymakers to better understand the logic and sensitivities of forest owners in view of designing mushroom picking policies that can effectively solve picker-landowner conflicts.  相似文献

Traditional models of economic development such as economic base and urban revitalization models have been found wanting. Both models rely on expert-based assessments of local development needs. More recent approaches call for a stronger focus on local development needs and resident skills as the basis for designing development strategies. One such neighborhood-based approach to development is presented in this paper. Its initial step was a survey of 444 households representing 1398 residents conducted in the Hamilton Hill and Vale neighborhoods of Schenectady, New York a 'downsized' community of about 65,000 residents in the Capital District of New York State. Survey results show a strong need for recreation, childcare, a grocery store, care for the elderly and home repairs. Residents' self-assessed job skills and interests appear to be well suited to meet these needs. Yet despite these promising results, barriers to neighborhood-based development persist. These barriers reiterate the long history of isolation prevalent in US inner city neighborhoods. Two issues are particularly characteristic of the barriers that continue to keep urban neighborhoods isolated from their larger context. They are: (1) a lack of effective communication between local residents and decision makers; and (2) a lack of valuation systems that properly assess the value of social and environmental context and their contributions to local development.  相似文献

课程重要程度是一个至今没有被定义的概念。如何评价课程重要程度 ,是科学规划课程必须解决的难题。各国课程理论却没有深入研究这一问题。近年来 ,部分学者探索用价值工程、系统工程等管理技术分析课程问题 ,并提出了一些评价方法 ,如打分法、排序法等。但由于至今对课程重要程度的概念理解不一 ,评价结果偏差很大 ,实际效果不理想。本文首先对课程重要程度进行定义 ,并在深入分析的基础上 ,提出了主要评价指标及其关系模型。同时为了模型应用方便 ,提出应用模型应注意的主要问题和相关建议 ,以及用模糊数学评判结果的思路和方法。  相似文献

Managing agricultural floodplains to meet present and future human requirements without jeopardizing biodiversity conservation is a challenge for land use planners and ecologists. This paper aims to disentangle the relationships between ecosystem services and biodiversity in multifunctional landscapes, such as floodplain agroecosystems, by disaggregating their values across land use types. We measured eight ecosystem services (gas regulation, soil formation, nutrient regulation, habitat provision, food provision, raw materials production, education, and recreation) and six plant diversity indexes (richness, abundance, and true diversity for both plant species and growth forms) in seven land use types identified in the floodplain of the River Piedra (Spain). We observed that all land use types provided services to some extent, but each one was better at providing certain services. Natural or semi-natural habitats provided more services and hosted greater diversity than cultivated land use types. In addition, five diversity indexes were strongly correlated to at least three ecosystem services each one. Habitat provision and education were the ecosystem services positively correlating to most diversity indexes, whereas food provision was negatively correlated to all diversity indexes. Moreover, analyzing the interactions between ecosystem services and biodiversity across land use types, we observed that land use type was the controlling factor regarding the sign and significance of the interaction. The results of this study suggest that, in floodplains agroecosystems, a mosaic landscape of different land use types helps support ecosystem services and contributes to maintaining biodiversity while using local resources. Such land use policies might manage agricultural floodplains at the landscape scale while still being able to accommodate specific measures for each land use type. Moreover, riparian forests should be preserved and restored across the floodplain as they are hot spots for biodiversity and ecosystem services provision.  相似文献
