How researchers describe groups living within or near the world's tropical rain forests has important implications for how and why these groups are targeted for assistance by conservation and development organizations. This article explores how data about market behavior can be used to assess one aspect of forest peoples’ livelihoods: their “dependence” on forest resources as a source of market income. With the intent of revealing the importance of methodology to how we describe forest peoples’ livelihoods, I draw from a multiyear survey of market activity among the Tawahka Sumu of Honduras and distinguish nested measures of the Tawahkas’ engagement in forest‐product sale. Results indicate that whether or not the Tawahka —or any forest group — can be considered financially “dependent” on forest resources depends on the spatial and temporal scales at which data are aggregated. As a group, the Tawahka earned 18 percent of total market income from forest‐product sale, but their group profile masked a high degree of heterogeneity at the village and household level. Similarly, multiyear data indicated that while group‐level generalizations adhere from year to year, they belie considerable change in households’ market behavior across years. I discuss three ways in which the findings are relevant to the theory and practice of conservation and development in the humid tropics. I emphasize the importance of spatial scale in interventions, how market‐oriented conservation schemes can benefit from a broader conceptualization of the economic context in which forest‐product sale occurs, and how longitudinal analysis can reveal the dynamism of forest peoples’ livelihoods. 相似文献

Out-migration from rural areas and generational shifts create conditions whereby increasing numbers of private forest owners live at a distance from their forestland. Geographical distance and non-residency have been raised as issues that may possibly weaken these owners’ relationships with their properties. Drawing on the “sense of place” concept as a frame of analysis for 51 qualitative interviews with resident and nonresident private forest owners from two areas in Sweden, this study provides in-depth understanding of how geographical distance and place of residency shape owners’ feelings about their forest properties. The study shows that sense of place is constructed in complex and multifaceted ways over time and that social and historical contexts and processes beyond the forest environment can make owners feel closeness to their distant properties. Thus, geographical distance or residency alone does not explain variations in these forest owners’ feelings of distance or closeness to their properties. 相似文献

There is a major trend in forest management that local managers are being replaced by entrepreneurs, who are often less place-dependent. Entrepreneurs are also more updated when it comes to scientific knowledge and national and international trends in forest values and functions, as well as knowledge about general planning and management concepts that have high value for tourism and recreation. Parallel with the observed changing management culture, there also seems to be an increased abstraction of forest values and functions in forest certification programmes. The article briefly presents some key aspects of Aldo Leopold's thinking that are of relevance for forest stewardship, and discusses these in relation to main forest stewardship trends in a Nordic forestry context. In a Nordic tradition, forest management and planning are deeply rooted in local management practice carried out by official local supervisors in cooperation with forest owners and other stakeholders. Local traditions and accumulated local knowledge over time were, in addition to updated scientific knowledge, important skills for local managers. Today's post-modern forestry includes complex multi-valued forest situations on different scales, which are even more complex and challenging to manage than the more utilitarian historical forest was. 相似文献

Previous studies have shown that environmental values of inhabitants of urban areas differ to some extent from those of people living in rural contexts. In the light of increasing urbanization, it is sometimes argued that these differences are becoming even greater, as people are becoming more and more alienated from nature. In the context of a larger survey study on beliefs about forests and forest management among the general public in Germany and Sweden, the influences of people’s migration biographies on their patterns of forest usage, their environmental concerns about forests, and the expectations and values they ascribe to forests are explored. While previous findings on differences between urban and rural populations are confirmed, we also find variation within these groups depending on their history of moving between the two spatial categories. This study thus adds a dynamic aspect to the discussion on the urban–rural perspective on beliefs about forests. 相似文献

Experiences and issues of using cellular automata for assisting urban and regional planning in China 总被引：1，自引：0，他引：1

Since the late 1990s, there are growing studies on the development of cellular automata (CA) as a simulation tool for assisting urban and regional planning in China. Rapid urban development is the main reason that this country has become one of the best places to test the methodology of CA and analyze the effectiveness of using these models. This paper attempts to summarize the experiences and issues of using CA to solve various environmental and planning problems in China. The analysis is based on the literature review using the search engines of ISI Web of Science and Google Scholar. These experiences could be important for those who want to apply CA in developing countries. For example, which environmental and ecological problems can be solved by using this bottom-up approach? What are the data inputs to these models and how can they be calibrated? Our analyses indicate that CA have the great potential to support land-use planning and policy analysis for fast-growing regions. Some specific features of using CA in China are also identified in the literature review, including delineation of urban growth boundary, prevention of illegal development and formulating zoning schemes. The CA studies in this fast-growing country provided valuable experiences for other developing countries to solve a series of simulation and planning problems by using this bottom-up approach. 相似文献

Rationalizing tax increment financing in Chicago 总被引：1，自引：1，他引：0
Benjamin F. Teresa 《Urban geography》2017,38(2):199-220
A central problem in planning is how planners can be both technical experts and political actors sensitive to the moral consequences of planning. Rationality refers to the reasons for choosing a means to achieve an end; a rationality that considers the morality of means and ends is value rationality, and one that does not is instrumental rationality. Through the case of using Tax Increment Financing (TIF) to subsidize corporate headquarters relocation in Chicago, I follow City follows planners’ struggle with TIF policy and their engagement with instrumental and value rationality within a state that exercised an entrepreneurial planning strategy. This position meant that planners were constrained from acting value-rationally to consider and then take action on questions about the moral content of TIF projects. Nonetheless, planning staff developed an instrumentally-rational planning and policy exercise, which they performed as a way to channel their value-rational concerns about the assumption that every economic development project is an unambiguously valuable goal. 相似文献

Landscape values are a type of place value and are identified and mapped using public participation GIS (PPGIS). PPGIS engages nonexperts to identify important spatial information for environmental or natural resource planning. In 1998, we used PPGIS to identify landscape values for the Chugach National Forest (Alaska) plan revision process. In 2012, we conducted a longitudinal study of the same national forest using Internet PPGIS to identify changes in landscape values. The empirical results indicate stability in landscape values both in importance and spatial distribution. However, the use of different PPGIS methods (paper map vs. Internet) in the longitudinal study also introduced challenges in interpreting and explaining the spatial results. We discuss trade-offs in conducting longitudinal PPGIS research using mixed methods. PPGIS appears well suited for public lands planning, and national forest planning in particular, but barriers to use, such as regulatory approval, remain formidable. 相似文献

This paper tracks the changing role of public participation in planning thought. In doing so, the paper shows that the role of public participation in planning is largely determined by the nature of the planning enterprise being undertaken. The definition of the planning problem, the kinds of knowledge used in planning practice, and the conceptualisation of the planning and decision-making context are the important determinants of the extent of participation offered to the public. The paper therefore contributes to thinking about how to evaluate public participation by showing that it can only be understood in terms of the decision-making context in which it is embedded. Specifically, it makes little sense to evaluate public participation in terms that are not shared by the planning model itself 相似文献

Public participatory geographic information systems (PPGIS) have been advanced as a means to include those who have been traditionally excluded from numerous place-specific governance activities, including planning and policymaking and as a way to resolve some of the long-standing tensions between critical traditions in human geography and the ever-expanding field of GIS. Despite the rapid adoption of participatory GIS by academics, government officials, and planning professionals, there are few guidelines of best practices for PPGIS researchers and practitioners to draw on and little effort has been made to understand how and in what ways PPGIS efforts are (or perhaps are not) effective. This article contributes to these important debates by evaluating the geography of participation in a recent participatory planning project undertaken in Muncie, Indiana. Using the mapped information that was generated from a series of public meetings, we have identified the presence of significant spatial bias in the process of participation that affected the resulting plan. This was an unexamined source of bias during this process and an example of why any emerging conversations about the best practices for PPGIS must include a consideration of the geography of participation. 相似文献

This research presents an intelligent planning support system based on multi-agent systems for spatial urban land use planning. The proposed system consists of two main phases: a pre-negotiation phase and an automated negotiation phase. The pre-negotiation phase involves interaction between human actors and intelligent software agents in order to elicit the actors’ social preferences. The agents employ social value orientation theory, which is rooted in social psychology, in order to model actors’ social preferences. The automated negotiation phase involves negotiation among autonomous software agents, the aim being to achieve consensus about the spatial problem on behalf of the relevant actors and using the information obtained.
This study employs a computationally effective Bayesian learning technique, along with social value orientation theory, to design socially rational intelligent agents who work on behalf of real actors. The proposed system is applied to a real world urban land use planning case study. Human actors participate in a pre-negotiation phase, and their social preferences are elicited by intelligent software agents through a number of interactions. Then, software agents come together to engage in an automated negotiation phase and eventually reach an agreement on the spatial configuration of urban land uses on behalf of the actors. The results of the study show that the proposed system is effective at performing an automated negotiation, plus that the final plan – which is the output of the automated negotiation – produces higher social utility and better spatial land use configurations for the agents. 相似文献

Forest parks provide important recreational and tourism bene?ts to residents, so it is essential to know what residents’ perceptions are regarding the recreational value of forest parks for participatory forest planning and management. This study investigated forest park recreational value in the physical, psychological, and social dimensions in Shanghai according to questionnaires completed by 658 respondents, and examined the relationships between recreational value and residents’ social variables by multiple correspondence analysis (MCA). The results show the following: 1) The recreational value of forest parks is perceived as most important in the psychological dimension, while in the social dimension it is appreciated the least. 2) In terms of the differences in forest park recreational value in suburbs and rural areas, the social value in rural areas had significantly higher scores than in the suburbs, and the psychological value in suburbs is much higher than that in the rural areas. 3) Regarding the social variables which characterize residents in suburbs and rural areas, females and younger groups tended to assign higher scores to recreational value than males and older groups. Moreover, citizens with low education or low income also assigned higher scores to recreational value compared to more educated or higher-income residents. The results of this study reveal the recreational value characteristics of Shanghai forest parks in the three dimensions, which can provide a scientific basis for the sustainable development of urban forest resources and contribute to reasonable planning and management. 相似文献
