| Benefit transfer has been an important, practical policy tool appealing to government agencies, especially when time or budget is constrained. However, the existing literature fails to support convergent validity of benefit transfer using the stated-preference method. This empirical study examines the convergent validity of benefit transfer using the choice modeling method, a potentially promising technique compatible with the heterogeneity of the transfer contexts. Based on a survey designed for Rhode Island (RI) and modified only slightly for Massachusetts (MA), regarding coastal land management, four convergent validity tests were conducted on the benefit transfer from RI to MA. Although results fail to support convergent validity in all aspects, the... |

| RESUMO. O estado de Mato Grosso passou por um rápido processo de conversão da cobertura vegetal nas últimas décadas, ainda pouco estudado. O Projeto TerraClass tem sido responsável pelo mapeamento do uso e cobertura da terra na porção desflorestada da Amazônia Legal. Neste contexto, o objetivo do trabalho foi analisar as mudanças do uso e cobertura da terra no estado de Mato Grosso por meio do GeoPortal TerraClass, de 2004 a 2014. A classe temática que mais ganhou espaço foi a Cultura Agrícola Temporária, com 22.714,67 km², representando um crescimento de 151,08%, ocupando principalmente áreas da classe temática Pastagem Cultivada Herbácea, evidenciando o processo de transição do sistema de produção da pecuária para o sistema de produção agrícola no... |

| O objetivo do trabalho foi aplicar uma metodologia para estimar áreas propensas a vulnerabilidade ambiental na região serrana do estado do Rio de Janeiro, utilizando análise multicritério e modelagem em (SIG), através da álgebra de mapas. Os procedimentos utilizados envolveram a aquisição, conversão, armazenamento digital de dados básicos de solo, litologia, relevo, declive, uso da terra, vegetação e pluviosidade, confecção de base de dados, modelo digital de elevação e superposição temática em SIG, com base na interação, ponderação e atribuição de valores específicos a cada fator condicionante da vulnerabilidade, segundo a sua importância. Assim, cada fator foi ponderado do menos vulnerável (1), para o mais vulnerável (5). O mapa final resultante... |

| Two research projects were established to foster Brazilian-German collaboration and inter- and transdisciplinary research in the southern Amazon region. In the scope of the German BMBF-FONA program (Federal Ministry for Education and Research?Research for Sustainable Development), the Carbiocial consortium (www.carbiocial.de) investigated C stock changes, greenhouse gas (GHG) emissions, erosion, catchment hydrology, agricultural production, land cover, socio-economic drivers, policy impact and actor networks using experiments, monitoring, surveys, remote sensing and dynamic simulation modelling. In Brazil, the corresponding research project Carbioma focused more specifically on the political programs which were established to mitigate environmental... |

| What is social structure, and how does it influence the views and behaviors of land managers? In this paper, we unpack the term "social structure" in the context of current research on institutions, social networks, and their role(s) in resource management. We identify two different kinds of structure, formal and informal, and explore how these link to views of land management and management practice. Formal structures refer to intentionally designed organizations that arise out of larger institutional arrangements; informal ones refer to social networks, based on the communication contacts individuals possess. Our findings show significant correlations between respondents' views regarding land management and their social networks; it is these informal... |

| European ("scientific") and Aboriginal ("experiential") perspectives on fire management in northern Australia are often contrasted with each other. For Europeans, management is portrayed as a science-based, strategically directed and goal-oriented exercise aimed at achieving specific ecological outcomes. In contrast, landscape burning by Aboriginal people is more of an emergent property, diffusely arising from many uses of fire that serve social, cultural, and spiritual, as well as ecological, needs. Aboriginal knowledge is acquired through tradition and personal experience, rather than through the scientific paradigm of hypothesis testing. Here I argue that, in practice, science plays only a marginal role in European fire management in northern Australia.... |

| This study investigates the micro-determinants of land use change using community, household and plot histories, an ethnographic method that constructs panel data from systematic oral recalls. A 20-year historical timeline (1975-1995) is constructed for the village of La Lima in central Honduras, based on a random sample of 97 plots. Changes in land use are examined using transition analysis and multinomial logit analysis. Transition analysis shows that land use transitions were relatively infrequent in areas under extensive cultivation, but more so in areas of intensive cultivation; and that most changes favored intensification. Econometric analysis suggests that land use intensification was influenced by plot level variables (especially altitude, slope,... |

| This paper investigates the patterns and determinants of change in livelihood strategies (“development pathways”), land management practices, agricultural productivity, resource and human welfare conditions in Uganda since 1990, based upon a community-level survey conducted in 107 villages. The pattern of agricultural development since 1990 involved increasing specialization and commercialization of economic activities, consistent with local comparative advantages and market liberalization. This pattern was associated with changes in land use and agricultural practices, including expansion of cultivated area, grazing lands and woodlots at the expense of forest and wetlands; increased ownership of cattle but declining ownership of other livestock; and... |
