| Information about the land cover of a region it is a key information for several purposes. This paper aimed to elaborate land-cover maps using digital satellite images obtained in 1997 from seven watersheds (Piracicaba, Moji-Guaçu, Alto Paranapanema, Turvo Aguapeí, Peixe, and São José dos Dourados) located in the State of São Paulo, southeastern Brazil. Additionaly, this study evaluated the relationship between land-cover and slopes of the terrain of the seven watersheds. A third objective was to estimate the percentage of riparian vegetation currently remaining along the streams in a 30-meter width buffer zone. Three research questions were posed: i) What is the dominant land-cover of these watersheds? ii) Is the riparian vegetation well preserved in the... |

| Green manure is a soil management technique which provides several benefits to agroecosystems, improving the chemical, physical and biological quality of the soil, allowing them to provide different ecosystem services. Thus, the purpose of this work was to select green manures to compose multifunctional agroecosystems that provide ecosystem services in a semi-arid environment through the addition of biomass, C and N, and nutrient cycling. Thus, 29 treatments were evaluated in two cultivation cycles, using 14 species of legumes, oilseeds and grasses, distributed in single and intercropped crops. The green manures were cut at 70 days after sowing, and samples of the shoot and root parts were collected, with the production of fresh and dry biomass and the N,... |

| Resumo. A Bacia do Alto Paraguai (BAP) tem grande importância ecológica para o Brasil, uma vez que abriga o Pantanal, uma das maiores planícies inundáveis do mundo. O monitoramento do uso e cobertura da terra é estratégico não só na planície da BAP como também em seu planalto, uma vez que as cheias do Pantanal são influenciadas pelo seu entorno. Parte do território da BAP na porção mato-grossense é contemplada pelos mapeamentos do Projeto TerraClass e, desta forma, a dinâmica de uso e cobertura da terra nessas localidades pode ser avaliada por meio desses dados oficiais. O objetivo deste estudo foi analisar a dinâmica do uso e cobertura da terra em dois municípios do estado de Mato Grosso a partir das ferramentas geoespaciais disponibilizadas por um... |

| Abstract: Expansion of agriculture in the Brazilian Amazon has been driven not just by demands from traditional, rural producers, but also large agriculture and cattle producers, both of whom have put considerable pressure on remaining forests and their watersheds. Monitoring of these watersheds has been a focus of intensive study for the past 20 years and although this work has greatly increased our understanding, considerable gaps still remain in our ability to provide adequate recommendations for land management and associated public policies. In this study we present a summary of findings from these previous results. For small properties, the use of fire to prepare land for cultivation remains controversial, while in large properties, forest conversion... |

| Contemporary food production is facing many challenges. One of these challenges is to re-connect the food system with various public domains, such as spatial planning. Sustainable food planning is a growing domain in planning research. One of the important topics of research concerns the geographical or territorial properties of the food system. This paper addresses the territorial properties of the agricultural system using different spatial concepts. The paper includes a case study of a greenhouse vegetable production system in Venlo, the Netherlands, and its relationships with the regional spatial organization. The assessment allowed to draw some conclusions on the suitability of different spatial concepts to assess the spatial organization of food... |

| 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.... |

| Recent mandates in the United States require federal agencies to incorporate climate change science into land management planning efforts. These mandates target possible adaptation and mitigation strategies. However, the degree to which climate change is actively being considered in agency planning and management decisions is largely unknown. We explored the usefulness of climate change science for federal resource managers, focusing on the efficacy of potential adaptation strategies and barriers limiting the use of climate change science in adaptation efforts. Our study was conducted in the northern Rocky Mountains region of the western United States, where we interacted with 77 U.S. Forest Service and Bureau of Land Management personnel through... |

| 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... |
