| This study investigates the impacts of rural poverty on farmers' land management decisions, crop production and incomes, based upon analysis of data from the 1999/2000 Uganda National Household Survey. We find that the impacts of rural poverty on land management, crop production and income depend upon the type of poverty (i.e., what asset or access factor is constrained) and the type of land management considered. Ugandan households that are poorer in terms of access to land use labor more intensively and are less likely to use several land management practices and inputs, though among households that do use non-labor inputs, land-poor households use many of these inputs more intensively. As a result, land-poor households obtain higher value of crop... |

| We investigate the impacts of coffee and cotton production on land management and land degradation in Uganda, based on a survey of 851 households and soil measurements in six major agro-ecological zones, using matching and multivariate regression methods. The impacts of cash crop production vary by agro-ecological zones and cropping system. In coffee producing zones, use of organic inputs is most common on plots growing coffee with other crops (mainly bananas), and least common on mono-cropped coffee. Both mono-cropped coffee and mixed coffee plots have lower soil erosion than other plots in coffee producing zones because of greater soil cover. Potassium depletion is much greater on mixed banana-coffee plots. In the cotton production zone, few land... |

| 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... |

| ABSTRACT Changes in land use management in agricultural areas can affect the biodiversity of spider families. This study aimed to evaluate spider diversity in different land use systems with capture by two sampling methods, and to identify soil properties that can modulate the occurrence of spiders. Five land use systems, representative of traditional agricultural areas, were evaluated in the west of Santa Catarina, Brazil, to establish a scale of land use intensity: native forest, eucalyptus reforestation areas, pastures, crop-livestock integration areas, and annual crops under no-tillage. The collection methods were manual from soil monoliths and soil traps. Altogether 479 individuals were captured, which were distributed among 20 families, 40 genera,... |

| 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... |

| 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... |
