| We present a new method for ecologically sustainable land use planning within multiple land use schemes. Our aims were (1) to develop a method that can be used to locate important areas based on their ecological values; (2) to evaluate the quality, quantity, availability, and usability of existing ecological data sets; and (3) to demonstrate the use of the method in Eastern Finland, where there are requirements for the simultaneous development of nature conservation, tourism, and recreation. We compiled all available ecological data sets from the study area, complemented the missing data using habitat suitability modeling, calculated the total ecological score (TES) for each 1 ha grid cell in the study area, and finally, demonstrated the use of TES in... |

| Neste trabalho, avaliou-se a aptidão agrícola das terras dos reassentamentos rurais da usina hidrelétrica de Manso, com o objetivo de fornecer subsídios para o planejamento de uso e manejo dos solos e a proposição de estratégias de manejo que assegurem o uso sustentável das terras de pequenas propriedades rurais inseridas em áreas de ecossistemas frágeis. A avaliação da aptidão agrícola das terras resultou da interpretação das características dos solos, das necessidades das culturas e dos níveis de manejo A, B e C. Nessa avaliação, as unidades de mapeamento de solos foram enquadradas nas seguintes classes de aptidão: boa, regular, com restrição ou inapta, conforme os níveis de manejo A (baixo nível tecnológico), B (médio nível tecnológico) e C (alto nível... |

| The patchwork of government influences that shape the protection and management of construction mineral resources--sand, gravel, and crushed stone--includes statutes, regulations, guidance documents, and court decisions at the federal, state, and local level. Across the Washington-Baltimore metropolitan area, both these influences and the experiences that the counties have had in managing construction mineral resources range widely. Our principal objective in this study is to discuss the mechanisms that counties use to manage such resources; the level and source of concern that local residents have with respect to construction mineral extraction operations; officials' perceptions about trends in the supply and demand for mineral resources; and the level of... |

| Although the criteria for defining erosion tolerance are well established, the limits generally used are not consistent with natural, economical and technological conditions. Rates greater than soil formation can be accepted only until a minimum of soil depth is reached, provided that they are not associated with environmental hazard or productivity losses. A sequence of equations is presented to calculate erosion tolerance rates through time. The selection of equation parameters permits the definition of erosion tolerance rates in agreement with environmental, social and technical needs. The soil depth change that is related to irreversible soil degradation can be calculated. The definition of soil erosion tolerance according to these equations can be... |

| ABSTRACT: Increasingly, applications of machine learning techniques for digital soil mapping (DSM) are being used for different soil mapping purposes. Considering the variety of models available, it is important to know their performance in relation to soil data and environmental variables involved in soil mapping. This paper investigated the performance of eight machine learning algorithms for soil mapping in a tropical mountainous area of an official rural settlement in the Zona da Mata region in Brazil. Morphometric maps generated from a digital elevation model, together with Landsat-8 satellite imagery, and climatic maps, were among the set of covariates to be selected by the Recursive Feature Elimination algorithm to predict soil types using machine... |

| 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... |

| Erosion tolerance is the most multidisciplinary field of soil erosion research. Scientists have shown lack in ability to adequately analyze the huge list of variables that influence soil loss tolerance definitions. For these the perspectives of erosion made by farmers, environmentalists, society and politicians have to be considered simultaneously. Partial and biased definitions of erosion tolerance may explain not only the polemic nature of the currently suggested values but also, in part, the nonadoption of the desired levels of erosion control. To move towards a solution, considerable changes would have to occur on how this topic is investigated, especially among scientists, who would have to change methods and strategies and extend the perspective of... |

| Land use and crop production in the Khorezm region in western Uzbekistan, exemplarily for the irrigated low-lands of Central Asia, is adversely affected by the excessive, non-sustainable use of irrigation water on one hand, repeated droughts on the other hand, and by soil degradation by secondary salinization. One of the research objectives of the German-Uzbek Khorezm project, funded by the German Ministry for Education and Research (BMBF) and led by ZEF, is to better understand options for land use and choice of technology at the farm level in order to evaluate and propose technological alternatives and policy options for sustainable land use in Khorezm. To address the latter, the integrated so-called Farm-Level Economic-Ecological Optimization Model... |

| The plant-available water capacity of the soil is defined as the water content between field capacity and wilting point, and has wide practical application in planning the land use. In a representative profile of the Cerrado Oxisol, methods for estimating the wilting point were studied and compared, using a WP4-T psychrometer and Richards chamber for undisturbed and disturbed samples. In addition, the field capacity was estimated by the water content at 6, 10, 33 kPa and by the inflection point of the water retention curve, calculated by the van Genuchten and cubic polynomial models. We found that the field capacity moisture determined at the inflection point was higher than by the other methods, and that even at the inflection point the estimates... |
