Lenore Fahrig,* Jacques Baudry, Lluı́s Brotons, Françoise G. Burel, Thomas O. Crist, Robert J. Fuller, Clelia Sirami, Gavin M. Siriwardena and Jean-Louis Martin Abstract Biodiversity in agricultural landscapes can be increased with conversion of some production lands into morenatural – unmanaged or extensively managed – lands. However, it remains unknown to what extent biodiversity can be enhanc...

The Upper Yangtze River Basin comprises a densely-populated agricultural region with mountainous and hilly landforms. Intensive cultivation has been extended onto steep hillslopes, which constitute the principal source area for sediment production. Soil conservation on sloping arable lands is thus of utmost priority for persisting sustainable agricultural production and maintaining sound ecosys...

Although biofuels are thought to be one of the solutions for reducing carbon dioxide in the atmosphere, the net effects might be ambiguous when indirect land use effects are incorporated. Along with the increasing price of biofuel crops, forest lands might be destroyed throughout the world. In this study, the net effect of the increases in U.S. production of corn due to ethanol demand is explor...

Agricultural beneficial management practices (BMPs) are popular strategies for mitigating non-point sources of pollution. There are economic costs for BMP placement on agricultural lands mainly because it affects profit margins of farm operations. Given the cost implication and biophysical heterogeneity of farm lands, 8 the spatial targeting of BMP placement is consequential to their cost-effec...

Agricultural lands, like other categories of land, perform an ecological function as the main object nature and habitat man all living plant organisms, well economic real estate means production in agriculture. In order to protect landowners users are obliged take measures: restore fertility agricultural land; lands from water wind erosion, mudslides, flooding, waterlogging, secondary salinizat...

Agricultural soil loss and deposition in aquatic ecosystems is a problem that impairs water quality worldwide and is costly to agriculture and food supplies. In the US, for example, billions of dollars have subsidized soil and water conservation practices in agricultural landscapes over the past decades. We used paleolimnological methods to reconstruct trends in sedimentation related to human-i...

extended abstract 1. introduction nowadays, one of the challenging issues of agriculture is the ownership problem and impact of the inheritance system on its procedure, performance and productivity. dividing agricultural lands between heirs led to fragmentation and smallness of the lands and emerging problems such as loss of agricultural water, lack of efficient use of agricultural machinery, r...
