Agricultural Land Use and the Eastern Cottontail in Illinois
… index for cottontail abundance was related to 13 agricultural land use variables for 1956-69 and 1982-89, using logistic regression and CART (classification and regression trees) models.

Empirical Relationships between Water Quality and Agricultural Land Use in Rural Maine
… eutrophication of freshwater lakes due to land use change is a growing global problem with economic consequences, such as a reduction in shoreline property value. Managing eutrophication is of utmost importance in Maine, USA due to the large number of inland fresh waterbodies and their …

Defining agricultural land use in Rondonia, Brazil by examination of spot multispectral data
A number of tests were conducted to determine the realizable accuracies of the Global Positioning System for natural resource conditions. The effects of terrain, forest canopy, number of consecutive position fixes, and PDOP on accuracy were evaluated. Position accuracies were determined for a total …

The Geomorphic Influence of Agricultural Land Use on Stream Hydraulics and Biological Function
Agricultural land use near streams frequently results in long-term disturbance to woody riparian vegetation and an alteration of reach scale geomorphic structure. Such disturbances often result in increased fine sediment input to the stream along with direct changes in channel structure. The study …

Changes in agricultural land use in Darke and Mercer counties, Ohio, from 1920-1964
… chosen for the examination of local data because of their predominantly agricultural orientation.

Effects of Perturbations by Agricultural Land Use on Structure and Function of Stream Ecosystems
The effects of agricultural land use on headwater stream ecosystems were assessed. Three factors were examined: (1) the role of physical and biological processes in terrestrial, riparian, and aquatic portions of agricultural watersheds as regulators of water quality, (2) the changes in fish c

War and Agriculture: Three Decades of Agricultural Land Use and Land Cover Change in Iraq
… a result of war and sanctions. The first study used MODIS NDVI data during OIF and the end of UN sanctions to study changes in cultivated area for Iraq as a whole and to identify spatial patterns. The results revealed significant changes in cultivated area for Iraq as a whole, with cultivated …

Influence of Agricultural Land Use on Allochthonous Input and Leaf Breakdown in Southern Appalachian Streams
… removal of riparian vegetation associated with agricultural land use affects stream ecosystem structure and function. The objectives of this study were to measure and compare allochthonous input and leaf breakdown rates along a gradient of agricultural land use in southern Appalachian streams. …

Water Quality Impacts from Agricultural Land-Use in the Karst Groundwater Basin of Qingmuguan, Chongqing, China
… should be given to water quality impacts from land-use practices near conduit inputs. The climate which affects a certain karst area can also have different impacts on water resources considerations. For example, in the temperate climate of Kentucky precipitation is essentially even in …

Estimating hydrologic fluxes, crop water use, and agricultural land use in China from multiple data sources
… altered the terrestrial environment by changing land use (Ramankutty et al., 2008) and by altering the water cycle through both co-opting rainfall and surface water withdrawals (Postel et al., 1996). As the world's population continues to grow and individual diets become more resource-intensive, …

Influence of riparian forest and agricultural land use on community structure and ecosystem function in headwater streams
… stream water quality and instream habitat in agricultural areas because the vegetation can filter runoff, reduce bank erosion, and restore channel morphology. However, previous studies have found that protecting narrow strips of riparian areas, typically 30-50 meters wide along streams, may be …

Evaluation of irrigation water demand and agricultural land use in relation to surface water availability in Chongwe catchment.
… growth has been characterised by an increase in agricultural irrigation activities, competitiveness in water use which have caused water stress and conflicts in some catchments. Some water availability assessment works in Chongwe Catchment have been done by various researchers but very little …

Agrobiodiversity enhancement for the sustainability of the tropical uplands: An evaluation of agricultural land use in Liliw, Laguna, Philippines
… environmental degradation without losing agricultural productivity. However, there is not yet sufficient evidence to support the important role that ABDE might have for managing agricultural land use in the tropical uplands. This research is an attempt to help fill this knowledge gap. The …

Economic growth and land use change: implications for global biodiversity.
This study examines whether land use change and biodiversity loss conform to an environmental Kuznets curve, a relationship in which certain environmental impacts increase then decrease with economic growth. The study draws on the experience of economic structural change to show that agricultural …
