Although assistance to farming remains the dominant method for supporting the rural sector in the UK, there has been a shift in policy towards agri-environmental schemes which attempt to reconcile competing demands on the countryside as a simultaneous provider of food, rural livelihoods and environmental goods and services. Many of these issues and challenges facing UK and European agriculture ...

Phosphorus losses from arable land need to be reduced to prevent eutrophication of surrounding waters. Owing to the high spatial variability of P losses, cost-effective countermeasures need to target parts of the catchment that are most susceptible to P losses. Field surveys identified critical source areas for overland flow and erosion amounting to only 0.4-2.6 % of total arable land in four d...

Accurate mapping of temporal changes in urban land use and land cover (LULC) is important for monitoring urban expansion and changes in LULC, urban planning, environmental management, and environmental modeling. In this study, we present a feature-based approach of the decision tree classification (FBA-DTC) method for mapping LULC based on spectral and topographic information. Landsat 5 TM and ...

Land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. Decreasing of forest area in the North of Iran is one of the critical problems in recent years. The aims of this study are to detect land use changes between 1967 to 2002 using satellite images of Land Sat 7 ETM (2002), aerial photos and digital topog...

< p>Successful implementation of land reform requires the implementation of large-scale market transformations, in particular in the structure of land tenure and land use, in the field of land valuation. The article is devoted to the development of scientific and methodological bases of economic evaluation and use of land resources of agricultural enterprises, substantiation of approaches and r...

Despite the apparent abundance of land, agricultural land with a dependable growing period represents a fraction of the total land area in Ethiopia. Moreover, land degradation is extensive and severe, particularly in the highlands above 1500 meters above sea level, which account for about 40 percent of the total land area but home for 90 percent of the total population and 70 percent of livesto...
