One of the most important problems facing desert areas today is the growing trend of desertification and land use change. Land use is a special use of man from the earth. These uses are changing over time and these changes lead to increased land degradation and ecosystem destruction, especially in arid and semi-arid regions. Accordingly, in this research, the trend of land use change in the eas...
This paper discusses recent developments in the market for agricultural land in Slovakia related to the new law on land acquisition. The stated objective of this law is to protect agricultural land from non-agricultural use. We analyze landrelated data as reported by sellers in the newly established Registry of offers of agricultural land administered by the Ministry of Agriculture and Rural De...
large scale land use/cover changes and habitat fragmentation is a major factor in the distribution and functioning of ecosystems. for analysis the relationship between land use changes and their impacts on biodiversity, land cover and land use information is needed at different scales. the main goal of this study was to quantify the land use/ cover changes in arasbaran biosphere reserve, northw...
Agricultural Census data is summarised over spatially course reporting units for reasons of farm confidentiality. This is problematic for research at a local level. This paper describes an approach combining dasymetric and volume preserving techniques to create a national land use dataset at 1km resolution. The results for an English county are compared with contemporaneous aggregated habitat d...
The Mid-eastern Inner Mongolia of China, a typical agro-pastoral transitional zone, has undergone rapid agricultural land use changes including land reclamation and cropland abandonment in past decades due to growing population and food demand, climatic variability, and land use policy such as the "Grain for Green" Project (GFG Project). It is significant to the regional ecology and sustainabil...
The presence of Damghan Erg in West of Damghan Playa indicates high wind activity in this desert region. Due to technological advances and population growth in recent decades, large parts of past land uses have changed. These changes can exacerbate wind erosion and affect lands sedimentation. In this study, first, the land use maps of years 1974 and 2003 were prepared. The comparison of these m...
Although the Netherlands is one of the most densely populated countries, two thirds of the land area are still under agricultural use. Major socio-economic changes are however expected for the agricultural sector. The increasing globalisation of economic relations in agriculture and the possible reduction of European price support to farmers are examples of such developments that may affect agr...
Growing global population figures and per-capita incomes imply an increase in food demand and pressure to expand agricultural land. Agricultural expansion into natural ecosystems affects biodiversity and leads to substantial carbon dioxide emissions. Considerable attention has been paid to prospects for increasing food availability, and limiting agricultural expansion, through higher yields on ...
Biofuel policies (blend mandate or tax credit) have impacts on food and energy prices, and on land-use. The magnitude of these effects depends on the market response to price, and thus on the agricultural supply curve, which, in turn, depends on the land availability (quantity and agronomic quality) and relative prices. To understand these relationships, we develop a theoretical framework with ...
