We use the SSTL (Singwi, Sjölander, Tosi, Land) approximation to investigate the short–range correlations in a one dimensional electron gas, for the first time. Although SSTL is introduced to better satisfy the compressibility sum rule in three dimensions, we show that the widely used STLS (Singwi, Tosi, Land, Sjölander) approximation is more successful in the case of the one dimensional electr...

introduction land use and land cover change (lucc) is a complex issue resulted from biophysical, socio-economic, cultural, organizational and technological factors in different spatial and temporal scales. lucc considered as an important threat to biodiversity as causing the fragmentation, natural vegetation destruction and natural areas isolation the regions which managed by environmental prot...

Cadastres are a core component of land administration systems and an important infrastructure which facilitates the implementation of land use policies. While most cadastral systems traditionally have a primary objective of supporting the operation of land markets, they increasingly play a key role in a broader land administration infrastructure which supports economic development, environmenta...

The effect of land fragmentation on agriculture has worried policymakers for a long time because it is expected to be a negative effect. Land consolidation policies are frequently implemented to soften the degree of land fragmentation. However, to the authors' knowledge, no study in the dairy sector has empirically analyzed the role of land fragmentation on farm productivity and profits. This s...

Land use for animal production influences the earth system in a variety of ways, including local-scale modification to biodiversity, soils, and nutrient cycling; regional changes in albedo and hydrology; and global-scale changes in greenhouse gas and aerosol concentrations. Pasture is furthermore the single most extensive form of land cover, currently comprising about 22-26% of the earth's ice-...

Scientific understanding of the global carbon cycle is required for developing national and international policy to mitigate fossil fuel CO2 emissions by managing terrestrial carbon uptake. Toward that understanding and as a contribution to the REgional Carbon Cycle Assessment and Processes (RECCAP) project, this paper provides a synthesis of net land–atmosphere CO2 exchange for North America (...

Information about land cover and land use is needed for a wide range of applications such as nature protection and biodiversity, forest and water management, urban and transport planning, natural hazard prevention and mitigation, monitoring of agricultural policies and economic land use modelling. A number of different remotely-sensed global land cover products are available but studies have sh...
