Improper land use is one major cause of non-point source pollution. Integrated modeling would support the evaluation and optimization of land use for the non-point source pollution control. In this study, the CLUE-S (the Conversion of Land Use and its Effect at Small regional extent) and SWAT (Soil and Water Assessment Tool) models were coupled to simulate pollution loads under different land u...

road network (rn) can affect patterns and distribution of land uses and covers. road network expansion has both direct and indirect impacts on land uses and covers changes. agricultural land conversions (alcs) are especially known as one of the main important types of land use changes. the purpose of this paper, in addition to estimation of the direct impact of rn expansion on alcs, is to evalu...

Extensive land and market reform in Vietnam has resulted in dramatic increases in rice output over the past thirty years. The land and market reforms in agriculture were pervasive, moving the system of rice production from commune-based public ownership and control to one with effective private property rights over land and farm assets, competitive domestic markets and individual decision makin...

Historical land use information is essential to understanding the impact of anthropogenic modification of land use/cover on the temporal dynamics of environmental and ecological issues. However, due to a lack of spatial explicitness, complete thematic details and the conversion types for historical land use changes, the majority of historical land use reconstructions do not sufficiently meet th...

Forests are under pressure from land use change due to anthropogenic activities. Land use change and harvest are the main disturbances of forest landscape changes. Few studies have focused on the relative contributions of different disturbances. In this study, we used the CA-Markov model, a land-use change model, coupled with a forest landscape model, LANDIS-II, to simulate dynamic change in Ta...

The conversion of natural habitats to farmland is a major driver of the global extinction crisis. Two strategies are promoted to mitigate the impacts of agricultural expansion on biodiversity: land sharing integrates wildlife-friendly habitats within farmland landscapes, and land sparing intensifies farming to allow the offset of natural reserves. A key question is which strategy would protect ...

Agricultural frontiers are hot spots for the most dramatic land cover change in the history of humankind: forest conversion to agriculture. They are also areas of unusually rapid population growth and acute poverty, with scant access to public services and infrastructure. Although a large body of literature explores the determinants of land cover change on the frontier, one issue that has been ...
