There is considerable controversy over whether pre-Columbian (pre-A.D. 1492) Amazonia was largely "pristine" and sparsely populated by slash-and-burn agriculturists, or instead a densely populated, domesticated landscape, heavily altered by extensive deforestation and anthropogenic burning. The discovery of hundreds of large geometric earthworks beneath intact rainforest across southern Amazoni...

This paper reviews an analysis of land use change impacts of expanded biofuel production with GTAP-BIO computable general equilibrium (CGE) model. It describes the treatment of energy substitution, the role of biofuel by-products, specification of bilateral trade, the determination of land cover changes in response to increased biofuel feedstock production, and changes in crop yields – both at ...

Global change poses significant challenges for ecosystem conservation. At regional scales, climate change may lead to extensive shifts in species distributions and widespread extirpations or extinctions. At landscape scales, land use and invasive species disrupt ecosystem function and reduce species richness. However, a lack of spatially explicit models of risk to ecosystems makes it difficult ...

Plant invasions and their impact on land use pose difficult research questions, due to the complex relationships between the ecological nature of the invasion and the human responses to the invasion. This paper focuses on the linkages between an invasion of bracken fern and land use decisions in an agricultural frontier in southern Mexico. Agriculture in this region is practiced on an extensive...

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...

extensive flood damages all over the world necessitate its control and operation. hydrologic impacts of land use change appear in many ways such as total runoff, and flood peak flow. this study was performed in 2014 and aimed to investigate the impacts of land use changes on the occurrence of floods in the catchment of boostan dam in golestan province, iran. for this purpose, watershed modeling...

Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict ...

Urbanization brings biophysical changes in the composition of the landscape. Such change has an impact on the thermal environment locally. The urban mosaic of land use and land cover is thus characteristically composed of local climate zones. The spatial variation in the land surface temperature across specific zone is studied for Bhopal city. The objective of the study was to understand how th...

land-use spatial allocation is a multi-objective collaborative spatial optimization methodfor rational use of the land use. based on global search capabilities and the information feedbackmechanism of ant colony optimization (aco), a land-use spatial allocation model (aco-la) isproposed. firstlyfirst, a construction graph is built for modeling the land-use spatial allocationproblem. secondlysec...
