Detailed land cover information is valuable for mapping complex urban environments. Recent enhancements to satellite sensor technology promise fit-for-purpose data, particularly when processed using contemporary classification approaches. We evaluate this promise by comparing the influence of spatial resolution, spectral band set and classification approach for mapping detailed urban land cover...

Resolution of the input GIS data used to parameterize distributed-parameter hydrologic/water quality models may affect uncertainty in model outputs and impact the subsequent application of model results in watershed management. In this study we evaluated the impact of varying spatial resolutions of DEM, land use, and soil data (30 x 30 m, 100 x 100 m, 150 x 150 m, 200 x 200 m, 300 x 300 m, 500 ...

Rural housing land accounted for 67.3% of China’s total construction land in 2000. While there are numerous studies analyzing the loss of arable land due to urban sprawl, less attention has been paid to the study of rural housing land in China. This paper develops a theoretical framework for rural housing land transition in China. It introduces a research method, which is using the spatial diff...

The transport characteristics of phosphorus in soil and the assessment of its environmental risk have become hot topics in the environmental and agricultural fields. The Sanjiang Plain is an important grain production base in China, and it is characterised by serious land use change caused by large-scale agricultural exploitation. Agricultural inputs and tillage management have destroyed the so...

Cellular Landscapes. Many ABM/LUCC researchers begin by developing models that operate over an abstract landscape, even when their longer-term goals include application to real-world landscapes. Roles for abstract ABM/LUCC models are discussed by Parker and colleagues (Parker, Berger, and Manson 2002 a,b; Parker, Manson, and Berger 2002; Parker et al. 2003), and the advantages of a progression ...

The study first identified fully efficient farmers and then estimated technical efficiency of inefficient farmers, identifying their determinants by applying a Zero Inefficiency Stochastic Frontier Model (ZISFM) on a sample of 300 rice farmers from central-northern Thailand. Next, the study developed scenarios of potential production increase and resource conservation if technical inefficiency ...
