Integrating remote sensing (RS) with geographic information system (GIS), distribution digital maps of land desertification, spatial database and their statistics in the year of 1986, 1993 and 2000 were obtained by correcting, amplifying and auto classifying the RS images of interlaced zone for agriculture and animal husbandry in northern Shaanxi. The results showed that in the last 15 years de...

We describe a project that is monitoring land condition in the south west of Western Australia using Landsat Thematric Mapper satellite images and terrain data derived from digital elevation models (DEMs). Land Monitor is a multi-agency project of the Western Australian Salinity Action Plan supported by the Natural Heritage Trust. The focus of the project is on broad-scale monitoring of land co...

Traditionally, urban analysis has been quick to adopt and benefit from developments in technology (e.g., microcomputer, GIS) and techniques (e.g., statistics, mathematical programming). This has not been the case, however, with newer methods of spatial analysis – in particular, spatial statistics. Only recently has this situation started to change. This paper documents the confluence of spatial...

Local changes in land use result from the decisions and actions of land-users within land systems, which are structured by local and global environmental, economic, political, and cultural contexts. Such cross-scale causation presents a major challenge for developing a general understanding of how local decision-making shapes land-use changes at the global scale. This paper implements a general...

In urban and rural areas under rapid urbanization, a proper understanding of the relationship between population and construction land use is important for regional sustainable development. The decoupling method is a particularly useful way to examine this relationship. However, the decoupling method only considers the current relationship between population and construction land, ignoring the ...

The study aims an investigating for the implication of tree based land use pattern to smallholder farmers’ food insecurity coping mechanism. Information on household characteristics, purpose of land use practices, household food security situation and tree based land use has contributed to household food security were collected through household interviews. About 11% of the total households wer...

land use is often referred as the basis for urban planning. perhaps the main reason is that the discussion of fundamental related to urban planning objectives has play the first role in the land use studies. basic topics such as proper location, optimal allocation, diversification, functionality and … which are in direct contact with comfort goals, are the last objectives of urban planners and ...

This paper analyses the effect of spatial input data resolution on the simulated water balances and flow components using the multi-scale hydrological model TOPLATS. A data set of 25 m resolution of the central German Dill catchment (693 km2) is used for investigation. After an aggregation of digital elevation model, soil map and land use classification to 50 m, 75 m, 100 m, 150 m, 200 m, 300 m...
