The impact of land use on the global carbon cycle and climate is assessed. The Bern carbon cycle-climate model was used with land use maps from HYDE3.0 for 1700 to 2000 A.D. and from post-SRES scenarios for this century. Cropland and pasture expansion each cause about half of the simulated net carbon emissions of 188 Gt C over the industrial period and 1.1 Gt C yr−1 in the 1990s, implying a res...

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 ...

Conventionally, land use and transport interaction is studied through computer simulation using large-scale integrated land use and transport models. Though comprehensive, most of these models fail to recognise that urban growth is not entirely a global but also a local process. The over-complex and data hungry nature of these models further render them inefficient as tools for strategic planni...

planners have regarded understanding urban use per capita since the beginning of new thinking of urban development. this was stared with its pragmatics toward primary comprehensive urban plans and became a source for urban development plans that have tried to adapt per capita and standards with country’s conditions. iran's supreme council for planning and architecture, determined standards...

soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure.so, this research has been done for achieving this purpose. this area is arounding sa...

land use planning, refers to how to use, distribute and protect the land. this type of planning can be considered from different perspectives, such as sustainable development perspective view is one of important land use views. in this paper we have tried to study and evaluate the land use change of maragheh city from sustainable development perspective, and study the harmony or disharmony with...

Understanding the processes of historical land-use change is crucial to the research of global environmental sustainability. Here we examine and attempt to disentangle the evolutionary interactions between land-use change and its underlying causes through a historical lens. We compiled and synthesized historical land-use change and various biophysical, political, socioeconomic, and technical da...

land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. so far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. this paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...

many investigations have demonstrated that arid regions display ideal conditions for remote sensing applications such as, land cover/land use detection. the aim of this study was to evaluate the capability of thematic mapper (tm) thermal band in land cover/land use mapping in the ardakan region of yazd province, an area of desert with severe salinity conditions, and the mook region in the f...
