The Yazd-Ardakan basin in Central Iran has two separated aquifers. The shallow unconfined aquifer is supplies 40 Qanats. The deep saturated confined aquifer is the main water storage. Due to over-withdrawal, water table has been decreasing during last 25 years. Recent study shows that the shortage of the aquifer is about 16 meters and land subsidence is 0.5 1.2 meters. Long deep cracks are foun...

Title of Document: A BALANCING ACT? —AN EMPRICIAL EXAMINATION OF WHETHER THE DYNAMIC BALANCE POLICY HAS HELPED CHINA RECUDE CULTIVATED LAND LOSS AMID RAPID URBAN LAND EXPANSION Juan Feng Doctor of Philosophy 2011 Directed By: Professor Erik Lichtenberg Agricultural and Resource Economics Associate Professor Chengri Ding Urban Studies and Planning For decades, the Chinese government has been con...

The growing expansion of agricultural activities without consideration of the potentialities and limitations of land constitutes a potential source of environment degradation. This work aimed to evaluate the physical proprieties of lands in the micro bosin of Una, Sapé in the state of Paraiba, Brazil, using the classification of the land use capacity . The area is located in the eastern part of...

Thermal imagery is widely used to quantify land surface temperatures to monitor the spatial extent and thermal intensity of the urban heat island (UHI) effect. Previous research has applied Landsat images, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images, Moderate Resolution Imaging Spectroradiometer (MODIS) images, and other coarseto medium-resolution remotely sens...

The primary goals of land-use planning are enunciated. A plea is made for consideration of the total biosphere and not just its separate components. The environmental impact statement process is reviewed and some suggestions made for its strengthening. Moves for international adoption of this process are noted, as well as the concept of eco-development currently under examination by UN agencies.

A worldwide climatology of the diurnal cycles of low clouds is obtained from surface observations made eight or four times daily at 3or 6-h intervals from weather stations and ships. Harmonic fits to the daily cycle are made for 5388 weather stations with long periods of record, and for gridded data on a 58 3 58 or 108 3 108 latitude–longitude grid over land and ocean areas separately. For all ...

Precise global/regional land cover mapping is of fundamental importance in studies of land surface processes and modelling. Quantitative assessments of the map quality and classification accuracy for existing land cover maps will help to improve accuracy in future land cover mapping. We compare and evaluate four land cover datasets over China. The datasets include the Version 2 global land cove...

in developing countries, it is common to site (or locate) industries without environmental impact assessment. in this study the impacts of two food processing industries on land use and land capability, noise and vibration, environmentally sensitive areas and visual quality as environmental elements were investigated. the research method adopted was the investigative survey research approach (i...

Digital change detection is the process that helps in determining the changes associated with land use and land cover properties with reference to geo-registered multi temporal remote sensing data. Puer and Simao, where land use has been greatly affected by recent government policies that aim to balance the need to encourage rural development with ecological stability. These policies include pr...
