In this study, we measured and characterized the relative dielectric constant of mineral soils over the 0.3–3.0 frequency range, and compared our measurements with values of three dielectric constant simulation models (the Wang, Dobson, and Mironov models). The interrelationship between land cover and soil texture with respect to the dielectric...

Generally, the characterization of land surface roughness is obtained from the analysis of height variations observed along transects (e.g., root mean square (RMS) height, correlation length, and autocorrelation function). These surface roughness measurements are then used as inputs for surface dynamics modeling, e.g., for soil erosion modeling...

This paper presents a collective sensing approach that integrates imperfect Volunteered Geographic Information (VGI) obtained through Citizen Science (CS) tree mapping projects with very high resolution (VHR) optical remotely sensed data for low-cost, fine-scale, and accurate mapping of trees in urban orchards. To this end, an individual tree crown...

Policy Report

Asian cities have faced problems caused by rapid urbanization for decades. While urbanization can bring economic development to the cities, it also produces decrease of natural resources or environmental deterioration. From the perspective of fresh water related issues, Asian cities are suffering from scarcity of water resources and water...

Groundwater has been overexploited in some Asian cities, causing significant problems such as land subsidence. The resource is also under the threat of aquifer contamination. The SWMP project formulated 14 recommendations, beased on teh SWMP study aiming to achieve sustainable groundwater management in the Asian cities. The recommendations...

Policy Brief

Many Asian cities have greatly relied on groundwater in the course of their development. Large populations and concentrations of industrial activity in urban areas intensified the stress on groundwater. Such stress has resulted in environmental problems, such as the drawdown of water tables, land subsidence and saltwater intrusion, which interfered...

Policy Report

The goal of the Forest Conservation Project is to develop strategies for desirable forest conservation and sustainable forest management. Although many approaches should be taken into consideration to achieve this goal, the project has set a precise objective for its second phase of research (April 2001 to March 2004): to propose concrete measures...
