Soil moisture is a critical component for Earth science studies, and Synthetic Aperture Radar (SAR) data have high potential for retrieving soil moisture using backscattering models. In this study, polarimetric SAR (PALSAR: Phased Array type L-band Synthetic Aperture Radar) data and polarimetric decompositions including span, entropy/H/alpha, and...
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...
From 1971 to 2010, world trade grew fast by 10% per year on average (World Trade Organization 2011). The rapid growth of international trade contributes not only national economic growth but also increasing environmental pressures, such as raw material extraction and depletion, carbon emissions, water resource deterioration and landscape change and...
With the goal of reporting environmental issues and actions on the formation of sustainable societies in the Asia-Pacific region, since 1998 the Institute for Global Environmental Strategies (IGES) has gathered and compiled news on environmental issues and policies and released them annually as the top environmental news in the Asia-Pacific.
This...
The Institute for Global Environmental Strategies (IGES) has been releasing a collection of the top news items on the environment in the Asia-Pacific region every year since 1998. This has been with the aim of collecting and organising information about environmental issues and policy trends in the region, and to report on how the region addresses...
