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...
This technical report showcases the case study that was conducted as part of the ASEAN Project on Disaster Risk Reduction by Integrating Climate Change Projection into Landslide Risk Assessment (ASEAN DRR-CCA). Its main purpose is to showcase the application of the methodologies described in the guidelines developed as part of this project. The...
The Himalaya and Hindu Kush Region (HKH) is one of the world's most fragile ecosystems in terms of climate change and its impacts, such as, slow- and fast-onset disasters. Traditionally, nature and human beings have co-existed in this area with indigenous and local knowledge (ILK) systems and practices being used in different ways, such as for...
Understanding Myanmar’s solid waste systems presents a challenge for anyone working in the sector. While waste collection and disposal challenges faced by Myanmar’s cities and towns share similarities, strategies to overcome them evolve locally and are often not well-communicated between different local government bodies. Data on the country’s...
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...
IGES JCM Database provides detailed information on the JCM MRV methodologies, projects, feasibility studies, and decision-making processes. The JCM is implemented by the Government of Japan with 17 partner countries; Mongolia, Bangladesh, Ethiopia, Kenya, Maldives, Viet Nam, Lao PDR, Indonesia, Costa Rica, Palau, Cambodia, Mexico, Saudi Arabia...
Both hydropower dams and global warming pose threats to freshwater fish diversity. While the extent of global warming may be reduced by a shift towards energy generation by large dams in order to reduce fossil-fuel use, such dams profoundly modify riverine habitats. Furthermore, the threats posed by dams and global warming will interact: for...
