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...

In collaboration with the Institute for Global Environmental Strategies, Japan (IGES), NIES has worked with Bhutan for years to address the adverse impacts of climate change. On February 5-8, 2018, IGES delivered a training program for policymakers, and the Asia-Pacific Climate Change Adaptation Information Platform (AP-PLAT) coordinated lectures...

At the IGES, we have been announcing the top news 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 environmental problems and how it works to create a...
