Aq’Qala county has been categorized as a high flood-prone area in Iran, and faced many major flood events in last two decades (e.g. in 2001, 2002, 2007, 2012, 2017, and 2019). The main aim of the current study is to produce and validate flood vulnerability rate (FVR) maps of this area relying on geospatial data. Vulnerability criteria were...

Climate change and overpopulation have led to an increase in water demands worldwide. As a result, land subsidence due to groundwater extraction and water level decline is causing damage to communities in arid and semiarid regions. The agricultural plain of Samalghan in Iran has recently experienced wide areas of land subsidence, which is...

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...

Since the end of the 1990s, the Sino-Russian border regions have witnessed a dramatic, unprecedented increase in cross-border timber trade that has made Russia the largest log supplier for China's expanding wood industry sector. Driving factors include: severe constraints in China's domestic wood supplies, the availability of rich forest resources...
Policy Report
The guidelines and recommendations for promoting local participation in forest management for Indonesia, Lao P.D.R. and Far East Russia, as the outcome of the second phase research (FY2001-FY2003) of the IGES Forest Conservation Project. This guidelines and recommendations consist of (i) village action guidelines (VAG) for villagers and other...
Policy Report
The aim of this interim country report is to disseminate the results of the activities from the second fiscal year of the second phase, on the Russian Far East, and to provide the basis for discussions on developing guidelines and recommendations for participatory forest management. Under the former USSR, local people were separated from forest...
