This report summarises the findings of the following OECD initiatives that are particularly useful in considering the integrated implementation of domestic measures in Japan: the latest developments in OECD work on the environmental aspects of responsible corporate behaviour; the latest IPAC developments and good practices in climate policy; and...

Integrating the Sustainable Development Goals (SDGs) into climate actions is essential for a healthy planet and people. Yet, national climate policies and international climate support programs often fail to explicitly recognize the interconnections between climate concerns and other priorities covered under the SDGs. This failure can leave key...

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...

本調査では、スウェーデン、デンマーク、ドイツ、フィンランド及びフランスの 5 カ国を対象に、各国の持続可能な開発目標（SDGs）の①実施体制、②進捗状況の評価方法、③その 他独自の取組を調べた。これらの国は持続可能な開発ソリューション・ネットワーク（SDSN）とベルテルスマン財団が発表している SDG 指数等、SDGs の進捗状況に関する世界ランキ ングで常に上位につけている。これらの国の実施体制や進捗状況の評価方法等を理解する ことは、日本を含む他の国々における SDGs の実施を強化するのに有益と考えられる。 調査は、机上調査と聞き取り調査を組み合わせる手法をとった。机上調査では、各国の自発 的国家レビュー（VNR）、SDGs 行動計画、その他の関連文書を精査した。さらに、5...

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...
