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...

Despite expanding interest in nature's contributions to people (NCP) studies, understanding of sacred natural sites’ contributions to human society and the restoration of fragmented landscapes remains relatively limited. This study examines the diversity and extent of NCP by church forests in a fragmented tropical landscape in southern Ethiopia. We...

“Jefoure” refers to a traditional grass-covered road with households settled on both sides in the Gurage socio-ecological production landscape in Ethiopia. We assess Nature’s Contributions to People (NCP) on Jefoure roads for sustainable management. Data were collected using survey tools and orthophoto images, and they were systematically analyzed...

Information about cultural landscape settings and characteristics is essential for understanding and finding solutions for their sustainable management. In the Gurage socio-ecological production landscape of Ethiopia, “Jefoure” refers to a traditional grass-covered road with households on either side. This study aims to map and characterize Jefoure...

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...

Policy Brief

アジア太平洋地域の発展途上国で進んでいる森林減少の最大の要因は、違法かつ持続可能でない伐採である。違法伐採によって木材輸入国が安価な木材を大量に輸入できる一方で、輸出国の自然環境、森林の管理・経営(ガバナンス)、そして森林に依存して暮らしている人々の生活が犠牲になっている。木材輸入国においても発展途上国の適正な森林管理を促進する義務があることを認識して、現在多くの政府が合法で持続可能な木材の調達を支援する公共調達政策を導入している。これは、持続可能な開発を進める上で国際貿易を活用する極めて重要な一歩である。

本ポリシー・ブリーフは、日本、英国、オランダ及びフランスで実施されている木材公共調達政策を比較し、各国の手法の共通点と相違点を検証しながら...
