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...

From 1971 to 2010, world trade grew fast by 10% per year on average (World Trade Organization 2011). The rapid growth of international trade contributes not only national economic growth but also increasing environmental pressures, such as raw material extraction and depletion, carbon emissions, water resource deterioration and landscape change and...

近年、木材輸入国において、違法伐採対策が法制度化され実施されている。違法伐採対策法の導入の目的は、その国における違法伐採木材製品の輸入、流通を減少させることである。法律の導入からその目的が達成されるまでには、規制対象である木材輸入事業者 が①自身の行うビジネスが法律の対象であることを認識し、②法律の要求を理解し、③法律を遵守することで、最終的に、④輸入先の変更などの行動変化を起こすというプロセス がある。そして、この目的を達成するためには、政府の法律の執行や運用が重要である。本稿では、ドイツとオーストラリアにおける、政府による違法伐採対策法の運用 状況を報告する。ドイツは、規制対象事業者の検査に重点を置き、EU諸国のうち最も積極的で厳しい法の運用を行っている。一方...

TPP協定「環境章」において、各国による違法伐採の抑止に働く行政措置の強化が規定されるとともに、日EU・EPAの「貿易と持続可能な開発章」においても、各国が違法伐採及び関連する貿易への対処に貢献することが規定されている。これらに対応するために、我が国の違法伐採木材への対策として平成29年5月に施行された「合法伐採木材等の流通及び利用の促進に関する法律」(通称「クリーンウッド法」。以下「クリーンウッド法」という。)を着実に運用していく必要がある。 本事業は、林野庁ホームページ「クリーンウッド・ナビ」に掲載されている生産国リスク情報を、木材関連事業者等の利用者がより活用しやすくするための検討及び情報の整理を行うことを目的とした。具体的には、①リスク情報に基づく基本的な合法性確認(デュー...
