The response of land surface phenology (LSP) to the urban heat island effect (UHI) is a useful biological indicator for understanding how vegetated ecosystems will be affected by future climate warming. However, vegetation cover in rural areas is often dominated by cultivated land, whose phenological timing is considerably influenced by...

River meandering and anabranching have become major problems in many large rivers that carry significant amounts of sediment worldwide. The morphodynamics of these rivers are complex due to the temporal variation of flows. However, the availability of remote sensing data and geographic information systems (GISs) provides the opportunity to analyze...

With the advent of high-spatial resolution (HSR) satellite imagery, urban land use/land cover (LULC) mapping has become one of the most popular applications in remote sensing. Due to the importance of context information (e.g., size/shape/texture) for classifying urban LULC features, Geographic Object-Based Image Analysis (GEOBIA) techniques are...

日本の「レンジャー」が体験したアメリカの国立公園での長期滞在ボランティア。それは、それまでの“アメリカの国立公園”観を覆す衝撃的な体験だった。国立公園到着の翌日から始まった体当たりのフィールドワーク、２度のアメリカ横断。２つの国立公園での長期研修と首都ワシントンでの内務省魚類野生生物局での実務研修を通じてようやく理解できたアメリカの自然保護政策とは！？　ボランティアの活用、モニタリング調査、イメージ戦略など、国立公園を訪れただけではわからない舞台裏を、日米の国立公園と国立野生生物保護区の比較しながら描き出す。国立公園ボランティアへの応募や国立公園での生活の様子などもまじえながら、アメリカの国立公園でのボランティアの役割や活躍の様子なども紹介。なお...

A new method was developed for mapping forest, agricultural, and urban land cover using remote sensing imagery. It is designed to better detect small land cover objects (e.g. small forest or agricultural patches) and monitor their change (e.g. fine-scale deforestation) using freely-available satellite imagery.

Asian cities have faced problems caused by rapid urbanization for decades. While urbanization can bring economic development to the cities, it also produces decrease of natural resources or environmental deterioration. From the perspective of fresh water related issues, Asian cities are suffering from scarcity of water resources and water...

Many Asian cities have greatly relied on groundwater in the course of their development. Large populations and concentrations of industrial activity in urban areas intensified the stress on groundwater. Such stress has resulted in environmental problems, such as the drawdown of water tables, land subsidence and saltwater intrusion, which interfered...

The goal of the Forest Conservation Project is to develop strategies for desirable forest conservation and sustainable forest management. Although many approaches should be taken into consideration to achieve this goal, the project has set a precise objective for its second phase of research (April 2001 to March 2004): to propose concrete measures...

Climate security refers to the direct and indirect impacts of climate change on peace and security. It also refers to the impact of climate change on the political stability, human security, national security, etc. Climate change as a threat multiplier, can exacerbate the underlying traditional security issues and human security issues. Hence...

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...
