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...

Illumination variations in non-atmospherically corrected high-resolution satellite (HRS) images acquired at different dates/times/locations pose a major challenge for large-area environmental mapping and monitoring. This problem is exacerbated in cases where a classification model is trained only on one image (and often limited training data) but...

Lichen is an important food source for caribou in Canada. Lichen mapping using remote sensing (RS) images could be a challenging task, however, as lichens generally appear in unevenly distributed, small patches, and could resemble surficial features. Moreover, collecting lichen labeled data (reference data) is expensive, which restricts the...

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.
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...
Policy Brief
This policy brief includes a comparative analysis between Japan's public timber procurement policy and those of several European countries. In addition to identifying a set of elements that public timber procurement policies must include to favour legal and sustainable timber, it provides recommendations for further strengthening Japan's policy on...
