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...

2014年11月12日、米中首脳会談後の共同声明において、米国と中国が、以下のような温室効果ガス（GHG）の排出削減目標を発表した。 o 米国：2025年までにGHG排出量を2005年比で26～28％削減 o 中国：2030年頃までに、なるべく早い時期にCO2排出量を頭打ち（ピークアウト）； 一次エネルギー消費における非化石燃料の割合を2030年までに約20% 　本稿では、米中の2020年以降の温暖化対策目標について、既存文献で示される両国の排出経路シナリオと比較することにより、目標の野心度についての評価を行った。評価するに当たり、気温上昇2℃未満抑制に向けた排出経路との整合性、及び目標達成のための追加的な努力の必要性、という二つの評価軸を用いた。前者は環境十全性の視点から評価であり...

Abstract At the sixteenth Conference of the Parties (COP16) for the United Nations Framework Convention on Climate Change (UNFCCC), countries agreed to limit the global mean temperature increase to below two degree Celsius compared to before industrialization. This decision was made together with an agreement to periodically review the adequacy of...
