Understanding how biophysical and biochemical variables contribute to the spectral characteristics of vegetation canopies is critical for their monitoring. Quantifying these contributions, however, remains difficult due to extraneous factors such as the spectral variability of canopy background materials, including soil/crop-residue moisture, soil...

Reducing emissions from deforestation and forest degradation (REDD+) has been implemented over the past decade, and has led to a restructuring of forest governance systems in host countries. In the case of the Lao People’s Democratic Republic, which is promoting REDD+, activities have been implemented at national, sub-national and project scales...

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...

The evolution of long-term sustainable societies is closely connected to the transformation of the physical built environment in which those societies operate. We presented a comprehensive set of narratives for the built environment in Japan, consistent with the Shared Socioeconomic Pathways (SSPs) framework, to assess the future evolution of the...

Microplastic pollution is one of the emerging and challenging environmental issues that we face today. Freshwaters, sediment, fauna, flora and air are increasingly reported to be contaminated with tiny plastic fragments and fibres, particles smaller than 5mm. These microplastics often originate from land-based sources such as direct littering...

Contamination by microplastics has become a burning environmental concern due to their rapid distribution in the oceans. Oceans receive a large number of microplastics annually via river waters, direct dumping, and transportation. The cargo ship of X-Press Pearl was sunken in the seabed at a depth of about 21 m which was anchored off Colombo Port...

This chapter contributes to a comprehensive understanding of the island socio-ecological system by a synthesis of the state and trend of, and the drivers of changes in ecosystems and their services, focusing on mangroves in Ishigaki Island. The current extent of mangroves on the Island is limited to small patches along a few river estuaries, which...

The study evaluates the impacts of India’s COVID-19 lockdown and unlocking periods on the country’s ambient air quality. India experienced three strictly enforced lockdowns followed by unlocking periods where economic and social restrictions were gradually lifted. We have examined the in situ and satellite data of NO2 emissions for several Indian...

2022 年8月31日にインドネシアのバリで開催されたG20環境・気候大臣会合では、議長国インドネシアにより議長総括が取りまとめられめた。本ペーパーでは会合成果の主なポイント、課題、来年G7議長を務める日本に期待するリーダーシップについて記載している。

「川崎 脱炭素戦略の行方（下）住民の意識改革カギ：太陽光義務化や地域電力　モデル地区選び推進」 川崎市が環境都市に生まれ変わるには京浜工業地帯の脱炭素化だけでなく、住民の意識改革が欠かせない。市は太陽光パネルの設置義務化やモデル地区をつくることで、住民の行動変容を促そうとしている。 来年度施行へ 川崎市は7月末、環境審議会の脱炭素部会を開き、市内で新築する住宅への太陽光発電設備の設置義務化に向けた素案を示した。設置義務化の方針を表明している東京都の制度案を参考に、規模が大きい建物だけでなく、... （日本経済新聞の記事のページ：https://www.nikkei.com/article/DGKKZO64414520W2A910C2L72000/）...
