途上国の森林減少・劣化に由来する温室効果ガス排出の削減等(以下「REDD+」という。)は重要な気候変動対策であり、気候変動に関する国際連合枠組条約の第21回締約国会議(COP21)で合意された「パリ協定」にもその実施と支援を奨励することが明記されたところである。 REDD+の推進には、途上国に対する資金と技術の提供が必要とされているが、公的資金には限界があることから、今後、REDD+の取組みを拡大していくには、民間セクターからの資金や技術の提供が鍵となる。しかしながら、民間セクターがREDD+に対して投資するには、排出削減クレジットが獲得できる等のインセンティブが必要(①)とされる。また、途上国がREDD+を実施するには、COP決定を踏まえつつ、各々の国情に応じた排出削減量の算定...

Both hydropower dams and global warming pose threats to freshwater fish diversity. While the extent of global warming may be reduced by a shift towards energy generation by large dams in order to reduce fossil-fuel use, such dams profoundly modify riverine habitats. Furthermore, the threats posed by dams and global warming will interact: for...

This study provides a computationally-simple method to annually update existing national forest maps and model future forest change. It involves integrating national forest maps and global tree cover maps to monitor annual forest change, and then modeling future change by linear extrapolation of the historical trend.

Biofuels are often presented as an environmentally friendly alternative to fossil fuels, however, empirical analysis that is widely reported in the literature shows that biofuel production can have negative environmental and social impacts. The potential for these negative impacts can be avoided through careful planning of biofuel feedstock...

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.
