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...

REDD+の効果的な実施に向けた具体的な方策を示すため、REDD+の国際的な制度の動向等について多角的に調査・分析を行い、得られた結果について体系的に整理した。1-1ではUNFCCCを中心とした国際的な議論の動向について取りまとめた。1-2では、既存のクレジット制度である京都メカニズムの共同実施に注目した。1-3では、現在進んでいるREDD+に係る資金拠出に係る取組状況として、緑の気候基金、世界銀行の森林炭素パートナーシップ基金、The REDD+ Early Movers Programについて調査した。1-4では、REDD+に関する政策的な検討や各国の緩和対策の中での位置付けとREDD+活動の実施状況を、JCMパートナー国5カ国(インドネシア、ベトナム、カンボジア、ラオス、コスタリカ...

Developing countries must submit forest reference emission levels (FRELs) to the UNFCCC to receive incentives for REDD+ activities (e.g. reducing emissions from deforestation/forest degradation, sustainable management of forests, forest carbon stock conservation/enhancement). These FRELs are generated based on historical CO2 emissions in the land...

Soil moisture (SM) plays a key role in many environmental processes and has a high spatial and temporal variability. Collecting sample SM data through field surveys (e.g. for validation of remote sensing-derived products) can be very expensive and time consuming if a study area is large, and producing accurate SM maps from the sample point data is...

We use crowdsourced GIS data from OpenStreetMap to help automate the mapping of land cover in Landsat satellite imagery. The OpenStreetMap data had limited area coverage, but was useful for building a model which could classify land cover in the other areas.

Accurate mapping of glaciers is important for management of water resources, studying glacier mass-balance, and monitoring glacier health. However, many glaciers are partially covered by debris of varying thicknesses, and these debris-covered glacier areas are difficult to clearly distinguish from the adjacent valley rock using optical remote...

We analyzed the change in vegetated and urban (impervious) area in the Silang-Santa Rosa sub-watershed of the Philippines to assess the implications related to flood risk. Our main findings were: -The impervious area of sub-watershed increased by 54% (from 3,239 ha. to 4,988 ha.). -The vegetated area decreased by 21% (from 8,509 ha. to 6,760 ha)....

We developed a method for mapping residential areas using freely available satellite imagery. The resultant residential area map can be used for risk assessment (e.g. to estimate the population living in a flood-prone area). Our method can be applied for flood risk assessment in other watersheds in the future.

This dataset can be used by researchers to test different land use/land cover mapping methods using crowdsourced geographic data and Landsat satellite imagery. The study area is the Laguna de Bay area of the Philippines, and the satellite data is from 2014-2015. This dataset will also be available on the "UCI Machine Learning Repository" (https:/...

This paper demonstrates the importance of considering scale issues when estimating the accuracy of land use/land cover maps, particularly when satellite images having different spatial resolutions (i.e. pixel sizes) are used in combination to generate the land use/land cover maps. The results are important for creators and users of these types of...
