Capacity building support by means of international development projects for developing countries to prepare national reporting under the Paris Agreement has taken on increasing importance. Given that support for capacity building has been provided for more than two decades, the aim of our research is to assess past trends in capacity building...

パリ協定に掲げる今世紀後半に脱炭素社会(温室効果ガス排出量が正味ゼロの状態)を実現させるためには、経済成長が著しいアジアにおいて、持続可能な低炭素社会の構築に向けた動きを加速させることが必要である。近年、経済成長著しいアジアの都市では、急激な都市化により、資源やエネルギー消費量が増大し、交通量増加に伴う交通渋滞が頻発しており、生活や経済活動に伴う廃棄物、排水、排ガス、温室効果ガス(GHG)等の排出量が増加するなど、住民の生活環境の悪化を招いている。これらの都市の経済成長を維持しながら快適な生活環境を守っていくには、効率的な資源循環や省エネ施策を推進し、環境負荷を最小限に留める持続可能な都市形成にシフトしていかなければならない。 我が国は、開発途上国においてこのような取組を支援すべく、GHG...
Commissioned Report
急激に都市化する開発途上国の都市においては、経済成長を維持しながら快適で持続可能な都市環境を実現していくために、効率的な資源循環や省エネ施策を推進し、環境負荷を最小限に留める「低炭素でレジリエントな持続可能な社会」への移行が重要な課題となっている。昨今、様々な国際的な枠組において、都市・自治体を含む非国家主体の重要性が認識されてきている。本業務では、このような都市の重要性に鑑み、本邦自治体や企業が有する都市の環境改善ノウハウや技術等を開発途上国の都市の課題やニーズに合致した形で提供することにより、都市間連携の強化を図ることを目的に、自治体のニーズ等の調査、パイロット研修の実施や情報発信業務を行った。

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.

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:/...

We developed a fast method for land cover mapping using satellite imagery and crowdsourced geographic data (land use polygon data). The method is less time- and labor-intensive than traditional land cover mapping methods because the crowdsourced data substitutes for training data collected the traditional way (through field survey or visual image...

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.
