Salinity is one of the major drivers of environmental change and a persistent stressor in coastal areas, often resulting from prolonged storm and tidal surge flooding. Especially in case of the Asian Mega Deltas, where vast number of communities depends on coastal agriculture as sole livelihood, salinity is compounding as an immediate as well as...

　地域で創出された再生可能エネルギーを地域で消費する再生可能エネルギーの地産地消の担い手として、自治体が自ら事業に関与していく「地域電力小売事業」の取組は、近年の再生可能エネルギーや地域分散型エネルギーの導入拡大・電力小売事業の全面自由化などの流れを背景に、各地で拡大してきた。 　自治体が自ら事業に関与している「地域小売電気事業者」は全国で30を超えており、各地の地域特性や課題、事業環境を踏まえた事例が創出されている。反面、自治体が「地域電力小売事業」に取組むうえでの課題も見え始めている。また、今後競争が激しくなることが想定され、その中で事業者として付加価値がある提案を行うことが課題となっている。 　本書では、上記背景を踏まえて、自治体から出資を受けている新電力会社（地域新電力...

To classify Very-High-Resolution (VHR) imagery, Geographic Object Based Image Analysis (GEOBIA) is the most popular method used to produce high quality Land-Use/Land-Cover maps. A crucial step in GEOBIA is the appropriate parametrization of the segmentation algorithm prior to the classification. However, little effort has been made to automatically...

将来のCO2排出量は、経済規模、産業構造といった「社会的前提要素」 と、気候変動政策の対象となるエネルギー効率、エネルギーの供給構成などの「対策対象要素」によって左右される（図a参照）。本稿は、日本の国別緩和目標(NDC 1)に記載される2030年GHG削減目標（以下、NDC目標）におけるエネルギー起源CO2排出量（以下、CO2排出量）に着目し、社会的前提要素（実質GDP）及び対策対象要素（実質GDP当たりの最終エネルギー消費量、最終エネルギー消費当たりのCO2排出量）がどのような水準であるのか考察 することを目的に、各要素について、既往の統計や研究等による推定結果と比較した。さらに、個々の要素の変化に対しCO2排出量がどのように変化するか、定量分析（感度分析）及びLMDI法...

This paper outlines the Talanoa Dialogue and the Global Stocktake, with a view to seeking their mutual implications. In particular, this paper aims: 1) to summarise and provide an overview of the current status of the Talanoa Dialogue and Global Stocktake; 2) to examine the commonality, differences, and linkages between the stocktakes that have...

Parties to the Paris Agreement agreed to ensure avoidance of double counting of emissions reductions from the use of international market mechanisms. Although useful data may be available, Parties have limited experience and guidance from the UNFCCC on what data to report in the transparency framework pre-Paris Agreement. If the current reporting...

A new method for classifying land cover features in high resolution satellite imagery was developed. The method involves (1) performing image segmentation to delineate homogeneous ground objects in the image, and (2) using a convolutional neural network classifier to extract the land cover of the segments (i.e. whether they represent buildings...

Literature suggests a significant potential for synergies among climate change adaptation and mitigation (CCA & M) policies, especially in urban areas. However, the understanding of how best to integrate CCA &M is limited despite the fact that there is an increasing interest, particularly in Southeast Asian countries, in achieving the integration...

This study uses a spatially-explicit land-use/land-cover (LULC) modeling approach to model and map the future (2016–2030) LULC of the area surrounding the Laguna de Bay of Philippines under three different scenarios: ‘business-as-usual’, ‘compact development’, and ‘high sprawl’ scenarios. The Laguna de Bay is the largest lake in the Philippines and...

This policy brief advocates the landscape approach in areas where competing demands on land and natural resources in the Asia-Pacific region can be observed. The landscape approach enables development while protecting and enhancing ecosystems and their services. Definitions, a set of normative principles and recommendations, including building on...
