This guidebook is intended to provide an overview of how to conduct climate change and land-use change impact assessments,
so that the impacts on water, biodiversity, and health can be better understood at the local level. A key aspect
of the guidebook is the tutorials provided for conducting climate change/land-use change scenario analysis and...
The Asia-Pacific region faces a fundamental dilemma. Over recent decades the region has achieved tremendous economic growth that has lifted millions of its people out of poverty and raised living standards, but in many places the way land is being used to generate this growth is unsustainable. Land has been exploited – growing economies regardless...
This 1-pager shows the potential impacts of land-use change on flooding in the Pila-Victoria subwatershed of The Philippines. The built-up area of the subwatershed is projected to increase by ~88% (based on participatory mapping exercises conducted with local government staff members), which is estimated to result in a ~5% increase in the flood...
This 1-pager shows the potential impacts of land-use change on flooding in the Los Baños subwatershed of The Philippines. The built-up area of the subwatershed is projected to increase by ~65% (based on participatory mapping exercises conducted with local government staff members), which is estimated to result in a ~6% increase in the flood...
平成27 年11 月、日本では「気候変動の影響への適応計画」が閣議決定された。開発途上国の適応計画を支援することは日本の適応計画の戦略の一つとして盛り込まれており、科学的知見に基づいた有効な計画策定の支援を行うこととしている。本業務では、「平成27 年度適応イニシアティブ推進のための地域横断的人材育成等に向けた調査・検討業務」および「平成28 年度アジア太平洋地域における気候変動適応分野の知見共有、人材育成支援業務」を受けて、途上国側政府及び研究機関等との協働が可能となるよう、またアジア太平洋地域の適応に関する能力向上のための人材育成、知見共有等を行うことを目的とし、（１）特定地区における緩和と適応の双方を取り扱うパイロットプログラムに関する業務、（２）適応計画...
グリーンインフラに通じる考え方で、生態系を活用した防災・減災を表すEcoDRR （Ecosystem-based Disaster Risk Reductionの略称）が国際的に注目を集めている。これは、生態系の管理、保全や再生により災害リスクを低減するとともに、人々が日ごろから享受している様々な自然の恵みを守っていこうとするものだ。日本から海外への政府開発援助（ODA）の実施を一元的に担うJICAでは、Eco-DRRを自然環境分野の4つの戦略課題の１つとして、これまでにも関連する取り組みを実施してきた。こうした背景から、海外におけるEco-DRRの社会実装推進にJICAが果たす役割が期待されている。8月30日にグリーンインフラ研究会が開催したセミナーでは、Eco...
Land cover (LC) has a significant impact on rainfall-runoff dynamics of a watershed, so LC maps are often incorporated into hydrological models to simulate how changes in climate or land management will affect water quantity/water quality within the watershed. The accuracy of a LC map can thus affect the accuracy of hydrological modelling results...
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...
