Global Environment

In many developing countries, environmental problems—such as ecosystem disruption, biodiversity loss, inadequate waste management, and water and air pollution—are becoming increasingly severe as a result of economic development, population growth, and urbanization. At the same time, global environmental challenges, including climate change, pose serious threats to the stability and prosperity of all countries as well as to human security.

Against this backdrop, this research cluster seeks to stimulate discussion, generate insights, and propose practical solutions for achieving a sustainable human society that lives in harmony with the Earth system. Its current research focuses include methodological development for assessing climate adaptation actions and the formulation of proposals for monitoring frameworks for the post-2030 sustainable development agenda.

Geo-AI for Bridging SDG Environmental Indicator 6.6.1 Data Gaps in Developing Countries: A Case Study of Indonesia

Many environmental SDG indicators, particularly in developing countries, suffer from incomplete or missing data. This also applies to SDG 6 (Ensure availability and sustainable management of water and sanitation for all), and specifically indicator 6.6.1 (Change in the extent of water-related ecosystems over time), due to limited monitoring networks, high costs of data collection, challenging geography, frequent cloud cover, and weak environmental information systems. As a result, countries such as Indonesia rely on proxy data, like land use change, instead of the detailed ecosystem-specific data required by UN SDG metadata. This limits effective SDG monitoring and evidence-based policy making.

Study on the Indicator Framework for Post-2030 International Development Goals

The 2030 Agenda for Sustainable Development was adopted at the United Nations (UN) in 2015. It sets out the Sustainable Development Goals (SDGs), which are 17 goals that all member states should aim to meet by 2030. These are accompanied by 169 targets and 231 indicators (excluding overlaps) to measure how far they have been achieved. However, with so many indicators, no member state has been able to submit data on all of them to the UN. According to the Sustainable Development Goals Report 2022, which is a progress report by the UN on how far the SDGs have been achieved, more than half of the 193 member states have been unable to produce internationally comparable data for as much as eight of the 17 goals since 2015. With the current indicator framework, the burden of data collection is significant for developing countries, which have especially limited administrative resources. This is causing a serious shortage of data, making appropriate progress monitoring of the SDGs and subsequent planning and implementation of measures based on it difficult. Furthermore, although the SDGs originally expect each member state to define its own set of local targets and indicators based on the situations it faces, its policies, and priority issues, efforts have been limited in reality.

Research on Sustainable Development of Developing Countries: an Assessment of the Sustainability of Developing Countries Using the Inclusive Wealth Index and Investigating the Success Factors for Sustainable Infrastructure Development

The question of whether developing countries have achieved sustainable development in the past and how to achieve it in the future is considered one of the most important agenda items for development institutions. The purpose of this study is to examine what measures developing countries should take to achieve sustainable development and what kind of cooperative approach JICA should take as a development institution. Specifically, the project aims to: (1) analyze the sustainability of developing countries (especially in the Asian region) using the "Inclusive Wealth Index", which is an indicator used to measure the wealth of nations; and (2) investigate the success factors for sustainable infrastructure development, which plays a critical role in sustainable development.

Improving the Planning Stage of JICA Environmental and Social Considerations

JICA introduced the guidelines of environmental and social considerations (ESCs) in 2004 and have operated related works for more than 10 years. Quality growth and quality infrastructure are main international agendas and a quality of ESCs is also one part of them. The study aims to propose countermeasures to improve the quality of JICA ESCs, and it reviews and analyzes the quality of JICA ESCs reports, identifies key components to influence the quality, and clarifies a causal relationship between several factors and the quality of reports. The study verifies the causal relationship based on case studies. Eventually the study prepares technical guidelines to improve the quality of reports. The outcomes are expected to improve not only the quality of JICA reports but also the quality of reports prepared in developing countries.

Economic Evaluation of Adaptation Measures to Climate Change under Uncertainty

This study is intended to analyze climate change adaptation measures by applying the techniques that are proposed in the decision-making theory and economic theory with considering the uncertainty of climate change. Climate change is related deeply with uncertainties of various kinds of issues, such as in weather and ecosystem and economic system. The exact interpretation and evaluation of those uncertainties in policy analysis is very important.
Regarding climate change, there is a need for measures from both sides of the adaptation measures and mitigation measures.For long years, the main discussion point of climate change policy was on mitigation measures, but, it is becoming attention gathered in recent years adaptation measures. Although there is growing need for evaluation methods of the international climate change adaptation measures, and the discussion in OECD have been made, still definitive evaluation method does not exist. In this study, we take advantage of the latest knowledge of the methodology related to decision analysis under uncertainty, and make a study of the evaluation methods which can be applied to climate change adaptation measures in the evaluation of future JICA projects. The study, firstly discusses evaluation methods related to climate change adaptation measures in consideration of the uncertainty. And apply to case study "Kenya Mwea Irrigation Development Project (ODA loan projects)". Further draw also general and academic knowledge on climate change policy by combining the information obtained through case studies and a number of economic modeling techniques.

Estimation of the Economic Value of Forests in Ethiopia

Forests offer people various ecosystem services, which include the supply of resources such as lumber, firewood, and fruits and nuts from trees, as well as the protection of water resources and the absorption of carbon dioxide. However, markets for many of the ecosystem services offered by forests do not function properly (either due to market failure or the absence of a market), and market price cannot be used to assess their value. With regard to assessing the (virtual) value of these sorts of services, there are ways to do so using indirect information—including stated preference methods such as contingent valuation methods, as well as revealed preference methods such as hedonic methods—and such methodological research is still thriving in environmental economics.

International Cooperation Strategies towards Green Growth

This study is designed to seek possible new way of development cooperation to achieve inclusive and resilient sustainable development through Green Growth/ Green Economy. Green Growth/ Green Economy is expected to shift a paradigm from "economic and social development with paying attention to environmental conservation" to "sustainable economic and social development while enhancing environmental capital and using environmental benefits in effective and sustainable manner". There is concern that environmental burden will exceed planetary boundary and our planet will be unsustainable, if developing countries trace the same development path of advanced countries. Furthermore, poor people may face further difficulties to graduate from poverty due to their vulnerability to change of environment such as Climate Change. Thus, development cooperation should be reconsidered its optimal way along with new development paradigm, and this study is expected to contribute to form a new trend of international development cooperation including Post 2015/Sustainable Development Goals (SDGs).

Adaptation and Mitigation of Climate Change in Developing Countries

This study consists of two parts: a study on climate change adaptation measures and a study on climate change mitigation measures. The adaptation part forecasts the impact of climate change on countries in Asia and Africa. It proposes measures for local community adaptation and suggests the direction of assistance offered them by developed countries and international organizations. In this regard, it introduces studies undertaken cooperatively by JICA and the University of Tokyo on impact assessments in the Chao Phraya River Basin in Thailand, and findings from a study of the influence of climate change on large Asian cities currently being conducted by JICA-RI. It also seeks cooperation from European and U.S. institutions that are conducting relevant research on Africa. The mitigation part of the study identifies issues confronting the implementation of low-carbon policies using the results of research on carbon reduction in Asia by Japan's National Institute for Environmental Studies.

Conflicts and Cooperation in Resource Governance: State Control of the Public Domain and the Role of Local People in Cross-National Perspectives

This study assesses the way in which developing countries create different systems for resource and environmental governance in the process of economic development and the changes that take place in the roles of ordinary people during the creation of these systems. In general, an economic expansion is accompanied by an expansion of the public sector. In democratic countries, civil society development also is stimulated and clashes of interests over public spaces are intensified. Resource and environmental governance can be viewed as a meeting place for interests concerned with public spaces. Many conventional studies, however, lack a comparative analytical perspective. They either confine themselves to analysis of forests, water and other individual resources or they focus on only a single country, ignoring more generalized discussion of the impact on society of the resource governance process. Furthermore, many policy-oriented studies are limited to specific projects. Learning from these flaws, this study examines conflicts of interest over the distribution of basic resources that occupy key positions in the public space. In particular, it seeks to investigate how space for participatory development is created from the macro-political and historical-institutional viewpoints. The aim is to provide a blueprint for future aid involvement in environmental cooperation.
