The 2030 Agenda for Sustainable Development, together with a range of Multilateral Environmental Agreements (MEAs), set an ambitious long-term vision for the universal pursuit of sustainable development through economic, social, environmental and institutional transformation (Chapter 20). Although progress has been made in managing some...

This TWI2050 project seminar is being co-organised by UNU-IAS; the Japan Committee of the International Institute for Applied Systems Analysis (IIASA); the National Institute for Environmental Studies, Japan (NIES); and the Institute for Global Environmental Strategies (IGES); TWI2050 is a global research project developed to support the successful...

Shared socioeconomic pathways (SSPs) have been developed by global climate change communities for analyzing long-term global societal transitions through science-driven analysis. SSPs can be transformed into local-scale socioeconomic pathways; however, the urban scale requires an in-depth understanding of specific local significant factors. Three...

Climate change has been one of the central issues for long-term transformations of cities. However, environmental loads have not been effectively taken into account for future urban plans. Specifically, possible reductions of carbon emissions from cities significantly rely on technological progress and human lifestyle changes, among other factors...

Achieving long term climate mitigation targets for Japan requires deep transformations in the energy system, in particular in the power generation sector. Decarbonization of this sector is unclear due to the uncertain nuclear policy after the 2011 Great East Japan Earthquake. However, many other uncertainties need to be considered, namely the...

We assess the feasibility of Japan’s NDC along with 80% emission reduction by 2050, comparing the role of uncertain nuclear power deployment to other key uncertainties by means of a computable general equilibrium (CGE) model.

This study evaluates the effect of climate uncertainties on the transformations in the global energy system needed for realizing mitigation targets in the long term. Climate uncertainties affect the amount of allowable emissions from human activities that are consistent with a given climate target, and, thus, the range of necessary energy...

SDGs form an indivisible framework. Achieving one goal or target may impact on achieving others. It is important to shift from the conventional siloed approach to an integrated approach by taking account the interlinkages between the targets and among the goals. To contribute to building the knowledge on SDG interlinkages and providing a practical...

Rapid changes in land use and land cover pattern have exerted an irreversible change on different natural resources, and water resources in particular, throughout the world. Khambhat City, located in the Western coastal plain of India, is witnessing a rapid expansion of human settlements, as well as agricultural and industrial activities. This...
