“…Sánchez, 2018 presents a review of various modelling frameworks, from biophysical modelling, economic and IAMs in the context of climate impacts and inequalities, highlighting how both top-down and bottom-up approaches are essential to cover more or less regional and sectoral details (Sánchez, 2018). Recent development of Climate Impact Models (CIM), with high spatial and temporal resolution and highly detailed bio-physical interactions between atmosphere, land, and water have made these tools useful and complementary to IAMs in studying climate policy implications (Nozaki et al, 2023;van Maanen et al, 2023). In this study, we explore how climate geo-and bio-physical climate impacts in the water, energy and land affect the investment and operational cost to achieve sectoral-related SDG targets.…”

Achieving the Sustainable Development Goals (SDGs) necessitates a comprehensive understanding of the intricate relationships among water, energy, food, and land resources, particularly in the context of a growing global population and climate change. This paper explores the interplay between climate impacts and investment requirements for achieving sectoral-related SDG targets, employing the MESAGEix-GLOBIOM-Nexus model to analyze cost-optimal investment portfolios. By integrating biophysical sectoral climate impacts, including changes in water availability, crop yields, and energy demand for cooling services, the study assesses the economic implications on the SDG investment portfolios that enhance climate resilience. Our findings underline the cross-sectoral economic benefits of achieving nutrition and food waste policies, revealing significant reductions in water withdrawal-related expenditures, particularly in South Asia. Climate impacts introduce uncertainties on the expected SDG investments and Operation and Maintenance (O&M) costs, leading to potential expenditure increases, especially in water-scarce regions. The study also highlights the importance of considering long-term costs and uncertainties to maintain SDG targets’ standards throughout the century, with investment requirements in Asia that could vary from 10 to 30 percentage points, emphasizing the need for climate resilience-building measures in water infrastructure to address extreme climate events. This research contributes to understanding the complex interactions between climate impacts, socio-economic development and SDG achievement, offering insights for policymakers and stakeholders to navigate investment in pursuit of climate-resilient sustainable development. At the same time, it provides agenda inputs for research and modelling of integrated climate impacts.

The United Nations has reported that the world is off track to achieve water sustainability and this has been exacerbated by climate change. Studies indicate that water-related sustainable development goals (SDGs) have significant synergies and trade-offs involving various sectors. We measure the synergies and trade-offs between climate actions (mitigation and adaptation) and five water-related SDG targets based on a global numerical simulation driven by climate change and socioeconomic scenarios. We found that synergies outweigh trade-offs in all regions regarding water-related targets, with an approximately five-fold difference in the globally affected population. The main trade-off source is increased water use due to economic development in Africa and Central/South America, and increased irrigation water if bio-energy crop production is enhanced in Africa and North Africa, suggesting that more coordinated policy-making is needed between climate action and water management in these regions.
