Summary: Computable general equilibrium (CGE) models are widely used in assessing the economic, social, and environmental impacts of low-carbon policies. This review analyzed 1002 studies published between 2001 and 2021, revealing the global application of CGE models in low-carbon policy analysis. The study highlights the primary policy focuses, the increasing attention on social and environmental consequences, and the complexity of CGE models to serve diverse policy study purposes.

Summary: The paper analyzes how the Water-Energy-Food Nexus is treated in Computable General Equilibrium (CGE) models, discussing their design, importance, and possible ways of improvement. Most models struggle to represent competing water uses across sectors, highlighting the need to resolve this issue as a necessary step toward improving future research.

Summary: The study finds that a disruption to Chinese cobalt supply may have limited short-term impact on the U.S. economy, but could significantly increase costs if new cobalt demand rises by 2030. By increasing cobalt production, forming trade alliances, and reducing reliance on cobalt in vehicles, economic costs can be minimized in the face of a Chinese supply disruption.

Summary: This study investigates the effects of coupling China's energy tax and water fee policies and provides some simulation results. The results show that the water fee policy has limited effect on water conservation, while the energy tax policy is more effective in improving water-saving efficiency. However, relying solely on existing water and energy tax policies will be insufficient to meet China's water-saving targets without other environmental policies.

Summary: In a context of severe water scarcity and high uncertainty of available irrigation water, the study aimed to determine the mid-term effect of water restrictions on yield and quality of flat peaches. Two treatments were tested: control (CTL) and regulated deficit irrigation (RDI). The RDI treatment resulted in water savings of 33.6% and an increase in irrigation water productivity of 45%.

Summary: Improving water efficiency may lead to a rebound effect by offsetting some water savings; the economy-wide rebound effect of water efficiency improvement in China primarily comes from increased water consumption by households, investors, and governments; in the long run, improving water efficiency can more effectively save water resources.

Summary: The modernization efforts of the irrigation subsector in Kenya have faced multiple challenges, including technical, socio-economic, and institutional issues. While some irrigation schemes have been developed, issues like water scarcity and poor water quality remain. Challenges in terms of cost, credit availability, and market access also hinder irrigation development. However, the future looks promising with the adoption of climate change adaptation strategies such as solar-powered irrigation systems and rainwater harvesting.

Summary: This study develops a salinity-inclusive water scarcity framework for the irrigation sector, and applies it to the Central Valley in California and the Murray-Darling basin in Australia. The results show severe water scarcity in both regions, especially during the summer seasons. The study also explores the potential of alleviating water scarcity through conjunctive use of surface water and groundwater, but highlights the risks of groundwater depletion in certain sub-basins.

Summary: The study examines the local impacts of regional tax cuts using computable general equilibrium simulations. The findings suggest that reducing taxes can lower production costs and stimulate regional economic activity. However, the financing of subsequent deficits and the operation of the regional labor market play a significant role in determining the size, nature, and dynamics of the resulting economic outcomes. Additionally, the decision regarding whether to target labor or capital costs has implications for various regional economic impacts.

Summary: The UK irrigated agriculture sector is considered to be at high risk due to its lowest priority for water allocation during drought events and the resulting impacts of abstraction restrictions. An enhanced version of the D-Risk webtool has been developed to assess the joint multi-scale risks of abstraction restrictions and insufficient irrigation volumes during drought events. This tool provides a holistic understanding of drought risk in irrigated agriculture and supports collaborative decision-making for water management.

Summary: Access to low cost finance is crucial for the transition to green energy in developing economies, but the uneven distribution of capital costs in different regions poses a challenge. Policy interventions that reduce capital costs can accelerate the achievement of net-zero emissions targets in Africa.

Summary: Integrating river system and economy-wide models in a dynamic, iterative, bidirectional fashion allows for assessing economic impacts of interventions in river systems. A coordinated operating strategy in the Nile Basin could help meet water demands in Egypt during periods of scarcity and increase hydropower generation and storage in Ethiopia during high flows. The study introduces a new modeling framework that simulates the Nile River System and Egypt's macroeconomy, showing the potential benefits of this coordinated strategy compared to alternative proposals.

Summary: Technological breakthroughs and policy measures alone are insufficient to achieve the greenhouse gas emissions goals of the Paris Agreement. Transforming linear economic models into closed-loop industrial ecosystems and shifting lifestyle patterns are important for decarbonization. Interdisciplinary research is needed to explore the potential of the circular economy for climate change mitigation and to assess the synergies and trade-offs. Collaboration between different disciplines, methods, and communities can lead to improved quantitative models and better understand the contribution of enhanced circularity performance to mitigation pathways.

Summary: This paper examines the temporal stability of stated preferences for (dis)amenities in uncertain times by surveying the same respondents at two points in time during the Covid-19 pandemic. The results show that individual preferences exhibit some stability in uncertain times, but there are changes in class sizes, indicating that individuals prioritize safety in uncertain times.

Summary: China has launched a national-level carbon emissions trading market with a rate-based cap and benchmarks, and this study assesses the impact of this unconventional trading system on economic development, carbon emission mitigation, and power system transition. The results show that the system facilitates decarbonization of the power sector and reduces carbon intensities of coal and gas power.
