Optimizing sustainable development in arid river basins: A multi-objective model balances water, energy, economy, carbon, and ecology
A collaborative research team from Beijing Normal University and the University of Regina has introduced a new approach to sustainable development in arid river basins through a Grey Fractional Multi-Objective Programming (GFMOP) model. The study, recently published, focuses on balancing water, energy, economy, carbon emissions, and ecological considerations to provide a comprehensive solution for resource management in arid and semi-arid regions.
The researchers applied this model to the Tarim River Basin in Northwest China, a critical region suffering from water scarcity and environmental degradation. The study explored 32 scenarios, examining factors such as carbon removal rates and water conveyance efficiency.
Key findings indicate that improving water use efficiency can simultaneously reduce carbon emissions and safeguard the environment. Wind power development is highlighted as a priority, with its share in the energy structure projected to rise to 23.3% by 2060. Additionally, promoting carbon capture technologies and expanding grassland coverage are crucial for achieving regional carbon neutrality.
This study provides detailed strategies for resource allocation and pollutant control, offering valuable guidance for policymakers and stakeholders aiming for sustainable and balanced watershed management.
