Optimizing the Combined Allocation of Land and Water to Agriculture in the Omo-Gibe River Basin Considering the Water-Energy-Food-Nexus and Environmental Constraints

A novel optimization model, the Gebre model, effectively resolves land and water allocation conflicts in the Omo-Gibe river basin, Ethiopia, while maximizing economic benefits. By integrating the land-water-food-energy-environment nexus (LWFEEN), this approach minimizes costs, penalties, and environmental impacts, promoting sustainable resource use under climate change mitigation. The model's innovative crop succession concept mirrors real-world farming practices, offering a strategic tool for decision-makers to navigate competing demands in river basins. This study provides a blueprint for achieving sustainable development through integrated nexus-based optimization.
