Land use planning and scheduling under Food-Energy-Water Nexus (FEW-N) considerations is a complicated decision-making problem with resource competitions and conflicting objectives [1]. Systematic thinking based on FEW-N is necessary for modeling and optimization of land use systems [2]. However, challenges arise in making decisions while encountering conflicting objectives, multi-scale and multi-period problems, and multiple stakeholders [3]. To address these challenges, we developed a generic optimization-based land allocation approach, which provides i) a composite FEW-N metric to help solve the multi-objective optimization problem and carry out assessments [4, 5], and ii) a two-stage decomposition strategy to solve the multi-scale and multi-period planning and scheduling problem. The developed strategy was applied in an agricultural land use case study within the Texas Edwards Region. Computational results indicate that the approach can provide a comprehensive FEW-N metric to select strategies for optimal land allocation, limit stresses in the FEW-N, and achieve trade-off solutions for the multi-scale and multi-period FEW land use systems.
