The rising demand for food, energy and water amidst depleting supplies and increased environmental degradation is a significant problem in today’s world. The concerted occurrence of climate change, human hostilities, poverty increase in several countries and a pandemic outbreak have all contributed to the global challenge of food insecurity. Sustainable management of the three essential resources requires a paradigm shift from a singular and separate approach where each of the resources is independently treated to a multi-dimensional approach that recognises the interconnectedness of the resources, referred to as the Food-energy-water-nexus (FEW-N). A critical and holistic study of optimum interconnections in the FEW-N within social, environmental and economic framework is required. The paper leverages on multi-objective sustainable land use allocation models, integrated with energy and water resource allocation challenges in the food sector, taking cognisance of the FEW-N. Result validation was carried out under different scenarios within the South African context. The results demonstrate the robustness of the developed optimisation framework in introducing optimality amongst multiple objectives while exploring the trade-offs amidst competitions. Furthermore, results show that sustainable management of territorial and natural resources enhances food security amidst depletion of resources.

在供应枯竭和环境恶化加剧的情况下，对食品，能源和水的需求不断增长是当今世界的一个重大问题。气候变化，人类敌对行动的共同发生，若干国家的贫困增加以及大流行的爆发都加剧了全球粮食不安全的挑战。三种基本资源的可持续管理需要从单一和单独的方法转变为单一的方法，在这种方法中，每种资源都被独立地对待，转变为承认资源相互联系的多维方法，即粮食，能源，水，能源等。 （FEW-N）。需要对社会，环境和经济框架内的FEW-N中的最佳互连进行全面的批判性研究。本文充分认识到FEW-N，利用多目标可持续土地利用分配模型，将其与食品部门的能源和水资源分配挑战相结合。结果验证是在南非范围内的不同情况下进行的。结果证明了开发的优化框架在引入多个目标之间的最优性的同时探索竞争中的权衡的鲁棒性。此外，结果表明，在资源枯竭的情况下，对领土和自然资源的可持续管理可增强粮食安全。结果证明了开发的优化框架在引入多个目标之间的最优性的同时探索竞争中的权衡的鲁棒性。此外，结果表明，在资源枯竭的情况下，对领土和自然资源的可持续管理可增强粮食安全。结果证明了开发的优化框架在引入多个目标之间的最优性的同时探索竞争中的权衡的鲁棒性。此外，结果表明，在资源枯竭的情况下，对领土和自然资源的可持续管理可增强粮食安全。
