为了满足对资源、粮食和能源的需求，特别是在全球南部快速发展的国家，需要新的基础设施投资、技术和供应链。至关重要的是，管理一个过渡，尽量减少对全球环境退化的影响，同时有利于当地的社会经济发展。优化自然资本资源并考虑更广泛的环境和社会经济可持续性的粮食-生物能源一体化提供了一条前进的道路。本研究提出了一种综合方法，使整个系统建模，以解决资源-食品-生物能源系统的相互联系和相互作用，并优化考虑多中心决策空间的供应链。生命周期可持续性评估、优化、基于代理的建模和模拟结合起来，建立了一个适用于资源-粮食-生物能源关系的综合系统建模框架。模型构建模块之前，他们的应用程序在三个案例研究解决农业残留物和大型真菌在菲律宾，甘蔗生物精炼在南非，和尼帕棕榈生物燃料在泰国。我们的案例研究揭示了未开发的生物质的巨大潜力，包括农业废物和在边缘土地上生长的非粮食生物质。两个价值链一体化案例研究-菲律宾的秸秆-真菌-能源和非洲的糖-能源-被建议作为可持续的解决办法，将废物回收为增值产品，以满足粮食和能源安全。案例研究突出说明了如何应用综合建模框架解决多层次问题，同时考虑到不同层次的决策，这有助于实现总体可持续性目标。
To meet the demands for resources, food and energy, especially in fast developing countries in the Global South, new infrastructure investments, technologies and supply chains are required. It is essential to manage a transition that minimises the impacts on global environmental degradation while benefits local socio-economic development. Food-bioenergy integration optimising natural capital resources and considering wider environmental and socio-economic sustainability offers a way forward. This study presents an integrative approach enabling whole systems modelling to address the interlinkage and interaction of resource-food-bioenergy systems and optimise supply chains considering poly-centric decision spaces. Life cycle sustainability assessment, optimisation, agent-based modelling and simulation were coupled to build an integrated systems modelling framework applicable to the resource-food-bioenergy nexus. The model building blocks are described before their applications in three case studies addressing agricultural residues and macro-fungi in the Philippines, sugar cane biorefineries in South Africa, and Nipa palm biofuel in Thailand. Our case studies revealed the great potential of untapped biomass including agricultural waste and non-food biomass grown on marginal lands. Two value chain integration case studies – i.e. straw-fungi-energy in Philippines and sugar-energy in Africa – have been suggested as sustainable solutions to recover waste as value-added products to meet food and energy security. Case studies highlight how an integrative modelling framework can be applied to address multi-level questions, taking into account decision-making at different levels, which contribute to an overall sustainability goal.
