水-土地-粮食系统对于维持人类基本需求至关重要。虽然对这些资源的需求正在迅速增加，但其可持续性受到众多挑战的阻碍，包括人口快速增长、气候变化、土地使用变化和土地退化。为了实现可持续供应和有效管理这些资源，需要了解所有资源与制约/维持这些资源的因素之间的相互作用。在本章中，采用基于或基于系统思维框架和系统动力学方法的四个系统原型来探索和识别影响沃尔特河流域水-土地-粮食资源关系行为和可持续性的关键系统驱动因素、因素和过程。，西非。原型的发展集中在一个通用的因果循环图构建与利益相关者在以前的研究捕捉人口，水系统，环境和社会经济之间的联系。这些系统原型表明，过去和现在的水和土地以及农业生产管理模式是不可持续的。结果突出了关键领域，这可能是有用的，即使在不确定的系统理解或定量数据的缺陷，当前和未来的可持续管理。
The water-land-food system is essential for sustaining the basic human needs. While the demand for these resources is increasing rapidly, their sustainability has been hampered by a plethora of challenges, including rapid population growth, climate change, land-use change, and land degradation. To attain a sustainable supply and efficiently manage these resources, interactions between all resources and the factors constraining/sustaining them need to be understood. In this chapter, four systems archetypes based or grounded in the systems thinking framework and system dynamics approach were employed to explore and identify the key system drivers, factors, and processes that influence the behaviour and sustainability of water-land-food resources nexus in the Volta River Basin, West Africa. Development of the archetypes centered on a generic causal loop diagram constructed with stakeholders in previous studies capturing the linkages between the population, water system, environmental and socioeconomics. These system archetypes illustrate that the past and the current paradigm of water and land and agricultural production management is unsustainable. The results highlight key areas, which could be useful for the current and future sustainable management, even under uncertain system understanding or deficiencies in quantitative data.
