如何在不失去生物多样性遗留物的情况下养活世界？这个问题的两个答案可以在文献中找到。一方面，“土地保护”和“土地保护”范式表明，通过集约化农业系统提高产量将满足人口需求并拯救自然景观。另一方面，“生物多样性友好农业”和“生物多样性农业”认为农业集约化对生物多样性和生态系统特性都有深远的影响，并表明非集约化耕作方法可以保持生态平衡，并且仍然可以生产大量优质食品（粮食安全）。这项工作提出了定性推理（QR）模型，比较了集约化和非集约化农业对水资源，生物多样性和生产力的影响。模拟结果表明，集约农业在保护水资源和生物多样性方面效率低下，在粮食生产和生态系统保护方面的非集约化方法效率较低。

How to feed the world without loosing what is left of biodiversity? Two answers for this question are found in the literature. On the one hand, the “Land Sparing” paradigm suggests that increasing yield by means of intensive agricultural systems would fulfill the needs of human population and save natural landscapes. On the other hand, “Biodiversity Friendly Farming” argues that agricultural intensification has deep impacts on both biodiversity and ecosystem properties and suggests that non-intensive farming practices keep the ecological balance and still may produce large quantities of high quality food (food security). This work presents a Qualitative Reasoning (QR) model that compares the impacts of intensive and non-intensive agriculture on water resources, biodiversity and productivity. The simulations show the inefficiency of intensive agriculture in protecting water resources and biodiversity, and the efficiency of non-intensive approach in terms of food production and ecosystem conservation.
