Redesign of agricultural systems is essential to deliver optimum outcomes as ecological and economic conditions change. The combination of agricultural processes in which production is maintained or increased, while environmental outcomes are enhanced, is currently known as sustainable intensification (SI). SI aims to avoid the cultivation of more land, and thus avoid the loss of unfarmed habitats, but also aims to increase overall system performance without net environmental cost. For example, large changes are now beginning to occur to maximize biodiversity by means of integrated pest management, pasture and forage management, the incorporation of trees into agriculture, and irrigation management, and with small and patch systems. SI is central to the Sustainable Development Goals of the United Nations and to wider efforts to improve global food and nutritional security.
农业系统的重新设计对于在生态和经济条件发生变化时取得最佳成果至关重要。目前,将生产维持或提高的同时,增强环境效果的农业过程结合起来被称为可持续集约化(SI)。SI 的目的是避免耕种更多的土地,从而避免未耕种生境的丧失,同时还旨在提高整体系统性能,而不会造成净环境成本。例如,现在正在通过综合虫害管理、牧场和饲料管理、将树木纳入农业以及灌溉管理以及小型和分散系统,开始进行大规模的改变,以最大限度地提高生物多样性。SI 是联合国可持续发展目标以及更广泛的提高全球粮食和营养安全努力的核心。
