循环利用:加强循环利用意味着降低农业生产的经济和环境成本

浪费是一项人为提出的概念—在自然生态系统中并不存在浪费。生态农业方法通过模拟自然生态系统,支持推动在生产系统内进行养分、生物质和水分循环的生物过程,从而提高资源利用效率,并将浪费和污染降至最低。

循环利用可通过多样化并在不同组成部分与活动之间构建协同效应,在农场层面和景观范围内进行。比如,包括根系深植树木的农林复合系统能够捕获一年生作物根系无法吸收的养分。农牧系统通过利用粪便进行堆肥或直接施肥,并将作物残茬和副产品用作家畜饲料,推动了有机质的循环利用。养分循环占所有非供给性生态系统服务经济价值的51%,畜牧业的融入在其中发挥着主要作用。同样,在稻田养鱼系统中,水生动物协助对水稻作物施肥并减少有害生物,降低了对外部肥料或杀虫剂等投入品的需要。

循环利用通过闭合循环和减少浪费提供了多种惠益,降低了对外部资源的依赖,提升了生产者的自主能力,降低了面对市场和气候冲击时的脆弱性。循环利用有机质和副产品为生态农业创新提供了巨大潜力。

European agriculture and food systems are strongly impacted by many challenges such as soil erosion and degradation, water quality, loss of biodiversity, food insecurity, access to land and other productive resources, farmers' indebtedness, loss of farms, and climate change. Agroecology, as a way to design, develop, and promote the transition...

It is widely recognized that a radical transformation of food and agriculture systems is urgently needed in order to address converging social, economic, health and ecological crises. The potential of agroecology to transform food systems and render them more resilient, sustainable and inclusive is increasingly recognized and backed by a...
