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。

This podcast mini-series entitled ‘A Feminist Journey Through Agroecology’, co-created by AgroecologyNow and International Cooperation for Development and Solidarity (CIDSE), explores the question of what food systems would look like if they were based on feminist values. When people hear the word 'feminism', they think of women, and of gender, but...

Sustainable Intensification is especially important in Africa where the need is greatest. We present eleven targets for action, paying specific attention to the needs of poor smallholder farmers in Africa. We describe multi-cropping systems integrating new crops developed from culturally-important traditional food species that intensify and enhance the productivity of...

Abstract. The production of sufficient food for an increasing global population while conserving natural capital is a major challenge to humanity. Tree-mediated ecosystem services are recognized as key features of more sustainable agroecosystems but the strategic management of tree attributes for ecosystem service provision is poorly understood. Six agroforestry and tree...

Farming in Europe has been transformed over the last 70 years by policies, technologies, and practices that sought to guarantee a stable supply of affordable food. But success has come at the cost of mounting environmental degradation. Under Horizon 2020, the European Union (EU) funded several research projects dedicated to advancing...
