抵御力: 提升民众、社区和生态系统的抵御力对于可持续粮食和农业系统十分关键

多样化生态农业系统抵御力更强。这种系统更易从干旱、洪水或飓风等极端天气和其他干扰中恢复,对病虫害的抵御力也更强。在1998年飓风“米奇”袭击中美洲之后,具有生物多样性的农场,例如农林混作、等高耕作和地被间作等,比周边采用传统单作型农场多保留了20-40%的表层土,侵蚀现象较轻,经济损失也较少。

通过维持一定的功能平衡,生态农业系统能更好地抵御病虫害的侵袭。生态农业方法有助于恢复农业系统的生物复杂度,并促进互动生物之间形成必要的集群以自我调节有害生物爆发。在景观层面,多样化农业景观更有潜力实现病虫害防控的功能。

生态农业方法同样能提高社会经济的抵御能力。生产者通过多样化和一体化措施降低其在某一种作物、家畜品种或其他商品歉收时的脆弱性。通过减少对外部投入的依赖,生态农业能降低生产者对经济风险的脆弱性。提高生态系统和社会经济两方面的抵御能力要同时进行。毕竟,人类是生态系统的有机组成部分。

What is the most powerful force that can be unleashed to address the linked challenges of hunger, poverty, climate change, and environmental degradation? They believe it is the creative capacity of the world’s smallholder family farmers, about one third of the world’s population, to continue to organize, innovate locally, and...

For many years, La Vía Campesina and GRAIN have been telling the world about how the agroindustrial food system causes half of all greenhouse gas emissions. But the world's governments are refusing to face these problems head on, and the Paris Summit in December is approaching without any effective commitment...

Bees, butterflies and flies play an essential role in pollinating plants. Without them, humans would have a hard time finding food. Some 75 percent of our most-cultivated crops depend on insect pollination. 87% of all flowering plants need pollinators, we would lose them and their ecosystem services in case of...

The High Level Panel of Experts for Food Security and Nutrition (HLPE) is the science-policy interface of the Committee on World Food Security (CFS). In October 2014, the CFS requested the HLPE to prepare a study on Sustainable forestry for food security and nutrition. The present document is the response...
