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。

Animal diseases and zoonoses, infectious diseases that can be transmitted between animals and humans, are a global socio-economic and public health problem. Ensuring the surveillance and control of these diseases implies identifying high risk areas. Maps of these areas can be produced using spatial multi-criteria evaluation, a recent method that...

The soil environment is likely the most complex biological community. Soil organisms are extremely diverse and contribute to a wide range of ecosystem services that are essential to the sustainable function of natural and managed ecosystems. The soil organism community can have direct and indirect impacts on land productivity. Direct...

Around the world, women forge change in their communities using agroecological approaches. Yet, surprisingly little has been written about this subject. This issue of Farming Matters shows how women can transform a situation of exclusion, crisis and social vulnerability, into a positive spiral of innovation, solidarity, and personal growth.

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...
