Les biens et les services écosystémiques contribuent de manière déterminante à la sécurité alimentaire en soutenant la disponibilité, laccès et lutilisation des aliments et en renforçant la stabilité des systèmes alimentaires.
Ecosystem goods and services make critical contributions to food security by supporting the availability, access and use of foods, and by strengthening the stability of food systems. Ecosystem degradation and weak ecosystem governance not only compromise the ability of developing country populations to farm, access and use food effectively, but also undermine the effectiveness of food security policies.
There are two principles here, both reflecting the natural world. The first is that natural systems are based on cycles, for example water, nitrogen and carbon. Secondly, there is very little waste in natural systems.
This comprehensive report outlines a new solution to the biodiversity extinction crisis, in response to its warnings that unless farmers and the world's poorest peoples can learn to coexist with wildlife, hundreds of species may be lost. The approach, called ecoagriculture, seeks to help farmers, most urgently those living in or near biodiversity hotspots, to grow more food while conserving habitats critical to wildlife.
