Miguel Altieri talks about the problems of the dominant, industrial-chemical agricultural system and the importance of small scale, agroecological farming as an alternative to meet the needs of food security and protect the environment.

Olivier explains the principles of agroecology and why it is so important for transitioning away from fossil fuel technologies which dominate the industrial food system at present. In practice small scale, locally independent models are best for implementing it. However, if governments support the adoption and spread of agroecological principles it can be scaled up to meet the needs of food security around the world.
