It amounts to a total vindication of everything OSE and related groups have been saying all along. He says that farming systems relying on closed-loop ecosystems rather than external petrochemicals should be encouraged, as subsistence farmers cannot afford fertilizers and pesticides, the food grown ecologically is better and the environmental impact is smaller. He summarizes the results of various agroecological projects which found that yields more-or-less double, while running costs are greatly reduced.

The report also says that the key to getting these systems implemented is informing the farmers, and that this generally happens on a peer-to-peer basis, rather than from the top down.

It is very encouraging to see that the UN have the same thoughts on food system reform as we do.
