Agricultural development is currently facing unprecedented challenges. With 800 million people already having insufficient access to food, population growth estimates project an even bleaker situation in the future. The article summarizes the major schools of thought regarding how to face the dilemma, and advocates sustainable intensification of agriculture, relying on integrated use of a wide range of technologies to manage pests, nutrients, soil and water. Local knowledge and adaptive methods are stressed rather than comprehensive packages of externally-supplied technologies. The article shows how regenerative, low-input agriculture, founded on full farmer participation in all stages of development and extension, can be highly productive. It is stressed that policy must not prescribe specific, concretely defined technologies or practices, as this would restrict future farmer options. Farmers and communities should be allowed and encouraged to adapt to changing conditions; what needs to be sustainable are local processes of innovation and adaptation.
The article highlights environmental and economic benefits resulting from sustainable intensification practices, for farmers as well as communities and nations with examples are taken from Africa, Asia and Latin America.
Despite the increasing success of sustainable agriculture, it is clear that the challenge remains to ‘scale up’ the process from small ‘islands of success’ to fundamental reform of both policies and policy formulation processes.
