The United Nations Food and Agriculture Organization, FAO, recently launched the “Save and Grow” farming model, which they describe as “a major new initiative intended to produce more food for a growing world population in an environmentally sustainable way.”
The “Save and Grow” approach targets small-scale farmers in developing countries. It draws heavily on an ecosystems approach to agriculture, meaning that nature’s contribution to crop growth is put to best use. In practical terms, this means using techniques such as conservation agriculture, integrated pest management and precision irrigation.
The approach is detailed in a book and factsheets which can be downloaded or viewed online. Broadcasters may find the descriptions of methods and the discussions to be useful background information or inspiration for farm radio programs. All materials are available in Arabic, Chinese, English, French, Russian and Spanish.
