The document discusses ILEIA's LEISA Network, which aims to promote Low External Input Sustainable Agriculture (LEISA) to smallholders in developing countries. Over the past 23 years, ILEIA has developed the LEISA Network through collecting and validating knowledge from practical LEISA experiences, publishing it in LEISA Magazines and on their website, and networking with over 40,000 subscribers in 173 countries. The challenges are to strengthen exchange between the field level and policy level, ensure continuous funding, and increase involvement in regional networks.
