Humidtropics adopts an integrated systems perspective. Instead of tar-geting one single pre-selected commodity and trying to boost its produc-tivity at farm level, Humidtropics focuses on stimulating productivity, nat-ural resource management (NRM) and institutional innovations across different levels in order to achieve more sustainable impacts. It consid-ers all farm enterprises and their interactions, as well as nutrition, social differentiation (e.g.

Utilization of systems approach using multistakeholder process as modality of intervention has been increasingly experimented in agricultural research in tropical zones. Recent research findings indicated strong evidence of the positive contribution of research for development (R4D) and innovation platforms (IP) in increasing the impact of research for development interventions. However, specific factors of the process leading to higher impact yet to discovered.

Farmers in the Lake Victoria crescent zone have over the years struggled with pests and diseases in a country full of fake agricultural inputs, access to markets, post-harvest losses, declining soil fertility and the changes of weather. The production for most farmers is rain fed and is greatly affected by climatic changes. The Mukono Wakiso innovation platform (IP) was formed to help farmers find solutions to these issues.

Rural extension is a process of work and accompaniment with the producer aimed to sustainable development of their skills. In Mexico, a series of extension models have been adapted, that goes from the US, implemented in the early 1980’s, to the hub model or innovation node (platform - demonstration module - extension area) applied since 2010 under the MasAgro Program. The aim of this paper is to analyze the various processes of extension in Mexico.
