Book excerpt: FAO is a global knowledge broker for the agri-food industry, including technologies for production and processing. In particular, the Agro-Industries Programme of FAO is increasingly tending to focus on appropriate input supply, innovation and value chain development. Improvements in these areas have the potential to sustain and improve livelihoods and well-being at whatever scale and in whatever region of the world. Within the World Congress on "Agricultural Engineering for a Better World," as a preparation for the challenges of the twenty-first century, FAO conducted two workshops. The first targeted the subject of "challenges for agricultural mechanization in sub-Saharan Africa," and the second focused on "using technology to add value and increase quality." This report contains the results of the Congress, and encourages both readers and decision-makers to consider the important role of engineering technologies for development and, indeed, for a better world.
