<p>The adequate production and supply of a diversity of foods will continue to be the foundation of food security. Constraints to food production are many and are intensifying, generating concerns about the ability of food systems to meet global food needs. An impressive array of agricultural technologies and management interventions is available to address many food production constraints in major farming systems. Yet, alone these solutions may be inadequate. For example, most of the interventions to sustainably intensify food production systems require repeated large investments in costly inputs and timely implementation across extensive land areas, which is challenging for farmers to consistently achieve. To increase food production and food diversity to better attain food security for all into the future will require far greater emphasis on farm management, on-farm participatory research, farmer capacity building and support to farms.</p>
