This eight-page brief summarizes what WorldVeg does, and why. It introduces the problem, and the key role of vegetable research and development in overcoming some major global challenges. It explains what we need to do to address food system issues, and the WorldVeg push-pull-policy approach, of simultaneously tacking production, consumption and policy issues. It then outlines solutions to these food system issues, as a ‘menu’ of four overarching priority actions grouped under investment, nutrition, livelihoods and resilience.
