By 2050, nearly 10 billion people will live on the planet. Can we produce enough food sustainably? The synthesis report of the World Resources Report: Creating a Sustainable Food Futureshows that it is possible – but there is no silver bullet. This report offers a five-course menu of solutions to ensure we can feed everyone without increasing emissions, fueling deforestation or exacerbating poverty. Intensive research and modeling examining the nexus of the food system, economic development, and the environment show why each of the 22 items on the menu is important and quantifies how far each solution can get us.

WRI produced the report in partnership with the World Bank, UN Environment, UN Development Programme, and the French agricultural research agencies CIRAD and INRA.
