System-level agro-ecological transitions require policy support for experimentation and exchange of knowledge by farmers, community- based participatory methodologies and market and policy measures, for example, public procurement, local and regional market support, regulation or payments for environmental services . Scientific consensus about the food security and environmental implications of agro-ecological transitions on a global scale is lacking. Yields of agro- forestry and organic farming can be lower than high-input agricultural systems but, conversely, AF can boost productivity and profit, varying according to the time frame and the socioeconomic, political or ecosystem context   . Such contrasting results and the limited investment in agro-ecological research to date mean it is paramount to assess the global and regional impacts of agro-ecological transitions on food production, ecosystems and economies in the context of climate change adaptation  .
