Agroecological approaches can increase food system resilience , while some agroecological practices such as agroforestry can provide mitigation measures  . Studies testing agroecological approaches have shown robust evidence, medium agreement of increasing adaptation effectiveness through reducing risk, improving food security and yield stability, reducing input costs, and other supporting and provisioning ecosystem services . Effective locally relevant agroecological approaches involve participatory processes, co-creation of knowledge with farmers and attention to social inequities . To address smallholder vulnerability to climate change impacts, however, additional policy support beyond agroecology will be needed that is context specific; for example, addressing farmer capacity, limited political power to access land, water, seeds and other key natural resources, structural gender inequities, policy and market disincentives that support large-scale monocultures  .
