The Global Alliance for Improved Nutrition is inviting organisations to submit concept notes for an evaluation of their Marketplace for Nutritious Foods Program in Kenya. The programme supports small and medium enterprises producing nutritious foods to overcome barriers to growth. The aim of this three-year evaluation is to measure impact of investments through SMEs to increase availability, affordability and convenience of nutritious foods in markets that serve low-income communities. Organisations will design and conduct the impact evaluation, using both qualitative and quantitative methods. Selected organisations will be invited to submit full proposals. The deadline to submit concept notes is 12 March 2018.
