This impact evaluation report quantifies the impacts of Zambia’s Home Grown School Feeding (HGSF) programme – one of the country’s biggest social protection programmes – and the Conservation Agriculture Scale Up (CASU) project, both alone and in combination with each other. The report looks at how the programmes affected farm production and other livelihoods, the food security situation of the household and of school-going children and the educational outcomes of the latter. The report concludes that each programme or programme component considered in isolation meets their strictly defined objectives, but their combination leads to unintended conflicting influence on certain outcomes, thus highlighting the need for increased coherence between programmes. The household and community surveys for the evaluation of the programmes took place between October 2017 and January 2018. The total sample size is 3 636 households and a total of 72 community interviews were also conducted.
