Our impact assessment studies covered all program countries, except Zambia, and are based on two rounds of household panel survey data, excluding Ethiopia for which program effect is estimated using one round of survey data. Impact is estimated using the difference-in-differences method for countries with panel data or, for Ethiopia, based on simple comparison of outcomes between program beneficiaries and non-beneficiaries. The choice of impact indicators is guided by the Sustainable Intensification Assessment Framework (SIAF) framework and survey data availability. Impact indicators encompass the five sustainable intensification (SI) domains discussed in the SIAF: environment, productivity, economic, human, and social.
