Sustainable Agricultural Practices, Farm Income and Food Security among Rural Households in Africa

Abstract

Abstract Sustainable agriculture has been recognized in the literature as one of the important pathways to ensuring food systems and livelihoods among rural households in Africa. Using data from the ‘Intensification of Food Crops Agriculture in Sub-Saharan Africa (Afrint)’ project, we examine the impact of adoption of multiple sustainable agricultural practices (SAPs) - zero-tillage, intercropping, residue incorporation and animal manure - on farm incomes and food security (captures as self-sufficiency in food production-SSF) among African rural households. Multinomial endogenous treatment effect (METE) method is applied to control potential selection bias. In addition, the multivalued treatment effects (MTE) model and dose-response-functions (DRFs) are also used to examine the treatment effects heterogeneity associated with SAPs adoption. The study reveals that joint adoption of SAPs is increased farm income and food security relative to the adoption of a single practice. Households obtain significantly higher farm income (FI) and food security (FS) via adoption of at least three practices relative to households adopting less than three practices. These findings reaffirm the benefits of adopting SAPs as a package rather than single practice, to enable farm households to derive significant welfare benefits.
