The effects of COVID-19 have tested and crushed the earlier achievement in sustaining the agricultural and extension
delivery system globally. COVID-19 has pressed a reset panel on the extension services more especially among the smallholder
farmers who are already underprivileged. Specifically, this review paper aims to analyse studies on the sustainability of
agricultural extension delivery systems in face of the COVID-19 crisis. The various theories and factors advanced in discussing
sustainable agricultural extension delivery systems, and how they contribute to improved production and productivity to end
poverty have been addressed. The COVID-19 mitigation strategies and their effect on agricultural extension sustainability have
been laid bare.
