Adoption determinants of improved cassava varieties and intercropping among East and Central African smallholder farmers

Abstract

A key constraint to cassava productivity in Africa is the lack of adoption of improved cassava varieties tolerant to pests and diseases. To understand the drivers of adoption behavior, we examine the simultaneous adoption of improved cassava varieties and intercropping by 1200 smallholder farmers in Malawi, Tanzania, and Uganda. Using a linear model, we find that varietal characteristics, such as yield and early maturity, are critical drivers of adoption. Access to extension and credit is associated with an increase in the attractiveness of yield‐improving characteristics. We conclude that a more targeted extension approach would increase technology adoption in these countries.
