Abstract

Smallholder farmers’ vulnerability to climate-related disasters in Sub-Saharan Africa is increasing, partly due to land-use changes and poor adoption behavior for Disaster Risk Reduction (DRR) measures. Such behavior can be explained by poor beliefs about DRR measures due to limited access to information. Agricultural extension workers are increasingly less trusted because they tend to transfer information less targeted to DRR and have limited spatial coverage. We apply the Theory of Planned Behavior (TPB) to explain the adoption behavior for DRR measures and further investigate whether Social Information Networks (SIN) explain the behavior beyond the TPB determinants. Cross-sectional data were collected from 602 randomly selected households from Rwenzori and Ankole in Western Uganda, the sub-regions that are prone to landslides and floods. Results from the Structural Equation Modeling (SEM) demonstrate that TPB explains the adoption behavior with Perceived Behavioral Control (PBC) as a stronger driver of intentions than subjective norms and attitudes. The intention to apply DRR measures is significantly associated with actual adoption. Farmers’ behavior to control landslides and floods is correlated because the same location is at risk of such interacting disasters. Moreover, SIN also significantly predicts adoption intentions through the three theoretical predictors by playing a moderating role. PBC and professional networks being the main drivers of adoption intentions suggests that the role of extension services cannot be substituted by informal social networks but the two should be complementary. Thus, the study shows the need to build the technical capacity of extension staff and informal networks in DRR measures to share information with farmers.
