| Summary: | The tef-Acacia decurrens-charcoal production agroforestry system (TACPA system) is a conventionally and uniquely adopted indigenous potential climate-smart agricultural technology (CSAT) in northwest Ethiopia. This study investigates factors determining farmers’ adoption and intensity of use of the TACPA system using a descriptive statistic and a double-hurdle model. A total of 326 farming household heads were selected using multistage random sampling from two purposively chosen provinces. The descriptive statistics showed that 64.42% of the local farmers adopted the TACPA system, and the area covered by the adopter was 0.38 ha. Empirical estimates of the first hurdle revealed that credit, plot ownership, association, primary road distance, asset, farming experience, labor, family size, livestock, tenure, and marginal land influenced the adoption of the TACPA system. On the other hand, estimates of the second hurdle showed that the intensity of use of the TACPA system was determined by age, plot ownership, nativity, primary road distance use, livestock, tenure, secondary road distance, and experience. The complementarity between the adoption of the TACPA system and its intensity of use suggests the necessity of joint socio-economic policies to meet the priority needs of smallholder farmers of the study area and to disseminate the innovation to other parts of Africa with similar environmental conditions. © 2022 by the authors.
