“…In particular, the impacts of adoption of crop choice only, and soil and water conservation only are 13 per cent and 12 per cent increase in crop revenues, respectively. These findings are consistent with the results reported by Teklewold et al () for Ethiopia and Ng’ombe et al () for Zambia. The results also show that in all the counterfactual cases, adopters would have had lower crop revenues if they had not adopted.…”

Increased climate variability during the last four decades has made the agricultural environment in many developing countries more uncertain, resulting in increasing exposure to risk when producing crops. In this study, we use recent farm‐level data from Ghana to examine the drivers of individual and joint adoption of crop choice and soil and water conservation practices, and how adoption of these practices impacts on farm performance (crop revenue) and exposure to risks (skewness of crop yield). We employ a multinomial endogenous switching regression model to account for selectivity bias due to both observable and unobservable factors. The empirical results reveal that farmers’ adoption of crop choice and soil and water conservation leads to higher crop revenues and reduced riskiness in crop production, with the largest impact on crop revenues coming from joint adoption. The findings also show that education of the household head, access to extension and weather information influence the likelihood of adopting these practices. Thus, enhancing extension services and access to climate information and irrigation can reduce gaps in adoption of soil and water conservation and crop choice, considered as climate‐smart practices that will eventually improve crop revenues and reduce farmers’ exposure to climate‐related production risks.

“…Knowledge is critical for adoption of new agricultural innovations (Meijer, Catacutan, Ajayi, Sileshi, & Nieuwenhuis, ) while extension is critical in imparting agricultural knowledge.

Behaviour of smallholder farmers towards adoption of conservation agriculture in Zimbabwe

Conservation agriculture is critical to sustainably increasing agricultural productivity, enhancing climate resilience and food security. Much research on adoption of conservation agriculture has focused on its agronomic benefits, but little attention has been paid to the contribution of the behaviour of farmers over its adoption. To close this gap, a study was carried out to investigate the behaviour of smallholder farmers towards the adoption of conservation agriculture in Chivi, Murehwa and Mutoko districts, Zimbabwe. Data were collected through a pre‐tested questionnaire administered to 360 farmers, selected through a multi‐stage sampling process. This method was triangulated through focus group discussions, key informant interviews and personal observations. Data were analysed using percentages, means and inferential statistics. The results show that, although fewer than 10% of the respondents had received any formal training in agriculture, more than 80% of them relied on it for their major source of income. The respondents had high levels of knowledge on the social, environmental and economic benefits of conservation agriculture. However, the majority of the non‐adopters had an indifferent perception towards conservation agriculture. The knowledge and perception of the farmers was explained by age, gender, education and experience with conservation agriculture. Results also show a weak but significant correlation between knowledge and perception (Rs = 0.306, p < 0.05), knowledge and adoption (Rs = 0.484, p < 0.05) but a strong and significant correlation between perception and adoption (Rs = 0.808, p < 0.05). Addressing perception gaps is key to enhance adoption of conservation agriculture.

“…In this regard, national and international maize research investments have led to the development and dissemination of several IMVs (Smale and Mason, ). Use of IMVs, especially drought tolerant varieties, acts as an adaptation strategy against climate change (Fisher et al., ) leading to higher and more stable yields and incomes (Manda et al., ; Ng'ombe et al., ). The use of conservation agriculture practices (CAPs) leads to long‐term productivity and environmental benefits—reducing soil erosion, nutrient depletion, off‐site sedimentation, and conserving soil moisture—and reducing labor and draft power use (Jaleta et al., ).…”

“…Yet, farmers rarely use a single agricultural technology but rather a combination of complementary technologies adopted in a sequential manner over time (Aldana et al., ; Leathers and Smale, ), which needs to be accounted for in adoption and impact studies. Past studies that have assessed the impacts of MATs also used cross‐sectional data (e.g., Kassie et al., ; Manda et al., ; Ng'ombe et al., ; Teklewold et al., ). Moreover, there is little evidence on the poverty impacts of MATs using panel data.…”

Using plot level panel data and multinomial endogenous switching regression, this article analyzes the adoption and welfare impacts of multiple agricultural technologies in eastern Zambia. We adapt a multinomial endogenous switching/treatment effect regression framework to correct for selection bias and endogeneity originating from both observed and unobserved heterogeneity. Results indicate that joint adoption of multiple agricultural technologies had greater impacts on crop yields, household incomes, and poverty than the adoption of individual components of the technology package. Our findings suggest that efforts aimed at raising household incomes and reducing poverty should focus on promoting the adoption of multiple agricultural technologies through provision of improved support services such as extension and input supply.JEL classifications: C34, O12, O33, Q12, Q16, Q18
