The intensity of adoption of conservation agriculture by smallholder farmers in Zimbabwe

ABSTRACT This article assesses the intensity of technology adoption of conservation agriculture (CA) techniques by smallholder farmers in Zimbabwe. It seeks to understand the drivers of CA adoption intensity in terms of the number of practices implemented using count data analysis. On average, the farmers in our sample adopt five out of eight possible CA practices while only 7.4% use all eight practices in any one year. Practices such as digging planting basins (81.9%), applying manure (73.2%) and timely post-planting weeding (70.1%) are relatively popular, while adoption of crop rotation (22.8%) is comparatively rare. Productivity is positively correlated to the number of techniques used. Farmers adopting all the CA practices are the most productive, with an estimated maize yield of 2.50 tons/ha, compared with a yield of less than 1 tons/ha for those using three techniques or fewer. Results from a Poisson regression indicate that education, agro-ecology, non-governmental input support and extension support have a significant impact on adoption intensity. Subsidised inputs increase the number of components used, although access to those inputs was uneven across regions of Zimbabwe. Further, the number of CA components used in the previous season positively impacts current season adoption intensity, implying that promotions of CA technologies do have a persistent effect, even after those promotions end.

Nutrition education, farm production diversity, and commercialization on household and individual dietary diversity in Zimbabwe

Background Nutrition education is crucial for improved nutrition outcomes. However, there are no studies to the best of our knowledge that have jointly analysed the roles of nutrition education, farm production diversity and commercialization on household, women and child dietary diversity. Objective This article jointly analyses the role of nutrition education, farm production diversity and commercialization on household, women and children dietary diversity in Zimbabwe. In addition, we analyze separately the roles of crop and livestock diversity and individual agricultural practices on dietary diversity. Design Data were collected from 2,815 households randomly selected in eight districts. Negative binomial regression was used for model estimations. Results Nutrition education increased household, women, and child dietary diversity by 3, 9 and 24%, respectively. Farm production diversity had a strong and positive association with household and women dietary diversity. Crop diversification led to a 4 and 5% increase in household and women dietary diversity, respectively. Furthermore, livestock diversification and market participation were positively associated with household, women, and children dietary diversity. The cultivation of pulses and fruits increased household, women, and children dietary diversity. Vegetable production and goat rearing increased household and women dietary diversity. Conclusions Nutrition education and improving access to markets are promising strategies to improve dietary diversity at both household and individual level. Results demonstrate the value of promoting nutrition education; farm production diversity; small livestock; pulses, vegetables and fruits; crop-livestock integration; and market access for improved nutrition.
