Technology adoption and household food security among rural households in South Africa: The role of improved maize varieties

This study aimed to assess the impact of adoption of improved maize varieties on household food security among smallholder farmers in KwaZulu-Natal, South Africa. A sample of 415 maize producers was analysed using the propensity score matching method, the treatment effect model and the Tobit selection model. The results were consistent across the models, indicating that improved maize varieties positively increased household food security, and that the impact of adoption differed according to the adoption level and socio-economic characteristics of the farmers. The results showed that an additional 1 ha of land under improved maize varieties increases annual food expenditure per capita levels by over R4000. Female farmers were more likely to adopt improved maize varieties, and spent more to ensure household food security, and benefitted more from adoption, than their male counterparts. The findings suggest that policies that seek to increase the land under improved maize varieties among smallholder farmers, especially female farmers who are the majority of these farmers, can play a significant and positive role in increasing the levels of household food security in South Africa through technological innovations. The study recommends that policy makers should aim to facilitate the dissemination of less costly improved seed varieties, target female farmers, and improve their access to information to improve the adoption of technological innovations and food security among the poor farming households in South Africa.     

Dissemination strategies and the adoption of improved agricultural technologies: The case of improved cassava varieties in Ghana

Cassava (Manihot esculanta Crantz) is an important tropical root crop for food security and national economies in Africa. In Ghana, it is the most important staple food also used in breweries, bakery and confectionery industries. Several high-yielding and disease resistant improved cassava varieties (ICVs) have been released and are being promoted through diverse dissemination channels. Past studies investigate the role of information in the adoption of agricultural technologies without accounting for the diversity in the dissemination strategies. The paper explores the diversity of dissemination strategies in examining the adoption of improved cassava varieties using a sequential mixed-method approach which combines exploratory interviews and focus group discussions with a questionnaire-based quantitative survey and the Cragg's two-part model. The paper uses data collected from 608 farmers randomly selected from major cassava producing communities in the Ashanti and Brong-Ahafo regions in Ghana, West Africa. The results show statistically significant and identical impact of information through demonstrations, distribution of planting materials, farmer-to-farmer and media on the probability of ICV adoption. Other drivers of adoption are the membership of farmers based organizations (FBO), planting of two or more varieties and having large livestock size. However, ICV adoption and intensity was hampered by household size, distances to the nearest tarred road and market, and grey-skin color. These attributes need to be integral of dissemination campaigns for cassava variety adoption.
