22 pages, Commercialisation of smallholder agriculture is important for rural economic growth. While previous studies have analysed effects of commercialisation on productivity and income, implications for farm household nutrition have received much less attention. We evaluate the effects of commercialisation on household food security and dietary quality with a special focus on calorie and micronutrient consumption. We also examine transmission channels by looking at the role of income, gender, and possible substitution effects between the consumption of own-produced and purchased foods. The analysis uses survey data from farm households in Kenya and a control function approach. Generalised propensity scores are employed to estimate continuous treatment effects. Commercialisation significantly improves food security and dietary quality in terms of calorie, zinc and iron consumption. For vitamin A, effects are insignificant. Commercialisation contributes to higher incomes and increased nutrients from purchased foods, but it does not reduce the consumption of nutrients from own-produced foods. Enhancing market access is important not only for rural economic growth, but also for making smallholder agriculture more nutrition-sensitive.
14 pages., For improved rice production, farmers need access to timely and relevant knowledge at each stage of the rice-cropping calendar. To understand how farmers involve themselves in acquiring and sharing agricultural knowledge, this study investigates how knowledge management best practices can be enhanced among rice farmers in selected rural areas of Tanzania. Data were collected from 226 rice farmers in three districts (Kilombero, Kilosa and Mvomero) of the Morogoro region in Tanzania. Findings from structured questionnaires and focused group discussion indicate that rice farmers accessed, shared and used agricultural knowledge. It was found that individual, institutional and knowledge factors influence the performance of agricultural knowledge management activities. For enhancing effective agricultural knowledge management, it is important to take into consideration the knowledge management best practices, which include developing effective knowledge infrastructure, involving different stakeholders and using appropriate information and communications technology tools in enhancing access to knowledge. It is concluded that effective knowledge management activities increase the level of adoption of agricultural innovations. It is recommended that the proposed agricultural knowledge management best practices be adapted for improving rice production.
