Most micro-level studies on the impact of agricultural technologies build on cross-section data, which can lead to unreliable impact estimates. Here, we use panel data covering two time periods to estimate the impact of tissue culture (TC) banana technology in the Kenyan small farm sector. TC banana is an interesting case, because previous impact studies showed mixed results. We combine propensity score matching with a difference-in-difference estimator to control for selection bias and account for temporal impact variability.
Este trabajo busca evaluar el impacto de las Escuelas de Campo en familias y fincas cacaoteras de Upala y Talamanca (Costa Rica).
La perspectiva sistémica ha sido aplicada extensamente al estudio de la innovación, dada la existencia de múltiples agentes heterogéneos cuya interacción permite la generación, difusión y uso del conocimiento. Sin embargo, tal interacción presenta dificultades por las brechas existentes entre los agentes, siendo los intermediarios los responsables de construir puentes y facilitar la vinculación.
Providing smallholder farmers with support through conventional government extension approaches is challenging as the number of extension agents is decreasing. At the same time, new information and communication technologies (ICTs), such as short message services (SMS) sent via mobile phones, show considerable promise to complement existing extension services. In the UP-scaling Technology in Agriculture through Knowledge and Extension (UPTAKE) Project, ICTs were used to create awareness and increase uptake and adoption of agricultural innovations by maize farmers in Tanzania.
This chapter examines empirical results of evaluation reports from the AfrED database in order to unpack the relationship between the demand for evaluations and the capacities needed to meet that demand. The analysis further explores ways in which current M&E training and education provision can be enhanced to respond to capacity development needs. In achieving its objectives, the chapter also draws evidence from a secondary analysis of the results of a survey of evaluation practitioners’ perceptions of ECD challenges in the sector.
The importance of extension services in helping smallholder farmers to address the many challenges of agricultural production cannot be over-emphasized. However, relatively few studies have been conducted that investigate how the capacities of agricultural extension agents can be built to more effectively assist smallholder farmers in managing climate risks and impacts. As climate change is a key threat to smallholder food production, addressing this issue is increasingly important.
This report presents the impact and lessons learned from the Andhra Pradesh Drought Adaptation Initiative (APDAI). The APDAI was implemented as a package of pilot activities in two dryland districts in Andhra Pradesh (Anantapur and Mahbubnagar) with the aim of developing and testing approaches for natural resource-based economic activities to better respond to current climate variability and long-term consequences of climate change. The report discusses how innovations are being scaled up through integration into regular government programs for greater outreach.
This brief discusses the benefits of innovation platforms in dealing with natural resource management issues.
This brief is part of the series of ‘practice briefs’ intended to help guide agricultural research practitioners who seek to support and implement innovation platforms. A contribution to the CGIAR Humidtropics research program, the development of the briefs was led by the International Livestock Research Institute; they draw on experiences of the CGIAR Challenge Program on Water and Food, several CGIAR centres and partner organizations.
This note is part of the Global Good Practices Initiative, which aims to provide information about extension approaches and methods in easy-to-understand formats. It focuses on Innovation Platforms, examining in particular two case studies: the Ghana Oil Palm platform and the Research Into Use (RIU) programme in Tanzania.
C’est en 1954 que les paysans de la Commune rurale de l’Imanan, située dans l’Ouest du Niger, ont commencé la culture de pomme de terre. Partie d’une simple culture d’appoint associée à d’autres spéculations, la production de pomme de terre fait maintenant partie intégrante des systèmes de productions locaux. C’est la principale stratégie adaptative des paysans pour faire face aux crises alimentaires.
