In sub-Saharan Africa, there is increasing interest for the adaptation and use of the innovation systems approach to advance learning and development in the Agricultural Research and Development (ARD) sector. This crave is constrained by unavailability of a proven blue print that describe the paradigm shift from the linear approach and how such could function under different socio-economic, cultural and political climate.

These notes summarise reflections on local innovation and participatory innovation development that took place within the PROLINNOVA International Support Team (IST), based on observations and discussions with network partners during advisory visits and international workshops.

This article describes one of the local innovations identified by the Northern Typical Highlands (NTH) platform of Prolinnova-Ethiopia: an intricate system of harvesting water from waterlogged land to allow cultivation in the long wet season, coupled with storage of this harvested water to use for supplementary irrigation in the following dry season.

In this paper the authors present the development of an analytical framework to study agricultural innovation systems. They divide the agricultural sector into four levels and expand the innovation system approach to study innovation processes.

In order to determine the factors affecting the adoption of agricultural innovations, 169 farmers were reviewed in 7 counties that may represent Erzurum province in terms of social, economic and cultural aspects. The data were analyzed in LIMDEP software using logistic regression method and the results were presented in tables. The innovations examined in the study were adoption of artificial insemination, membership to cooperative, having automatic waterer in stables and making use of incentives for agricultural production.

This paper briefly analyse the genesis, development and change in public sector-led extension approaches in India showing its temporal pattern, emerging innovations in extension approaches and the way forward. It discusses decentralized, community based, pluralistic extension approaches and their opportunities as well as limitations in changing agricultural and natural resources scenario.

Zimbabwe has a pluralistic agricultural extension system. In addition to the public extension service, donors contract private service providers to deliver extension services in specific project areas. This study assesses the impact of an outsourced extension service on rural households in the Mutasa district of Zimbabwe’s Manicaland Province, and examines the financial cost and benefit of this service. The extension service was delivered by a local agribusiness firm and funded by USAID. The study analyses survey data gathered from 94 client and 90 non-client rural households.

In order to facilitate Participatory Technology Development (PTD) in African agriculture, extensionists and scientists must collaborate with local innovators to optimise (where necessary) and disseminate their innovations. This literature review proposes a conceptual model for PTD in which technology is developed in the context of an adoption cycle. Building on an innovation-decision approach, the characteristics of innovations that achieve widespread uptake are identified.

The aim of this study was to explore the interactions that exist among agricultural stakeholders in the southwestern highlands of Uganda as a way of identifying opportunities and gaps for operation of Innovation Platforms (IPs) under the proof of concept of Integrated Agricultural Research for Development (IAR4D) research project.

Innovation system approach offers an holistic, multidisciplinary and comprehensive framework for analyzing innovation process, the roles of science and technology actors and their interactions, emphazing on wider stakeholder participation, linkages and institutional context of innovation and processes. This paper was aimed to: 1. review the concept of innovation system; 2. appraise the application to agriculture and its relevance and 3. analyze the policy implications for agricultural extension delivery in Nigeria.
