This paper asks: What have been the impacts of farmer-or community-led (informal) processes of research and development in agriculture and natural resource management in terms of food security, ecological sustainability, economic empowerment, gender relations, local capacity to innovate and influence on formal agricultural research and development institutions? An innovative conceptual framework was applied to a diverse set of farmer-led research initiatives in countries in Africa, Asia and Latin America to explore approaches, outcomes and impacts of informal agricultural research and development (ARD) facilitated by civil society organisations. Findings include the following: locally appropriate technical innovations emerging from these processes are readily taken up by other farmers; the most common channels of dissemination are farmer to farmer through informal networks and spaces created for farmer-researchers and other farmers to meet and exchange, such as innovation fairs; livelihood impacts are broad and substantial; local capacity to innovate is strengthened and institutionalisation through the formal sector has been limited. Lessons are drawn for future partnerships in promoting and supporting farmer-led research involving formal and informal ARD actors working with smallholder communities.

Farmers' innovation and selection of barley varieties were studied in the Tigray Region in northern Ethiopia. Two districts each in the central and southern zones and three districts in the eastern zone of Tigray were randomly selected for this study, which sought to understand the current status of local barley varieties and to measure their relative preference by farmers. Household surveys were conducted covering 240 households to elicit farmers' views on the values, constraints, and opportunities of growing local varieties of barley. This was supported by focus-group and informal discussions with elders, key informants, and women's groups. Case studies were made of local farmers whom the community recognized as barley breeders. Twenty-four barley varieties and their major descriptors were recorded. Seed and varietal-selection criteria depended on the environmental and varietal characteristics. Investigation of intrahousehold decision making indicated that, while men tended to decide on the type of variety to grow, seed storage and processing were exclusively the responsibility of women. Farmers undertook preharvest and postharvest selection, giving emphasis mainly to earliness and spike characteristics. The distinct varietal-selection and seed-renewal procedures revealed their potential for use in further plant breeding. The case-study analysis of farmer-developed varieties provided knowledge that, if combined with scientists' knowledge, could lead to identification and development of valuable cultivars with a wide potential for use in semiarid areas of Tigray and other parts of Ethiopia.

Within the context of the FP7 JOLISAA project (JOint Learning in and about Innovation Systems in African Agriculture), an inventory of agricultural innovation experiences was developed in three African countries: Kenya, South Africa and Benin. The main objective was to assess a broad diversity of multi-stakeholder agricultural innovation processes involving smallholders. National teams used literature searches and interactions with a range of institutions and networks engaged in agricultural innovation to identify cases. Interviews with resource persons and field visits were also conducted to supplement the available / accessible documentation. The inventory was made according to a common analytical framework and guidelines inspired by the Innovation System perspective to allow for an analysis across cases and countries. The completed inventory includes 57 documented cases, covering a wide diversity of experiences, in terms of types, domains, scales and timelines of innovation. The 57 cases confirm previously documented features, such as the diversity of stakeholders involved in innovation, the diversity of innovation triggers, or also the frequent occurence of market driven innovation. It also illustrates more original features: the typically long time frames of innovation processes; the common occurrence of "innovation bundles" (a combination over time of technological, social and/or institutional innovations); and an often close relationship between innovation and externally-funded projects. National teams faced several challenges during the inventory process, including a common understanding and consistent use of key innovation-related concepts, and a difficult access to relevant information related partly to restrictions put by several case holders on sharing openly their experience. Out of the inventory, JOLISAA has selected thirteen cases which will undergo a subsequent phase of collaborative assessment. The assessment will strive to assess issues the inventory could not tackle, such as the actual roles and contributions of the various stakeholders, the dynamics of the innovation process, and the influence of the enabling environment on the innovation process and outcome.
