Sustainable intensification of smallholder farming is a serious option for satisfying 2050 global cereal requirements and alleviating persistent poverty. That option seems far off for Sub-Sahara Africa (SSA) where technology-driven productivity growth has largely failed. The article revisits this issue from a number of angles: current approaches to enlisting SSA smallholders in agricultural development; the history of the phenomenal productivity growth in the USA, The Netherlands and Green Revolution Asia; and the current framework conditions for SSA productivity growth.

This paper takes the viewpoint of a social scientist and looks at agricultural scientists' pathways for science impact. Awareness of these pathways is increasingly becoming part and parcel of the professionalism of the agricultural scientist, now that the pressure is on to mobilize smallholders and their productive resources for (global) food security and for reducing persistent rural poverty. Significant new thinking about pathways is emerging and it is useful to present some of this, even if it is not cut-and-dried.

The Raya valley in Tigray, where Alamata Woreda is located, has suitable climate and rich water resources, among others, to grow various tropical fruits. Development of fruits only started a few years ago (1996) with the Raya Valley Development Project and the OoARD (Office of Agriculture and Rural Development), mostly focusing on papaya. A participatory rural appraisal (PRA) study conducted by the Woreda stakeholders identified tropical fruits as a potential marketable commodity in 2005.

Bure district has a diverse ago-ecology, different soil types, a relatively long rainy season and a number of rivers and streams for irrigation. Therefore, it has suitable tract of land to grow temperate, subtropical and tropical fruit crops. In 2007, fruits were identified as a potential marketable commodity by the stakeholders participating in the IPMS project. They diagnosed that farmers had limited orchard management knowledge and skill and were growing locally available less productive and low quality fruit varieties.

Ethiopia has a diverse agro-ecology and sufficient surface and ground water resources, suitable for growing various temperate and tropical fruits. Although various tropical and temperate fruits are grown in the lowland/midland and highland agro-ecologies, the area coverage is very limited. For example, banana export increased from less than 5,000 tons in 1961 to 60,000 tons in 1972, but in 2003 declined to about 1,300 tons worth less than USD 350,000.

With irrigated vegetables development, interventions on the uses of improved inputs such as water lifting devices; varieties; on-farm water, nutrient and pest management, and access to credit and market information were introduced in Atsbi-Womberta district, Ethiopia. Besides, skill and uptake capacity of vegetable growers, extension service providers and vegetable traders were improved accordingly.

Graduate programs in agriculture and allied disciplines in Ethiopia are expected to make concrete contribution to market-oriented development of smallholder agriculture. This, among others, calls for realignment and engagement of the programs with smallholder farmers and, value chain, R&D and policy actors. No panacea exists, however, as to how to ensure effective linkages, and thereby responsiveness. Lessons from initiatives on the ground in the country and beyond is thus crucial to inform the development of appropriate policy and innovative strategy.

Strengthening the capacity of farmer training centers (FTCs) in Ethiopia and enhancing FTC‐based training and knowledge services is important to leverage and optimize potential contributions of FTCs to facilitating market‐led and knowledge‐based agricultural transformation.

The LIVES project works to increase adoption of value chain interventions through use of improved knowledge and capacity by value chain actors and service providers. Knowledge management and capacity development are important components of the project to fill gaps in knowledge and capacity of value chain actors and service providers. Capacity is defined as the capabilities (knowledge, skills, experience, values, motivations, organizational processes, and linkages) that determine how well value chain actors and service providers utilize resources, market opportunities, and relationships.
