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.

Innovation platforms are advocated as a promising way to find solutions to complex problems, such as those in agriculture and natural resource management. As social, economic and environmental problems grow ever more complex, researchers need
to engage more actively with stakeholders such as farmers, development practitioners and policymakers to explore, design and implement solutions. Innovation platforms offer them an opportunity to do so.

Communication is a crucial part of facilitating the process of innovation within an innovation platform. It comprises a broad range of practices and approaches which include information management, publishing, use of information and communication technologies, communication for development, knowledge sharing and knowledge management. Its goal is not just to produce or disseminate more information, but rather to use communication processes to power changes identified by the platform.

Facilitation of innovation is a flexible and adaptive process during which facilitators manage dialogue and stimulate collective problem analysis by multiple stakeholders to overcome challenges or make use of opportunities. The brief describes what facilitation is about, facilitators' functions and roles, skills and attributes, and who facilitates. It is available in Chinese, English, Hindi, Thai and Vietnamese.

The Africa Research In Sustainable Intensification for the Next Generation (Africa RISING) program comprises three research-for-development projects supported by the United States Agency for International Development as part of the U.S. government’s Feed the Future initiative.

The Africa Research in Sustainable Intensification for the Next Generation (Africa RISING) program comprises three research-for-development projects supported by the United States Agency for International Development as part of the U.S. government’s Feed the Future initiative. Through action research and development partnerships, Africa RISING will create opportunities for smallholder farm households to move out of hunger and poverty through sustainably intensified farming systems that improve food, nutrition, and income security, particularly for women and children, and

The workshop was attended by over 50 people including partners from CGIAR centres, Regional Research Institutes and Centres, Universities, woredas and kebeles working with Africa RISING. The workshop discussed the use of different approaches, methods and tools for the efficient and
sustained functioning of innovation platforms (IPs) that could improve research and subsequent scaling up of suitable technologies and value chains to improve livelihoods.

The chapter is a part of the book Innovation platforms for agricultural development edited by Iddo Dror, Jean-Joseph Cadilhon, Marc Schut, Michael Misiko and Shreya Maheshwari. It introduces the background for the setting up of innovation platforms (IPs), initiation and function of the three IPs in Ethiopian highlands, innovation fund to support fodder development, the role of different actors in scaling up, outcomes and impact of the intervention, and lessons learned.
