Managing the ability of agriculture to meet rising global demand and to respond to the changes and opportunities will require good policy, sustained investments, and innovation - not business as usual. Investments in public Research and Development, extension, education, and their links with one another have elicited high returns and pro-poor growth, but these investments alone will not elicit innovation at the pace or on the scale required by the intensifying and proliferating challenges confronting agriculture. Experience indicates that aside from a strong capacity in Research and Development, the ability to innovate is often related to collective action, coordination, the exchange of knowledge among diverse actors, the incentives and resources available to form partnerships and develop businesses, and conditions that make it possible for farmers or entrepreneurs to use the innovations. While consensus is developing about what is meant by 'innovation' and 'innovation system', no detailed blueprint exists for making agricultural innovation happen at a given time, in a given place, for a given result. The AIS approach that looks at these multiple conditions and relationships that promote innovation in agriculture, has however moved from a concept to a sub-discipline with principles of analysis and action. AIS investments must be specific to the context, responding to the stage of development in a particular country and agricultural sector, especially the AIS. This sourcebook contributes to identifying, designing, and implementing the investments, approaches, and complementary interventions that appear most likely to strengthen AIS and to promote agricultural innovation and equitable growth. It emphasizes the lessons learned, benefits and impacts, implementation issues, and prospects for replicating or expanding successful practices. The information in this sourcebook derives from approaches that have been tested at different scales in different contexts. It reflects the experiences and evolving understanding of numerous individuals and organizations concerned with agricultural innovation, including the World Bank. This information is targeted to the key operational staff in international and regional development agencies and national governments who design and implement lending projects and to the practitioners who design thematic programs and technical assistance packages. The sourcebook can also be an important resource for the research community and nongovernmental organizations (NGOs).

Whereas there is plenty of work looking at macroeconomic effect of public spending on growth and poverty in Africa as well as studies of the impact of spending or investment in one economic sector on outcomes in that sector or on broader welfare measures, this book fills a much needed gap in the research looking how the composition of public spending affects key development outcomes in the region. The book brings together recent analysis on the trends in, and returns to, public spending for agricultural growth and rural development in Africa. Case studies of selected African countries provide insights on the contributions of different types of public expenditures for poverty, growth and welfare outcomes, as well as insights into the constraints in gaining development mileage from investments in the agricultural sector.

This book investigates the interactions between different shifts in innovation models. It underlines ecological conditions and production intensification in the agriculture sector. In total six innovation processes were analyzed in different countries such as Burkina Faso, Cameroon, Haiti, Madagascar and Senegal. The similarities between these case studies are that they all demonstrate that sustainable and sufficient network between actors of the innovation are particularly useful for the development of agricultural innovation systems. The different papers demonstrate that there is a need for more commitment of public policy in innovation processes.
