This is a chapter of the book Innovation platforms for agricultural development edited by Iddo Dror, Jean-Joseph Cadilhon, Marc Schut, Michael Misiko and Shreya Maheshwari.

This book summarizes the achievements as well as some of the challenges faced while implementing integrated systems research to support the sustainable development of smallholder farming in the uplands of the Mekong region.

An innovation platform is a space for learning and change. It is a group of individuals (who often represent organizations) with different backgrounds and interests: farmers, traders, food processors, researchers, government officials etc. The members come together to diagnose problems, identify opportunities and find ways to achieve their goals. They may design and implement activities as a platform, or coordinate activities by individual members. This brief explains what innovation platforms are and how they work, and it describes some of their advantages and limitations.

This case study zooms in on multi-stakeholder processes in the East and Central Africa (ECA) Action Area or Flagship that were launched on 20 May 2013 in Bukavu, DR Congo. The ECA Flagship encom-passes the Rwanda, DR Congo, Burundi, Uganda, Kenya and Ethiopia Action Sites. More specifically, the case study describes and reflects upon the first two years of CGIAR Humidtropics in DR Congo. aiming to outline the multi-stakeholder process as it unfolded and highlight lessons that can be learned from this.

Brazilian agriculture is facing another expansion cycle to the Cerrado region, more specific in the Northeast. The first agriculture expansion cycle to the Midwest was in seventies encouraged and developed by Brazilian Government with farmers from southern and southeast Brazil, which were traditional small farmers with some experience, low budget and a remarkable determination. All of these efforts after 20 years resulted in an outstanding development of a part of the country with economy based on agribusiness (soybean, corn, cotton, livestock, poultry, swine, etc.).

Precision agriculture (PA) is growing considerably in Brazil. However, there is a lack of information regarding to PA adoption and use in the country. This study sought to: (i) investigate the perception of growers and service dealership about PA technologies; (ii) identify constraints to PA adoption; (iii) obtain information that might be useful to motivate producers and agronomists to use PA technologies in the crop production systems.

Maize production is of critical importance to smallholder farmers in Ghana. Various factors limit the productivityof smallholder maize farming systems undergirded by the lack of capital for critical investments both at the farmand at national policy levels. Using a value chain approach, this diagnostic study explains how a complex configuration of actor interaction within an institutionally and agro-ecologically challenged value chain leads tothe enduring absence of maize farming credit support.
