Understanding capacities to scale innovations for sustainable development: a learning journey of scaling partnerships in three parts of Africa por Wigboldus, Seerp, McEwan, M.A., Schagen, Boudy van, Okike, Iheanacho, Mourik, Tom A. van, Rietveld, Anne M., Amole, Tunde A., Asfaw, F., Hundayehu, M.C., Iradukunda, Francois, Kulakow, Peter A., Namanda, S., Suleman, I.

“…It then discusses implications for a partners-in-scaling perspective, the contribution of scaling innovations to sustainable development, the importance of research organisations considering their own capabilities in partnerships for scaling, and the extent to which C4SI was helpful in the three cases—for example, in decision making. The paper concludes that a capacity perspective on the scaling of innovations should be an essential part of a ‘science of scaling’. …”
