Research-development partnerships for scaling complex innovation: Lessons from the Farmer Business School in IFAD-supported loan-grant collaborations in Asia por Prain, Gordon, Wheatly, C., Odsey, C., Verzola, L., Bertuso, A., Roa, J., Naziri, D.

“…Responding to the main research question about the drivers of partnership dynamics that contribute to scaling, the paper examines the partnerships in terms of six drivers which derived both from the literature and also from the empirical evidence presented in the study. The drivers include two dimensions of “fit”, one about the convergence of research expertise and development demand, the other about the systematic integration of the innovation with different elements of the development actions. …”

How relative poverty influences responses to social protection programmes: Evidence from Pakistan por Kosec, Katrina, Mo, Cecilia Hyunjung

“…Evans et al. (2019) show that they can increase trust in leaders and perceptions of leaders’ responsiveness and honesty among recipients. But the empirical evidence is mixed, and other studies show that this does not occur consistently (Freeland 2007, Ellis and Faricy 2011, Zucco 2013). …”

Climate change and ecological intensification of agriculture in sub-Saharan Africa – A systems approach to predict maize yield under push-pull technology por Alexandridis, Nikolaos, Feit, Benjamin, Kihara, Job, Luttermoser, Tim, May, Wilhelm, Midega, Charles, Öborn, Ingrid, Poveda, Katja, Sileshi, Gudeta W., Zewdie, Beyene, Clough, Yann, Jonsson, Mattias

“…Our review suggests variable impacts of climate change on PPT components in SSA by the end of the 21st century, including reduced soil fertility, increased weed and arthropod pest pressure and increased prevalence of crop diseases, but also increased biological control by pests' natural enemies. Extrapolating empirical evidence of climate effects to predict responses to projected climate conditions is mainly limited by a lack of mechanistic understanding regarding single and interactive effects of climate variables on PPT components. …”

Pests in plantation forests: Challenging traditional productive paradigms in the Southern Cone of America por Villacide, Jose Maria, Fuentealba, Alvaro

“…In this context, forest diversification, through mixed-species plantations and increased landscape heterogeneity, has emerged as a promising approach to enhance ecological resilience and reduce pest impacts. Although empirical evidence from the region remains limited, studies suggest that greater tree diversity can reduce pest incidence by hindering host detection and promoting more effective natural enemy communities. …”
