Enset Xanthomonas wilt (EXW) was first reported in 1939 and continues to threaten the sustainability of farming systems in south and southwestern parts of Ethiopia. The present study was conducted in the central zones of southern Ethiopia to assess farmers’ knowledge and perception about EXW, its etiology and mode of transmission, and its implications for […]

“In his 2004 article “What is a case study and what is it good for?,” political scientist John Gerring noted that, though case studies continue to be used widely, researchers “have difficulty articulating what it is that they are doing, methodologically speaking. The case study survives in a curious methodological limbo” (p. 341, emphasis ours). […]
In this short video, Ric Coe introduces the concepts of options by context interactions by describing the more standard “genotype by environment” interactions that plant breeders use, and then generalising the idea.
This video discusses some of the issues surrounding the design of experiments when considering options by context interactions, including how to decide what ‘options’ to test, and the contexts in which to test them.
Communication is vital when conducting experiments with farmers. This video discusses some of the issues of how, why and particularly what to communicate when working with farmers. We also make the case for a detailed written protocol to communicate the details of the design to yourself and others. Written by Ric Coe Designed by Emma […]
Replication is often a point of confusion for researchers. Often, researchers conducting on-farm trials will simply say “the farms / farmers are my replicates” and leave it at that. This video discusses why this is not a good idea, and why you need to think more carefully about where your replicates are in your design […]
This video gives some examples of how to look at data from on-farm trials in a slightly different way, enabling you to get more information from the data. We also discuss how to design your trial to make it as easy as possible to get useful and relevant information from the results. Written by Ric […]
Assessing how livelihoods in rural sub-Saharan Africa might change given future trends in socio-economic and biophysical conditions helps to identify and direct effective efforts towards poverty reduction. Based on existing literature, hypothetical changes in farmer practices and policy interventions were described and used to build five contrasting scenarios towards the year 2027.
The McKnight Foundation commissioned a series of case studies to assess the approach of its Collaborative Crop Research Program (CCRP) as evidenced by the accomplishments and contributions of selected CCRP‐funded projects. The case study presented here focused on three CCRP‐funded projects targeting the breeding, production, and utilization of orange‐fleshed sweet potatoes (OFSP) in Uganda, Kenya, […]

The large diversity of farms and farming systems in sub-Saharan Africa calls for agricultural improvement options that are adapted to the context in which smallholder farmers operate. The socio-ecological niche concept incorporates the agro-ecological, socio-cultural, economic and institutional dimensions and the multiple levels of this context in order to identify which options fit best. In […]
