Evaluating agricultural weather and climate services in Africa: A learning agenda on climate information services in sub-Saharan Africa
Weather and climate services (WCS) are expected to improve the capacity of Africa’s agricultural sector to manage the risks of climate variability and change. Despite this, a lack of evidence regarding WCS prevents a realistic analysis of whether services are delivering on their potential. This pa...

| description | Weather and climate services (WCS) are expected to improve the capacity of Africa’s agricultural sector to
manage the risks of climate variability and change. Despite this, a lack of evidence regarding WCS prevents
a realistic analysis of whether services are delivering on their potential. This paper reviews 59 studies that
have evaluated outcomes and/or impacts of agricultural WCS in Africa, highlighting areas that have
received relatively more attention, as well as persistent gaps. While the evaluation of WCS outcomes is
relatively straightforward, estimates regarding access and use of these services are uneven (covering a small
number of communities in 22 of 54 African countries) and highly variable (with access ranges from ~2-
86%, depending on the service and the population). Meanwhile, just 16 documents estimate the impact of
WCS with respect to yields and/or income. Developed with a variety of methods, these estimates are also
wide ranging (some users lose, while others experience up to 66% marginal gains) and illustrate how
impact is conditioned on a number of characteristics of the service, the user, and the context in which
both operate. The paper uses lessons developed through this review to develop a “learning agenda,” or
evidence-building roadmap, to establish priorities that can guide future work to generate evidence that can
improve the design, delivery, and impact of agricultural WCS in Africa. Priority learning areas include:
broadening our view of potential users, and uses, of WCS; filling of geographic and demographic gaps; and
quantifying the extent to which “good practice” leads to improved outcomes and impacts. |
