Description In response to the climate change, it is essential to provide smallholder farmers with
improved field crop genotypes that may increase the resilience of their farming system.
This requires a fast turnover of varieties in a system capable of injecting significant
amounts of genetic diversity into productive landscapes. Crop improvement is a pivotal
strategy to cope with and adapt to climate change. Modern breeding may rely on the
genomics revolution to speed up the development of new varieties with adaptive potential.
However, centralized breeding may not adequately address smallholder farmers’ needs
for more locally acclimatized varieties or groups of varieties. This, in turn, constrains
adoption of new varieties that reduces the effectiveness of a resource-intensive breeding
process, an issue that may be overcome with participatory, decentralized approaches.
Whether high-tech centralized breeding or decentralized participatory approaches are
better suited for smallholder farmers in the global South is hotly debated. Sidestepping
any false dichotomies and ideological issues in these debates, this review provides a
perspective on relevant advances in a breeding approach that combines the two
approaches and uses genomics for trait mining from ex situ collections of genetic
materials, participatory multilocation trials and crowdsourced citizen science. It argues
that this new combination of high-tech centralized and participatory decentralized
methods can provide a coherent and effective approach to breeding for climate
adaptation and the present review advocates on a different way forward for the
future research.
