  abstract = {{W}ild genetic resources and their ability to adapt to environmental change are critically important in light of the projected climate change, while constituting the foundation of agricultural sustainability. {T}o address the expected negative effects of climate change on {R}obusta coffee trees ({C}offea canephora), collecting missions were conducted to explore its current native distribution in {U}ganda over a broad climatic range. {W}ild material from seven forests could thus be collected. {W}e used 19 microsatellite ({SSR}) markers to assess genetic diversity and structure of this material as well as material from two ex-situ collections and a feral population. {T}he {U}gandan {C}. canephora diversity was then positioned relative to the species' global diversity structure. {T}wenty-two climatic variables were used to explore variations in climatic zones across the sampled forests. {O}verall, {U}ganda's native {C}. canephora diversity differs from other known genetic groups of this species. {I}n northwestern ({NW}) {U}ganda, four distinct genetic clusters were distinguished being from {Z}oka, {B}udongo, {I}twara and {K}ibale forests {A} large southern-central ({SC}) cluster included {M}alabigambo, {M}abira, and {K}alangala forest accessions, as well as feral and cultivated accessions, suggesting similarity in genetic origin and strong gene flow between wild and cultivated compartments. {W}e also confirmed the introduction of {C}ongolese varieties into the {SC} region where most {R}obusta coffee production takes place. {I}dentified populations occurred in divergent environmental conditions and 12 environmental variables significantly explained 16.3% of the total allelic variation across populations. {T}he substantial genetic variation within and between {U}gandan populations with different climatic envelopes might contain adaptive diversity to cope with climate change. {T}he accessions that we collected have substantially enriched the diversity hosted in the {U}gandan collections and thus contribute to ex situ conservation of this vital genetic resource. {H}owever, there is an urgent need to develop strategies to enhance complementary in-situ conservation of {C}offea canephora in native forests in northwestern {U}ganda.},
