Shea  was expanded through human intervention and is linked to human migration; fruit traits such as fruit size and shape, pulp sweetness and kernel fat content are determined both by temperature and rainfall, as well as human selection for preferred traits . There is limited and conflicting evidence of the impacts of climatic conditions and future projected climate variations on V. paradoxa . Mixed evidence of the impact of climate and rainfall on fruit production and timing is reported . Fruit production was negatively correlated with mean annual temperature and positively correlated with annual rainfall .
