Context still matters
Nakalembe uses machine learning, computer vision, and deep learning models to map cropland, classify crop types, and estimate yields in Uganda, Kenya, Senegal, and other African nations. But most AI models are trained on European and U.S. data, and are largely useless unless they are adapted for local contexts, she told Rest of World.
“AI systems built in the West often also fail to account for the contexts of the Global South, including high internet costs, limited bandwidth, and a lack of labeled training data,” said Nakalembe, an assistant professor at the University of Maryland, and Africa program director at NASA Harvest, which uses satellite imagery to improve agricultural production.
“If these systems aren’t adapted, they remain irrelevant, potentially deepening existing inequalities in wealth and access to resources, [and] there is a risk that these systems prioritize corporate and company profit over farmers,” she said.
