Harnessing appropriate technology (AT) is a key strategy for achieving sustainable development by empowering communities, bridging socio-economic divides, and driving inclusive growth. Unlike high-cost, capital-intensive technology, "appropriate technology" is people-centred, environmentally sustainable, and economically viable, enabling communities to gain greater self-reliance and control over their own development. The use of AT boosts productivity and resilience, increases environmental stewardship and fosters grassroots innovation. Through access to hardware and relevant content, ATs such as mobile learning and telehealth can extend services to underserved populations fostering greater inclusion in the digital world. Online financial services, adaptive agriculture, and renewable energy are only some of the areas where AT can strengthen local economies, increase food security, and realize energy access for all. The theme of the 12th ICAT organized by NUST for 2026 offers a platform and opportunity to discuss, debate and envision a sustainable future for Africa.
