The UN Technology Bank for Least Developed Countries is a new global organisation, dedicated to enhancing the contribution of science, technology and innovation (#STI) for sustainable development in the world’s 46 least developed countries (#LDCs). The least developed countries are low-income countries confronting severe structural impediments to sustainable development. They are highly vulnerable to economic and environmental shocks and have low levels of human assets. The UN Technology Bank supports national and regional technological efforts in the least developed countries, reinforcing partnerships across sectors and helping nations identify and use appropriate technologies to transform their economies and improve livelihoods.
