This document discusses the evolution of global cluster initiatives. It notes that interest in clusters as drivers of economic growth and innovation has increased significantly since the 1990s. Many international organizations like the World Bank, UNIDO, USAID, and IDB have launched cluster development programs in developing countries since the mid-1990s. The number of cluster initiatives started growing rapidly in the early 2000s. By 2003, over 500 cluster initiatives had been identified globally. India also started cluster development programs in 2002, focusing on traditional manufacturing sectors. Overall, cluster-based approaches have now become widely used by governments and organizations around the world to promote local economic development.
