From the 1950s to the late 1980s, the politics and economies of foreign aid — instigated by both the ‘capitalist West’ as well as the ‘communist East’ — gave rise to a whole infrastructure destined to assist the progress of ‘developing countries’ on their ‘path to development’. The various North-South exchanges that took place in the name of ‘development’ have left a deep imprint on the geopolitical landscape of postcolonial Africa, Asia, and Latin America. Largely instituted through bilateral relations between individual states, these ‘aid’ initiatives involved not only financial and material resources but also various forms of knowledge and expertise; as such, the modalities of this global, foreign aid-funded infrastructure boosted the creation and reinforcement of all sorts of institutional actors to efficiently exchange knowledge — largely through training courses, educational programs and/or research projects. In the light of widespread rural migration and intensive, rapid urbanization processes, expertise on the built environment was a particularly salient form of knowledge to the aims of foreign aid. Hence, architecture, urbanism and planning were no strangers to an emerging foreign aid-funded knowledge economy — a context in which the production and circulation of knowledge were intimately tied to the political-economic value attributed to them by foreign aid diplomacy.
