LAC Cities Challenge: agenda and technical documents. The LAC Cities Challenge, organized by the IDB Cities Network, seeks to support the cities of Latin America and the Caribbean in the preparation of innovative urban regeneration projects, to promote the participation of the private sector and to be implemented through local economic development agencies. In the first phase, the eight winning cities will have the opportunity to travel to New York, Philadelphia and Washington, D.C. to know international experiences that serve as a reference. https://www.iadb.org/es/desarrollo-urbano-y-vivienda/lac-cities-challenge-proyectos-innovadores-de-regeneracion-urbana
