Currently, the Peruvian capital, Lima, a fast-growing metropolitan area with a population of 9.8 million, has no urban development plan. The last active plan expired in 2010. In 2014, after four years of work, the previous mayoral administration, working in cooperation with many institutions and international organizations, proposed a new metropolitan plan. For many different reasons, including political considerations but also social and economic factors, the plan was not approved. As a result, there is currently no plan guiding or organizing the rapid urban transformations of Lima’s large coastal territory, a semi-desert region dependent on the snows of the Andes for its supply of fresh water.
