This discussion allowed participants to analyse the infrastructural weaknesses in their cities that are becoming increasingly problematic given the changing climate. Experts from African, Asian and Latin American cities considered why infrastructure is not meeting the needs of city dwellers, and what might be done to encourage investments in infrastructure. Interviews with Latin American experts from Mexico City, Mexico, and Lima, Peru, highlighted successful strategies for improving wastewater management. Key factors to success in these cases included a good return on public spending (Mexico) and an integrated approach (Peru). Participants from Africa and Asia also shared successful examples from their cities.
