The magnitude 7 earthquake that struck Haiti on 12th January 2010 devastated large areas of the capital city of Port-Au-Prince and surrounding communes. Around 222,570 people were killed and a further 300,572 injured. Displacement peaked at close to 2.3 million people, including 302,000 children. At least 188,383 houses were badly damaged and 105,000 were destroyed by the earthquake. In slums, such as Grand Ravine, Martissant, the impact of the earthquake was aggravated by decades of political instability, chronic underinvestment in infrastructures and poor enforcement of urban regulation.In partnership with Concern Worldwide, Architecture for Humanity (AfH) and MSAADA Architects, CRS delivered programming for creating decent and secure living conditions for residents of Grand Ravine, Portau-Prince, Haiti through comprehensive strategies for the improvement of infrastructure, access to secure housing, provision of basic services, revitalization of the economy and reinforcement of owner driven solutions.
