Disaster Resistant Caracas:Urban Planning Student Studio Workshop on Urban Risk Management for Natural Disasters Istanbul, October 25-26, 2001 Columbia University School of Architecture Planning and Preservation Lamont-Doherty Earth Observatory Disaster Resistant Caracas URBAN PLANNING STUDIO Spring 2001
The Caracas Pilot • Disaster Resistant Caracas Studio • Development of methodological approach to multi-disciplinary planning and design • A prototype Inter-Departmental study executed by Master and Doctoral Students in Urban Planning and Geosciences lead by Geoscience and Urban Planning Faculty team. • Three-month probe highlighted critical issues for disaster resiliency. • Built on continuing 6-year collaboration between IREU and Columbia University on urban problems in Caracas, and the 50-year history of global earth science research of Lamont-Doherty. • Seed funded by CHRR to promote integrated research.
The Caracas Pilot (cont.) • Achievements • Demonstrated success of integrated methodology • Established local technical and academic collaboration • Developed links to federal and municipal institutions organized around data collection and preliminary analysis • The Caracas Pilot is a preliminary planning study, not a plan. More work has to be done.
Definitions • Sustainability: The balance between current use of available cultural, social, economic, political and natural resources, and future needs. • Disaster Resiliency: The ability to preserve sustainable growth after accounting for the direct and indirect impacts of disasters.
Premise: Disaster Resilience is a characteristic of sustainable societies. • Disaster Resilience will enhance social development. • Disasters highlight social and economic inequities, and affect the poor disproportionately. • Thus, Disaster Resilience is an agent of poverty reduction and social stability. • Disaster Resilience provides an additional incentive for international investment.
The Context • Latin America is experiencing rapid and unplanned urban growth. Proper growth can be channeled to increase prosperity and sustainability. • Latin American cities are centers of education and culture, fueling innovation and creativity. But they are exposed to natural hazards. • Greater Caracas is an example of a regional center where linkages in culture, finance, telecom, media, technology, and natural resource distribution are integrated. Caracas is also exposed to risk.
The Context (Continued) • Building disaster resilient metropolitan areas accomplishes the dual goal of achieving social development and protecting the people and their built environment. • Integrated urban areas will be centers for the application of sustainable development strategies based on science and rational planning.
The Challenge Can planning, science, and political will be combined to produce orderly and equitable urban development?
Three Components of Urban Disaster Resilience • Rational planning process that includes hazard mitigation. • Risk management strategies, including financial, regulatory, and market incentives. • Emergency preparedness and response.
