Considers the potential contribution of traditional construction techniques and materials to rebuilding in Port-au-Prince and other areas in Haiti that were devastated by the 2010 earthquake. Based on different examples of housing that collapsed or was damaged by the earthquake, it shows how traditional construction systems often demonstrated better resilience to earthquakes than buildings constructed with modern materials.
Landslides pose a serious physical and environmental threat to vulnerable communities living in areas of unplanned housing on steep slopes in the Caribbean. Some of these communities have, in the past, had to be relocated, at costs of millions of dollars, because of major slides triggered by tropical storm rainfall. Even so, evidence shows that: (1) risk reduction is a marginal activity; (2) there has been minimal uptake of hazard maps and vulnerability assessments and (3) there is little on-the-ground delivery of construction for risk reduction. This article directly addresses these issues by developing a low-cost approach to the identification of the potential pore pressure changes that trigger such slides.
