Community mapping for flood resilience
Local community members living in slums create highly accurate maps of the most flood-prone areas of the city by using OpenStreatMap.
EXPLAIN YOUR IDEA
Community mapping for flood resilience is the GIS based system where by local community members living in slums create highly accurate maps of the most flood-prone areas of the city using OpenStreetMap. It is a web system to create a free and open map of the entire world, built entirely by volunteers surveying with GPS, digitizing aerial imagery, and collecting and liberating existing public sources of geographic data. The system produces realistic natural hazard impact scenarios, maps and identifies areas which are mostly vulnerable to flood hazard, which will help for better planning, preparedness and response. The communities in slum are then trained to update the status of their environment even during disasters. The response team can use the information for better allocation of resources which will be needed during response phase. By so doing the level of impacts and disruption will be minimized and hence the level of resilience will be high. The Community mapping gives the opportunities to the community to map(participate) the infrastructures such as roads, drainage, sanitation and water supply by describing their status and identify their levels of vulnerability to hazard and hence being able to develop coping and strategies that will increase the level of resilience in their community.
The community members living in slums will be the first beneficiaries as they will be owning the system. Also the Government will use the data from OpenStreatMap provided by the community as the baseline information during preparedness and response plan. The government can use the data to plan for the resources that will help during disaster
HOW DOES YOUR IDEA TAKE INTO ACCOUNT THE CONTEXT OF URBAN SLUMS AND CLIMATE CHANGE?
The idea takes into account of urban slums and climate change because, the people living in slums are the most who are vulnerable to climate change induced disasters since such as floods, the settlement have insufficient infrastructures such as roads, sanitation, water supply, drainage and solid waste management. The climate change has attributed the flood occurrence in most of the cities but since these areas are more vulnerable they are hit harder. Therefore the idea provides for the sharing of information by using web based system and data is free and can be accessed by any one at any time. The information then can be used to improve the infrastructures and social services.
