The Sorsogon City experience in Promoting Risk Resilient Housing

Transcription

1 3 rd Global Forum on Urban Resilience and Adaptation The Sorsogon City experience in Promoting Risk Resilient Housing Bonn, Germany 14 May 2012

2 Challenge: V&AA findings Exposure of houses to climate change impacts as evidenced by: stronger typhoons and storm surge sea level rise flooding landslides increased precipitation and temperature Impacts on the community in terms of: physical structure public health water supply food supply communication and logistics

3 Adaptive Capacity (V&AA findings) limited technical facilities and skills lack of physical structure and machines lack of information management system and center poor disaster preparedness contingency plan strong commitment of the local government

4 Addressing the Issue Adaptation measures should be Participative Systematic Open to the use of alternative materials Cost efficient Community-friendly

5 Addressing the Issue Efforts to address the housing situation: Vulnerability Assessment Information Education Campaign Update of Communication and Warning System Mitigation and adaptation projects in partnership with other agencies/organizations

6 Response: Retrofitting of vulnerable houses (as a quick win) Criteria considered: Could be done immediately, Short implementation period Can be replicated and up-scaled, Benefits can quickly be felt (esp. for sudden onset disasters) Involves the urban poor and community participation With relatively small and affordable financial requirements. Housing Demo Project Retrofitting of 30 units (hotspot villages) Construction of a prototype resilient house

7 Process Formulate guidelines and minimum standards for Resilient Housing and site planning TWG composed of multi-sectoral representatives Housing design and site planning standards based on type of hazard experienced by community National Building Code, BP 220, other standards Develop assessment toolkit for housing vulnerability Set guidelines and criteria for the selection of beneficiary Build capacities of leaders Assess houses with community participation

8 Housing and Basic Services: 8

9 Process Select houses for retrofitting Prepare drawings, specifications, and cost estimates Orient beneficiaries of their roles Retrofit/construct the house Turn-over to beneficiary Benicarlo Torres, one of the beneficiaries in Brgy. Bitan-o, house before, during and after the retrofitting.

10 Technical Elements of a house Roof and roof framing Columns and beams Walls Doors and windows Foundations Factors affecting susceptibility to impacts of CC Geographical location Sorsogon is located in zone where maximum wind velocity reaches to 300 km./hr. at present Topography coastal lines, along rivers, open fields, hilltops, steep slopes Shape of the structure (e.g. irregular shapes are more vulnerable) Stiffness of the structure Weak materials

11 Gains Minimum guidelines and standards for resilient house and site planning developed Development of assessment tool Enhanced knowledge on construction methods Development of IEC materials Active participation of leaders and stakeholders Retrofitted houses Shared experiences of the city Cambodian delegation Provincial planners and institutions Local neighboring cities/municipalities Educators/students

12 Retrofitted houses and IEC materials 12

13 Way forward Institutionalizing the guidelines and standards for a resilient house and site plan City-wide up-scaling of retrofitting vulnerable houses Gradual relocation of high risk communities Continuous awareness climate change campaign Strengthening of the local housing council Implementation of the Local Shelter Plan
