LEVELS OF MITIGATION
HOW CAN EXISTING VILLAGES IN FIJI BE RESTRUCTURED TO BECOME CYCLONE-RESISTANT AT LITTLE TO NO EXTRA COST TO THE COMMUNITY? EXTERNAL LAYER OF VEGETATION
The existing layout of Vunisavi has not been designed to cope with the increasing cyclone risks. Although surrounded by dense vegetation on three sides, the fourth side is entirely exposed to coastal threats. Q: HOW DO WE CREATE A PROTECTIVE BOUNDARY BETWEEN THE SEA AND THE VILLAGE WITHOUT DESTROYING THE CULTURAL AND PRACTICAL SIGNIFICANCE OF ITS PROXIMITY?
Identifying zones for different uses can help to implement varying levels of disaster mitigation. To ensure this is successful, a thorough site survey should be undertaken to identify the best strategies for the site. These strategies are likely to vary depending on location, available land and community needs.
Intentional landscape patterns can help to reduce the speed of any oncoming waves. S-shaped plots and irregular junctions are much more reslient than a standard linear design.
Below indicates some of the questions that would need to be investigated within this survey:
OVERALL VILLAGE DESIGN COMMUNITY CENTRE
OPEN SPACE
BUSH KITCHEN
1) Community build fund - central space allocated to the ‘heart’ of the community and built by the collective
2) Locally allocated plots for subsistence farming. Although within the circular zones, these plots should be organic for protective measures.
Q: WHAT COMMUNITY FACILITIES ARE IMPORTANT TO THE VILLAGE? Q: CAN THIS FACILITY BE USED AS A ‘SITE-OFFICE’ FOR FURTHER DEVELOPMENT AND RESEARCH?
3) outer layer of houses that can be integrated with farming plots for maximum protection. Q: HOW WOULD THIS PROCESS OF BUILDING WORK LOGISTICALLY? THE SURVEY WOULD NEED TO DETERMINE APPROPRIATE LOCATIONS FOR REBUILDING E.G. WHERE SOIL IS STILL INTACT.
Q: WHAT PRODUCE WOULD THE COMMUNITY GROW? HOW CAN THESE BE INTERCROPPED FOR MAXIMUM PROTECTION?
DETAILS AND SYSTEMS ENVELOPE SKETCH DETAIL -
AVERAGE DAY - Walls can fold out to provide canopies, decks and ramps.
Charcoal, held together with mesh, is placed between a double timber stud wall. A rainwater pipe collects any water run-off from the sloped roof and slowly filters it through tiny holes into the charcoal. As the water evaporates into the warm air, it cools the temperature inside. If feasible, this system could allow Fijians to preserve their fresh produce for longer, potentially reducing reliance on imported, processed foods.
