Fosie is subjected to flooding. Increasing amount of water is becoming a common problem for the people operating in Fosie. The subject of flooding is also targeted by the city of Malmø, incorporated in superior plans concerning the handling of water for the whole city.

Excess waterlevels are thought to be related to environmental changes of which Fosie has lacking adapting capacity to comprehend. Attributes and spatial identifications of the area should be approached to increase the adapting capacity for water.

water collection area and waterflow; Risebergabäcken, Fosie

The water collection area of Risebergabäcken in Fo-sie is 330 hectars (outlined in blue). According to Malmö city Risebergabäcken has a capacity of 1,5 litres of water per hectar per minute. However, in wet periods the stream reveives over 15 litres per hectar per minute, more than 10 times the estimated capcity!

As a consequence Risebergabäcken can reveive 4500 litres more than its capacity every minute when very wet. Or 270 000 litres every hour.

The fragmented picture of Fosie/Fredriksberg shows that there is a variety of qualities within the area. Looking to Inaki Abalos and his frase “I prefer not to”; how can Fosie be transformed to a “waterresistant” location without loosing its identity?Is it possible to maintain roads, give companies leverage to continue and simultaneously convert the area to a well functioning water retention spot?

- keep exhisting wood/trees can be kept as they retain water and slows evaporation - change parking lots can get permeable surfaces that soaks up water - change exhisting bulidings can be converted to “green roof” buildings - add farmland and left over spaces are suitable for introducing water retention ponds, permaculture farming and human activity

GREEN ROOFS

adding green roofs

20 % of ground covered by flat roof buildings in the water collection area in Fosie a total of 66 hectars rooftops

green roofs can consume 50 % of rainwater, and retain the following 50 %.

in heavy rain 66 hectars receives 990 litres of water every minute, 495 litres consumed by green roof tops. reducing overall pressure on Risebergabäcken by 10 %

The flooding as well as the suggested architectural steps, effects landowners, puplic management, businesses, the prison, kindergartens and schools as well as individuals. Through the involment of the above mentioned, incorporating biological, social, economic, technical and cultural systems, new structures can emerge pinpointing possibilities waiting to be explored. New communication channels can apear.

Approaching Fosie as a mosaic structure while processing spatial interventions, new ways of understanding can be discovered. As such the development of waterways establishes new meeting points. Directly - by making space accessible, secondly by inviting the community to participate rather than have the roll of a passive audience. A demanding process - no doubt, as it involves many different sectors and individuals with different goals and focus points. It’s a challenge - daring the planners, architects and the users of Fosie to step out of their own enclosed hierarchies to be active participants in the search to prevent flooding. Through flexibility and evolving strategies, spatial interventions can provide participation and approaches nor yet identified. It is an approach to meet the demands of environmental changes with solutions and consciences beyond water management alone.
