WHAT ARE POROUS CITY INTERVENTIONS
Urban areas face critical climate resilience issues. Decades of rapid urbanization worldwide have created vulnerabilities and increased water stresses in urban landscapes. Urban sprawls destroys cities’ natural ecoservices and capacities to adapt.
In Bangkok, agricultural land once absorbed seasonal flood and cycles of monsoon rain. Today, decades of rapid urban development have paved over this permeable surface. Bangkok faces heavy season rain, and today the water has nowhere to go, which causes massive flooding and environmental problems. This is only getting worse with effects of climate change.
Porous City Network improves urban resilience through porosity.
What is porosity? It’s a like sponge - it’s a space that can absorb water, like the agricultural land that was here before extensive urban development. We want to re-introduce permeable surface back into the city, through a network of public green spaces projects, like small parks, urban farms, and canals. Urban porosity is critical to managing water stress in Bangkok.
POROUS CITY INTERVENTIONS
Retention Pond can treat the storm water and non-point source of water from the urbanization by the designed to support emergent and submerged aquatic vegetation.
Retention lawn can help to control pollution and erosion control, the design can be locate in front of the residential zone, which can create cooling effect and heat dissipation.
Detention pond act as the storage basins or facilities that provide flow control through attenuation of storm water runoff. Detention pond help
to control the runoff of waste water from the street and traffic.
Green link can help the problems of storm water-control infrastructure, green alleys also will increase the reliability of local water supplies by
reducing runoff, improving water quality, and supplementing the City’s water supply via groundwater recharge.
A restored canal would preserve structures and artefacts the context of the city, built to serve a transport system and help to prevent fooding
situation in the city because the canal is the pass way to drain the high amount of water in the raining season.
Park help to create positive effect on mental and physical health of people. Parks resources can mitigate climate, air, and water pollution impacts on public health.
The Pocket Park can create the various type of public activity and increase the social interaction in the area and can increase the walkable to the people and decrease the private car user.
Urban farming can increase food security because the urban poor can earn or supplement their income. Urban farming is a great way to efficiently use the land we do have to feed the people.
The Rain Gardens perform to manage the surface runoff to prevent the stagnant water that might create the contaminated waste water.
Green roof : Three stories building with the green roof can roofs can lead to 5-15% electricity reduction during summer and conventional roof surfaces can exceed ambient air temperatures by >50°C. Green roofs could reduce temperatures a further 2°C & extend a 1°C cooled area over a larger geographic region.
