Water and Green Roofs in Dry Climates - A Speculation
- Resumen
- In temperate climates green roofs have proven to be beneficial for urban water management. Green roofs retain stormwater, ease flooding and reduce combined sewage overflows. Green roofs can have a positive effect on stormwater quality and alleviate groundwater recharge. In the last decade an increasing amount of green roofs have been installed in dry and Mediterranean climates. This paper surveys the potential benefits of green roofs as part of urban water management strategy in these climates. It comes to the conclusion that green roofs can have hydrological benefits if certain conditions are given. Their usefulness might increase due to predicted changes induced by global warming. In regions of water scarcity, green roofs can only be installed if their irrigation is part of a sustainable water regime. Besides hydrological advantages other benefits of green roofs, like cooling effects, might be of equal or higher importance in hot and dry cities.
