Green Roofs For Communities Below Sea Level
Could Rotterdam's water management program be a viable solution for New Orleans?
Green roofs have proven to be a godsend in offering urbanites localized food production and improved air quality while reducing city temperature. Yet, the Netherlands had a different priority in promoting green roofs, mainly with water retention:
Rotterdam's priority was for water retention, since the city has a shortage of areas where water can be stored following heavy rainfall. Water management has always been a major concern in the Netherlands, since approximately 60% of the country lies below sea level. The analysis of the potential of green roofs in Rotterdam that preceded the introduction of the subsidies focused heavily on their capacity for water storage in order to reduce peak water discharge following a rain storm and help prevent flooding.
