Despite strong growth of organic farming in Ile-de-France in recent years, it still lags behind some areas of Germany, and current output is not keeping pace with rising demand. With respect to water, the greatest potential for green growth lies in alternative water management (rainwater management, green roofs, rainwater harvesting, filtering gardens) and the development of clean technologies (nanotechnology, seawater desalination). In Ile-de-France, it is above all in the area of R&D that job creation may be achievable, thanks especially to the presence of many research laboratories attached to large companies.
