Water efficient horticulture

Greenhouse horticulturists in East Africa need to use water sparingly. In dry periods, it is sometimes impossible to grow crops in greenhouses. Researchers from Wageningen UR have been running a pilot with Dutch entrepreneurs and a Kenyan horticulturist to come up with ways to conserve water.

The horticulturist collects and reuses the irrigation water not absorbed by the crops. This method makes it possible for him and others to harvest the same quantity of vegetables and flowers with at least a quarter less water. It also means less fertilizer is washed away, which in turn means less pollution of surface water. This is one of the ways Wageningen UR is working on improving quality of life.
