What does Valentine’s have to do with Kenya?
A lot, although if you can’t imagine it very well. Every Year, Valentine’s Day causes a real boom of the flower industry. The German, for instance, spend about 3 billion euro on cut flowers per year, thereof 1 billion for roses.
Kenya, with its big rose- and pink farms around the Naivasha Lake, supplies a quarter of the imported cut flowers on the European market.
At first glance, this doesn’t seem to be a problem but in respect to the aspect water, the whole thing has a flipside: Flowers consist two-thirds of the most important and valuable element water. To result from this, the amount of water an average flower exporter delivers to Europe per year could satisfy the needs of water of a city with 20000 (!) inhabitants!
When draught dominates, the farms suck a determined quantity of water out of the lake. However, the sewage, polluted by phosphates and azotes, sets back and destroys the natural balance of the lake: Water hyacinths cover almost the whole water surface like carpets, whereupon the oxygen can’t reach the surface. In this way, the lake is killed slowly.
Many different, partially forbidden, chemical substances which are used for fertilization or protection of the plants will burden the environment for years. Absolutely necessary in the flower industry: ecological and social sustainability !
