Hi Alai,
Areas around lake Naivasha people are really suffering , especially farmers around Karate, Kinungi and some parts of Kinangop.
It doesn't rain these days because whenever rain clouds form, the flower farms around Lake Naivasha send a small aircraft to disperse the clouds using some kind of chemicals.
When it rains, the farms claim that many pests attack their flowers resulting in them using expensive chemicals to control the pests. I wonder why they see it ok to destroy the lives of others because of their flowers.
These people don't value the lives of communities they live around and so they destroy our lives because they don't want their flowers to be attacked. Why don't they go to areas where it doesn't rain much?
We are experiencing artificial drought around Naivasha and the owners of these farms never care. NEMA and Ministry of environment doesn't care. Nakuru County government doesn't even want to listen.

They also use it in kericho to prevent/disperse hailstorms that could affect tea bushes.

China's cunning multimillion-pound plan to manipulate the Olympic weather seems to be yielding results. While rain drenched the capital yesterday, the downpour that should have fallen on Friday night was averted; Olympic organisers fired a barrage of 1,110 rockets into the evening sky to make sure the 2008 Olympic opening ceremony was precipitation-free.

It has become a tradition in Beijing to seed the clouds before public holidays, such as National Day on 1 October, to make rain, disperse pollution and ensure clear skies on the day. But for the opening ceremony, the purpose was simply rain dispersal – bringing on a downpour but not on the Olympic stadium.

Friday saw the biggest effort yet, as the"weather changers" began firing rockets from a battery of artillery into the clouds above Beijing four hours before the opening ceremony and continued firing until 11.40pm, shortly before the finale.
