Cloud seeding is the process of spreading either dry ice or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain.
South Africa had a rich history in rainfall enhancement research, but funding was stopped in 2000. Since then NO further research has been conducted.
Keep in mind with cloud seeding you treat the storms already developing like a thunderstorm so cloud seeding certainly isn’t going to bring you out of a drought.
Cloud seeding will NOT work in the Western Cape since we are mostly depended on frontal systems to bring our annual rainfall therefore the type of rain that we get in the Western Cape is unfortunately not conducive enough for rainfall enhancement.
