Commercial agriculture is a major contributor to the country's economy.
The country, therefore, is heavily dependent on agriculture, and, as a result of recent droughts, precipitation augmentation has become a vital component of this economic sector. Rainfall augmentation operations are carried out during all seasons which do not have sufficient natural rainfall. This technique involves the beneficial modification of summer convective rainfall to increase rainfall production efficiency. The approach encourages efficient rainfall formation through a collision - coalescence process which is enhanced or accelerated by the addition of hygroscopic nuclei into a storm updraft at cloud base. Augmentation provides additional water to crops when weather conditions are favourable and is required during periods when little or no rainfall would otherwise occur.
