Cloud seeding has very effective results, but as any tool it has its limitations and must be operated correctly, otherwise it may be ineffective. Studies have shown that certain clouds or stages of cloud development are susceptible to sowing, while others are not.
Planting agents and methodologies used in current cloud seeding projects have been developed and refined for over 60 years. There is a general consensus in the community that technologies can increase seasonal precipitation in ranges of 10 to 15% when planting is effectively applied to suitable clouds.
It should always be considered that the result will be proportional to the amount of precipitation that falls naturally, so it is essential to operate this system continuously in time, taking advantage of the rainy years to accumulate ice in glaciers and to load underground water, and not only during dry years, where the same percentage of extra precipitation translates into scarce millimeters of falling water.
In general, the analysis have indicated that the estimated cost / benefit ratios in a number of operational cloud seeding projects have ranged from 1/5 to 1/15 or perhaps even higher in some cases. In our experience with the programs we have developed the benefit / cost ratio is an average of 1/10 to 1/12.
It should be noted that this is the cheapest method of producing fresh water. In rainy climates, it can produce 1,000 to 1,200 cubic meters of fresh water per dollar.
