One such strategy is cloud seeding which, contrary to popular opinion, is not new. It has been practiced operationally for over 50 years, with varying degrees of success...depending on how scientifically it is applied. China, despite the largest budget for weather modification, does not use proven scientific methods and does not publish results in the open literature. Therefore it is dubious whether their system, particularly rocket delivery, works. In the U.S., ground seeding is more successful and is even recognized by the American Meteorological Society as producing 10% more water seasonally, if designed and executed well. While 10% is no magic bullet, it can help fill reservoirs along with conservation, desalination, water banking etc. This situation requires a balanced approach of conservation and other strategies.
