Creating a legal framework requires treating airborne moisture as a shared resource rather than a national asset. Nations could adapt the UN Convention on the Law of the Non-Navigational Uses of International Watercourses to cover atmospheric moisture. This shift would move the focus toward equitable utilization.
Practical enforcement depends on transparency. A mandatory international registry for all drones dispersing Silver Iodide (AgI) or salt particles would prevent secret operations. To catch atmospheric theft, a neutral body, perhaps the World Meteorological Organization (WMO), would need satellite data to correlate seeding events with precipitation deficits downwind.
When one country’s rain-making triggers a drought next door, a predetermined compensation mechanism must kick in. Joint river basin authorities should expand their mandates to include the sky. Instead of lawsuits, neighboring states could co-manage seeding schedules based on regional humidity maps. This removes the incentive for unilateral action. It turns a potential conflict into a technical coordination problem.
