Cloud Seeding and Sustainability:

Legal Implications of Weather Modification

Louna Farhat

 

Abstract: Cloud seeding is a weather modification technique used to tackle environmental problems like drought and water shortages. As cloud seeding becomes more common for increasing rainfall and enhancing ecological resilience, it raises critical issues under international environmental law, especially when unintended effects may possibly cause harm to neighbouring countries. The article examines the interplay between transboundary harm and legal principles like the responsibility to prevent environmental damage, the requirement for prior notification, and the pursuit of sustainable development. Considering scientific uncertainties surrounding the long-term ecological effects of cloud seeding, this article argues that governments should apply the precautionary principle to uphold the no-harm principle and safeguard future generations’ access to natural resources. By analysing relevant international legal frameworks, the article emphasises the need for clearer regulations to manage atmospheric interventions and encourage responsible environmental oversight.
