Environmental Modification (ENMOD) Convention

Formal Title: CONVENTION ON THE PROHIBITION OF MILITARY OR ANY OTHER HOSTILE USE OF ENVIRONMENTAL MODIFICATION TECHNIQUES

Summary:

Under the Environmental Modification (ENMOD) Convention, each participating state "undertakes not to engage in military or any other hostile use of environmental modification techniques having widespread, long-lasting or severe effects as the means of destruction, damage or injury to any other State Party." With regard to peaceful uses of environmental modification techniques, the convention provides that the parties shall have the right to participate in the fullest possible exchange of scientific and technological information.

The ENMOD convention defines environmental modification techniques as changing -- through the deliberate manipulation of natural processes -- the dynamics, composition or structure of the earth, including its biota, lithosphere, hydrosphere, and atmosphere, or of outer space.

On 10 December 1976, the UN General Assembly adopted a resolution by a vote of 96 to 8, with 30 abstentions, which referred the Convention to all member nations for their consideration, signature, and ratification, and requested the UN Secretary-General to open the convention for signature.

ENMOD entered into force on 5 October 1978, when the 20th state to sign the Convention deposited its instrument of ratification.
