INTERNATIONAL environmental treaties like the World Heritage Convention and the Convention on Biological Diversity show that the concept of national sovereignty must be tempered by the recognition of an interest of the international community in the conservation of resources found in different jurisdictions. The fact that states voluntarily accept limitations on their sovereignty by agreeing to international obligations to conserve some of their natural resources provide a basis upon which bilateral agreements on border area management may be developed.
