In 1992, the Earth Summit brought together many East Asian nations to discuss environmental issues and problems.  Since then, many regional projects have started up and have been successfully implemented.

The Asian Network on Problem Soils was created in 1989 by 13 countries in the region.  The program is now working with the UN to study the causes of land degradation and is investigating the effects of fertilizers.

The South Asia Cooperative Environment Program is working towards raising public awareness about environmental issues, exchanging information and technology, providing training to environmental regulators, and managing various natural ecosystems.

The South Pacific Regional Environmental Program aimed to unite the island nations of the Pacific to strengthen the environmental regulation abilities of members states.

To promote biological diversity, Asian countries met at the Convention on Conservation of Nature in the South Pacific, the ASEAN Agreement on the Conservation of Nature and Natural Resources, and the Convention on the Protection of the Natural Resources and the Environment of the South Pacific.  Planning to preserve biological diversity, the countries decided to increase research and development and conserve the habitats of endangered species.

The Asian Development Bank has helped the region to promote environmental training and the exchange of information related to environmental problems.

International scientific studies are now taking place, researching such problems as acid rain.  Other studies are looking at the greenhouse effect, climate issues, and marine environments.
