The ASEAN Agreement on Transboundary Haze Pollution (AATHP) is a legally binding agreement signed in 2002 by all ten member countries of the Association of Southeast Asian Nations (ASEAN). The agreement aims to address the issue of transboundary haze pollution, which occurs when smoke and pollution from fires in one country drifts across borders and creates health and environmental problems in neighboring countries.

The main objective of the AATHP is to prevent and monitor transboundary haze pollution by promoting cooperation between ASEAN member countries. The agreement outlines several key principles, including the need for countries to take preventive measures to avoid the occurrence of fires and haze, to respond promptly and effectively to any incidents of transboundary haze pollution, and to enhance cooperation and coordination among ASEAN countries and other stakeholders.

One of the most significant aspects of the AATHP is the establishment of a regional monitoring system, which includes the development of a standardized haze monitoring system and the establishment of a network of monitoring stations across ASEAN countries. Through this system, member countries are required to share information on haze levels and provide early warnings to neighboring countries in the event of a haze outbreak.

In addition to the establishment of a monitoring system, the AATHP also includes measures to promote sustainable land use practices and fire prevention. Member countries are required to take measures to prevent and control fires, including banning illegal land clearing practices and promoting sustainable forest management. The agreement also calls for the development of policies and programs to promote sustainable agriculture and land use practices.

Overall, the AATHP is an important agreement that seeks to address a significant environmental and health issue in Southeast Asia. With the cooperation and commitment of all ASEAN member countries, the agreement has the potential to significantly reduce the occurrence of transboundary haze pollution and promote sustainable land use practices across the region.
