The tropical climatic conditions prevailing in South and Southeast Asia are extreme. Temperature and relative humidity in countries like Bangladesh, Sri Lanka, Burma, Thailand, Indonesia and Malaysia are very high throughout the year. Western parts of India, Afghanistan and Iran have a dry climate. In most parts of India, there is the monsoon type of climate, i.e. alternating dry and wet seasons. Such conditions accelerate the damage caused to cultural property. Light which is very intense in the tropical countries is another factor. Danger due to atmospheric pollution is increasing because of rapid industrialization. Most countries in this part cannot afford to have airconditioned buildings for their museums. Research programs are needed which can solve some of these special problems. -- AATA
