The Southeast Asian haze is a major environmental problem facing the region and a much studied subject. Thus it may seem that there cannot be much new to say or write about it. Undoubtedly, significant progress has been made in both understanding and instituting policies and mechanisms to tackle it. But the problem continues to persist evenafter nearly two decades since the region experienced one of the worst episodes in 1997–98. It seems to appear and disappear much like the proverbial Cheshire cat in Alice’s Adventures in Wonderland.
