The haze is back and this time, it’s raising bigger questions about whether Southeast Asia has actually learnt anything from the haze crises of the past.

With Singapore’s PSI crossing into the unhealthy range in parts of the island, attention is once again turning to the forest and land fires in Indonesia and the smoke drifting across borders.
