Some rather grim images were sent out from our picture desk yesterday. Taken on Sunday by Ardiles Rante, they show the devastation caused by fire in the peatland forests outside Pekanbaru, the capital of Riau province in Sumatra. So that's another few thousand tonnes of carbon dioxide sent up into the atmosphere, and seeing photos like these make me realise our ongoing campaign to protect these forests from the ever-expanding palm oil industry is even more essential.

It's been a little while since I've updated here about the Esperanza's Forests for Climate tour of Indonesia, but continue it most certainly does. For our exploits crossing from one end of the country to the other and our stop in Jakarta, catch up on the Forests for Climate blog.

But we've arrived in Sungai Pakning, a small port on the coast of Riau in Sumatra, and the Esperanza is anchored in a wide, silty channel running between the mainland and two islands, Pulau Bengkalis and Pulau Padang. The soupy water flowing gently past the ship will be down to the Siak river, the mouth of which is just a few miles south.

The Governor of the province of Riau on the island of Sumatra in Indonesia has pledged to halt deforestation, which could help protect Riau's vast peatlands and forests that store 14.6 billion tonnes of carbon. Just to give you an estimate of what that figure means, it's the equivalent of an entire year's greenhouse gas emissions for the entire planet. Moreover, aside from being an important carbon store, this area is also important for biodiversity and critical for the people that depend upon these forests for their survival.
