Of course he blames the NGOs. They've been fairly vocal against his policies for opening up further territory for agribusiness, so now he's blaming them saying that they have set fires in order to discredit him. The end result is almost certainly going to be multiple attempts to ban as many of those organizations as possible on the grounds that they are some sort of eco-terrorists destroying Brazil's rainforest.
