I recently met with a Member of the Bangladesh Parliament to discuss the potential for mitigation in the agricultural sector under IIED’s work on the economics of climate change in the agricultural sector. Agriculture produces 10–12 per cent of total global emissions but also has considerable mitigation potential — 70 per cent of which is in developing countries — and I expected the Honourable Member, a well known climate change champion, to back the cause. But he did not seem entirely convinced. Why should decision makers listen? What’s in it for them?
