International Alert convenes an expert roundtable, Building resilience – building peace, in Kathmandu on Monday 8 July. It’s the culmination of two and half years of research on the impact of climate change on local communities in Bangladesh, India, Nepal and Pakistan. I can’t be there so we recorded four minutes to camera as my contribution to the day’s events.

My brief comments emphasise the importance of thinking about the impact of climate change on four critical system – supply of water, food security, energy availability and supply natural resources supply. Responding to the challenge of climate change is about building resilience in those systems on which people everywhere depend.
