Climate change - It's been three months since Cyclone Aila hit Bangladesh and eastern India. As we continue our emergency response, the BBC visit affected communites, reports Ben Beaumont.

A very quick blog to let people know that the BBC have spent the last week visiting communities affected by Cyclone Aila. They've actually visited the same community, Gabura, that I went to last November.

I remember thinking back then that this was a place right on the edge because of climate change. Hand-built mud embankments were all that stood between their homes and farmland and the rising sea. High tides and storm surges breached the embankments frequently, flooding their land with salt water, and ruining homes and rice paddies.

And then Cyclone Aila hit in May, and the storm surges that came with it wrought utter devastation. The people here are still recovering, still rebuilding, and inevitably talk has turned to how they can adapt in the future. Climate change means the rising sea will continue to destroy lives here, unless rich governments help to pay for vital adaptation measures.

Those adaptation measures include large-scale embankment projects, but also smaller-scale activities that Oxfam is already supporting - such as raising homes, introducing adapted farming methods, like floating gardens, or rearing ducks instead of chickens. Some of these are mentioned in the BBC report.

And, as the report says, over 20 million people in Bangladesh are vulnerable to future sea level rise. That's a number so big it's hard to comprehend the scale. But right now, those people are being engulfed by the sea. Those that can afford it will try to move to already overcrowded cities. Those that are left behind are starting to fight back. And it's up to us to help them.
