Their experiences could go a long way towards ameliorating the impacts of the effects of climate change - but only if they can be validated scientifically and communicated effectively to other communities that also need to adapt.
The good news is that there is a growing effort to make sure this happens.
Last week, at the 5th International Conference on Community Based Adaptation to Climate Change, more than 300 international climate-change experts met in Bangladesh, left the meeting hall in Dhaka, and went out to see those resilient communities.
Delegates were split into eight groups, and they travelled to different parts of the country for three days to learn from people, government organisations and NGOs about how communities are protecting themselves from drought, flood, and rising temperature and sea levels. Read the full report here.
