Water is life - and when it's gone, the thirst comes.
Times with less water, or droughts, have always been a natural part of weather around the planet. But climate change has been linked with more frequent, more severe and longer dry spells. Especially in more arid regions of the developing world, drought often causes crop losses or lower yields, which threatens food security there. Drought is also increasingly becoming a problem for hydropower, or generation of electricity with water. In addition, drought is linked with stronger and more intense wildfire, and even with political instability.
Prolonged droughts and crop failures are causing some Indian villages to empty. For the women and elderly left behind, it's a struggle. As temperatures continue to rise, there's little hope their loved ones will return.
In the aftermath of natural disasters, decades of political crisis and facing an increasingly unpredictable climate, farmers in Haiti are turning to ecological farming methods to hold onto their livelihoods. Some see it as the only way to feed their families and continue farming in the face of climate change.
How can we be better prepared for disasters like floods fueled by climate change? We hear from one of China's sponge cities how it's done. The Rio Grande in New Mexico was once an impressive river, but it's no longer what it used to be. How are locals coping? And how bikes can change lives.
