Drought emergency

After one of the driest periods in history, 2014 is on track to be the hottest since records began. How do we adapt to these extreme climate conditions which may be here to stay ?

The Down to Earth team heads to California, where 100% of the territory is in some form of drought, more than half of it deemed exceptional. In the state's prestigious Napa Valley vineyards, winemakers are turning to technology to economise the little water available. With reservoirs at all-time lows, conservationists are also in overdrive to bring already-endangered salmon back from the edge.
Further south in Mexico, similarly dry conditions are causing a divide among scientists, environmentalists and community groups. Corn is a crop particularly dear to Mexicans and the issue of whether to introduce a genetically-modified strain, better equipped for the drought, is splitting the country in two.
