Groundwater supplies around the world are under threat as drilling companies bore deeper and deeper wells.
The Ogalalla Aquifer is a vast underground lake that irrigates farms across the US Great Plains. It took thousands of years to fill, but human use could drain it in roughly a century.
Farmers are calling for South Australia to ramp up its desalination plant to free up more water from the Murray Darling.
The heatwave is unlikely to cause the price hikes of 1976 for a number of reasons.
In periods of water stress, farmers need support, research assistance and empathy from governments and competing water users.

The system that allocates water use in Australia's largest river basin relies on a shared commitment by states to uphold the rules. New allegations of water theft threaten to break that trust.
Official statistics in Tanzania do not capture small-scale irrigation, meaning that it's impact is unclear. Yet new research reveals that it's two to three times greater than previously thought
The current climate talks in Morocco are a golden opportunity for making strides on the adaptation of African agriculture. African countries need the tools necessary to do so.
Droughts are much bigger and slower than other natural disasters that hit Australia - meaning that despite their huge impacts, we still haven't figured out how best to protect ourselves.
Ever since British settlement, water rights in Australia's north have favoured landowners over traditional owners, effectively locking Aboriginal people out of agricultural development.
Toxic algal blooms were unheard of in Australia's major waterways before 1991. Now the Murray River has been struck by four major events in less than a decade, with more likely in the future.
For the Barkindji people, the Darling River has been a symbol of Aboriginal survival since colonial times. Now, the once busy NSW town of Wilcannia is in danger of losing its water.
It's full steam ahead for bringing vast increases in farming to northern Australia. In fact, probably too fast to adequately consider the environmental impacts.
South Africa has been hit by a severe drought and will not be able to produce enough maize - its staple food - in 2016. This will prompt a rise in imports and therefore food prices.
A government for the 21st century needs to work out how we can grow our food, manufacture goods and dispose of waste without making such a huge mess.
