I live in the driest state on the driest inhabited continent. (South Australia.)
Drought is a natural process; every country has drought cycles.
Recently we exited a large and long drought cycle as the el nino cycle ended and the wetter La Nina started.
Our rain levels are highly dependent on these cycles, however when we get La Nina, other countries in the Pacific get El Nino and they enter droughts.
Some good practices though is, don't bother watering the lawn, it will die off during summer and become fully green during winter, go with plants in the garden which can survive long periods of droughts, fix your leaky taps.
Get water efficient showers, toilets and washing machines... Get large rain water tanks in every home that people can use for watering gardens, boiling the kettle, filling sinks and baths.
Not only does it help keep the water tables up, but you save money in the long run on your water bills.
Conversely, Governments should have backup plans when these natural occurrences happen, which will and do happen, we have desalination plants here, yes they use allot of energy, but it's a good insurance to have, because without water, people, crops, industry all will inevitably die/fail. - This is especially important when an area/country has had any kind of history of extreme droughts.
