Which of these is the best method to solve the water crisis in a location because of long periods of drought?

remove plants to increase rainfall
reuse water left over from cooking
turn on the dishwater as soon as it is half full
wash clothes in machines instead of hand washing them

reuse water left over from cooking

Explanation:

As a draught is a natural disaster and it stays for longer period of time and thus one has to try to conserve as much as the water resources as one can, as the removal of the plants will not do any help and the, one should try to conserve and reuse water as much as possible so as to stop the wastage. The water is a valuable resource on earth and a lot of water can be saved in the process of cooking and thus reducing the need to use more water and thus preventing it from getting washed away. As we cannot use washing machine water and nor the dishwasher can go any good so try to minimize the use of water as much as possible.
