Preventive measure and remedial measure adopted. Remidial: Using chemicals to artificially cause the release of rain from clouds is called cloud seeding. Besides the rockets, Chinese authorities have also sent large drones into the skies above Sichuan province, another central region of the country. The aircraft have been shooting silver iodide flares into the atmosphere, also in the hope of prompting precipitation.Also,provispde financial aid. Preventive: South-to-North Water Diversion Project, a colossal engineering effort to build canals and tunnels that will ferry water from the south of China to the north. The estimated total cost is $62 billion, and an $8.9 billion tunnel to Beijing was announced in August2022. Beside, research the GM crops
Suggestions: First, I am not really agree with the policy with it ,because the stopping electricity supply make citizen live with difficulties .Although it can solve the problem, but I think Chinese government can only close the electricity supply for public service ,also they can use coal generation electricity or plan other area where not suffered in drought (not water supply)
Beside, we can plan more wind or sun light infrastructure that will make the supply become more stable due to many method.
