As the climate changes, and 'local'/'regional' environments change such that, species which formerly could not survive there, now can; invasive plants, pests, and disease can compete for sun, soil moisture, nutrients. They come in because the conditions which formerly barred their entry no longer exist. They weren't 'relocated.'

Cane-cutters in Guatemala are dying from heat-index values which have never been seen since weather recordkeeping began.

Even with extant population demands, the aquifers held there own until the mega-drought kicked in. Recent massive rains and snow may not be any guarantee of aquifer recharge, if mountain freeze-lines continue to climb higher, with heat nipping at their heels, and early melt denies rivers water.
It's happening right now in Africa, Pakistan, the Rockies, the Andes, and China.
