The biggest technology needed is actually excavators so we can dig ditches everywhere to soak up rain water and refill aquifers. Also building retaining walls, terraces and swales using permaculture style water management to reforest degraded grazing lands.

I think we need those excavators do dig our own graves, because this will probably not happen.
