- Use GMO to produce plants suitable for higher temperatures and droughts. 
- Massive water desalination using photovoltaics.
- Recultivation of arid lands and deserts such as Sahara use new plants and desalinated water. 
- Better collecting of the rain water using networks of dams (for example in monsune time).
- Much more effective, regulated irrigation direct to plant's root. 
- Use photovoltaics for daily energy production used for cooling human dwellings.
