Water scarcity in the Middle East

What can be done? Improve water management by:

• Efficient water use • Groundwater conservation • Adequate water tariffs • Creating new water sources (reuse and desalination)

Desalination plays and will play a critical role in the future water supply for Middle Eastern countries

Keys to solar driven desalination

• MENA region has huge potential to produce solar energy

• Solar energy is more predictable than most of other RE sources1

• RO, CSP and PV are scalable technologies • Level of technological development (relevant advances

have been done to address this challenge) 1 PRODes 2010
