WATER - ENERGY - FOOD NEXUS IN MENA REGION KART...

Water-energy-food NEXUS is central to sustainable development in MENA Region. Demand for these
domains is increasing  driven with a rising global population  changing diets  rapid
urbanization and economic growth. Agriculture is considered to be the largest consumer of the
world's freshwater resources  and more than one-quarter of the energy consumed globally is
spent on food production and supply. The linkages between these essential domains require an
appropriately integrated approach to ensuring water and food security  sustainable agriculture
and energy production worldwide. Water is a finite resource having to serve exponentially more
people and usages  and so ensuring that everyone has access to a reliable supply and
sustainable progress. As water resources become more stretched  the energy and food sectors'
dependence on water means that decision-makers are now increasingly focusing on water resources
management  ecosystem protection  and water supply and sanitation as part of their policy and
practice for sustainable developments goals. In addition  there will need development of less
water-intensive renewable energy  such as hydropower and wind power  before it makes a
significant impact on water demand. As agriculture set to remain the biggest user of water into
the middle of this century  efficiency measures along the entire agrifood technologies can help
saving water and energy  such as precision irrigation based on information supplied by water
providers  which can motivate farmers to invest in their systems ensuring the best returns from
their water investments. The expert workshop held in Aswan  Egypt aimed to exchange knowledge
and to share information on water-energy-food challenges and solutions  and to establish a
sustainable network of water experts in the MENA Region.
