STARTING THE
CONVERSATION …
GLOBAL TRENDS
Welcoming 2.5 million new people by 2050…
with rising incomes increasing
consumption…
36% increase in energy demand by 2030
70% food demand increase by 2050
60% water demand increase by 2050
and a greater demand for water in food and
energy sectors… Water needs for power production to rise 85% by 2035
Irrigation doubling by 2050 to meet food demands
when we might face a 40% global shortfall in
water supply by 2030
… in a context of climate change
