Water scarcity means there is not enough water to go around. There is a need to reduce demand or increase supply - or someone loses out.
Freshwater is the most important resource for humankind, cross-cutting all social, economic and environmental activities. It is a condition for all life on our planet, an enabling or limiting factor for any social and technological development, a possible source of welfare or misery, cooperation or conflict.
