Water is a 鈥渟trategic instrument in the creation of a safer, healthier, more nutritious, less aggressive world,鈥� said听听President and CEO Rodney Ferguson at the first event in a four-part series on water security organized by 澳门六合彩 and the听. Panelists at the event identified innovative and integrated efforts necessary to increase global water security in the face of growing water scarcity.Too Little Water

What drives demand? 鈥淔ood security, energy security, economic growth, and even land use change: These are the non-climate drivers that water resource professionals cannot afford to ignore. And if you add听, then we really are hard-pressed to think of a water-secure future that is not going to be increasingly difficult for us to achieve,鈥� said Volk.Water scarcity is not new, but the increasing听听that are affected is new: As many as two-thirds of world鈥檚 population experience extreme water scarcity for at least one month every year, said Richard Volk of USAID. If we continue our current consumption patterns, 鈥渢he demand for fresh water could be as much as 40 percent greater than听听in just 12 years from now,鈥� he said.听听

罢丑别听听are borne most heavily by 鈥渕ost vulnerable, the poor, marginalized,听听and ecosystems, particularly the ecosystems where these vulnerable depend,鈥� said Annette Huber-Lee of Stockholm Environment Institute.听听Water scarcity raises questions about competition: Who has the power, and how is water allocated?

Thirsty Food

Our agricultural systems account for听听we use. 鈥淭he cup of coffee I had this morning took 140 liters to produce, a kilo of rice takes 3,500 liters of water to produce, and a kilo of beef takes 15,000 liters of water to produce,鈥� said听听of Tetra Tech.

To meet demand, 鈥渨e need听听by 2050,鈥� said Choularton. 鈥淵ou can鈥檛 have food security without water security.鈥� Water scarcity has long-term and wide-ranging听, leading to poor nutrition and poor health. Twenty percent of global听, or stunting, is related to environmental factors, particularly drought. 鈥淚n Niger, if you鈥檙e born during a drought year, you鈥檙e 50 percent more likely to be stunted than if you鈥檙e born in a non-drought year.鈥�

鈥淲e want to see these problems solved,鈥� said Rabinovitch. Mars鈥� commitment--听for sustainability鈥攊s nothing to snicker at. Mars partners with the World Resources Institute and Pacific Institute to address sustainability through a science-based approach, including measuring its water use throughout the supply chain.Drought-driven food insecurity can have global consequences. For example, the 2010 drought in Russia spurred wildfires that decimated wheat crops and led the Russian government to stop exporting wheat, said Kevin Rabinovitch of Mars Inc. The resulting spikes in food prices are considered one of the听听leading to the unrest during the Arab Spring. More recently, droughts in Syria, made worse by poor agriculture policies, drove farmers to migrate to the cities, where repression by the Assad regime inflamed grievances, starting a devastating civil war that continues today.

How do we produce more food amid growing water scarcity? 鈥淭he best examples of sustainable improvements in food security are the places where there鈥檚 been听听in good watershed management, soil and water conservation, and changing that dynamic of land pressure, degradation, increased disaster risk, and low production,鈥� said Choulartan.

Upstream Problems: Dumb Dams and Pollution Time Bombs

To meet the energy needs of our growing population, we are experiencing a global boom in dam construction, with 4,000 new high dams planned or under construction, said Volk. Dams can deprive ecosystems of natural flow and downstream users of essential fresh water, but they are also a relatively low-carbon source of energy. However, 鈥渟mart鈥� dams can be built using knowledge of river flows and sedimentation, and designed with flexibility that incorporates uncertainty, said Dalton. But these dams are only smart until someone downstream builds one that isn鈥檛.Water pollution is a 鈥渢ime bomb,鈥� said James Dalton of the International Union for Conservation of Nature听听IUCN鈥檚 assessment of the world鈥檚 265听听found that river basin managers did not know enough about pollution, especially its impacts on food supplies and fish stocks. But we do know that pollution affects biodiversity. 鈥淭he greatest听听around the world is in freshwater systems,鈥� he said. 鈥淏ecause it is on our watch, we鈥檒l be responsible for that.鈥澨齨eeds to ensure that economic and social benefits of transboundary water resources are balanced with environmental and biodiversity benefits. 听

Sustaining Water, Sustaining Stakeholders

Media and governments 鈥減ay attention to floods and droughts because it hurts. And it hurts socially, it hurts economically, it hurts because you have to pay to rebuild, as well as fix the damage. And it also hurts because you have to re-plan about how you do it in the future,鈥� said Dalton.

To get ahead of the hurt, engaging stakeholders is essential. The Stockholm Environment Institute holds workshops to engage competing stakeholders in a river basin. Before the workshops begin, the stakeholders rarely share a unified vision, but by the time they end, the participants have a better understanding of each other鈥檚 interests and the impact of their decisions on their neighbors, and thus are able to negotiate mutually beneficial steps.

We all have to share limited water supplies, so we must show how shared benefits can become regional and global benefits, said Dalton. Addressing water issues 鈥渞equires a shared understanding of how we are all interconnected and interdependent,鈥� said Huber-Lee.
