Make Water Matter: A Review of Today's Water Issues.

This SlideShare discusses the major issues our global society is faced with relative to Water Security, Quality, and Hazards. We also discuss how water is linked to all aspects of life ranging from food to energy.

Our goal is to promote awareness, encourage individuals to take action, and to "Make Water Matter!"

  3. 3. The World Water Situation 97% Seawater (non-drinkable) 2.5% Frozen fresh water 0.5% Available fresh water 10,000,000 km3 stored in underground aquifers. 119,000 km3 net of rainfall on land after accounting for evaporation 91,000 km3 in natural lakes. Over 5,000 km3 in man made storage facilities and reservoirs since 1950. 2,120 km3 in rivers – constantly replaced by rainfall,melting snow, and melting ice Source: Facts and Trends, Water, World Business Council for Sustainable Development
  4. 4. By 2050, at least one in four people is likely to live in a country affected by chronic or reoccurring shortages of fresh water Image courtesy ofgraur razvan ionut / FreeDigitalPhotos.net Global freshwater demand is expected to exceed current supply by over 40% in 2030 2014 40% 2030 Source: http://www.weforum.org/content/global-agenda-council-water-security- 2012-2014 Image courtesy of arztsamu/ FreeDigitalPhotos.net
  5. 5. 2.6 billion people lack access to basic sanitation services, such as toilets or latrines Image courtesy of xedos4 / FreeDigitalPhotos.net Source: http://www.weforum.org/content/global-agenda-council-water-security-2012-2014
  6. 6. 1.7 billion people have gained access to safe drinking water but 884 million people are still without it Source: http://www.weforum.org/content/global-agenda-council-water-security-2012-2014
  7. 7. Each day, an average of 5,000 children die due to preventable water and sanitation-related diseases Image courtesy of Vlado / FreeDigitalPhotos.net Image courtesy of David Castillo Dominici / FreeDigitalPhotos.net Source: http://www.weforum.org/content/global-agenda-council-water-security-2012-2014
  8. 8. Source: http://www.unwater.org/activities/awareness-campaigns/world-toilet-day/en/ WORLD TOILET DAY 11.19 November 19 is formally recognized by the United Nations General Assembly as World Toilet Day The objective is to make sanitation a global development priority and urge changes in behavior and policy on issues ranging from water management to ending open-air defecation World Toilet Day intends to raise awareness of sanitation issues – including hygiene promotion, the provision of basic sanitation services, sewer and wastewater treatment and reuse in the context of integrated water management – and make a case for sanitation for all

  11. 11. In developing countries 70% of untreated industrial wastes are dumped into water Image courtesy of federico stevanin/ FreeDigitalPhotos.net
  12. 12. The contribution of the food sector to the production of organic water pollutants is 40% in high-income countries and 54% in low-income countries Image courtesy ofadamr/ FreeDigitalPhotos.net
  13. 13. The Result Approximately 3.5 million deaths related to inadequate water supply, sanitation, and hygiene occur each year, predominantly in developing countries. Poor water quality incurs many economic costs: degradation of ecosystem services; health-related costs; impacts on economic activities such as agriculture, industrial production, and tourism; increased water treatment costs; and reduced property values.

  14. 14. Image courtesy ofsmarnad/ FreeDigitalPhotos.net Water security is defined as the capacity of a population to safeguard sustainable access to adequate quantities of acceptable quality water for sustaining livelihoods, human well- being, and socio-economic development, for ensuring protection against water- borne pollution and water- related disasters, and for preserving ecosystems in a climate of peace and political stability.

  22. 22. Water and Food Agriculture accounts for 70% of all water withdrawals when comparing it to the municipal, industrial, and energy sectors According to the Food and Agriculture Organization food demand is predicted to increase by 60% in 2030 Image courtesy Gualberto107,/ FreeDigitalPhotos.net
  23. 23. Water and Food Economic growth and individual wealth are shifting diets from starch-based to meat and dairy, which require more water Source: World Water Development Report 2012
  24. 24. This dietary shift is the greatest impact on water consumption over the past 30 years, and is likely to continue well into the middle of the 21st century Source: World Water Development Report 2012

  30. 30. Water and Energy Roughly 75% of all industrial water withdrawals are used for energy production. Energy is required for two components of water provision: Pumping Treatment (before & after use) Image courtesy Master isolated images/ FreeDigitalPhotos.net Source: World Water Development Report 2014 - Water and Energy
  31. 31. Water and Energy By 2035 water withdrawals could increase by 20% and consumption by 85%, driven by a shift towards higher efficiency power plants with more advanced cooling systems (that reduce water withdrawals but increase consumption) World’s Total Water Withdrawals in 2010 According to the International Energy Agency, global water withdrawals for energy production in 2010 were 583 billion m3 (representing some 15% of the world’s total withdrawals), of which 66 billion m3 was consumed Image courtesy sritangphoto/ FreeDigitalPhotos.net
  32. 32. WATER, FOOD, AND ENERGY NEXUS Water is an input for producing agricultural goods in the fields and along the entire agro- food supply chain. Energy is required to produce and distribute water and food: Pump water from groundwater or surface water sources Power tractors and irrigation machinery Process and transport agricultural goods Image courtesy Vlado/ FreeDigitalPhotos.net Source: World Water Development Report 2014

  36. 36. WATER AND CLIMATE CHANGE . Water is the primary medium through which climate change influences the Earth's ecosystems and therefore people’s livelihoods and well- being More severe and more frequent droughts More severe and more frequent floods Source: UN-Water Key Messages on Climate Change and Water
  37. 37. WATER AND CLIMATE CHANGE Source: UN-Water Key Messages on Climate Change and Water Image courtesy digitalart/ FreeDigitalPhotos.net Higher average temperatures and changes in precipitation and temperature extremes are projected to affect the availability of water resources through changes in rainfall distribution soil moisture glacier and ice/snow melt river groundwater flows These factors are expected to lead to further deterioration of water quality
