Title: Facing the Freshwater Crisis
Author: Peter Rogers

B:
Scientists expect water scarcity to become more common in large part because the world’s population is rising and many people are getting richer (thus expanding demand) and because global climate change is exacerbating aridity and reducing supply in many regions.What is more, many water sources are threatened by faulty waste disposal, releases of industrial pollutants, fertilizer runoff and coastal influxes of saltwater into aquifers as groundwater is depleted. Because lack of access to water can lead to starvation, disease, political instability and even armed conflict, failure to take action can have broad and grave consequences.More extensive use of drip-irrigation systems, which minimize consumption by allowing water to seep in slowly either from the soil surface or directly into the root zone, would also do much to stem demand for irrigation water

After read this article, I learned that water conservation should not be considered an option any longer. Current circumstances require our full attention if we hope to thrive as a civilization. If these statements sound dramatic, it is because much of the world is currently suffering due to a lack of clean water.Statistics around the reveal that our fresh water supply is practically nonexistent.Some simple but effective water conservation ideas you can put into action at home are Taking Quick Showers, Looking Out for Leaks, Turning Off the Tap, Improving Your Toilet, Keeping Trash from the Toilet, and Using a Bucket.
So What?
lack of access to water can lead to starvation, disease, political instability and even armed conflict, failure to take action can have broad and grave consequences
Who Said?
Peter Rogers
What If?
Wise use of such power will become increasingly important as the years go by because the world’s demand for freshwater is currently overtaking its ready supply in many places, and this situation shows no sign of abating.
This Remind Me Of?
The struggle for freshwater has contributed to civil and military disputes in the area. Only continuing negotiations and compromise have kept this tense situation under control.

- Politicians there have allowed irrigation water to be shifted away from farming operations
- to cities and suburbs, while permitting recycled waste- water to be employed for landscaping and other non-potable applications
- Wise use of such power will become increasingly important as the years go by
- because the world’s demand for freshwater is currently overtaking its ready supply in many places
- this situation shows no sign of abating
- when people increasingly demand more water than is available or
- safe for use—or out- right shortages
- lack of access to water can lead to starvation, disease, political instability
- even armed conflict, failure to take action can have broad and grave consequences.

- the man-made lakes Mead and Powell, both of which are fed by the over stressed Colorado River
- Decades ago the agriculturalists and the government there divided up the waters among the human users— grape growers
- wheat farmers and sheep ranchers—in a sophisticated way based on equity and economics
- the quantities of water that the planners had set aside to sustain the local environment were inadequate
- an underestimation that became apparent during periodic droughts—in particular
- the one that has wrought havoc in the area for the last half a dozen years
- The struggle for freshwater has contributed to civil and military disputes in the area. Only continuing negotiations and compromise have kept this tense situation under control
- The affluent also insist on services such as waste water treatment and intensive farm irrigation
- encourage water agencies to build recycling and reclamation systems
- When the goal is to save water, another key strategy should be to focus on the largest consumers
- modest 10% rise in irrigation efficiency would free up more water than is evaporated off by all other users
- achieved by stopping up leaks in the water-delivery infrastructure
- by implementing low-loss storage of water as well as more efficient application of water to farm crops
- Underground storage would limit evaporation loss
- More extensive use of drip-irrigation systems, which minimize consumption by allowing water to seep in slowly either from the soil surface or directly into the root zone,
- would also do much to stem demand for irrigation water
- improvements in irrigation efficiency as well as crop yields
- can help hold any increases to reasonable levels
- The notion of virtual water may sound initially like a mere accounting device
- but provision of goods—and the virtual-water content of those goods
- is helping many dry countries avoid using their own water supplies for growing crops, thus freeing up large quantities for other applications
- civil engineers can employ this technology to decouple water supplies from sanitation systems
- a move that could save significant amounts of freshwater if it were more widely employed
