Problem Memorandum

RE:
Sustainable Water Use
DATE:
February 9, 2015
The world is running out of fresh water. This is a phrase you may have heard
repeated often when talking about the effects of climate change, or the problems of
water access in the third world, but the issues surrounding the global water crisis
have already begun to show themselves domestically and will continue to intensify
over the next 2-3 decades. It is imperative that we begin to address this issue now,
as scarcity of fresh water will profoundly impact the prosperity of our nation in
terms of health, food production, manufacturing and security.
There is more water on our planet than any other place in the known universe.
However despite almost two thirds of our planet being covered by water only 2.5
percent of that water is fresh. Of that 2.5 percent, about 1.6 percent is frozen in
glaciers and the polar ice caps. The majority of the remaining .8 percent is buried
deep in inaccessible underground aquifers (Solomon, 2010). That tiny amount of
accessible, fresh surface water has been responsible for sustaining the entirety of
humanity up to this point. But with the demand for water increasing per capita
every year, and the UN projecting the population to reach 10 billion by 2050, the
amount of available fresh water will not be enough to sustain the population
(National Geographic).
Many African and west Asian countries are already experiencing extreme water
stress. We are currently seeing extreme drought in the American southwest that will
take years to recover from. By 2050 four billion people are projected to face water
scarcity, about 40 percent of the projected global population (Gardner 1997).
Globally, 70 percent of fresh water is used for agriculture; about 22 percent is used
in manufacturing. Without targeted intervention now, the effects of this water
shortage will be devastating. We can expect droughts in the American Midwest and
Southwest. With the majority of our agriculture coming from our driest regions, the
increase in the scarcity of water will cause food prices to rise nationally. A similar
effect will be seen in the manufacturing sector, as water is crucial to many
processes. In more severely water stressed countries in North and Sub-Saharan
Africa, and Western Asia, the first wars over water rights will be fought, massively
destabilizing these regions. This will cause a massive human rights crisis, paving the
way for violence and extremism, and putting our own national security at risk.
The world’s water problem has two elements: access and scarcity.
The infrastructure does not currently exist to provide access to water for a large
percentage of the population. By 2025 it is estimated that 230 million Africans will
not have access to fresh water (Falkenmark, 1989). It is imperative to global
stability that within the next 25 years the infrastructure is built up to the point that
water can be supplied to the areas that will be hit the hardest, giving relief and
easing tensions.
The second and larger problem is scarcity. Today in 2015 we have allotted about 8
percent of accessible fresh water for domestic use. The vast majority of what is left
about 70 percent of available fresh water is used for agriculture. We can meet the
coming demand for fresh water by diverting some of the supply away from
agriculture and toward domestic purposes. A 10 percent reduction in water use for
agriculture (globally) would effectively double the supply available for households.
This would be an important first step in a future of safe, sustainable water use.
Thank you, Senator for taking the time to read this memo, I look forward to our
future correspondence and any help I can provide you in this matter.
Best Regards,
Ben Dimond
