Where I live, we have been without appreciable rain for nearly two months.
My garden wilted. My flowers wilted. The leaves on the trees started dropping early. But I have no real problem. I may be concerned for my garden, but I can take a hose and water it. I could do the same for my flowers, but I know they will survive and will return when the rain comes back. And I am sure the rain will come back.
Where I live, when compared to other places, we are water rich. We have clean water that flows from our taps whenever we want it. Where I lived before was along a wide meandering river that flowed down from up-state. My water came from a well. In my current location, I have water from the city. Both of these areas may be considered water rich. But where I had a well, I had to work at it a bit and have the well drilled deeper. Why? Because the water level of the native aquifer was slowly but continually falling.
Why was it falling? Was there less rain? No. There was plenty of rain throughout the state and the region. In many instances, it seemed there was too much rain. So why was the level of the ground water aquifer falling? Because there were more people. There were more people upstream and all along the river’s banks. There were more people taking surface water and ground water for their personal use and for industrial use, and in my state for agricultural use. So the aquifer level was falling – and it continues to fall.
About every five years I would notice my pump was struggling to lift water up the well. I would need to call a well-driller and have my personal well drilled deeper and deeper. This was not a solution. If anything, I was exacerbating the problem.
In that state, along the Atlantic coast, the total population of 24 coastal counties grew between 2000 and 2007. Several of the counties lost population or had a low growth rate, but half of the coastal counties had a growth rate greater than 15%. All these new people and their jobs were using more and more water. The counties up river were experiencing even more growth. The metropolitan areas drew in more and more people. And they took their share of the surface water and the ground water.
But compared to many places in our country and around the World, these 24 coastal counties were water rich. Some of the population increase was due to people moving into the state from other states. Part of it was the growth of the existing population. Both of these trends continue. It can be seen even on the state level that the more people there are, the more water is needed.
When you look at the World, our nation as I have mentioned is water rich. The September 14, 2019 issue of Science News, including an article , “One in four people live in a place of high risk of running out of water”. The article highlighted a growing, World-wide water crisis. It discussed a series of tools used by the World Resources Institute to calculate what is considered a high level of “water stress”. The article states that the World’s use of water increased 150% from 1961 to 2014. In that same time frame the World Bank indicates that the World’s population has more than doubled, from 3.1 billion to 7.2 billion. At a glance it might appear that the World’s population has learned to reduce their water requirement. But in actuality it indicates, that overall, the World’s people have less access to water.
In a water rich country like the United States, this is not evident, unless you have a well that you have to push deeper every few years. But for many people in the World safe and adequate water supplies is an issue.
As the World population grows toward 8 Billion, this issue will get worse. New methods of water use that conserve water will be needed, and new sources of water, such as the salt filled oceans, will have to be tapped. This will require improved – or new – technologies to prepare the water for consumption, including desalination of ocean water, and new distribution processes to get the water to the people, the animals, and the crops that need it.
