A new freely downloadable book

I would like to announce the publication of a book, which discusses the relationships between water and life. The book may be freely downloaded and circulated from the following link:


The United Nations’ World Water Day

On its home-page for World Water Day the United Nations points out the following facts:

“Today, 1 in 3 people live without safe drinking water.

“By 2050, up to 5.7 billion people could be living in areas where water is scarce for at least one month a year.

“Climate-resilient water supply and sanitation could save the lives of more than 360,000 infants every year.

“If we limit global warming to 1.5 degrees C above pre-industrial levels, we could cut climate-induced water stress by up to 50%.

“Extreme weather has caused more than 90% of major disasters over the last decade.

“By 2040, global energy demand is projected to increase by over 25% and water demand is expected to increase by more than 50%.”

A critical resource

Clearly, water is a crucial resource, and the future well-being of human society depends on how well we manage our global supply of fresh water.

This book discusses various aspects of the relationship of water with human society, and with all life on planet earth. Because of climate change, some regions are increasingly threatened by drought, while others experience catastrophic floods.

Water tables throughout the world are falling, as aquifers are overdrawn. Falling water tables in China were the reason why that country adopted its one-child policy. Because of water shortages, China may soon be unable to feed its own population, but, as Lester R. Brown has pointed out, this will not cause a famine in China, but as China increasingly buys grain on the world market, the price will increase beyond the purchasing power of some of the poorer countries, and it is here that the Chinese water shortages will cause famine.

Countries in the Middle East and Africa have been pæagued by drought in recent years.  Millions of people are now threatened with starvation because of failing agriculture and

deaths from lack of water among cattle herds. In Zimbabwe, grain production is down by 53%. Water levels on the Zambezi River are lower than they have been for decades, and Victoria Falls has become a trickle. Fish stocks on the river are in danger of collapsing.

Drought is also hitting the western hemisphere. Today, California and the southwestern states are plagued by drought. The Colorado River is reduced to a trickle when it reaches the Pacific, Water tables are falling. The Ogallala aquifer is overdrawn and disappears as it flows southward. Wildfires caused by extremely dry conditions have hit California and the Pacific Northwest.

Guatemala, El Salvador, Honduras, and Nicaragua are part of an area that has come to be known as the Dry Corridor. It is particularly vulnerable to the effects of climate change and drought because a large percentage of the people  in this region live in poverty and are dependent on agriculture, which, in turn, depends on adequate rainfall.

2019 was the fifth consecutive year of drought in the Dry Corridor. Because of failed crops and food insecurity, many people in the region plan to migrate, despite the hardships and risks that this entails.

During the years 2014-2017, Brazil experienced a severe drought, which affected the southeast part of the country, including the cities of Sao Paulo and Rio de Janeiro. Over half the area of Brazil was affected by the drought, which was considered to be the worst in 100 years.

I fear that by the middle of the present century, growing populations, water shortages, the effect of climate change on agriculture and the end of the fossil fuel era will combine to produce a famine involving billions of people, rather than millions. Today the high-yield Green Revolution crop varieties have warded off famine, but these varieties are dependent on intensive irrigation and heavy use of fertilizers (often produced today with the aid of fossil fuels). Thus, high-yield agriculture may be difficult to maintain in the future.

In many countries, large corporations have taken control of water supplies, and are now selling water at prices that poor citizens cannot afford. Maude Barlow, born in 1947 in Canada, is leading the struggle against the commodification of water. As the result of her campaign, the United Nations has declared water to be a human right. This is particularly important at a time when fresh water is becoming increasingly scarce.

Water plays a role in present conflicts, for example in the conflict between the government of Israel and the country’s Palestinian population. In the future, there may be many other conflicts over water, for example between China and India. China is building a canal to take water from the Tibetan Plateau to Beijing, thus reducing the amount of water in rivers flowing down from the plateau into India. Other dangerous water conflicts loom in regions such as Sudan.

The book also discusses the health of our oceans. Between 1751 and 1995 the amount of H+ ion in ocean surface water is estimated to have increased by 35%. Living organisms are very sensitive to acidity, and today we can observe the alarming death of many forms of marine life, for example the death of coral in the Great Barrier Reef and other coral reef systems. Over a billion people depend on fish from coral reef habitats for protein in their diets.

Our oceans are now massively polluted with carelessly discarded plastic waste. Plastic waste is found in huge quantities on the beaches of the remotest islands and in the blocked digestive systems of dead whales. A recent study found that in 2010, 8 million tonnes of plastic went into our oceans,

The last two chapters of this book are devoted to the role of water in biological specificity, upon which life depends, and the role of water in the origin of life, both on earth, and elsewhere in the universe.

I hope that you will circulate the links in this article to friends and contacts who might be interested.

John Scales Avery is a theoretical chemist at the University of Copenhagen. He is noted for his books and research publications in quantum chemistry, thermodynamics, evolution, and history of science. His 2003 book Information Theory and Evolution set forth the view that the phenomenon of life, including its origin, evolution, as well as human cultural evolution, has its background situated in the fields of thermodynamics, statistical mechanics, and information theory. Since 1990 he has been the Chairman of the Danish National Group of Pugwash Conferences on Science and World Affairs. Between 2004 and 2015 he also served as Chairman of the Danish Peace Academy. He founded the Journal of Bioenergetics and Biomembranes, and was for many years its Managing Editor. He also served as Technical Advisor to the World Health Organization, Regional Office for Europe (19881997).

    Until the early sixties, every house in the Belgian villages had a manual water pump, sourcing from a masoned individual water well. The water was free of charge, delicious and healthy (with a slightly different taste per region).

    Sometimes in the summer, the groundwater level got low. Neighbours helped each other out, despite being short in reserves in their own well.

    Then came progress, the wool washing and leather treating factories. They pumped mechanically and the underground water level sank. So individuals now had to drill deep for water and install electrical pumps. That worked for 5 years. Then came a notice from the administration to hook onto a public water distribution that was being established, because the ground water had become poisonous (the progress had progressed, you know…).

    So since the late 60’s, water there costs money.

    Exactly the same is happening currently on a global scale. What a shame.
