While climate change has captured the headlines, many countries are running out of freshwater supplies, threatening human health and causing conflicts between nations.

 

Water should be at the top of the global and national agendas.

In recent years, climate change seems to have elbowed out other environmental issues to become the No. 1 global problem. But the alarming problems of water - increasing scarcity, lack of access to drinking water and sanitation, pollution, flooding - are equally important and an even more immediate threat.

On 28 July, the UN General Assembly in a historic decision recognized the right to water and sanitation as a human right. This is a fitting recognition of the crucial importance of water to the survival of individuals and the basis for development of nations and indeed the world.

The extensive floods in Pakistan is also a current reminder of two things: the devastating impact of climate change on rainfall and the flow of water quantities; and the importance of properly managing water drainage, especially in the major rivers and waterways.

The increasing shortage of water in many countries has become a crisis.

 

A decade ago, it was predicted that a third of the world’s population would be facing water scarcity by 2025. But this threshold has already been reached. Two billion people live in countries that are water-stressed and by 2025, two-thirds of the world population may suffer water stress, unless current trends alter.

Even more dramatic, it is predicted that wars will be fought over water this century, just as wars were and are still being fought over control of oil these past decades.

“The global population tripled in the 20th century but water consumption went up sevenfold," noted Maude Barlow of the Council of Canadians and an expert on the global water crisis in her book Blue Covenant.

“By 2050, after we add another 3 billion to the population, humans will need an 80% increase in water supplies just to feed ourselves. No one knows where this water is going to come from.”



Loss of water supplies

There is a rapidly growing demand for freshwater but its supply is limited and decreasing.

Water supply is affected by the loss of watersheds due to deforestation and soil erosion in hills and mountains. There is also a severe depletion of valuable groundwater resources as water is taken up for agriculture and industry, and is being dug from deeper and deeper sources.

Mining of groundwater has caused the water-table to drop in parts of many countries including India and China, West Asia, Russia and the United States.

Agriculture uses 70% of water because industrial agriculture requires large amounts of water. It takes 3 cubic meters of water to produce a kilo of cereals, and 15 cubic meters of water to produce a kilo of beef because of the grain fed to the cows.

A lot of surface water is also polluted and thus not available for human use, or if it is used, the polluted water causes health problems. Five million people die from water-borne diseases annually.

Water supplies are also being affected by climate change. Global warming is causing an 'accelerated' melting of the glaciers and there will be less glaciers in the future.

For example, the Himalayan glaciers feed many of the great rivers in India, China and Southeast Asia,

“The full scale glacier shrinkage in the plateau regions will eventually lead to an ecological catastrophe,” according to Yao Tandong of the Chinese Academy of Sciences.

The acute water problems facing Yemen are described in the London-based Guardian on Feb 27.

The country’s capital Sana’a is predicted to run out of water in 2017 as four times as much water is taken out of its river basin as falls into it each year. Of the country’s 21 main water aquifers, 19 are no longer being replenished after a drought and increased demand.

The water situation is so serious the government has considered moving the capital as well as desalinating coastal seawater and pumping it 2,000 meters uphill to Sana’a.
 

 


Conflict over water supplies

Water scarcity has also become a reason for conflict.

 

This is especially when a source of water such as a major river serves more than one country. The country or countries that have the upper reaches of the river can affect the volume of water flowing into the countries at the lower parts of the river.

In Africa, about 50 rivers are each shared by two or more countries. According to an issue of Population Reports, access to water from the Nile, Zambezi, Niger, and Volta river basins in particular has the potential to ignite conflicts.

It also describes how the Aral Sea Basin in Central Asia is beset by international conflicts over water among Turkmenistan, Uzbekistan, Kazakhstan, Kyrgyzstan, and Tajikistan which all depend for their survival on the waters of the Amu Darya and Syr Darya rivers.

The Middle East has been running out of water. In that situation the grounds for conflict have increased. In his recent book Water, Steven Solomon describes the growing tension over the sharing of water resources of the Nile especially between Egypt and Ethiopia.

In the Jordan River basin, writes Solomon,

“in one of the world’s political hot spots, Israelis, Palestinians, Jordanians and Syrians contest to control and divide the scarce resources of a region that long ago ran out of enough freshwater for everyone.”

There can also be similar competition for water within a country, for example between states that share the same river.

According to Population Reports, in the western US, farmers who want more irrigation water face off against urban areas that demand more water for households and other municipal uses.

In India, Karnataka state was in a water dispute with Andhra Pradesh over the height of a dam on the Krishna River, which could affect the amount of water available for use by both states.
 

 


Private vs. Public control over water systems

Another issue is the fight over the systems for owning and distributing the scarce water resources. In her book, Maude Barlow describes the recent policies to privatize water, which until recently was under direct control of government authorities.

Privatization was first carried out in Western countries and then spread to developing countries through World Bank loans and projects.

This has led to adverse effects on people’s access to water, according to Barlow, who also documents the fight by citizen groups in many countries to make water a public good, and to make access to water a human right.

Water as a top priority issue

All the above issues should be taken with the same seriousness as climate change, because water is about the most important item needed by everyone, and its scarcity affects both human health and geo-politics.

As Solomon puts it:

“An explosive new political fault line is erupting across the global landscape between the water Haves and water Have Nots… Simply, water is surpassing oil itself as the world’s scarcest critical resource.

 

“Just as oil conflicts were central to the 20th century history, the struggle over freshwater is set to shape a new turning point in the world order and the destiny of civilization.”

Thus, water must be recognized as a crisis issue and solutions to the crisis should be at the top of the global and national agendas.

It is thus timely that the United Nations General Assembly, the world’s top policy forum, has adopted the resolution that the right to water and sanitation is a human right.

 

Operationalizing this right so that all human beings have access to water, and that all countries have the capacity to obtain, manage and wisely use water resources, is an imperative.
