MERIP Water in the middle East 2020 - 1 views
-
As a result of these climatic conditions, there is little surface water. The lines of rivers threading across the map of the region are few and far between. The arid climate also means that where there are stores of water below the surface, those aquifers are not being replenished very quickly. In some cases, aquifers are not being replenished at all; these fossil aquifers date back hundreds of thousands of years to past epochs when the region’s climate was wetter.

When it comes to water, the Middle East is a region of superlatives: the highest proportion of a population exposed to water stress, the least sustainable water resource use, the most water scarce region in the world. This simplistic narrative contains some truth.

The Middle East and North Africa also contains mountain chains where vegetation is lush and winters wet. Morocco’s Rif mountains, for example, receive over a meter of rainfall a year (for comparison, that is more than the Adirondacks). Around the Mediterranean Sea, too, climates are milder and rainfall higher. It sometimes snows in Damascus. Furthermore, even some dry parts of the region have significant water resources flowing through them, originating in wetter climes. Egypt’s southern city of Aswan, for instance, only receives 1mm of rainfall a year, but sits on the banks of the Nile, the longest river in the world. Depictions of the Middle East as water scarce, therefore, must be nuanced by an appreciation of the region’s varied geographies.

The particularly high growth rates in some countries—Iraq, Bahrain and Palestine—are not matched in all countries

The broad characterization of the region as water scarce and people rich, on the other hand, tells a simple and powerful story. It is a story that is reinforced by a commonly used indicator, the Falkenmark Water Stress Index. This easily calculable figure is a ratio of the total renewable freshwater resources available in a country to the number of people. If the index is less than 1,000 cubic meters per capita per year, it denotes a situation of water scarcity; if it is less than 500 cubic meters per capita per year, it indicates conditions of absolute water scarcity. According to this indicator, the region does not look good. Most of the countries are facing either scarcity or absolute s car ci t y.

Water scarcity is not so much about how much water there is and more about what it is being used f or

an archetypal Malthusian narrative. Eighteenth century scholar Thomas Malthus proposed that the combination of a limited resource base, only growing at an arithmetic rate, and an expanding population, growing at a geometric rate, would inevitably lead to a point where the system’s capacity to support that population was exceeded and crisis would result. This notion, so simplistic and yet so enduring, undergirds much of the writing about water in the Middle East
-
A larger population means more people drinking, cleaning their homes and bodies, washing clothes and cooking. These daily activities do not, however, require all that much water relative to other water uses
-
n annual allocation of 20 cubic meters per capita is sufficient to cover consumption and basic hygiene needs
-
In cities like Amman and Beirut, many neighborhoods only receive running water for a few hours a day; in war-torn Yemen, millions lack access to clean water. But the lack experienced by some is more due to the inadequacy of the infrastructures for delivering potable water and removing wastewater than the insufficiency of the resource per se
-
producing more food does not always require more water. There are techniques of applying water to the soil that are less water intensive, allowing for what water specialists term “more crop per drop.”
-
Agriculture consumes the greatest amount of water by far, globally. This pattern is particularly pronounced in the Middle East, where low rainfall across much of the region makes irrigation a necessity for cultivation. Agriculture uses 85 percent of the region’s water.
-
more about politics than population. The reason why Saudi Arabia long subsidized wheat production in the desert with water drawn from fossil aquifers, for instance, was not because it needed to produce more food for a growing population. Instead, this policy was about the government’s interest in becoming more self-sufficient so as to decrease its reliance on other countries and the associated vulnerabilities.
-
there is no direct correlation between population size and agricultural water use. Narratives of population-driven water crises should always be approached with caution
-
Many lower income residents, or people living in informal settlements, lack access to sufficient drinking water and sanitation. Populations in motion, too, can generate challenges for water managers. Refugee camps, for instance, which are amalgamations of people in spaces that were not necessarily designed to support those numbers, often struggle to provide enough water for their displaced population’s day-to-day uses.

Efforts to integrate climate change adaptation into water management plans are hampered by more pressing political priorities,

A number of countries in the Middle East and North Africa rely on transboundary water resources. The high degree of reliance is evident in an indicator known as the dependency ratio, which is the proportion of a nation’s freshwater resources—both surface and groundwater—that comes from outside that country. Syria and Iraq depend on the Tigris and Euphrates rivers, which rise in the mountainous region of southeastern Turkey. Egypt sources most of its water from the Nile, a river basin that spans 11 countries. Jordan’s two main surface water resources, the Jordan and Yarmouk rivers, are shared with its neighbors. Israel taps into surface and groundwater resources that traverse borders with the West Bank, Lebanon and Syria. Kuwait and Bahrain’s groundwater reserves are fed by water flowing laterally underground from Saudi Arabia.

available water resources of the Middle East and North Africa are also shifting due to anthropogenic climate change
-
Climate models are consistent in their projections that temperatures across the region are increasing and will continue to do so in coming decades. Higher temperatures mean higher evapotranspiration rates —plants, in other words, will drink more water—and larger losses from open surfaces like reservoirs. Demand from the most water intensive sector, agriculture, will increase.

the rise in sea level poses a risk of coastal flooding in deltas, like that of the Shatt al-Arab, on the border of Iraq and Iran, and the Nile Delta as well as other lowlying areas along the Mediterranean coastline

In the case of shared aquifers, the added uncertainties surrounding groundwater volumes and flows compound the challenges.
-
despite the dramatic appeal of the idea of a water war, most scholars agree that the concept is misleading. Wars typically have much more complicated origins than a single causal factor, like water. Intrastate disputes over water may be more significant than interstate conflicts. Moreover, a shared resource does not necessarily have to be a source of tension; it can be a source of cooperation
-
Countries in the more arid parts of the Middle East have championed technologies for producing more water. The Gulf states and Israel, for instance, have been leaders in desalination. In these countries, desalinated water now meets the majority of domestic water needs

Many of the region’s water bodies are contaminated with sewage, agricultural chemicals and industrial waste,
-
Public awareness campaigns urge residents to conserve water, take shorter showers, turn off the faucet when brushing their teeth, not leave the water running when cleaning dishes and avoid washing their cars
-
Although initiatives are underway to develop solar-powered desalination, these projects are still in their infancy
-
In many countries of the region, farmers reuse agricultural drainage water. If municipal and industrial waste is properly treated, it too can be reused
-
experts have advised authorities to raise the price of water. In most countries of the region, water is priced significantly below its cost of delivery. In some cases, it is free. Egyptian farmers, for instance, do not pay for the water they use on their fields (although they do pay other irrigation-related costs, such as energy for pumps). If they had to pay for water, economists argue, they would not use so much
-
While these measures can be effective at reducing water consumption and easing scarcity, they impose costs and can increase rural poverty without other forms of social protection and support for small farmers. They also risk ignoring the larger contextual factors that shape water use in a home, factory or farm. Policies that seek to mandate a technology, price or behavioral change for the sake of saving water, without recognizing the priorities and perspectives of those who use this water on a daily basis, are unlikely to be successful
-
the challenge of water scarcity and the experience of many within the region who struggle to find sufficient, clean water for their everyday needs and livelihoods is as much about economic priorities, social inequalities and political relations as it is a function of the region’s geography
