  • Gaza's aquifer and only natural freshwater source is "in danger of collapse," the UN is warning.
  • The plant is handling twice its capacity and is only able to partially treat the sewage.
  • In addition, with several years of drought and the digging of hundreds of illegal, unregulated wells, the UN Environmental Programme says at least three times more water is extracted than is replenished each year.

  • only 5-10% of the water in Gaza's wells - and therefore its taps - now meets World Health Organization guidelines, even after it has been chlorinated.
  • "It's like sea water," says local resident Shadi Dosh, 27.
  • Another concern is the blood disorder dubbed "blue baby syndrome", which is associated with nitrate pollution.
  • Thirty kilometres of pipes and 11 wells were damaged, and sewage flooded for up to a kilometre after one waste water plant was hit.

  • Qatar's leading news outlets recently reported that local agricultural production has jumped by 400% since a political and economic blockade was imposed on the emirate by its Arab neighbors in 2017. And within a few years, 40% to 50% of fresh products could be produced locally,
  • the blockade caused Qatar to realize its vulnerability when it comes to the food supply
  •  recently ranked as the most water-stressed country in the world. It is also one of the few countries with no permanent rivers as rainfall is extremely unpredictable and highly erratic

  • Qatar’s fast-growing agriculture has been looking deep underground for its water.
  • Each year, 92% of the 250 million cubic meters (75,000 acre-feet) of groundwater withdrawn from the country's aquifers is given free of charge to farmers
  • At Baladna, Qatar's largest producer of fresh dairy products, 12,000 cows produce 400 tons of fresh milk and and other dairy goods a day. The company’s press officer, Saba Mohammed Nasser Al Fadala, acknowledges that "cows were not made for the desert."
  • Artificial recharges and irrigation return flows reduce this loss but also may be polluting the aquifers, in part because of chemical fertilizers used by farmers
  • groundwater depletion causes seawater intrusion into aquifers: In 2014, 69% of wells in Qatar were classified as moderately saline
  • Half of the groundwater allocated to agriculture is utilized to grow fodder that feeds 60% to 70% of the 1.6 million head of livestock in Qatar.
  • Qatar withdraws nearly four times as much water from its aquifers than is replenished by rainfall each year
  • To mitigate the depletion of Qatar’s aquifers, local authorities plan to ban the use of groundwater to grow fodder by 2025 and restrict it to vegetable crops. Treated sewage water that is currently allocated to the irrigation of green spaces, deep injection into aquifers and agriculture is to be used for fodder.
  • Freshwater reserves for Qatar are estimated at 2.5 billion cubic meters. However, an annual groundwater deficit of some 100 million cubic meters or more puts Qatar's future in a precarious situation
  • each Baladna cow requires an average of 700 liters of water a day, most of which is used for misting in Qatar's heat. The press officer said up to 80% of this water can be recycled
  • The Ministry of Municipality and Environment says it supports those who reduce their groundwater consumption and move toward hydroponic farming. A budget of $2.75 million to $3.3 million has been allocated to a program that aims to provide up to 140 farms with free greenhouses

MERIP Water in the middle East 2020 - 1 views

MENA water agriculture food security WaterSecurity climate analysis economy

  • 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
  • Migration and forced displacement also shape population distributions.
  • 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.
  • food imports can be seen as a source of “virtual 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.
  • studies suggest that the variability and uncertainty in rainfall timing and intensity is increasing
  • 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
  • These uses are so small relative to agriculture, though, that their impact is limited.
  • 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

Egypt water agriculture food land climate COP sustainability SDGs

  • Adel Abdullah cultivates a subsistence living off of six acres of peppers, eggplants, cucumbers, tomatoes, wheat, corn, and pomegranates. He is one of millions of smallholder farmers working in the Delta. He walks barefoot in his farm as a show of reverence to the land. The soil is pale and thin, almost as sandy as the beach, and choked by mounting concentrations of salt, left behind by periodic coastal flooding and pushed into underground aquifers by the rising sea.“This is the first place to be affected by climate change,” Abdullah says. “The barriers help a bit with flooding, but the salty soil is still really killing us.”
  • he takes irrigation water from the nearby Kitchener Drain, one of the largest and most polluted canals in Egypt that aggregates wastewater from the farms, businesses, and households of an estimated 11 million people in the Delta. By the time water reaches Abdullah’s farm, it may have been reused half a dozen times since entering Egypt in the Nile, each time accumulating more salts and pollutants and losing beneficial nutrients.
  • Abdullah is forced to douse the farm in fertilizers, pesticides, and salt-suppressing chemicals, all of which further degrade the soil. Those inputs, on top of the rising costs of irrigation systems and machinery, eat up any potential income Abdullah might earn

  • The Nile Delta—where agriculture employs one-fifth of the country’s workforce and is responsible for 12% of its GDP and much of its food supply—is being hammered by rising sea levels, rising temperatures, and a growing shortage of water.
  • rapid urbanization and population growth
  • Climate adaptation solutions that could keep environmental problems from turning existential—fixing the battered and wasteful irrigation network, expanding affordable access to improved seeds and climate-smart farming technologies, and more effective and equitable regulation of urban development on agricultural land—are being rolled out by the government and research groups, but often slower than the pace of climate impacts. That’s left Egypt’s economy and food security exposed to growing risk.
  • “We’re really squeezed and marginalized here, and the government isn’t helping,” said one farmer down the road from Abdullah, who requested anonymity to speak frankly (with tens of thousands of political prisoners, Egypt’s restrictions on free speech are also gaining prominence ahead of COP27).
  • his children see no future in agriculture
  • Around 1805, an Ottoman general named Muhammad Ali took control of the country, and founded the dynasty of kings that would rule—eventually under British colonial supervision—for 150 years. One of Ali’s most enduring marks on the country was the establishment of the first modern network of dams and irrigation canals in the Delta, which allowed tens of thousands of new acres to come under cultivation.
  • water and land played a crucial role in Nasser’s legacy. 12% of the country’s arable land was owned by the aristocracy; Nasser nationalized this land and distributed it to about 340,000 impoverished rural families. He also further extended Ali’s irrigation network and oversaw construction of the Aswan High Dam, which brought an end to the Nile’s ancient seasonal flooding and fixed the river in its present position, with just two remaining branches forking through the Delta.
  • Egypt’s population has since more than quadrupled, to 104 million. Yet the flow of the Nile, which supplies more than 95% of the country’s water, has remained more or less constant. In the 1990s water availability fell below the international “water poverty” benchmark of 1,000 cubic meters per person per year.
  • Egypt has managed that scarcity by meticulously recycling agricultural water and, in recent years, curtailing the production of water-intensive crops like cotton and rice and importing 40% of its wheat and other food staples.
  • The population is still growing quickly, and could reach 160 million by 2050. The Grand Ethiopian Renaissance Dam that is nearing completion upstream could cut the flow of Nile water into Egypt by a quarter during the as-yet-unknown number of years it will take to fill its reservoir. By 2100, climate change-related heat waves upstream could reduce the Nile’s flow by 75%, Abousabaa said.
  • rising temperatures and falling rainfall mean crops—which consume 86% of Egypt’s water supply—will require more irrigation to survive.
  • current annual demand for water is about 35% higher than what the country receives from the Nile, groundwater, and a very small amount of rain—a deficit of about 20 billion cubic meters. To cover it, she said, Egypt will need to use every drop multiple times, aggressively minimize wastage, and boost the supply by investing $2.8 billion in dozens of new desalination plants with the aim to produce 5 billion cubic meters annually by 2050.
  • The unpredictability makes it difficult to identify solutions, Salah says: “Climate change is like a big black box.”
  • On the western fringe of the Delta, farms and suburbs are gradually overtaking the desert as the central Delta grows more crowded. Here, water is even scarcer and the impacts of climate change are more pronounced. But in this and a few other desert areas around Egypt, the government is working to link more than 1.5 million acres to groundwater irrigation, and says it is about one-third of the way there. Land reclamation could take some pressure off the Delta, and sandy soils are well-suited for the production of citrus fruits that are one of Egypt’s most lucrative exports.
  • “For the last two years, with heat wave after heat wave, we lost more than half the crop. It’s really sad.”
  • The farm relies on groundwater brought up from wells on the property, and Nasrallah says the suburbs are draining the aquifer. In the last four years he has had to dig an extra thirty meters to find water—and deeper wells mean higher electricity bills for pumping. Some wells have dried up altogether. Recently, government officials told him he had to stop watering the grass on a soccer field he built for his workers.
  • Urbanization is also spreading in the inner Delta, as many farmers decide that constructing housing is more profitable than growing crops. Since the 1970s, about 14% of the Delta’s arable land has been converted to urban development
  • Individual farms are also becoming smaller with each generation as, in keeping with longstanding Egyptian custom, land is divided among a father’s heirs (with sons traditionally taking a larger share than daughters). Urban development degrades the Delta’s soil and drives more farming into the desert, leaving the entire food system more vulnerable to climate impacts. Land fragmentation leads to the inefficient use of water and other resources and raises the costs of distribution for farmers.
  • in some cases, the government’s own plans are responsible, most recently in August when thousands of people living on a Nile island near Cairo that was primarily used for farming were evicted to make way for a state-sanctioned development project.
  • The network started by Muhammed Ali now includes about 33,000 miles of delivery and drainage canals across the country, enough to wrap around the globe, that range in size from small rivers to something a child could hop over. Delta residents say they used to bathe in these canals, drink from them, and raise fish in them. Now many of them, especially at the ends of the network, are polluted with farming chemicals and sewage, and choked with trash.
  • Between seepage, evaporation, and water wasted by farmers who flood their fields instead of using controlled irrigation hoses, nearly one-third of the country’s water is lost in the irrigation system between the Aswan High Dam and the sea
  • The soil is dark and appears rich, but is crusted with a visible layer of salt, a problem that affects up to 40% of Egypt’s arable soil.
  • Fixing the irrigation network is a priority for the government. Eman Sayed from the Irrigation Ministry said her agency has lined about 3,700 miles of canals with concrete in the last two years and is aiming to finish another 12,400 in the next few years. The ministry is also helping farmers cover the cost of installing drip irrigation systems, which researchers at AUC found can cut farmers’ water consumption 61% per year; today such systems cover only one-sixth of arable land in Egypt.
  • Authorities have also begun to restrict production of water-intensive crops like rice and bananas, although farmers say there is little enforcement of these rules, and both crops are still widely cultivated throughout the Delta.
  • Egypt has made clear that COP27 will focus primarily on wringing climate finance out of the rich countries that are most responsible for climate change.
  • On the horizon, an offshore natural gas platform is visible. Egypt, which seized the disruption of Russian energy supplies to Europe because of the Ukraine war as an opening to boost its own exports of natural gas, is now contributing more to the problem than ever before; an independent review of its new climate strategy ranked it “highly insufficient” for averting disastrous levels of carbon emissions.
  • By 2100, Noureldeen says, sea level rise could inundate nearly 700 square miles of the coastal Delta and displace four million people.
