Transcript of WATER MANAGEMENT IN IRAQ...Iraq’s Climate Prospects Require Greater Coordination With Its...
Since the 1950s, Iraq and its “Fertile Crescent”
neighbors have experienced substantial changes in
weather patterns. These disruptions are expected
to continue—USAID and the World Bank anticipate
average annual temperature to increase around 3.6°
Fahrenheit (F) by 2050, accompanied by a 9 percent
decrease in average annual rainfall and a 22 percent
decrease in available runoff.1 Rising temperatures
and increased rainfall variability will intensify periods
of drought, reduce the availability of ground and
surface water, and increase the desertification
of arable land—crises that are compounded by
upstream dam construction in neighboring countries,
overconsumption of water, and persistent conflict.
This climate trajectory promises negative impacts on
Iraq’s agricultural production, human health, energy
extraction, and overall stability.
This issue of Maxar Spotlight highlights Iraq’s complex
climate-related challenges, and demonstrates
how Maxar Technologies’ satellite observations,
sophisticated automation, and advanced modeling tools
can augment climate forecasts, water management
policies, and infrastructure development.
Summary of Unique Tools & Applications
Global Weather Interactive (GWI) / Weather Desk™
GWI is an application within Weather Desk™, which serves
as the industry’s leading archive of global historical weather
information. GWI provides custom access to over 900 domestic
and 6,000 international weather stations for analysis of
temperature extrema, precipitation, and derived parameters
such as average temperature, average precipitation, and normal
departures for each.
Intermittent Water
Maxar’s Intermittent Water dataset uses Landsat imagery to
measure the change (30+ years) in observed water over a given
area. For this study, Intermittent Water was used to evaluate the
impact of climate change on Razazza Lake—an important source
for irrigation channels that feed Baghdad’s agriculture.
BaseVue
BaseVue is a standard global land cover dataset based on
Landsat, Sentinel-2, and Maxar imagery. BaseVue uses multi-
temporal, semi-automated classification to map cloud-free land
use land cover. For this study, agriculture land classification was
used to isolate satellite-detected wildfires over agriculture fields
for statistical modeling and hot spot analysis.

Iraq’s Climate Future: More Frequent Droughts, Water Shortages
Climate trend analysis from Global Weather Interactive
(GWI), an application within Maxar’s Weather Desk™
platform, projects decreased water availability for Iraq and
the surrounding region in the years to come. According
to analysis of 5-year and 30-year temperature and
precipitation data compiled from 13 weather stations across
the country, Iraq is experiencing consistently warmer
temperatures throughout the year with much hotter and
drier summers.
Rainfall trends are especially volatile. While rainfall averages
are up in recent years, this is due to intense and sporadic
rainfall events in certain parts of the country (most notably
in central and northeastern Iraq). Overall, water availability
is declining and demand is growing. These prospects are
concerning for a country that has struggled with multiple
conflicts, poor water management policies, and deficient
infrastructure.

Iraq’s Climate Prospects Require Greater Coordination With Its Neighbors
The majority of Iraq’s water resources are provided by the
Tigris and Euphrates rivers. Approximately 71 percent of the
two rivers’ discharge originates in Turkey, with an additional
7 percent from Iran and 4 percent from Syria. Only about
18 percent originates from watersheds located within
Iraq. To arrive at a comprehensive regional solution, donor
governments should consider a legislative framework for
riparian resource sharing between Turkey, Syria, Iran, and
Iraq. Increasing water shortages in downstream countries
and the environmental degradation that they’ve caused has
suggest the need for a robust diplomatic solution.
Water shortages in Iraq began in the 1970s, when Turkey
completed the first series of several dam projects on the
Tigris and Euphrates rivers. Based on 2018 estimates by
Iraq’s Ministry of Water Resources, the country has lost
approximately 30 percent of water volume previously
received from the Tigris and Euphrates rivers, and should
anticipate the loss of up to 50 percent of its riparian
resources as soon as 2030. The most significant dam
construction on the Tigris and Euphrates consists of
Guneydogu Anadolu Projesi (GAP) in southeastern Turkey. In
addition, Iran has significantly blocked, dammed, or diverted
three of the four major rivers it shares with Iraq.
Winter and spring are historically wet seasons in Kurdistan;
this intense rainfall is, however, difficult to harvest due
to northern Iraq’s low water storage capacity. Regional
experts warn that increased dam construction may not
represent a durable solution that warrants the negative
environmental and socio-economic issues associated with
new dams. Because of these diverse obstacles and water
challenges, decentralized and small-scale projects may
be more beneficial for water management in this region
including rain harvesting ponds, micro and submerged
dams, and water recycling plants.
One particular area that has experienced a significant
decline in water availability is Razazza Lake, located west
of Baghdad. Along with nearby Tharthar and Habbaniyah
Lakes, Razazza has been collecting rainwater and providing
irrigation channels to Baghdad’s agriculture for decades.
But the effects of climate change have impacted the area’s
water availability—and as such, more water is being pulled
from the lake system than is input. New channels have been
created to try and also preserve the fishing in Razazza
Lake, but droughts have been devastating.
Maxar’s Intermittent Water capability demonstrates how
satellite observations can be used to measure the impact of
climate change over a given area. The imagery time series
showcases the visual change to Razazza Lake between 1984
and 2013. The Intermittent Water layer displays the severity
of water loss over time by providing a measurement of how
often water was detected with each ground observation
over the past 30 years.

unique REGIONAL impacts of Rainfall Variability Across Iraq
Decades of intensive farming practices and poorly managed
water resources in Iraq—a nation which is more than 30
percent desert to begin with—have exacerbated water
shortages, reduced availability of ground and surface water,
and increased desertification of arable land. According to the
Iraqi government, over 100,000 donum (or around 25,000
acres) are lost each year to degradation. The impact of
droughts on the agricultural sector’s performance are viewed
as a primary driver of rural-to-urban migration and internal
displacement, particularly in western and southern Iraq.
Maxar’s GWI application and Weather Desk™ platform was
used to plot 5-year and 30-year averages across Iraq. This
analysis revealed that northeast Iraq receives the majority
of the country’s rainfall, with a monthly average of 1.3
inches over the past 5 years—a 13 percent increase from its
30-year average. In the past, precipitation was less intense
and occurred over extended periods of time. More recently,
heavy and unpredictable spring rains have damaged homes
and crops, and several people have been killed by the
flooding that followed. Experts anticipate that climate
change-related spring deluges will become increasingly
common in the region, while deforestation results in
mudslides and erosion of the most fertile layer of soil.
As is common in climate change scenarios, unpredictable
heavy precipitation is paradoxically accompanied by a
reduction on overall moisture availability. Traditionally, heavy
mountain snow gradually melted to fill Iraq’s rivers and lakes
and to replenish aquifers and groundwater resources.
Recently, lesser amounts of alpine snow have resulted in
reduced available water over time. Maxar’s Soil Moisture
analysis used satellite-derived data to measure the
volumetric soil moisture in the ground (up to 1,000
observations per pixel) through a time series of more than
30 years. The results confirmed anecdotal evidence of
substantially reduced soil moisture in recent years. This
kind of surface and groundwater resource monitoring will
be increasingly important for diversifying economic options
outside of oil production.
The situation in southeastern Iraq is different, though
certainly no less concerning. According to Maxar’s GWI
application and Weather Desk platform, southeastern Iraq
has experienced a 7 percent decrease in rainfall from its 30
year average. Water shortages and contamination in 2018
led to massive protests in the city of Basrah, a large
population center and primary oil hub in the south.
Waterborne illnesses from drinking water sourced from the
Shatt Al-Arab (formed by the confluence of the Tigris and
Euphrates rivers) resulted in over 100,000 hospitalizations
between August and November 2018.
Although the country’s coastline is small relative to total
area, the area’s low elevation and concentrated population
make the region especially vulnerable to climate change.

canals and waterways of Basrah have experienced

decreasing freshwater levels for the past several decades.
As water levels in the Tigris and Euphrates decline due to
dam building and decreased precipitation, salt water
intrusion from the Gulf increases. In 2018, seawater
intrusion contaminated the Chibayish freshwater marsh,
located in vicinity of Nasiriyah and Basrah approximately 100
miles upstream from the Persian Gulf. The marshes in the
area are an important environmental, cultural, and economic
resource. They serve as a natural filtration system that
protects the coastal fisheries in the Gulf, which accounts
for nearly 60 percent of fish consumed in Iraq.
The region has also experienced severe environmental
degradation from hostile conflict. In the early 1980s, President
Saddam Hussein punished the Marsh Arab tribes (who he
perceived as his opponents) by constructing a series of earth
barriers and diversion canals to dry the marshes. The
southern marshes were almost completely dry by 1991,
causing substantial sand dune creep towards former marshes
and increased coverage by sabkha (or salt flats).

In addition to climate change, the prolonged battle with
the Islamic State of Iraq and Syria (ISIS) has reduced
the agricultural production capacity in northern Iraq, the
country’s traditional bread basket. In the past several
years, ISIS has destroyed fields, fruit orchards, olive
groves, and beehives, as well as critical infrastructure like
irrigation networks, well pumps, generators, and power
electricity networks. Many areas that have been retaken
from ISIS have also seen a resurgence in violent attacks by
ISIS and ISIS-sympathizers.
ISIS’s tactics and remaining sympathizers have likely had
a significant part in the hundreds of fires that burned
across the country during this year’s wheat harvest
period. While the Iraqi government has downplayed the
group’s responsibility, ISIS specifically called for attacks
on farmland and disseminated guidance for building and
deploying improvised explosive devices to start fires. “Roll
up your sleeves and begin the harvest,” demanded ISIS’s

According to satellite-derived data and statistical modeling,
much of this year’s agricultural fires have occurred in

While agricultural production contributes minimally to Iraq’s
GDP (currently less than 5 percent), more than a third
of the country’s rural population relies on the sector for
employment. Revitalizing agriculture in the region is necessary
for the country’s future stability, and will require innovative
solutions that anticipate climate-related challenges.
Despite an overall increase in agricultural production
over the past decade, there are several concerning
trends. Northern Iraq (particularly Ninevah) is suffering
with continued conflict and poor infrastructure. The
predominantly rain-fed region of northern Iraq comprised 41
percent of the country’s total wheat production in 2008, but
is projected to supply only 13 percent in 2019. Central and
parts of southern Iraq have largely picked up the slack, with
central Iraq nearly doubling its percentage of the country’s
total output.
Because central and southern Iraq are increasingly reliant on
irrigation, there are significant concerns over water scarcity
Iraq’s Agriculture Output Increasingly Relies on Irrigation
and subsequent conflict over resources. During the massive
drought of 2018, residents in Maysan province accused
upstream residents in Wasit of using more water than they
had been allocated by Iraq’s Ministry of Water Resources.
Wasit residents rejected allegations of overuse, suggesting
the lack of water availability was due to drought conditions
and increased withdrawals of water upstream in Turkey. Tribal
leaders in Maysan have also been accused of diverting flows
from the Tigris illegally to irrigate their fields. The satellite
imagery on the following page depicts the location of illegal
freshwater tapping that was observed earlier this year in a
YouTube video at the Ktaiban canal in Basrah.
Iraqis have expressed frustration with the government’s
inability to control water quota distribution, excessive use
and illegal riparian withdrawals. More than 20 separate
violent altercations over water usage occurred in the
province of Dhi Qar alone in 2018—a warning to the Iraqi
government that large-scale conflict may erupt without
government intervention and resolution.

CONCLUSION
After decades of conflict, Iraqis are hopeful that rebuilding
and economic diversification are finally on tap. But there are
significant obstacles standing in the way of desperately
needed progress—and these challenges are being intensified
by the impacts of climate change. Desertification and
salinization of arable land, water shortages and declines in
water quality, decreased agricultural yields, and food
shortages are increasing competition for resources and
creating internal strife among already war-weary citizens.
Maxar‘s unique weather monitoring tools provide a
comprehensive approach for tracking, analyzing, and
predicting climate trends, and our Intermittent Water and
Soil Moisture datasets allow for extensive longitudinal
analysis of surface and sub-surface water levels. These
tools and subsequent analysis offer extensive insight that
can improve water management policy, agriculture
efficiency, and infrastructure planning—which will hopefully
produce quality-of-life improvements on the ground.
