Nile Delta “Egypt”
•Nile Delta is about 25,000 km² with about 34 million inhabitants (Cairo is not included),
•It is among the most densely populated agricultural areas in the world, with 1,360
inhabitants per km².
•About half of the area is used for agriculture.
•The fish productivity is about 185000 Tons/year from the northern lakes (Maryut,
Manzala, Edkua and Burullus),
•About 40% of all Egyptian industry located in Nile Delta.
•Most of the investments and economic activities apparently go the delta region.

Lack of sanitation
Coastal erosion
•Egypt depends mainly on single water resources .
•The natural NILE cycle of flow and sediment discharge has been disrupted.
•The NILE DELTA is threaten by sea level rise erosion, sanitization, and pollution.
•There is a marked decline in agricultural productivity and loss of land and coastal lagoons at a time
•when the population is expanding exponentially.
Problem (1)
Competing uses of land
Needs for recommended new areas for population growth
Nile Delta is fairly unique in the distribution of its population, landuse and agriculture, and economic activity which makes it
extremely vulnerable to any potential impacts on its water
resources and coastal zone.
Adaptation assessment
Overview of Salam project
•It is planned to use 1.50 BCM/year of mixed water to irrigate the reclamation lands in
Port-Said Plateau, South Husseinia, and South Salhia.
• The first phase, covers about 165,000 Fed.
• The second phase covers the irrigation of 200,000 fed extending along the northern
coast of the Sinai Peninsula from Al-Arish westward.
• The last phase of the project is under construction at the present time and is expected
to be completed soon.
Problem (2)
Limited available water resources
Needs for reuse agricultural waste water
Water resources in Egypt are limited as Egypt is mostly a rainless country.
A gap between fresh water resources and the country's requirement already exists 6 BCM/year.
The possibility of increasing the fresh water resources from conventional sources is doubtful.

Problem (3)

Needs for protection of the coastal zone
Vulnerable areas defined by IPCC in 2006
Adaptation assessment
Beach nourishment and groins
Breakwaters
Legal development regulation

Cultivated Low Lands (1.5m - 2.5m Below Sea Level)
Problem (4)
Inefficient natural resources management
Needs for better water management
The NILE DELTA is threaten by pollution. There is a marked decline in agricultural productivity.
Drainage Catchments in the Delta with Pollution Problems
(1) Establishing in-stream Wetland
Adaptation assessment
(2) Establishing Manzala Wetland
(3) Monitoring water quality in Nile delta
(4) Establishing irrigation improvement program
(5) Enforce guidelines and law application for env. protección
􀂃Environmental Law No. 48 of 1982 & Law No. 4 of 1994.
Problem (5)
Salt water intrusion
The ground water is considered the third water source for irrigation and other human Uses.
The ground water reservoir in the Delta is considered to be one of the biggest reservoir in the world
( about 280 km3).
Due to the excessive pumping over the last few decades, the groundwater quality in the northern
parts of the Delta has been deteriorated considerably.
Needs for protection of coastal GW aquifer from excessive pumping
and pollution risk
Adaptation assessment
•Establishing monitoring programme according to priority areas in
Nile Delta.
•A 50 cm rise in the seawater level is expected to cause about 4.5 km
inland migration of equiconcentration line 1.
•Additional pumping should be practiced in the middle Delta and
pumping from the eastern and western parts should be reduced.
The challenge
The research project in Nile Delta is very important and must
be designed to solve the main problem (ecosystem degradation)
and address the following activities:
•Conducting actual scenarios on the effect climate change on
both the coastal areas and the Nile water availability.
•Adopting different measures, such as water recycling, and
exploitation of underground water resources to increase water
productivity.
•Using of modern irrigation techniques and genetically modified
seeds which grow with less water demands.
•Identifying new technology to be applied in water recycling
which resulted in the reduction of freshwater discharge to the
Mediterranean.
•Improving technical performance of water supply and deliver
system.
•
The challenge
• Adopting
different technologies for waterways, ponds, reservoirs
and lakes restoration.
•Reusing wastewater to support the agriculture production with
minimal risks to the ecosystem.
•Integrating biosystems to produce more products and generate
less waste.
• Groundwater and surface water bodies are physically interlinked;
and need to be managed in an integrated way.
•Adopting modern farming technology to increase crop-water
productivity and reduce pollutants.
•Providing guidance with regard to crop production, water
requirement and water quality.
Conclusion
The Nile Delta is one of the most heavily populated and intensely cultivated areas on earth.
It is highly vulnerable to environmental risks.
Sea level rise, soil and water degradation, undiversified crop-pattern, yield reduction,
pests and disease severity, and irrigation and drainage management are the main key
factors that increased the environmental degradation in that region.
It is vital to develop adaptation and upgrading awareness in the Delta region to deal with
such environmental risks.
