By Joannah Otis for NWNL

This is the sixth of our blog series on the Nile River in Egypt by NWNL Researcher Joannah Otis, sophomore at Georgetown University. Following her blogs on the Nile in Ancient Egypt, this essay addresses the importance of trees and indigenous flora to Ancient Egyptians. [NWNL has completed documentary expeditions to the White and Blue Nile Rivers, but due to current challenges for photojournalists visiting Egypt and Sudan, NWNL is using literary and online resources to investigate the availability, quality and usage of the main stem of the Nile.]

2nd blog 2Willow Tree

Trees played a symbolic role in early Egyptian life as they were associated with both Ra, the sun god, and Osiris, god of the afterlife. Sycamore trees were thought to stand at the gates of heaven while the persea tree was considered a sacred plant. According to ancient myths, the willow tree protected Osiris’s body after he was killed by his brother Set. These trees and others served as physical manifestations of the gods that Egyptians worshipped. Their importance speaks to the dependence this civilization had on the indigenous flora of the Nile River Basin.1

Historic records indicate that Ancient Egypt developed a forest management system in the 11th century CE, but later tree harvesting eliminated much of these forests. This, along with the gradual transition to a dryer climate in Egypt, spelled the demise of the sacred persea tree.2  Sometimes referred to as the ished tree, it was first grown and worshipped in Heliopolis during the Old Kingdom, but later spread its roots in Memphis and Edfu. It is a small evergreen tree with yellow fruit that grew throughout Upper Egypt. Egyptians held that the tree was protected by Ra in the form of a cat and closely associated it with the rising run.3 The persea was believed to hold the divine plan within its fruit, which would give eternal life and knowledge of destiny to those who ate it. To the Egyptians, the tree’s trunk represented the world pillar around which the heavens revolved. It was also considered a symbol of resurrection and many used its branches in funerary bouquets. The persea tree no longer grows in Africa, likely because the climate is dryer today than it was in the time of the Ancient Egyptians.4

The willow tree has grown in Egypt since prehistoric times and is usually found in wet environments or near water. Today, its timber is used for carving small items, but centuries ago, its branches were strung together to form garlands for the gods. Willow leaf garlands in the shape of crowns have also been found in the tombs of pharaohs, including Ahmose I, Amenhotep I, and Tutankhamen, to align them with Osiris.5 After being murdered by his brother Set, Osiris’s body was placed into a coffin and thrown into the Nile River. Around this coffin, a willow tree sprang up to protect the godly body. Towns with groves of willow trees were believed to house one of the dismembered parts of Osiris and thus became sacred spaces.6

Although of lesser importance, the sycamore tree was also considered a sacred plant. It was generally thought of in relation to the goddesses Nut, Hathor, and Isis who were sometimes depicted reaching out from the tree to offer provisions to the deceased. As a result, sycamores were often planted near graves or used to make coffins so the dead could return to the mother tree goddess.7 Other significant trees include the Tamarisk, which was sacred to Wepwawet, and the Acacia tree, which was associated with Horus.8 Each of these trees contribute to the great biodiversity of the Nile River Basin and served religious purposes for the Ancient Egyptian people.

Nile River Flora

January 10, 2018

By Joannah Otis for No Water No Life (NWNL)

This is the 5th blog in the NWNL series on the Nile River in Egypt by NWNL Researcher Joannah Otis, a sophomore at Georgetown University. This essay addresses the history and uses of the most prevalent types of flora growing in the Nile River Basin. [NWNL has completed documentary expeditions to the White and Blue Nile Rivers, but due to current challenges for photojournalists visiting Egypt and Sudan, NWNL is using literary and online resources to investigate the availability, quality and usage of the main stem of the Nile.]

The Nile River is home to thousands of species of flora, many of which were vital to the livelihoods of Ancient Egyptians. Aside from growing crops for consumption, Egyptians have long grown plants like cotton, papyrus, and flax for commercial purposes. The diversity and extent of plant life in Egypt is a tribute to the Nile River’s incredible life-giving capacity.

Egyptian cotton is perhaps the most well-known plant product to emerge from the African continent, although the modern variety was not cultivated in Egypt until 1821 when ruler Mohamed Ali Pasha discovered that his country’s climate was perfect for growing cotton. It should be noted, however, that the native variety (G. herbaceum) was first cultivated by Pliny in first century CE Nubia. By 1869, cotton production had expanded significantly to meet the demands of European textile factors in the wake of the American Civil War. Both the completion of the Suez Canal in 1869 and the completion of the Aswan High Dam in 1970 benefitted the cotton trade. While the canal made trade easier and more accessible, the dam protected the cotton from flooding and allowed for the expansion of its cultivation by providing regular irrigation. Today, Egypt remains a significant exporter of cotton to countries all over the world.1

In Ancient Egypt, the linen made from flax was a universal fabric that every citizen wore regardless of class. Linen is still grown in Egypt, although it is no longer the sole clothing material worn. Considered to be a symbol of purity and divine light, linen was a sacred cloth used to mummify the dead. It was also used to make sails and as a form of payment. The earliest example of Egyptian linen dates from 4500 BCE. Towards the end of the Egyptian civilization, the government established linen production centers staffed by slave laborers. Since everyone wore linen, class was differentiated by the fineness of the weave and the number of layers worn; the more important the person, the finer the weave and the more layers they wore. Flax was not only a source of wealth, but also a signifier of it.2

Although papyrus no longer populates the banks of Egypt’s Nile River due to human overexploitation, it was once a plentiful crop that served several purposes for the Ancient Egyptians. Papyrus thrives in shallow fresh water or water-saturated areas, so the Nile Delta marshes and low-lying areas of the Nile Valley were home to dense thickets of the plant. It was harvested to make skiffs used for hunting, pilgrimages, local transport, and funerals as well as to make writing surfaces. This early form of paper was created under heavy pressure from layers of pith found inside the stalk. Fortunately, Egypt’s dry climate has preserved many early papyrus documents, which indicate that the surface was used for letters, legal texts, religious narratives, illustrations, contracts, and administrative documents. The earliest of these dates from c. 2500 BCE and was discovered at Wadi el-Jarf, a Red Sea port. A blank roll of papyrus dating from c. 2900 BCE was also found in the tomb of a high official named Hemaka. These preserved papyri are significant because the surface was often erased and reused several times.3 The cultivation and use of papyrus for writing material ceased in the 9th century CE when paper from other plant fibers became more popular.4

Papyrus also played a significant role in the Ancient Egyptian religion as the marshes where it grew were considered fertile areas containing the seeds of creation. According to Egyptian myth, the goddess Isis hid her son in the papyrus thickets of Lower Egypt after her brother Seth murdered her husband Osiris. This infant, Horus, was raised amongst the papyrus by the goddess Hathor who was depicted as a cow emerging from papyrus thickets and was worshipped in the Shaking of the Papyrus ritual. Wadjet, the protector goddess of Lower Egypt, was similarly shown carrying a scepter made of papyrus. The ceilings of temples and tombs were often supported by columns whose capitals resembled the tops of papyrus plants. To the Ancient Egyptians, papyrus thickets were symbolic of chaos surrounding and threatening their world as the tickets often hid dangerous creatures such as hippos and crocodiles. Nonetheless, papyrus played an indispensable role in early Egypt.5

Aside from flax, cotton, and papyrus, Ancient Egyptians grew numerous other crops. These included barley, fava beans, lentils, lettuce, peas, onions, cucumbers, melons, radishes, emmer, wheat, barley, wheat, leeks, grapes, chickpeas, dill, and sesame. Present-day Egyptians continue to harvest these crops with the exception of emmer, which was not grown after the Roman Period, and barley, which also declined after the Roman Period as a result of the popularity of wine over beer. The wide variety of flora found in Egypt speaks to the lushness of the Nile River Basin.6

Hippos, Crocodiles and Snakes – Oh My!

December 12, 2017

By Joannah Otis for No Water No Life 

This is the fourth in our blog series on The Nile River in Egypt by NWNL Researcher Joannah Otis, sophomore at Georgetown University. This essay addresses the significance of the most prevalent species of fauna living along the Nile River Basin in Ancient Egypt. [NWNL has completed documentary expeditions to the White and Blue Nile Rivers, but due to current challenges for photojournalists visiting Egypt and Sudan, NWNL is using literary and online resources to investigate the availability, quality and usage of the main stem of the Nile.]

Animals played a significant role in Ancient Egyptian life as pets, hunting partners and religious embodiments of various gods. Wildlife in the Lower Nile River Basin served as physical manifestations of deities, allowing early Egyptians to foster a closer connection to their gods.1 Their importance is evident from the hundreds of animal mummies found in tombs of the pharaohs and officials.  Hippos and crocodiles, due to their size and potential for harm to boats and laborers on the Nile River banks, were worshipped in the hopes that they would not bother humans.

Ancient Egyptians attempted to placate hippos by giving offerings to the goddess Taurent, depicted as a pregnant hippo since she was believed to be the goddess of fertility.2 The most famous Egyptian hippopotamus today is found at the Metropolitan Museum of Art and nicknamed “William.”  Residing in the museum since 1917, William has become an endearing mascot of the institution. He was molded in faience, a ceramic material of ground quartz, during the Middle Kingdom circa 1961-1878 BCE in Middle Egypt. His blue-glazed body is decorated with river plants indigenous to Egypt.  

Since hippos were thought to reside in the waterways along the journey to the afterlife, they were considered as an animal to be respected both in life and in death. This is evidenced by William’s three broken legs, which were purposely maimed to prevent him from harming the deceased.3 

As well as wild animals, domesticated animals, such as sheep, cattle, horses, cats and dogs doubled as objects of religious worship. Sheep were employed to trample newly-sown seed into flooded plots of land, in addition to providing their owners with wool, skins, meat and milk. Thus rams, associated with Amun the god of Thebes and Khnum the creator god, were interpreted as signs of fertility.  Cattle were similarly prized and imported as war spoils. Horses, introduced to Egypt around 1500 BCE, became symbols of wealth and prestige due to their rarity before breeding programs developed. Chariots pulled by a pair of horses were used for ceremonies, hunting, and battle.4

Cats became perhaps the most popular pets and sacrificial objects for the Ancient Egyptians after their domestication between 4000 and 3500 BCE. They were closely associated with the fertility and child-rearing goddess Bastet. Many families would sacrifice female cats in the hopes of becoming pregnant. It is believed that some temples kept cats on their premises strictly for the purpose of providing worshippers with an easy offering.  As well, cats were kept as pets to prevent mice, snakes and rats from ruining precious Nile River crops and food sources.4 Similarly, dogs were kept as pets, for hunting and for guard duty.5

Less friendly felines and other ferocious wildlife on the floodplains were given reverence for their ability to cause harm.  Offerings were made and prayers were uttered in the hopes that dangerous wild animals would not cause trouble for their human neighbors sharing the same riverbanks. Cheetahs, as well as other large cats such as lions, were hunted for their prized furs, but also captured and kept as house pets. Such highly-regarded animals were aligned with the pharaoh, who was described as fearless and brave as a lion. Nile River crocodiles were given a divine status and associated with the god Sobek so as to give them an incentive to avoid humans. Given that these crocodiles could grow up to six meters long, it was important for the Egyptian people to feel that they had some sort of defense against them.

Snakes also were cause for caution as the poisonous Egyptian cobra and the black-necked spitting cobra had fatal venom. These snakes became protectors of the pharaoh and were often depicted poised on his brow.7 Although some animals were worshipped because they were feared, others were simply associated with important matters of life like fertility or bravery. All of these creatures, however, were vital to the religious livelihoods of the Ancient Egyptians, as well as to the Nile River Basin’s ecosystem.

Seeking Nile River Origins via its Tributaries

November 21, 2017

By Joannah Otis for No Water No Life

This is the third blog on the Nile River in Egypt by NWNL Researcher Joannah Otis, sophomore at Georgetown University. This essay addresses the sources of the Nile  – lakes, tributaries, and a great swamp. [NWNL has completed documentary expeditions to the White and Blue Nile Rivers, but due to current challenges for photojournalists in Egypt and Sudan, NWNL is using literary and online resources to investigate the main stem of the Nile.]

For centuries, the debate over the source of the Nile River incited explorations and evoked endless questions. The Ancient Egyptians believed that the Nile originated from an underground sea or spring, but never ventured upriver to confirm their theory.  Instead they put their faith in Hapi, god of the Nile River.1 [See NWNL Blog “Finding Hapi-ness on the Nile,” .]

Interest in the elusive source arose again c. 440 BCE when Herodotus wrote in The Histories of the “fountains of the Nile.”  He asserted that melting snow from upstream mountains flooded the headwaters to create the seasonal inundation.2  It was not until 1768 when James Bruce began searching for and ultimately found the source of the Blue Nile at Lake Tana in the Ethiopian Highlands that some light was shed on the issue.  

In 1874, Henry Morton Stanley confirmed an earlier theory by John Hanning Speke that Lake Victoria was the source of the White Nile. These explorers and many others were often sponsored by the Royal Geographical Society in England and driven by their own hopes for fame.3 Today’s satellite technology and advanced resources have enabled us to positively identify Lake Tana as the source of the Blue Nile and Lake Victoria as the source of the White Nile. These two main rivers meet in Khartoum, Egypt to form the great Nile River.

The Blue Nile is the source of about 85% of the Nile’s water.4 Beginning in the Ethiopian Highlands where a plateau of basalt lava receives rain from seasonal monsoons from May to October, the Blue Nile stretches over 900 miles into Sudan. This origin point lies 2,500 meters above sea level.  Beginning its northbound route, this river flows through Lake Tana, as well as the Blue Nile Gorge.5 Lake Tana is a shallow body of water measuring 1,400 square miles, surrounded by the Amhara tribe’s ancestral lands.6 The Blue Nile Gorge, lying on the edge of Africa’s Great Rift Valley, guides the Blue Nile for 370 miles into the middle of the Ethiopian Highlands.7

While the White Nile contributes only 15% of the Nile River’s water, it is still an important ecological and hydrological presence.8 Originating in Lake Victoria and fed by the Ruvubu, Nyabarongo, Mara and other rivers, the White Nile flows through Lake Kyoga, Lake Albert, and the Sudd.9 The White Nile flows through much of the Albertine Rift Region.  It spans from the northernmost point of Uganda’s Lake Albert to the southern tip of Lake Tanganyika.10  This rift is home to a plethora of diverse wildlife, including 5,793 plant species, which brings profitable tourism to Uganda. Between Juba, Ethiopia and Khartoum, the river in Sudan drops just 75 meters. To the east and west of the river, the floodplains become savannah and then desert as lush growth that adorns the Nile’s banks disappears.11

Just south of Khartoum, lies the vast Sudd, covering most of  South Sudan. Meaning ‘obstacle’ in Arabic. the Sudd is one of the world’s largest wetlands and the Nile Basin’s largest freshwater wetland.  The Sudd is a 12,355 square-mile practically impenetrable swamp of complex channels and lagoons –  an explorer’s challenge.  Fed by heavy rainfall from April to October,12 it provides floodwater storage and water habitat for 350 plant species, 470 migratory bird species, and 100 fish species.  Antelope migrations from the surrounding arid Sahel retreat annually to the Sudd in astonishing numbers.  Around 1.2 million white-eared kob, Nile Lechwe, and tiang, as well as wild dogs, crocodiles and hippos in the Sudd are best viewed by air.   The Sudd is also the home to pastoralist Nuer, Dinka and Shilluk tribes, Nilotic peoples who practice subsistence semi-nomadic cattle breeding and some grain farming.

Ecosystems within the swamp include open waters with submerged vegetation, floodplain shrubland, surface-floating fringe vegetation, seasonally flooded grassland and woodland.13 Since most of the water that enters the Sudd evaporates due to high temperatures in Sudan, the White Nile leaves this swamp with half the power with which it enters.14  Since the 1930’s, there’ve been proposals to build a canal, today referred to as the Jonglei Canal Project, east out of the Sudd directly to the main stem of the Nile River.  It is said such a canal could increase Egypt’s water supply by five to seven percent. While Sudan and Egypt would benefit, South Sudan would see its fisheries die, grazing lands dry out and groundwater lowered.

After years of searching, the sources of the Blue and White Nile River are no longer mysteries. The number of plant and animal species who depend on them are staggering, but they also serve as important lifelines for the humans living on their banks. From water for irrigation to water for domestic use, the Nile River tributaries are vital to North African survival of all species, including humans. It would be a human and environmental tragedy if these Nile tributaries or the great Sudd were drained and disappeared, as has Africa’s Lake Chad. Thus, these waterways deserve the respect and care owed to such treasured and vital resources.

Aswan High Dam Leaves an Environmental Legacy

November 7, 2017

by Joannah Otis for No Water No Life

This is the second our blog series on “The Nile River in Egypt” by NWNL Researcher Joannah Otis, sophomore at Georgetown University. Following her blog “Finding Hapi-ness on the Nile,” this essay addresses perhaps the greatest elements of change created thus far by humans along the Nile. [NWNL has completed documentary expeditions to the White and Blue Nile Rivers, but due to current challenges for photojournalists visiting Egypt and Sudan, NWNL is using literary and online resources to investigate the availability, quality and usage of the Nile in those regions.]

Aswan_DamAswan Dam on the Nile River in Aswan, Egypt

Background on Aswan High Dam

The Nile River snakes south to north for 4,160 miles through ten North African countries until it reaches the Mediterranean Ocean.1 Its path is interrupted only by the great Aswan High Dam, which has brought both good and bad to the Egyptian people. Towering 364 feet tall and stretching 12,565 feet along its crest, the Aswan High Dam is impressive.2 This dam was opened in 1971 after a decade of construction and seeking funds from the Soviet Union.3 Its transboundary reservoir, Lake Nasser, which backs up into Sudan for 300 miles, holds nearly two years’ worth of water from the Nile River.

Benefits of the Aswan High Dam & Lake Nasser

The High Dam, replacing a 1902 Low Dam, annually generates more than 10 billion kilowatt hours of electricity, facilitating Egypt’s path to industrialization. This new dam also marked a major shift in Egypt’s agricultural prospects. Previously, Nile River Basin farmers were forced to depend on fickle seasonal flooding, which could bring appropriate levels of water one year and often completely washed away soil the next. Such unpredictability made it hard to grow a reliable crop; and the Nile’s single flooding season precluded farmers from having more than one harvest per year.

Lake Nasser’s surplus of water has well served the irrigation needs of Egypt and Sudan, since water availability is especially critical, given Egypt’s growing population and increasing water needs. (NB:  NWNL is studying these trends that portend dire water scarcity in the near future.) The Aswan Dam now allows for two to three crop cycles annually.  Nearby aquifers are inundated by increased amounts of water due to year long, rather than seasonal irrigation.  Water levels are carefully monitored and extra water is saved for times of drought. There has been huge economic benefit to the fact that the dams has allowed Egypt to triple the output of its most important and profitable crops, wheat and cotton.5

Thus, the Aswan High Dam created a new future of irrigation water, flood control and electricity – but came with disconcerting drawbacks. Its story and continued influence on the Nile River illustrate how human ingenuity can inadvertently take a toll on the environments and ecosystems we so rely on.  The degradation of Nile ecosystems and the influx of increasing chemical runoff are reminders of the negative impacts that infrastructure, intended to improve quality of life, can have on nearby environments and habitats for all species, including humans.

Consequences of the Aswan High Dam & Lake Nasser

While Lake Nasser reservoir has allowed for controlled downstream flows into northern Egypt, that backlog of Nile water forced the relocation about 100,000 people to other lands in Sudan and Egypt.6 Abu Simbel Temple and 22 historical structures fortunately were moved under UNESCO’s watchful eye, yet Buhen Fort, the Fadrus Cemetery and other archeological sites (whose relocation would have been too costly) were submerged.

Stagnant waters in Lake Nasser have threatened the health of people using or residing near the Nile River waters. Downstream, the dam promotes the presence of schistosomiasis, a parasitic disease also known as bilharzia or “snail fever.” Schistosomiasis kills more than 200,000 Africans annually; and 20 million sufferers develop disfiguring disabilities from complications, kidney and liver diseases, and bladder cancer.

Seasonal flooding once brought thick layers of dark silt to farms, which farmers used a natural fertilizer. Unfortunately, the Aswan High Dam almost completely blocks the movement of nutrient-rich sediment downstream. (NB:  NWNL has seen similar impacts of Ethiopia’s new Gibe Dams, ending 6,000 years of flood-recession agriculture practiced by pastoralists in the Lower Omo River Basin.) As rich Upper Nile sediments collected behind the dam, Egyptian farmers resorted to toxic chemical fertilizers that drain into the Nile. These pollutants can cause liver disease and renal failure in humans.7 

Farming phosphates running into the river increase algae growth. Algae blooms, elicited by excess nutrients (eutrophication), produce cyanotoxins, which affect the health of fish and may poison humans.At the same time, fish populations no longer benefit from nutrients that used to be in upstream Nile sediments. Aquatic species in the Mediterranean Sea near the Nile Delta have suffered similarly from decreased natural nutrients and increased chemicals.9

Riverbanks also suffer from a lack of replenishing sediments as their erosion continues unchecked.  Prior to the dam’s construction, the average suspended silt load was 3,000 parts per million (ppm). Post-construction silt levels have declined to 50 ppm.10 Further downstream, the Nile Delta suffers from a lack of silt replenishment. [NB:  NWNL has documented parallel deltaic losses and damage in the U. S., as  levees along the Mississippi River withhold sediment that used to rebuild storm erosion in the Mississippi Delta.]

Silt-free water along with a lower current velocity and steady water levels have enabled invasive aquatic weeds to infest the Nile River and its irrigation canals. Large volumes of aquatic weeds, water hyacinths in particular, create stagnant water conditions, impair water flow, provide breeding grounds for malaria-carrying mosquitoes and prevent the passage of boats whose propellers become clogged with invasive weeds.  Prior to the dam’s construction, these weeds were unable to flourish due to the Nile’s varying water levels and the force of its flow.11

Erosion in the Nile Delta is especially threatening because it has led to saltwater intrusion.   (NB: Again, this is another issue also occurring in the Mississippi River Delta.)  Increased groundwater salinity from the encroaching Mediterranean Sea is decreasing cotton and rice yields.12 Additionally, fertilizers have further heightened saline levels.13

Beyond Aswan:  Footnote by NWNL Director Alison Jones

In 2009, Egypt was the most populous, agricultural and industrial country in the Nile Basin.14 The Aswan Dam has been a major factor in this march by Egypt to progress and prosperity.  However, just as the Aswan Dam came with a price – so will the upstream Grand Renaissance Dam, now under construction in Ethiopia on the Blue Nile River.  It is likely the impacts of this new Ethiopian dam – the largest ever on the African continent – will be even more consequential to Egypt than those of the Aswan High Dam.  It seems a new chapter is about to be written regarding settlement of transboundary conflicts spawned from disputes over dam impacts and upstream-downstream water rights.

Finding Hapi-ness on the Nile

October 24, 2017

By Joannah Otis for No Water No Life 

As the Nile River Basin is one of  6 NWNL case-study watersheds, NWNL has documented Ethiopia’s Blue Nile and Uganda’s White Nile.  Due however to current challenges faced by photojournalists visiting Egypt and Sudan, NWNL is using other resources to analyze the availability, quality and usage of the Nile from Khartoum north through Egypt.

This is the first in a blog series by NWNL Researcher Joannah Otis on the Nile River through Egypt, from 5000 BCE’s Ancient Egypt to today’s modern Egypt.  Joannah is a Georgetown University sophomore, focusing on Environmental Studies, Art History and Psychology.  Her home is in N.J.’s Upper Raritan River Basin, another NWNL case study watershed.   

The Ancient Egyptian pantheon of gods existed to explain the inexplicable for a people with little knowledge of the earth’s natural processes. Such faith in otherworldly figures resulted in elaborate rituals, impressive temples dedicated to specific deities, and intricate family trees. Among the most important of these gods was Hapi, also spelled Hapy, the Nile River God. Hapi’s significance in Ancient Egyptian culture indicates the vitality of the Nile River and reveals the extent of Egypt’s dependence on it.1

Since the early Nile River people never ventured far enough upstream to find the river’s true source, they turned towards their faith for an explanation of seasonal flooding and the natural flow of the nutrient-rich waters they depended upon for agriculture. It was believed that the Nile originated beneath the island Philae whose waters came from an underwater cave where Hapi resided.2  In the pyramid texts, he was said to have lived in caverns near the first cataract. As the god of fertility and fecundity, Hapi was responsible for the seasonal floods as well as the success of farms and the availability of water. As the flood waters came rushing down the Nile, Ancient Egyptians would begin presenting their offerings and sacrifices to Hapi in hopes that the flood would neither be too high nor too low. Although Hapi was worshipped throughout Egypt, he was especially revered at Aswan, today the site of a 364 foot hydro-dam, and Gebel el-Silisila, once an ancient quarry.3

In Ancient Egyptian depictions of Hapi, the god appears as a well-fed, blue or green man sporting the pharaoh’s false beard and a pair of large breasts because the Nile’s whitish waters were often associated with milk. There are no remains of temples dedicated solely to Hapi, but remnants of statues and reliefs in his likeness have been uncovered. Hapi was considered the god of both Upper and Lower Egypt, which was demonstrated by the existence of twin Hapi deities. The Hapi of Upper Egypt was known as ‘Hap-Meht’ and wore a lotus headdress while the Lower Egyptian Hapi was called ‘Hap-Reset’ and wore a papyrus headdress.

Hapi was often referred to as the ‘Lord of the Fishes and Birds of the Marshes’ and was at times worshipped over the sun god Ra.4 The Nile River God was associated with Osiris who was also linked to the Nile through his role in introducing the cultivation of wheat to the Egyptian people.5 Hapi’s wives were believed to be the cobra goddess Wadjet of Lower Egypt and the vulture goddess Nekhbet of Upper Egypt, both of whom were considered forms of Osiris’s wife Isis.6 It was Isis’s tears that were thought to replenish the Nile waters.7 Hapi’s importance in Egyptian culture and his relation to the other gods make him one of the most significant, if least well-known, gods.

THE WHITE NILE RIVER BASIN: One third of Africa’s populations reside in and depend on the natural resources of the Nile River Basin. The White Nile (2300 miles, 3700 km.) is punctuated by Lakes Victoria, Albert, Edward and Kyoga. Climate change, population growth, pollution and infrastructure are currently threatening the natural resources and balance of this watershed.

INDIVIDUAL and cooperative fishing, and water acquired via buckets and pumps, are the two traditional major uses of the Ugandan branches, tributaries and lakes in its White Nile River Basin. Today this watershed’s dramatic waterfalls challenge the adventurous rafters but are one by one being taken over to power hydro-electric dams. The No Water No Life March–April 2010 expedition to this region focused on the impacts of infrastructure projects such as these dams, limestone and oil mining, highway bridges, and Kampala hotels’ new golf courses.

NWNL documented issues including:

Forest and wetlands: The headwaters face deforestation, dam proposals and increasing settlement.

Lake Victoria: Pollution and invasive species threaten the livelihoods of 30 million lakeshore inhabitants.

Climate change: Increases in floods and droughts are greatly impacting this watershed.

White Nile River Basin Expedition – Jinga 4/10

April 10, 2010

Welcome to #10 of 11 blogs written by Alison Jones before her departure to Uganda and Kenya as NWNL’s lead photographer. Updated 4/11: Location and text have been updated to reflect revised plans.

Date: Sat–Wed, 10–14 April 2010 /Entry 10
Reporter: Alison M. Jones
Location: Jinga

NWNL will end its White Nile River Basin expedition in Jinga on Lake Victoria, the head of the Victoria Nile. With the guidance of a member of the National Association of Professional Engineers, NWNL will photograph fishing on Lake Victoria, the Bujagali and Owen Falls dams, and a local resettlement village created for those who had to be moved out of the Bujagali Reservoir. Discussions will focus on the processes followed (or not followed) in constructing these hydro dams and on other Nile River Basin projects that NAPE is focused on that impact Nile watershed ecosystems and water supplies, including oil exploration and extraction from protected areas.

From the field: The end of NWNL’s Uganda expedition was the beginning: the source of the Nile at the northern end of Lake Victoria’s Napoleon Bay! In 1862 John Hanning Speke was the first European to see Rippon Falls, submerged when the Owen Falls Dam was built (1954). At this hydrological landmark the Nile River begins its 4000-mile (6400-km), 3-month-long journey north to the Mediterranean Sea.

Our visit to Bujagali Falls, downstream from Rippon Falls, gave us an understanding of the power and drama of the Nile – what Rippon Falls was like before the Owen and Kiira Dams. Bujagali Falls provide nesting sanctuary for many bird species and are home to the spiritual gods of the Busoga Kingdom. Yet these falls will also be submerged when the government, with support of international financial institutions, finishes another large hydropower dam, despite the failed productions of the two immediately upstream.

These losses will be in vain because it is all but certain that the Bujagali dam will never reach its promised production of 250 megawatts. The upstream Owen Falls and Kiira Dams, meant to produce 350–380 megawatts of power, only produce 120 megawatts now – less than half intended! This is because of Lake Victoria’s falling water levels due to climate change, increased extraction by growing populations, and deforestation in the headwaters of rivers entering the lake. Water amounts coming into the Bujagali Dam are no different than that coming into the two upstream dams, as there are no additional tributaries between them and the Bujagali site.

Additionally, there were no proper environmental or social impact studies prior to construction. The government has largely disregarded the effects of the dam on the livelihoods of local stakeholders, whether resettled or suffering from the blast impacts. Surrounding communities (comprising over 8000 people) are struggling with landlessness, food insecurity, declining environmental quality, declining health, collapse of their fishing industry, and uncertain socio-economic futures. Resettled farmers who were moved from the Nile’s riverine flood plains have been struggling for 10 years to live on reassigned land that lacks water, sanitation or trees.

On top of these socio-economic issues, the cost of the dam relative to the amount of power expected will make Bujagali Dam’s hydropower the most expensive in the world – certainly not affordable to the 90% of Ugandans who currently lack electricity. NWNL hopes that the advocacy efforts of its newest partner, NAPE (National Association of Professional Issues), will help raise awareness and mitigate some of the problems being caused by the Bujagali Dam. The World Bank and the European Investment Banks are currently conducting investigations and withholding their critical funding until the reviews are concluded and recommendations initiated.
