How was the Aswan high dam had an adverse effect on human health? It created new ecosystems in which diseases such as malaria flourished. An environmental challenge facing the Great Man Made River is that pumping water near the coast. May contaminate aquifers with salt water from the sea.
What are the positive effects of the construction of the Aswan High Dam in Egypt?
The collective benefits of Aswan High Dam (AHD) are increasing the Egyptian water resource, controlling and regulating floods, protecting Egypt from potential frequent droughts, increasing agriculture productivity, and completely regulating the river water.
What is the major problem with the Aswan High Dam?
Despite its successes, the Aswan High Dam has produced several negative side effects. Most costly is the gradual decrease in the fertility of agricultural lands in the Nile delta, which used to benefit from the millions of tons of silt deposited annually by the Nile floods.
How does the Aswan create environmental problems?
The Aswan High Dam, when it was build created Lake Nasser, Lake Nasser Streches back 270 kilometres from the Dam. The Lake has also created alot more land for people to farm on. This is because a lot of water is stored in the lake, and in turn this water can be used to irrigate land around Lake Nasser.

What are the positives and negatives of the Aswan High Dam?
(Controls flooding) Easier to navigate river because of consistent, controlled flow. Hydro-electric power (Electricity from a clean source.) Better fishing from the lake that was created from the dam. (Lake Nasser) Cons No more silt replenishment.
How did the Aswan Dam affect the environment?
The Aswan High Dam brought the Nile’s devastating floods to an end, reclaimed more than 100,000 acres of desert land for cultivation, and made additional crops possible on some 800,000 other acres.
What have been negative effects of the dam?
Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.
Why was the Aswan Dam a disaster?
It was built nearly 5,000 years ago. And it was a spectacular failure: archaeologists believe the dam burst almost immediately. One cannot fault the ancient Egyptians for trying. Water was scarce, and rainfall uneven.
How did the Aswan Dam affect electricity generation in Egypt?
The dam also improved navigation across the Nile, benefiting the tourism and fishing industries. Water from the dam is used to feed 12 power turbines, which provides half of Egypt’s power demands. The reservoir also helps supply water during droughts.
How has the Aswan High Dam hurt Egypt?
The negative effects include increasing soil salinity, changes in the water table, excessive downstream water plant growth, and diseases such as schistosomiasis and other intestinal parasites, and the social impact on the Nubians, whose homeland was flooded.
What would happen if the Aswan Dam burst?
What if the dam were destroyed, leaving Lake Nasser to rush downstream? The answer is that a tidal wave of such magnitude would be created that Egypt would essentially cease to exist as a country. Tens of millions of people would be killed, and untold material damage would be created.
What problem did the construction of the Aswan High Dam create for the people of Egypt and their environment?
Recall from the Theroux reading (National Geographic) that schistosomiasis has been present in the region for thousands of years, but the reservoir is a huge breeding ground.In some areas, the building of the Aswan dam caused an increased occurrence of schistosomiasis among the population — from 21% to almost 100%.

What are the effects of the construction of the Dangar dam?
After the building of the dam, a noticeable decline in the production of fish in the area was marked. The usual supply of food and nutrients for the sea animals have been trapped and produced lesser compared before. Also, the absence of the flooding in some areas has led to the disappearance of minerals normally used as fertilizers.
