Water Issues Along Egypt’s Nile River

By Joannah Otis for No Water No Life

This is the 8th blog in our series on the Nile River in Egypt by NWNL Researcher Joannah Otis, sophomore at Georgetown University. This essay addresses some of today’s most pressing water issues in the Nile River Basin. [NWNL expeditions have covered the Upper Nile, but due to current challenges for US photojournalists in Egypt and Sudan, NWNL is using literary and online resources to investigate the Lower Nile.]

Over the past few years, water shortages, river pollution and saltwater intrusion have increasingly plagued Egypt. These issues are exacerbated by a population that’s grown by 41% since the early 1990’s.  In the next 50 years, the population is expected to double, yet Egypt has a very limited water supply. Egypt receives only 80 millimeters of rain per year, and so the Nile River provides 97% of its freshwater. This increasingly industrialized nation also faces a profusion of pollution in the Nile River coming from chemical runoff and industrial waste.1 As well, the Nile River Delta is experiencing saltwater intrusion due to its sinking northern corners.2 These three issues – among others – demand changes if Egypt and its Nile River are to continue to be healthy, functioning entities.

With one of the world’s lowest per capita water shares, Egypt barely meets its water needs today – and yet it also needs to prepare for millions of additional people in coming years. Only 6% of Egypt is arable agricultural land, with the rest being desert.  Inefficient water irrigation, uneven water distribution, and misuse of water resources have all contributed to Egypt’s current dire situation.The country faces a yearly water deficit of about 7 billion cubic meters. Its water comes from nonrenewable aquifers, meaning they cannot be recharged or reused once they are dry.

Despite these pressures, many farmers use an unproportionate amount of water by continuing to employ outdated and inefficient irrigation techniques. One of these is “basin irrigation,” where entire fields are flooded with water that evaporates or is later drained off. Ancient Egyptians used the same practice to water their crops, but then the population was much lower and as a result, water was more plentiful. The approximately 18,000 miles of canals supplying today’s farmers also contribute to water waste, because evaporation in the canals absorbs about 3 billion cubic meters of Nile River water per year.4

Water pollution is particularly significant in the Nile River Delta where factories and industrial plants have sprung up. These companies often drain dangerous chemicals and hazardous materials into the river, causing fish and other aquatic wildlife to suffer. A large number of fish deaths, due to high levels of lead and ammonia, has been reported. Bacteria and metals in the water are particularly harmful. The agriculture sector also contributes to water pollution via pesticide and herbicide runoff.5 This toxic combination of pollutants has been known to cause liver disease and renal failure in humans.6

Saltwater intrusion is another large concern for the Nile River Delta, which is slowly sinking at a rate of 8 millimeters per year. This is an alarming amount since the Mediterranean Sea is rising about 3 millimeters per year and the Delta plain is only one meter above sea level. Although only the northern third of the delta is affected, saltwater intrusion could spell disaster for area crops if they do not adapt to soil with a high salinity.7  Further crop threats come from the lack of silt filtering downriver. This silt once provided enough nutrients to the fields that farmers did not have to apply synthetic fertilizers. With the construction of the Aswan High Dam, however, silt was blocked upstream and the Nile Delta suffers as a result.8

The Nile River Basin is facing a plethora of largely human-driven issues from pollution to water overuse. In order to preserve the Nile River and its people, various steps are needed to protect its environs. Solutions include passing legislation to prevent industries from dumping hazardous waste, building more sewage treatment plants, and transferring silt downstream as natural fertilizer. Action is needed to save Egypt’s famous Nile, and it needs to be done with haste.

Is the California Drought here to stay?

The short answer is an emphatic, “YES!” It is real. Even if El Niño arrives next year, as some climatologists have hinted, California currently uses too much water to allow replenishment of its reservoirs and ground water – now at historic low levels. It is predicted that precipitation levels will fluctuate wildly, as they have historically, while water demand increases. The California Data Exchange Center reports that California reservoirs are at 62.39% of average. Some are as low as 7 and 9%. The Sierra snowpack in the northern part of the state has reached 21% of average, up from 12% before the early March storms. Nowhere in the state is the snowpack above 34% and very little rain is forecast for the rest of this year’s rainy season. San Francisco residents depend on snow melt for their water. Some towns in California are predicted to have no water within 60 days. Irresponsible water use should not drain our precious resource.

One answer is conservation and planning. According to Barton H. “Buzz” Thompson, an expert in environmental and natural resources law and policy at Stanford University, there are many ways that Californians can use less water. At a symposium presented by the Bill Lane Center for the American West and the Water in the West Project at Stanford University, Thompson proposed that the state protect ground water, protect the environment, avoid building new reservoirs and desalinization plants, set up water exchanges where even fish have water rights, and encourage water utilities to tier water rates.

Many of us who were here in the big droughts of 1976-77 and 1985-86 have already tightened our belts, so trying to reach the voluntary 20% reduction, as requested by Governor Brown, is going to mean even more careful planning. California has more people and less water. The state produces nearly half of US-grown fruits, nuts and vegetables and has the highest per-state cash farm receipts in the nation, per CA Dept of Food and Agriculture. This farmland has international importance as well. It grows 70% of the world’s almonds.

The state needs to put serious water conservation measures in place before any rains that El Nino might bring next year could lull everyone back into complacency.
