The air pollution in Cairo is a matter of serious concern. The air pollution in downtown Cairo is more than 10 to 100 times of acceptable world standards. [8] Cairo has a poor factor because of lack of rain and its layout of tall buildings and narrow streets, which create a bowl effect (bad ventilation and consequent trapping of pollutants).
Water resources management in Egypt depends on a complex set of infrastructure along the entire length of the river. The key element of this infrastructure is the Aswan High Dam that forms Lake Nasser. The High Dam protects Egypt from floods, stores water for year-round irrigation and produces hydropower.
During autumn, parts of the Nile River are red with lotus flowers. The Lower Nile (North) and the Upper Nile (South) have plants that grow in abundance. The Upper Nile plant is the Egyptian lotus, and the Lower Nile plant is the Papyrus Sedge (Cyperus papyrus), although it is not nearly as plentiful as it once was, and is becoming quite rare. [20]
Along the river upstream, the banks support dense growths of reeds (genus Phragmites) and bulrushes (genus Typha). The Nile in Egypt has 533 species of plants, eight of which are endemic. [4] The delta and riverine wetlands of the ecoregion are an important stopping point for migratory birds on the Asian–East African Flyway.
The Nile river is the only water source for most of Egypt, including its capital Cairo shown here. Egypt's main source of freshwater is the Nile River. The river supplies 55 billion m 3 of freshwater every year, which represents 97% of all renewable water resources in Egypt. [5] Overall, the Nile River constitutes about 90% Egypt's water supply.
reduced discharge into the sea, which may have various consequences like coastal erosion (e.g. in Ghana [7]) and saltwater intrusion in delta's and estuaries (e.g. in Egypt, see Aswan dam). Current water withdrawal from the river Nile for irrigation is so high that, despite its size, the river does not reach the sea in dry periods. [6]
Water pollution from factories and industry is typically federally regulated. The Biden administration recently proposed toughening regulations on meat and poultry processing plants to reduce ...
At that time, the motifs of importance are those based on the lotus and papyrus plants respectively, and these, with the palm tree capital, were the chief types employed by the Egyptians, until under the Ptolemies in the 3rd to 1st centuries BC, various other river plants were also employed, and the conventional lotus capital went through ...
