To the west of Nile Valley, eastern Sahara was the home of several
Neolithic cultures. During the
African humid period, this was the area with rich vegetation, and the human population in the Sahara had increased considerably by about 8000 years BC. They lived by hunting and fishing in the local lakes, and by gathering wild
cereals of the Sahara, that were abundant. The cereals such as
brachiaria,
sorghum and
urochloa were an important source of food. The African humid period was gradually coming to an end, and by about 6,000–5,000 years ago it was over. Well before that time, the migrating herders were going to other parts of Africa, but also coming to the Nile delta, where there were relatively few indications of agriculture before that.
Dakhleh Oasis, in particular, has been the subject of considerable recent research, and it supplies important evidence for early Egyptian agriculture. It could be considered typical of post-Pleistocene developments in Northeastern Africa in general. Dakhleh Oasis is located in
Western Desert (Egypt). It lies 350 km (220 mi.) from the
Nile between the oases of
Farafra and
Kharga. In Dakhleh, the Bashendi culture people were mobile herder-foragers during the African humid period. They lived in slab-built settlement sites, and open-air sites consisting of clusters of hearth mounds. Elsewhere in the Western Desert of Egypt, Bashendi-like groups have also inhabited the
Farafra Oasis, and
Nabta Playa, to the south. At Farafra Oasis, a goat dated around 6100 BC (8100 cal BP) was found in the Hidden Valley village. At Nabta Playa, remains of sheep/goat and cattle are present beginning about 6000 BC (8000 cal BP). Yet goats and cattle are almost the only Neolithic elements from the Near East that the oasis dwellers accepted. Other cultural developments, such as the lithic industry, originated locally, or at least from within Northeastern Africa. As for crops,
emmer wheat and
barley are found in the Faiyum at the sites of Kom K and Kom W, dated ca. 4500-4200 BC. Merimde culture overlapped in time with the
Faiyum A culture, and with the
Badari culture in Upper Egypt, which are dated somewhat later. These were all agricultural cultures Farming systems.
Nile and field planting The civilization of ancient Egypt developed in the arid climate of northern Africa. This region is distinguished by the Arabian and Libyan deserts, and the
Nile. The Nile is the longest river in the world, flowing northward from
Lake Victoria and eventually emptying into the Mediterranean Sea. The Nile has two main tributaries: the
Blue Nile which originates in Ethiopia, and the
White Nile that flows from Uganda. While the White Nile is considered to be longer and easier to traverse, the Blue Nile actually carries about two-thirds of the water volume of the river. The names of the tributaries derive from the color of the water that they carry. The tributaries come together in
Khartoum and branches again when it reaches Egypt, forming the Nile delta. The Egyptians took advantage of the natural cyclical flooding pattern of the Nile. Because this flooding happened fairly predictably, the Egyptians were able to develop their agricultural practices around it. The water levels of the river would rise in August and September, leaving the floodplain and delta submerged by 1.5 meters of water at the peak of the flooding. This yearly flooding of the river is known as inundation. As the floodwaters receded in October, farmers were left with well-watered and fertile soil in which to plant their crops. The soil left behind by the flooding is known as silt and was brought from Ethiopian Highlands by the Nile. Planting took place in October once the flooding was over, and crops were left to grow with minimal care until they ripened between the months of March and May. While the flooding of the Nile was much more predictable and calm than other rivers, such as the Tigris and Euphrates, it was not always perfect. High floodwaters were destructive and could destroy canals that were made for irrigation. Lack of flooding created a potentially greater issue because it left Egyptians suffering from famine.
Irrigation systems To make the best use of the waters of the Nile river, the Egyptians developed systems of irrigation. Irrigation allowed the Egyptians to use the Nile's waters for a variety of purposes. Notably, irrigation granted them greater control over their agricultural practices. The perennial irrigation required by gardens forced growers to manually carry water from either a well or the Nile to water their garden crops. Additionally, while the Nile brought silt which naturally fertilized the valley, gardens had to be fertilized by pigeon manure. These gardens and orchards were generally used to grow vegetables, vines and fruit trees. ==Crops grown==
