Early Irrigation in Egypt

The River Nile flooded its banks for several months each year. The Egyptians diverted the floodwaters to nearby fields to enable farmers to grow crops that, without the presence of life-giving water, would otherwise have been impossible.


Early Irrigation in Mesopotamia

Meanwhile, in Mesopotamia, the floodwaters of the Tigris and Euphrates rivers were used in a similar way. In fact, it was the Sumerians who are credited with the first irrigation engineering works in history when they built a series of canals which it is now thought could have been used for 1000 years before they needed replacing.


The Sumerians

The Sumerians, who inhabited Sumer, humankind’s first big civilisation, were great innovators, and in their efforts to transform the desert into an oasis, they invented what is thought to be the world’s first plough which appeared around 3500 BC.


The Depletion of Underground Water

Water is a limited resource, with agriculture requiring approximately 70% of global water. It will be critically important to develop new technologies to help us manage, regulate and optimise the best use of water as underground reserves are slowly being depleted.

Sprinklers are a type of irrigation often used in people’s back yards, but they’re also useful in agriculture. Sprinklers can be placed at set points, and programmed to water efficiently, or you may see travelling sprinklers which move around different points of the farm.


How does water help agriculture?

Water for agriculture is increasingly recognized as a major constraint to improving the lives of the rural poor and is an important component of rural livelihood programs that need to be yet strongly established in Ethiopia. Irrigation has contributed significantly to poverty reduction, food security, and improving the quality of life for rural populations. The majority of existing traditional and modern irrigation schemes are micro level in size. Most of these schemes are used stream, river and lake diversions but some may be dependent on small dams and perennial springs which show ground water potential for irrigation did not get emphasis. Fogera is one of Blue Nile basin area in Ethiopia and known by flooded plain. The woreda has high ground water potential. Now a day there is irrigation practice in the area for production of vegetables, horticulture (onion, tomato and purple) and in some extent maize. Even if there is such practice in the area, beside high ground water potential almost all farmers are used two perennial rivers called Rib and Gumara as a water source for their irrigation crop production using motorized pump. But the beneficiary farmers are those having farm land near or around streams, while those farmers bounded with these rivers and have not farm land around the stream waiting until the rainy season to cultivate crops.


What is the purpose of ground water in the Fogera Plain?

In the Fogera plain groundwater is important source that can be used for irrigation crops year around. Reducing dependency on rainfall and stream water for crop production little has known about the potential use of ground water in the area. Rain fed agriculture alone cannot be insuring food self-sufficiency for the country having uneven distribution and erratic rainfall. Rather in addition to rain fed, implementing irrigation schemes according to water source potential weather surface or ground water is important. For those areas having high ground water potential, ground water may serve as a water source for irrigation crop production and increase income. But to use this precious natural resource actively and efficiently tackling obstacles related to ground water use for irrigation crop production is the primary task. This paper will investigate constraints in the Fogera Woreda on ground water uses for irrigation crop production.
