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.

The Importance of New Irrigation Technologies

Agriculture has a serious duty of care. Where possible, it needs to move away from flood irrigation, which despite the water wastage it involves, is still the most-used irrigation technique worldwide.

Drip Irrigation to the Rescue

One of the biggest technological breakthroughs in irrigation science in the 20 th century was the development of drip irrigation. It has the ability to deliver water to the root systems of crops and thereby reduce the amount of water needed for irrigation by as much as 70%.

Why is irrigation important?

The importance of irrigation can be explained in the following points: Insufficient and uncertain rainfall adversely affects agriculture. Droughts and famines are caused due to low rainfall. Irrigation helps to increase productivity even in low rainfall.

How does irrigation help farmers?

Irrigation has stabilized the output and yield levels. Irrigation increases the availability of water supply, which in turn increases the income of the farmers.

What are the two methods of irrigation?

Two different methods of irrigation are- modern methods that include sprinkler irrigation and drip irrigation ; traditional irrigation that includes manual irrigation where water is pulled out by the farmers themselves from the wells and canals to irrigate the land.

What is irrigation in agriculture?

What is Irrigation? Irrigation is the process of applying water to the crops artificially to fulfil their water requirements. Nutrients may also be provided to the crops through irrigation. The various sources of water for irrigation are wells, ponds, lakes, canals, tube-wells and even dams. Irrigation offers moisture required for growth …

What is a sprinkler system?

Sprinkler System. A sprinkler system, as its name suggests, sprinkles water over the crop and helps in an even distribution of water. This method is much advisable in areas facing water scarcity. Here a pump is connected to pipes which generate pressure and water is sprinkled through nozzles of pipes.

What is the process of supplying water to the land at regular intervals?

Irrigation is the process of supplying water to the land at regular intervals by means of canals and other artificial methods, to enhance agricultural growth and maintain the landscape during the periods of less average rainfall.

Why is irrigated land important?

The main reasons for irrigation are: 1. Not enough rainfall to support crop growth.

What are the two main types of irrigation systems?

There are two main types of agricultural irrigation – gravity powered and pressure driven systems . Gravity powered systems are, as the name implies, driven by gravity. Pressure driven systems require an electrical pump in order to provide the irrigation system with water. Examples of gravity powered systems include:

Why is there not enough rainfall to support crop growth?

Not enough rainfall to support crop growth. This may be due to rainy and dry seasons, drought or arid/semi-arid climate conditions. Irrigation systems may also be used to maintain consistent moisture levels even in areas with moderate precipitation levels as it has been shown to improve crop performance. 2.

Why is soil salinity high?

High soil salinity levels can be a natural occurrence which is the case in many semi-arid and arid locations or a result of poor agricultural practices and ineffective drainage. In cases impacted by salt levels in the soil, irrigation must often be coupled with drainage in order to achieve the desired benefits.

What is irrigation in agriculture?

Most people think that irrigation is all about watering the crops, and this is certainly the primary function. They’re either watered overhead, or via the soil, and this form of reticulation uses only the necessary amount of water for environmental reasons.

What is irrigation used for?

In some areas, irrigation is used to help with weed control, especially in rice and other grain fields. This is mostly when managing aquatic weeds, although a system called buried drip irrigation can be used, where drip tape deprives the weeds of water, while keeping plants hydrated.

What is surface irrigation?

When most people think of irrigation, they’re talking about surface irrigation, where sprinklers move across the surface of the land, wetting the soil. This allows for crops to be watered easily, and means farmers don’t have to worry about lack of rain.

Where are sprinklers used?

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.
