The by gravity irrigation in the Gezira and Almanagil scheme from the Sennar Dam down to the minor canals is suitable and cost-effective because of the natural slope from south to north and the current infrastructures. However, the situation of the on-farm water distribution in each production unit (Nimra) of 90 feddan is severely defective. There are 18 sections (administrative units) in the Gezira and Almanagil scheme (2.2 Million acres) farmed by 144,000 farmers. This proposal is to establish an expanded pilot project to introduce Rigid Gated-Pipe (RGP) irrigation to replace the inefficient, laborious outdated short-furrow-basin method (Angaya). Rigid gated-pipe irrigation is a proven technology commonly used in the USA in small- and large-scale farms. The project will train 180 farmers to: 1) install water delivery gates (DamGate®) in irrigation PVC pipes, 2) learn to use RGP to manage water delivery in their farms and 3) schedule irrigation for optimum crop establishment and increased yield. The on-farm training will be used to set-up RGP demonstration in a Nimra inn each of the 18 sections of the Scheme. Future adoption of RGP irrigation will lead to 20% increase in furrow irrigation efficiency, conserve irrigation water by approximately 20 to 30%, reduce famers exposure to health hazards in water ditches, 20% yield increase and lead to decent work conditions and higher income of 144 thousand farmers and their families.
Rationale and current situation:
The current on-farm water delivery and distribution method known as Angaya i.e. irrigating short furrows of 20 meter-long in 14 basins in each feddan was adopted for irrigation about 90 years ago. This method is inefficient, laborious, difficult to deliver optimum crop water requirement, major cause of crop water logging, inadequate crop establishment, and hence low crop yield. Additionally, the farmland (Hawasha) has totally transformed to uneven unmanageable surfaces for irrigation due to Angaya system. On the other hand, the open ditches (tertiary canals) are sources of health hazards and diseases such as malaria and schistosomiasis. The current water distribution cause social tensions between farmers, frustration and led to abandoning farming altogether. Today’s farmers (in the 21st century) are eager to adopt new technologies and deserve to be trained to use modern farming technologies. The current situation of the irrigation system in Gezira is affected by many factors including sedimentation and noxious weed infestation at the lower levels of canalization. The irrigation network in Gezira is damaged because of many factors including outdated and collapsed infrastructures and lack of appropriate farming policies. Modernization of irrigation system in Gezira scheme is over-due.
Implementation and methodology
Expected deliverables and impact
Expected yield increase:
To estimate the yield increase due to adopting RGP, there is need to conduct a cost-benefit analysis of two seasons data from comparison of the current method with the RGP. In general, based on the above information including added 15% farmland, the expected yield increase could be at least 20 to 25% in addition to improving the overall farming and working conditions, health of farmers and water conservation.
It is imperative to train a sample of farmers (10) in all sections of the 18 sections. The training can be achieved in 3 days scheduled as follows:
Each class will consist of 20 farmers 1 days in-class lessons and 2 days field work. The training topics include:

Measurable Outcomes (Goals)
1. Increases farmland use by at least 15%, as it eliminates all open ditches (Abu XX and Abu VI).
2. Reduces irrigation water use by approx. 30% as water is directed to a single furrow. It reduces evaporation from all open ditches, seepage, weeds, run-off waters and over watering.
3. Increases furrow irrigation efficiency by approx. 20%.
4. Reduces energy (fuel or electricity) used to pump water by 30% in case of pumped water.
5. Improves crop stand (emergence) because it is easier to prevent over watering of seedlings.
6. Reduces overall weeds infestation, as weeds in open ditches are major source of weed seed.
7. Increases crop growth uniformity that reduce weed competition.
8. Provide decent work conditions and reduce exposure to water born diseases and chemicals
