Improve on-farm irrigation management

  1. 1. Improve on-farm irrigation management Atef Swelam, ICARDA On-farm irrigation management a.swelam@cgiar.org
  2. 2. The available annual water per capita is about 600 m3 Egypt Population is about 95 million 95% of Egypt land is desert Renewable water resources is 55.5 billion m3
  3. 3.  land fragmentation  lack of appropriate good agricultural practices (GAP) at the field level  adoption of new AWM practices is very low (farmers attitude)  inequitable water distribution along meskas and marwas  inefficient and outdated extension systems and advisory services  low-level adoption of new and good practices  lack of incentives in Ag. sector from the states (mostly seniors who are farming now, juniors are away)  drop in water quantity and quality  poor management of water, land and fertilizers  lack of follow-up by the community after new agricultural activities or interventions have been introduced The challenges

  14. 14. Central Objective: To sustainably improve the livelihoods of resource-poor rural communities in Egypt by introducing open-source solutions for enhanced water productivity. Improve the productivity of small-scale farming systems through more effective and efficient use of water and land resources. 1 Improve farm profitability by scaling out improved irrigation and agricultural practices. Immediateobjectives 2 Develop and disseminate innovative and cost- effective integrated packages at the field level to increase agricultural water productivity 3 Improve on-farm irrigation management
  15. 15. Management of Saline Soils to Improve Productivity
  16. 16. Low quality irrigation water (mixed) Poor soil structurer Rapid salinity build up
  17. 17. Salinity in Irrigated Areas is Unavoidable……… ………Unless irrigation and salts are well managed
  18. 18. Subsoiling Gypsum application Gypsum is a good option to improve the soil salinity by replacing sodium with calcium
  19. 19. Maintenance and operation of open field drains It is important to maintain the open field drains to be capable to convey drainage water out of the fields to improve soil conditions.
  20. 20. Mole drain practice to improve drainage efficiency and improve soil quality

  22. 22. FP MRB Mechanized raisedbed practice to improve soil salinity
  23. 23. Fertilizer management under saline water irrigation Fertilizer management under conjunctive use of saline water  Nitrogen +20% than the conventional rate resulted in better crop establishment  Increase in cotton yield up to 16%
  24. 24. Mulching of alternate furrows and irrigation with saline water on a salt-affected soil  Decrease ET by 12%  Increase is cotton yields by 10%  Increase in WP by 14%  Reduction in soil salinity by 18% Mulching practice
  25. 25. Sustainable interventions to address degradation associated with salt-affected soils Packages introduced include: application of gypsum, organic matter, bio-fertilizers, ammonia injection, mole drains and laser leveling. Application of gypsum combined with ammonia gas and farm manure helped to: • improve soil physical and chemical properties, and subsequently improved soil structure and hydraulic conductivity • increase the crop yield by 20-30% • reduce soil salinity by 35% • Improve water productivity by 50% • Increase farm income by 15% The introduced package is being implemented/partially by 20% of the young farmers in the northern Delta
  26. 26. 1. Improve the estimation of ETc and Kc for farmers and water agencies 2. Validating the crop ET using Energy Balance 3. Develop ET maps for different agro-climatic zones 4. Upgrade crop coefficient (Kc) values to improve: • On-farm irrigation management • Confidence in the Kc values • Water demand estimates for regional planning Objectives: Water Demand Management
  27. 27. ET = Rn - G - H Rn (radiation from sun) Heat to air Transpiration heat to Ground The energy balance includes all major sources (Rn) and consumers (ET, G, H) Evaporation • The Surface Renewal (SR) and Eddy Covariance (EC) methods provide a good alternative to using expensive lysimeters to measuring ETa. • The SR method is the least expensive and it requires less fetch, so it is useful for small plantations. • The SR method is useful for upgrading the crop coefficients to improve on- farm irrigation management, confidence in the Kc values and water demand estimates for regional water planning The technology

  44. 44. Central Objective: To sustainably improve the livelihoods of resource-poor rural communities in Minya and Fayoum governorates in Egypt by introducing open-source solutions for enhanced water productivity. Improve the productivity of small-scale farming systems through more effective and efficient use of water and land resources. 1 Improve farm profitability by scaling out improved irrigation and agricultural practices. Immediateobjectives 2 Develop and disseminate innovative and cost- effective integrated packages at the field level to increase agricultural water productivity 3
  45. 45. Expected Outcomes  Marwas in pilot areas Minya and Fayoum are improved  Farmers in Minya and Fayoum adopt more efficient and integrated on-farm irrigation and agricultural packages.  Guidelines on improving water productivity and farm income are produced; the guidelines are then disseminated to communities in the two areas.  Stakeholders gain improved awareness regarding good agricultural practices.  Improved irrigation practices are fine-tuned, calibrated, and tested under farm conditions; they are then disseminated to farmers.  Information/knowledge on potential benefits and trade-offs using various technologies are synthesized and shared with stakeholders.  Crop water productivity maps for Minya and Fayoum are produced and disseminated.  Reports on options and guidelines of promising technologies that improve water-land-crop productivity are developed and shared with relevant stakeholders. The project will use proven science-based on-farm applied research. The outputs and outcomes will enhance productivity and sustainability of agriculture. The project will create synergies with other ongoing EU-JRDP activities in the same areas of intervention of Bahr Awlad Mohamed and Bahr Biahmu in Fayoum and Hafez Al Sharkyia in Minya.
  46. 46. Project Interventions  Promote farmers’ awareness on the adoption of good irrigation practices and improve the conventional practices for enhanced irrigation efficiency.  Support farmer water user associations (WUAs) by reinforcing existing organizations or creating new ones with special attention to gender sensitivity.  Rehabilitate the marwas for adequate and more efficient delivery of irrigation water to farmer field.  Conduct proper land levelling for pilot areas and facilitate the maintenance of open field drainage networks.  Facilitate the improvement of soil quality (gypsum application)  Introduce and train farmers on using the mechanized raisedbed technology for precision water and agricultural operations.  Strengthen the role of collective action by building the capacity of growers, WUAs, water planners and decision makers to improve sustainable productivity in all dimensions (social, economic, and biophysical). Facilitate the dissemination of good irrigation techniques and practices.  Promote the concept of community-based, participatory approach of irrigation improvement by involving stakeholders in the entire implementation process.  Conduct inception and validation workshops to disseminate the project’s key findings. Through a participatory approach, the project will support the target groups with innovative packages to improve on-farm irrigation management. The interventions will include
