  1. Framework of the study • Problem definition • Objectives of the study • Background of studied area • Methodology • Results and discussion • Conclusions and recommendations

  2. Problem Definition • The agricultural sector employs more than 55% of labors force . • Rain, spate and spring irrigation were predominant in the past in Sana’a Basin. • Since thirty years ago tub-wells became the main source for water irrigation. • Agriculture consumed approximately 90 % of groundwater for irrigation by using traditional irrigation methods

  3. Groundwater depletion is About 5-7m per year • Estimated Withdrawal is ≈ 260Mm3 • Recharge of groundwater is about 46Mm3 • Quality of water degradation • So agriculture activities will face a big problem in the near future

  4. Study Objectives • To discernment irrigation water management on-field level. • To evaluate the role of economic incentives in groundwater depletion. • To assess farmers awareness, policy and the application of legislation to improve irrigating water uses efficiency.

  11. Previous Studies Sana'a basin submitted to many studies but the important of them is: • Italconsult between 1970-1973 • Howard hammvi, 1980-1983 • Russian study by Mosgiprovodkhoz, 1986 • TNO, 1987-1996 • WEC studies in 2001. • Hydrosult, SBWMP, 2003 ( continues) • GAF, 2005 • JICA studies in 2007

  31. Type of irrigation

  32. Irrigation method

  33. Estimated distance between the farm and source of irrigation water

  34. Economic Incentives

  36. Do you get more yield If you add more water for crops?

  37. Are you using modern irrigation technologies?

  38. Reasons which delay using modern irrigation methods

  39. Problems accompanying using modern irrigation methods • Blockage • Design difficulties • Unsuitable for big tree • Expensive • Bad quality • Lack of instructions • Tilling • Scattering of frame parts • Low yield • Change crops • Long distance between farm and well

  40. Crops need more water irrigation

  41. Are you cultivated crops need more water?

  42. Social Awareness

  43. Are your region suffer from water lack?

  44. Rationing water used by using modern irrigation Methods • Guidance farmers to use modern irrigation Methods, non expended in area of cultivation and no flooding • Water saving • Awareness and advice • Subsidies and entering modern irrigation Methods Goals of WUA
