2 TANZANIA WATER BASINS

3 DISTIRIBUTION OF IRRIGATION POTENTIALS

4 High potential: 2.3 million ha Medium potential: 4.8 million ha Low potential : 22.3 million ha Total 29.4 million ha

5 KILIMANJARO ZONAL IRRIGATION AND TECHNICAL SERVICES UNIT (KZITSU) The KZITSU covers the three regions: –Tanga - 26,809 sq.km; –Kilimanjaro - 13,309 sq.km; –Arusha - 36,486 sq.km.

6 Total irrigation potential is approximately 219,542 ha whereas total area under irrigation is estimated at over 96,513 ha as follows: Tanga region: 8,676 ha Kilimanjaro region: 45,767 ha Arusha region: 42,070 ha 96,513 ha

7 According National Irrigation Master Plan(2002), there are four (4) types of small-holder irrigation schemes existing in Kilimanjaro Irrigation Zone: According National Irrigation Master Plan(2002), there are four (4) types of small-holder irrigation schemes existing in Kilimanjaro Irrigation Zone: Traditional irrigation schemes………. 630 Traditional irrigation schemes………. 630 Water harvesting schemes Water harvesting schemes (Spate Irrigation) …………..…………....6 Modern irrigation schemes……………..26 Improved traditional irrigation (Spate Irrigation) …………..…………....6 Modern irrigation schemes……………..26 Improved traditional irrigation Schemes………………………………...42 Schemes………………………………...42 TOTAL 704 TOTAL 704

10 Role of the Zonal Irrigation and Technical Services Units: –Assist districts in identification of potential areas for irrigation development; –Conduct topographical surveys or supervise survey work whenever implemented by private surveyors; –Assist districts to develop plans and designs of irrigation schemes and prepare tender documents for District Tender Boards; –Assist districts in the process of tendering of works and procurement of facilities; –Assist districts in supervision of contracts;

11 –Conduct awareness seminars to district staff and facilitate district teams to organize awareness seminars and workshops to farmers; –Assist in the arrangement of training for various stakeholders; –Assist in the commissioning of completed irrigation schemes; –Selection of dam sites and design dams for construction; –Assist districts in monitoring production in completed irrigation schemes; –Assist districts in the preparation of sub- component budgets; and –Preparation and submission to BTC of compiled sub-component budget, quarterly and annual Reports.

12 Some important activities in hand 1.0 Rehabilitation of Makeresho Irrigation Scheme (2009/10….. ) 2.0 Rehabilitation of Mandaka Mnono Irrigation Scheme (2009/10….. ) 3.0 Kivulini Irrigation Scheme (2009/10….. ) 4.0 Mbuganyekundu Irrigation scheme (2009/10…..)

29 DIVERSIFICATION OF SPATE IRRIGATION Use of harvested crop leftover for livestock feeding

30 Stock piling maize leftover after harvest storing for future consumption

31 Truck carrying maize leftover for stockpiling

32 Stockpiling maize leftover for livestock consumption during dry season

33 Hays of beans leftover for livestock which are said to have high nutrients

34 Naming’ongo Irrigation scheme one of typical Spate Irrigation scheme

35 Sketch of headwork design

36 Newly completed headwork with a bridge Trash Rack Semi Automatic Flood Flushing gates

37 Tree logs in front of upstream apron after flooding

38 Downstream of headworks the part with semi-automatic Flood Flushing gates Semi-Automatic Flood flushing gates

39 Downstream of headwork/bridge Solid wear part Semi-automatic Flood Flushing gates

40 Chain saw cutting logs of trees Cut down tree logs using chain saw

41 Beneficiaries cutting down the tree logs using chain saw Cut down tree logs using chain saw

42 OTHER IMPORTANT ASPECT OF SPATE IRRIGATION especially improvement of Post Harvest Losses which is estimated to be 40%

43 Traditional wooden stick storage facility Inlet /outlet

44 Storage facility made of soil bricks with capacity 1000 kgs Inlet Outlet with a pad lock

45 Storage facility made of burnt bricks with capacity 2,000 kgs Outlet with a pad lock Inlet

46 Storage facility made of cement paste with capacity 1000 kgs inlet Outlet with a pad lock

47 Improved grain storage tanks with capacity of 50 tons Outlet with a pad lock Inlet

48 Other coupled activities with regard to Spate Irrigation and adaption to climate change a) Water saving technologies b) Environmental protection by minimizing use of firewood in (1) Improved cooking stoves (2) Use of Rice husks to burn bricks

49 a) Rainwater harvesting tank from roofs with capacity of 16,000 lts Outlet with a pad lock Inlet pipe from roof gutters

51 Drip irrigation family Kit 200 lt water storage tank Filter Laterals

52 Drip irrigation at agricultural show Laterals

53 Agricultural Farmers show on every 8 th of August of each year. Demonstration of water saving technologies 200 lt water storage tank

54 Use of Tridle pumps for irrigation Treadle pump

55 b) Improved Stove it uses only quarter of fire wood

56 Collecting rice husks from paddy milling machines

57 Using rice husks to burn bricks

59 Participation in International Workshop on Mainstreaming Spate irrigation in Higher Education will be fruitful if at the end of workshop we will be able to produce curriculum which can put the acquired knowledge into practice and solve people’s problem at grassroot level. I can quote former United Nation Secretary General Mr. Koffi Annan who once said that in ‘Africa Knowledge is not lacking. What is lacking is to put the Knowledge into practice” Materials I brought with me which can be useful to workshop 1) Development of Standard scheme design document for Rainwater Harvesting Based Irrigation 2) Tanzanian National Irrigation Policy 3) Arusha Technical College (ATC) Degree in Irrigation curriculum
