Workshop. In the Guideline on p3-27, Scheme efficiency or Irrigation efficiency is roughly esti- mated. Sufficient means farmers have the sufficient experience of irrigation practices with unlined canals. Poor means they do not have sufficient experiences. HORIZONTAL EXPANSION & VERTICAL EXPANSION under Irrigation Table-2 Irrigation Efficiency by Scheme Condition Proposed canal condition Lined Unlined For a long time we have been putting more efforts to horizontal expansion and Farmers’ experience - Sufficient Poor putting less effort to vertical expansion while vertical expansion is less expen- Irrigation efficiency 0.40 0.30 0.25 sive compared to horizontal expansion. When a new land is put under irrigation that is horizontal expansion and when operation and maintenance is intensified so that production and productivity is increased sustainably is vertical expansion. From Project Manager –3-, TANCAID Consider to have average production of irrigated paddy of 4 tones /hector but Irrigation development in Tanzania can move faster if and only if there production can go up to 10tones /Hector under intensification of operation and are serious commitments of all stakeholders including Government maintenance. It is less expensive to produce 6 tones more from one hector com- Staff private partners and beneficiaries. Individual commitment of pered to expansion of a new area of irrigation which include construction of new each stakeholder will be the agent of change and will increase the pace irrigation infrastructure which can produce 6 tonnes.
