(Stats NZ 2003) • 58 % of all water allocated nationally for consumptive use. (LE 2000) • 70 % of all irrigated land in New Zealand. (LE 2000) • Canterbury allocation predominantly irrigation.

(LE 2002) – Gross potentially irrigable 1.3 m Ha. – Net potentially irrigable 1.0 m Ha. Presentation to CSWS Darfield 2006 Agriculture, Irrigation and the Canterbury Economy. • Agriculture has a declining share of NZ ‘s GDP. National GDP Share by Broad Industry Group 2004 Agriculture 5% Service Industries 70% Presentation to CSWS Darfield 2006 Forestry, Fishing, Mining 2% Goods Producing Industries 23% • Agriculture, Irrigation and the Canterbury Economy. Canterbury's economy is more dependant on agriculture than the national average. Canterbury Value Added by Broad Industry Group 2004 Forestry, Agriculture 8% Service Industries 66% Presentation to CSWS Darfield 2006 Fishing, Mining 1% Goods Producing Industries 25% • Agriculture, Irrigation and the Canterbury Economy. Canterbury’s Value Added derives from 3 main sub sectors. Canterbury Agricultural Value Added by Sector 2004 Dairy 28% Sheep and Beef 32% Presentation to CSWS Darfield 2006 Mixed Cropping 18% Ag Services 5% Other 8% Horticulture 9% Agriculture, Irrigation and the Canterbury Economy. • The Agricultural sector contributes about 10-11% of Canterbury’s employment. Canterbury Employment by Broad Industry Group 2004 Primary Industries 11% Service Industries 65% Presentation to CSWS Darfield 2006 Goods Producing Industries 24% Agriculture, Irrigation and the Canterbury Economy. • Canterbury’s employment is more evenly distributed throughout the sectors. Canterbury Agricultural Employment by Sector 2004 Dairy 17% Mixed Cropping 22% Sheep and Beef 29% Presentation to CSWS Darfield 2006 Ag Services 10% Horticulture 11% Other 11% Agriculture, Irrigation and the Canterbury Economy. Linkages through to goods producing industries means that the contribution of the agricultural sector increases. • Direct plus indirect effects; – Value added 8.4% to 11.7%. – Employment 10.2% to 13.2% Presentation to CSWS Darfield 2006 Agriculture, Irrigation and the Canterbury Economy. The contribution to Canterbury’s economy from irrigation is significant. (Butcher 2000 ) – One third of value added. – Likely to be higher now. – 3,600 jobs on farm attributable to irrigation. – Share of jobs supported by irrigation less than the share of value added. Presentation to CSWS Darfield 2006 Agriculture, Irrigation and the Canterbury Economy. • Net contribution to GDP per Ha irrigated in Canterbury 2002 / 03 is the lowest of all regions. (Doak 2004).

Social community change is massive. Quality measures are positive. Impact on size and form of the business community / economy is significant. Presentation to CSWS Darfield 2006 Social and Economic Impacts Opuha Dam Ex Post Impacts (Harris 2006) On Farm Impacts • Total revenue is 2.4 times as high at $2,073 / ha for the irrigated farms than the dryland at $862 / ha. • • The ratio of Farm Working Expenses to Total Revenue is very similar between the dryland and irrigated properties (76% and 73% respectively). Cash Farm Surplus as a proportion of Total Revenue is similar for the two farm types at 24% and 27% respectively but the dollar value of the surplus on the irrigated farms is substantially higher. Presentation to CSWS Darfield 2006 Social and Economic Impacts Scheme Wide On Farm Impacts (16,175 ha) • • • • • Total Farm Revenue increase of approximately $40 m / annum. Total Farm Working Expenditure increase of approximately $28 m / annum. Cash Farm Surplus increase of approximately $12 m / annum. Net Trading Profit after Tax increase of approximately $3 m / annum. Irrigated farms generate 2.0 times as many jobs, 2.3 times as much value added and 3 times as much household income per ha as do dryland farms.

Presentation to CSWS Darfield 2006 Future Prospects “ It may well be that community irrigation schemes provide one of the most potent forces for regional development and social stability in agricultural areas of New Zealand” Presentation to CSWS Darfield 2006 Future Prospects • • New large scale irrigation developments are unlikely to occur in Canterbury without Government support. The rationale for this support is National and District policy objectives which promote vibrant, healthy and sustainable rural communities. Presentation to CSWS Darfield 2006 Future Prospects Figure 1: Conceptual representation of the sequence of water resource development for irrigation 2010 2003 Presentation to CSWS Darfield 2006 Future Prospects • • • As marginal cost of new development increases we will soon reach the point where cost exceeds marginal benefit then; forced to re look at existing (lower cost) water allocation and use and achieve efficiency gains (allocative, conveyance, application, economic) in order to facilitate redistribution and; re examine demand variables from an economic perspective. Presentation to CSWS Darfield 2006 Future Prospects Regional Economic Impacts of Water Allocation and Reliability. (Harris 2005) $180,000,000 $160,000,000 $140,000,000 Regional CFS $120,000,000 $100,000,000 Region Total without capital costs Regional total with capital costs for new irrigation $80,000,000 Existing Area $60,000,000 Dryland $40,000,000 $20,000,000 $0 0 10 20 30 40 Equivalent Irrigation Allocation (cumecs) Presentation to CSWS Darfield 2006 50 60 Future Prospects • • • • • Cash farm surplus for all existing irrigators decreased as reliability decreased. Extra water was redistributed to new irrigators at the lower reliability. Regional Total CFS (GDP) increases as reliability decreases. Regional Total CFS with capital included (net benefit) increases as reliability decreases. Spreading the water further at lower reliability increases public and new irrigator benefit at a cost to existing irrigators.
