  1. Irrigation NZ “Promote Excellence in Irrigation” • Advocacy & Leadership • Education & Training • Research & Innovation Membership Schemes, User Groups & Individual Irrigators – 60% of NZ’s irrigated area (720,000ha) Technical & Trade – Over 150 service industries (& government)

  2. WHERE WE IRRIGATE

  3. CLIMATE CHANGE & DROUGHT Drought Change 1980-1999 to 2030-2049 “Long, dry spells are forecast to double by 2040 as temperatures continue to rise and New Zealand heads towards a more Mediterranean climate”. NIWA 2013

  4. Irrigation 10,000 10,000 Existing = 720,000ha Canterbury = 65% Otago = 18% Hawke’s Bay Marlborough Tasman Wairarapa Bay of Plenty Northland Pukekohe Gisborne Manawatu Even West Coast!! 10,000 30,000 250,000 50,000 30,000

  6. Cost challenge Community infrastructure = increased cost Capital costs ($/ha) • Scheme (off farm) $5,000 - $12,000 • On-farm irrigation $4,000 - $10,000 • On-farm development ? Water Charges ($/ha) • Interest & Principal $700 - $1,700 • Scheme operating costs $100 - $500 • Total $800 - $2,200 Additional gross profit required = $1,000/ha

  7. Making irrigation pay • Adding water alone not economic • Need to intensify farming system • Higher stocking rate • Higher crop yields • Store => Finishing • Irrigation development = rapid change in land ownership and farming systems- • Livestock => intensive cropping • Livestock => dairy farming • Mixed cropping => viticulture or horticulture

  8. Major hurdle - can I intensify? • NPS Freshwater Management 2011 • Values, objectives and limits for quantity & quality • Allocation for water & nutrients • Irrigators need demonstrate operating to a standard – Good Management Practice • Accountability – Auditable Farm Environment Plans • Creates additional cost to Business-as-Usual

  9. SMART Irrigation Sustainably Managed, Accountable, Responsible and Trusted

  10. System Can Apply Water Efficiently • Developments and upgrades:

  11. Use of Water

  12. Provide Proof

  13. A Co-ordinated Approach
