  1. Feeding the World Through Increased Irrigation Productivity and Innovation Water in a World of 7 Billion May 9, 2012 Roger Hohm, P.Ag. Head, Irrigation Secretariat Alberta Agriculture and Rural Development roger.hohm@gov.ab.ca

  2. Alberta’s Economy • Alberta’s economy depends on having a strong, global export base. • Our economy is therefore shaped by what happens in the rest of the world.

  3. Global Food Consumption(kcal/capita/day) 3200 3000 Population growth, combined with increased per capita consumption, will result in dramatic increases in the demand for food. 2800 2600 2400 2200 1965 1975 1985 1998 2015 2030

  4. Changing Diets • There is a shift towards more animal protein in the developing countries. • Per capita meat consumption in developing countries is expected to increase from 26 kg. in 1997/98 to 37 kg. in 2030. • This is a result of increasing economic development and per capita incomes.

  5. Alberta Livestock Exports • Beef Exports: $1.10 Billion • 75% of Canadian total • Pork Exports: $390 Million • Approximately 2.0 million head/year • Poultry Exports: $200 Million • 50,000 tonnes

  6. Implications to Cereal Production • 1 kg of chicken meat requires: • 3 kg of grain equivalents; • 1 kg of pork meat requires: • 5 kg of grain equivalents • 1 kg of beef requires: • 8 kg of grain equivalents;

  8. Water and food have been closely linked throughout history.

  9. Irrigated Food Production • About 40% of the world’s food, and 60% of cereal production is from irrigated lands. • Irrigation makes up about 17% of the total arable land base. • It is estimated that up to 80% of future food requirements will be met by irrigation.

  10. Projected Water Scarcity in 2025 Physical water scarcity Economic water scarcity Little or no water scarcity Seckler et al, 2002

  11. Alberta recognizes the need and opportunity to significantly increase agricultural food production to meet future world demands.

  13. Production and Diversification • Alberta’s advantages: • a large agricultural land base; • a strong dryland agriculture; and • a world-class irrigation system.

Private On-Farm Investment ~ $1.3 Billion Government Contribution = approx.$800 Million Irrigation District / Producers = approx.$190 Million TOTAL Capital Investment = approx. $990 Million Capital Investment in Irrigation Infrastructure Alberta Government & Irrigation Districts (Irrigation Producers) ICW / IREP / IRP - 1969 - 2011

  20. Public/Government Investment Through IRP • Less seepage • Less evaporation • Better water measurement and management • Reduced return flows

  27. Improved Irrigation Water Use Efficiencies … … Expectation for “Freed-up” Water! Irrigation Expansion Environmental Replenishment to Source “I’m Free!” Status Quo Water Users Other Uses

  28. Expansion Potential Water, not land, is the limiting factor restricting irrigation expansion. Interest by producers to irrigate far exceeds current water supplies in southern Alberta.

  29. Irrigation Expansion Potentialusing existing allocations • About 640,000 ha (1.58 m ac.) of land is currently irrigated in both organized districts and private schemes. • Irrigation Districts have voted to expand by 13% 70,000 ha (173,000 ac.) in the past few years

  30. Irrigation District Expansion Limits

  32. Any right answer Economic Development (e.g. Irrigation Expansion) Water “Conservation” for the “Environment” Saved Water

  33. Summary • World demand for food will grow at an increasing rate. • In the short and medium term, countries like Canada will be called upon to help meet the growing demand. • Alberta is in a position to diversify and increase productivity.

  34. Thank You Questions? Irrigation’s future in southern Alberta faces many water management challenges . . . but equally many opportunities!
