1 RECENT EVOLUTION AND BACKGROUND
Background • Guadalquivir river: – – – –
South Spain Mediterranean climate 25% Spanish irrigated area Competitive agriculture (olive, citrus, field crops) – Average rain 580 mm – Average irrigation dose: 3800 m3/ha

2 IMPACT OF INCREASED WATER COST AND SCARCITY
Evolution of demand in Guadalquivir
Reduced dose Cost increase
No more irrigated area allowed since 2005
Technical change (water saving)
Increase productivity Demand is more ‘rigid’ 8
Evidence I: Water savings Guadalquivir mixed cropping Effect of measures: water savings 25% Effect of combined measures in modern irrigation (colored bars: volumetric tariff, cost increase, network improvement) is difficult to individualize role.
Irrigation units with coloured bars save water by three combined measures: - Volumetric pricing (“binomic” tariff = fixed cost + variable cost) - Increase water cost from zero (flat rate before reform) to (3-6 cent/m3) - Pressurized networks, improved irrigation on farm.
Result: average ‘wet’ water savings around 25%

Evidence II: Olive irrigated in Upper Guadalquivir (2008)
Water is expensive
Higher cost reduces water consumption.
