Main irrigation programme objectives:

1. Increase production of food and raw materials.

2 . Maintain population and land management in rural areas.

3 . Increase water efficiency.• Infrastructure measures.• Non infrastructure measures.

OBJECTIVES OF THE PRESENT IRRIGATION PROGRAMME


9


1. Production of food and raw materials.Food production implies the use of a large amount of water ( virtual water)

1 Apple = 60 litres 1 l olive oil = 4.000 litres

1 Lettuce = 85 litres 1 kg of beef = 15.000 litres

Average consumption : 2.600 l / per capita day = 950 m³ / per capita year.Catalonia : 7.150.000 inhabitants 950 m³ / p. year = 7.000 hm³/year.

Agriculture manages a large amount of rainfall water ( green water).

Rainfall : 1,1 M ha x 5.000 m³ / ha year = 5.500 hm³ / year

Irrigation in Catalonia uses a large amount of ground water ( bleu water) but not as much as green water.

Irrigation water : 2.000 hm³ / year

The deficit of virtual water in Catalonia is high. Considering an average use water efficiency of 60%.

Deficit : 7.000 hm³ - 7.500 x 0,6 = 2.500 hm³ / year

2. Maintain population and land management in rural areas.

Irrigation increases farm profitability and keeps population in areas with depopulation risk.

• Increases productivity :

Productivity in irrigated farms is 6,7 higher than in dry land.

• More even production and market supply guarantee.• Improves products quality.• Wider range of crops.

A.) Repair present infrastructures :

- canals, irrigation ditches, tubes, gates.

B.) Update water network :

- Implement pressure irrigation networks- Automation.- Flow control devices.

· General meters implementation.· Flow limit devices

- Water reservoirs to regulate canal flow

MESURES TO REDUCE WATER CONSUMPTIONMeasures on infrastructures :

C.) High efficiency irrigation techniques:

- Pressure tubes, water meters and automation.

- Basic irrigation techniques

- Controlled irrigation deficit.- Tracking and pumping of underground water.- Use of regenerated water. (Reus, la Sénia, la Fatarella, Blanes,

Valls, Borges Blanques, l’Alforja).

Traditional water concession is aprox 10.000 m³ / ha, but in new irrigated areas is only of 6.000 m³ / ha.

Less than 3.500 m³ / ha.

Increase water transport efficiency

Automatic pumping allows central control and a more efficient energy management.

Automatic irrigation devices and distribution control allows better adapt amount of water used to plant needs.

Regulatory watergate for constant water level, to get a constant water flow and a more efficient use of canal network. Catalunya- Arago Irrigation canal.

MEASURES TO IMPROVE WATER AND ENERGY EFFICIENCY.

Non infrastructure measures :

g

- Better information and farmers training :

- Irrigation courses in the agricultural professional schools coordinated by TàrregaCentre.- Course “ON LINE” in the RURALCAT website (www.ruralcat.com).- Agrometeorological network (http://www.ruralcat.net).- Weekly irrigation advices in RURALCAT website, e–mail messages or SMS.- Divulgation talks.

- Research and vulgarisation:

- IRTA . Research on deficit irrigation (vineyard , olives trees fruits).- Experimental plots DAR – REGSA – IRTA

· Essays on irrigation.· Tele control· Facilities evaluation

- Project for Ribera d’Ebre irrigation facilities modernisation.

- Modernisation scheme for Canal d’Urgell irrigation facilities.

Deputy Directorate for Rural Infrastructures. March 2009CONCLUSIONS

Catalonia is a country with the largest percentage of forest area in Europe. It has a high percentage of its surface occupied for non agricultural uses. Population density is also high (225 inhab/ km²) compared with 80 in hab./km² in Spain.

Modernisation of existing irrigation networks and new irrigated areas with high efficient irrigation techniques will reduce virtual water deficit.

Catalan labour force in agriculture is 2,2% (83.800 people).

Agriculture is an strategic economic activity to guarantee country food supply.
