CONSORZI DI BONIFICA E DI IRRIGAZIONE Italian drainage and irrigation boards

  • Consorzi realize integrated water management on

catchment basis protecting rural and urban land.

  • 85% of Italian agricultural production comes from

drained and irrigated areas.

  • 140 Consortia exist all over Italy.
  • 17,000,000 hectares (50% of Italy’s surface)

located in Consorzi districts.

  • 7,000,000 hectares under drainage (1,200,000

hectares depending on pumping stations).

  • 3,300,000 hectares under irrigation.
  • 181,312 km: total length of drainage and irrigation

channels.

  • 89 energy plants (mainly hydroelectric) produce

290,078,050 Kw/year.

The challenges for Consorzi of adaptation/mitigation of climate change

  • Use less water for irrigation and

increase quality and quantity of agricultural production.

  • Use irrigation water to recharge

aquifers and protect biodiversity.

  • Produce renewable energy to

balance the energy expenditures necessary to Consorzi operations. Energy produced is for self- consumption or for sale.

SUSTAINABLE IRRIGATION

  • Economic sustainability for farmers: less

cost for water

  • Environmental sustainability: saving

waters, recharging aquifers, protecting biodiversity

  • 3,300,000 hectares under irrigation:
  • 6% submersion irrigation (for rice

cultivation)

  • 23% flooding irrigation (gravity)
  • 51% under pressure (sprinkler)

irrigation

  • 20% drop irrigation
  • Ministry of Agriculture through Irrigation

Plan gives grant aid to Consortia’s projects for efficient irrigation.

  • European Union funds for efficient

irrigation after C.A.P. Health Check

Nothing worse that giving water for cultivation in the wrong quantity and at the wrong moment.

IRRINET is an expert system for irrigation developed by Consorzio di bonifica Canale Emiliano Romagnolo with the support of Region Emilia-Romagna and U.E. IRRINET is used on 160,000 hectars (23% of regional irrigation surface). IRRINET improves irrigation by saving 15 – 25 % waters and also increasing the quantity and quality of agricultural production. IN 2007 and 2008 8,000 FARMERS USING IRRINET HAVE SAVED 50 MILLIONS m3 WATER/YEAR.

Less water, less energy, better income for farmers.

In the Po river valley the groundwater level has been decreasing for 30 years. To restore the original level of the ground water it is possible to build special infiltration areas in farmland afforested with fast growing trees that will produce biomass Consorzio Pedemontano Brenta)

Consorzi di Bonifica stations: 79 hydroelectric power and 10 solar power. They produce in total 291,000,000 KWh/year (equivalent to 54,246 oil tons). Consorzio Est Sesia (Piemonte) has 29 hydroelectric stations producing 116,000,000 KWh/year. Rice cultivation irrigated by gravity through a huge network of rivers and canals. Many canals have been reshaped to create falls suitable to build energy stations.
