Mediterranean Integrated System for Water Supply

About the project

There is a big pressure on the use of aquifers in the Mediterranean region for irrigation and desalination of water is still a costly and energy-demanding process. MEDISS addresses the issue of improving the quality of saline groundwater present in the Mediterranean area opening alternative irrigation for higher quality and more diversified cultivations (dates, citrus, etc.). According to the features and specific needs of the partner areas - Palestine (Jordan Valley), Jordan (Aqaba Governorate), Italy (Arborea) and Tunisia (Gabès) - MEDISS will test innovative solutions in the use of treated wastewater and desalination of brackish water. Specific awareness initiatives for end-users will challenge their reluctance toward non-conventional water resources (NCWR) and train them on Best Agricultural Practices. On the longer term, the project will contribute to reducing stress on freshwater, as well as costs for water supply. At the same time, higher productivity and diversification of crops will increase food security and income for farmers. Local communities and institutions will be empowered, contributing to behavioural change on the use of NCW and on environmentally and economically sustainable development.

What will be improved?

By increasing the surface of land irrigated with improved treated wastewater, MEDISS will lower the consumption of groundwater for irrigation, reducing pressure on stressed aquifers and raising the level of water available for other purposes. The use of less saline water will positively impact soil quality, allowing quantity/quality increase of agricultural production and diversification, shifting from lower values crops (forage, cereals) to more profitable ones (citrus, vegetable, arboriculture). In the long-term, MEDISS will bring economic development in the agricultural sector, increasing farmers’ profits and making them more stable. 

Who will benefit?

  • 160 farmers thanks to increased available water and water quality
  • 15 local organizations involved in water management (municipalities, local authorities, public agencies)
  • Local communities
  • National and regional policy-makers who will gain relevant data and good practices on innovative solutions for water supply

Expected achievements

  • 1 database on the water supply, water quality, soil composition and crops situation in the 4 target areas
  • 4 innovative solutions for NCW supply implemented for different irrigation and domestic purposes 
  • 1,450 hectares of land irrigated with treated wastewater 
  • 7 handover agreements with local authorities and water agencies to ensure the management of plants after the end of MEDISS project
  • 4 cross-border thematic practitioners and research networks on NCW supply for agricultural and domestic purposes
  • 15 local governance plans that integrate MEDISS NCW supply solutions
