# WATER AVAILABILITY FOR THE AGRICULTURE SECTOR?

<figure><img src="image_8.png" /></figure>
* Stronger water need for vegetation

* Increase in drought occurrence and severity

* Increasing need in the other sectors (domestic, industrial, environment preservation)

<figure><img src="image_9.png" /></figure>

## AGADAPT

* Improve Irrigation efficiency (The exact amount at the right time)

* Consider reuse water as an additional resource

* Better land planning (infrastructure, sharing water rules, reduction of costs, sustainable use of water, land use)

Deliverables :

model presentation and innovation (access,
specifications, state of the art);

**Implementation cost** (model license, data requirement);

Usefulness in demonstration case;

**Module Package** (data, model or access, link module with data base)

Local authorities, water agencies, farmers
organisations, service providers

## CRAU Case study :

**Piemont area** with an expected decreasing downstream flow used as an external water source

**An aquifer sustained by flooded irrigation** (80% of the recharge)

**An Aquifer exploited** by the domestic, industrial and agricultural sectors

**Urban sprawl**

**Stakeholders** : Water agency (share of the water between energy and agriculture), farmer organisation (hay production, irrigation channel management), groundwater syndicate, agriculture chamber.

* Ground water sustainability,

* Irrigation strategy : Minimum surface with flooded irrigation to maintain the aquifer

* Amount of water that can be uptaken in the aquifer

* Irrigation externalities : objective basis for cost sharing

* Hay production

# WP 3 Water Reuse

Provide terms of reference to make people more confident with reuse projects:

* provide a tool to analyzing reuse projects locally (aid for decision making).

analysis framework for the impact of reuse project(s) on the global water resource management under climate change scenarios

* provide arguments to water policies to refine/modify/adapt European regulations or guidelines and possibly to tend harmonizing them

* identify innovative business model to secure the financial viability of reuse projects for open system as well as closed systems (i.e. greenhouses).

Technical solutions addressed to greenhouses farmers to support Reuse and recycling

WP3 Water reuse (Suez, TNO, INRA)
# WP 3 Approach : site Audit

To provide term of reference for successful sustainable reuse water resources (i.e. reuse projects), as a mean to adapt water stress and climate change

* ✓ **by identifying** key success factors of existing European reuse projects: local drivers, regulations, business models, challenges (*ecological, technical, social*) and local innovations

* ✓ **by sharing** best reuse practices between European areas (north, south and east areas)

* ✓ Open field

* ✓ Greenhouses

Sites Audit

* ✓ 3 to 4 sites proposed, but **7 sites foreseen:**

* ✓ 1 already done

* ✓ 5 additional to be completed

* ✓ 1 others to be confirmed

* ✓ **Delay :**
  Irrigation to be operated in summer
