Halting Desertification in the Júcar River Basin

Preparatory Action on development of prevention activities to halt desertification in

Europe

Brussels, 16 February 2012

Elisa Vargas, Arancha Fidalgo

• Scale: Jucar River basin District, in the east of Spain (pilot RBD in the fist stage of the WFD implementation).

• Aim: obtain and assess socio-economic, environmental and climatic data, feed systems/models and provide recommendations to save water resources.

• Transfer results: dissemination to EU and non-EU countries through EMWIS.

Introduction

•Three main partners: EVREN (SME), EMWIS (International network), CHJ (Gov.).

• Environmental Consulting Firm (SME).• 23 years of experience.• Offices in Spain (Madrid, Valencia) and

Ecuador (Quito).• Areas of work:

• Water resources• Agronomy and forest resources• Coastal management• Land planning• Solid wastes• Sustainable touristic developments• Environmental Impact Assessment• Industrial environment• International projects

• Projects developed for Spanish Ministry of Agriculture, Food and Environment, River basin authorities, regional governments, international entities (EC, Plan Bleu-UNEP…).

• Hydrological planning.

• Rights, concessions, abstractions, discharges…

• Development of plans and programs for water saving, economic efficiency and environmental improvement.

• Definition of water quality and demand management action plans and programmes.

• Technical services related to the objectives and assessment to other administrations, institutions and individuals.

CHJ

•Data gathering (river discharge, rainfall, evapotranspiration, climate, groundwater, demands…).

•Data integration: propose methodology, gather and assess data.

•Assessment and results: recommend most feasible water saving options, propose management measures and targets.

•Dissemination activities.

Objectives of the Action

•Feed ECRINS, SEAA-W and future Blueprint optimization model. •Obtain useful water accounts.•Reach managers and local stakeholders by reviewing measures to save water.

1.Establishment of background and context. (Jan.-Feb.)

• EU strategies, policies, SEEA-W, ECRINS, Júcar RBD features.

2.Collection of data and contacts with administrations and other partners. (Feb.-Apr.)

• Data delivery feasibility, improvement of datasets.

3.Apply method by SEEA-W and ECRINS specifications. (Apr.-July)

• Disaggregation, detailed water resources balance, identification of measures.

•Assessment and recommendations. (Sept.-Dec.)1.Estimate optimizations and water saving potentials,

propose feasible targets.

•Meetings and deliverables. (12 months)•Dissemination and capacity building. (12 months)

1.Web-site section EVREN, EMWIS e-bulletin and website.

Tasks

•Meetings: • 4 main working team meetings (EVREN+CHJ).

• 3 Partnership meetings (EVREN+EMWIS+CHJ+Stakeholders).

• 2 Video conferences with EC officials.

•Reports• 3 main reports + recommendations.

• Other: brochure, web-site sections, dissemination through e-bulletins, non-EU session, event at the final Blueprint Conference.

•Timetable

Deliverables & timetable

•Surface: 42.851km2.

•Population (2009): 5,1 million.

•Mediterranean climate (average temp. 14-16ºC; average annual rainfall 500 mm).

•High season variability.

•Relevant groundwater resources.

•Water scarcity & droughts.

• Drought management plan since 2007.

•Desertification: overexploitation of aquifers and salinization of soils.

•Relevant demographic and touristic pressures.

•A river basin facing most of the water resources challenges!

Some of the most relevant water issues (identified in the draft RBMP).

• Water guarantee improvement and efficiency of traditional irrigation systems.

• Sustainable management of the Mancha Oriental aquifer.

• Overexploitation of GW in the Vinalopó area.

• Adjustment of ecological flows

• Ecosystem degradation

• Control of exotic species

• Adjustment and improvement of water treatment in specific municipalities

• Pollution control and eutrophication (Serpis and Albaida rivers)

• Flood risk reduction (low reach of Júcar River)

• Achievement of GES of the Albufera lake

• Water rights regularization

• Further assessment of wetland water requirements

• Priority substances follow-up
