    11. 11. Key Technical issues to be addressed by the project Identify flux and architecture of the aquifer Determines provincial, municipal & local governments role Identify areas of recharge and discharge Prepare strategic action plan to prevent resource pollution and over exploitation Quantify recharge and discharge and flow behavior Establish quantitative targets to prevent over exploitation and landscape management practices Evaluate geo-thermal potential Integrate groundwater into energy plan for the region Assess vulnerability and risk Introduce risk mitigation and vulnerability reduction measures Determine water balance at the Guarani Promote integrated water resource management GUARANI AQUIFER SYSTEM
    12. 12.  Argentina  Decision making authority over water lies in provinces  Existence of provincial laws on water resources (thermalism under discussion)  Limited information: 9 deep wells, undefined Guarani western border  Brazil  Decision making authority over groundwater lies in states  Mineral, thermal and water bottling use governed by federal concession regime  National policy and state laws on water resources and groundwater (GW commitee and CNRH acts)  Considerable but dispersed information on groundwater (500 cities partially or entirely supplied by the Guarani)  Paraguay  Unitary State  Water resources law under discussion  Limited information available  more than 200 wells mainly for domestic supply  Uruguay  Unitary State  Existence of water law and decrees related to thermal uses  Considerable information available  Guarani Aquifer System Region: Institutional Background
    13. 13. Technical Base to GroundwaterTechnical Base to Groundwater ManagementManagement Characterization of geo hydrodynamic parameters, quality, level and flow of groundwater Identification of the recharge and discharge areas and compartments of the aquifer system Development of mathematical models of geo hydrodynamic behavior and risk analysis (vulnerability and potential pollutant on local and regional scale) Structuring of a network and an information system integrating groundwater date base (quantity and quality parameters, constructive aspects of wells, use and protection) GUARANI AQUIFER SYSTEM
    14. 14. Groundwater Management RequirementsGroundwater Management Requirements Implement and support monitoring network and an Information System with all data related to exploitation; Users database and public access to them; Increase the resource knowledge; Define priorities for exploitation and increase efficiency in a planned development policies framework; Define and to authorize maximum flow for exploitation and levels; Define and authorize location and distance between wells; Decide on new wells construction; Protect the environment, decreasing the impact of well construction and improving a convenient waste water disposal; Define protection perimeter and different exploitation areas; Promote training, education and diffusion about hydrological topics at different levels. GUARANI AQUIFER SYSTEM
    15. 15. The project will support policy makers on:The project will support policy makers on:  Formulating and harmonizing of riparian legal, technical and institutional arrangements  Mainstreaming best practices in groundwater management into each country’s development agenda  Establishing interactions between management of surface and groundwater under different aquifer conditions  The establishment of local management and planning, especially at transboundary (hot spot) areas GUARANI AQUIFER SYSTEM
    16. 16. Guarani Aquifer TDA basic frameworkGuarani Aquifer TDA basic framework c ACTUAL & POTENTIAL SITUATIONS WITH LOCAL TRANSBOUNDARY EFFECTS POSSIBLE SITUATIONS WITH SIGNIFICANT IMPACTS AT CATCHMENT SCALE • evaluation of incidence/ control of natural groundwater contamination (F, U, Rd, Rn) affecting use for potable water supply • contamination of potable waterwells due to inadequate urban sanitation and uncontrolled urban land-use • definition of strategies for efficient groundwater resource development and sustainable management • assessment of aquifer pollution vulnerability and appropriate protection measures for aquifer recharge areas • wetland impact and river baseflow reduction as a consequence of potential intensive groundwater resource development for agricultural irrigation • deterioration in the quality and rate of aquifer recharge as a result of extensive changes in agricultural land use and crop cultivation the adjacent problems could grow if regional agricultural policies and markets favour the intensive and extensive use of local soils and/or groundwater resources -- but only if current field investigations confirm (a) the present ecological role of aquifer discharge and (b) the hydraulic continuity of the aquifer system in the corresponding areas • evaluation of economic and efficient options for the use of the aquifer’s geothermal resources • reductions in the artesian and geothermal characteristics of the aquifer due to uncontrolled exploitation by geothermal wells APPROPRIATE LEVEL OF RESOLUTION SAG-PS and CSDP in service of the national and state organizations involved SAG-PS through intervention of CSDP with the countries and local institutions involved CSDP in consultation with supra- national organizations and with support of the SAG-PS GUARANI AQUIFER SYSTEM
    17. 17. Elements for the Development of theElements for the Development of the Institutional BaseInstitutional Base REGIONAL INTEGRATION Support the integration of development and protection policies for the aquifer in the countries STATE / NATIONAL REGULATION Development of the basics for the management of the groundwater and possible integration with surface waters LOCAL MANAGEMENT Integration of the hydric management policies and use of the urban / rural land GUARANI AQUIFER SYSTEM
    18. 18.  University Fund under execution (until Oct 2005)  Citizenship Fund under execution (until 2006)  Created forums for dialogue  Pilot local support committees and initial action plans under implementation  Main technical studies launched (transparency)  Multi country project management system under operation  TDA/SAP process under preparation (transition to the management phase)  Qualification program launched to support GW involved institutions Achievements to date… GUARANI AQUIFER SYSTEM
    19. 19.  Project of declaration of basics principles and action guidelines for the Guarani Aquifer System is being discussed in an Ad-Hoc Group of the Mercosur (since July 2004)  Strengthened commitment to jointly develop the Guarani (e.g. SC, NCs, GS-GAS, political support from national agencies…)  Improvement of knowledge and participation of users and policymakers alike  Engaged Universities and NGOs  Garnered international interest Achievements to date. GUARANI AQUIFER SYSTEM
    20. 20.  Managing transboundary groundwater has unique complexities: difficult to visualize common issues, different legal/institutional frameworks, international sensitivities  Groundwater has to be focused to make possible the overall water resource management at each level: local, sub national, national and regional  Management of groundwater requires strong cross-sector collaboration and cooperation among national and sub- national governments and other different Organizations  Strategic communication is needed early in project preparation  Garner support at local level – i.e. local coordinators at Hot Spots  Transparency, adequate financial resources and timing are critical elements in building participatory process..create constituency..keep momentum Lessons Learned GUARANI AQUIFER SYSTEM
    21. 21. Challenges – Looking ahead  Provide a catalytic input to the establishment of a framework for an integrated water resources management in the countries  Ensure the financial and technical sustainability of the monitoring and evaluation systems to be established by the project  Assist governments in harmonizing rules and regulations at country level that govern the sustainable management of the Guarani  Maintain the framework and best practices to be developed under the project in support of transboundary management of groundwater, including conflict resolution, at local level GUARANI AQUIFER SYSTEM
