Project Rationale and Objective
Project Rationale and Objective
Rationale for intervention
Growing use and increasing demand
Prevention is less expensive
Signs of scarcity and pollution in transboundary and national Hot Spots
Need to account for groundwater in water resource planning and management
Objective
Support Argentina, Brazil, Paraguay and Uruguay to jointly elaborate and implement a coordinated institutional framework for managing the transboundary Guarani Aquifer System for current and future generations.

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
Groundwater Management Groundwater Management RequirementsRequirementsImplement 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.

Project of declaration of basics principles and action guidelines for the Guarani Aquifer System under discussion (July 2004)
Strengthened commitment to jointly develop the Guarani (e.g. SC, NCs, GS-GAS, political support from national agencies…)
Multi country project management system under operation
Improvement of knowledge and participation of users and policymakers alike
Engaged Universities and NGOs Garnered international interest

SÍNTESIS GRÁFICA DE AVANCE DEL PROYECTO
Transboundary aquifer management depends on groundwater occurrence and subsystem special characteristics (knowledge importance)
Groundwater management must be focused on different aquifer funtions: heat, reservoir, water transportation, buffer, barriers, ecosystem maintenance... (concile protection, management and development)
Water uses must be integrated at each management level: LOCAL, sub national, national and regional
Project institutional framework involving water, environment and foreign affairs sectors has been adequate and must be strengthened with stakeholder participation in each national level
Effective of groundwater management requires strong cross-sector cooperation among national, sub-national and local governments and other different Organizations
Transparency, adequate financial resources and timing are critical elements in building participatory process..create constituency..keep momentum
Lessons LearnedGUARANI AQUIFER SYSTEM
Challenges – Looking ahead
Provide a catalytic input to the establishment of a framework for a sustainable transboundary aquifer management between the countries
Ensure the financial and technical sustainability of the monitoring and evaluation systems to be established by the project
Assist governments in defining and harmonizing 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 the aquifer, including prevention and conflict resolution.
