  2. 2. Linearity: missing the main issue Fragile – robust – antifragile (Nassim Taleb)
  3. 3. MAIN MESSAGES 1. Buffering is an ancient answer to crises. 2. Groundwater is a natural buffer, use it economically and wisely, taking into consideration uncertainty in the planning. 3. Recent 65 years of modern large scale MAR-projects and thousands of years of small scale experiences offer challenging opportunities for future cooperation in practical and research projects.

  9. 9. Groundwater and Adaptation Measures  Managed Aquifer Recharge (MAR) provides multiple benefits:  storing water for future use  stabilizing or recovering ground water levels in overexploited aquifers,  reducing evaporative losses  managing saline intrusion or land subsidence, and  enabling reuse of waste or storm water.  Land use change – may provide an opportunity to enhance recharge, to protect groundwater quality and to reduce groundwater losses from evapotranspiration.  Integrating the management of surface water and groundwater resources (also to avoid mutual adversely impact) by regional integrated land and water management (ILWM – INRM)

Sharing experiences with information selection and sharing is meta- information, which can help you to solve your Groundwater Technical and Governance issues. 3. So: don’t hesitate to contact IGRAC.

  19. 19. MAIN OVERALL AMMAN MESSAGES (1) 1. Water buffering and land use change are ancient answers to crises. It are behavioural changes! 2. Groundwater is increasingly being used economically and wisely as buffer. MAR-Menarid examples are an excellent proof of this statement. 3. Much challenging work has to be done concerning proper scaling (both up and down) of MAR-implementation.
  20. 20. MAIN OVERALL AMMAN MESSAGES (2) 4. MAR-technology is well developed and will develop itself to further maturity combining conventional and modern methods. General guidelines are available and being updated. Improved effective and efficient exchange mechanism on national and international levels are needed especially concerning societal acceptance or integration of MAR. 5. Main scientific questions focus on (a) water quality issues, (b) optimization of water balancing, (c) planning and monitoring and (d) integration of technical, socio- economic, institutional and participation issues (=governance). Tailormade solutions are needed within generic frameworks.
  21. 21. MAIN OVERALL AMMAN MESSAGES (3) 6. Downscaling means bringing practical solutions to the lowest levels in a watershed (individual plants and trees and people), upscaling means bringing the solutionsto the highest levels of waterbasin planning (transboundary if needed). Integration of the two processes is an important challenge to increase the speed of success. 7. Cost effectiveness and cost recovery are important issues: especially in groundwater/MAR-practises full cost analysis (including long term development / sustainability issues) is needed. 8. The Sept 2014 Marrakesh IAH conference is a good forum to present results of the down&upscaled processes following our workshop (www.IAH2014.org). 9. Involve other MENA and Arab Gulf countries in the information exchange and next phases (viz. Abu Dhabi, Egypt, Lebanon etc.) . 10. Pay special attention to the need of the Gaza aquifer recovery issue, in combination with desal opportunities and economics. 11. Integrate findings with the International Groundwater Governance Project.
