Methodologies and best IWRM practices for joint management of groundwater and surface water at basin level
INBO has published methodological handbooks on the conjunctive management of groundwater and surface water through IWRM at basin level-**- “Toward a Joint Management of Transboundary Aquifer Systems” (2010),**- “Integrated Water Resources Management in the Basins of Transboundary Rivers, Lakes and Aquifers” (2012),**- “Water and Climate Change Adaptation in Transboundary Basins- Lessons Learned and Good Practices” (2015).**These documents designed with expert partners (UNECE, UNESCO-IHP, GEF, GWP, AFD, etc…) promote methodological guidelines and share practical experiences on each step required for a joint management.**The key principles of surface water management are demonstrated to be also relevant for groundwater management, especially in the case of transboundary aquifers-**- Monitoring, water information and knowledge,**- Institutional capacity building,**- Professional training of stakeholders of all levels of qualification,**- Design and implementation of basin management plans and programs of measures.**This review include concrete case studies, illustrating successes in implementing the provisions of the 2008 Draft articles on the Law of Transboundary and IWRM principles- cooperative management of the French-Swiss Genevois aquifer, Mexico on the involvement of all users (farmers, industries, municipalities and state governments) in “technical committees for groundwater” (COTAS) created within basin councils, Sahara and Sahel Observatory on water-saving agricultural practices in the North-Western Sahara Aquifer System and on the development of a water information system covering the Niger river basin and its related Iullemeden-Taoudeni-Tanezrouft aquifer system, Guarani transboundary aquifer and the involvement of the Intergovernmental Coordinating Committee of La Plata river or the Russian-Estonian Lake Peipsi aquifer system on the use of mathematical modeling to understand hydrological relations between groundwater and surface water.****In conclusion, these methodologies and case studies are highly valuable capacity building tools for institutions in charge of implementing IWRM of both groundwater and surface water at basin level. They deserve to be broadly disseminated.**
