Sustainable Water Resource Management in Litani Lower Basin: A Case Study

This case study from Gumpoldskirchen 18-20 May 2006 explores the challenges and solutions for sustainable water resource management in the Litani Lower Basin. It delves into stakeholder involvement, land use changes, water resource management objectives and instruments, as well as constraints and future recommendations for the region. The study covers topics like demographic change, river use, agriculture, institutional frameworks, stakeholder engagement, GIS data, land use changes, and water quality issues. The report also outlines proposed objectives for enhancing water efficiency, river exploitation, pollution control, and reducing losses. Recommendations for instruments to achieve these objectives include irrigation canals, dams, waste water treatment plants, and awareness campaigns. Challenges such as data calibration, water quality assessments, and future works on baseline scenarios are also discussed. The study concludes by emphasizing the importance of collective efforts and continued collaboration among stakeholders for sustainable water resource management in the Litani Lower Basin.

  7. Agriculture ELARD, 2001 Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  8. Institutional Framework* Planning/Supervision MINISTRY OF ENERGY AND WATER Reports to Reports to • INFRASTRUCTURE • Irrigation (Qasmiyye canal, Litani canal 900) • Recreational South Lebanon Water & WastewaterEstablishment Litani Water Authority Reports to • WATER FLOW • WATER QUALITY • DOMESTIC WATER • from Litani River Water Authorities (Jabal Aamel) * “Decrees 5469/1 -5469/16- 5469/25- 5469/40 (1966); Law 121/2001” Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  9. Stakeholders Pub. Auth NGO • Workshop in september 2005 • Workshop report sent to all the stakeholders • Update of stakeholders’ list and information/ (27 qs and 56 stakeholders) • Analysis of proposed objectives and constraints from the workshop • Presentation of the Project progress scheduled with the Litani Authority • Follow up second workshop in August 2006 Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  10. WP05: GIS DATA Metadata Input Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  11. Land Use Change (level) Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  12. Land Use Change Increase in Urban Fabric Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  13. Land Use Change (Banana/Citrus) 1998 Decrease in citrus and banana 2005 Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  14. 1998 Land Use Change (Olives) 2005 Decrease in Olives Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  15. WRM Baseline Scenario Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  16. Rainfall Runoff Model (15 subcatchments) Problems with the calibration data Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  17. Criteria (based on issues qs and ws) Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  18. CONSTRAINTS • Environmental Level flow in the river in some portions (especially at the coast) • Supply meeting consumption demand • OBJECTIVES • Increase water demand efficiency • Better exploitation of the River (balanced exploitation) • Control sources of pollution • Decrease losses to the sea Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  19. INSTRUMENTS • Irrigation canal (8.05m3/sec agricultural use and 0.64 m3/sec domestic) cost of 132Million Euros • 2 Dams (128 Millions m3) • Waste water treatment plant(s) • Hydroelectrical plant(s) • Hill lakes • Infrastructure • Update legislation/improve enforcement • Decrease violations on River • Legal • Water pricing • Improvement of the canalization (decrease of losses) • Management • Awareness campaigns • Irrigation technologies (surface irrigation to drip or sprinkle) • Alternative crops (less water consuming) Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.

  20. PROBLEMS • RRM model (daily data for control points on subcatchment, data cannot be calibrated to a control station) • Water Quality (Stream cannot be used since there were no levels of BOD detected during sampling in the River; potential campaign in summer(?)) FUTURE WORKS • Finalize Baseline scenario (data, economic information, etc.) • Input to WP04 (Instruments and water technologies, cost of infrastructure on the River • Optimization runs • Second workshop to quantify constraints, validate scenarios, in August 2006 after the progress report Intro. The river basin Stakeholders WP05 Landuse change WRM Obj/Const Instruments Conc.
