  2. Outline of Presentation • Challenges and Resources • Ongoing Plans and Programmes • Needs

  3. Hydrologic & Conventional Basin

  4. Eco-regions (14) of the Conventional Basin Ecoregions of Active Watersheds

  5. Change in Climate • Less Rainfall in the Active Watershed

  6. Change in Climate • Temperature rise - an increase of 0.7° C or 2.5% in the Sahelian Zone and an increase of 0.4° C or 1.4% in the Tropical Zone. • A decrease of 3% or 6.5% in relative humidity • Less Flow to the Lake Chad - 50% decrease since 1972 • Localised periodic droughts in the Lake Chad Basin • Floods impacting cities and farmlands

  8. Available Capability/Resources • Distribution of Rainfall Stations • Each Member State has a network of rainfall stations • Manpower to monitor the stations

  9. Available Capability/Resources • Reference Discharge Stations • Eleven Selected Discharge stations with more than 50 years records • Manpower to monitor the discharge stations

  10. Programme & Plans to Address Impacts • Regional Strategic Action Programme & National Action Plans and an Investment Plan (IP) of the Lake Chad Basin (contains over 50 projects estimated to cost €107 million over the period 2012 – 2017). • Data Sharing Protocol agreed • Lake Chad Basin Water Charter to regulate water abstraction among users has been agreed.

  11. Lake Chad Basin Water Charter • Fundamental commitments of the Water Charter; • During low waters periods, reserve a minimum low water flow for the tributaries flowing into Lake Chad • During high water period, reserve a minimum amount of flood waters to ensure that the basin's wetland areas are inundated • Restrict the proportion of abstractions from the inflow to the Lake Chad • Adapt groundwater abstraction to aquifer capacity • When necessary, create fishing reserves in part of Lake Chad and/or its tributaries. • Share data and ensure smoothly-run exchanges of information

  12. LCBC Needs • Formalising the generation and exchange of information using GEO principles between Member States. • Data and models to enforce the Member States commitment to the Lake Chad Basin Water Charter • Data and information to monitor the implementation and progress of IWRM, actions and plans developed within the SAP framework.

  13. Specific Needs • Functions/Tools for Lake Chad WCI • Observation network • Initiate the adoption of new technologies in water observation • Build capacity by supporting the emergence of new institutional structures and mechanism for basin-wide coordination • Select adequate number of reference in-situ rainfall stations for calibration (upgrade, operate and maintain by LCBC) • Identify/establish more discharge reference stations(establish/upgrade, operate and maintain by LCBC).

  14. Specific Needs • Data Access • Acquire regular water related EO products over the Conventional Basin of the LCBC • Acquire Numerical Weather Prediction, Reanalysis, and Climate Projection capacity • Models • Develop rainfall-runoff model • Management systems • Forecasting and Early Warning System at short term and seasonal time frame • Decision Support System for Water Resources Development • Knowledge and data sharing portal

  15. LCBC Collaborative Framework • The following Multi-Disciplinary Professional Experts Committees are working with the LCBC to ensure collaboration by maintaining data quality, sharing data, information, exchanging ideas and experiences through regular meetings and publications. • LCBC Technical Committee • The Inter-Ministerial Technical Committees • The Water Resources Expert Committee • Committee on the Environment, Science and Planning.

  16. Implementation Proposal • Stakeholder Engagement • Identify and organise LCBC stakeholders, develop common vision, Share objectives, collaborations, achievements and feasibility, Identify SBA • Establish a working group in the LCBC • Identify suitable demonstration catchments • Identify and contact stakeholders in the selected pilot catchments

  17. Implementation Proposal • Establish Lake Chad Basin Water Cycle Integrator Steering Committee comprising key stakeholders from pilot catchments • Support the implementation of pilot WCI • Evaluate and disseminate result • Plan for basin wide expansion of the Lake Chad WCI possibly with private sector involvement • Development of a regional based water management knowledge repository based on the output of the Lake Chad WCI. • Consisting of analysis, prediction, early warning, risk assessment and decision support
