Mitigation in a Changing Environment

Experience in the Nile Basin

Nile River Basin

  • World’s longest river, 6700 km; covering 3.2M km2; 10% of Africa

  • Drainage from 10 countries: Burundi, DR Congo, Egypt, Eritrea, Ethiopia, Kenya, Rwanda, Sudan, Tanzania, Uganda

  • Population 200M, estimated to be 400M by 2025

  • Problem: Too much water in some places, too little in others

  • Issues: floods and droughts, land degradation, access to energy, erosion/siltation, food insecurity, poverty

  • Collaborative approach to problem solving: Nile Basin Initiative (NBI)

    • Inter-governmental organization, owned by the riparian governments, formed in 1999, funded by donors

    • Purpose is to bring all Nile basin countries together to develop the resources of the Nile Basin for the benefit of all – a mechanism to implement a shared vision for the future.

Our role
Our Role

  • Our participation started in 2000 with work for NBI on the Water Resources Management Project “to build analytical capacity and provide technical infrastructure to manage Nile Basin resources.”

    • Project Implementation Plan – Conceptual design of the technical components

    • Designed the NBI Resource Center for archiving and sharing information

    • Prepared the specifications for the Needs Assessment Study for the Decision Support System (DSS)

  • Currently part of a team that’s developing and implementing the DSS

  • Worked with NBI Subsidiary Action program for the Eastern Nile:

    • Design and Implementation Plan for the Eastern Nile Planning Model

    • Forecast System Design to support flood warning and data sharing

    • Developing internal/external web portal

    • Flood Risk Mapping in Pilot Areas for Ethiopia and Sudan

  • Nile basin decision support system
    Nile Basin Decision Support System

    Objective: Manage, process, evaluate and present data required to make informed decisions for water infrastructure and/or climate impact alternatives

    Current / future environmental data

    Central database and computer models

    Simulate impacts

    Current / planned water infrastructure

    Objective information for decision making

    Ethiopia and Sudan – Flood Risk Mapping Challenges and Solutions

    • Problem: Significant loss of life and property from frequent floods

    • Objective: Reduce future flood damages by producing tools for guiding infrastructure development and preparing for floods.

    • Involves: Data collection, modeling, flood hazard mapping, asset assessment, flood risk mapping

    • USACE HEC tools

    Results are encouraging … Solutions

    • Strong introduction of technology – IT, communications, GIS, data collection, data management and processing, analysis tools, simulation and optimization, multi-criteria analysis

    • Huge leaps in technical capacity building

    • Sharing of information – a monumental achievement

    • Lessons learned (ongoing):

    • Expectation management is key; explain what these systems can do and what they can’t do

    • Maintain stakeholder interest – show early results

    • Involve future users at appropriate levels; capacity building must involve cross-section of users

    Looking ahead … Solutions

    • Considerations for the future

      • South Sudan – New Nile State

        • Support for the Jonglei Canal?

      • Grand Millineum Dam – Ethiopia – Blue Nile

        • Storage and power comparable to Hoover Dam

      • Cooperative Framework Agreement

        • Formal distribution of Nile River water

    • Sustainability

      • Availability of data

        • Increase data collection?

      • Appropriate tools and technology

        • Continued donor support?

      • Strong technical capacity

        • Will they stay?
