Improved agricultural water management in the Nile Basin: hydronomic zoning of Nile Basin

  1. 1. FU Berlin Improved Agricultural Water Management In the Nile Basin Hydronomic Zoning of Nile Basin S.S. Demissie, S.B. Awulachew, D. Molden & Poolad Karimi 1.  Introduction 4.  Hydronomic Zones Hydronomic  zoning  (water  management  zones)  helps  to  define,  characterize  and  develop  water  management  strategies specific to different conditions of the basin Classification  of  the  Nile  basin  into  similar  hydronomic  zones  facilitates  efficient  and  sustainable  application  of  adaptive and integrated water resources management. 2. Objectives Understand  the  characteristics  of  the  Nile  basin  using  different biophysical factors Classify  the  basin  into  similar  water  management  zones  that require identical interventions and strategies  3. Classification Factors Figure 1: Spatial patterns of  climatic factors in the Nile basin (left  to right): rainfall, potential evapotranspiration and humidity index. Figure 3: Hydronomic zones of the Nile basin with major farming  systems. 5.  Conclusions Five hydronomic zones and two major farming systems  relevant to water management are identified Environmentally sensitive zone includes wetlands and  protected areas (about 10% of the basin) The water source zones are located in the eastern  highlands and equatorial lakes regions Figure 2: Environmental and farming factors in the Nile basin (left  to right): wetlands, protected areas and farming system.
