Improved Agricultural Water Management In the Nile Basin
Hydronomic Zoning of Nile Basin

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

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
