Key messages
Livestock are major water users in the Nile Basin.
Opportunities exist to use water more: • Effectively, productively, profitably & sustainably
• By integrating water and livestock
• In investment, development & management

Nile Livestock:Important water users
Livestock outnumber people.
50% of rainfall lost in grazing lands.
Animal feed > human food demand
Water for feed > water for food.
Current management degrades land & H20.– 50% of grazing lands.– Most rural domestic water contaminated.
Mixed temperate mixed crop-livestock systems - hot spots for action.

What is livestock water productivity (An entry point for INRM, IWRM & IRBM)
Benefits: Meat, milk, hides, traction power, manure, eggs, whole animal sales, drought security, wealth savings, etc.
Depleted water: Transpiration, evaporation, discharge & contamination.
Units: US$/m3 but alternatives exist.
(Only a few species considered so far)
LWP = ∑(Net beneficial outputs)
∑(Depleted water)

Conserve water(Vegetation and drinking management)
Limit animal access to open water and riparian habitats; use drinking troughs.
Rehabilitate & maintain rangelands; limit animal numbers & re-establish pasture

21
Balance feed & water distribution to increase LWP
Low LWP near water points– Overgrazing – Rain produces little feed.
Low LWP far from watering points– Drinking water constraints prevent grazing
Solution– Limit grazing near
watering points.– Develop new watering
points where surplus feed exists.
– Difficult but needed!

Implications for the Nile Half of rainfall lost as ET in grazing lands
– Manage ET for more benefits– Shift E to T
More depleted in mixed crop-livestock Potential to reduce water use by 50% to 90%.
4 helpful strategies (policy & practice)– Feed sources.– Adopt existing animal science tools.– Animal management to conserve water.– Feed-water-animal balance.
![Page 23: Nile Basin Development Forum Khartoum, Sudan, 17-19 November 2008 (A CPWF PN37 output)](https://reader036.vdocuments.site/reader036/viewer/2022062304/56813918550346895da0c229/html5/thumbnails/23.jpg)
23
Implications for the Nile Integrate crop-livestock-water development
for improved production, livelihoods and sustainability.
Identify areas to promote and reduce livestock production – Taking into account trade-offs with other water
users.

What next? Build on agreement between NBI & CGIAR.
Strengthen collaboration between livestock subsector, NBI & member states.
Improve coverage and quality of livestock & vegetation data sets for the Nile Basin.
Collaborate in policy development that ensures livestock contribute to poverty reduction, benefit sharing and sustainability.
Identify and encourage local level livestock-water management intervention options.
