4. Mixed crop-livestock Systems in Zambia
• Livestock = 40% of agricultural GDP
• IAPRI/CSO/MAL survey of 8279 households: 27% with cattle,
28% with goats, 75% with chicken
• Growing demand for livestock products. Projections 2050:
+71% beef, +129% milk and +80% small ruminant s meat
6. Feed balance for residues and grass
(dry season)
• Higher deficit
for crop residues
than for grass
• Higher distance

8. METHOD– SCENARIOS 2012-2030
Production
Cow milk, beef and goat meat
Adaptation
Transmission of inter-annual variability from biomass to animal products
Mitigation
GHG emissions and emission intensity
Vegetation (supply)
2012-2030 scenarios
• Baseline
• Drought
Livestock (demand)
Improvement options
• Animal husbandry & health
• Feeding practices (improved grasslands
and replacement of part of the CR)
10. Overcoming trade-offs between conservation
agriculture and livestock
• Sound assessment of biomass availability and demand (animal feed
intake and fuel) balance
• Allocation and efficient utilisation of crop residues, with minimum level
of vegetative cover assessed to conserve/enhance soil resources and
moisture in each agri- environmental and climatic condition, and
nutrient imports from animal manure added
• Identification of local alternative/complementary strategies to feeding
crop residues (legumes, grasses, tree fodder…)

11. Agroforestry systems
• Use of trees and shrubs as part of agricultural systems to
prevent soil erosion, facilitate water infiltration and decrease
the impacts of extreme weather.
• Also helps diversify income sources and provides energy and
fodder for livestock.
• Nitrogen-fixing leguminous trees, such as Faidherbia albida,
increase soil fertility and yields
• Not a recipe: a wide variety of systems and tress species to
consider in very different contexts
