Crop residue challenges in mixed crop-livestock farms
1. Crop residue use in crop-livestock farms challenges & options of mulching in Sub-Saharan Africa and South Asia 5th World Congress on Conservation Agriculture Brisbane, Australia, 26-29 September 2011 Diego Valbuena Olaf Erenstein Sabine Homann Tahirou Abdoulaye Alan Duncan Bruno Gérard Nils Teufel
2. mixed systems & SLP www.vslp.org Mixed systems = 2/3 population + food + value chains (Herrero et al. 2010) Biomass trade-offs : immediate demands & soil sustainability SLP : Bring livestock research on the agenda + links CGIAR Current project: crop residues use in mixed systems
3. objectives D escribe crop residue use in diverse mixed systems I dentify main challenges of mulching L ook for options related to mulching
4. crop residue use CA ideal situation http://www.iconpot.com http://www.openclipart.org
10. land & animals M-E1 H-B L-N1 H-I1 L-NG L-N2 L-Z L-MW M-E2 M-I2 L-MZ H-K land & livestock; livelihood for > ½ farms
11. income & production M-E1 H-B L-N1 H-I1 L-NG L-N2 L-Z L-MW M-E2 M-I2 L-MZ H-K Range of agriculture & self-consumption Extremes in S. Asia
12. CR more than mulch: cereals after Valbuena et al. submitted sites 0% 20% 40% 60% 80% 100% H-I1 H-B H-K M-E2 M-I2 M-E1 L-Z L-MZ L-N1 L-NG L-MW L-N2 other traded left/mulch feed ↓ feed ↑ mulch ↑ feed, ↓ mulch NG: feed-fuel MW: feed-mulch
13. CR more than mulch: legume H-K L-N1 % sold % fed % others L-NG L-N2 Legume residue high value or good for cooking (H-K). No mulching. In Southern Africa not mentioned.
17. intensification matters after Valbuena et al. submitted M-ET1 H-BD L-NE1 H-IN1 L-NG L-NE2 L-ZW L-MW M-ET2 M-IN2 L-MZ H-KN ↑ pop: ↑ intensity (area) H ↑ pop: ↓ communal land ↑ pop ↓ int./prod (area) & ↓ com. land: ↑ pressure on CR
18. other CA-related practices M-E1 H-B L-N1 H-I1 L-NG L-N2 L-Z L-MW M-E2 M-I2 L-MZ H-K > ½ area is tilled by animal; but also hand or tractor (not shown) Scarce legumes; market distortion & farming systems
19. results show that: CR are short-term resources: feed & Co. CR to mulch with lower pressure (very ↑ production; or ↑ production + ↓ demand), but practices need to change. With higher pressure: increase of production is needed. Each region has its own potential, challenges & options for more sustainable agriculture = no silver-bullet exists
20. work in progress household diversity linking better socio-economic, biophysical & institutional stakeholder involvement: R4D & demand-led R&D proposals
