Crop residue tradeoffs in crop-livestock systems - Improving livelihood and environmental benefits from crop residues in smallholder crop-livestock systems in sub-Saharan Africa and South Asia: Regional case studies

  1. 1. Crop residue tradeoffs in crop-livestock systems“Improving livelihood and environmental benefits from crop residues in smallholder crop-livestock systems in sub-Saharan Africa and South Asia: regional case studies”. Bruno Gerard CGIAR Systemwide Livestock Programme ‘Mind the Gaps’ Meeting Naivasha, Kenya 27-29 April 2011
  2. 2. BackgroundSmallholders in mixed crop-livestock: very large fractionof farming enterprises in developing countries, cropresidues (CR) being a strategic production component(multiple use).Mixed crop-livestock systems are very dynamic,responsive to external drivers such as demographicpressure, development of urban markets and increaseddemand for crop and livestock products, climatevariability and change.In addition, the recent interest for bio-fuel productionexacerbates further the pressure on biomass inproduction systems.
  3. 3. Background (cont)The major tradeoff in most systems is the short termbenefits of using crop residues to feed livestock versusleaving the crop residues in the field to improve soilproductivity (nutrient balance, erosion control, and soilhealth).The study focuses on the decision making processes atthe farm/household level and attempt to capture thediversity/contrasts and recent changes in CR uses atvarious scales in order to better target technical,institutional and policy options to improve livelihoodwithout compromising long term system sustainability.

  5. 5. Research QuestionsWhat determines the decisions about crop residue use (current cropmanagement, agro-ecology, markets/institutions, resource endowments,dynamics,…)?What is the impact of those decisions on livelihoods and sustainability?What are the technological, institutional and policy options that wouldenhance livelihood and environmental benefits?
  6. 6. Research ApproachCombination of village and household surveys and modelling (tradeoff, productivity)(4 regions, 9 countries, 11 village clusters)Households surveyed in the four regions using stratified sampling, based onintensification level and market access.Village group survey to capture: i. Drivers and market access; ii. Communal feed resources; iii. Systems evolution in term of feeding strategies and soil productivity.Household survey to capture: i. Decision making for the allocation of crop residues; ii. Identification of soil fertility management practices and feeding strategies; iii. Retrospective questions to understand farm evolution/trajectories.Collection (primary and secondary data) of key bio-physical parameters (minimumdata set) to address sustainability issues.Contrast and trend analysis at household, village, system scales and identification ofpotential solutions under a range of scenarios.
  7. 7. From Dec 2009 meeting - progress on village level surveys and finalization of the household survey instruments - Workplan (conducting household survey, collecting secondary data,…) - Systems evolution/trajectories and scenario - Expertise on SA/Modelling missing (videoconference only)-> Need to conduct a workshop to bring together regions and system analysts(expertise from inside and outside the project)- Review approaches (combination socio-economic characterization and modelling)- Confirm we have the right tools to answer the project questions- Identify methodological, scale and data gaps and how to fill those gaps- Refine indicators- Develop collective workplan for analysis- Link this work with other on-going and future research (ie SLF, CRPs, new projects)- Follow-up project (Solution)-Publications….
  8. 8. This project (2010-2011)What determines the decisions about crop residue use (current crop management, agro-ecology, markets/institutions, resource endowments, dynamics,…)?What is the impact of those decisions on livelihoods and sustainability?Follow-up project (2012)What are the technological, institutional and policy options that would enhancelivelihood and environmental benefits?
