Accompanying the agrarian transition in LaosOpportunities and challenges for conservation agriculture in maize production areas G. Lestrelin & J-C. Castella
Research Questions• CA deemed knowledge- and capital-intensive, hence poorly compatible with smallholder farming (e.g. Erenstein 2003; Bolliger et al. 2006; Giller et al. 2009)• Dissemination should concentrate on “socio-ecological niches” (Giller et al. 2009: 31) where CA is the most likely to be adopted by smallholders• Two questions: To what extent can CA compete with more conventional forms of agricultural intensification in a context of smallholder farming? What is the value of a “socio-ecological niche” approach to the dissemination of CA?
Research SitesSayaboury Xieng Khouang Two CA research and development initiatives active between 2003 and 2008:
Research Sites• From 2003 to 2008: • Network of experimentation and demonstration plots • Establishment of CA farmer groups (44 villages in Sayaboury and 17 villages in Xieng Khouang) • Technical support to farmers and extension agencies• Various direct seeding mulch-based cropping (DMC) systems disseminated, including: Maize mono with Associations Rotationsresidues management food - fodder crops grass - legume crops
Methods & Data• Exhaustive village censuses: on household composition, land, labor, capital, farm equipment, etc.• Questionnaire surveys: Sayaboury: Annual surveys (2005-2008) among 2084 households in 21 villages; data on household livelihoods and adoption of CA Xieng Khouang: Rapid and detailed surveys (2009) among 600 households in 20 villages; data on household livelihoods, farm economics and adoption of CA; re-study of farming systems 2003• Qualitative interviews and focus groups: Village histories, perceptions of the advantages and limits of CA, constraints for adoption and dissemination, etc.• Land cover and land use change analysis (LANDSAT)• Scenario analysis: Technical and economic simulations with Olympe software
Results• Contrasted situations – CA dissemination efforts – Topography and ecology Geomorphology of southern Sayaboury province Steep slopes Productive Mod. slopes Schists Productive Schists Steep slopes Erosion-prone Sandstone
Results • Similar transitions and driving forces – Strong market demand for maize (w/ Thailand and Vietnam) 1,200,000 1,000,000Maize production (tons) 800,000 Maize 600,000 boom 400,000 200,000 0 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 Sayaboury Xieng Khouang Lao PDR
Results• Similar transitions and driving forces – Rapid agricultural expansion and intensification Land cover change in Xieng Khouang province (2002-2010) 2002 2006 2010 Forest land Upland crops (maize) Paddy rice
Results• Similar transitions and driving forces – Smallholder agriculture is still the norm Average rainfed land tenure per household Sayaboury (2008) 3 ha (1.1 – 5.3 ha) Xieng Khouang (2009) 2.2 ha (0.8 – 5.2 ha)

Conclusions• Two critical windows of opportunity for CA-related interventions in the maize production areas of Laos – Early stage of commoditization and intensification of agriculture: “Attractive option for smallholders willing to engage in commercial agriculture with a limited increase in production costs” – Latest stage of land degradation and economic diversification: “Economically- and ecologically-sound alternative to conventional intensive monoculture”• No particular “socio-ecological niches” or “hotspots” for dissemination BUT key moments for intervention along specific agro-ecological transition pathways• Appropriate timing + adequate research and extension endeavours CA can become a viable and accepted alternative – even in a context of small-scale farming
