Citation preview
Developing Improved Farming and Marketing
Systems in Rainfed Regions of Southern Lao PDR
Pheng Sengxua
Len Wade
Project Background
• Southern Laos identified for risk of hunger & poverty
• Government recognises an economy in transition
• Constraints to production, market risk, labour, …
• Potential with rice, livestock, diversification …
• Multidisciplinary team for strategic & adaptive research
• ACIAR Project CSE/2009/004 – AUD $5.16 m
Rainfed upland and lowland in southern Laos
Project Objectives
• Diagnose and integrated assessment of farming & marketing systems
• Optimisation, testing and adaptation of crop and livestock technologies and marketing/extension approaches
• Sharing of knowledge and pilot scaling out of varieties, crop and livestock technologies and marketing approaches
• Alleviation of constraints posed by drought and uncontrolled flooding
Project Strategy• Transect: lowland to upland, commodity to subsistence
• Systems research at 4 Research Hubs & associated districts
- Lowland Savannakhet (SVK)
- Transitional lowland/upland SVK
- Upland SVK
- Lowland Champassak (CPK)
• Adaptive on-farm research at 300 farms in 24 villages
• Scaling out in partnership with various groups
Project location
Research Themes
Socio-economic Consultation with DAFO
• Discussed district statistics, plans• Discussed key agro-ecological zones in
the district• Selected 3 representative villages for
each zone
Study the effect of supplementary water, fertilizer on rainfed lowland rice productivity
Multi-location lowland rice variety testing
Amendment of sandy soil with clays (Bentonite and organic matter)
Thasano station
Phonngam station
Trained PAFO and DAFO staffs on Experimental layout and data collection
Post rice crop in dry season
Multi-location test of lowland, aerobic and perennial rice varieties
Lowland
Perennial
Aerobic rice
GAP
Nutrient management in lowland rice field
Livestock and Forages Component
Germplasm evaluation
Establishment of forage plantation in farmers’ filed
Farmer participatory trials of WST in DS
To demonstrate WST (e.g. alternate wetting and drying or AWD) at the farmers’ fields in Savannakhet and Champassak;
To quantify the amount of water saved and water use efficiency by using AWD

Testing aerobic and submergence rice
varieties
Flooded tolerant variety Aerobic rice variety
Pond water monitoring
Knowledge sharing
Conclusion• Develop and demonstrate technology for
farmers
• Cooperate with ADB-IFAD project to investigate the farming technologies in that project areas
• Participatory research of rainfed lowland and upland farmers
Conclusion (cont)
• Impact of the project results: on livelihood, income and on sustainability of farming systems
• Improving capacity building of NAFRI, PAFO and DAFO (Master and PhD)
Conclusion (cont)• Adaptation of flooded and drought rice varieties
• Understanding the interaction of water x fertilizer x rice variety
• Found new forage varieties and technology for increasing livestock production and marketing option for farmers
