1510 - Farmer Adaptation of System of Rice Intensification (SRI) Methods in the Lower Mekong Basin region

  1. 1. Farmer Adaptation of System of Rice Intensification (SRI) Methods in the Lower Mekong Basin Region Dr. Abha Mishra Co-Director, ACISAI Center, Asian Institute of Technology (AIT), Thailand, Team Leader, SRI-LMB SRI-Rice, Cornell University, Ithaca, New York, 12 October 2015 12-10-2015
  2. 2. SRI @ AIT SRI at AIT Why SRI at AIT  Global interest  Major attraction at farmers‘field;  Asia: largest producer of rice;  Asia: largest consumer of agricultural water;  Asia: 50-70% farmers are engaged in rice farming;  Asia: Food security is linked to rice production; SRI: Provides larger ambit to address the multiple issues associated with sustainable agricultural development in the context of climate change
  3. 3.  Out of 65 millions inhabitants, 60 millions reside in LMB  Agriculture, fishing and forestry employs 90%  Rice cultivation in 10 million hectare out of which 6 million hectare is rainfed  wide spread poverty in the region, mostly smallholder farmers who are engaged in rice farming in rainfed area are poor  Costly farming techniques are not applied with the given level of uncertainty  Rice contributes 75% towards people per capita calorific supply  Food insecurity  Productivity of rice is low 12-10-2015 Why LMB region
  4. 4. Characteristics of the rainfed areas Household characteristics  Av. Landholding is 1-2 ha  Average age of farmers is 50+  More than 70% are women  Grow only one crop of rice in wet season with very limited diversification  Subsistence type rice farming in Cambodia and Laos where as in Thailand rice is grown for export and now also in Vietnam  Average rice yield is 2-3 t/ha  Increasing households loans  Increasing out-migration of farmers  Food insecurity 12-10-2015
  5. 5. WBI workshop and genesis of the SRI-LMB  Goal • Development of adaptive measures to protect against climate change so as to address the food security and livelihood issues of rainfed smallholders farmers in lower Mekong river basin (LMB) countries  Action • Develop local, national and regional platform for joint initiative and coordinated actions • Increase crop yield, productivity and profitability on sustainable basis at smallholders farmers’ field in rainfed areas of LMB region. Partners stimulate and support local innovation through farmers participatory action research http://www.ait.ac.th/research/workshop-reports/AIT-WBI-Workshop- Report.pdf/view#.VWafG820jjA 12-10-2015
  6. 6. SRI ‘Menu’ for change Capturing farmers imagination by enabling them to get higher yield with reduced external inputs, and fuelling their capacity for innovation  Offers low cost solution  Doesn’t require external inputs  Practices are amenable to farmers experimentation  Follows agro ecological principles  Transplanting younger and fewer seedlings/hill  maintaining wider spacing  Avoiding continuous soil saturation  Applying compost as much as possible 12-10-2015

More than 120 sets of experiments @ 62 FPAR sites in 2014 Cambodia & Thailand In five provinces - 13 districts were rainfed and 2 were irrigated - Broadly two options were explored using experiments: SRI demonstration (SRI-D) as a ‘test site’ and (2) Integration of SRI practices with existing cultivation practices as learning plot for location specific adaptation (SRI-T) - And compared with existing conventional management practices (CP) in target area set up as a farmers’ practice. 15 districts, 3 in each province 12-10-2015

  32. 32. Factors affecting adoption  Less input use, higher yield and higher net return (+)  Quality of grain (+)  No lodging (+)  Less pest and diseases (+)  Unreliable weather and water availability (-)  Market instability and price volatility (-)  No incentive for good work (-)  Transplanting & labour use (Thailand) (-) 12-10-2015
  33. 33. Factors that will speed up SRI adoption • SRI with direct seeding with low seed rate (Thailand) • Support for critical irrigation • Better incentive and market stability • Green SRI from farm to fork REGIONAL REVIEW & PLANNING WORKSHOP REPORT Siem Reap, Cambodia 02-03 June 2015 Sustaining and Enhancing the Momentum for Innovation and Learning around the System of Rice Intensification (SRI) in the Lower Mekong River Basin (SRI-LMB) This project is funded by the European Union A project implemented by the Asian Institute of Technology the European Union http://www.sri- lmb.ait.asia/country/doc/Regional%20Review%20and%20 Planning%20Workshop-REPORT%20(02- 03%20June%202015).pdf 12-10-2015
  34. 34. Conclusions and way forward • Efforts to make SRI knowledge and practices available on a wider scale can raise productivity and incomes and in turn can address food insecurity of the broad population of smallholders without further deteriorating the environment. • Economic productivity was higher in rainfed compared to the irrigated systems therefore only a small investment is needed to make the rainfed system more productive and resilient. • Bringing poor smallholding farmers more directly into the process of economic growth can offer more hope at both micro and macro levels. 12-10-2015
