Socioeconomic and environmental trade-offs for multifunctional landscapes: rice-fish Bac Kan

  1. 1. Socioeconomic and environmental trade-offs for multifunctional landscapes: rice-fish Bac Kan Elisabeth Simelton In collaboration with: Dam Viet Bac, Ngo The An, Nguyen Thi Hoa Email: e.simelton@cgiar.org Funding: FORMAS Sweden Technical workshop on Methods and Experiences in Climate Change Research and Assessments in Fisheries and Aquaculture Hanoi Sep 6, 2013
  2. 2. Rice-fish culture RISKS STRENGTHS Food Security Fish + No significant rice yield loss Fish sells +10.000VND/kg Socioeconomic & environmental synergies Biological weed control Less fertiliser (NPK) Biological pest control Less fish disease Tastier fish meat than pond Sensitive to extreme events Cold spell (tilapia) Water stress (flood/storm, drought) Adaptation? New rice varieties  Mechanisation  More ponds  less rice-fish Polluted water kills fish Theft Mitigation? Excess manure input?  Overfertilisation/methane emissions? Higher labour requirement? Source: Focus Group Discussions 2012-13; Literature review
  3. 3. Rice-fish • Globally Important Agricultural Heritage System (GIAHSFAO) • Autonomous adoption: widespread without Government/project support • Multi-functional system – economic diversification (WB) – diversification of environmental functions (MEA) • Climate-Smart Agriculture (FAO, CGIAR) – Food security & livelihood improvement – Adapted for climate change – Mitigation (sequestration/reduced emission) What are the barriers for adoption of rice-fish?
  4. 4. Outline • Study site, Data & methods • • • • • • 3 policies influencing rice fish (Bac Kan) Who does rice-fish? Why? Why not? Policy recommendations Research gaps Adoption barriers - 3 lessons learned Conclusions

  14. 14. Rice-fish: 3 knowledge gaps • Adaptation: Reducing exposure to extreme events – Flood risk (storm) – Cold spell – alternatives to tilapia? • Food security: consequences of national rice food security targets on integrated systems – Hybrid rice  More intensive agriculture  less rice fish • Environmental Services: Linking PES to all land uses – – – – Mitigation: Nitrogen leaching? Methane emission? Clean water: Agriculture water pollutants Soil erosion: paddy fields are sedimentation traps Ecotourism
  15. 15. Lessons learned: 3 adoption principles multifunctional farming system • Additional component(s) add value, do not interfere with current land uses on the farm or land use policies • Economic and environmental risks and benefits are well known and rational to the farmer • Flexibility. The new system generates annual outputs and enables multiple possible outcomes
  16. 16. Conclusions • Rice fish is an important component of food self sufficient households – Provides food (quantity & quality) – Generates income • Rice-fish has socio-economic and biophysical synergies – Diversifies income and land use – Negotiable within (most) current land use policies – Potential PES for all land uses • Potential trade-offs – National food security policies (intensified paddy culture) – Mitigation - Uncertain GHG-emissions? – Adaptation - Uncertain under extreme events
