The Global Futures and Strategic Foresight (GFSF) team met in Rome from May 25-28, 2015 to review progress towards current work plans, discuss model improvements and technical parameters, and consider possible contributions by the GFSF program to the CRP Phase II planning process. All 15 CGIAR Centers were represented at the meeting.

Modelling with ASIAFISH Supply: domestic supply + foreign supply Supply = f(output price, input price, other non-price factors) Import = Armington trade solution Demand: domestic demand + foreign demand Demand =f (product price, income, other factors) Export= Armington trade solution Model closing conditions: Supply == Demand

Editor's Notes

  • Other outputs/deliverables in 2015:
    Review of Literature on Seafood Demand and Supply: Recommendations for Building Country Specific Fish Sector Models
    Review of promising aquaculture technologies, climate smart aquaculture practices
  • Note: both qualitative scenario building and modelling approaches are used.
    Qualitative scenario: Develop narrative stories describing drivers of change, quality of change, change pathways, impact pathways, logic of impacts, uncertainties, complexity
    Modeling: Identify trends, direction of changes, magnitudes of change,…; Model simplifies reality, keep key structures and interactions
  • For this study the model will be disaggregated as:
    National aggregate = MRD + Rest of the country
    Total fish output = Aquaculture + Fisheries
    Aquaculture = shrimp + catfish + tilapia + carps +… (to include dominant fish types)
    Fish output (O) = A (area) x P (productivity)
     
    A will be given by CC scenarios: In a future where the MRD will be impacted by climate change and sea-level rise, and changes in hydrological conditions, the present spatial pattern of aquaculture may change.
    P will be given by aquaculture outlook reviews: Adaptation and advancement in aquaculture technologies via R&D will affect productivity.
    Deliverable in 2015:
    A WorldFish working paper reviewing past and current aquaculture economics and markets outlook in the Mekong Delta; ways forward (future scenarios for aquaculture economics and market outlooks); and suggestions for further research and modeling; Due Q4/2015
  • Theoretical foundation:
    The AsiaFish model is a partial equilibrium country specific fish sector model.
    Derived supply function approach: normalized profit function…
    Demand model follows three budgeting stages, final stage is the almost ideal demand system (AIDS)
    Assume that a group of closely related seafood products is separable from other foods. If commodities are assumed to be separable, multi-stage budgeting becomes possible.
    Trade code: Armington approach: foreign-domestic aggregate for production, consumptuon.
