Workshop Trade-off Analysis - CGIAR_20 Feb 2013_Group discussion_Complex vs simple 2
Complex versus Simple G510
General observations Results of complex models are difficult to interpret. Simplified systems Models for informed decision making/discussions Use of models ● Research tool ● Discussion tool ● Extension tool Complex versus simple Complex AND simple
Research approach Question Back of the envelop Answer? Solution Complex model Case Simple model Upscaling
Getting access to: Skilled people ● Important for all modelling studies, particularly for back of the envelope calculations. ● It is a perception that modeling is difficult High quality data ● What is needed? Better definition (AgMIP, K. Shepherd) Enough funds ● We wonder whether this is specific for modeling ● CRP’s are a good opportunity for long term work/model development.
Participatory approaches Participatory approaches should be combined with the modelling approaches. Models as discussion tools/extension tools part of participatory tools Skilled people are also a limitation for the participatory approaches. Participatory is a broad category with its (dis)advantages
Include new/different disciplines (psychologies/political scientists) So far cutting edge modeling upscaling Data limitations particularly on ag. management. Models should identify key drivers that can be collected. Risks Short term vs long term views Other modelling approaches?
