A presentation from the WCCA 2011 event held in Brisbane, Australia.

1. Co-innovation of family farm systems in Uruguay: the role of farm modeling 3 rd farming Systems Design Conference Brisbane 26-29th September 2011 Dogliotti S , Aguerre V, Chilibroste P, Casagrande M, Rossing WAH Facultad de Agronomía , Montevideo, Uruguay Instituto Nacional de Investigación Agropecuaria, Uruguay Wageningen Centre for Agro-ecology and Systems Analysis (WaCasa), Wageningen University, The Netherlands

2. The learning cycles Model based exploratory study: alternative development strategies 2002-2003 Discussion of results with stakeholders: motivation and funding for a participatory research project 2003-2004 Co-innovation of vegetable and mixed farm systems: close farmer-researcher interaction on 16 pilot farms 2005-2010 Model based exploratory study: potential for improvement within <> farm types and scenarios 2010-2011 Discussion of results with stakeholders: training of extension agents, research agenda, policy briefs 2011-2012 Characterization & diagnosis of vegetable farming systems: On-Farm sustainability assessment 1997-2002

3. The unsustainability cycle Decreasing vegetables prices Decreasing Family Income Decreasing soil quality Increasing use of irrigation and inputs Increasing production costs Increasing prices of inputs Increasing crop yields ? Intensify and specialize the farm system

4. The unsustainability cycle

12. Exploring potential for improvement: soil erosion and income Soil erosion and family income for pilot farms 1 and 2. Initial refers to the situation before implementation of plans, Actual to the results of 2009-2010, and Potential to the lowest attainable erosion level without reducing Actual family income based on explorations with Farm IMAGES

13. Exploring potential for improvement: soil erosion and income Trade-off between soil conservation and family income for pilot farms 1 and 2 explored with Farm IMAGES.
