RESEARCHProject: Evaluation of strategies for the design and management of sustainable agroecosystemsObjective: To promote research to understand, develop, manage and evaluate agricultural systems in the context of sustainable agriculture.Lines of work:• The use of mixing and consociation of species in the production of oilseeds and its role in the sustainability of extensive production systems.• Evaluation of energy efficiency systems. Tool for the design of sustainable production strategies.• Design and evaluation of agro-management strategies of weeds in oilseed crops.• Weed management in flax. Evaluation of crop-weed competition in agro-ecological approach (Thesis Griselda E. Sánchez_Vallduví).• Analysis of the impact on the sustainability of the spread of rapeseed and barley in place of wheat in the sequence wheat/soybean 2nd in the locality of Tres Arroyos (Thesis Adriana M. Chamorro).
TEACHINGObjectives:•Promote the ability to recognize, describe and characterize oilseeds and the systems that they integrate.•Display the interactions between environmental, ecological, genetic, and technological factors and their effects on the oilseed crops and the agroecosystem.•Develop criteria for sustainable agro-ecological management.•Encourage critical capacity for responsible decision-making and an awareness of their impact on production, environmental and human health in different ecological and socioeconomic contexts.
FINAL CONSIDERATIONSThe development of sustainable farming systems should be a prime target for farmers, academic institutions, scientists and politicians. In this context it is imperative:
- To reconsider and rethink seriously the reductionist model of agricultural production systems.- Keep in mind the long term effects that it can have on human and environmental health.- Reconciling productivity with economic, ecological and social aspect.- Ensure the security of health foods from different socio-economic sectors.
There is a need for commitment and dedication by those involved in research, teaching, implementation, the productive sector and political power, to guide efforts and resources toward a more sustainable agriculture.

SUNFLOWEREdible oil with goodorganoleptic andnutritional characteristics.Development of specialsunflowers. Secondoilseed planted inArgentina, and wasdisplaced to marginalareas and adapts tomixed systems.
SOYBEANSThe seeds are used in human and animal foods for the contribution ofproteins (40%), and edible oils (18-20%). Great expansion of cultivation inArgentina leading to problems associated with the domination ofsoybean production.
FLAXOil with high content (60%)of alpha-linolenic acid(precursor of metabolicchain omega 3), very goodindustrial quality andsource for obtaininghealthy foods. A crop witha history in Argentina andpossibilities of spreading.
RAPESEEDEdible oil with good nutrition, high content (10%) of alpha-linolenic acid and a good proportion of omega3/omega6.Very important around the world with potential inArgentina.

Consequences of the agriculturization and simplification of agroecosystems that have occurred in Argentina
• Reduced biodiversity.• Agroecosystems that are less stable and less resilient.• Displacement and reduction of livestock.• Increasing reliance on inputs.• Problems related to human and environmental health.• Degradation of natural resources.• Fewer farms.• Less demand for rural employment.• Reduced food security.
