Towards Sustainable Agriculture: Assessing Scenarios for the Dudley Smith Farm
- 1. Towards Sustainable Agriculture: The Dudley Smith Farm “Revision – New” Thesis Presentation Timothy Marten BLA Funded by: Dudley Smith Initiative
- 2. World, we have a problem… Impacts of Industrial Agriculture www.treehugger.com Impacts of Natural Systems •Hypoxia Greenpeace •Soil erosion •Chemical dependency & pollution •Generation of greenhouse gases •Unmanageable and polluting mountains of waste Impacts of Economic Systems •Profits end up in agri-business giants, including fertilizer and pesticide manufacturers •No accounting for environmental costs •Lower rural living standards Impacts of Social Systems •Public Health i.e. Endocrine disruption from pesticides Greenpeace •Rural Exodus •Dying rural communities •Consolidation of powers and means of production
- 3. Agriculture at a Crossroads Can we achieve sustainability under our current Industrial paradigms or is a paradigm shift needed? Agriculture must be rebalanced to support our social and economic systems while constraining to ecological limits and functioning as a sustainable agroecosystem. Nevertheless, how can sustainable agroecosystem be developed and assessed? A new paradigm for Midwestern agriculture that balances social support systems, economic viability and environmental limits and preservation is needed.
- 4. Fundamental Sustainability Goals The DSF & Project Aim 1. Produces all energy needed for farm operations, hauling, and processing of biofuels or fertilizers. 2. Sequester more carbon then it produced and off set all NOx and Methane Emissions 3. Produces all feeds needed for animal production 4. Import no chemical nutrients 5. Reduce nitrate runoff by 90% from existing conditions and capture at least 50% of nitrate originating from the farm 6. Be economically viable “understand the interactions among the components of the agricultural and community system, including its natural resources, economic base and social elements, to make agriculture sustainable over the long term.”
- 6. Process/Methodology What are the potential futures and the implications of these futures within bioregion ? How will various scenarios affect the sustainability of the DSF a bioregion? What are the key metrics to measure scenarios/possible futures by? How would the Dudley Smith Farm, as an example, look under various scenarios?
