Diversification of Agricultural Landscape Systems Chippewa River Wells Creek
Chippewa River Land Use 80% in cultivation and includes a portion of Montevideo Cultivated Land Grassland Deciduous Forest Urban Catchment size: 17,994 ha
Four Scenarios A Extension of current trends • Increased field size, focus on annual crop production B Adoption of best management practices • Shift to conservation tillage, use recommended nutrient application rates,30 m riparian buffers C Expand diversity • Five year crop rotation, more grazing • Wetland restoration • D Managed year-round vegetative cover • • Cover crops, increased managed grazing, prairie restoration, 90 m buffers

Green Lands, Blue Waters A Vision and Roadmap for the Next Generation of Agricultural Systems
Initiative Vision To improve water quality in the Mississippi River Basin, increase economic options and profitability for farmers, improve wildlife habitat, reduce flooding potential, strengthen vitality and quality of life of rural communities, and enhance human health.
Initiative Mission To support development of and transition to a new generation of agricultural systems in the Mississippi River Basin that integrate more perennial plants and other continuous living cover into the agricultural landscape.
Objectives: Develop and promote profitable enterprises • Build Capacity of stakeholders regarding continuous living cover systems and water quality; • Significantly expand the knowledge base regarding continuous living cover systems and their impacts and potential • Coordinate and build on related new and existing activities • Heighten visibility and increase financial support of andfocus on continuous living cover systems • Identify and promote supporting policy changes
Potential Ecosystem Services Provided by Perennial Cropping Systems Nutrient Cycling, Flood Management, Natural Pest Management, Soil Health,Wildlife Diversity, Water Quality, Erosion Control, Carbon Management, Climate Mediation
Grazing Systems • Perennial ryegrass Winter hardiness, Seed production, Rotational grazing • Illinois bundleflower and other native legumes Mixed warm season grass-rotational grazing systems
Biomass Energy • Willows, Salix sp. • Alfalfa, Medicago sativa, JoAnn Lamb USDA-ARS St. Paul • Perennial sunflower, Helianthus sp. • Perennial flax, Linum perenne • Native legumes, False indigo, Amorpha fruticosa
Trees and Shrubs • Willows, Salix sp. Decorative and energy • Hybrid popular, Populus sp. Energy and fiber • Hazelnuts, Corylus avellana x C.americana and C. cornuta Oil, confectionary, and energy
Perennial Native Legumes • 50 species preliminary evaluation Winter hardiness • 10 species more detailed studies Production and selection Feeding trials—swine Antioxidants—Food, fuel, feed and cosmetics Antimicrobial—Food, cosmetics and feed
Oil Seed Crops • Perennial flax, Linum sp. • Perennial sunflower, Helianthus sp.
Wetland Restoration • Willow, Salix sp. Nitrogen harvesting, energy, water retention • Native wetland species Unique industrial chemicals, wildlife habitat-hunting
Cover Crops • Red clover, Trifolium pratense • Winter rye, Secale cereale, Paul Porter • Brassica sp. • Alfalfa, Medicago sativa • Birdsfoot trefoil, Lotus corniculatus • Native legumes April 30, 1999
Advantages to Production Agriculture • Improve environmental performance • Improve economic diversity/profitability • Keep working lands working • Adopt a non-regulatory, long term strategy
Strategy 1 Involve diverse stakeholders • Audubon Society, Upper Mississippi Basin Initiative • Iowa Farmers Union • Illinois Stewardship Alliance • Institute for Agriculture and Trade Policy • The Land Institute • Land Stewardship Project • Minnesota Farmers Union • Mississippi River Basin Alliance • The Nature Conservancy, Upper Mississippi Basin Project • The Practical Farmers of Iowa • Trout Unlimited • Minnesota Pollution Control Agency • US Environmental Protection Agency • USDA/US Forest Service
Strategy 2:Engage land-grant institutions • The University of Illinois** • Iowa State University, including the Leopold Center for Sustainable Agriculture** • Louisiana State University • North Dakota State University ** • University of Minnesota ** • University of Wisconsin** ** indicates collaborators who have signed letters of participation
Strategy 3:Organize at the Watershed, State & Basin Levels • Watershed Learning Groups (CIG / EPA Grant Pending) • Initially focus on two watersheds/state • Develop learning groups • State Coordinating Committees (Federal Leopold) • Representatives from learning groups and the consortium • Responsible for planning, implementing and monitoring in that state • Multi-state consortium (Charter Partners &McKnight) • Land-grants, NGOs, and government agencies • Responsible for overall planning, monitoring and budget oversight
Strategy 4: Targeting a portion of the most environmentally sensitive lands will maximize the environmental benefit Strategy 5: Develop Supporting Infrastruture Market – Technical – Financial Social – Human - Policy
Strategy 6:Imbed in Mainstream Thought Strategy 7:Rely on Voluntary Approaches
Ten-Year Outcomes • Development of new crops, products, and associated markets for products of continuous living cover systems • Increased continuous living cover on the agricultural landscape in the Mississippi River Basin • Reduced N loading from agricultural production at the watershed level by 30% • Reduced number of impaired waters in the watersheds • Increased migratory waterfowl and neo-tropical songbird populations at the watershed level by 30% or more. • Shrinkage of the hypoxic zone from its 2002 level
