26 Diversification of Agricultural Landscape Systems Chippewa River Wells Creek

27 Cultivated Land Grassland Deciduous Forest Urban 80% in cultivation and includes a portion of Montevideo Catchment size: 17,994 ha Chippewa River Land Use

28 Four Scenarios D Managed year-round vegetative cover Cover crops, increased managed grazing, prairie restoration, 90 m buffers 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

31 Green Lands, Blue Waters A Vision and Roadmap for the Next Generation of Agricultural Systems

32 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.

33 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.

34 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

35 Benefits to Bird Populations Tilled row crops > 18 species Tilled row crops, herbaceous fencerow, grass waterway, alfalfa and pasture > 25 species Tilled row crops, herbaceous fencerow, grass waterway, pasture, alfalfa, and marsh > 52 species Tilled row crops, herbaceous and wooded fencerows, grass waterway, pasture, alfalfa, marsh, and farmstead shelterbelt > 93 species Best, L. et al A Review and synthesis of Habitat Use by Breeding Birds in Agricultural Landscapes of Iowa. The American Midland Naturalist, 134:1 Bird responses to habitat changes (sightings per 160 acres)

36 Grazing Systems Perennial ryegrass Winter hardiness, Seed production, Rotational grazing Illinois bundleflower and other native legumes Mixed warm season grass- rotational grazing systems

37 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

38 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

39 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

40 Oil Seed Crops Perennial flax, Linum sp. Perennial sunflower, Helianthus sp.

41 Wetland Restoration Willow, Salix sp. Nitrogen harvesting, energy, water retention Native wetland species Unique industrial chemicals, wildlife habitat-hunting

42 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

43 Advantages to Production Agriculture Improve environmental performance Improve economic diversity/profitability Keep working lands working Adopt a non-regulatory, long term strategy

44 Strategy 1 Involve diverse stakeholders –Audubon Society, Upper Mississippi Basin Initiative** –Illinois Stewardship Alliance** –Institute for Agriculture and Trade Policy** –The Land Institute** –Land Stewardship Project** –Minnesota Farm Bureau –Mississippi River Basin Alliance** –National/Minnesota Farmers Union –The Nature Conservancy, Upper Mississippi Basin Project** –Minnesota Pollution Control Agency –US Environmental Protection Agency –USDA/US Forest Service

45 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 Missouri –University of Wisconsin**

46 Strategy 3: Organize at the Watershed, State & Basin Levels Watershed Learning Groups (Kellogg Foundation) –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

47 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

48 Strategy 6: Imbed in Mainstream Thought Strategy 7: Rely on Voluntary Approaches

49 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 and focus on continuous living cover systems Identify and promote supporting policy changes

50 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

51 Budget On the scale of $105 million over ten years
