Why Are We Here? Managing Water, Harvesting Results America’s Ag Water Management Summit Tom Christensen Regional Conservationist USDA Natural Resources Conservation Service October 11 – 12, 2011
Why Are We Here? Increase voluntary adoption of drainage water management as part of a conservation system How? Through a better understanding of: • Lessons learned • Current situation • Barriers • Limitations • Opportunities • Assessments Needed
Goals of Summit • Understand drainage water management and its role in a conservation systems approach • Provide exposure to current and evolving technologies and innovations • Identify policy and programmatic barriers and opportunities • Foster commitment to action among partners, including outreach and education
What Have We Learned? • Sound science must be the foundation for conservation. • Conservation works and can improve the economic bottom line. • Watershed and site-specific conservation planning are needed to aid decision-making. • Targeting critical areas improveseffectiveness and efficiency. • Technical assistance is criticalto planning, implementation,and follow-up. • Effective adaptive management,after implementation, is vital. • Leadership and partnershipsmust be effective and sustainable.
Measuring the Environmental Benefits of Conservation:Conservation Effects Assessment Project (CEAP) • CEAP is a multi-agency effort to quantify the environmental effects of conservation practices and programs and develop the science base for managing the agricultural landscape for environmental quality. • Project findings are used to guide USDA conservation policy and program development and help conservationists, farmers and ranchers make more informed conservation decisions.
River Basin CEAP Reports Release Schedule* • Upper Mississippi: Released in June 2010 • Chesapeake Bay: Released in February 2011 • Great Lakes: Release is eminent • Ohio-Tennessee: In review; followed by a 30-day review period; then approximately 14 days addressing comments; then release per the Department. • Missouri: Draft completed September 21, 2011 (then follows the same release procedure as the Ohio-Tennessee.) • Arkansas-White-Red: Draft completed October 7, 2011 • Lower Mississippi: Draft completed October 28, 2011 • Northwest : All three are on schedule to be released by January 2012. • South Atlantic/Gulf, Northeast, Texas Gulf, and Pacific: All three are on schedule to be released by January 2012 • * This schedule is subject to change due to two forces: • Sometimes reviewers will find items they would like to be considered and NRCS explores them prior to release of a final public document. • The Department determines the timing of the release.
What CEAP Reveals in the Upper Mississippi River Basin Conservation Practices Work Compared to no conservation practices: • Sediment loss reduced by 69% • Total phosphorous loss reduced by 49% • Total nitrogen loss reduced by 18% • Pesticide risks to human health reduced by 48% Comprehensive Planning is Needed • Surface nitrogen losses reduced by 46% BUT subsurface losses are reduced by only 5% • Without nutrient management practices, erosion control practices can increase subsurface nitrogen losses by re-routing surface water to subsurface flow pathways Significant Progress Made in Reducing Erosion and Sedimentation • 45% of the cropland and 72% of highly erodible land has structural practices • Edge of field sediment loss reduced by 69% • In-stream sediment reduced by 37%
NRCS Landscape Initiatives • Initiatives have national or regional significance and focus on critical resource concerns at the landscape level • Build on existing locally-led efforts and are partnership driven • Dedicated funding to accelerate implementation • Science-based • Assessment of performance and environmental outcomes
NRCS Expectations for ADWM • Not about draining new acres • Focus is managing drainage water for improved environmental outcomes and sustaining crop production • Use a conservation systems approach—ADWM with nutrient management, conservation tillage, crop rotations, cover crops, etc. • Consideration must be given to watershed/landscape context—downstream flow, flooding, groundwater • Partnerships and collaboration will be essential—research, demonstration, technical and financial assistance, assessment and evaluation, etc.
Water Quality and a Conservation Systems Approach • A conservation systems approach implements multiple practices and management techniques that work together to address water quality nutrient issues at the edge of farm fields • Practices • Core • Supporting

Nutrients: Avoiding, Controlling, Trapping (ACT) Avoiding • Avoiding • Nutrient management • Rate, Timing, Form, Method • Controlling • Residue and tillage management • Drainage water • management • Trapping • Buffers • Wetlands designed for nutrient removal ACT Controlling Trapping
Management of Ag Drainage WaterNRCS Ad Hoc Action Team(Phase I)
Management of Ag Drainage WaterNRCS Action Team(Phase II) Charge: • Evaluate Phase I recommendations for feasibility and priority • Develop and implement NRCS Action Plan with partner input and involvement • Help formulate and conduct National Summit • Stimulate innovation and creativity • Evaluate progress, performance and outcomes
Partner Input • Periodic meetings/conference calls on draft NRCS Action Plan and issues/opportunities • March 23, 2011 • June 15, 2011 • October 11-12, 2011 (National Summit) • Website to share materials • CEAP Results—Upper Mississippi and ADWM Scenario • Training Opportunities—MRBI Focus
Next Steps • Finalize and implement NRCS Action Plan • Supported by State-level action plans • Outreach to ag community • Local, state and national • Education and training of technical providers • Foster and promote innovation • Assess/evaluate progress and “practice adaptive nutrient management” • Keep conservation systems approach at the forefront
Partnership OpportunitiesSustainable, environmentally friendly, safe food production • By 2050 there will be 2.4 billion more people to feed. • 2007 National Resources Inventory (NRI) tells us that U. S. cropland acreage dropped by 63 million acres between 1982 and 2007. • From 420 million acres to 357 million acres • To close the gap between current food production and future food demand, food output will need to increase by 70 percent over the next 4 decades.
“We cannot depend on windshield surveys and office planning to carry out a job of the complexity and magnitude of safeguarding our farmland and controlling floods.” - Hugh Hammond Bennett
