Conservation Program Effectiveness Supported in New NEMWI Research Reports Focusing on Eight Watersheds in Four States in the Upper Mississippi.

A new research report on conservation program effectiveness released in September by the Northeast-Midwest Institute provides strong scientific support for the effectiveness of conservation programs, especially the conservation practice of tillage with crop cover, in protecting agricultural land and improving water quality in the Upper Mississippi River Basin.  The high level of effectiveness of conservation was confirmed both with historical conditions and with modeled climate change. 

Separate research reports document the effectiveness of conservation practices for each of the watersheds studied, including the Upper Sangamon and Vermilion watersheds in Illinois, the Boone and Upper Wapsipinicon watersheds in Iowa, the Cottonwood and Watonwan watersheds in Minnesota, and the Sugar and Trempeleau watersheds in Wisconsin.

The new research reports support policy-making that continues and expands conservation programs, including federal programs to incentivize farmers to implement effective conservation programs.  The findings for each of eight watersheds document that policy options promoting conservation tillage with crop cover such as rye grass enhance agricultural productivity in upstream areas and reduce pollution in downstream freshwater systems.

Unique in the new research is that it employs a watershed-specific approach that selected eight watersheds - two in each of four states, the states of Illinois, Iowa, Minnesota, and Wisconsin - evaluating the effectiveness of alternate conservation practices employed by farmers. Each of the eight watersheds studied is in a different Congressional Districts in these four states.

Significant findings in this new watershed conservation research include:
  • Crop cover with rye was found to be the most effective conservation practice in reducing nutrient losses in each of the eight watersheds.
     
  • Conservation effectiveness ranged from 6 percent to 43 percent in terms of the reduction in nitrogen loss, and from 7 percent to 31 percent in terms of the reduction in phosphorous loss.
     
  • In modeling the impact of climate change, which in seven of the eight watersheds is predicted to reduce precipitation and therefore water flow in the range of 9 percent to 70 percent, the reduced water flow resulted in a reduction in nutrient leaching in these seven watersheds and improved efficiency of conservation practices in reducing nutrient loss in the face of climate change.
According to the watershed conservation research report for one of the watersheds studied, the Cottonwood watershed in Minnesota, "conservation tillage practices were effective in reducing soil erosion and limiting nutrient loss from the Cottonwood watershed...The most effective intervention to reduce soil erosion and nutrient losses was the conservation tillage with crop cover, both in the historical climate and climate change scenarios."  The study showed that conservation tillage with crop cover in the Cottonwood watershed reduces the long-term average annual sediment yield by 5-10 percent, total nitrogen loss by 13-26 percent, and total phosphorus loss by 10-20 percent at the watershed outlet compared to continuing the current farmers' (baseline) tillage practice.

In releasing the watershed conservation research report, Northeast-Midwest Institute President and CEO Dr. Michael J. Goff stated "It is imperative to make the strongest case possible for the effectiveness of watershed conservation, because encouraging and incentivizing farmers to utilize the most effective conservation practices both protects their land and protects water quality.  This study provides strong evidence yet again that conservation practices work, a message which we hope Congressmen and Senators hear and respond to with future appropriations and policy-making."

Conducting the hydrological data analysis for the new research report was Dr. Raghaven Srinivasan, Professor of Ecology and Conservation Biology at Texas A&M University, with policy analysis and preparation of the study reports by Dr. Yihun Dile, also of Texas A&M University.

This new watershed conservation effectiveness research report, and the previous research report on this topic, were funded by the Walton Family Foundation's environmental program.

Midwest Climate Summit Hosts First Think Tank Session
 
The Midwest Climate Summit last Friday, October 2 hosted its first Think Tank session on a collaborative response to the current climate crisis in the midwest region. Equity was the session's major theme, with Dr. Robert D. Bullard emphasizing that "addressing equity is a prerequisite to achieving climate-resilient communities (because) when we provide the greatest protection for the most vulnerable, we provide protection for us all." He noted that the inclusion of marginalized communities in climate conversations is essential because they suffer systemically and disproportionately from climate change.
 
The purpose of the Think Tank sessions is to inform educational institutions, local government partners, and business community partners in order to encourage climate action. The Midwest Climate Summit wants to expand knowledge on the importance of lowering emissions, creating a green economy, and ensuring an easy transition for all Midwest states to become adaptable.
 
Last week's event, which was conducted virtually, was the first in a two-part summit series - the first in fall of 2020 and the second in spring of 2021 -- to help build support and momentum for climate action in the Midwest region. There will be four additional Think Tank sessions this fall -- on October 9, October 23, November 6, and November 20. Each session will feature speakers who will lead a series of workshops focused primarily on climate action, science and research, teaching and education, and outreach and engagement. The spring 2021 sessions have not been posted yet.

CR Funding for the Government through Dec. 11 Signed into Law 
The President signed a continuing resolution (CR) last week that would fund the federal government at current levels through Dec. 11 because Congress has failed to pass any of the FY 2021 appropriations bills. The CR also contains a one-year extension of both federal surface transportation programs and the federal flood insurance program, which were also set to expire at the end of September.  
While Congress has provided a short-term solution to the FY 2021 budget, it continues to consider potential relief legislation to address the COVID-19 pandemic. Before recessing for the month of October, the House passed a slimmed-down $2.2 trillion version of the "Heroes Act." The House had originally passed a much larger stimulus bill earlier in the summer. However, House and Senate Republicans continue to push against the House bill calling for an even more limited stimulus bill. 
The House has also recessed for October and the first half of November, but the Chamber's leadership has notified members that they could be called back for a vote if an agreement on a stimulus package can be reached. Additionally, because of recent positive COVID-19 tests for several Republican Senators, Majority Leader Mitch McConnell (KY) has stated that the Senate will be meeting in pro forma sessions for the next two weeks and that previously scheduled floor activities will be rescheduled until after October 19th. However, the Majority Leader also said that the Senate Judiciary Committee will still convene on October 12th to begin the confirmation hearings for Judge Amy Coney Barrett's nomination to the Supreme Court.
