Making change is the work of many hands

The large figure below is a product of the Prairie Rivers Network,  an organization of Illinois citizens founded in 1967 to block the plans of the Army Corp of Engineers to build an ill-advised reservoir near Decatur, Illinois. Over years of advocating for environmental causes the organization grew and became part of the Coalition of American Rivers, dedicated to resisting other Corps of Engineers projects throughout the Midwest. Under the leadership of John Marlin, the first paid Executive Director (1973-1983), the Coalition drew people from varied political and social backgrounds to protect rivers from federal water projects that threatened most of the nation’s rivers in the 1960s and ’70s.

Their figure is loaded with information that calls us to pay attention. Let’s start with the statement about nutrient pollution.  Illinois, like all the other midwest prairie states, is heavily into industrial agriculture. Corn and soybean crops dominate the landscape. Which of the crops dominates in a given year is determined by many factors; predominantly weather, market forces, the trade wars, government subsidies, crop insurance.  In any given year, most of the available land is planted in one of the two crops. The processes of plowing, planting, irrigating, fertilizing and keeping the bugs and weeds under control result in enormous runoffs, that flow into small streams, then flow into larger ones, eventually empty into the big rivers and thence into the Gulf of Mexico. That water, further enriched with the runoffs from animal feedlots, is seriously polluted. All along its long journey It infiltrates local aquifers and surface sources for municipal water systems, kills wildlife and--year by year--depletes the originally rich, loamy soil of its organic matter. When it arrives in the Gulf, it creates a huge nutrient-rich dead zone.

Very little of the corn and soybean grown on those Illinois fields goes directly into the food chain. A lot of it goes to feed animals that are converting it into manure and methane gas,  and another large fraction is converted into bioethanol, a transportation fuel. The entire system could not be more cleverly designed to convert enormous quantities of fossil fuels into greenhouse gases, notably  carbon dioxide and methane.  If we were to set out to poison the planet, we’d build something like present-day industrial agriculture as a prime element. 

 Agriculture is estimated to produce somewhere around 14 to 18 percent of greenhouse gas emissions globally. That makes it the single largest contributor to global warming.  Even more concerning is the fact that nations around the world seem to be eagerly looking to emulate US agricultural practices. We have a  great challenge before us: to feed a growing global population. It's become evident, though, that we’re going about it in the wrong ways.  Fortunately, there are solutions to the problem.  One of them is indicated at the top right of the figure. Regenerative agriculture practices can reverse the path we’re on. The problem is, what society should do as a matter of great urgency  isn’t consistent with the business plans of corporate agriculture. It will take a lot of hard politicking and good government to make progress in shifting from the wasteful, poisonous farming methods of today to no-till farming, use of cover crops, and more thoughtful management of water systems. 

Cover crops are a big factor in making the system work.  As the large figure at the top shows, there is movement; in Illinois, more than 700,000 acres devoted to corn and soybeans are utilizing cover crops.  Ah, but it’s going too slowly!  We need to get to about 18 million acres. Data from an Illinois EPA analysis indicates that at the current rate of adoption, we’re 200 to 500 years away from where we need to be. Time is running out!  Similar states of affairs are found in the other midwestern states, even in the face of wonderful examples of what can be achieved using regenerative agriculture.  Gabe Brown’s Youtube video talk on his experiences in North Dakota provides an inspiring example of how effective regenerative agriculture can be.  

Five years ago, as part of the Paris Accords, a $100 billion multilateral Green Climate Fund was established within the UN Framework Convention on Climate Change. The United States committed $3 billion to the initial creation but has to date paid in only $1 billion.  With the Trump administration moving to withdraw the US from the Paris Agreement, there is no prospect that the US will pay any of its shortfall, let alone contribute more funds to the cash-strapped fund. These monies are intended to assist with climate adaptation in poor countries.  The goal for the Green Climate Fund was $100 billion per year.  At this point, commitments are falling far short of what was promised. Still, nations are responding, and one can hope that over time the urgency of the situation will impress itself.  

It will take a great deal of hard work and determination to buck the established ways of doing things, and brilliant new science and engineering to create a way forward.  Here are two examples of promising new technologies that could play a role:

• The company Indigo Ag was founded to develop technologies around using microbes living within a plant to help plants protect themselves from insects, disease, and drought. That description does not do justice, however, to the range of the company's activities, which stretch across virtually all aspects of the agricultural enterprise. They are off to a fast start and have operations running in many parts of the globe.  The CNBC interview with CEO David Perry gives an idea of the breadth of their vision.  They are moving toward a radical disruption of modern agricultural practices for producing the major grains that feed the world.

• The Bill and Melinda Gates Foundation recently announced additional support for a project at the University of Illinois Urbana-Champaign entitled Realizing Increased Photosynthetic Efficiency (RIPE). A key aim of the RIPE project is to provide farmers, particularly those in some of the world’s poorest countries, with seed that will yield substantially more without requiring more inputs. Scientists working in RIPE take advantage of a long history of scientific research, coupled with the latest discoveries in plant biology, to tweak photosynthesis to produce improvements. According to the project director, Professor Stephen Long, seen here with co-Director Donald Ort,
  

  

  “Our models predict that by combining several strategies we could achieve a 50 percent yield increase, which will go a long way to meeting the demands of this century.”  The RIPE project has a long way to go before it can be transferred to food crops, tested for safety and widely deployed on a global scale.  The scientists are all too well aware that they are racing against the increasing effects of climate change. Government needs to increase its support of this and other promising research efforts.  

It's inspiring to see that there's a kind of two-pronged system at work. The Prairie Rivers Network advocates at the local level for sustainable agricultural practices, lobbying legislators, educating in the school systems and in the public sphere generally about what is at stake, and what individuals can do to build support for effective legislation. Those folks are living in the same community as the researchers at the University of Illinois engaged in world-class research with the aim of finding technological solutions.  And the people at Indigo Ag are engaged in developing commercially successful answers that will be applicable globally.

So what can you and I do?  We can read and learn; use the Internet to ask questions and find answers; find the phone numbers and e-mail addresses of state and federal legislators and make calls; lobby regulatory agencies when we see examples of counter-productive cancellation or relaxation of effective rules ( In this regards, try following Huffpost Agriculture for a daily feed that can be interesting and surprising).  What we mustn't do is give up, or get too busy with other things.
