Cost of Farm Runoff Not To Be Overlooked

None of us would argue that efficiencies in agriculture — reducing costs to raise and harvest crops, and feed animals, for starters — have had a monumental and often very positive impact for consumers. Long story short: people need to be fed and, with a global strain of 6.5 billion, agriculture has come up with solid solutions for feeding the masses.

But producing efficiently is but one piece of the global agricultural puzzle. Another just as important component is conserving efficiently.

Lake Erie off the coast of Ohio

According to recent information from the USA chapter of the Union Of Concerned Scientists, the nationwide cost of farm runoff is hefty:

Water pollution from fertilizer runoff contaminates downstream drinking water supplies, requiring costly cleanup measures with an annual price tag of nearly $2 billion.

I would argue that this estimate is too low. A recent article in the Minneapolis Star-Tribune notes that the State of Ohio alone has received millions in aid to treat harmful algae bloom (HAB) activity and other agriculture pollution issues largely affecting Lake Erie.

The Great Lakes Restoration Initiative has spent millions on cleaning up beaches and restoring wetlands that filter pollutants along the lake shore. In all, Ohio has received just over $200 million in federal funding from the program since 2011.

While funding and incentives to improve land management from Federal and State government sources exist — through a variety of sources, like the US Department of Agriculture — to participate requires considerable effort, including an involved application process, on the part of farmers. If the financial incentive to implement better practices does not meet or exceed a crop-and-harvest approach, it is likely that only the most motivated (see environmentally friendly) farmers will apply.

What is needed is a strategy that rewards the farmers most economically challenged, or least concerned, to make permanent improvements to their land management practices. Depending on their location, these are the farms contributing most densely to HABs — farms which, within reason, are not necessarily of a particular size — that must be targeted for any real conservation impact to be realized.

 

Springtime = Farm Runoff Time

As Spring soon rolls into the Midwest, the ugly reality of melting snow across hundreds of thousands of manure fertilized fields again manifests. And the picture is not pretty.

In recent years Lake Erie has experienced Harmful Algae Blooms (HABs) larger than the size of New York City. Most of this pollution — which comes in the form of phosphorus — empties into the Western Ohio part of the Lake via the Maumee River basin.

Since the  Cuyahoga River Basin contains over 15%, or nearly 2,000,000 people, of the State of Ohio’s population, it is popular to contend that these cities are responsible for the pollution. But this argument falls flat, according to a report from LakeErieAlgae.com.

The differences in how heavy spring rainfalls affect phosphorus loads in two watersheds – the Maumee and the Cuyahoga – show the different impacts of non-point sources (like the primarily agricultural lands in the Maumee River basin) and point sources (like the urban and industrial lands in the Cuyahoga River basin, which houses nearly 15% of Ohio’s population). Both watersheds occasionally have combined sewer overflows (CSOs), but research suggests these volumes pale in comparison to the river volume during storms.

In short, the Maume River, flowing through the mostly agricultural Maumee River Basin, is responsible for the vast majority of the phosphorus pouring into Lake Erie. And this phosphorus is the key trigger to HABs.

Watch closely as Spring 2017 approaches. HABs will result no matter what but, should heavy rains accompany the annual melting of snow, record HABs will again be reported across not just Lake Erie, but throughout the USA and beyond.

This excellent report from The National Wildlife Federation (NWF) offers numerous touch points on how to curb HABs, like the below:

  • We need increased actions to address nonpoint source pollution, in particular agricultural runoff. This includes increased targeting of Farm Bill and other programs to priority areas, and continuing research to identify key nutrient source areas.

Summer HABs will be explained in no small part by Spring meltdown and precipitation levels.

The connection is indisputable.

Inauguration, Infrastructure, Promises … and Clean Water

The inauguration of United States’ 45th President Donald J. Trump represents America’s ceremonial yet very real transfer of presidential power. In his address, President Trump promises among things to “never let (Americans) down.” His vow to bring back jobs, and rebuild infrastructure by improving roads, schools, bridges, airports, etc., is a bold one.

Donald Trump Inauguration

Although it is likely few Americans expect a shiny new country four years from now, the success of President Trump’s administration will be measured by bricks and mortar — upgraded and replaced from the labor of American hands. Should he fall flat on this great promise, clearly he will have let down US citizens.

It is not necessarily alarming that nowhere in President Trump’s speech was there the mention of clean water. Surface and ground water problems are often local, and governing clean water issues is generally left to area, regional, and state government.

But this year, when Toledo, OH (again) cannot tap drinking water; when Waukesha County, WI, (again) cries out for freshwater from Lake Michigan; when a proliferation of lakes and rivers all across the USA (again) fill with Harmful Algae Blooms (HABs) — threatening the health and well-being of tens of millions of Americans — the United States’ freshwater crisis will (again) emerge. The crisis already exists in pockets throughout the USA and, in President Trump’s tenure, it will likely become a highly visible federal government priority.

As this priority applies to surface water — which is impacted differently than groundwater — collaborating with agriculture will be paramount. Because, above all other industries (and by a wide margin), according to information from GRACE Communications Foundation, agriculture is the number one contributor to surface water pollution.

Best practices for decreasing surface water pollution from agriculture exist — and have been documented in Clean Water Warrior many times.

Rewarding farmers, long-term and permanently, for implementing best practices is key to in any meaningful way cleaning up surface water. Farmers must be willing to accept the reality that economic and land-management changes to their operations are necessary, and must now be implemented. Government, working with nimble non-profits like Clean Water Warrior, must be swift in providing resources to assist and reward farmers making these best-practice changes.

It will be an interesting four years. President Trump – the stage is yours.

 

 

 

 

Clean Water New Year’s Resolutions

The year 2017 rings in with many of us, all over the planet, resolving to do better.

  • Get in better shape.
  • Become more skilled and a better co-worker on the job.
  • Be more altruistic and a better member of society.

As a planet, becoming better stewards of clean water can be added to this list. But what can we do?

The City of Bellevue, WA, offers terrific suggestions to its residents for reducing contamination to surface water. Pollution from cities like Bellevue is called point pollution, as described below in an excerpt from the Environment Protection Agency (EPA) site:

The term “point source” means any discernible, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, or vessel or other floating craft, from which pollutants are or may be discharged.

Importantly, point pollution does not include agricultural storm water discharges and return flows from irrigated agriculture. Otherwise known as farm runoff.

Managing Animal Grazing Helps Prevent Toxic Water Runoff.

Point pollution, often to the surprise of many, also does not account for the vast majority of surface water pollution across the USA and elsewhere. That responsibility lies with agriculture, and farm runoff.

In this 2014 Scientific American article, Lake Erie Basin farm fields are cited as being responsible for at least 60% of the phosphorus now reaching Lake Erie. Phosphorus is the key nutrient feeding the epic algae blooms occurring annually in the lake. This 60% figure is tossed around regularly — in many places the percentage is as high as 80% — wherever and whenever agriculture, algae blooms and phosphorus are discussed.

So, in addition to what Bellevue, WA suggests we as individuals can do to foster clean surface water, let’s encourage agriculture to resolve to follow some guidelines for the new year as well. Priority areas noted below, and the specific practices recommended, come from the Environmental Protection Agency’s guide: National Management Measures to Control Non-point Source Pollution from Agriculture.

Conservation Tillage – leaving crop residue (plant materials from past harvests) on the soil surface reduces runoff and soil erosion, conserves soil moisture, helps keep nutrients and pesticides on the field, and improves soil, water, and air quality;
Crop Nutrient Management – fully managing and accounting for all nutrient inputs helps ensure nutrients are available to meet crop needs while reducing nutrient movements off fields. It also helps prevent excessive buildup in soils and helps protect air quality;
Pest Management – varied methods for keeping insects, weeds, disease, and other pests below economically harmful levels while protecting soil, water, and air quality;
Conservation Buffers – from simple grassed waterways to riparian areas, buffers provide an additional barrier of protection by capturing potential pollutants that might otherwise move into surface waters.
Strategic Irrigation Water Management – reducing non-point source pollution of ground and surface waters caused by irrigation systems;
Grazing Management – minimizing the water quality impacts of grazing and browsing activities on pasture and range lands;
Animal Feeding Operations (AFOs) Management – minimizing impacts of animal feeding operations and waste discharges through runoff controls, waste storage, waste utilization, and nutrient management;
Erosion and Sediment Control – conserving soil and reducing the mass of sediment reaching a water body, protecting both agricultural land and water quality and habitat.

The new year has arrived. Here’s hoping it will be a good one for everyone — starting with the water we share.
