Wetlands and Flood Mitigation: The 10 Percent Solution

Following the Great Flood of 1993, an official report called for more research to find ways to prevent flood devastation, apparently unaware the problem had been mostly solved, conceptually over a decade earlier. But taking action through the implementation of a national wetland restoration program has faced intractable political and economic obstacles.

Keep Your Shirt On, Save Some Coral?

This is not great news, especially for those of us who like to be out in the sun but get really bad sunburns. As reported by Nature and Scientific American, Hawaii state senator Will Espero has introduced a bill to ban sunscreens containing oxybenzone and octinoxate, two chemicals that may pose risks to us, such as endocrine disruption, as well as to coral. The Environmental Working Group maintains lists of …

Federal GIS Data in Jeopardy

How safe is Federal GIS data? Thursday, I ran across this article on a Reddit GIS forum and felt troubled by it. What is the motivation behind this legislation, House Bill HR482 and Senate Bill S103? From Section 3 of each bill: “Notwithstanding any other provision of law, no Federal funds may be used to design, build, maintain, utilize, or provide access to a Federal database of geospatial information on …

Maine Shake Map Using Surficial Geology and Crowd-Source Responses

Researchers in Maine (Marvinney and Glover 2015) have created a clever earthquake risk shake map using readily available surficial geology maps and online responses from state residents. Did you feel it? That is the name of a USGS Earthquake Hazards Program interactive website that “collects information from people who felt an earthquake and creates maps that show what people experienced and the extent of damage.” I first became interested in …

Rejected Export Corn Prompts Class Action Suit

Updated 16 November 2016 When it’s assumed that food grown using modern high-tech agriculture, including GMO crops and greater reliance on chemical pesticides, is absolutely necessary to feed a growing world population, one might be tempted to question that assumption when the most populous nation in the world rejects such food. Syngenta Litigation There are some angry farmers in the U.S. who, in 2013-2014 were unable to sell their GMO …

Lake Erie Algae Blooms Correlate to June Rainfall

June precipitation appears to be positively correlated to algae blooms in Lake Erie. Looking at monthly precipitation data readily-available from Weather Underground and comparing it to the Western Lake Erie Algae Bloom Severity Index, I was surprised by the strength of the correlation (0.6, 0.85 with an “outlier” removed). June precipitation was the only month to correlate to the Severity Index in my data set and I was surprised that …

Lake Erie Watershed Soil Phosphorus Study Shows Glyphosate Link

As reported recently by Laura Barrera in the┬ámagazine No-Till Farmer, a study led by Ohio Northern University chemistry professor Christopher Spiese links the popular herbicide glyphosate to dissolved reactive phosphorus (DRP) desorption in soils. Mobilization and runoff of phosphorus to streams and lakes is associated with toxic algae blooms in Lake Erie and the Gulf of Mexico Dead Zone. For decades, soil scientists have understood phosphorus to form low-solubility compounds …

Half of U.S. Corn Crop Now Goes to Ethanol

Farming has always been about energy. We eat food for energy our bodies need to survive. But now American farming is increasingly about filling gas tanks as well as bellies. At a typical gas station found along an interstate highway, one can fill up on gasoline blended with 10% ethanol made from corn, pay for it using a plastic card, perhaps made from corn, pull around the side of the …

Herbicides, Critical Source Areas, and Vegetated Buffers

Waging Chemical Warfare on Weeds Last fall, while on one of my country road walking routes, I noticed an advanced infestation of marestail (Conyza canadensis) in a soybean field. Evidently, this weed, and others, is becoming herbicide-resistant. A new agricultural herbicide called Acuron (link goes to manufacturer’s website) is on the market, and in some fields. Acuron has been developed in response to “superweeds” that have grown resistant to glyphosate, …
