A new law allows farmers to collect federal conservation payments for installing prairie strips. Researchers from Iowa State University who have studied the environmental benefits of prairie strips for the past decade advised the U.S. Department of Agriculture and influenced this decision. 

Prairie strips are small, but strategically placed, pieces of prairie planted within corn and soybean fields. The researchers found that converting just 10 percent of cropped land to prairie reduces soil loss by 95 percent, phosphorus loss in surface runoff by 70 percent, and provides a habitat for birds, pollinators, and other wildlife.

The Conservation Reserve Program (CRP), passed in 1985, pays farmers annually who remove sensitive land from production and plant species that improve environmental health and quality. The 2018 Farm Bill renewed the CRP and for the first time included prairie strips as a conservation practice that farmers can claim benefits from, beginning in fiscal year 2019.

Playboy Tortoise saves species


Kasey Dresser| January 20, 2019

In the 1960s, giant tortoises from Espanola, a part of the Galapagos Islands, were placed on the endangered species list. In efforts to save the species, Diego, a young adult tortoise was placed into a breeding program. 15 other tortoises took part in the breeding program, but no one committed more to the cause then Diego. The species now has over 2,000 tortoises, about 1,700 of which are descendants of Diego.

Diego weighs 176 pounds and when he’s fully stretched out, stands at five feet tall. Mr. Carrion noted that there are some characteristics that made Diego “special” and more attractive to the opposite sex. As the species continue to procreate, tortoises will continue to look like Diego. A process called the bottleneck effect, where a survivor’s gene dominates the gene pool. While little genetic diversity can leave the species vulnerable to diseases or changes in habitat, Dr. Linda Cayot of the Galapagos Conservancy said that “every species came from a bottleneck.”

Last week, the zoo announced that nearing the 80th year he’s been gone, they will be retiring Diego and returning him to the Espanola islands.

“He’s contributed a large percentage to the lineage that we are returning to Espanola,” Jorge Carrion, the Galapagos National Parks service director, told AFP. “There’s a feeling of happiness to have the possibility of returning that tortoise to his natural state.”

Trump administration rolls back NEPA climate change protections

Last week, the Trump administration proposed major exemptions from a 50-year-old environmental law. 

The National Environmental Protection Act (NEPA) requires federal agencies to assess the environmental impacts of proposed land management and infrastructure actions before making a decision. Under the new guidance, this assessment would only need to involve immediate, local impacts, rather than taking a broader view of the environment to consider effects like greenhouse gas emissions. 

Secretary of the Interior David L. Bernhardt added to President Trump that the application of the NEPA has “gone off the rails.” The president framed this decision as clearing up unnecessary bureaucracy in order to speed up important infrastructure projects. 

It also follows a pattern of this administration rolling back environmental protections. President Trump has weakened or removed nearly 100 environmental regulations since taking office. He has also been challenged by 70 separate lawsuits on these rollbacks, the vast majority of which have been successful

Many of the president’s environmental decisions have been aimed at helping fossil fuel industries. While his decision of the NEPA was framed in terms of highways and bridges, the policy has had the greatest impact on stalling oil and gas pipeline construction and coal leasing, which his administration has tried to push.

Minnesota legislators propose plan to promote clean electrical sources

Minnesota state legislators announced that they will introduce a bipartisan plan requiring electric utilities to prioritize clean energy sources. Republican leaders, including some who opposed a similar bill last year, have gotten behind the “Clean Energy First” bill as part of an effort to transition 70% of the state’s electricity sources away from fossil fuels over the next two decades.

The bill would require electric companies to use clean energy sources when building or replacing power plants. Exceptions are allowed for when clean energy can be proven to be unaffordable, or when a renewable energy source alone or in cooperation with other clean energy sources can’t meet the expected need. The bill classifies nuclear, solar, wind, hydropower, carbon sequestration, and municipal solid waste as clean energy sources.

House Democrats and Governor Tim Walz have pushed for an even more ambitious plan, to move the state’s electric sector to 100% renewable energy by 2050. Senator David Osmek, the Republican chair of the Senate Energy and Utilities Committee, has called that plan a “non-starter,” but has gotten behind the “Clean Energy First” plan. 

The Committee will hold hearings on the plan in Rochester on Jan. 15, and Minnetrista on Jan. 22.

2019 was Iowa’s 12th wettest year on record, with an average of 41.49 inches of rainfall across the state, according to the state Department of Natural Resources. Rainfall in May, September and October was especially high, while the summer months experienced below average rainfall.

The two-year 2018/2019 period was the wettest on record, with 19 more inches of precipitation than average. Stream flows were above normal all 2019 following heavy snow in the winter months. The rainy spring and fall seasons are indicative of projected climate change models for the region.

2019 temperatures in Iowa were cooler than average, however, by 1.2 degrees Fahrenheit. During the January “Polar Vortex,”one station in Emmet County recorded a -59 degree windchill. Summer was slightly cooler than average, though July and September were warm, andChristmas week broke record temperature highs.


Iowa schools exploring meat alternatives

Schools in Benton County, Iowa experimented with plant-based meat alternatives on Wednesday. The meat production industry produces the majority of agricultural greenhouse gas emissions, and scientists have said that cutting back on meat consumption is the single biggest way an individual can reduce their environmental impact.

A 2018 study found that 83% of all farmland is used for livestock, while animal products make up only 18% of total calories. Beef is one of the worst contributors to greenhouse gas emissions, releasing 105 kg for every 100 g of protein. In contrast, tofu produces less than 3.5 kg for the same amount of protein. 

The plant-based initiative is a part of Vinton-Shellsburg High School’s Farm to School program, along with the Green Iowa Americorps effort to promote sustainable schools. Green Iowa Energy Efficiency Coordinator noted that opposing meat was not likely to be a popular stance in Iowa. However, limiting the meat in one’s diet can make a difference. 

The program is focused on promoting student health, as Iowa ranks 13th out of all the states in childhood obesity. Nutritionists have repeatedly found plant-based diets to be the healthiest options, while red and processed meats have been linked to increased risk of heart disease and type 2 diabetes. 

A hotter, drier summer has worsened fire season in Australia

Though the new year has begun with relatively mild temperatures in Iowa, on the other side of the world, Australia is experiencing an unusually warm summer, leading to deadly fires in the southern part of the continent. The fires escalated over the weekend, as parts of the country hit record high-temperatures of 120 degrees Fahrenheit. 

2019 saw Australia’s driest spring on record. The dry season contributed to warmer days and cooler nights, as cloud cover and soil moisture, both of which serve as moderating factors. The dry, warm and windy conditions have led to bigger fires spreading in multiple directions. 

According to the Australian Bureau of Meteorology, the dry conditions are due in part to an air circulation pattern known as the Indian Ocean Dipole, or IOD. When the IOD is in its positive phase, it leads to cooler waters and lower precipitation in Australia. The IOD has been in this positive position for two years in a row, making conditions even drier. This back-to-back positive is unusual, but likely to occur more often going forward as a result of climate change. 

So far, the blazes have burned 12 million acres, an area larger than Switzerland, and claimed 24 lives. Thousands have been evacuated, and the Australian military has been deployed to help in the firefighting efforts.
