Gulf dead zone

Churned by hurricane, ‘dead zone’ is one-third expected size

The fish-killing "dead zone" in the Gulf of Mexico this summer is the third-smallest in 34 years of surveys, reported scientists. At 2,116 square miles, the hypoxic region is about one-third the size of the forecast of 6,700 square miles.

‘Dead zone’ in Gulf is eighth-largest on record

The fish-killing “dead zone” in the Gulf of Mexico this summer covers 6,952 square miles, midway in size between Connecticut and New Jersey, said researchers on Thursday. It is the eighth-largest dead zone in 33 years of keeping records.

Report: Biodiesel driving deforestation and host of other problems at home and abroad

An investigation by activist groups Mighty Earth and ActionAid USA challenges the notion of biodiesel as the environmentally responsible fuel of the future. Burned: Deception, Deforestation and America’s Biodiesel Policy claims that growing demand for biodiesel in the U.S. contributes to a host of problems, from deforestation in Argentina and Indonesia to algae blooms in Lake Erie and the Gulf of Mexico’s dead zone.

Iowa offers incentive to farmers who plant cover crops

Iowa, which has been embroiled in controversies over agricultural runoff and water-quality issues, has announced a novel program to give farmers who plant cover crops a $5-per-acre discount on their crop insurance over the next three years, according to the Natural Resources Defense Council.

Great Plains loses 2.5 million acres of grasslands in one year

The annual Plowprint report by the World Wildlife Fund estimates 2.5 million acres of virgin grasslands in the Great Plains were converted to cropland, or energy and urban development last year. While it's a smaller loss than the 3.7 million acres of 2015, the perennial loss of grasslands is a threat to water quality and wildlife habitat in the Plains, which stretch from Texas into the Canadian prairies.

Record-setting Gulf dead zone may get worse

This past spring, Louisiana-based professor Dr. Nancy Rabalais, perhaps the world’s most renowned researcher on marine dead zones, predicted that the summer of 2017 would see the largest hypoxic area in the Gulf of Mexico in recorded history. Last month she was proven right.

USDA allots $328 million for Gulf-area agricultural lands

A variety of USDA programs will be tapped to provide $328 million in technical and financial assistance to improve water quality and restore coastal ecosystems over three years on agricultural land in the Gulf of Mexico area, said USDA. The strategy calls for conservation improvements on 3.2 million acres of high-priority land in 200 counties and parishes.

Less nitrogen runoff from bioenergy grass than row crops

Fertilizer runoff could be reduced significantly if row crops such as corn and soybeans are replaced with perennial grasses harvested for biofuel production, say researchers from four Midwestern universities. Nitrogen runoff in the Mississippi River basin, blamed for creation of a "dead zone" each summer in the Gulf of Mexico, could drop 15-20 percent if switchgrass or miscanthus were planted on a quarter of the land now devoted to row crops, according to computer simulations.

Largest Gulf ‘dead zone’ in 13 years due to spring rains

The "dead zone" in the Gulf of Mexico is the largest since 2002 and more than three times bigger than the target set by the so-called Hypoxia Task Force.

A “dead zone” the size of Connecticut in Gulf this year

Scientists forecast an average-sized "dead zone" in the Gulf of Mexico this year of 5,483 square miles, "or about the size of Connecticut," says the U.S. Geological Survey.

Cost to reduce Gulf of Mexico “dead zone”- $2.7 billion a year

It would cost $2.7 billion a year to reduce by two-thirds the size of the "dead zone" in the Gulf of Mexico through reductions in nutrient runoff, says a study published in the journal Proceedings of the National Academy of Sciences.

Three Iowa farm groups form water-quality alliance

Groups representing soybean, corn and hog farmers in Iowa formed an alliance to encourage farmers in the Hawkeye state to voluntarily reduce nutrient runoff, said DTN.
