Staff Report

FRISCO — Expediting construction of a planned transoceanic canal in Nicaragua raises a host of environmental and social issues, according to a panel of scientists who recently met at a conference to discuss the potential impacts of the project.

The scientists urged caution and international collaboration, saying that sediment discharges during construction will threaten aquatic species, Nicaragua’s lucrative ecotourism and the supply of fresh water for drinking, irrigation and power generation.

The Nicaragua Interoceanic Grand Canal will cut through Lake Cocibolca , Central America’s main freshwater reservoir and the largest tropical freshwater lake of the Americas. The plan will force the relocation of indigenous populations and impact a fragile ecosystem, including species at risk of extinction, according to Rice University environmental engineer Pedro Alvarez and other members of the consortium.

UN says big investments needed to avert water wars

Will the world get it together on climate change?

Will the world get it together on water?

Upfront spending would avoid the huge costs of escalating conflicts

Staff Report

FRISCO — Big investments in water infrastructure are needed around the world to avert future conflicts over the world’s most essential resource. Looming shortages of water could trigger conflicts and mass migrations, contributing to social and political instability, the report warns.

“The consequence of unmet water goals will be widespread insecurity creating more international tension and conflict,” said lead author Bob Sandford. “The positive message is that if we can keep moving now on water-related sustainable development goals we can still have the future we want,” he said.

Detailed mapping can help plan climate change adaptation

Staff Report

FRISCO — Huge wildfires have driven the conversion of Alaska forests to grass- and shrublands, and the state’s perennial ice and snow fields, as well as its vast wetlands are also shrinking, according to the U.S. Geological Survey.

The changing face of Alaska is revealed in a new land-cover data set, which provides detailed information useful to land use planners and decision-makers. Continue reading

Nevada Supreme Court rejects Las Vegas pipeline scheme

In a desperate quest for more water, Las Vegas wants to deplete distant aquifers with no regard for natural and environmental resources.

New lawsuit filed to void federal OK for proposed desert pipeline

Staff Report

FRISCO — A recent ruling by the Nevada Supreme Court appears to reinforce arguments by conservation advocates that a scheme to develop and pipe groundwater to Las Vegas can’t pass scientific, environmental or legal muster.

The Southern Nevada Water Authority wants to siphon 37 billion gallons from remote underground aquifers in a plan that was challenged by the Center for Biological Diversity and its allies in the Great Basin Water Network, as well as by White Pine County, Nev.

In 2011, the Nevada Division of Water Resources gave the project a thumbs-up by allocating 84,000 acre-feet of ancient groundwater a year to the Southern Nevada Water Authority for export to Las Vegas, but Senior Judge Robert Estes of the Seventh Judicial District Court of Nevada said that allocation is unfair to future Nevadans and not in the public interest.

Science team tracks effects of historic pulse flow

Staff Report

FRISCO — Last May’s pulse flow in the Colorado River helped revive vegetation along a huge swath of the river’s edge, triggering new plant growth and raising the water table in the delta. After comparing satellite images taken August 2013 with new images from this year, scientists calculated a 23 percent increase in the greenness of riparian zone vegetation. Continue reading

Conservation groups say the river fish needs endangered species protection

Staff Report

FRISCO — Wrangling over the fate Montana’s Arctic grayling will continue in court, as conservation groups this week challenged a federal finding that the fish don’t need Endangered Species Act protection.

Graylings are part of the salmon family, native to cold freshwater streams and rivers across Canada and Alaska, with a genetically distinct population in Montana that was nearly wiped out by the 1970s. Continue reading
