The coming decade may determine whether humanity will set a course toward a more socially and ecologically sustainable society. A crucial part of this goal is to develop a better understanding of how cooperation can be improved and become more effective, both within and among private stakeholders and public institutions.

“Collaborative governance is often highlighted as a solution to different environmental problems. For example, when small-scale fishermen agree to avoid overfishing or when states agree to reduce greenhouse gases. But we don’t know so much about how cooperation around environmental issues works in a complex world. Different actors want different things, different environmental problems are related to each other, and different groups have differing amounts of influence. Does cooperation actually lead to a better environment?” says Örjan Bodin, lecturer at the Stockholm Resilience Centre who conducts interdisciplinary research on better ways to handle diverse environmental problems.

Researchers have developed a method to evaluate atmospheric conditions using mosses (bryophytes) in urban areas, a development that could facilitate broader evaluations of atmospheric environments.

Many urban areas face atmospheric problems such as pollution and the heat island effect. With the need to evaluate atmospheric conditions, bioindicators—organisms whose response to environmental changes indicates the health of an ecosystem—have attracted considerable attention. Their merits include being able to evaluate an environment over a wide area at a low cost; detect environmental changes over an extended period; and assess these changes’ effects on the ecosystem. Bryophytes are one such group of plants known to be sensitive to environmental changes, in particular to atmospheric conditions.

CFCs, greenhouse gases, and naturally occurring emissions of halogens will shape how volcanoes impact the ozone layer into the next century 

In a new study, researchers at The Ohio State University estimate algal blooms at two Ohio lakes cost Ohio homeowners $152 million in lost property value over six years.

Meanwhile, a related study suggests that algae is driving anglers away from Lake Erie, causing fishing license sales to drop at least 10 percent every time a bloom reaches a moderate level of health risk. Based on those numbers, a computer model projects that a severe, summer-long bloom would cause up to $5.6 million in lost fishing revenue and associated expenditures by anglers.

Bumblebees are less able to start colonies when exposed to a common neonicotinoid pesticide, according to a new University of Guelph study.

Prof. Nigel Raine has discovered that exposure to thiamethoxam reduces the chances of a bumblebee queen starting a new colony by more than one-quarter.

Invasive mussels and less nutrients from tributaries have altered the Lake Michigan ecosystem making it more conducive to the stocking of lake trout and steelhead than Chinook salmon, according to a recent U.S. Geological Survey and Michigan State University study.

Reduced stocking of Chinook salmon, however, would still support a substantial population of this highly desirable recreational salmon species, which is a large contributor to the Great Lakes multi-billion-dollar recreational fishery.

“Findings from our study can help managers determine the most viable ways to enhance valuable recreational fisheries in Lake Michigan, especially when the open waters of the lake are declining in productivity,” said Yu-Chun Kao, an MSU post-doctoral scientist and the lead author of the report.

The Sungazer (Smaug giganteus), a dragon-like lizard species endemic to the Highveld regions of South Africa, is facing an assault on two fronts as farming and industrialisation encroaches on its natural habitat – which already consist of only a several hundred square kilometres globally – while the illegal global pet trade is adding pressure on pushing the species into extinction.

As the world population continues to balloon, agricultural experts puzzle over how farms will produce enough food to keep up with demand. One tactic involves boosting crop yields. Toward that end, scientists have developed a method to make a low-cost, biocompatible fertilizer with carbon dots derived from rapeseed pollen. The study, appearing in ACS Omega, found that applying the carbon dots to hydroponically cultivated lettuce promoted its growth by 50 percent.

The world’s oceans possess vast, untapped potential for sustainable aquaculture, say UCSB marine scientists.

A global analysis of rainfall and rivers by UNSW engineers has discovered a growing pattern of intense flooding in urban areas coupled with drier soils in rural and farming areas.
