“Imagine it is 2030, and we now live in a world in which the transition to a just and sustainable post-carbon society has occurred. There is now real hope that runaway climate change will be avoided. How did this happen?” The Melbourne Sustainable Society Institute, University of Melbourne and the Centre for Policy Development set out to answer this ambitious question in a recently published report outlining large-scale, post-carbon economy transition strategies. The authors begin by striking a hopeful tone, stating, “From Germany to California … the United Kingdom to China, the global momentum for implementation of large scale de-carbonisation strategies is rapidly accelerating.” But they also pull no punches in outlining existing challenges such as climate science denial, the influence of the fossil fuel industry, political paralysis, unsustainable consumption of energy and more.

Conservationists may soon have a powerful new tool in the fight against illegal fishing. FishNET, developed by the Center for Ocean Solutions, is a Web-based system that relies on crowdsourcing, drone technology and satellites to monitor and report illegal fishing activities across the globe. The platform holds particular promise for parts of the world that currently lack sufficient monitoring and enforcement. According to project founder and National Geographic Emerging Explorer Shah Selbe, “The oceans are at a critical turning point. Our ability to reverse the effects of the last 50 years of accelerated industrial fishing and protect the earth’s last great frontier is within our capabilities.” The technology also has the potential to curb illegal pollution, ecosystem destruction, illegal wildlife trade and other conservation challenges.

For years light-emitting diodes have been seen as a greener alternative to incandescent and fluorescent bulbs. But they come with a cost — both literally and figuratively, since most LEDs are made from rare-earth elements that are expensive and hazardous to extract and process. A team of researchers at the University of Washington has come up with an alternative that’s easier on the eye, the pocketbook and the environment. Using silicon-based nanoparticles derived from sand, the budding entrepreneurs have developed LEDs that more closely mimic natural sunlight for a fraction of the cost of standard LEDs. The future is looking bright — and welcoming — indeed. Photo by samsungtomorrow (Flickr | Creative Commons)

Many fruits, nuts and other food crops depend on pollinating insects for success. Yet modern farms often grow such plants in large monocultures, discouraging the presence of pollinators by reducing the availability of diverse, insect-friendly native vegetation. Looking for a way to make large plantations more welcoming to these beneficial insects, researchers in South Africa added patches of native flowering plants to mango orchards. They found that while mangoes distant from native vegetation showed 47 percent lower pollinator diversity than those near natural settings, mangoes in the orchards with small plots of native plants showed only a 7 percent drop. Not only that, but the orchards with patches of natives produced an extra 1.5 kilograms of fruit per tree — more than making up for the cost of the added plantings.

Biodiversity seems to be having a tough go of it lately. Many scientists believe we’re in or entering a sixth mass extinction, and given that we discover 15,000 or more new species each year, we’re bound to lose some things we never even knew existed. Still, those 15,000 or so are cause for a renewed sense of awe every year when looking at our planet. Which is exactly how Quentin Wheeler, founding director of the International Institute for Species Exploration at Arizona State University, feels. “I don’t know whether to be more astounded by the species discovered each year, or the depths of our ignorance about biodiversity of which we are a part,” he said as the IISE recently announced its annual list of top 10 new species. The list — which includes a new monkey with “human-like eyes,” a butterfly discovered through social media and the world’s smallest vertebrate — not only serves to highlight some of the strangest and most interesting species among us, but also as a sounding bell meant to raise awareness about biodiversity loss.

Is your city taking steps to prepare for a changing climate and related extreme weather events? The International Council for Local Environmental Initiatives (ICLEI) recently announced its list of 20 leading resilient cities across the United States. Communities at the top of the list are finalizing climate action plans, scaling renewable energy, shoring up coastal wetlands, developing water conservation plans, improving energy efficiency and much more.

How should conservation reserves be configured to offer the biggest benefit for biodiversity in the face of climate change? Although there are many options, little concrete evidence exists as to which is best. In a study reported in a recent issue of the Journal of Applied Ecology, Australian scientists applied a new model to assess whether putting a premium on connectivity, aggregation or representativeness — or balancing all three — would be most beneficial. Using plant biodiversity in Tasmania as a test case, they found the answer depended on the conservation goal: Boosting representativeness offered the best results with respect to total species diversity, but aggregation and balanced strategies made the most sense for increasing the average area of occurrence for all species. Concluding that “adherence to a single habitat configuration strategy … is unlikely to result in the best outcomes for biodiversity under climate change,” the researchers encouraged conservation practitioners to tailor strategies to desired outcomes rather than take a one-size-fits-all approach.

Can urban farms be fun as well as functional? As interest in producing food in cities grows, so do visions for hybridizing function with aesthetics in innovative and entertaining ways. Among the ideas that have taken root in architects’ imaginations are a 132-story dragonfly-shaped vertical garden powered by the sun and wind; a geodesic greenhouse whose angled panels direct winter light to plants throughout the interior; plant-mimicking towers with “stems” that carry water to food-producing plots arrayed like leaves; a combined apartment building, greenhouse and chicken farm; and a literal food pyramid. They’re not all just pie in the sky, either: One such “farmscraper,” a 175-foot-tall greenhouse planned for Linköping, Sweden, is scheduled to begin producing food as early as next year.

Keeping tabs on plant and animal phenology is important as the climate changes around us. Just where and when plants and animals are popping up, sticking around, migrating to or abandoning all together is key to understanding what exactly is taking place as our world warms. So, for easy reference the USA National Phenology Network put together a series of eight quick-hit informational PDFs that show changes in phenology over the last 100 years by U.S. region. Now you have one easy destination to find out anything from how many days earlier winter wheat is blooming in the Great Plains to how higher water temperatures in Alaska and the Arctic may affect pink salmon fry migration. Photo by Dr.DeNo (Flickr | Creative Commons)

Plastic pollution is ubiquitous – and an especially serious and confounding problem in the world’s oceans, where immeasurable amounts of plastic debris are scattered. A feasibility study is underway to build and test a network of fixed vessels with winglike, floating booms that could potentially remove 55 shipping containers worth of plastic per day. Called Ocean Cleanup Arrays, the network would be solar-powered and use currents to divert plastic into the vessels to store for later removal and recycling.

To assess a heart’s health, doctors use an EKG. To assess the health of America’s ecosystems, scientists are setting into place a nationwide network that will use standardized tools and techniques to track long-term changes in air and water quality, plant and animal populations, climate, and more. Known as the National Ecological Observatory Network, the National Science Foundation–funded system will gather observations from more than 100 monitoring stations over a 30-year period, with data, models and related educational materials all available free online. Although it’s not expected to be fully functional until 2017, NEON already has several projects underway, including assessment of conditions in Colorado following last summer’s fires, a season-tracking initiative known as Project Budburst, a citizen science academy for educators and an undergraduate internship program.

With the proportion of Africans living in cities expected to climb from 18 percent in 1950 to 56 percent by 2030, building materials will be in greater demand than ever. Rising to the task are two recent studies reporting new ways to make bricks from common materials, including mining waste and desert sand. Although more research is needed to ensure the innovative bricks can withstand extreme weather and won’t pose health risks, initial tests are promising.

What if cities could be powered by the noise they create? The Soundscraper — a building cloaked with sensors that would convert sound vibrations into electricity — could transform urban cacophony into enough power to light a small city. The design won honorable mention in the 2013 eVolo architectural magazine skyscraper competition, where participants submitted designs that would “challenge the way we understand vertical architecture and its relationship with the natural and built environments.”

The Canadian province of Ontario recently announced that it will be shuttering six more coal plants by the end of 2013. The announcement means 17 out of 19 coal plants from a decade ago will soon be decommissioned. Across Ontario greenhouse gas emissions from the electricity sector are projected to decrease from a high of 41.4 megatonnes in 2000 to only 5 megatonnes post-2020. The coal-fired plants are being replaced by a combination of power sources, including nuclear, natural gas and renewables such as hydropower. Photo by Jeffrey Beall (Flickr | Creative Commons).

Some people, communities and nations are able to weather and rebound from substantial shocks. They are, in a word, resilient. But what exactly does that mean? What characteristics confer resilience, and how can they be cultivated? In Goldilocks Had It Right: How to Build Resilient Societies in the 21st Century, New Security Beat describes eight traits of resilient systems and explores how communities can cultivate resilience in increasingly uncertain times.

Tap water, crop irrigation and other human uses around the world are using groundwater at 3.5 times the sustainable rate. In some cases, water is being sucked from aquifers (underground water-bearing formations) faster than new water can filter in. In others, “fossil aquifers” – formations that no longer replenish – are being used up. Solutions being explored include improving the efficiency of water use by agriculture and encouraging conservation in homes and businesses.

It’s easy to identify the obvious challenges to biodiversity: climate change, invasive species, habitat loss. Less obvious are the things we’re not thinking of but should. Led by Cambridge University conservation biologist William Sutherland, scientists from around the world recently completed an elaborate “horizon scanning” exercise to identify 15 relatively obscure global events and trends that stand to have huge impact on biodiversity conservation. Among them: growth of concentrated solar power, the increase in demand for coconut water and the use of antimicrobials in health care and food industries.

The European Union is betting 1 billion Euros ($1.3B U.S.) on graphene – a wonder material that is said to be 100-300 times stronger than steel and conducts electricity much better than copper. Graphene has the potential to revolutionize entire industries and can be applied to a range of applications from flexible electronics and advanced batteries to more energy efficient airplanes. The Graphene Flagship research consortium is being coordinated by Chalmers University of Technology in Gothenburg, Sweden.
