Coral reef ecosystems support important commercial, recreational, and subsistence fishery resources in the U.S and its territories. Fishing also plays a central social and cultural role in many island and coastal communities, where it is often a critical source of food and income.
The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations. Such losses often have a ripple effect, not just on the coral reef ecosystems themselves, but also on the local economies that depend on them. Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats.
Coral reef fisheries, though often relatively small in scale, may have disproportionately large impacts on the ecosystem if conducted unsustainably. Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.
The natural world is a complex system. Only by understanding how species relate to each other and their environment can we hope to properly protect wildlife and preserve their habitat for the future.
Calls for increased international competency in U.S. college graduates and the global nature of the renewable energy industry require an exploration of how to incorporate a global perspective in STEM curricula, and how to best develop faculty providing them with global knowledge and skills necessary to update and improve existing teaching practices. To expand awareness of the global renewable energy sector, a cohort of renewable energy
educators from across the United States participated in two international learning exchanges to Australia/New Zealand and Germany/Denmark. The exchanges provided opportunities for the participants to meet with technical educators, visit teaching labs, review industry partnerships, talk with policy makers and government representatives, and to share knowledge and best teaching practices. Three years after the initial international
exchange, participant data was collected to measure the extended impact of the experience and the perceived value of various learning activities. The results show that the exchanges expanded participantâ€™s knowledge of renewable energy technologies and issues both in the U.S. and abroad, and also influenced teaching curriculum and instruction, and academic community engagement. This study serves as a model program for providing STEM faculty with rich international experience. The findings in this manuscript highlight the key components to building a successful international professional development program, and illustrate the type of impacts that can result from these activities. The lessons learned are meaningful to other institutions or organizations planning similar
international activities in a variety of disciplines.
Tight budgets, limited resources, new regulations, unexpected problems, citizen concerns, â€œto doâ€ lists that stretch over decadesâ€”stormwater management at the community level is often about how people collaborate and make day-to-day decisions. When faced with a new technology, program managers need to know whether it will mesh with the culture of their organization. Will staff and contractors understand how to install the new systems? Do they have the resources on hand to build them? Can they be maintained without blowing the budget? Will they protect water quality and help meet regulatory requirements?
In 12 years of working alongside communities, we have found that the answer to such questions is â€œyesâ€ when two essential ingredients are present. The first is a communityâ€™s capacity to evaluate innovative designs and practices and make them their own. And the first depends on the secondâ€”a local champion with the respect, trust, and power to put new science-based stormwater management technologies into practice and inspire real cultural change for the future. These case studies illustrate what can happen when these necessary ingredients for change meet some of the biggest challenges faced by stormwater managers nationwide.
Hands-on teaching activity describing molybdenum, a key mineral nutrient.
New 598,000 square-mile protected area is more than twice the size of Texas, and will protect everything from penguins to whales.
The Children & Nature Network is leading the movement to connect all children, their families and communities to nature through innovative ideas, evidence-based resources and tools, broad-based collaboration and support of grassroots leadership.
The Arctic region is changing rapidly, in ways that could dramatically affect peopleâ€™s lives and ecosystems. Climate change is a major concern, but rapid economic development and social transformation could also make significant impacts.
Some changes may be gradual, but there may also be large and sudden shifts. For those charged with managing natural resources and public policy in the region, it is crucial to identify potential thresholds to prepare effectively for an uncertain future.
The Arctic Resilience Report is a science-based assessment that aims to better understand the integrated impacts of change in the Arctic. Its goals are to:
â€¢ Identify the potential for shocks and large shifts in ecosystems services that affect human well-being in the Arctic.
â€¢ Analyze how different drivers of change interact in ways that affect the ability of ecosystems and human populations to withstand shocks, adapt or transform.
â€¢ Evaluate strategies for governments and communities to adapt.
The Arctic Resilience Report is led by the Stockholm Environment Institute and the Stockholm Resilience Centre and engages experts from across the Arctic.
Chemists uniquely understand how to manipulate matter. Chemists have been responsible for deeply understanding the material world and how it functions. More importantly, perhaps, they have also played a significant role in creating the material basis of our society and economy.
Building on this unique role in society, current chemists are faced with a pressing question: how we can preserve and increase the pace of innovation fundamentally supported and enhanced by the chemical sciences while not adversely affecting human health and the environment? There is substantial evidence to suggest that this is not a genuine conundrum and that evidence is found in the field of green chemistry.
An unprecedented 40-year experiment in a 40,000-acre valley of Yosemite National Park strongly supports the idea that managing fire, rather than suppressing it, makes wilderness areas more resilient to fire, with the added benefit of increased water availability and resistance to drought.
