How five global regions could achieve a successful, equitable ‘Blue Economy’

The future of an equitable and sustainable global ocean, or “Blue Economy,” depends on more than natural or technological resources. A new study finds that socioeconomic and governance conditions such as national stability, corruption and human rights greatly affect different regions’ ability to achieve a Blue Economy — one that is socially equitable, environmentally sustainable and economically viable. A paper published March 17 in Nature by the University of Washington-based Nippon Foundation Ocean Nexus Center suggests how different parts of the world might begin to achieve these goals.

We’re coping with COVID by going outdoors, but how is nature coping with us?

If you’ve hit the trails or the water this year, you know COVID-19 has transformed the way many people are recreating in our wild spaces. Places that were previously “off the beaten track” are as popular as they’ve ever been, and the usual hotspots are overwhelmed with hikers, campers and skiers. What does this mean for our wild spaces, and how can we be better stewards?

In Brazil, many smaller dams disrupt fish more than large hydropower projects

The development of small hydropower dams is widespread throughout Brazil and elsewhere in the world, vastly overshadowing large hydropower projects. The proliferation of these smaller dams is a response to growing energy and security needs. Their expansion, however, threatens many of the remaining free-flowing rivers and biodiverse tropical regions of the world — interrupting the migrations of freshwater fishes, on which millions of peoples’ livelihoods depend.

Marine-related Learning Networks’ role in ocean governance

Healthy ecosystems buzzing with life are more than something pretty to look at – they are critically important to our health and wellbeing. Ecosystems deliver goods and services that humans need – like fresh water, protection from the elements and food for our dinner tables – and it’s in our best interest to make sure they remain vibrant and thriving for future generations.

More management measures lead to healthier fish populations

Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability. The study, led by Michael Melnychuk of the University of Washington’s School of Aquatic and Fishery Sciences, draws upon the expertise of more than two dozen researchers from 17 regions around the world.
