Although it is customary for mainstream economists and politicians to consider the commons a failed management regime – the “tragedy of the commons” – it is in fact a pervasive and highly generative system for meeting people’s needs.
Sophie Gardiner and Emily Gustafson-Wright evaluate 10 common claims about impact bonds and identify five areas where the social impact bond (SIB) mechanism had a demonstrable positive effect on service provision.
Aquaculture production has more than doubled since 2000, putting pressure on the stocks of small fish used to feed farmed salmon and other species. But researchers are now developing plant-based feeds that could put the industry on a more sustainable path.
Underlying so much of the economic and ecological turmoil unfolding before us is a slow collision between the operating practices of the resource-wasting, vertically-managed 20th century and the much more crowded, polluted, and dangerous ecological and economic conditions of the 21st century.
The world lost more than 18 million hectares (45 million acres) of tree cover in 2014, an area twice the size of Portugal, according to new data from the University of Maryland (UMD) and Google released by Global Forest Watch. The data find that tropical forests are in the most trouble, losing 9.9 million hectares (24.5 million acres) of tree cover in 2014 – over half of the global total.
A new study has found that people born in 2013 can expect to live 6.2 years longer than those born in 1990. However, healthy life expectancy has not increased as much, which suggests people are also living longer with illness and disability.
Although wind power provided less than 3% of Alaska's electric power generation in 2014, Alaska's wind power capacity has increased 20-fold between 2007 and 2014, growing from 3 megawatts (MW) to 60 MW. This increase is notable in light of the challenges of installing and connecting large wind generators, specifically the high costs of expanding electricity transmission infrastructure in the least densely populated state. Alaska's nascent wind industry has sited utility-scale turbines along the Railbelt, the only large-scale transmission system in the state, and at distributed scale to supply electricity in remote or rural areas without grid access.
Affirming a trend seen in other cities, Indianapolis’s eight-mile Cultural Trail has been a boon to the neighborhoods adjacent to it — as well as the city as a whole — increasing property values of homes and businesses and giving residents and tourists a convenient, attractive, unbroken path to walk, bike and move around the city.
