Marine Protected Areas (MPAs) demonstrate promise for increasing ecosystem resilience and reversing habitat and population declines, but outcomes vary considerably from context to context. Partially protected areas offer a compromise between ecological recovery and the social needs of local communities, but their success is contingent on an array of factors.

Pour limiter le risque d'inondation par débordement des stations d'épuration, conséquence des averses brutales survenues après des semaines de sécheresse, la compagnie des eaux Southern Water, qui opère en Angleterre et au pays de Galles, aurait ouvert les vannes et déversé ses eaux usées directement dans l'Atlantique et la Manche, contaminant ainsi toutes les plages du littoral se trouvant à proximité des canalisations.

Marine protected areas, or MPAs as they’re more commonly called, are very simple. Areas of the sea are set aside where certain activities – usually fishing – are banned or restricted. Ideally, these MPAs might be placed around particularly vibrant habitats that support lots of different species, like seagrass beds or coral reefs. By preventing fishing gear such as towed seabed trawls from sweeping through these environments, the hope is that marine life will be allowed to recover. When used well, they can be very effective.

Scientists, policy makers and journalists are three key, interconnected players involved in prioritizing and implementing solutions to mitigate the consequences of anthropogenic pressures on the environment. The way in which information is framed and expertise is communicated by the media is crucial for political decisions and for the integrated management of environmental issues. Here we present a comparative study of scientific literature and press articles addressing climate change and biodiversity. We extensively scrutinized the scientific literature, research funding and press articles from the USA, Canada and United Kingdom addressing climate change and biodiversity issues between 1991 and 2016.

A l'aide de micros, des scientifiques enregistrent les sons des écosystèmes naturels. Après les océans et les forêts, une équipe de l'université de Bristol (Royaume-Uni) a dévoilé le monde sonore mystérieux... des mares de la campagne anglaise. Un "orchestre" étonnant.

The management of our coastal waters plays an important role in protecting and conserving our marine ecosystems. The Marine Conservation Team at the MMO are responsible for the implementation of management in certain marine protected areas (MPA) in English waters. We will be writing a series of blog posts explaining what and how we manage these MPAs, starting at the beginning, with what is an MPA?

The naturalist uses a UN event to call on world leaders to do more to protect nature. Craig Bennett, chief executive of The Wildlife Trusts, said "a much greater level of urgent action" was needed to put nature into recovery, including rescuing wildlife sites currently in decline. The government figure of 26% includes national parks and areas of outstanding natural beauty (AONBs), which are more about how our landscape looks as opposed to the state of nature within them, he said. He told BBC News: "The reality is, at best what's being managed for nature at the moment is only 10%. Even according to the government's own advisers on nature, they say half of that is in a poor condition, so it's nearer 5%. We've got a mountain to climb if we're really going to put nature into recovery in this country and reach the Prime Minister's target by 2030."
