Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information.

The UN Paris Agreement puts in place a legally binding mechanism to increase mitigation action over time. Countries put forward pledges called nationally determined contributions (NDC) whose impact is assessed in global stocktaking exercises. Subsequently, actions can then be strengthened in light of the Paris climate objective: limiting global mean temperature increase to well below 2 °C and pursuing efforts to limit it further to 1.5 °C. However, pledged actions are currently described ambiguously and this complicates the global stocktaking exercise.'

Up to 2.5 billion people hold and use the world’s community lands, yet the tenure rights of women—who comprise more than half the population of the world’s Indigenous Peoples and local communities—are seldom acknowledged or protected by national laws.

The watchdog NGO Mighty Earth followed up its February investigation into deforestation for soybean production and found that companies are sourcing from farms in Brazil and Bolivia where clearance

The spread of pests and pathogens that damage plant life could cost global agriculture $540 billion a year, according to a report published on Thursday.

Small but inevitable rises in sea level will double the frequency of severe coastal flooding in most of the world with dire consequences for major cities that sit on coastlines, according to scient

Dengue is the most important arthropod-borne viral infection of humans, it is established in the tropics worldwide, and its geographical expansion is expected to increase due to factors such as modern dynamics of climate change, globalization, travel, trade, poverty, unplanned urbanization, and viral evolution. The World Health Organization (WHO) estimates that 2.5 billion people are at risk of infection, with 50–100 million infections per year.

Government-administered adulticiding is frequently conducted in response to dengue transmission worldwide. Anecdotal evidence suggests that spraying may create a “false sense of security” for residents. Our objective was to determine if there was an association between residents’ reporting outdoor spatial insecticide spraying as way to prevent dengue transmission and both their reported frequency of dengue prevention practices and household entomological indices in Hermosillo, Mexico.

Deadly infectious pandemics will mark humanity's future, as they have shaped its past. Neither individual governments nor the global community can entirely prevent the emergence of infectious threats. But we can be much better prepared.

Semipalmated Sandpiper (Calidris pusilla) populations have undergone significant declines at core nonbreeding sites in northeastern South America. Breeding populations have also declined in the eastern North American Arctic, but appear to be stable or increasing in the central and western Arctic.
