Why we need to put the fish back into fisheries

Overfishing has reduced fish populations and biodiversity across much of the world's oceans. In response, fisheries are increasingly reliant on a handful of highly valuable shellfish. However, new research by the University of York shows this approach to be extremely risky. The ecological effects of intensive fishing. From left to right, fishing effort increases over time. As a...

New era of fisheries policy needed to secure nutrition for millions

Securing the critical contribution of wild fish stocks to food and nutrition security in the developing world depends on better governance and management of the fisheries sector. Fish is a key source of animal protein, fatty acids, vitamins, and micronutrients like iron and zinc that contribute to a balanced diet, and is a particularly important food source in many developing countries....

Large-scale edible insect farming needed to ensure global food security

The large-scale production of edible insects is unavoidable in order to continue feeding the ever-increasing global population and providing them with enough animal protein. Insect farming can be compared with mini livestock farming. It is environmentally friendly, does not require much land and produces high-quality nutrients. Furthermore, as a new sector of the food industry, it will...

Reducing the environmental impacts of fertiliser use

Scientists have demonstrated how improvements in nitrogen fertiliser manufacture and their application could help reduce China's agricultural greenhouse gas emissions by around 60%, by 2030, compared to the current business as usual approach. This emissions reduction represents a 2 to 6% reduction in China's overall greenhouse gas emissions and therefore could be significant in the...

Flower power fights orchard pests

Washington State University researchers have found they can control one of fruit growers’ more severe pests, aphids, with a remarkably benign tool: flowers. The discovery is a boon for organic as well as conventional tree fruit growers.  The researchers recently published their study in the journal Biological Control. They found that plantings of sweet alyssum attracted a...

Poultry drug increases levels of toxic arsenic in chicken meat

Chickens likely raised with arsenic-based drugs result in chicken meat that has higher levels of inorganic arsenic, a known carcinogen, according to a new study led by researchers at the Johns Hopkins Center for a Livable Future  at the Bloomberg School of Public Health. This is the first study to show concentrations of specific forms of arsenic (e.g. inorganic arsenic versus...
