Over the last 50 years, human diets around the world have grown ever more similar and the trend shows no signs of slowing, with major consequences for human nutrition and global food security, according to research carried out at International Center for Tropical Agriculture.

Climate change could force Chipotle to temporarily stop serving guacamole, the fast-food chain warned in a recent filing with the Securities and Exchange Commission. The notification, which Chipotle described as a "routine financial disclosure," notes that climate-induced freezes and droughts can take a severe toll on food-based supply chains, leading to price spikes and product shortages

Bees, butterflies and other pollinators are increasingly under threat from human activities and countries must transform their agricultural practices to ensure global crop production can meet demand and avoid substantial economic losses, the United Nations Conference on Biological Diversity heard today. According to the global assessment on pollinators produced by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), 75 per cent of our food crops and nearly 90 per cent of wild flowering plants depend to some extent on animal pollination, which is the transfer of pollen between the male and female parts of flowers to enable fertilization and reproduction. Without pollinators, crops such as coffee, cacao and apples would drastically suffer, and changes in global crop supplies could increase prices to consumers and reduce profits to producers, resulting in a potential annual net loss of economic welfare of $160 billion to $191 billion globally.

A new peer-reviewed study shows that widespread use of algae in animal feed could help limit the rise in global temperature to 2°C by 2100 and possibly even turn back the clock, bringing atmospheric carbon concentrations down to pre-industrial levels by the end of the century. Algae-based feeds have proven to be equal to or better than other feedstocks in nutritional value and digestibility, and could free large swaths of arable land and simultaneously address food security issues in an era of rising demand for animal proteins.

DuPont launched its 2020 Sustainability goals, which include investing $10 billion in research and development to enhance global food security, cutting GHG emissions intensity by 7% from a 2015 baseline, reducing non-renewable energy use by 10% from a 2010 baseline, and more.

"We recognize that the well-being of people and the sustainability of our oceans are interdependent," said Buster Houston, director of seafood at Albertsons Cos., in a prepared statement. "As one of the largest U.S. retailers of seafood, we are committed to protecting the world's oceans so they can remain a bountiful natural resource that contributes to global food security, the livelihoods of hard-working fishermen and the global economy."

Albertsons has committed to preventing and reducing marine pollution, working to cut down on ocean acidification, taking better control of overfishing practices and other initiatives under the United Nations' sustainable "Oceans Goal." The retailer has also become part of the Seafood Task Force, which targets unregulated and illegal fishing
