Sustainable and healthy food to feed the world in 2050: Nature study
10/10/2018 - “Feeding a world population of 10 billion people is possible - yet only if we change the way we eat, and the way we produce food, our research shows. Greening the food sector or eating up our planet: this is what is on the menu today,” says Johan Rockström, Director Designate of the Potsdam Institute for Climate Impact Research. He’s one of the authors of a new study now published by an international team of scientists in the journal Nature.

New Report “The World in 2050”: Sustainable development experts meet in New York
07/10/2018 - From education and health to responsible consumption, a decarbonized energy-system, agriculture, sustainable cities and digitalization - six transformations are necessary to achieve the Sustainable Development Goals (SDGs) set by the United Nations, a new report by leading experts in the field finds. Published at the High-Level Political Forum on Sustainable Development (HLPF) in New York this week, the new report prepared by The World in 2050 (TWI2050) initiative outlines the key points that are necessary to bring the world on target to a sustainable future. More than 60 authors and 20 organizations were involved in the report, among them Johan Rockström, current Director of the Stockholm Resilience Centre and designated Director of the Potsdam Institute for Climate Impact Research (PIK), as well as PIK researchers Elmar Kriegler, Hermann Lotze-Campen and Alexander Popp.

Spacefood for cows: Industrial microbes could feed cattle, pigs and chicken with less damage to the environment
06/20/2018 - Deforestation, greenhouse gas emissions, biodiversity loss, nitrogen pollution – today’s agricultural feed cultivation for cattle, pigs and chicken comes with tremendous impacts for the environment and climate. Cultivating feed in industrial facilities instead of on croplands might help to alleviate the critical implications in the agricultural food supply chain. Protein-rich microbes, produced in large-scale industrial facilities, are likely to increasingly replace traditional crop-based feed. A new study now published in the journal Environmental Science & Technology for the first time estimates the economic and environmental potential of feeding microbial protein to pigs, cattle and chicken on a global scale. The researchers find that by replacing only 2 percent of livestock feed by protein-rich microbes, more than 5 percent of agricultural greenhouse gas emissions, global cropland area and global nitrogen losses could each be decreased.

Mix it: Policy combination needed to achieve climate targets along with sustainable development goals
06/20/2018 - A broad combination of policies might be best suited to help achieve both climate stabilization targets as well as most of the UN Sustainable Development Goals. These policies reach from straightforward CO2 pricing to regulation of water and forest protection, to lifestyle changes such as eating less meat, a new study shows. The scientists highlight the complex interplay between the different targets. A policy focused only on CO2 pricing would cost the least, they show, but would likely trigger substantial land-use changes.
