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.

Innovations for sustainability in a post-pandemic future
07/07/2020 - The COVID-19 pandemic has thrust the world into turmoil and disrupted the status quo, but it is also providing opportunities for innovation in the way we live and work. According to the latest report released by The World in 2050 (TWI2050) initiative, the crisis can lead to creating sustainable societies with higher levels of wellbeing for all. Beyond political will, small-scale, granular innovations that are affordable and can be widely applied are key here.

EU Commission draft climate law is "an important step" - yet comprehensive CO2 pricing is needed: Edenhofer
Today, the EU Commission proposed a draft climate law, containing regulation to implement parts of its Green Deal plan. On this issue, Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research and Professor for Climate Economics at Technische Universität Berlin, Germany, published a statement. Setting the right targets is not enough, he argues - "we need well-defined pathways and short-term entry points to reach them".

Focus on food to address climate change
18/02/2020 - Bringing together agricultural production, supply chains, and consumption: In a comment published in the new journal Nature Food researchers discuss a new global food system approach to climate change research. When these activities are considered together, they represent 21 to 37 percent of total human-caused greenhouse gas emissions, the authors note. This new approach also enables a fuller assessment of the vulnerability of the global food system to increasing droughts, intensifying heatwaves, heavier downpours, and exacerbated coastal flooding. Food system responses thus play a major role in both adapting to and mitigating climate change, the authors assert.

Six Transformations to achieve the Sustainable Development Goals
26/08/2019 - The Sustainable Development Goals (SDGs) and the Paris Agreement on Climate Change call for deep transformations that require complementary actions by governments, civil society, science, and business. While significant progress is being made on some goals, no country is currently on track towards achieving all SDGs. PIK Director Johan Rockström contributed to a paper published now in Nature Sustainability, outlining six major transformations that will be required to achieve these ambitious goals. Led by the United Nations Sustainable Development Network (UNSDSN), the research will be an input to the upcoming United Nations General Assembly Climate Summit on September 23 and 24 in New York City. Rockström will be a speaker at a number of events.

Looking beyond the farm gate: New IPCC Special Report on Land Use and Climate Change
08/08/2019 – Almost three quarters of habitable land on earth are under human use – resulting in substantial impacts on our climate, a new report of the Intergovernmental Panel on Climate Change (IPCC) shows. Today, almost a quarter of human-made greenhouse gas emissions arise from agriculture, forestry and other land use. The latest IPCC Special Report investigates the current situation, possible future scenarios and potential solutions on how we can use land to feed ourselves, fuel economic growth and limit climate change risks. Two Potsdam scientists figure as lead authors of the chapter on food security and on the relations between land and climate.
