Showing results for: GHG impacts and mitigation
Online conferences have the advantage of reducing carbon emissions from travel, particularly air travel, but they can be less convenient when it comes to networking and developing personal connections. The November meeting of the European Biological Rhythms Society tried to fix this by inviting psychologists to develop remote ways of encouraging networking.
This report from Canada’s National Farmers Union examines how climate change is likely to affect agriculture in Canada, and sets out a strategy for the food system to contribute to mitigating the climate crisis. It argues that low-input, low-emission styles of agriculture should be incentivised.
This book gives a holistic overview of both the impacts of climate change on agriculture and the contribution of agriculture to climate change, describes how to predict these interactions, and offers strategies for “climate-smart agriculture”.
This commentary reviews the evidence on climate tipping points - i.e. irreversible (on a human timescale) and abrupt shifts from one climate state to another - and concludes that several interlinked tipping points could be already active or very near to being triggered. Cutting emissions could still slow down the rate at which the tipping points operate, the authors argue.
In this blog post, Asaf Tzachor of the Centre for the Study of Existential Risk at the University of Cambridge describes four pathways by which the global food system could collapse. He calls for greater awareness that interactions between different processes (such as ocean acidification, climate change, wildfires and plant diseases) could lead to vicious cycles, and argues that policymakers should seek leverage points in the food system.
This book gives examples of practices and tools that can help agriculture adapt to climate change, focusing on Japan and other nearby Asian countries.
This paper models the changes in vegetation and agricultural land use that might be expected if action is not taken to mitigate climate change. Temperatures in the UK would increase by around 5.4°C in the growing season and 4.7°C out of the growing season by the end of the century. The growing season would become drier by around 37% and the non-growing season would become 7% wetter, with drying being less pronounced in the north of the UK than the rest of the country.
In this opinion piece in the Guardian newspaper, Jess Fanzo and Mario Herrero argue that food producers, consumers and governments all need to make changes to help reduce the climate impact of the food system.
The book chapter Why sustainable plant-based diets are needed to reverse the food-climate-health-equity crisis by FCRN member David A Cleveland, part of the book Plant-based diets for succulence and sustainability, argues that plant-based diets are a key part of the response to the interlinked crises in food, climate, health and inequality.
This paper models the greenhouse gas (GHG) emissions and water footprints of both baseline consumption patterns and nine different healthy diets that prioritise plant ingredients for 140 countries. The authors find large differences in GHG and water footprints between countries, with vegan, two-thirds vegan or “low food chain” (including insects, molluscs and forage fish) diets generally leading to the greatest footprint reductions.
Michelle Cain, Myles Allen and John Lynch of the University of Oxford have published a plain-language briefing note that explains how different ways of measuring the climate impact of methane (GWP100 versus GWP*) affect definitions of net zero emissions targets.
FCRN member David Cleveland has co-authored this book, which addresses how food gardens can be used by people to respond to climate change through both adaptation and mitigation.
The World Resources Institute has released its full and final report on “Creating a sustainable food future”. The report addresses the question “Can we feed the world without destroying the planet?”, specifically asking whether the food system can feed nearly 10 billion people adequately by 2050, without expanding the area of agricultural land, and while avoiding dangerous levels of climate change.
This report from the UK’s Committee on Climate Change (CCC) sets out the UK’s current progress towards its climate goals. It finds that, since June 2018, the UK government has only delivered 1 out of 25 essential policies needed to cut emissions and only 7 out of 24 progress indicators are on track.
This paper maps the potential for restoring forests across the world, finding that there is room for a 25% increase in forested area without interfering with existing forests or urban and cropland areas. This could store 205 Gt of carbon after several decades (for comparison, current emissions from fossil fuels and cement production are roughly 10 Gt of carbon each year).
This report from the European Academies Science Advisory Board outlines the connections between climate change and human health in Europe, recommends integrating health concerns into climate mitigation strategies, and suggests areas of priority for further research.
This paper finds that production of the top ten global crops has already been affected by climate change, with mixed impacts across both crop type and geographical area. Oil palm has seen a 13% decrease in yields relative to those that would have been seen under historical climate conditions, while soybean has seen a 4% increase.
