Showing results for: GHG impacts and mitigation
This book tells the stories of 13 foods that are endangered by climate warming, discusses their origins and histories, and suggests how to protect them.
This paper finds that targeting ecosystem restoration efforts towards 15% of converted lands (i.e. areas that have been converted away from their natural state to cropland or pasture) could prevent 60% of expected extinctions in mammals, amphibians and birds and sequester 299 Gt CO2. It identifies differing priority areas depending on whether the outcomes are optimised for biodiversity, climate mitigation, cost minimisation or all three.
This book by FCRN member Paul Behrens uses paired chapters of pessimism and hope to show how much needs to be done to achieve a hopeful future, but how this would involve actively building a healthier and more fulfilling world. The book covers subjects including food, energy, climate and economics.
In this report, UK food waste NGO Feedback critically assesses the narrative that anaerobic digestion (AD) is a viable solution for producing renewable gas from organic matter such as crops and wastes. The report argues that preventing food waste in the first place is more effective than generating biogas from waste food, particularly if trees were to be planted on the land spared.
This paper addresses recent concerns about RCP8.5, a climate scenario developed by the Intergovernmental Panel on Climate Change based on an assumption of high levels of fossil fuel use. A recent commentary argues that RCP8.5 was originally intended to explore an unlikely future with no climate mitigation, but that it is now commonly referred to as a “business as usual” scenario by the media. In response, this paper argues that RCP8.5 is indeed a good match for current and stated climate policies up until 2050.
This progress report from the UK’s Committee on Climate Change assesses progress in reducing UK greenhouse gas emissions over the past year and makes recommendations on how to ensure the post-COVID-19 recovery is green and resilient. It includes discussions of agriculture, diets and land-use change.
The Global Alliance for the Future of Food held the Salzburg Process on the Climate Emergency and the Future of Food in May 2020. In this blog post, Ruth Richardson (Executive Director of the Global Alliance) reflects on lessons learned from holding the event virtually because of COVID-19, rather than physically as originally planned.
This blog post John Lynch of Oxford’s Livestock, Environment and People programme asks whether we can keep farming cows and sheep without dangerously warming the planet. He points out that it is possible to maintain stable temperatures without eliminating methane emissions entirely (in contrast to CO2 where emissions have to fall to net zero to tackle climate change). However, ruminant methane emissions are currently increasing. Furthermore, ruminants use a lot of land, some of which could be used for other purposes that might sequester more carbon.
The average number of days that US farm workers spend working in dangerously hot conditions could double by mid-century and triple by the end of the century, according to this paper. Workplace adaptations such as longer rest breaks, working more slowly, switching to single-layer clothing and having cooled rest areas could tackle this problem, but would negatively affect farm productivity, worker earnings and labour costs.
This paper uses temperature and precipitation projections across the ranges of over 30,000 species on land and in water to estimate when each species will be exposed to dangerous climate conditions. It predicts that most species within a given assemblage (group of species within a habitat) will encounter inhospitable climate conditions at the same time as each other (e.g. several species might have a similar upper limit on the temperature that they are able to cope with), meaning that disruption of the overall assemblage is likely to be abrupt.
This book examines how the food system can adapt to be able to produce enough food in a changing climate. The authors present global policy options and list key foods that could help, including algae, caribou and kale.
This paper uses several simple emissions scenarios to illustrate how GWP* (as opposed to GWP100) can report the warming created by both short-lived greenhouse gases such as methane (CH4) and long-lived greenhouse gases such as carbon dioxide (CO2).
This book looks at the tradeoffs between mitigating climate change and protecting food security, as well as the effects that climate change has on food production.
This book by Sarah Bridle provides an accessible outline of the links between climate change and food: both the climate impacts of producing food, and the impacts of climate change on farming.
This report, commissioned by the UK charity Royal Society for the Protection of Birds, assesses a selection of measures for reducing greenhouse gas emissions from agriculture. It looks at their potential impacts on biodiversity, climate and resource protection to identify which solutions offer synergy between climate and nature, and where there is a risk of conflict.
This piece in the UK’s Independent newspaper, by several researchers from the University of Oxford, sets out five questions that (they argue) should be considered by any policymaker or business setting a “net zero” greenhouse gas emissions target.
Our World in Data has published this piece, which breaks down the extent to which the differences in carbon footprints of food categories can be attributed to methane, a short-lived greenhouse gas which has attracted controversy over how its climate impact is measured.
