Knowledge for better food systems

Showing results for: Climate change: Mitigation

Climate mitigation mitigation involves actions aimed at limiting the amount of greenhouse gases in the atmosphere. This may consist in reducing anthropogenic emissions or by increasing the capacity of carbon sinks. Food systems contribute some 20-30% of total global anthropogenic greenhouse gas emissions and their impacts will need to be addressed if substantial global climate change mitigation is to be achieved. In agriculture, management and breeding methods for mitigation of climate change are being developed for all regions. However, not only technological change, but also changes in demand (away from emission intensive foods such as meat and dairy), and in enabling socio-economic structures and the governance framework will influence the amount of GHGs emitted in the future. In the food system, there is scope to develop new practices which deliver multiple win-wins – for example, that function both as climate change adaptation and as mitigation strategies (e.g. climate resilient crops that also bind more carbon in the soil) or that deliver non environmental benefits – for example where shifts to lower environmental impact diets also improve nutritional wellbeing.

This paper calculates country-level mitigation targets for agricultural non-CO2 greenhouse gases (GHGs) based on a variety of allocation methods. This study claims to be the first to calculate national mitigation contributions for the agricultural sector that are consistent with meeting the 2°C target.

This report by the Meridian Institute brings together existing information about climate change impacts and opportunities for climate adaptation and mitigation into a food systems framework.

The Intergovernmental Panel on Climate Change (IPCC) has brought out a handbook to help its scientists communicate climate change issues effectively.

A report by the European Academies’ Science Advisory Council finds that negative emissions technologies (NETs) have ‘limited realistic potential’ and cannot be relied upon to remove carbon at the rate envisaged in the Intergovernmental Panel on Climate Change (IPCC) scenarios for avoiding dangerous climate change.

This paper by researchers in Peru and Spain recognises the as yet uninvestigated potential for developing countries, such as Peru, to mitigate their greenhouse gas (GHG) emissions by changing dietary patterns, given that food represents a high proportion of household expenditure. The study employed Life Cycle Assessment to analyse the impacts of 47 Peruvian diet profiles.

This Research Handbook, edited by Mary Jane Angelo, Fredric G. Levin and Anél Du Plessis, brings together scholars from across disciplines and across the globe (including FCRN member Jonathan Verschuuren) to untangle the climate-food web and critically explore the nexus between climate change, agriculture and law, upon which food security and climate resilient development depends. It is a useful introduction to the research which is being undertaken in the area of climate change and agricultural law.

This paper presents the findings of a food systems model that considers how specific agronomic characteristics of organic agriculture could be harnessed so as to enable it to play a greater role in sustainable food systems.

This new paper by FCRN member Elin Röös , the FCRN’s Tara Garnett and colleagues explores the following questions: What would be the implications, for land use and greenhouse gas emissions, if our global population moved away from eating beef and other ruminant meats and switched mostly to chicken? What if we all went vegan? What if all our meat demand were met by artificial meat? Or what  if, in an attempt to avoid ‘feed-food’ competition, we limited our consumption of animal products to what we could obtain by rearing animals on grasslands and feeding them byproducts and food waste?

This study by FCRN member Helen Harwatt and colleagues seeks to determine whether simple dietary changes can make a meaningful contribution to greenhouse gas (GHG) mitigation efforts, by considering a very simple example of US consumers substituting beans for beef in their diets. The study uses available life cycle assessment (LCA; see Chapter 2 of foodsource) data to predict the change in GHG emissions that would be associated with a substitution of beans for beef (substitution on the basis of calories, and on the basis of protein content). They place these projected changes in the context of US 2020 GHG reduction targets.

In this opinion piece, Edward Parson of the Emmett Institute on Climate Change and the Environment, UCLA, argues that Climate Engineering (CE) must urgently be given greater and more serious consideration within climate change research and policy, and calls upon the IPCC to take responsibility for this.

This OECD Food, Agriculture and Fisheries report employs a meta-analysis/literature review approach to identify and analyse barriers to the adoption of “climate-friendly” policies in agriculture; that is, the adoption of measures to enhance the adaptation of farming to the impacts of climate change, and the mitigation of its contributions to greenhouse gas (GHG) emissions. It should be noted that the report does not go into specifics about what constitutes a climate-friendly practice: this is taken to be an understood concept and the focus of the report is on the barriers to adoption of these measures, not the measures themselves.
