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 highlights the lack of inclusion of food consumption in the climate change policy debate. It presents an analysis of how changing from beef to beans could help achieve GHG reduction targets in the US.

This paper takes countries’ mitigation targets (Intended National Determined Contributions, or INDCs), submitted since the Paris Climate agreement, and, using supplementary information from other official documents, quantifies how much of the promised actions are related to Land Use, Land Use Change and Forestry (LULUCF, primarily deforestation and forest management).

This paper by researchers in Germany explores the scalability of managed woody and herbaceous bioenergy plantations (BP) for terrestrial capture of atmospheric carbon. The researchers make simulations to quantitatively explore how much land area could be made available globally for this terrestrial carbon dioxide removal (tCDR) strategy.

Ahead of the third UK election in as many years (8th June 2017), Carbon Brief is tracking the climate change and energy content of parties’ manifestos. The site allows you to navigate around to explore the parties’ climate and energy plans and compare this year’s promises with what the parties said before the last election via a publicly-accessible spreadsheet, which covers both 2015 and 2017.

What is the latest science on soil's ability to pull carbon pollution out of the atmosphere? Breakthrough Strategies hosted a webinar on April 24 on the Technical Potential of Soil Carbon Sequestration. It featured three of the world’s leading experts on strategies for drawing carbon pollution out of the atmosphere and storing it in soils: Keith Paustian, Jean-François Soussana, and Eric Toensmeier.

This report on organic agriculture and climate change was commissioned by the IFOAM-EU Group and researched and written by FiBL (Research Institute of Organic Agriculture). It highlights organic agriculture’s potential to mitigate and adapt to climate change and underlines the importance of adopting a systemic approach - one which encompasses consumption - to reducing all the environmental impacts of agriculture.

This research brings together data from 389 field trials to determine how the root and shoot biomass, and carbon (C) stocks of major crops correlate to soil C in different environmental conditions. The analysis found all crops allocated more C to their shoots than roots. The greatest C allocation to roots was in grasses (which also had the highest plant biomass production).

This paper, published in the journal Science, aims to establish a detailed “roadmap” for meeting the Paris climate goal. It provides not only a scenario for the CO2 emissions reductions needed but places attention on the many different policy actions needed to stay below 2°C warming. One of three main focus areas is agriculture and land use related emissions.

This comment article in The Lancet Planetary Health emphasises that food systems research, addressing sustainability and human health, needs to combine three factors equally to inform comprehensive improvement strategies.

This research links the self-reported Food Frequency Questionnaire (FFQ) data of Swedish participants, to Life Cycle Assessment (LCA) data of carbon footprint for food products. The results of this study indicate that a self-selected diet low in diet related greenhouse gas emissions (GHGE) provides comparable intake of nutrients as a diet high in GHGE, and adheres to dietary guidelines for most nutrients.

In this paper, using three scenarios for food demand, the researchers model and highlight the indirect relationship between greenhouse gas (GHG) emission abatement within the food supply system and the energy system, globally.
