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 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 report, by the US based NRDC (The Natural Resources Defense Council) finds that the per capita diet related carbon footprint of the average US citizen decreased by 10% between 2005 and 2014, driven by a 19% decrease in beef consumption.
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.
This report details the methodology used to create a new online tool which can help companies set science-based emission targets and incorporate land-use change into their mitigation strategies. It is part of the Science Based Targets initiative run by the Carbon Disclosure Project (CDP) CDP, UN Global Compact, the World Resources Institute (WRI) and World Wildlife Fund (WWF).
This paper examines high-resolution, crop-specific GHG emissions and GHG intensity estimates which are derived using a method that couples biophysical models with novel 5-arc-minute resolution data.
This editorial piece in Environmental Research Letters highlights the fact that, as opposed to CO2 emissions, those of the powerful greenhouse gas methane are currently rising faster than at any point in the last twenty years. Around two-thirds of global emissions of methane are attributable to anthropogenic activities, with agriculture and related land use change identified as a main culprit.
In this article co-written by FCRN member Erasmus zu Ermgassen, the authors use what they call a holistic approach (described below) to estimate the GHG emissions savings from preventing UK household food waste. In particular, they include the consideration of a potential rebound effect: the GHG emissions that result from money saved (because of reduced food waste) being spent elsewhere.
One of the greatest challenges of this century is figuring out how to feed more people, while significantly reducing greenhouse gas emissions from agriculture, just as other demands on land - for example, for sequestration and bioenergy production - are increasing.
This report by Zero Carbon Australia, outlines how research on greenhouse gas emissions from land use (agriculture and forestry) can be reduced to zero net emissions, coupled with economic opportunities and increased resilience in the face of climate change. The land use sector is the second largest source of emissions in Australia and is highly exposed to the impacts of climate change. 15% of total emissions in Australia are from the agriculture and forestry sectors, the largest component of which is land clearing for grazing.
This paper by researchers in the US and Australia reports the findings of a long-term field-trial-based investigation into the effect of elevated carbon dioxide concentrations (CO2) on soy yield and drought tolerance. Their findings challenge the widely-held belief that crop yield will be increased by elevated CO2 (the so-called CO2 fertilisation effect) both because of increased photosynthetic rate, and because of lower susceptibility to drought: it has long been assumed that in higher CO2 conditions, stomatal conductance will be lower, leading to slower water loss from the leaves, slower water uptake from the roots, and consequently more moisture remaining in the soil for longer, thereby sustaining crops in limited rainfall.
