Cows Grazing at Sunset

This paper aims to summarize the evidence base concerning carbon storage in pasture land used for livestock production.

Abstract

Approximately a third of all annual greenhouse gas emissions globally are directly or indirectly associated with the food system, and over a half of these are linked to livestock production. In temperate oceanic regions, such as the UK, most meat and dairy is produced in extensive systems based on pasture. There is much interest in the extent to which such grassland may be able to sequester and store more carbon to partially or completely mitigate other greenhouse gas emissions in the system. However, answering this question is difficult due to context-specificity and a complex and sometimes inconsistent evidence base. This paper describes a project that set out to summarize the natural science evidence base relevant to grassland management, grazing livestock and soil carbon storage potential in as policy-neutral terms as possible. It is based on expert appraisal of a systematically assembled evidence base, followed by a wide stakeholders engagement. A series of evidence statements (in the appendix of this paper) are listed and categorized according to the nature of the underlying information, and an annotated bibliography is provided in the electronic supplementary material.

In 2015, the UK pledged to be Net Zero by 2050, with the NFU striving for the more ambitious target of 2040. Net Zero is achieved when the amount of greenhouse gases (GHG) emitted is balanced with those removed from the atmosphere. This helps to combat climate change and reduce global warming.

The UK Government has set a Net Zero target for 2050. Land use and management has a key role to play in this, with the NFU setting an even earlier target of 2040.

Scotland’s Rural College (SRUC) was established in 2012 through the merger of the Scottish Agricultural College (SAC) with Barony, Elmwood and Oatridge Colleges. Through these institutions, we can trace our lineage back over 100 years.

There is a lot of interest in soil carbon currently, due to the opportunity to store and sequester carbon in soil. It is also vital for soil health, forming part of soil organic matter.

The livestock industry is an integral part of the agricultural sector, encompassing various aspects of animal husbandry and production. It plays an important role in global food security and supports the livelihoods of millions of people worldwide.

Climate change threatens our ability to ensure global food security, eradicate poverty and achieve sustainable development. In 2016, 31 percent of global emissions originating from human activity came from agrifood systems.

The key GHGs for agriculture that contribute directly to climate change are:  Carbon dioxide (CO2)  Methane (CH4)  Nitrous oxide (N2O)   All these GHGs are often grouped under the umbrella term ‘carbon’.
