A joint project is underway to help countries improve the way they measure, report and verify greenhouse gas emissions from livestock. Each country currently has different methods of measuring, reporting and verifying (known colloquially as ‘MRV’).

The project is divided into four steps:

  1. Characterise international requirements for MRV
  2. Identify the approaches countries are currently taking
  3. Conduct a survey to identify the reasons for these approaches
  4. Make recommendations

It is hoped that a first draft of findings will be published in February 2017.

The joint project is being implemented by the Livestock Research Group of the Global Research Alliance and our Partners CGIAR’s Research Program on Climate Change, Agriculture and Food Security (CCAFS), and the Food & Agriculture Organisation (FAO), with support from UNIQUE Forestry & Land Use, and the New Zealand Government.

In southern Sri Lanka, smallholder farmers grazing their cattle on local coconut plantations have achieved significant improvements in both livestock and coconut productivity by supplementing with Gliricidia sepium and low-cost concentrates, and through strategic manure management.

For three years, the farmers supplemented their cattle’s natural herbage fodder with a high-protein tree fodder crop (G. sepium), a cheap protein source rich in vitamins and minerals; and a low-cost concentrate (comprising urea, rice bran, molasses and minerals). They also restricted the lengths of tethered ropes for grazing, incorporating more dung and urine to the manure circle of the coconut palm; and deposited fallen fronds, coconut husks etc inside the manure circle to promote nutrient recycling.

The impact on animal productivity has been significant, with cows nearly 10% heavier at calving, the first calving age dropping by around 17%, the average birth weight of calves increasing by 13%, and milk yield increasing by up to 47%. Nut and copra yields almost doubled.

These outcomes indicate real potential for improving long-term food security and other environmental gains in the region.

Improved ruminant genetics increase animals’ resilience to climate-related stresses, increases reproductive performance, and – in some countries – could achieve emission reductions of 11-26% per unit of product, according to a new practice brief written by scientists from the Global Research Alliance’s Livestock Research Group and the CCAFS low emissions agriculture flagship. This brief is part of the CSA practice brief series of the Global Alliance for Climate Smart Agriculture (GACSA) Knowledge Action Group.

The brief summarises the state of the science in this area and provides implementation guidance for policymakers and investors. It describes how animal breeding can increase livestock productivity and resilience to climate change, while also reducing greenhouse gas emissions intensity. It focuses on opportunities in developing countries, where the majority of the world’s ruminant populations can be found.

More details on the practice brief can be found in a joint LRG/CCAFS blog post here. You can also download the practice brief here.

Reducing greenhouse gas emissions from livestock: best practice and emerging options’ was jointly published by the GRA’s Livestock Research Group and the Sustainable Agriculture Initiative (SAI) Platform in late 2014. It is now one of the most downloaded documents on the GRA website.

With thanks to funding support from New Zealand and translation provided by LRG members in France, Chile and Colombia, this popular publication is now available in French and Spanish.

The guide is intended to help farmers and industry leaders make progress on meeting global food demand while reducing the industry’s contribution to climate change. It summarises current best practices ready for implementation at the farm level, as well as emerging options at various stages of research to reduce the greenhouse gas emissions intensity of livestock production across a range of farm systems. It covers intervention options for animal feed and nutrition, genetics and breeding, rumen modification, animal health, manure, and grassland management.

WELLINGTON, NEW ZEALAND // BURLINGTON, USA (23 August 2016) – Scientists say that using advanced greenhouse gas inventory and accounting methods to monitor, verify and report on emissions will be necessary for livestock to demonstrate that it is contributing effectively to the ambitious goals of the Paris Agreement on climate change.

Scientists from the Livestock Research Group of the Global Research Alliance on Agricultural Greenhouse Gases (GRA) and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) argue in a newly released brochure that more accurate and robust information on greenhouse emissions and productivity from livestock, captured through an advanced inventory system, will be essential if the sector is to contribute effectively to climate and development outcomes.

“61 nations included mitigation in the livestock sector in their Intended Nationally Determined Contributions submitted to the United Nations Framework Convention on Climate Change in 2015,” Lini Wollenberg, leader of the CCAFS Low Emissions Development research program based at the University of Vermont’s Gund Institute for Ecological Economics, said. “They need advanced greenhouse gas inventories to report on changes in emissions and the reductions in emissions intensity that result from more productive and efficient livestock systems.”

Simple inventory methods (called Tier 1) use livestock numbers multiplied by a constant emission factor per animal, meaning that the only way to reduce emissions from livestock is to reduce animal numbers – not plausible for countries concerned with food security and rural development. Researchers point out that livestock development and climate change outcomes can support each other: more productive and efficient farm systems generally produce food at much lower greenhouse gas emissions per unit of product.

The brochure draws on a global analysis demonstrating that doubling the milk production of low-yielding dairy systems, from 1,500 to 3,000 litres per cow per year, could roughly halve the greenhouse gas emissions per litre of milk from those systems. However, if a country’s livestock greenhouse gas inventory does not use advanced methods (called Tier 2), then the impact of such productivity gains is missed.

Advanced inventories allow countries to understand the impact of different productivity measures on emissions. For example, reductions in emissions intensity may be achieved through (see e.g. here and here):

  • Improved digestibility of feeds
  • Increased pregnancy rates for mature breeding cows
  • Increased weight gains in finishing animals.

Such productivity measures may support rural economic development, form the basis of a climate change mitigation plan to be submitted to the UNFCCC, or help qualify a country for climate finance.

Uruguay, for example, used its advanced greenhouse gas inventory in the livestock sector to commit to reducing emissions intensity in livestock (i.e. emissions per kg of meat) by 31-46% by 2030 from base year 1990. The inventory also allows Uruguay to incorporate outcomes from productivity improvements into its domestic policies and use them to demonstrate progress towards its INDC.

“Many countries know that a Tier 2 inventory would be incredibly helpful for them, but they are deterred by the perceived complexity and the resources required. An inventory based on Tier 2 methods is by its nature more detailed than the simple Tier 1 methods that most countries start out with, but it does not have to be much more complicated,” explained Harry Clark, Co-chair of the GRA’s Livestock Research Group and Director of the New Zealand Agricultural Greenhouse Gas Research Centre.

“Countries need guidance and support on how to set up an inventory that is credible and defensible but does not place unrealistic demands on their data sources,” Clark said.
