“…Henderson et al (2017a) [38] derived a global marginal cost schedule for livestock abatement options, finding that optimal strategies vary regionally. Regarding land-based options, the authors projected that improved grazing management would be particularly cost effective in Latin America and Sub-Saharan Africa, while legume sowing on pastureland would work best in Western Europe and Latin America.…”

“…Caro et al (2016) [46] estimated that, by adding lipids into ruminant diets, the enteric CH 4 emissions can drop by 15.7%. Also, Henderson et al (2017a) [38] found that treating crop byproducts with urea can mitigate CO 2 , N 2 O and CH 4 emissions and using feed dietary lipids and nitrates can reduce enteric CH 4 emissions.…”

Abstract:The livestock sector is vulnerable to climate change and related policy in two ways. First, livestock production and performance are directly impacted by climate with many projected effects being negative. Second, the sector may need to alter operations to limit the effects of climate change through adaptation and mitigation. Potential adaptation strategies involve land use decisions, animal feeding changes, genetic manipulation and alterations in species and/or breeds. In terms of mitigation, livestock is a substantial contributor to global non-CO 2 greenhouse gas emissions. Mitigation opportunities involve altered land use for grazing and feed production, feeding practices, manure treatment and herd size reduction. In addition, strengthening institutions that promote markets and trade, as well as local support programs can help both mitigation and adaptation. Previous literature has summarized the options available to individual producers. This overview extends the literature by including sector-level response as well as the relationships between adaptation and mitigation activities.

“…Work to develop methods for quantifying nutrient use efficiency is underway (see Powell et al, 2013). The Global Livestock Environmental Assessment Model is a potentially powerful tool for predictive modelling, for example, for quantifying the impact of GHG mitigation measures (Henderson et al, 2017), but fully realizing this potential will require development of some of the formulae and improved data quality.…”

The livestock sector is one of the fastest growing subsectors of the agricultural economy and, while it makes a major contribution to global food supply and economic development, it also consumes significant amounts of natural resources and alters the environment. In order to improve our understanding of the global environmental impact of livestock supply chains, the Food and Agriculture Organization of the United Nations has developed the Global Livestock Environmental Assessment Model (GLEAM). The purpose of this paper is to provide a review of GLEAM. Specifically, it explains the model architecture, methods and functionality, that is the types of analysis that the model can perform. The model focuses primarily on the quantification of greenhouse gases emissions arising from the production of the 11 main livestock commodities. The model inputs and outputs are managed and produced as raster data sets, with spatial resolution of 0.05 decimal degrees. The Global Livestock Environmental Assessment Model v1.0 consists of five distinct modules: (a) the Herd Module; (b) the Manure Module; (c) the Feed Module; (d) the System Module; (e) the Allocation Module. In terms of the modelling approach, GLEAM has several advantages. For example spatial information on livestock distributions and crops yields enables rations to be derived that reflect the local availability of feed resources in developing countries. The Global Livestock Environmental Assessment Model also contains a herd model that enables livestock statistics to be disaggregated and variation in livestock performance and management to be captured. Priorities for future development of GLEAM include: improving data quality and the methods used to perform emissions calculations; extending the scope of the model to include selected additional environmental impacts and to enable predictive modelling; and improving the utility of GLEAM output.

“…Although grazing livestock contribute significantly to GHG emissions, it is feasible to make livestock production systems part of the mitigation solution by changing management. Improved forage quality and feeding practices can help mitigate GHG emissions (Sirohi, ), but the effectiveness of improved management will depend on locating areas where these practices will work (Henderson et al, ). For example, Thornton and Herrero () showed that a 10% improvement in digestibility of stover and increasing grain supplement from 0.5 to 2 kg per head per day both effectively reduced CH 4 emission in cattle.…”

Grasslands are the predominant forage source for grazing animals and cover more of the Earth's land than any other major vegetation type. Their values are not always recognised, and conversion to other uses is continuing at a high rate leading to greater environmental and socio‐economic problems. Overgrazing is one of the main drivers of productivity decline of grasslands, reflecting the pressures from excessive human populations and a demand for food. Some 20% of the world's grasslands are in a severely degraded state; others have suffered shifts to less‐desirable species. Biodiversity and greenhouse gas production have also been particular concerns. Estimates of productivity change all show a decline over recent decades, yet animal numbers continue to increase, particularly in the developing world. This paper critically reviews the projected demands for livestock products, driven largely by human population growth; the current health of the world's grasslands and how current livestock systems that depend on land conversion and overexploitation of grassland are inappropriate and need to be improved. Central to this argument is that small holders in the developing world will be responsible for a large amount of the future red meat production, and this can be achieved through more efficient livestock production systems using lower stocking rates. The Australian sheep industry is provided as an example of how livestock production and reduced environmental impacts can be achieved with improved efficiency. Changes will require smallholders to transition to a competitive, market‐oriented livestock industry, which will provide challenges.
