Introduction This briefing paper will argue that modern industrial intensive livestock production methods need to be understood as significant producers of anthropogenic climate change emissions. Any efforts to mitigate such emissions need to address the structure of the current food system. In addition, there are pressing public policy issues of food security, ethics, human health and concerns over habitat destruction and loss of biodiversity, all which require policy Intervention and reform.
The Central Role of Livestock Agriculture in Anthropogenic Emissions The UN Food & Agriculture Organisation estimates that the livestock sector is responsible for 14.5% of human produced anthropogenic emissions(1). The volume of emissions is set to rise with increasing intensification of livestock production (2). Studies show that it is unlikely that global temperature increases can be contained below 2 deg C without changes in global meat and dairy consumption. (3). Increasingly, the negative consequences of industrialised livestock production on food security, economic development, health and social justice are being understood, and resulting in calls for reform of the sector(4).
Major trends in modern agriculture Modern industrialised livestock systems differ materially from traditional farming methods(5). Production processes are undergoing structural shifts, from rural to peri-urban areas, from extensive grazing to intensive confinement grain-fed operations, from smaller scale privately owned farms to large corporatised operations, as well as a move towards monogastric species (mainly pigs and chickens) in favour over ruminants (cows and sheep)(6). These processes are often believed to be necessary for global food security. Yet studies show that smallholder farms still produce over 70% of the world’s food off only 20% of the world’s arable land(7). Livestock systems produce 33% of the proteins in human diets, but there is a strong and positive relationship between the level of income and theconsumption of animal protein (8) - factory farming is not necessary to feed the worlds poor.
Negative Outcomes Increasingly, the negative consequences of intensive livestock operations are being understood, namely:
i. When livestock are raised in intensive systems, they convert carbohydrates and protein that might otherwise be eaten directly by humans and use them to produce a smaller quantity of energy and protein. In these situations, livestock can be said to reduce the food balance(9);
ii. The food sector accounts for approximately 30% of global energy consumption. There is justifiable concern that the current dependence on fossil fuels may limit the sectors ability to meet global food demands(10).
iii. The livestock sector is the largest sectoral source of water pollution, contributing to eutrophication,dead zones in coastal areas, degradation of coral reefs. The sources of pollution are from animalwaste, antibiotics and hormones, fertilizers and pesticides from feedcrops and sediments fromeroded pastures(11).
iv. With over half the world’s annual antibiotic production being fed prophylactically to farm animals,antimicrobial resistance (AMR) is an increasingly serious threat to global public health. A postantibioticera - in which common infections and minor injuries can kill - is a very real possibility forthe 21st century(12).
v. The production of soy for animal feed is a key factor driving deforestation in South America,entailing massive biodiversity loss(13). The livestock sector is the major driver of deforestation, as wellas being one of the leading drivers of land degradation, pollution, climate change, overfishing,coastal area sedimentation, wildlife conflicts, and the facilitation of alien species invasions. Some306 of 825 terrestrial eco-regions reported livestock as a current threat. 23 of 35 ConservationInternational biodiversity hotspots reported livestock as a current threat(14). Deforestation is asignificant climate change concern.
vi. The explosion in farm animal numbers, along with the geographical concentration of large scalepoultry and pig production, and the transport of animals over long distances, facilitates theemergence of new strains of influenza viruses that can give rise to human pandemics(15).
vii. Between 850 million and 1 billion people do not have enough good quality food to eat, i.e. they aremal- or undernourished. Yet, 1.5 billion are classified as overweight, with 30% of these beingclinically obese(16). The failures of the current global food system to ensure adequate nutrition of foodsecurity are obvious.There are growing inequalities in the scale of production units in all regions of the world, withincreased concentration in larger industrialised production systems. Small family producers aremarginalised and disadvantaged. Land ownership is becoming more concentrated with economicand political elites in wealthy countries even buying land for speculative purposes. People of colour,who may be the ethnic majority where the land is located, are further excluded from access to landfor the production of food that can be consumed locally or regionally. This differentially impactswomen farmers, who are the majority of the small agricultural producers worldwide(17). With afundamental shift in the functions of livestock, there is a significant danger that the poor are beingcrowded out and global food security and safety compromised(18).
viii. The welfare of animals raised in intensive confinement feeding operations has been recognized asone of the most pressing ethical challenges of our time(19), and many institutionalized practices areincompatible with modern moral standards. The most egregious forms of cruelty (confinement,mutilation etc.) are progressively being outlawed, with increasingly widespread calls for moresustainable, ethically defensible farming methodologies.
Policy Recommendations. The UN has identified many of the interventions required, and these are set out extensively in the Interim report of the Special Rapporteur on the right to food, presented to the UN General Assembly on 5 August 2015. These include recognition that:
1. Climate change and food policy are complicated inter-related fields. Hunger and malnutrition are a function of social and economic problems, not production(20). Food security and adaption to climate change are mutually supportive policy outcomes(21), and policy makers thus need to consider the issues together.
2. The trend towards intensive industrialised livestock production needs to be arrested and reversed, to reduce the impact of the sector on the environment generally, and on anthropogenic emissions in particular, and to improve food security, economic development, social justice and ethics. There is a need to encourage a major shift from current industrial agriculture to transformative activities such as conservation agriculture (agroecology) that support the local food movement, protect smallholder farmers, empower women, respect food democracy, maintain environmental sustainability and facilitate a healthy diet(22).
3. The pivotal roles in food production of smallholder farmers, women and indigenous and local communities must be recognized and protected and their acute vulnerability to climate change acknowledged(23).
