As the world gathers in Brazil for the UN climate talks, the country’s livestock sector – one of the largest in the world – is understandably in the spotlight.

Livestock are a significant contributor of greenhouse gas emissions in Brazil (and around the world) and have been linked to deforestation, but these animals represent so much more than that to so many, especially in the Global South.

Brazil accounts for approximately 20 per cent of global beef exports. The livestock sector is a major contributor to the country’s economy – responsible for 8.4 per cent of gross domestic product (GDP) and roughly nine million jobs.

For 1.3 billion people worldwide, livestock is a lifeline: a protector of livelihoods, guardian of nutrition, cornerstone of tradition, and potential pathway out of poverty. For the majority and especially pastoralists, reducing herd sizes is not an easy, or frankly viable, option.

COP30 is supposed to bring people from vastly different contexts together, to find solutions that work for everyone, as well as funding to enable it to happen. This year’s host offers special lessons for Africa’s livestock sector, as Brazil’s livestock sector was not always so productive and efficient.

Brazilian policies and investments have seen livestock productivity rise 61 per cent in the past two decades, while pasture land use and emissions intensity – that is, the emissions per unit of meat, milk or eggs produced – have gone down.

The key to this success has been avoiding uniform prescriptions and instead adopting regionally adapted and context-specific approaches.

For example, high-yield tropical grasses like Brachiaria have become central to boosting productivity across the country’s Cerrado region, improving cattle health and overall performance, and reducing costs. In southern Brazil, where smaller farms are more common, the integration of crop-livestock systems have increased land efficiency, promoted biodiversity, and diversified farm incomes. Mineral supplements and high-energy feeds have had the biggest impact in the Southeast of Brazil, where there are large feedlots.

Much like Brazil thirty years ago, many of today’s developing countries struggle to produce meat, milk and eggs efficiently. Poor quality feed, animal health, and genetics mean animals take much longer to reach slaughter weight or milk volume. Even if herd sizes are smaller, the emissions per unit of product can be 16 times higher.

The impact is that hunger and poverty are prevalent in these countries and, in some, still rising. Micronutrient deficiency – a result of insufficient animal-source food consumption – is also widespread among children, which has a devastating effect on health and economic development (contributing to annual GDP losses up to 16 per cent).

This is why at the International Livestock Research Institute (ILRI) we are researching science-based interventions that raise productivity and cut emissions intensity. For example, MaziwaPlus is an animal health-oriented project focused on Mastitis, a disease in dairy cows responsible for milk yield losses of up to 25 per cent. With Scotland’s Rural College we are also working on highly digestible forages, which could result in 20 per cent methane emissions reductions. EnviroCow is another productivity-oriented initiative, trying to identify livestock that remain productive despite environmental challenges.

And ILRI’s work does not stop at research. The Institute also connects evidence with policy and practice, as seen in Kenya’s recent submission to the UNFCCC’s Sharm el-Sheikh portal, which cites participatory rangeland management approaches developed by ILRI and partners.

Unlocking these benefits at the global level will require reframing the worldwide sustainability discussion around livestock – seeing it as a solution to be invested in, rather than a problem to be swept under the rug.

For example, climate finance should start rewarding reductions in emissions intensity (not just absolute emissions), so that countries improving productivity and lowering emissions per litre of milk or kilo of meat are supported. Moreover, the world needs to invest far more than the 0.2 per cent of climate finance currently put towards livestock research and innovation (and even less to developing solutions in low- and middle-income countries).

Most importantly, livestock should be embedded in national climate plans. Livestock should be recognised as more than a source of emissions, and as an important solution for climate resilience, food security, and adaptation – especially in developing countries and regions where they are the backbone of rural economies.

But as COP30 concludes, the conversation cannot end there.

This year’s conference must be a moment when the world recognises that livestock, managed well, are an important part of a more pragmatic global strategy which both protects the planet and raises the welfare of its people.

The timing could not be more fitting as next year will begin the UN-declared International Year of Rangelands and Pastoralists. Rangelands cover over half of the Earth’s land surface, store vast amounts of carbon, and support hundreds of millions of pastoralist livestock keepers, yet barely feature in most national climate plans.

If we choose to recognise and act on the potential of rangelands and pastoralists, they can become one of the great success stories of climate and development – driven by science, stewardship, and local knowledge.

One would expect that this year’s wetter than average rainy season in parts of Africa would be viewed with relief, not fear. Yet many areas in the region sits at a knife’s edge—still recovering from years of drought and a historic famine, too much rain leads to flooding and water-borne diseases. Both varieties of extreme weather place enormous stress on livestock systems across the region, on which communities rely for both sustenance and livelihoods.

Despite this, current planning around climate change tend to focus narrowly on weather patterns, overlooking the impacts on animal agriculture. Even with strong evidence that healthy animals support livelihoods while helping to reduce climate impacts, just 20 out of 176 countries mentioned animal health and welfare in their latest climate commitments (NDCs). African nations cannot afford to make this omission.

Animal health isn’t just a veterinary concern – it’s a global public good.

Climate change accelerates these threats by changing animal disease patterns: warmer temperatures, shifting rainfall, and extreme weather events create new environments where diseases can spread more easily, jump between species, and appear in places they never did before. These challenges hit especially hard in Africa, where smallholder farmers rely on livestock for survival, and where animal illness can mean lost income, food insecurity, and greater vulnerability to climate shocks.

Governments must prioritise animal health as a matter of urgency. And there are plenty of reasons for them to do so.

Healthy animals are good news for the climate. Research shows that smart animal health and husbandry practices can reduce climate-warming emissions from livestock by up to 30 percent. They’re also more resilient to the effects of climate change which include more frequent and more intense heatwaves, droughts, and disease outbreaks.

Fortunately, prevention is incredibly cost effective. Investing in measures to prevent zoonotic spillover would cost less than 5 percent of the damages those diseases could inflict on society.

Healthy animals underpin prosperous communities and nations. In Africa, livestock are a major source of income and nutrition for the large majority of people living in poverty. The good news is that we know what we need to do to keep our animals healthy and well. We need to support them with balanced diets, quality veterinary care, robust disease monitoring and control, and good husbandry practices. These are all proven, affordable, and scalable strategies.

Vaccination is essential to any effective animal health strategy. Safe, effective vaccines curb the occurrence and spread of diseases, reduce the need for antimicrobials, and boost productivity sustainably. Backed by science, vaccines are among the most cost-effective tools we have for keeping communities across Africa and the rest of the world safe and healthy, all while meeting animal health and welfare goals and building climate-resilient food systems.

Forward-thinking African nations are leading the way by adopting a One Health approach, which acknowledges that human, animal, and environmental health are deeply intertwined. Countries like Botswana, Côte d’Ivoire, Kenya, Namibia, Tanzania and Zambia are moving away from fragmented, sector-specific responses in managing the health of humans, animals and the environment.

In Kenya, for example, the government has integrated One Health principles into national policy by fostering collaborations between agriculture, health, and environment ministries. Kenya’s multi-sector Zoonotic Disease Unit has helped to detect and control outbreaks of diseases like Rift Valley fever and anthrax – before they have had the chance to escalate.

In Côte d’Ivoire, a One Health initiative brought together experts in wildlife, veterinary health and public health to boost the surveillance and management of wildlife diseases, an important challenge in the country.

Some argue that the future of food should move away from animal-based systems altogether. But in many African countries, livestock remain indispensable as a main source of protein – especially in areas where an annual harvest isn’t guaranteed, or on arid lands, where growing crops isn’t feasible. The solution isn’t to abandon livestock; it’s to support farmers to keep their animals healthy.

The climate problems are not confined to the Horn of Africa. As governments across the continent look to raise the ambition of their climate commitments, leaders must seize the opportunity to elevate animal health as a national priority and integrate it as a critical component of their national climate action plans (NDCs).

The message is clear: It’s time to recognize healthy animals as essential for both climate change mitigation and sustainable development.

Africa is contending with a climate crisis it did not create without sufficient recognition for the unique rights and needs of the world’s youngest and fastest-growing population. Not only is the continent least responsible for reducing greenhouse gas emissions, having historically produced just a tiny fraction, but it is also disproportionately impacted by the consequences of emissions generated elsewhere.

And when climate disasters such as cyclones in Mozambique and Malawi, or droughts in the Horn of Africa strike, the subsequent humanitarian response diverts vital funds that could have otherwise supported public health, education and food security.

Such extreme events take an enormous toll on Africa’s primary industries, including crop and animal agriculture, with the livestock sector alone losing $2 billion from the ongoing drought.

It would therefore be preposterous to hold any of these sectors directly to account for curbing climate change – let alone one that provides food and livelihoods for hundreds of millions amidst growing climate risks.

Yet this is precisely the scenario that unfolds when the global climate debate around the role of livestock results in calls for blanket reductions of herd numbers and wholesale dietary shifts away from meat.

Broad campaigns for a transition away from animal agriculture and towards plant-based diets without qualifying regional differences overlook the severe levels of undernutrition in parts of the world caused by inadequate intake of animal-source foods. This risks creating the impression that Africans, who consume as little as seven kilograms of meat a year, must give up vital yet underconsumed sources of protein and micronutrients to mitigate emissions mostly generated elsewhere.

It is critical that regional and even national distinctions are made when making the case for dietary and production changes. Meat consumption and production practices vary enormously around the world. Where meat is over-consumed and produced unsustainably, we recognise this needs to change – not only to bring down emissions but to improve health standards.

But applying this argument globally misses the livestock sector’s outsized and fundamental role in the development of low-income countries, including those across Africa. And this blind spot is made all the more unjust by the fact that those in the Global North have both driven up global emissions and failed to meet commitments to Africa for climate-related development finance.

Livestock keeping offers African countries a gateway to the food security and economic growth enjoyed elsewhere while also enabling the climate adaptation made necessary largely by the actions of others. Investing more climate funding to support Africans farmers and animals adapt to new extremes is an enormous opportunity for a climate-resilient economy. And it is also a matter of climate justice.

Unlike many other parts of the world, Africa is facing exponentially more mouths to feed in the decades ahead just as climate change makes farming harder and riskier than ever.

By 2050, a quarter of the global population will be African, while the region already suffers from the highest prevalence of hunger and malnutrition in the world. From 2021 to 2022, an additional 11 million Africans faced hunger, with 57 million more slipping into food insecurity since the Covid-19 outbreak began.

For many Africans, meat, milk and eggs are a precious and infrequent addition to our diets, providing a dense supply of nutrients and energy that are not as readily available from other foods or supplements.

Africa’s rising population is also an increasingly youthful population, and the majority of young people in sub-Saharan Africa already work in agriculture and in rural areas. Livestock will remain fundamental to Africa’s economic development, contributing up to 80 per cent of agricultural GDP.

As the sector adapts to new demands and circumstances, it also has the opportunity to develop differently to the livestock sector in industrialised countries. At present, half of Africa’s meat and milk is produced by pastoralists, whose animals roam and graze, providing valuable services for natural ecosystems and biodiversity.

However, changes in drought cycles are resulting in shortages of animal feed and fodder, which leads to food and economic insecurity, instability and even conflict among rural communities.

Solutions already exist in Africa that allow rural communities to continue to benefit from raising livestock in spite of climate extremes. These include more climate resilient indigenous cattle breeds and varieties of livestock forages, better climate information services, training and services for farmers and more sophisticated infrastructure and markets. Moreover, these innovations also help to make African livestock systems more efficient, meaning less loss and waste, and lower levels of emissions.

But the continent urgently needs more climate finance to help the entire livestock sector access these new developments. Africa needs to be able to realise the full potential of its livestock sector as a driver for development, and this has been recognised by the African Union in its Agenda 2063 as well as the Comprehensive Africa Agriculture Development Programme (CAADP) and the Livestock Development Strategy for Africa (LiDeSA).

For the most part, the continent does not contend with the same overconsumption, industrialisation and carbon footprints that drive the agenda in the Global North. Because of this, the opportunities that livestock present for Africa should be fully recognised – and fully funded.
