NAIROBI, Kenya, Nov 14 2025 – 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.
