More than a third of all crops worldwide end up in the stomachs of livestock. That includes one billion tonnes a year of soybeans and maize alone. The feed and livestock industries want to increase that even further.

Livestock’s share of global greenhouse gas emissions is understated. The climate footprint of the animals and the feed they need is significant. There are ways to change that.

Pesticide applications are on the rise across the globe. Some of the most dangerous substances have been banned in the European Union, but are still being used on a large scale in other parts of the world. Many are intended for the cultivation of soybean and maize, which are destined mainly for use as livestock feed.

All animal products have a water footprint: the amount of water needed to produce them. It is not just the total amount that is important, but the types of water that are needed. There is enough “green” water. But the volumes of “blue” and “grey” water should be kept low.

Nitrogen pollution from livestock manure is an increasing problem in many parts of the world. Countries in the European Union have lots of ideas on how to reduce such contamination of their environments. One approach is through closer monitoring of industrial livestock producers and restricting the amount of manure slurry that crop farmers are allowed to apply.

Across the globe, peatlands are being drained for farming and raising livestock. But dried-out peat emits huge amounts of greenhouse gases. Agricultural policy should initiate the transformation to the climate-friendly use of these areas.

Antibiotics help to treat many diseases. The big problem: in both humans and animals, pathogens can develop antibiotic resistance – a fatal danger. And in industrial livestock production, these drugs are still not being used carefully enough.

Livestock production and meat consumption stimulate outbreaks of diseases that can be transmitted from wild animals to humans. Such zoonoses can have catastrophic consequences – as Covid-19 has shown.

Mobile herders move with their herds or flocks in the remotest of pastures. This form of animal production, known as pastoralism, is economically important and climate-friendly, but it is under severe threat.

India is the world’s largest exporter of buffalo, sheep and goat meat. Remarkably, the majority of this output is produced in traditional agropastoral systems.
