Illuminating a climate-resilient future for pastoralists

Pastoralists—communities who raise livestock in arid and semi-arid lands—are central to food security in Kenya and much of Africa. They practice transhumance, moving herds seasonally between grazing areas to match forage availability, and employ extensive knowledge of variable landscapes to thrive where others struggle. Their mobility, social networks, and deep environmental understanding make them incredibly resilient. Pastoral communities supply large shares of milk and meat in regions where farming is nearly impossible.

Pastoralism covers more than half of the Earth’s land surface, supporting hundreds of millions of people, especially across Africa and Asia, in areas where conventional farming doesn’t work. In Africa alone, the African Union estimates that pastoralism contributes between 10% and 44% of national GDP in pastoralist-reliant countries—underlining its economic significance and the structural risks of sidelining these communities.

But their way of life is under increasing threat. Worsening droughts, shrinking access to water and grazing land, and competition over scarce resources have made it harder to sustain herds. Many pastoralists, especially the younger generation, are leaving behind livestock herding for other livelihoods, but these alternatives are often limited, insecure, or inaccessible to the poorest. As one pastoralist put it starkly: “The future for pastoralists is dark unless something is done.”

A new study published in Ecology and Society, led by Elizabeth Fox (now at Cornell), who at the time was a postdoc in my group, in collaboration with colleagues in Kenya, worked with Borana and Turkana communities in Isiolo County, Kenya, using photos and interviews to capture pastoralists’ own perspectives on what’s happening. People described how climate change has eroded traditional coping strategies, such as moving with herds or relying on community networks. Land once shared is now fenced off for farming, conservation, or settlement. Traditional authority structures have weakened, and political representation remains limited. Many participants felt neglected by leaders and frustrated by top-down programs that provide mismatched support—like giving seeds when there’s no water. Some have turned to short-term survival strategies such as charcoal burning, which are environmentally destructive and unsustainable.

Below shows the story of pastoralists – through their eyes – using photo elicitation in which pastoralists were given cameras, asked to take pictures about the “story of pastoralism” and then select the photographs that were most salient to them. They chose the titles and descriptions of each photograph.

Yet, pastoralists also identified opportunities for a more hopeful future (see table below). They pointed to the need for practical interventions: better veterinary care and water infrastructure, land rights and grazing corridors, fair livestock markets, training for value-added businesses, and education that creates diverse job opportunities without abandoning pastoral traditions. Most importantly, they emphasized being included in decisions about their future. The takeaway is clear: pastoralists already know what they need. The challenge is for governments and development partners to listen, invest in equity, and support solutions that allow pastoralist communities to thrive while adapting to climate change. Without this, not only pastoralists but also the broader food systems they sustain stand to lose.

This pastoral way of life is vulnerable unless safeguarded. Policies that restrict mobility, privatize grazing lands, or ignore pastoral voices threaten not only their survival—but the broader ecological balance they help maintain. Supporting pastoralists with secure grazing corridors, recognition of communal rights, and adaptive governance isn’t charity—it’s an act of stewardship for resilient, sustainable futures.

Food Bytes: April 2025 Edition

FOOD BYTES IS A (ALMOST) MONTHLY BLOG POST OF “NIBBLES” ON ALL THINGS CLIMATE, FOOD, NUTRITION SCIENCE, POLICY, AND CULTURE.

It’s getting harder these days to cut through the noise we see every day in the news — and even harder to stay positive. I feel it too, my friends. I hear you.

But despite how surreal the world feels, it keeps turning — and so must science.

This past weekend, I had the honor of being inducted into the National Academy of Sciences (NAS) at their annual meeting. As I watched 120 brilliant scientists receive this honor, I was struck by something simple but powerful: there are still so many good people out there, working tirelessly to make the world a better place.

Even as we face growing threats against scientific endeavors, moments like this remind me how lucky I am to do the work I do. And more than that, they strengthen my resolve: I will fight for the ability to do science — not just for myself, but for future generations who will carry this work forward.

In this month’s Food Bytes, I’ll be sharing a roundup of some of the media I've been reading. There’s a lot to filter through these days. Next month, I’ll be shifting my focus entirely to peer-reviewed articles, because some truly outstanding science is being produced, even in these turbulent times. Stay tuned.

Speaking of the shenanigans happening in the U.S., some colleagues who work on international nutrition discuss the impact of cutting international food aid. Devastating. Love this piece by Jody Harris on how the stop to U.S. food security funding is an assault on justice. Tom Philpott also writes about how this notion of “Make America Healthy Again” is poisoning the food movement. Feeling paranoid? Maybe start thinking about your apocalyptic emergency food kit. According to Food & Wine, the new U.S. dietary guidelines have you covered. Yah, right. Oh, and restaurants that the middle class can afford? Gone. As I said, get that food kit ready.

The climate is always front and center. The state of the climate report is out. Pretty dismal read. The COP30 will be in Brazil this year. This BBC article claims that some of the Amazon forest was cut down to build the highway to where the COP meeting will take place. Yikes. Speaking of COP30, it seems food is less on the agenda. What a shame. And more and more, we are seeing calls to better integrate nutrition and climate. Couldn’t agree more, but we need more and better evidence. Check out our new paper on the links between climate and nutrition.

Effects of climate change and extreme weather events on various systems that influence nutrition outcomes (Fanzo et al 2025)

According to this article, America can’t quit soda. Yet this Vox one claims we are dairy milk guzzlers. Whichever it is, it seems Americans loooove red meat and the current politics are making that all the easier. Even though some argue that eating less meat is one of the most important things individuals can do to impact the planet, and tech is doing its best to make plant-based foods, including eggs. But tech won’t save us. We need to understand better how we value food systems.

And as Wendell Berry said, eating is an agricultural act. How we manage agriculture and who manages it will dictate our future, but there is still much disagreement on how to manage it. The great Kenn Giller discusses how fractious and contentious future agriculture conversations can be on the Table Debates podcast. The CGIAR, a large conglomerate of research centers dedicated to improving agriculture worldwide, has launched a new research portfolio.  Speaking of agriculture, some other enjoyable listens, views, and reads:

  • The rise and fall of Quinoa on Jeremy Cherfa’s Eat This Podcast.

  • The role of Phosphorus in agriculture. One word: Essential!

  • Rice is making a comeback with black farmers.

  • Goats, the heroes in every story, are empowering women around the world. Of course they are!

  • Philanthropists are not helping African farmers, according to The Guardian.

  • The mafia is goin’ down at least when it comes to food fraud. Bada bing!

Things I look forward to:

That’s it for April folks. See you in May!
