  • E277: Food Fight - from plunder and profit to people and planet

    E277: Food Fight - from plunder and profit to people and planet
    2025/06/27
    Today we're talking with health and nutrition expert Dr. Stuart Gillespie, author of a new book entitled Food Fight: from Plunder and Profit to People and Planet. Using decades of research and insight gathered from around the world, Dr. Gillespie wants to reimagine our global food system and plot a way forward to a sustainable, equitable, and healthy food future - one where our food system isn't making us sick. Certainly not the case now. Over the course of his career, Dr. Gillespie has worked with the UN Standing Committee on Nutrition in Geneva with UNICEF in India and with the International Food Policy Research Institute, known as IFPRI, where he's led initiatives tackling the double burden of malnutrition and agriculture and health research. He holds a PhD in human nutrition from the London School of Hygiene and Tropical Medicine. Interview Summary So, you've really had a global view of the agriculture system, and this is captured in your book. And to give some context to our listeners, in your book, you describe the history of the global food system, how it's evolved into this system, sort of warped, if you will, into a mechanism that creates harm and it destroys more than it produces. That's a pretty bold statement. That it destroys more than it produces, given how much the agriculture around the world does produce. Tell us a bit more if you would. Yes, that statement actually emerged from recent work by the Food Systems Economic Commission. And they costed out the damage or the downstream harms generated by the global food system at around $15 trillion per year, which is 12% of GDP. And that manifests in various ways. Health harms or chronic disease. It also manifests in terms of climate crisis and risks and environmental harms, but also. Poverty of food system workers at the front line, if you like. And it's largely because we have a system that's anachronistic. It's a system that was built in a different time, in a different century for a different purpose. It was really started to come together after the second World War. To mass produce cheap calories to prevent famine, but also through the Green Revolution, as that was picking up with the overproduction of staples to use that strategically through food aid to buffer the West to certain extent from the spread of communism. And over time and over the last 50 years of neoliberal policies we've got a situation where food is less and less viewed as a human right, or a basic need. It's seen as a commodity and the system has become increasingly financialized. And there's a lot of evidence captured by a handful of transnationals, different ones at different points in the system from production to consumption. But in each case, they wield huge amounts of power. And that manifests in various ways. We have, I think a system that's anachronistic The point about it, and the problem we have, is that it's a system revolves around maximizing profit and the most profitable foods and products of those, which are actually the least healthy for us as individuals. And it's not a system that's designed to nourish us. It's a system designed to maximize profit. And we don't have a system that really aims to produce whole foods for people. We have a system that produces raw ingredients for industrial formulations to end up as ultra processed foods. We have a system that produces cattle feed and, and biofuels, and some whole foods. But it, you know, that it's so skewed now, and we see the evidence all around us that it manifests in all sorts of different ways. One in three people on the planet in some way malnourished. We have around 12 million adult deaths a year due to diet related chronic disease. And I followed that from colonial times that, that evolution and the way it operates and the way it moves across the world. And what is especially frightening, I think, is the speed at which this so-called nutrition transition or dietary transition is happening in lower income or middle income countries. We saw this happening over in the US and we saw it happening in the UK where I am. And then in Latin America, and then more Southeast Asia, then South Asia. Now, very much so in Sub-Saharan Africa where there is no regulation really, apart from perhaps South Africa. So that's long answer to your intro question. Let's dive into a couple of things that you brought up. First, the Green Revolution. So that's a term that many of our listeners will know and they'll understand what the Green Revolution is, but not everybody. Would you explain what that was and how it's had these effects throughout the food systems around the world? Yes, I mean around the, let's see, about 1950s, Norman Borlag, who was a crop breeder and his colleagues in Mexico discovered through crop breeding trials, a high yielding dwarf variety. But over time and working with different partners, including well in India as well, with the Swaminathan Foundation. And Swaminathan, for example, managed to ...

  • E276: Climate Change - A little less beef is part of the solution

    E276: Climate Change - A little less beef is part of the solution
    2025/06/20
    Interest and grave concern have been mounting over the impact of agriculture and the food choices we all make on the environment, particularly on climate change. With natural weather disasters occurring much more frequently and serious threats from warming of the atmosphere in general, it's natural to look for places to make change. One person who has thought a lot about this is our guest today, Dr. William Dietz of George Washington University. He's been a prominent voice in this space. Bill, you're one of the people in the field I respect most because our relationship goes back many years. Bill is professor and director of research and policy at the Global Food Institute at George Washington University. But especially pertinent to our discussion today is that Dr. Dietz was co-chair of the Lancet Commission on the global syndemic of obesity, under nutrition and climate change. Today, we'll focus on part of that discussion on beef in particular. Interview Summary Bill, let's start out with a basic question. What in the heck is a syndemic? A syndemic is a word that reflects the interaction of these three pandemics that we're facing. And those are obesity, under nutrition, and we've also called climate change a syndemic insofar as it affects human health. These three pandemics interact at both the biologic and social levels and have a synergistic adverse impact on each other. And they're driven by large scale social forces, which foster clustering and have a disparate impact on marginalized populations. Both in the developed and equally important, in the developing world. Here are a couple of examples of syndemics. So, increased greenhouse gases from high income countries reduce crop yields in the micronutrient content of crops, which in turn contribute to food insecurity and undernutrition in low and middle income countries. And eventually the reduction in crop yields and the micronutrient content of crops is going to affect high income countries. Beef production is a really important driver of the climate change, and we're a major contributor in terms of the US' contribution. And beef production drives both methane and nitrous oxide emissions, and in turn, the consumption of red and processed meat causes obesity, diabetes, colon cancer, and cardiovascular disease. And finally, obesity, stunting and nutrition insecurity occur in the same children and in the same population in low- and middle-income countries. Okay, so we'll come back to beef in a moment, but first, help us understand the importance of agriculture overall and our food choices in changing climate. Well, so I think we have to go back to where this, the increase in mean global surface temperatures began, in about 1950. Those temperatures have climbed in a linear fashion since then. And we're now approaching a key level of increase of 1.5 degrees centigrade. The increase in mean surface temperature is driven by increased greenhouse gases, and the US is particularly culpable in this respect. We're it's second only to China in terms of our greenhouse gas emissions. And on a per capita basis, we're in the top four with China, India, and Brazil and now the US. And in the US, agriculture contributes about 10% of greenhouse gas emissions, and about 30% of fossil fuels are responsible for greenhouse gas emissions. But when you look at the actual contribution of car use among the fossil fuel use, it's pretty close to the contribution of greenhouse gases from agriculture. The important point here is each one degree increase centigrade in air temperatures associated with a 7% increase in water vapor. And this is responsible for the major adverse weather events that we're seeing today in terms of increased frequency and severity of hurricanes, the droughts. And I learned a new term from the New York Times a couple of days ago from the science section, which is atmospheric thirst. I had trouble understanding how climate change would contribute to drought, but that same effect in terms of absorbing moisture that occurs and drives the adverse weather events also dries out the land. So increasingly there's increased need for water use, which is driven by atmospheric thirst. But that increase in air temperature and the increase in water vapor, is what really drives these storms. Because in the Pacific and in the Atlantic and the Gulf of Mexico, this increase in air temperature is associated with an increase in water temperature, which further drives the increase in the severity of these storms. Thanks for that background. Now let's get to beef. You and I were not long ago at the Healthy Eating Research conference. And you gave what I thought was a very compelling talk on beef. We'll talk in a minute about how much beef figures into this overall picture, but first, tell us how beef production affects both climate and health. And you mentioned nitrous oxide and methane, but how does this all work? Cattle production is a big driver of the release of methane. ...

  • E275: Against the Grain - A Plea for Regenerative Ag

    E275: Against the Grain - A Plea for Regenerative Ag
    2025/06/16
    I was at a professional meeting recently and I heard an inspiring and insightful and forward-looking talk by journalist and author Roger Thurow. Roger was a reporter for the Wall Street Journal for 30 years, 20 of them as a foreign correspondent based in Europe and Africa. Roger has written a number of books including one on world hunger and another what I thought was a particularly important book entitled The First 1000 Days, A Crucial Time for Mothers and Children and the World. Now comes a new book on farmers around the world and how they are coping with the unprecedented changes they face. It was hearing about his book that inspired me to invite Mr. Thurow to this podcast and thankfully he accepted. His new book is entitled Against the Grain: How Farmers Around the Globe are transforming Agriculture to Nourish the World and Heal the Planet. Interview Summary I really admire your work and have loved the new book and what I've read before. So, let's talk about something that you speak about: the wisdom of farmers. And you talk about their wisdom in the context of modern agriculture. What do you mean by that? Farmers of the world, particularly the small holder farmers, indigenous farmers, family farmers as we know them in this country, they're really bold and pioneering in what they're doing. And these farmers, kind of around the world as we go on this journey around the world in the book, they've seen their efforts to earn a living and feed nourish their families and communities turn against. So, while conforming to the orthodoxies of modern industrial agriculture practices: the monocropping, the increased use of fertilizers and pesticides and insecticide chemicals, the land expansion, at the expense of savannas, forest wetlands, biodiverse environments. In the face of this, they've really witnessed their lands degrading. Their soils depleting. Their waters dwindling. Their pollinators fleeing. Their biodiversity shrinking and becoming less diverse. Their rains becoming ever more mercurial., Their temperatures ever hotter. And their children and families and their communities becoming ever more hungry and malnourished. So, they've really seen the future of their own impacts on the environment, and then the impacts of changing climates, of more extreme weather conditions. They've really seen this future. They've experienced, lived it, and it's ugly what they see and what they've experienced on their farms. So, that's their wisdom, and they'll really tell us that it doesn't have to be that way if we listen. That such a future isn't inevitable. Because out of their desperation, you know, these farmers have begun farming against the grain. So, there's the title of the book Against the Grain of this modern agriculture orthodoxy to reconcile their roles as both food producers and nourishers of us all, and stewards in the land. They're pushing forward with practices like agroforestry, agroecology, regenerative agriculture, kind of whatever one calls it. Farming with nature instead of bending nature to their will, which is what we too often done and with kind of the larger modern industrial agriculture techniques. So, farming with nature as opposed to against it as they strive to both nourish us all and heal our planet. Give us a sense, if you will, about how important these small farmers are to the world's food supply? So how important are these? They're really important. Extremely vital for the global food chain, certainly for their own families and communities, and their countries. In a lot of places, say in Africa, in many of the countries, on the continent, it's the small holder farmers that are producing the majority of the food. In their communities and in their countries and across the continent. Still not enough. Africa then must become a substantial importer of food. But these small holder farmers are so key and the more success that they have in feeding their communities and families, the more success we all have then in this great goal of ending hunger and malnutrition. Equally important, these farmers are the stewards of the land. And they're on the front lines of these environmental challenges. The threats from the changing climate and more extreme weather conditions. They're the first impacted by it, but they also increasingly see, and that's what stories in the book are about, how they see that their own actions are then impacting their environment and their climates. And this is why they're so important for all of us is that they find themselves at the center of what I think is this great collision of humanities two supreme imperatives. One, nourish the world, so nourish us all. That's the one imperative. And then the other imperative, kind of colliding with that, is to preserve, protect, and heal our planet from the very actions of nourishing us. So, these are these two colliding forces. You know as I think we already know agriculture and land use activities are responsible for about a ...
