Rice feeds more people than any other crop, and it is grown in a way that is quietly expensive. Globally, a third of all groundwater extraction goes to rice farming. And because those fields sit flooded for weeks at a time, the resulting anaerobic conditions produce methane. Rice accounts for around 2% of global greenhouse gas emissions, comparable to the aviation industry, and about 12% of all me...

Managing and mitigating risk runs through my whole conversation with Robert Bonnie. Since the Dust Bowl, USDA policy, the Farm Bill and especially crop insurance have given US farmers a safety net that shares the risk of growing the nation's food. But farming keeps getting riskier. Climate change, volatile input costs and commodity prices, access to labour, access to markets and geopolitical...

Beef sustainability frequently gets framed as something imposed on the ranchers and the industry from outside—regulatory requirements, consumer pressure, climate obligations driven by environmental groups and activists, leaving the industry industry to respond or resist. But this frame misses something fundamental. My guest today, Tom McDonald, is chair of the U.S. Roundtable for Sustainable Beef...

The beef industry has spent decades optimizing feed efficiency in one place: the feedlot. Genetics have been selected for finishing performance, cattle are placed on feed at lighter weights and fed to heavier carcasses, and the result is measurable improvement in how much feed converts to pounds of beef. Al Rotz's 50-year life cycle assessment comparing 1972 to 2022 documents this clearly—the...

Meat consumption has risen every single year that the United Nations Food and Agriculture Organization has been measuring. Despite warnings about climate impacts spanning over a century, from carbon and methane's  effects to James Hansen's congressional testimony in 1986, to a book called "Diet for a Small Planet" published 52 years ago, global meat production continues its upw...

Forty leading global food and agriculture companies recently declared their commitment to regenerative agriculture. This unprecedented industry alignment signals that the sector has moved beyond looking at sustainable farming an aspirational ideal and into investment and scale. Yet challenges remain as adoption of regenerative practices is sliding backward in North America. Satellite imagery proce...

The poultry and swine industries have transformed feed efficiency over the past two decades. Through systematic improvement in nutrition, enzyme utilization, and animal genetics, they now produce vastly more protein from  fewer resources.  The challenge is not simply reducing methane emissions from cows, but reducing methane per unit of milk produced while maintaining farmer profitability and food...

Artificial intelligence is advancing at an astonishing pace—improvements measured in five-thousand-fold increases from week to week according to AI researchers at Singularity University. Yet in agriculture, most farmers remain largely disconnected from these advances, using AI only at the most basic level for administrative tasks like finance, report writing, and form filling. This widening gap th...

“I’m yet to meet a grazier that doesn’t want a 5-15% feed conversation ratio improvement.” says Tom Williams, CEO of Number 8 Bio.  Producers motivated by not losing 10% of their feed to the atmosphere. Enteric methane from livestock represents one of the rare climate challenges where environmental impact aligns with economic opportunity. Methane is a potent greenhouse gas and  it also represents...

The green revolution resulted in unprecedented improvements in the efficiency and productivity of food production. Recent decades of increasingly globalized free trade has further imporved efficiecies across the supply chain. These improvements that have benefited millions have done so largely at the expense of resiliance and the shock waves of this vulnerability are starting to be felt as fertili...

The journey toward sustainable beef production in the United States began before the term "sustainability" entered common usage.  Today we are joined by Steve Wooten, a rancher in southeastern Colorado's shortgrass prairie and a founding member of the U.S. Roundtable for Sustainable Beef. Wooten manages Beatty Canyon Ranch in a region receiving 11-14 inches of annual rainfall, where...

Feed efficiency remains one of the biggest gray areas and least understood aspects of livestock production. Yet understanding how much grass a cow consumes to produce a calf or a ewe to produce a lamb is critical not only to farmer and ranch profitability, but also to the sustainability of the industry. At 19 cents per kilogram to grow dry matter, inefficiency compounds rapidly. The difference bet...

Feed efficiency, despite its importance from both an environmental sustainability and farm profitability perspective, remains one of the biggest gray areas and least understood aspects of livestock production. Today we are joined by Matt Wilson from West Virginia University, who has spent his career studying how efficiently cattle convert grass into food. In 2003, Wilson installed the first indivi...

There is a huge amount we can learn from understanding the connections between soil health, food production, and human metabolic health. Over the last 50-60 years, modern agricultural systems have become increasingly reliant on synthetic inputs that boost yields but degrade soil microbiomes and reduce micronutrient density in our food. This degradation contributes to the chronic disease epidemic c...

Currently beef cattle production faces a profitability challenge driven by rising feed costs and efficiency gaps. For cow-calf operations, particularly where producers operate on forage-based systems, the biggest variable cost is cow feed, yet geneticists lack precise selection tools for measuring and improving forage intake and conversion efficiency.  Today we are joined by Troy Rowan from the Un...

Over the last century our food systems have become increasingly reliant on synthetic nitrogen. This nitrogen fertilizer is mostly made through the energy intensive haber-bosch process in centralized production plants, often located in politically sensitive location, that have a carbon footprint multiple times greater than the aviation industry.  Today we are joined by Frere Byrne of PlasmaLeap Tec...

Denmark made headlines in 2024 as the first country to implement a carbon tax on livestock emissions. The country's ambitious 70% emissions reduction target by 2030 includes agricultural reductions of 55-65%. What makes Denmark's policy truly remarkable isn't the tax itself—it's the 60% tax deduction corresponding to mitigation potential. This signals that Denmark's approa...

Animal Health as a Climate and Food Security Solution In this episode of the Ash Cloud podcast, we explore an often-overlooked opportunity in the fight against climate change with Dr. Nick Wheelhouse, Professor of Comparative Infectious Disease at Edinburgh Napier University and co-lead of the Global Research Alliance Animal Health and Greenhouse Gas Emissions Intensity Network. Dr. Wheelhouse bri...

The cost living is an increasing global challenge. Food inflation in 2023 was 13.6%, however food prices increased by up to 30% in many low income countries. Currently 60-80% of voters consider food price as a decisive factor in their choice of candidate and across 60% of countries food costs represent more than 25% of the CPI basket.  Right now, 670 million people—8.2% of our global population—ar...

"Sustainability means leaving the land in a better place, preparing the next generation for a turbulent future in agriculture... and it's probably also a license to produce." Robert MacKenzie and his farms on the mid north coast of NSW was the first Australian beef operation to become net zero through pasture carbon sequestration. Roberts journey began with a dedication to understan...

AgriFoodTech Venture Capital investment is down by roughly 90% from the high of 2021 with the lack of exits or creation of profitiable agtech companies resulting from the billions invested frequently taking the blame for investors looking for alternative places for put their money. But there are success stories.  Today we are joined by Mike Seely , the CEO of Native Microbials . Over the last 10 y...

There is a huge amount we can learn from Brazil’s transition from being a net food importer to one of the world’s largest food exporters over the last 50 years. Since deforestation across the Amazon peaked in the mid 1990’s Brazil has continued to invest in both driving productivity increases alongside increasing efforts to preserve wilderness areas and restore degraded lands. To help address clim...

Today we are joined by Jason Rowntree from Michigan State University where he is working on systems increase the resilience and to reduce the environmental harm of our food systems. Finding the driver across rural America that encourage farmers and ranchers to adopt management practices that improve soils, and protect local environments and the climate are a key priority of his work. Jason has bui...

The epigenome is essentially the control software for plants and animals that dictates when, where, and to what level different genes in the genome are expressed. Moderating the epigenome has the potential to upgrade crops in real time, during the season, to adjust photosynthesis and warn crops of upcoming droughts, diseases, or other threats. While traditional plant breeding and genetics requires...

Over human history animal protein has always been a luxury food. Meat is the first thing people generally chose to buy when they rise from lower to middle income.  With the current cost of living crises across the world, further food price inflation predicted due to climate change, geopolitical instability, and biodiversity loss, increasing impacts on productivity due to climate change, as well as...
