    Government policy to address today's food system challenges with Robert Bonnie former Undersecretary of Agriculture, USDA

    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 instability are all shifting more than they used to. Too often farmers and ranchers are left to carry that extra risk alone. Governments have a unique role to play here. "The question from a policy standpoint is how do you drive policy that is focused on the outcomes that folks want and that allow for the type of innovation you need in the private sector, and that de-risk the adoption of many of these practices, recognizing we actually don't have all the answers right now. We need to allow for innovation. How do we do that in a way that works for farmers while it also works for the public?" Robert Bonnie At the same time, new technologies and innovation are opening up ways to manage that risk that weren't available a decade ago. We already know that no-till, cover crops, crop rotation and better grazing make yields more stable through drought and flood. During the Biden administration, Robert tried to design crop insurance that would reward growers for adopting those practices because they reduce yield risk. "It's very hard to do. It's possible, I think, with new technology." That's now his focus at Sage, a startup using AI on soil data to support better insurance products and farm lending. He also draws a lesson from overseeing the US Forest Service in the Obama years. Every year firefighting took more of the budget, and less was left for the land management that stops catastrophic fires in the first place. Agriculture risks the same trap: paying for the disaster instead of the preparation. Robert served 12 years as a political appointee in the Obama and Biden administrations, most recently as USDA Under Secretary for Farm Production and Conservation. He is now a visiting scholar at UC Berkeley's Stone Center for Environmental Stewardship. Send us Fan Mail

    Is Solar-Geoengineering Too Risky? with Chris Parker

    In this Climate Chat episode, we interview interview climate scientist Chris Parker about climate change risks and have a discussion on the risks of doing solar-geoengineering (a.k.a, Sunlight Reflection Methods or Solar Radiation Management (SRM)) vs. the risks of not doing it. Chris Parker is a climate scientist and hydrologist specialising in translating global and UK climate projection data into practical risk assessments for government, regulators, and infrastructure providers. He was formerly Climate and Data Lead for the UK's Fourth Climate Change Risk Assessment – Independent Assessment (CCRA4-IA) at the UK Climate Change Committee, where he authored the national climate framing and led the Climate Chapter of the 'Well-Adapted UK' report. Over a 14-year career spanning engineering consultancy and the CCC, he specializes in bottom-up, adaptation-focused approaches to assessing climate risk at local and regional scale.

    Make Environmentalism Dangerous Again, with Nicholas Beuret

    **Warning: this episode contains swears** My guest on this episode of Your Brain on Climate says it's time environmentalism grew some teeth. He wants YOU to actively disrupt destructive activity – to sabotage the machines that are destroying the Earth – because asking politely isn't getting us where we need to be fast or fair enough. But yet hardly anyone is prepared to do stuff like this, despite rising temperatures and a planet on fire. So I ask: what does it take to get people taking disruptive direct action - and what stops the rest of us? Joining me is academic, author and activist Nicholas Beuret. Nic's the author of Or Something Worse: Why We Need to Disrupt The Climate Transition. Nic thinks modern environmentalism has got too polite, and accuses the environmental movement of not doing enough to force a transition that is making life better for everyday people. Nic is thoughtful, principled and funny - I think you'll like him - and just maybe you'll leave this chat reflecting on what it would take for you to chain yourself to a pipeline. Join me on the 4 October for Your Brain on Climate LIVE in Crystal Palace - tickets here. Let me know your thoughts on the show - hello@yourbrainonclimate.com. Please rate, review and subscribe, and share the show on socials. And do consider chucking this humble indie podcaster a few quid at www.patreon.com/yourbrainonclimate.

Your Brain on Climate is a show about human brains vs the climate crisis. It's hosted and produced by me, Dave Powell.
