The intersection between climate change and armed conflict is complex. For those who have not witnessed the difference between the devestation and social upheaval that results from war compared with any other form of social upheaval it is almost impossible to explain. This is why I see great importance in further understanding these intersections. Climate related violence is a messy marriage of climate stress and poor governance.ISIS profited from collapsing agricultural positions to bolster ...
Depending on who you speak with cattle can be vital to the sustainability of our food systems and our ability to provide health nutrition to humanity or they can be one of the largest sources of climate pollution. The culprit in this debate is methane, especially enteric methane emissions that is derived from the foregut of all ruminants including cattle. Frank Mitloehner is the Director of the UC Davis Clear Center that researches the intersection of animal agriculture and the environment an...
Regenerative ranching has recently gained traction across the main stream media but the idea of using livestock to mimic nature and managing a landscape holistically was largely led by Allan Savory from the 1980s. Rich Bradbury' parents attended the Savory Institute in the 1980's which was when he was first exposed to the holistic approach that Allan Savory brings to ranching. I recently caught up with Rich to hear how this has impacted his thinking and the way he manages his...
Nitrogen is absolutely essential for all forms of life, plants, animals and microbes. Nitrogen is the basis for making amino acids, and amino acids are the basis for making proteins, enzymes. The historic nitrogen system was balanced and based on microbial activity transforming atmospheric nitrogen into soluble forms usable by plants and microbes. Eric Davidson's has been working to transform our food systems through better understanding terrestrial nutrient cycling, cycling, greenhouse gas e...
The efficacy of methane reducing feed additives constantly varies between cows and herds because the rumen microbiome is constantly changing. Certain feed additives that worked really well at that one given her may stop working, or the other way around. Feed additives that were not working can become effective. Using AI based on the genome sequences within the microbiome so that the right additive is used at the right time can triple the impact of feed additives. Yaniv Altshuler has been work...
California has been leading efforts to implement climate change policy since Governor Schwarzeneger signed the Global Warming Solutions Act in 2006 to begin the transition to a carbon neutral economy with food and agriculture are a key component of California’s strategy. Agriculture sits right in the middle of the climate debate, agriculture is a significant emitter and that needs to be acknowleded. Agriculture also has the potential be big part of the solution and the conversation needs...
Rob Jackson is a climate scientist who has been leading global efforts to reduce millions of tons of greenhouse gas emissions and improve human health, safety, and air and water quality. Methane emissions are a major focus of Rob’s work as there is nothing else that gives as much power to slow global warming over the next decade or two. Rob’s new book, "Into The Clear Blue Sky” the path to restoring our atmosphere is being released at the end of July by Simon & Schuster. In th...
The Zero Net Emissions from Agriculture Cooperative Research Council (ZNE-Ag CRC) is a key component of achieving the commitment to achieve net zero emissions by 2040. The CRC comprises of 73 partenrs who have committed $AU87 million in cash which is matched by the Austrlain Federal Government. This becomes a $AU300 million program when in kind contributions are included. Richard Heath is the CEO of the ZNE-Ag CRC who brings decades of experience across research policy and hands on farming. I...
Maik Kindermann, the inventor of the methane inhibitor 3-NOP or Bovaer®. Earlier this week it was announced that Boaver has been approved for use by the FDA adding the United States to the other 59 countries where its available. Following a directive in 2008 from Feike Sifbesma, the former Chairman and CEO of dsm-firmenich Maik began working on a product to inhibit enteric methane. 16 years later Maik and his team have completed trials 119 and published 80 peer reviewed papers wit...
The security communities around the world including European, UK, US, and Australia have all recognized climate change as a National Security threat with climate change not being necessarily a direct cause of conflict but compounding the risks of conflict. The impact of climate change on food and water security is a key component of this increased threat. Neil Morisetti leads efforts to develop society's and policy makers understanding of the security implications of a changi...
There are currently 350 million people globally living with extreme hunger, with a plus 2°C rise in global temperatures this is forecast to rise to 539 million people, and with a plus 4°C temperature rise it is predicted that 2.1 billion people worldwide will be living with extreme hunger. Failing to adequately address this rise in extreme hunger will be a growing national security and global security issue as food insecurity is linked to increased migration and clonflict.

This episode of Ash Cloud is brought to you in partnership with CSIRO.Proteins play many critical roles in our bodies, and in the plants, animals, fungi and microbes that are our source of food and nutrition. Disease, brain function, appetite, movement, allergies, and thousands of other metabolic process all require proteins. This is in addition to the need for protein to build and maintain muscle. Growing global populations are dramatically increasing protein demand a...
Climate change is a global challenge, but interventions can only be implemented locally. Understanding the local cultures, economies, politics, language, and production systems is critical for any intervention to make an impact. Across the developing world the greatest opportunity to limit livestock methane emissions and improve food security is through improved animal nutrition and livestock genetics. In the developed world the opportunity lies in absolute methane emission reductions with ge...
Reducing methane emissions is the greatest opportunity to limit warming in the short term. With roughly 30% of current temperature increases are caused by methane, global food systems being responsible for 60% of methane emissions as a continuum from production to waste, and 80% of recent emissions have come from non-OECD countries the methane challenge intimately linked to the International development challenge.To address this solution that are fit for purpose need to be develop...
Recent farmer protests across Europe have highlighted the political battleground around sustainable agriculture. The absence of effective policies and support for a just transition to Net Zero is positioning farmers as political pawns who are being exploitation by people outside the farming community pushing their own agendas.Farmers are increasingly being squeezed between decreasing margins, increasing costs, increasing regulations, less market power. At the same time the growing polit...
The climate impact of animal agriculture is only one of the aspects that needs to be addressed for sustainable productions systems. The importance and urgency to mitigate methane emissions must be integrated with the social and economic aspects of livestock production and the other environmental issues such as nutrient management and biodiversity. The current state of our food systems are the result of decades and even centuries of the choices people have made which will take time to ch...
Growing anthropocentrism is one of the underlying root causes of our ecological crisis. In recent decades humans have become increasingly disconnected from our food. While for thousands of years obtaining food and water was the top priority of most human societies. Today, this is no longer the case and in today's society food is increasing becoming an a political issue, especially for meat and animal products. I recently caught up with Dr Sparsha Saha from Harvard University to discuss resear...
Less than 5% of climate finance is focused on addressing methane, and less than 2% of that finance is for the livestock sector. This is despite the fact that 155 countries agreed that rapidly reducing methane emissions from energy, agriculture, and waste is the single most effective strategy to keep the goal of limiting warming to 1.5˚C. The EPA estimates that 37% of methane emissions are from agriculture, with livestock contributing 32% of those emissions. Low and middle income c...
Of the 25 countries that are least able to adapt to the impacts of climate change about 14 of those countries or 56% are currently affected by armed conflict. The intersection of conflict and food insecurity is an area of series concern in many of the places where the International Committee of the Red Cross works. The 2023 global report of food crises reported that around 250 million people globally were food insecure and in need of urgent food assistance. This is the highest level in the se...
Currently over 50% of the world’s population is undernourished. There is generally not a shortage of food calories but a shortage of nutrients. This issue exists in rich countries, middle income countries, and poor countries. The traditional solution that has provided these nutrients to human populations for thousands of years is animals, both farmed livestock and hunted wild species.In recent decades the vast increase in the numbers of farmed livestock and how they are produced has created s...
