Matthew Harrison. It’s widely promoted for its environmental benefits. But how does it actually affect farm profitability and greenhouse gas emissions? Evidence remains limited. One reason is that regenerative agriculture is usually presented as a bundle of practices...

Without agriculture, hundreds of millions of people would go hungry every day. Yet modern agriculture is increasingly judged not just on how much food it produces — but on how well it stores carbon, protects biodiversity, and reduces emissions. Farmers are being asked to deliver food, climate solutions and conservation outcomes, while still running profitable businesses.

Professor Matthew Harrison. While practices for reducing or removing greenhouse gas (GHG) emissions abound, little information exists on the combination of practices required to reach net-zero emissions, the cost of transitioning to net-zero, or how carbon removals may change under hotter and more variable conditions expected with climate change. ARR.News asked a few further questions of Professor Harrison.

Matthew Harrison, uTas. A webinar was held  relating to how planting trees on farm impacts on biodiversity and natural capital. A range of models were used to examine spatially-explicit carbon sequestration and changes in biodiversity over time.

How does planting native tree species impact on farm-level biodiversity? With funding from MLA, AWI and several other partners, the "Sustainable Pathways to CN30" project team are examining this question via co-development of farm systems interventions for reducing greenhouse gas emissions while improving productivity, profitability and biodiversity.

Matthew Harrison. With global temperature rise likely to exceed 1.5oC by 2050, interest in the development of skills, practices and technologies for removing carbon dioxide to avoid dangerous climate change abounds. One way to do this is via improved storage of soil organic carbon (SOC), as incremental gains in soil carbon at scale can have massive effect on residual CO2 circulating in the atmosphere.

Scott Duxbury from YF.TV discusses the challenges and opportunities in achieving sustainable food production and reducing greenhouse gas emissions with Matthew Harrison, lead author of the research report 'Clarifying confusions over carbon conclusions' from the University of Tasmania. The discussion explores strategies such as soil carbon sequestration, regenerative agriculture, and reducing food waste that can help us move towards a more sustainable and equitable food system.

Assoc. Professor Matthew Harrison presents the results of a comprehensive study on the costs of transitioning farming systems across Australia to net zero emissions using a range of practical models. The study found that there are multiple pathways to net zero.

Prof Mitloehner's presentation covers a range of issues relating to methane and carbon dioxide in terms of global warming, climate neutrality, GWP100, GWP*, implications for the livestock sector and action to reduce global methane emissions.

Matthew Harrison's presentation covers a range of issues relating to soil carbon markets, from changes in soil carbon over time to whether we should rethink soil carbon markets, beginning with the key question: why all the hype about soil carbon?
