Optimal Carrying Capacity - In Conversation With Robert Barbour
We are joined by the Sustainable Food Trust's Senior Researcher Robert Barbour for our sixth episode of this season. Tune in to discussions surrounding methane, carbon footprints, and the complexities and challenges of measuring environmental impacts associated with livestock. Robert draws on his experiences as a researcher and his family farm (an upland beef and sheep farm that also produces timber in Highland Perthshire, just north of Pitlochry), to dive into the positive role livestock can play from a food systems and environmental perspective. He considers grazing strategies, livestock breeds, and the role herbal leys can play, whilst emphasising the productivity levels that can be achieved in pasture-based systems. He points out his family farm is running a system that has very low levels of inputs so what determines their carrying capacity is largely what the land can naturally support, and one limiting factor for them is a lack of early season grass growth. Show notes: Explore the two papers by Hannah Van Zanten, the paper Robert wrote with Richard Young and Michael Wilkinson that looks at the production of meat and milk from grass, the Agricology profile of his family farm, and learn more about GWP and GWP* here: https://tinyurl.com/5dr8kv75

Optimal Carrying Capacity - In Conversation With Simon Fairlie
The fifth episode of the season finds us in conversation with Simon Fairlie, recorded earlier this summer when he was still running his dairy operation at Monkton Wyld Court in Dorset. Simon, who was once described by the Guardian as “the most influential and unusual eco-activist you might not have heard of”, brings us a wide ranging conversation that looks at the micro and the macro of carrying capacity. You’ll find us discussing how he managed his herd of two as he produced a range of dairy products for the ‘intentional community’ at Monkton, and how he dealt with grazing and hay production whilst improving grasslands and considering the ecological benefits his approach brought to the 8 acres under his management. This couples with a wider food systems discussion around the role of livestock, rewilding, methane emissions, and the issues associated with an unbalanced production system where he argues the case for a return to mixed farming being required.

Optimal Carrying Capacity - In Conversation With Bill Grayson
In this fourth episode we are joined by renowned conservation grazier Bill Grayson who brings us his perspective on the concept of optimal carrying capacity and the way that it is deployed within the system he and his wife Cath run as part of the Morecambe Bay Conservation Grazing Company. He discusses how they go about planning putting animals on to a piece of land, the various practical considerations, and the role livestock play and the benefits they can bring to the land, along with the main challenges in relation to the conservation grazing picture against a backdrop of a pervading opinion of ruminants causing climate change. We touch on the impacts of stocking rate, forage management, breed selection, extended calving period, the set stocking versus mob grazing approach, and the difference between ‘maximum sustainable output’ (essentially an economic interpretation) and optimal carrying capacity, and how it fits with agroecological principles.

Optimal Carrying Capacity - In Conversation With Kate Still
This third episode of the new Agricology podcast season features Kate Still from the Soil Association’s Farming and Land Use team. Kate comes to the conversation with a whole farm approach in mind and the need to balance what farms can support to create healthy animals, healthy farmers and a healthy farm bank balance with as few inputs as possible. Her quiet wisdom comes across as she considers strategies and approaches to optimising rather than maximising livestock production. We discuss the highlights from some of the Innovative Farmers field labs Kate’s been involved with, which have looked into strategies including the use of herbal leys, winter forage options and transitioning to new grazing systems. We speak about the challenges of getting new grazing strategies ‘right,’ having the infrastructure to make rotational grazing happen, and training staff to be able to do this. Show notes: Read about the field labs Kate mentions, the University of Reading diverse forage programme, and the work of New Zealand Advisor John King here: https://tinyurl.com/5dr8kv75

Optimal Carrying Capacity - In Conversation With Dr Lindsay Whistance
In this episode we are joined by Dr Lindsay Whistance, Senior Livestock Researcher at the Organic Research Centre. Lindsay, who started her working life as a dairy herds-woman, comes to the conversation through the lens of animal welfare. The episode is an enlightening exploration of thoughts and ideas relating to optimal carrying capacity. It covers topics including the important partnership between humans and livestock which can be lost when animals are reduced to being just a tool, and the need for wider acknowledgement of animals' fundamental place in the ecology of a landscape, being critically important to ecological health. Lindsay touches on how we can provide for animal’s needs, farming in a way that allows animals to adopt natural behaviours, and approaches that can help balance the relationship between human, animal and environment. She also considers peoples different conceptions of "good animal welfare" and the challenges associated with focusing on health in the round.

www.agricology.co.uk is a hub that explores moving towards farming systems that harness ecological processes & holistic approaches to help balance productive agriculture with enhancing the wider environment. In 2020, we chatted with some of the movers & shakers in the fields, labs & food supply chains; focusing on sustainable farming practices in ‘Agroecology in focus’ & speaking with innovating farmers ‘In the field.’ We are back in 2024 ‘In conversation with’ an exciting line up of farmers, researchers, advisors & industry figures who we set out to explore the practical, philosophical & pertinent with in relation to balancing the health of the farm with the environment & farming in a way that aims at ensuring a resilient future for us all.
