The Carbon Storage Partnership (CSP) is a multi-party transdisciplinary consortium developing
knowledge and technologies required to underpin profitable, sustainable and socially acceptable
pathways to a carbon-neutral livestock sector by 2030.
A literature review to determine how grazing management impacts soil carbon, biodiversity,
livestock production, profitability and ecosystem services in Australian grazing systems is in the final
stages of completion. We are continuing the expansion of this literature review by including
additional articles that determine qualitative factors, such as farmer cues for making decisions.
Results suggest that across sites and production systems, grazing management (1) has no significant
impact on soil carbon or long-term ground cover, and (2) may positively impact pasture production
when conducted at low intensities. When completed, outcomes of the review will be used to
develop recommendations of regionally specific grazing management approaches to achieve
beneficial and synergistic environmental and production outcomes and will partially inform the
mitigation pathways to be modelled in the next 12 months.
Nineteen semi-structured interviews have been completed, with a further five to be undertaken
across the four NSW agroecological zones, namely, Southern Tablelands, Central Tablelands,
Northern Tablelands and Western NSW. While these interviews are behind schedule, they are being
done in a more thorough way so that the data collected is suitable for scientific publication.
Preliminary findings from the interviews will be presented in the next Milestone Report. The soil
carbon data from the long-term experiments has been analysed and a publication is being prepared.
The CSP Communications and Extension plan has been reviewed and updated, and a listing of all
activities has been provided, with engagements totalling around 1.7 million to date. In addition, a
range of specific activity outcomes have been included here, such as an industry webinar on
management strategies for improving soil carbon, found via this link: International Fertiliser Society,
a draft fact sheet and an abstract for the NRM Knowledge Conference to be held next month in
Western Australia. Development of a Carbon Storage Partnership website is progressing, with draft
content contained in the appendices.
The 10 case study farms for biophysical, economic, greenhouse gas emissions, natural capital and
biodiversity have been selected. Data collection sheets have been forwarded to each case study and
collection of this data will commence as soon as Human Ethics approval, through UTAS, has been
received. A protocol for biodiversity and natural capital analyses, along with a draft protocol for the
economic assessment of biodiversity and natural capital have been completed. The draft protocol
for economic assessment will be reviewed and updated as required to meet project deliverables.
