Through our Soil Health Series, we’ve been exploring all the ways soil is crucial to sustainable cotton production. From increasing productivity and yields to capturing carbon, soil is the foundation of farming and a vital part of our work at Better Cotton.
With our 2030 Strategy and revision of the Better Cotton Principles and Criteria (P&Cs), we have been going further to prioritise soil health in our programme. Soil health is one of five impact areas identified in our Strategy, and we have been working hard to develop the associated soil health targets and indicators. In addition, we are working to introduce new requirements that will strengthen our approach to soil health in our P&Cs.
Soil Health Indicator and Target Setting
Each of the five impact areas in our 2030 Strategy will have a target accompanied by one or more indicators to monitor and measure progress made on farms. These will help us focus our work and build momentum for change at scale.
To help us define the concept of soil health, identify relevant indicators, and ensure our approach is scientifically sound and credible, over the last few months we have been working with the consultancy SalvaTerra. SalvaTerra began by looking at the FAO definition of soil health, which emphasises four key aspects at the heart of soil dynamics: mineral composition, organic matter content (SOM), biodiversity and associated biological activity.
From the definition and other research, SalvaTerra identified Soil Organic Carbon (SOC) – the more readily measurable portion of SOM – as a useful way to assess overall soil health. Among other things, high levels of SOC promote biodiversity and fertility and filter water to support healthy, thriving crops. There is also a significant link with climate change mitigation, as soils are an important store of carbon in a world facing a climate crisis. As a result, there is an opportunity to link SOC with payments for ecosystem services. We recognise that we need to be very cautious about this approach and the validity of associated claims, however.
We are now assessing the suitability of different approaches which could allow us to monitor changes in SOC at scale across the countries we work in. The options include direct soil sampling and monitoring the adoption of sustainable soil management practices, which are evidenced to increase SOC. Each approach has its strengths and weaknesses, and we are currently exploring these further. Alongside talking to soil scientists, experts, farmers and partners, we are also gathering baseline data in several Better Cotton programme countries.
Using this information, we plan to publish our soil health target and indicator towards the end of 2022.
Revision of Soil Health in the Better Cotton Principles and Criteria
Another way we’re working to strengthen our approach to soil health is through our revision of the Better Cotton Principles and Criteria (P&Cs), which sets out the global requirements that all producers must meet in order to be licensed to sell Better Cotton. With the revision, we aim to align the P&Cs with Better Cotton’s 2030 Strategy and aim to ensure that the licensing requirements remain relevant and effective to bring sustainable change at field level. As such, this is a key driver for Better Cotton to reach its ambitious 2030 Strategy and related aims and targets.
While the requirements will be kept broad enough to apply on a global level, they will be accompanied by local implementation guidance to address the significant differences between the different cotton growing regions – allowing all Better Cotton Farmers to embark on this journey towards improved soil health, no matter what their starting point is.
The revision of the P&Cs will continue into 2023 and we will be starting a two-month public consultation period on Thursday 28 July. Find out more and take part.
