WRI Seminar – Dr Nina Welti, CSIRO

Apr 1, 12:00 pm - 1:00 pm

Speaker: Nina Welti, CSIRO Agriculture and Food

Title: Designing an integrated provenance system for agricultural products

Abstract: Food provenance has become a global priority for consumers, producers, and government authorities due to increasing food safety, environmental and authenticity concerns. Many nations are gross exporters of existing and emerging high value agricultural products that increasingly require robust, science-based integrated provenance systems to maintain and build their global position. In this talk, I’ll review the common analytical methods used to verify provenance and different provenance related priorities, practices and challenges using four commodities (beef, wine, grains, and seafood) as case-studies. The core requirements for a fully integrated framework will be outlined to deliver verified products along a traceable supply chain, based on three components. A purpose-fit analytical toolbox designed to verify the provenance of agricultural products. A repository platform for sharing spatial data in near real time is required to connect the crucial role consumer empowerment will have on generating data and closing the loop of this integrated framework. There are different approaches to developing an integrated provenance system are likely needed for commodities that are highly prized or susceptible to fraud compared to those in internationally competitive markets or seeking to increase profitability. In all cases though, an integrated provenance system will require a verifiable, coordinated, and technology-agnostic approach where government regulation, industry standards, and consumer expectations will equally be met.

Speaker Bio: Dr. Welti is a biogeochemist with a specialisation in isotope methods, to quantify sediment and soil-based biogeochemical processes. Of particular interest is developing tools which combine modelling and monitoring approaches in order to gain a better understanding of how anthropogenic changes impact key biogeochemical reactions.

Currently, Dr. Welti is developing methods to verify the provenance of agricultural products, linking traditional elemental and isotopic measurements with rapid scanning, remote sensing, and digital supply chains. She is part of the Impact Lead team for Agriculture and Food, focusing on Trusted Supply Chains.

Dr. Welti is the point of contact for the Waite Campus Indigenous Artist in Residence Program, which explores the nexus of western and indigenous knowledge using art to translate science.

The seminar will be both face-to-face in Charles Hawker Conference Centre and as a webinar.
