The Nexus Solution to Global Existential Challenges (Soil Security Series)

Save Soil (on behalf of Isha Outreach, IUCN Member) and Aroura, the Soil Security Think Tank, are excited to co-host a 3-part panel discussion on Soil Security. As part of the larger Save Soil Soil Conversations series, this collaboration will explore soil as the single leverage point for addressing major global challenges of our time, highlighting rich, diverse stories of challenges and successes from around the world. Expert panelists will share their insights and on-ground experiences on how Soil Security can support accelerated implementation of restoration targets, biodiversity goals, and climate action.

 Soil Security is essential to sustaining biodiversity, restoring ecosystems, and enabling climate resilience. Yet, soil remains largely invisible in conservation policy and practice. As land degradation accelerates, its effects ripple throughout the biosphere, accentuating the urgent need to bring soil restoration into global conservation frameworks.

The Soil Security, a concept and framework developed by Professor Alex McBratney and colleagues from the University of Sydney, offers a holistic, local approach to soil assessment, stewardship and policy through five interconnected dimensions: Capacity ("What can this soil do?"), Condition ("How is this soil now?" often associated with Soil Health), Capital ("What is this soil worth?"), Connectivity ("Who cares and knows about this soil?"), and Codification ("What are the rules governing this soil?"). Albeit local, this framework enables science-based monitoring, governance, and restoration of soils, offering a grounded pathway to securing soil as a living entity and all the life that it supports at the regional, national, and international levels. 

Panel 1 - Soil Security: The Nexus Solution to Global Existential Challenges 

Abstract: 

Panel 1 of this series will explore the Soil Security Framework and the soil nexus approach within it, answering the question of why soil is at the heart of nature conservation for One Health. Expert panelists will present on measuring the Capacity and Condition dimensions of the Soil Security Framework, through their work in Kenya, Indonesia, and Australia, three regions of the world with rich biodiversity facing high rates of soil and land degradation and ecosystems vulnerable to climate shocks. We will see how their work has brought about restoration and resilience at the landscape, social, and the ecosystemic level and the gaps that still need to be addressed and what we all can do to address them.

Moderator:

Dr. Julio C. Pachón-Maldonado 

Postdoctoral Research Associate in Soil Security: Codification-Connectivity/Pedometrics, Sydney Institute of Agriculture & School of Life and Environmental Sciences, 

The University of Sydney

Julio Pachón is a soil scientist whose work centres on soil security, particularly the dimensions of Connectivity—people’s awareness and engagement with soils—and Codification—the legal and policy frameworks that protect them. He has collaborated with stakeholders across Europe, Africa, South America, North America, and Australia, combining field-based pedological experience with advances in digital soil mapping and policy analysis. His current focus is on self-assessment tools that allow farmers, policymakers, and land managers to connect directly with the latest soil research in a personalised way, while also exploring how artificial intelligence can assess legislation and strengthen governance frameworks that bring soils into global sustainability debates.

Dr. Wartini Ng

Postdoctoral Research Fellow in Soil Security & Soil Carbon

Sydney Institute of Agriculture & School of Life and Environmental Sciences

The University of Sydney

Wartini Ng is a Postdoctoral Research Fellow whose work advances soil security, with a focus on evaluating soil capacity and condition to safeguard soil into the future. Her research integrates advanced data analytics, proximal sensing, and machine learning techniques to improve the prediction of soil properties using large spectral databases. She now applies these approaches with digital soil mapping, strengthening the assessment of soil capacity and condition as a foundation for long-term soil security.
