The 23rd World Congress of Soil Science commenced in Nanjing, Jiangsu Province, marking a historic milestone as the first time this prestigious global gathering has ever been hosted in China. Often described as the “Olympics” of the soil science community, the event unfolded from June 8 to 12 under the overarching theme of “Soil and the Shared Future of Humankind.” This congress is recognized worldwide as an eminent academic forum, drawing soil scientists, policymakers, and industry experts from every corner of the globe to address critical issues facing our planet through the lens of soil science.
Hosted by the Institute of Soil Science at the Chinese Academy of Sciences and co-organized by the International Union of Soil Sciences alongside the Soil Science Society of China, this congress convened nearly 3,000 attendees hailing from over 100 countries. The assembled experts represent a broad spectrum of disciplines within soil science, uniting around pressing global challenges such as soil health degradation, food security imperatives, biodiversity loss, climate change impacts, and the quest for sustainable development practices. This international collaboration reinforces soil’s central role as a fundamental component of life on Earth.
At the inauguration ceremony, leading national and regional scientific authorities underscored soil’s pivotal function as the bedrock of terrestrial ecosystems and agricultural productivity. Soil was portrayed not only as a finite and indispensable natural resource but also as a dynamic matrix integral to ecological balance and human survival. Speakers emphasized that fostering deeper global scientific cooperation and knowledge exchange in soil science is paramount to protect ecosystems, drive sustainable agricultural practices, and effectively respond to accelerating environmental changes triggered by human activities and climate variability.
The congress’ intensive five-day agenda offered an unparalleled platform for intensive academic exchange. Participants had access to 9 symposia and 5 focused workshops, as well as more than 100 simultaneous sessions where over 2,800 presentations—comprising 2,000 oral and 800 poster contributions—illuminated recent advancements and novel methodologies in soil science research. The breadth of topics ranged from soil biogeochemistry and microbial ecology to the application of remote sensing technologies and artificial intelligence in precision soil mapping and management.
A notable highlight was the exhibition of the NEW Community, an interdisciplinary academic network centered on flagship journals such as Biochar and Carbon Research. This community amalgamates a diverse portfolio of scientific publications covering fields like agricultural ecology, environmental AI applications, biochar technology, biocontaminants, sustainable carbon material development, nitrogen cycle dynamics, energy systems, and emerging contaminants. The NEW Community’s presence at the congress shed light on the interconnectedness of soil science with broader environmental and technological domains.
NEW Community’s underlying ethos—anchored in sharing, collaboration, and innovation—was manifest in its support for numerous academic initiatives including thematic seminars, international meetings, and community-building efforts that foster cross-disciplinary interactions. The substantial interest generated by its exhibition booth reflected scientists’ enthusiasm for leveraging integrated research approaches to propel soil science forward, especially in relation to advancing carbon neutrality strategies and enhancing environmental health outcomes.
Adding prestige to the congress, five luminary scientists were formally named Honorary Members of the International Union of Soil Sciences during the opening ceremony. These honorees were recognized for their sustained and transformative contributions to soil science understanding and the advancement of sustainable agricultural practices worldwide, reinforcing the Congress’s commitment to honoring excellence and inspiring future generations of soil researchers.
Beyond scientific discussions, the congress also served as a vital platform to elevate China’s strategic role within the global soil science community. Hosting the event symbolically and practically deepens China’s involvement in shaping future research agendas and international cooperation frameworks dedicated to the sustainable stewardship of soil resources. This aligns with China’s increasing leadership in environmental sciences, agricultural innovation, and climate initiatives on the world stage.
Outcomes of this seminal gathering are set to feed directly into the Nanjing Action Initiative, a strategic roadmap intended to guide international soil science research and collaboration over the forthcoming decade. The Initiative aims to galvanize cross-border partnerships, harmonize research priorities, and promote policy translation to address emerging challenges related to soil degradation, ecosystem restoration, and resilient agricultural systems in a warming and increasingly urbanized world.
The comprehensive programming and rich dialogues underscored the multifaceted nature of soil science, encompassing fundamental soil physics, chemistry, and biology, as well as applied research targeting real-world environmental and food system challenges. Innovations presented included breakthroughs in soil carbon sequestration techniques, novel biochar applications for soil remediation, digital agriculture tools integrating AI and machine learning, and new modeling frameworks to better predict soil-plant-climate interactions.
Underpinning all discussions was a shared acknowledgment that soil science stands at the crossroads of multiple scientific frontiers—intersecting with climate science, ecology, environmental engineering, and socio-economic policy—necessitating an integrative and collaborative approach for long-term sustainability. The congress exemplified how harnessing such interdisciplinarity can unlock transformative solutions to global challenges ranging from land degradation neutrality to meeting increasing nutrient demands.
In summary, the 23rd World Congress of Soil Science in Nanjing not only celebrated a milestone in soil science history but also charted an ambitious new trajectory for the discipline, emphasizing international collaboration, technological innovation, and the critical role of soil in sustaining life on Earth. Through seminars, exhibitions, and high-level dialogue, the congress reinforced the urgency and opportunities within soil science to support resilient ecosystems and secure a sustainable future for all humankind.
