The urgency behind this call is grounded in a stark fact: soils contribute directly to at least 14 of the 17 SDGs. Nutrient cycling, carbon storage, water purification, and biodiversity conservation all depend on soil stewardship, making soil science central to SDGs 2 (Zero Hunger), 6 (Clean Water and Sanitation), 13 (Climate Action), and 15 (Life on Land). Yet the authors contend that prevailing paradigms of higher education remain inadequate, with many programs operating in disciplinary silos and clinging to what they describe as a soil pit perspective—insular, technically focused instruction that inhibits engagement with broader transdisciplinary contexts and reduces the visibility of soil science in addressing global sustainability objectives.

At the heart of the proposed reform is a matrix-based pedagogical framework that systematically maps key soil attributes—texture, cation exchange capacity, saturated hydraulic conductivity—onto ecosystem services and specific SDGs. For example, linking soil texture with water filtration and nutrient retention fosters an understanding of its relevance to SDGs 6 and 2. This approach enhances conceptual clarity while cultivating students’ ability to apply scientific principles to real-world environmental challenges. The framework draws on integrative concepts such as Soil Security, One Health, and the Pedometrics Challenge, positioning soil as a dynamic system embedded within socio-ecological landscapes rather than merely a physical and chemical entity.

The Omani case study offers perhaps the most comprehensive example of degree-level redesign. The Bachelor of Science in Soil Sciences at Sultan Qaboos University—the only undergraduate degree dedicated to agriculture and soil science in Oman—is a four-year, 126-credit program delivered in English and aligned with national accreditation standards. The curriculum emphasizes Oman’s unique arid and saline landscapes, including mountain terraces and traditional aflaj irrigation systems, providing regionally tailored yet globally relevant education. The program was scaffolded across three progressive phases of inquiry: Phase I, Direct Instruction, lays the scientific groundwork in topics such as environmental soil chemistry, soil physics, hydrology, and geographic information systems; Phase II, Structured Inquiry, engages students in guided projects examining salinity dynamics and soil microbiology; and Phase III, Open Inquiry, empowers students to lead multidisciplinary projects such as urban soil health assessments, hydropedological modeling of soilscapes, and land-use planning for water conservation.

A robust research-teaching nexus anchors the Omani program. Three key platforms integrate undergraduate learning with applied scientific inquiry: a Research Project Course offering structured opportunities for field-based investigations of soil and water systems; a competitive Undergraduate Student Research Fund Program providing grants and structured mentorship for independent and team-based research aligned with national development goals; and nationally competitive research grants funded by the Ministry of Higher Education, Research, and Innovation. Together, these platforms cultivate competencies in data interpretation, impact assessment, and science communication, advancing SDGs 4 and 17 while transforming the undergraduate experience into a trajectory of innovation and civic responsibility within Oman’s fragile but vital soil ecosystems.

Classroom-level innovations bring the framework to life. In the Soil and Water Conservation course, junior students engage in debate-based learning structured around formal guidelines and timing protocols. Each 25-minute debate session allocates 10 minutes for initial problem statements, a 12-minute rebuttal phase spanning three rounds, and 1-minute closing statements per team. Topics are deliberately controversial and regionally relevant—should groundwater in Oman remain private property or become a national resource, are more recharge dams a smart investment or an ecological misstep, is Oman ready to embrace treated wastewater as a source of drinking water. Empirical findings from a cohort of 51 students evaluating 17 reflective statements revealed high levels of positive engagement, with 96.1 percent agreement on improved teamwork and communication and over 90 percent agreement on the relevance of debate topics to the SDGs and Oman-specific issues.

The Soil and Water Winter Tour represents a flagship experiential course delivered as a five-day immersive field experience culminating in the Soil Skills Challenge, a structured team-based competition blending technical soil science tasks with real-world environmental problem solving. Field scenarios are deliberately complex and often wicked in nature—for instance, addressing secondary salinization in arid home gardens or installing precision irrigation systems—requiring students to synthesize competencies from hydrology, soil chemistry, landscape interpretation, and agroecology. The pedagogical architecture integrates problem-based learning, structured inter-team competitions, the data-information-knowledge-wisdom hierarchy, and constructive alignment theory. In post-course evaluations, over 95 percent of students confirmed that the challenge helped integrate knowledge across the curriculum and connect theory to practice in impactful ways.

The Russian case study at Moscow State University offers a complementary model rooted in a two-century soil science tradition. The undergraduate program spans 4 years of full-time study totaling 240 credits, organized into five core disciplinary domains: general social sciences, mathematics, chemistry, physics and geography, and agronomy and soil science. Students follow a uniform curriculum for the first two years before choosing a specialization in the third year, with 10 departments offering tailored courses in agroecology, soil biology, land resources, soil physics and erosion, and soil chemistry. Practical training includes nearly 4 months of summer fieldwork, supplemented with training in soil cartography, erosion control, and zonal soil surveys. The mandatory soil physics course combines 48 classroom hours of lectures with weekly laboratory sessions in which each student works with a unique soil sample collected from different layers of the same soil profile, allowing collective discussion of soil properties and functions in relation to the SDGs toward the end of the course.

The authors acknowledge significant hurdles in implementing these pedagogical strategies. Group-based activities sometimes led to uneven participation and varied individual learning gains, with insufficient ongoing evaluation and interpersonal frictions masking individual performance behind aggregate group results. Groups of 5 to 10 students proved sub-optimal, elevating the risk of social loafing. Field-intensive, research-based courses impose substantial time and logistical demands on both students and staff, and gaps in scaffolding between phases were evident in the Omani case. The authors recommend structured peer assessment, rotation systems for new faculty, recruitment of graduate teaching assistants, and clear public guidelines for publication and award attribution to ensure transparency and academic integrity.

Ultimately, the study calls for a global curricular reform positioning soil education as a cornerstone of sustainability science rather than a technical subdiscipline. Strategic recommendations include embedding SDG 4.7 into course outcomes and assessment frameworks, promoting interdisciplinary pedagogy linking soil science with environmental engineering, public health, economics, and policy studies, strengthening the research-teaching nexus through living laboratories and community-engaged science, and equipping students with modern tools such as HYDRUS modeling, GIS, remote sensing, and data analytics. The authors also advocate preparing students to function as policy advocates and knowledge brokers, establishing longitudinal impact assessment frameworks, and calling for greater visibility of soil in SDG policies and discourse. When soil is framed not merely as a scientific subject but as natural capital fundamental to planetary health, students emerge as sustainability stewards prepared to drive change across sectors.
