Submit your Research - Make it Global NewsSouth Africa's unparalleled biodiversity faces a rapidly evolving landscape of threats and opportunities, as outlined in a groundbreaking 2026 horizon scan published in the journal AMBIO. Led by researchers from the South African National Biodiversity Institute (SANBI) and several leading universities, this study pinpoints ten emerging issues poised to shape conservation efforts over the next five to ten years. With South Africa boasting nearly 10% of the world's vascular plant species and six major biodiversity hotspots, proactive strategies are essential to safeguard these irreplaceable natural assets.
The scan, a follow-up to the 2020 edition, employs a rigorous Delphi method involving 14 experts from academia, government, NGOs, and private sectors. Participants submitted 51 potential issues, refined through scoring and discussion rounds to select the top ten. These challenges underscore a shift from traditional threats like habitat loss to more nuanced pressures involving technology, energy transitions, and regulatory hurdles. Most issues fall into the 'complex' category, demanding not just scientific solutions but also social, economic, and political collaboration.
Understanding Horizon Scanning in Conservation
Horizon scanning is a forward-looking tool used globally to anticipate emerging risks and innovations. In biodiversity contexts, it helps conservationists move from reactive firefighting to strategic planning. The process begins with experts scanning literature, media, and networks for nascent trends. Issues are then anonymously scored on novelty, plausibility, and severity, followed by facilitated discussions to resolve debates.
For South Africa, this approach is particularly vital given the country's unique position. Home to over 20,000 plant species—more than half endemic—and iconic wildlife like the Big Five, the nation grapples with intensifying pressures from climate change, land-use conversion, and invasive species. Previous scans, including a global 2026 edition identifying 15 issues, highlight parallels like AI disruptions, but the local focus reveals context-specific vulnerabilities such as water scarcity and mining legacies.
Energy Transitions and Infrastructure Pressures
South Africa's push toward a just energy transition amplifies demands for critical minerals like lithium and cobalt, alongside green hydrogen projects. These initiatives risk fragmenting arid ecosystems, particularly in the Northern Cape. For instance, lithium mining expansions could disrupt habitats for endangered species like the Riverine Rabbit, already critically threatened by habitat loss.
Compounding this, the proliferation of utility poles for renewable energy transmission and telecommunications creates 'landscape pollution.' Studies show these structures provide nesting sites for invasive pied crows, which prey on small mammals and birds. In the Karoo, where open landscapes support unique reptiles and plants, such infrastructure could exacerbate fragmentation.
Non-aqueous fracking, using foam-based proppants to minimize water use, reemerges as a concern in the shale-rich Karoo Basin. While addressing water scarcity, it still poses risks of groundwater contamination and seismic activity, threatening fragile endemics. Historical debates over hydraulic fracking moratoriums underscore the tension between energy security and conservation.
Technological Double-Edged Swords: AI in Conservation
Artificial intelligence promises transformative tools for monitoring, such as camera traps and apps like iNaturalist. Tiny machine learning models enable edge computing on low-power devices, ideal for remote African savannas. Yet pitfalls abound: biased training data underrepresents rare species, leading to misidentifications.
More alarmingly, 'user-friendly but expert-free' AI tools risk hallucinations—fabricated outputs—in critical applications like environmental impact assessments. Rates as high as 91% in some models could mislead policymakers, amplifying errors in permitting processes. South African experts call for mandatory AI disclosure and validation protocols.

Agricultural and Pesticide Crises
Croplands cover over 15% of South Africa's land, driving pesticide overuse amid outdated 1947 legislation. Resistance in malaria vectors like Anopheles mosquitoes exemplifies cascading effects: non-target species decline, soil microbiomes suffer, and agricultural intensification loops back to biodiversity loss.
Climate change, trade tariffs, and biosecurity heighten these pressures. Calendar-based spraying ignores pest cycles, while EU bans on 62 insecticides unavailable in SA flood markets. The scan urges regulatory overhaul to prevent 'superpests' and protect pollinators essential for 75% of crops.
The Green Water Cycle and Vegetation Loss
Natural vegetation generates about 50% of South Africa's precipitation via transpiration—the 'green water cycle.' Converting it for agriculture or plantations disrupts this, with 20% of evaporation originating from neighboring countries. In water-stressed regions like the Western Cape, this exacerbates droughts, as seen in recent fynbos die-offs.
Integrating green water protection into spatial planning is critical. Case studies from the Succulent Karoo show vegetation clearance halves local rainfall contributions, threatening endemic plants comprising 40% of species.
Regulatory and Knowledge Barriers
Overlapping regulations lock vital biodiversity data, stalling research for national assessments. Permit delays hinder invasive species tracking, vital as aliens cost SA R14 billion annually.
Biodiversity litigation rises, leveraging constitutional rights. Over 230 global climate cases in 2023 inspire SA efforts, but accessibility challenges communities. Universities like UCT's Biodiversity Law Centre advocate streamlined processes.
South African Universities at the Forefront
This scan exemplifies collaborative research across SA institutions. Stellenbosch University's Centre for Sustainability Transitions contributed on energy issues, while University of Johannesburg's zoologists addressed AI pitfalls. Wits and UCT experts highlighted infrastructure and litigation.
Such interdisciplinary work positions SA higher education as a biodiversity hub. Programs like UJ's MSc in Biodiversity & Conservation train future leaders, integrating horizon insights into curricula. SANBI partnerships foster knowledge exchange, vital for Global South contexts.

Implications and Pathways Forward
The scan classifies nine issues as 'complex,' urging adaptive governance. Recommendations include pesticide law updates, AI ethics frameworks, and cross-sector forums blending hydrologists with planners.
Success stories like the Working for Water programme, clearing invasives while creating jobs, offer models. Future scans every five years, expanding stakeholders, will track progress amid CBD commitments.
For students and researchers, opportunities abound in AI validation, green infrastructure design, and litigation support. Engaging now ensures South Africa's biodiversity legacy endures.
Global Context and SA's Unique Position
Aligning with the global 2026 scan's AI and food demand warnings, SA's emphasizes local realities like Karoo fracking. As a megadiverse nation contributing to Kunming-Montreal Framework, proactive steps position SA leadership in African conservation.
Stats paint urgency: 79 plant extinctions confirmed, estuaries 99% threatened. Yet, with university-led innovation, reversal is possible.
