Real-world maths – A mathematical challenge to protect wildlife at scale
When a team of high‑school students in Perth sat down with a laptop and a stack of satellite images, they were not just doing maths – they were drafting a lifeline for one of Africa’s most iconic wildlife sanctuaries. The International Mathematical Modeling Challenge (IM2C) turned a classroom exercise into a race against poaching, habitat loss and climate stress in Etosha National Park.

What Happened
From 12‑16 July 2024, more than 150 student teams from 30 countries gathered online for the IM2C’s five‑day “real‑world maths” sprint. This year’s brief asked participants to devise a data‑driven protection plan for Etosha, a 22,000‑square‑kilometre reserve in Namibia that hosts over 200 species of mammals.
Australian schools led by Perth Modern School, Melbourne’s Mac.Robertson Girls’ High, and Queensland’s Brisbane State High entered the competition as a single regional coalition. Over 40 students collaborated across time zones, feeding their models with GPS collar data, ranger patrol logs and climate projections supplied by the Etosha Conservation Trust.
On the final day, each team presented a concise report and a set of actionable recommendations to a panel of mathematicians, ecologists and park officials. The Australian coalition earned a top‑three finish, with their “Dynamic Patrol Allocation” model singled out for immediate field testing.
Key Details
The winning model combined a Poisson‑process estimate of illegal activity with a Monte‑Carlo simulation of ranger movement. By optimizing patrol routes, the model predicted a 27 % reduction in poaching incidents over the next two years, translating to roughly 150 fewer animals harmed annually.
Data supplied by the park showed a 31 % rise in illegal snares between 2020 and 2023, and a 12 % decline in water‑hole usage during the dry season. The students’ model accounted for these trends by recommending mobile water stations at three high‑risk zones, a strategy that could boost water‑hole visitation by up to 18 %.
“We were stunned to see how a few equations could reshape real‑world decisions,” said Maya Patel, a Year 12 student from Perth Modern. “Our model isn’t just numbers on a page – it’s a blueprint that park managers can deploy tomorrow.”
Background
Etosha National Park, established in 1907, spans a semi‑arid savannah that supports iconic species such as the black‑rhino, African elephant and cheetah. In recent years, the park has grappled with increased human‑wildlife conflict, illegal hunting and the impacts of a shifting climate that has lengthened drought periods by an average of 2.3 months per decade.
The IM2C, launched in 2019, aims to bridge the gap between theoretical mathematics and pressing global challenges. Each year, the competition partners with a different conservation or engineering problem, providing students with authentic data sets and direct access to subject‑matter experts.
Why It Matters
Mathematical modelling offers a cost‑effective alternative to expensive field surveys, especially in remote regions where resources are scarce. By quantifying risk and optimizing limited ranger hours, the Australian team’s approach could save the park up to $1.2 million in enforcement costs over five years, according to a budget analysis from the Etosha Conservation Trust.
Beyond the immediate financial gains, the project underscores the growing role of youth‑led innovation in biodiversity protection. “When students bring fresh perspectives and rigorous analytics, we gain tools that are both scientifically sound and socially resonant,” noted Dr. Lindiwe Moyo, senior ecologist at the Trust.
What Happens Next
Etosha’s management has already scheduled a pilot of the Dynamic Patrol Allocation system for the 2025 dry season, integrating the model into their existing GIS platform. Rangers will receive training on the algorithm’s interface, and real‑time data from drone surveys will be fed back into the model to refine predictions.
Meanwhile, the IM2C organizers plan to expand the challenge’s scope, inviting interdisciplinary teams that include computer scientists, climate specialists and indigenous knowledge holders. A follow‑up symposium in November 2024 will showcase the Australian coalition’s findings alongside other top‑ranked submissions, fostering a global network of young problem‑solvers.
The collaboration between mathematics and conservation demonstrates that the next generation can wield equations as effectively as rifles, protecting wildlife not through force but through foresight.
