    In this paper, we propose an ISTVS Wheel/Track Design Student Competition to engage students in terramechanics through hands-on experience in off-road mobility design and testing. The competition will challenge student teams to design and fabricate a wheel or track system for a small unmanned ground vehicle (UGV), evaluated through tractive performance and mobility tests on selected soil types. By emphasizing low-cost, practical methods, the initiative ensures accessibility for students from diverse backgrounds. Teams can use free CAD software, 3D printing, or other rapid prototyping techniques to minimize expenses. The competition will feature two main components: a laboratory-style single-wheel test rig to assess tractive performance, and a small UGV platform for field-based mobility tests. Performance metrics may include drawbar pull, sinkage, slip, traction, and slope climbing, following ISTVS standards (He et al., 2020). Each competition will include design presentations and structured scoring criteria evaluating both design quality and performance. A standardized test matrix will assess structural integrity and functional performance. This initiative provides experiential learning opportunities, encourages innovation, and strengthens student engagement with ISTVS—cultivating the next generation of terramechanics engineers.

    Climate change inflicts substantial economic damage on developing African nations, threatening progress towards the UN Sustainable Development Goals. There are synergies between actions needed to tackle climate change and other ongoing development priorities for Africa, including infectious disease control, facilitating clean energy access, reducing air pollution, tackling malnutrition and food insecurity, and providing universal health coverage. Action to protect human health against climate change needs to be integrated into all systems that are responsible for delivering essential services and implementing policies across all sectors that underpin the attainment of key development priorities for Africa. These systems include the Sustainable Development Goals and the African Union's 2063 Agenda for building The Africa We Want, and the ongoing negotiations and work programmes in the UN Framework Convention on Climate Change. Adequate stocktaking of and access to robust data and scientific evidence is needed to support this effort and guide priorities for policies that protect and promote health and for monitoring progress over time. In response to this need, the Lancet Countdown is launching a new initiative to bring together a transdisciplinary research collaboration to help build regional capacity, strengthen existing networks, generate evidence, and mobilise data across numerous domains at the climate change and health nexus in Africa.
