Tropical grasslands, such as the savannas of Africa, are among the most biologically and economically significant ecosystems on Earth. These landscapes support diverse flora and fauna, provide grazing lands for livestock, and contribute to critical ecosystem services such as carbon storage, soil fertility, and water regulation. However, their ecological and socio-economic value is under increasing threat from invasive species. The introduction and spread of invasive plant and animal species in tropical grasslands have disrupted native biodiversity (Mpondo et al, 2024), altered ecosystem processes, and strained livelihoods dependent on these ecosystems (Ulimboka et al, 2024). These species often out-compete native vegetation and animals, degrade habitat quality, and exacerbate the risks of wildfires and desertification. Their impacts are further intensified by climate change, land-use transformations, and inadequate management strategies.

This symposium will explore the current researches on invasive species in Africa tropical grassland. Topics will include the pathways of invasion, the drivers facilitating their spread, and the impacts on biodiversity, agricultural productivity, ecosystem health, and community livelihoods.

Equally, the symposium will highlight emerging and proven management strategies, including early detection and rapid response systems, biological control measures, community-led initiatives, and policy frameworks. By integrating scientific research with on-the-ground practices, we aim to identify actionable solutions for mitigating the impacts of invasive species while promoting the resilience and sustainability of tropical grasslands in Africa.

This forum provides a platform for scientists, conservationists, policymakers, and stakeholders to collaborate on preserving the integrity of Africa’s tropical grasslands in the face of this growing challenge.
