The Kavango-Zambezi Transfrontier Conservation Area (KAZA TFCA) spans five countries: Angola, Botswana, Namibia, Zambia, and Zimbabwe. ​ It is the world’s largest transfrontier conservation area, hosting the largest contiguous population of African elephants, a quarter of the African wild dog population, and 20% of the lion population. ​ The region is home to approximately 3 million people, primarily rural communities reliant on subsistence farming. ​ Human-Aquatic Animal Conflict (HAAC), particularly involving crocodiles and hippopotamuses, has become a significant issue due to increasing human populations and expanding settlements near water bodies. ​ Crocodiles are opportunistic predators, attacking humans and livestock, especially in areas with depleted fish stocks. ​ Hippos, known for their aggressive behavior, are responsible for crop damage, destruction of fishing gear, and human fatalities, often near water bodies or grazing paths. ​
The manual aims to improve understanding of HAAC and equip stakeholders with best practices to mitigate conflicts. ​ Recommended measures include constructing crocodile-proof barriers, providing alternative water sources, mapping HAAC hotspots, and relocating problem animals. ​ For hippos, strategies include fencing lands, creating buffer zones, digging trenches, and educating communities about hippo behavior. ​
Training programs for farmers, wildlife managers, and stakeholders are essential to enhance technical capacity and awareness. ​ Effective mitigation requires accurate data on conflict hotspots, robust support programs, and active participation from all stakeholders. ​ Adequate resources, innovative approaches, and continuous implementation of interventions are critical for success. ​
KAZA TFCA’s mission is to sustainably manage the region’s ecosystem, heritage, and cultural resources through conservation and tourism, benefiting local communities and stakeholders. ​ The manual provides practical solutions to foster coexistence between humans and aquatic animals, ensuring ecological balance and supporting the tourism industry. ​ For inquiries, contact the KAZA TFCA Secretariat or partner state departments. ​
