Abstract: Human–wildlife conflicts (HWCs) are on the increase due to shrinking space that results in increased competition for land, water, and other natural resources between humans and wildlife. Investigating the occurrence of HWCs is important in that the results can be used to formulate better management policies and strategies. In this paper, we describe the nature of HWCs emerging between humans and the Nile (Crocodylus niloticus) and between humans and the African (Hippopotamus amphibius; hippo) on Lake Kariba, Zimbabwe. Lake Kariba is the second largest manmade lake by volume in the world. Conflicts involving humans and these species are readily noticeable and played out around water bodies, which are sources of daily human sustenance and important habitats for aquatic wildlife. We used a mixed-methods approach to gather data on these conflicts, including questionnaires, face-to-face interviews, focus group discussions, and participant observation. The research participants involved national parks officials, fishing camp residents, and HWC victims. Our research confirmed that crocodiles and hippos have negatively affected humans through deaths, injuries, instilling fear, and destruction of sources of livelihood for fishermen such as fishing nets and boats. In retaliation, humans have implemented lethal methods to remove problem . The results of this research can inform the conservation community about the severity of the conflicts, which have been exacerbated by current economic hardships, to better inform conservation policies.

The animals involved in HWCs differ from saltwater crocodiles (C. porosus; Fukuda and the impacts to humans may not be evenly et al. 2014, Amarasinghe et al. 2015, van der Crocodile and hippo conflicts in Zimbabwe • Marowa et al. 213

This affects the manner in which hippos utilize resources and survive in areas with a high density of human popula- tion and continuous land use changes (Kanga et al. 2011). The differences in the use of space of the 2 animals shape the ways in which they come into conflict with people.

Study area We conducted research between December 2018 and August 2019 in the fishing camps lying along Lake Kariba. Lake Kariba is located approximately 365 km northwest of Zimbabwe’s capital city, Harare (Muringai et al. 2019). We studied the fishing camps of Nyaodza, Gache- Gache, and Fothergill, located in the immediate Figure 2. An African hippopotamus (Hippopotamus vicinity of the Kariba town.
