Photographer Name: Jasper Doest Image Name: Untitled Year: 2024 Image Description: Elephants charge through Livingstone?s narrow streets, their towering figures trumpeting into the night. Altered habitats mean they emerge from the national park at dusk to seek food within Livingstone. A nighttime curfew, urging the community to stay indoors, aims to reduce human-wildlife conflict. Series Name: In the Footsteps of Giants Series Description: The delicate equilibrium between humans and elephants in rural parts of Zambia is being disturbed as both populations vie for limited resources. The expansion of settlements and unsustainable agriculture is encroaching on elephant habitats, jeopardising the well-being of both human livelihoods and the elephant population. The question arises: can humans and elephants coexist? These problems have been escalating in the past decade, and with the expectation of increased droughts due to our warming climate, establishing transfrontier wildlife corridors becomes essential. However, the establishment of these corridors faces challenges posed by settlements, agriculture and infrastructure, which results in daily human-wildlife conflict. As these persistent issues continue it is increasingly evident that the local community plays a vital role in fostering a harmonious coexistence between humans and elephants. Developing economically and socially viable models for coexistence within the local community will be crucial for the long-term survival of both elephants and humans. Copyright: ?
