Automated species identification for camera trapping in the Iona Skeleton Coast Trans-Frontier Conservation Area

Abstract The Iona Skeleton Coast Trans-Frontier Conservation Area (TFCA), straddling the border between Angola and Namibia, has suffered through decades of civil war and poaching. While this history has been detrimental to the community of large mammals in the TFCA, data collected on the mammal populations are insufficient to enable effective management. Survey methods such as aerial counts and community-based monitoring have various shortcomings. Therefore camera trapping, which has become ...

Assessment Of Changes In Land Cover And Forest Composition And Structure In Okongo Community Forest, Namibia

Abstract Land cover refers to the observed vegetation, structures, or other features that cover the land such as closed forests, open forest, woodland, grasslands, bushland, and settlements. Land cover change is one of the serious threats to the forests and woodlands of Namibia, and it is mainly triggered by forest resource utilization and conversion to agriculture by local communities. As one of the mechanisms to control land cover change, Namibia introduced the Community Forests (CF) progra...
