An effective model for community-based conservation around authorized fishing settlements inside a devolved Wildlife Management Area in southern Tanzania

Abstract

AbstractWildlife Management Areas (WMAs) represent a relatively new institutional model for devolved, locally-led conservation in Tanzania, in which local villages set aside part of their land for wildlife conservation and manage that resource collectively, so that their stakeholder communities can collectively leverage economic and social benefits from income-generating activities like tourism. This study examines the relationship between community-defined land use plans andde factoland use practices, and the influence of the latter on the relative abundance and distribution of large wild mammals in a across the Ifakara-Lupiro-Mangula (ILUMA) WMA, which acts as a key buffer zone between Nyerere National Park (NNP) to the east and adjacent stakeholder villages to the north and west. All observed signs of wildlife and human activity were recorded across 32 locations inside ILUMA and in the permanent settlements and national park that respectively border it to the west and east. Across much of ILUMA WMA, in areas where agreed land use plans were not adhered to, rampant cattle herding and land clearing for agriculture were associated with reductions in wildlife richness and biodiversity, as well as overall ecosystem integrity. Although human settlement was also generally associated with reduced natural ecosystem integrity, some important exceptions to this rule illustrate how sustainable livelihoods for local people that are based on well- managed natural resource harvesting practices may actually enhance conservation effectiveness: Three authorised human settlements within the WMA, where fishing was the primary permitted livelihood and local communities collaborated with the WMA management, were surrounded by pristine land cover with thriving terrestrial wildlife populations. Correspondingly, the best conserved parts of the WMA not only included those closest to the boundary with the national park to the east, but also these fishing villages along the riverbank to the north, where compliance with agreed land use plans was most rigorous. Overall, this study documents a useful example of how a devolved conservation area may conditionally host resident local communities undertaking selective natural resource extraction activities and collaborate with them to achieve effectivede factoconservation practices.
