Abstrakt: Neglected and underutilized plant species (NUS) in Tanzania are maintained by socio-cultural preferences. However, a majority remains inadequately characterized and neglected by research and conservation initiatives. Over long time ago, the NUS have been part of the major component in the food systems of local communities especially in the dryland areas to overcome challenges brought about by uncertain climatic conditions. This study documents the NUS diversity and indigenous knowledge on their availability, agronomic and cultural practices in the Semi-arid zones of Tanzania to verify their economic potentials and promote their sustainable utilization for climate change adaptation as well as natural resources conservation. The study involved field plant identification, quantification and participatory rural appraisals (PRAs). The results indicate that the study regions have very rich diversity of NUS contributing significantly to the people's adaptation to drought conditions and food shortages in the areas. The NUS in the studied regions had varied uses including food and medicine. A majority of the consulted farmers in the study area indicated that the NUS utilized in the areas were either minimally cultivated on farms, freely obtained from the wild or grew as weeds in the farmlands. Despite the potentials for NUS in contributing to climate change adaptation in the areas, so far there have been no efforts geared towards their sustainable utilization and conservation. It is observed that promotion of NUS through improved packaging and marketing could contribute to the economy of the local people who have access to NUS in the area and therefore enhance resilience of semi-arid communities.
