Coffee (Coffea canephora) is the principal cash crop and the country’s largest agricultural foreign revenue earner in Uganda. Previous surveys confirmed that coffee grown in central Uganda was largely depending on bee pollination to set fruit set. Despite its high contribution to the economics of agricultural sector in Uganda and despite its great dependency to bees for fruit set, it is not clear if small-scale farmers are aware of the importance of managing farm-landscapes for pollination services conservation to increase coffee yield. The aim of this study was to assess farmers’ perceptions and knowledge of the importance of pollinators and pollination services conservation for coffee production enhancement. The main hypothesis was that small-scale coffee growers were not aware of the relevance of pollination services for coffee production. Farmers’ surveys were conducted in coffee-banana farming systems in central Uganda. It was found in this study that more than 90% of interviewed farmers were not aware of the role played by bees in coffee yield increase. Farmers were not willing to manage their lands to protect pollination services, particularly because they considered pollination service as an unsolicited “free service”, or as a “public good”. Farmers were not aware of the role of semi- natural habitats serving as reservoir (hiding points) for pollinators in the surrounding of coffee fields. However, they were aware of some ecosystem services delivered in the coffee- banana farming system such as planting shading trees. Only 3.3% of respondents believed that placing beehives in coffee farms could increase the yield. The study recommended the increase of the awareness of small-scale coffee growers on the importance of pollinators to increase coffee production. It is recommended that future management of pollination services are built on improving farmers’ indigenous knowledge and on adequate understanding of the ecology of the local pollinator species.

Beekeeping is one of the recommended approaches in the implementation of poverty alleviation programs in rural areas of Burkina Faso. However, plants that are important in beekeeping have not been identified. The use of parts and organs of plants by beekeepers and their methods of harvesting remain unknown. These limit the conservation efforts of these important plants and affect beekeeping development. The study was carried out in the south-central, eastcentral regions and in Comoé and Boucle of Mouhoun regions ofBurkina Faso. The objective of the study was to identify the plants species used by traditional beekeepers, the different uses made of these plant parts and organs and then to discuss the impact of these activities on the survival of the plant resources. An ethnoapiculture survey was conducted in the main apiculture zone of Burkina Faso, using semi-structured interviews. The methodology of botanical coherence or convergence was applied to classify botanical species. Results showed that 35 botanical species were used in traditional beekeeping. The use of plant parts or organs in traditional hives construction represents 55%, attraction of wild swarms in new beehives is 37.50% and use as a torch or as a smoker, 7.50%. The barks are the organs most used. Trees are botanical type most used. The results are not exhaustive and therefore other additional studies need to be carried out. In order to sustain the use of these important plants, their growing in nursery and their planting in the field are recommended.
