Forests are home to many flora and fauna species. Forest flora have been very important to man and sustainability of forest ecosystem. Forest flora provides provisional, regulatory, protective and cultural services. These services have been the foundation of civilization and development. Local communities depend on these natural resources for livelihood generation and cultural services. Local communities have been using medicinal plants to cure different ailments. In this study, an ethnobotanical survey was conducted to document medicinal plants diversity and use in forest fringe communities. The study adopted a method used by Martin in 1995 on Ethnobotanical reviews of medicinal plants. Ethnobotanical information was gathered through structured questionnaires administered to 57 inhabitants constituting key informants, community leaders, and household heads who are believed to have vast indigenous knowledge of medicinal plants. The snowball technique was used to identify respondents in communities around the Kasewe forest. For the diversity of medicinal plants use and associated indigenous knowledge, a plot of size 25 m × 25 m was demarcated with a linear tape and ranging poles in the different habitat types in the study area. Sampling was stratified based on the size of habitat types. A total of 10 sample plots comprising of 4 plots in the closed forest;3 plots in disturbed areas, 2 plots in farmland, and 1 plot in the grassland were studied. A total of 3377 individual plant stems were documented comprising of 84 individual species belonging to 53 families and 78 genera. Of the 84 individual plant species, 42 were medicinal. The most dominant family was Malvaceae. Tree species were the most dominant life form representing 32.14% followed by shrubs 30.5, herbs 26.8% and climbers 10%. Majority of the plant species are of little conservation concern and few have been categorized as endangered and vulnerable that need special conservation attention. Species with the hi

The success of any waste management system requires accurate and up-to-date data on quantity, composition of waste. Waste generation data from household are needed to address issues relating to municipal solid wastes such as management method, performance improvement, policy, regional and local planning, administrative, cost accounting, design and operation of landfill facilities and environmental quality. This study was conducted to provide empirical data on generation rates, quantity and composition, management practices, challenges and strategies from urban household. Waste collection, weighing, questionnaires survey and field observation were methods used during the study. Waste was collected and weighed from 60 households using multi-stage sampling technique for seven days. Questionnaires were analyzed using Statistical Package for Social Sciences version 20 and Excel. A total of 1125.2 kg of waste was recorded. The average household waste generation was 3 kg per day with per capita generation rate of 0.41 kg/cap/day. The compositional analysis showed that Organic (53%), Plastic (11%), Textile (6%), Metal (2%), Glass (1%), Paper and Cardboard 4% and others (22%). Solid waste management practices are very rudimentary. Burning (53.7%) and Open Dumping (30%) were found to be the most commonly used method of disposal with very limited collection service (33.3%) and segregation. The most challenges faced by households were communal disposal area (66.7%) and waste service providers (21.7%) storage bins (11.6%). Waste to energy (48.3%) and compositing (23.3%) were the most considered option for waste management by the respondents.
