Bamboo diversity and carbon stocks of dominant species in different agro-ecological zones in Cameroon
Bamboo is of ecological and socio-economic importance in the world. However, knowledge on its potential in climate change mitigation remains superficial in Cameroon. The present study identified bamboo diversity and estimated carbon stocks of the dominant species in Cameroon. Ground truth method and local informants were used for a bamboo species survey in five Agro-ecological zones (AEZs). Twenty-two circular plots of...

Advancing climate change adaptation in Uganda’s agricultural programming for sustainable development: Key milestones and constraints
Climate change remains a crucial threat to sustainable development, particularly to the farming communities, which are more vulnerable to climate impacts. Uganda has made commendable steps in building an institutional framework for addressing climate change. However, the framework remains scattered in several documents making it difficult to track and conceptualize. This paper provides a one-stop center for...

Assessment of air pollutant emissions from healthcare waste incinerators of different design features
The aim of this paper was to e valuate the levels of gaseous emissions from four different healthcare wastes incinerators in three regional hospitals and one national hospital in Dar es Salaam, Tanzania. The incinerators studied differ in terms of capacity (kg/h) and design features. Five gaseous air pollutants (CO, CO2, NOx, and SO2) were analyzed in the sampled flue gases using a portable desktop combustion gas...

Occurrence dynamics of nitrogen compounds in faecal sludge stabilisation ponds in the Tamale Metropolis, Ghana
Faecal sludge, with richness in soil nutrients represents an important resource for enhancing soil productivity. In this study, the occurrence dynamics of nitrogen compounds NH3, NO2- and NO3- in engineered waste stabilisation ponds in the Tamale metropolis was monitored for 5 months in the dry season. Four treatment ponds were divided into three units: Influent point, midpoint and effluent point for sampling purposes....

Assessment of the phytoremediation capabilities of bracken fern (Pteridium aquilinum) for the remediation of heavy metals (Pb, Ni and Cd) contaminated water
This study was carried out to investigate the potential uptake of heavy metals (Pb, Ni, and Cd) by Pteridium aquilinum plant from aqueous solutions. The whole plant strands were cultured in 36 experimental pots containing 5, 10 and 15 (mg/L) of Pb2+, Ni2+ and Cd2+ aqueous solutions. The plants were harvested after 24, 48, 72 and 96 hours of exposure and segmented into leaves, stem and root, respectively. The heavy...
