The wetland ecosystems on Mount Cameroon’s eastern slope, known for their agroecological significance and biodiversity, are facing potential threats such as heavy metal and bacterial contamination due to poor waste management systems and anthropogenic activities. A study was conducted to quantify the heavy metals and bacterial loads in Solanum scab...

The overall objective of this study was to determine the ecological status of some freshwater resources in Limbe Municipality with respect to land use land cover changes, water and soil quality. Ecological surveys were carried out to assess the impact of land use and land cover changes on the water quality of some water catchments in Limbe municipa...

Physicochemical parameters, chlorophyll a (Chl a) concentration, and phytoplankton community structure were assessed in the Wouri estuarine mangrove sector of the Douala Bassa Industrial Zone of Cameroon over two seasons. Three sets of water samples were collected from 10 sites for these analyses. Some physicochemical parameters were measured in si...

Objective: Contamination by heavy metals in soil, water, and agricultural products is a significant concern, particularly affecting wetland ecosystems. This investigation aimed to assess the levels of heavy metals (Pb, Cd, Hg, Cu, As, Zn, and Ni) and nutritional values in three highly cultivated leafy vegetables (Talinum fructicosum (L.) Juss., Ver...

Aims: This study was designed to assess quantitative estimates of epiphyte biomass and diversity on the dominant macrophytes in two rivers in the Eastern flanks of Mount Cameroon. Place and Duration of Study: Two sets of water samples were collected at the top 10cm of the rivers for nutrient and chlorophyll a determination. A single preliminary col...

Abstract Inland aquatic ecosystems cover 0.1%–3.0% of Earth’s surface. They provide different ecosystem services to the area, such as drinking water, transportation, and hydropower generation. However, increasing land use changes threaten their ecological integrity. This study aims to assess land use and land cover change and their impact on stream...

Land use change detection is often conducted to critically discern trends, causes, and their impacts on the landscape to enhance decision-making for conservation of biodiversity and ecological functions. The objectives of the study were to evaluate Land Use and Land cover changes in Tubah Sub-Division, Cameroon, from 1986 to 2017, and to determine...

Lacustrine ecosystems have not been widely assessed for heavy metal contamination and associated health risks; yet, they could be accumulating these contaminants to the detriment of aquatic organisms and communities relying on them for various aspects. The water quality index (WQI) and concentrations of heavy metals including As, Cd, Co, Cu, Cr, Fe...

Inadequate pesticide application practices have many implications on human and environmental health. This research aimed at assessing pesticide risks on bees, non-target arthropods (NTAs) and earthworms, using PRIMET (Pesticide Risks in the Tropics to Man, Environment and Trade), a pesticide risk model, in the western highlands agro-ecological zone...

Aims: Afzelia africana is one of the most popular woody forage resources used by pastoralists in northern Cameroon in the dry season. In order to contribute to the sustainable management of this species in the Benoue National Park (BNP) and its surroundings, a study was conducted on the perception and conservation of this species, the knowledge of...

Indiscriminate use of fertilizers by vegetable growers and poor water quality of irrigational water characterize vegetable production in most parts of Cameroon. The concentrations of As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn in the soil, cabbage and carrot cultivated in Santa, North West Region, Cameroon were assessed to determine potential ecologi...
