Abstract: This paper assesses maize-coffee-banana agro-ecosystems’ resilience to damage as well as computing the social-ecological vulnerability index to climate change on the southern slope of Mount Kilimanjaro in Tanzania. The study focused on identifying agronomic practices and assessing their impacts on agro-ecosystems’ resilience; examine the socio-economic status of the farmers in the region and its impacts on agro-ecosystems; and examine the agro-ecosystems’ natural resilience a...
Abstract: Management of the natural resource of a drainage basin primarily for the production and protection is considered essential for soil and water conservation. Despite an increase in CDF allocations, watershed management approaches are not integrated in local development projects to realize sustainability. The study assessed the need and ways of considering watershed management approaches in CDF projects. Key objectives included to determine the relative importance of factors that infl...
Abstract: This study assessed the socio - economic importance of Liriomyza Leafminers (LMF) of vegetable crops in Northern Tanzania focusing on farmers’ knowledge, attitude and practices towards management of this insect pest in their fields. A total of 117 households were interviewed for primary data collection. Desk study was used for secondary data collection. Findings revealed that majority of respondents were educated up to primary level and lived in households with 1 – 10 individua...
Abstract Houseflies are pest in homes, dairies, barns, poultry houses, recreation areas and food processing sites. The study is to evaluate the susceptibility of Musca domestica to deltamethrin, cypermethrin and DDVP insecticides. Topical bioassay was used to perform adulticidal test, while dipping method was used for larva and pupa, different concentrations were used which ranges from 0.5ml/L-10.0 ml/L for larvae and pupae while 5.0 µL/fly-50.0 µL/fly was used for adult Musca domestica. Th...
ABSTRACT Plastics are synthetic polymers made by chains of carbon atoms with hydrogen, oxygen, nitrogen, Sulphur built around the carbon chains (Shah et al., 2008). These polymers are involved in every domain of our lives ever since its production began from the year 1950’s, plastics have been produced at an augmented rate to meet day to day demands of the entire world. Accumulation of plastic waste in the environment causes chemical pollution when methods like incineration are used to get ...

Africa is the world's second-largest continent, covering an area of approximately 30.2 million square kilometers. It is home to 54 countries, each with its unique culture, history, and natural resources. The continent is rich in natural resources, including oil, gas, minerals, and agricultural commodities, which are in high demand globally. The African continent plays a significant role in the global commodity trade, providing the world with critical raw materials. Africa is a leading produce...
ABSTRACT Laboratory experiment was conducted to determine the insecticidal activity of leaves and stem bark powder of Sodom apple (Calotropis procera) and optimum concentration for the management of maize weevil (Sitophilus zeamais). Actellic dust 50g was used as positive control and untreated Maize seeds serving as negative control. The experiment was laid in Completely Randomized Design (CRD) comprising of Leaf powder (1, 3 and 5 g), stem bark powder (1, 3 and 5 g), Actellic dust and contro...
ABSTRACT Alum (potassium aluminum sulfate-K+Al3+ (SO42-) 2), ferrous sulfate (Fe2+ SO42-), ferric chloride (Fe2+2Cl-) and ferric chloro-sulfate (Fe2+Cl-SO42-) were commonly used as coagulants. However, a possible link of Alzheimer’s disease with conventional aluminum based coagulants and other adverse bioaccumulation cases associated with heavy metal have become an issue in wastewater treatment. Hence, special attention has shift towards using biodegradable polymer like chitosan in treatmen...
Electropolymerization and redox behavior of lignin composites were characterized by cyclic voltammetry (CV), electrochemical quartz crystal microbalance (EQCM), and Fourier transform infrared spectroscopy (FTIR). Oxidation of lignin (LG) composites mixed with different polymers such as; Poly (o-phenylenediamine) (POPDA), Pyrrole (Py), 4-amino-3-hydroxynaphthalene-sulfonic acid (AHNSA) on working glassy carbon electrode (GCE) were performed by cyclic voltammetry in a three-electrode ...
This project titled Bioaccumulation of persistent pollutants in Clarias gariepinus gotten from Ogu Creek is based on ecotoxicology and utilized African catfish (Clarias gariepinus) as a model in estimating the bioaccumulation of pollutants in living tissues of organisms in Ogu creek which is a point of poorly treated effluent discharge. The persistent pollutants include Zn, Cr, Cd, Pb, Mn, and Total Petroleum Hydrocarbon (TPH). The concentrations of the heavy metals were determined with Atomi...
The agenda of the United Nations Sustainable Development Goal and the international Energy Agency tailored towards addressing the global crisis of climate change mitigation (depletion of the Ozone layer is of great concern due to the adverse effect of carbon emission activities which has proven to be pungent, lethal, non-degradable with zero socio-economic relevance). Hence, this research study under a feasibility check investigated the possibility of synthesizing green ferrofluid from pl...
