ABSTRACT Petroleum production causes a wide array of sustainability impacts, including a large share of global greenhouse gas and other emissions. It has also been associated with wider environmental and human rights impacts during drilling and refining, and occasional but destructive toxic releases from spills and accidents. This project aims at making petroleum production activities more environmentally sustainable, by finding a beneficial use of flared gases. Gas flaring is one of the top...
In South Africa the green macroalga Ulva armoricana is the main species of macroalgae cultured. The species is currently the largest aquaculture (2884.61 tonnes) product by weight with a corresponding capacity for biogas (CH4) production. We have shown that biotransformation of U. armoricana to Liquefied Petroleum Gas (LPG) is viable and economically feasible as a clean fuel. pH toxicity tests showed that U. armoricana can be used as a health index, under potentially increased CO2 concentrati...

Quantitative data were collected using semi-structured questionnaires, while qualitative data was collected via personal observations, desk research, a...
Abstract: Evaluation of the biosecurity of layer farms is essential for successfully controlling and preventing poultry diseases. The objective of this study is to evaluate the biosecurity of layer farms in Sierra Leone using the Biocheck. UGent scoring system. This online biosecurity evaluation tool assesses the farm's biosecurity compliance. The data was collected from 38 layer farms in four provinces and one area in the country. The data were encoded online to provide ratings for each farm...
Climate change is having a negative influence on agriculture and livestock production systems. This study aims to assess livestock farmers’ perceptions and adaptive responses to climate change in the Koinadugu area of northern Sierra Leone. A sample of 126 livestock farmers was selected from four chiefdoms. The data were collected using a semi-structured questionnaire and meteorological time series data. The Statistical Package for Social Sciences (SPSS) version 23.0 and excel were used to ...
The poultry industry worldwide suffers significantly due to climate change, which may affect the chicken protein source. The study examined backyard poultry farmers' awareness, perceptions, and responses to climate change in Tonkolili, Sierra Leone. Data were collected from 232 backyard poultry farmers using a semi-structured questionnaire. The data were analyzed using SPSS 23.0 Software. According to the respondents' socioeconomic profiles, the majority of farmers (53.4%) were between the ag...
The poultry industry globally provides chicken meat and eggs, the most significant protein sources among animal foods. The industry is grappling with the effect of climate change which causes heat stress and harms the performance and welfare of the chicken. Heat stress has been the most significant environmental stress challenging the global poultry industry, as chickens only tolerate a narrow range of temperatures during heat stress. This review aims to assess the impact of heat stress on ch...
Slaughterhouse workers are more susceptible to zoonotic disease infections from cuts and bloodletting, spreading blood-borne pathogens to societies. Adopting biosecurity measures by slaughterhouse workers in their daily tasks can lower the risk of spreading zoonotic diseases while improving food safety. This study aims to examine slaughterhouse workers' awareness of biosecurity, their perception of the efficiency of biosecurity measures in reducing zoonotic infections, and, most crucially, th...

A multistage sampling procedure was employed to select the respondents for the study from five districts that make up peri-urban areas of Dutse. Data were collected through the use of structured questionnaires administered to 165 respondents out of which only 159 were found to be useful. Data collected were analyzed using frequenc...
Cocoa (Theobroma cacao) contributes significantly to Ghana’s GDP and has made Ghana a recognized leader in the cocoa industry. However, there are myriad problems associated with Ghana’s cocoa bean quality. One such problems stems from farmers paying less attention to the required postharvest activities (fermentation and drying) which contributes significantly to bean quality losses. *is study investigated the effect of the duration of the traditional heap fermentation period and differ...
Under rain-fed conditions, perfumed rice production in Northern Ghana is associated with high paddy cracking during milling. In this study, 4 perfumed rice varieties, 6 staggered planting times, 6 staggered harvesting cycles, and staggered storage duration from harvest to six months of storage were used in a randomized complete block design to identify the best combination of factors that are associated with low cracking in rice production. )e experiment was laid out in a randomized comple...
An experiment was conducted at the University of Education, Winneba, Mampong-Ashanti campus to determine the effect of some cowpea lines as green manure on the growth and yield of carrot in root-knot nematode infested soil. Randomized complete block design with five treatments and four replications was used. Thetreatments were cowpea lines IT97K-570-18; IT97K-566-18; and IT00K-1150 as green manure, N.P.K (15, 15,15) and control. The results showed negative correlation between root-knot nema...
