Abstract: Socio-economic factors influencing stakeholder participation in forestry activities in Benue State were assessed to establish the indicators of participation in forestry activities in the State. Thirty percent of Local Government Areas from each of the 3 geo-ecological zones of the State were randomly selected for the study. A semi-structured questionnaire was administered among 420 stakeholder groups to elicit information on factors influencing their participation in forestry activities. Data collected were analyzed using descriptive and inferential statistics such as binary logistic regression and Kruskal-walis. The study showed that most forest sector actors in the area were males......

Abstract: This study was carried out to look at the diversity and abundance of fish species in some selected riverine wetlands of the Upper Benue River Basin. The study was carried out for a 6 month period (July to December 2016). Sampling was by direct observation of the fish at the landing sites. Frequency counts, percentages were used to analyze the fish species composition and abundance while ComEcolPaC (a Microsoft Excel 2003 based program) was used to analyze the variation in the diversity indices. A total of 26 species from 16 families were observed in the riverine wetlands studied and the most diverse groups of fish species were: Schilbe spp with 10.95%.....

Abstract: The pollution of aquatic ecosystems with heavy metals has become a worldwide concern and more so in developing countries. This is because of their ability to bioaccumulate in aquatic organisms and especially in fish which is a source of livelihood for human populations. This study assessed heavy metal contamination (Pb, Cd, Cr, Cu, Zn and Mn) in muscles of Cyprinus carpio from Masinga dam for a period of twelve months. The fish samples were collected on monthly basis using gill nets from five sampling sites in the dam. The fish samples were then taken to the laboratory where fish muscles were extracted, dried and acid digested for heavy metal analysis. Heavy.....

Abstract: A study aimed at removing fluoride from natural water through adsorption technique wascarried out using dolomite [CaMg(CO3)2] as a sorbent. Batch experiments were conducted using dolomite in raw form and in calcined form to enhance the activity of calcium and magnesium for the adsorption of fluoride ions present in groundwater. Experiments were conducted using different dosages of dolomite for different concentrations of fluoride. It was observed that at 850°C, the activity of dolomite was high to form complex with fluoride, whereas adsorption through raw dolomite was insignificant. No significant change in TDS in the water samples was observed, while a rise in pH was observed when analyzingcalcined dolomite. This could be a cost-effective method to remove fluoride from water for consumption..

Abstract: Air pollution tolerance indices (APTI) were analysed in 2 plants (Telfairia occidentalis and Ocimium gratissimum) growing on farm sites surrounding three industries: Lead-acid battery factory (experimental site 1), Petroleum products factory (experimental site 2) and PVC Pipes and Cement packaging factory (experimental site 3) with a non industrial site selected as control site all in Nnewi, Nigeria. Leaf relative water content, Ascorbic acid, Total chlorophyll and Leaf extract pH were analysed and used to calculate the APTI values. The two plants growing in experimental (polluted) sites had significantly higher (p< 0.05) APTI than those in the control site with their.....

Abstract: Lingbao jujubewhich contains polysaccharide, an important biological active material, has high nutritional and medicinal values. In this experiment, polysaccharidewas extracted fromLingbao jujube. The effects of solid-liquid ratio, extractiontemperature, extractiontime and extraction times on the extraction yield of Lingbao jujube polysaccharide were investigated by single factor test. The extraction process conditions were optimized using orthogonal test. The results of single factor experiment showed that the extraction rate of polysaccharide was higher when the solid-liquid ratio was less than 1:6 g/mL, but the difference was not significant.When the extraction temperature was between 60 and 100°C, the extraction rate of polysaccharide increased with the increase.....

Abstract: In this experimentcollagen was extracted from the squid scales by water extraction. The content of collagen in the extract was determined by spectrophotometry. The effects of extraction temperature, ratio of material to liquid, pH value and extraction time on the extraction rate of collagen in carp scales were studied. From the single factor test, The better parameters for extracting collagen by water extraction were extraction temperature of 20～30°C, ratio of material to liquid of 1:20～1:30 (g/mL), pH of 5～6 and extraction time of 5h. Based on the above, three factors including extractiontemperature, solid-liquid ratio and pH value which had great influence on the extraction rate of collagen were selected to carry out orthogonal test. The optimum process parameters for water extractionof collagenwere as follows: extraction temperature of 20 °C, pH value of 6 and the ratio of material to liquid of 1:20 (g/mL)..

Abstract: India has a vast coastline, regularisation of activities for the protection of the coastline is one of the major concerns of the government of India. The sensitivity of the zone makes it prone to damage by the changes in the climate. Coastal Zone regulation notification acts a deterrent against these climatic influences. Protection of coastal ecosystem needs sustainable plans. Human survival is in many ways dependent on the productivity of these coasts, thus, it is crucial for us to preserve our coasts. This paper analyses the coastal zone regulation notified by the government for the protection of coasts with special emphasis on the recent notification of 2018. The author finds the 2018 notification as a sham. The coastal protection is imperative and in such vulnerable times, the government has come.
