International Journal of Environment and Climate Change <p style="text-align: justify;">A sustainable world is one in which human needs are met equitably without sacrificing the ability of future generations to meet their needs and without harm to the environment and ecosystem function and service. Meeting this formidable challenge requires a substantial effort under climate change impact, economic development and population growth. <strong>International Journal of Environment and Climate Change (ISSN:&nbsp;2581-8627)</strong> aims to publish original research articles, review articles and short communications. This is a quality controlled, double blind peer-reviewed, open access INTERNATIONAL journal. It has long been recognized that the long-term viability of natural capital is critical for many areas of human endeavour under climate change impact. The aims are to support engineering science research with the goal of promoting sustainable development with environmentally benign engineered systems that support human well-being and that are also compatible with sustaining natural (environmental) systems.</p> en-US (International Journal of Environment and Climate Change) (International Journal of Environment and Climate Change) Wed, 27 May 2020 04:25:38 +0000 OJS 60 Preliminary Screening of Polybrominated Diphenyl Ethers (PBDEs); Decabromodiphenyl Ether (BDE-209) and Tetrabromobisphenol-A (TBBPA) Flame Retardants in Municipal Dumpsite in Delta State, Nigeria <p><strong>Aims:</strong> This study is aimed at determining the concentration of two widely used BFRs; Decabromodiphenyl Ether (BDE-209) and Tetrabromo Bisphenol-A (TBBPA)<strong>&nbsp;</strong>in sediment and leachate samples.</p> <p><strong>Place and Duration of Study: </strong>Field sampling were carried out from five major dumpsites around Warri Municipality, Delta State, Nigeria. Analyte extraction was done in 2017 at the Science laboratory, Federal University of Petroleum Resources, Effurun Delta State, Nigeria and quantification done in Switzerland by Bachema Analytical Laboratories in 2017.</p> <p><strong>Methods: </strong>Three soil samples were collected from each site 15cm from the soil surface. Also, three leachate samples from three different trial pits done for each site. Collected soil samples were stored in glass bottles and labelled. While the leachate samples are stored using glass containers and labelled. The BFRs were extracted using Aceton and cyclohexane for each soil matrix and cyclohexane for the leachate samples, then the extract was analysed using GC coupled with an ECD supplied by Thermo Trace GC Ultra, Italy.</p> <p><strong>Results: </strong>The results showed the average concentration for TBBPA in the sediments was 0.0234 g/kg and that of the BDE-209 was recorded as 0.1828 g/kg. Results from the leachate sample were below the detectable range of the analytical equipment, TBBPA (0.02 g/kg) and BDE (0.1 g/kg). There is no statistical difference between the mean concentration of TBBPA for the sediment in each of the locations (<em>P</em>&gt;.05) and no difference (<em>P</em>&gt;.05) for BDE-209 for the sediment in each of the locations (<em>P</em>&gt;.05).</p> <p><strong>Conclusion: </strong>Findings from this study holds that the concentration of TBBPA and BDE-209 in sediment is higher when compared with concentrations presented in other literatures studied in this report and this calls for immediate action due to the health risk associated with exposure in these municipalities.</p> Oghenekohwiroro Edjere, Chukwunonso Elvis Stephen ##submission.copyrightStatement## Wed, 27 May 2020 00:00:00 +0000 Bio-management Options for Ecosystem Services, Carbon Sequestration and Climate Change Adaptation in Saline Environment <p>Nearly one billion hectares of arid and semiarid areas of the world are salt affected and remain barren due to salinity or water scarcity. These lands can be utilized by adopting appropriate planting techniques and integrating trees with tolerant crops, forage grasses, oil yielding crops, aromatic and medicinal plants. Biosaline agroforestry provides various ecosystem services such as the improved soil fertility, carbon sequestration, and biomass production. Provisioning services relating to biomass production have been well studied in different biosaline agroforestry. Tree plantations and agroforestry enrich the soil in organic matter and exert a considerable ameliorative effect on soil properties. The soil microbial biomass serves as a useful indicator of soil improvement under salt stress. By integrating trees with the naturally occurring grassland systems on highly sodic soils, the soil organic carbon content increased from 5.3 Mg ha−1 (in sole grass) to 13.6, 10.9, and 14.2 Mg ha−1, when <em>Dalbergia sissoo, Acacia nilotica</em>, and <em>Prosopis juliflora </em>trees were introduced with grass<em>. </em>The strip-plantations of clonal <em>Eucalyptus tereticornis</em> sequestered 15.5 t ha<sup>–1</sup> carbons during the first rotation of 5 years and 4 months. The soils of biosaline agroforestry could store 25.9–99.3 Mg C ha−1 in surface 0.3 m soil. Maintaining the stores and sink of carbon in agroforestry could play a key role in climate change mitigation as well as help in adaption changing environmental conditions.</p> Mukesh Kumar, S. R.
