Abstract
This study delves into the pattern and level of development of two adjacent border communities of Lagos and Ogun States, Nigeria to compare the effect on rental values of residential properties in the two communities. The study attempted to find out if there are significant differences as well as definite relationship between the values. Questionnaires were distributed to two groups of respondents which are 84 estate surveying and valuation firms in Ikeja, Lagos and 152 residential property owners/residents in the two communities. Data were analysed with statistical tools such as tables, percentages and mean. Student’s t-test statistics was used to ascertain the difference in rental values while Pearson coefficient of correlation was used to establish the degree of relationship. The importance of factors influencing rental values was determined using the relative importance index. Analysis were presented in percentages, tables and charts and then discussed. Result showed that there are significant statistical differences in rents of the two communities despite the proximity. It was further observed that neighbourhood density and level of infrastructure development play vital roles in the gaps observed in rental values. However, the Pearson correlation coefficient revealed that there is a relatively strong positive correlation between rental values of properties in the two communities. The research therefore concluded that for property market on the Ado-Odo/Ota side of the emerging Lagos megacity to attain its full potential, there is the need for major urban renewal, investment in physical and economic infrastructure via partnership with private sectors and property owner in the communities.

Abstract
In this work, the impact of selected atmospheric parameters on attenuation of terrestrial and satellite signals over George, Western Cape in South Africa for the purpose of planning reliable and resilient free space optical communication links has been presented. The meteorological parameters data (visibility, temperature, rainfall rate, relative humidity, pressure, wind speed and wind direction) were obtained for ten years (2010 – 2019) from the South African Weather Service (SAWS). Total attenuation for the studied location was calculated from attenuation due to aerosol scattering, attenuation due to rain and attenuation due to scintillation. Three different wavelengths namely: 850 nm, 1200 nm and 1500 nm within the optical windows were used in calculating the wavelength dependent functions (attenuation due to aerosol scattering and attenuation due to scintillation). The result shows that attenuation due to rain was observed to account for 58% of the total attenuation and it is wavelength independent. Attenuation due to rain based on subtropics model was found to be about half of the calculated value based on temperate model. Further result shows total attenuation for worst visibility period (summer) throughout the year in the studied location is 7.7 dB/km (aerosol scattering: 0.53dB/km; rain: 4.5 dB/km and scintillation: 2.7 dB/km) at 850 nm. Overall results will be applicable in the area of the design and implementation of a reliable free space optical (FSO) links in the studied location.

Published: March 2021

Abstract
Global warming is sketching the isobars on weather maps in a different way, owing to new patterns and their climatic imprint. Climatological reports have shown that atmospheric pressure fluctuations in the past five decades has strong affiliations with human stimulus. Any infinitesimal change in air pressure could produce a dramatic climatic effect, such as wind, precipitation, diurnal perturbations and storms. Pressure in air is the pointing device for atmosphere’s circulation, and consequently, determines how humidity circulates. Progressive studies on air pressure from both experimental and theoretical sources have corroborated with each other. The potential for atmospheric pressure is a function of the individual sum of oxygen, carbondioxide, water vapor, nitrogen, and noble gases in air. Although, it is difficult to predict the life span of these atmospheric gases, we cannot assume that the abundance of either of these gases has remained constant over geologic time. This study focuses on analyzing weather changes in Ikogosi SW Nigerian, in conjunction with pressure for almost four decades, using curve fitting regression analysis and statistical methods relative to direct plots. The result reveals exponential trends of growth in pressure-temperature measurement indicative of weather change. In view of this, recommendations are given based on indices of measurement shown by occurrence and the force of atmospheric pressure.

Published: March 2021

Abstract
Studies recognized that construction waste constitutes about 30-40% of the overall solid waste deposited at the landfill sites worldwide, and to have impact on our personal lives and the entire world around us. This research studied building life cycle and waste generation by building projects in southwest Nigeria by the use of structured questionnaire applied to representatives of professionally registered firms of the Nigerian construction industry in the region. A total of four hundred and three (403) questionnaires were randomly administered to the professionally registered firms within the study area, out of which only two hundred and sixty-one (261) of those returned were considered valid and usable. The retrieved data was profiled and rank using the 5 points Likert scale. The study found that post-construction stage activities had the greatest affinity for material waste generation with the highest mean score of 3.5172 and followed by the construction stage activities with the mean score of 3.0672 indicating that waste generation at this stage is moderate. Based on this, the study concludes that there is a need to develop incentives that will encourage the industry professionals to imbibe waste prevention and minimization strategies that will help limit waste generation by the different building life cycle stages.

Published: March 2021

AbstractMicroplastics are pervasive contaminants that have attracted the attention of researchers over the last decades. Studies have detected and investigated different sizes of microplastics in the environment. However, the methods used for sample collection and quantification of microplastics for similar environmental matrices differ, based on the resources and equipment available to the researchers. This variation makes the comparison of results from different regions or researchers challenging. This paper presents a review of some of the methods that have been employed in microplastics quantification. We highlight the advantages and disadvantages of some of the methods and recommend that standardized methods need to be developed in order to simplify inter-study comparison.

Published: March 2021

Abstract
One of the challenges of climate change in most coastal regions of the world is sea-level rise. This is of serious consequence as the coastal zone plays host to a large human population, abundant natural resources, and several ecosystem services. To alleviate the effect of climate change, proper planning of the coastal area is necessary to enhance the process of adaptation. This study attempts to project an estimate of the rate of sea-level rise along the coastline of Lagos, Nigeria in various time slices, i.e., 2025, 2050, 2075, and 2100 for all 4 RCP scenarios, as recommended by the IPCC using the simCLIM model. The result obtained shows the median projected sea-level rise values range from 11.86 cm to 49.22cm for RCP 2.6; 11.73 cm to 58.91 cm for RCP 4.5; 11.28 cm to 62.28 cm for RCP 6.0; 11.92 cm to 84.25 cm for RCP 8.0 respectively. Based on the results of the projections obtained in this study, coastal planning is advisable to provide a means of adaptation for the inhabitants as the consequence of lack of planning could lead to avoidable losses.

Published: March 2021

Abstract
Plant genetic diversity loss particularly of under-utilized species threatens several developmental goals in Africa. Preferred safeguard strategies and techniques have failed in stemming this situation exacerbated by dearth in global information and poor research attention on such species amongst other pitfalls. The study involved an expedition to; generate eco-geographical and related information on 30 under-utilized species; evaluate the prevailing situations for collection exercises in Nigeria, in the attempt to instigate globally relevant researches, conservation and sustainable partnerships. A two-phased systematic field survey (North and South) employing a 50 km regular transect distance, covering the wet and dry seasons, a cumulative distance of 8168 km, 192 communities in 34 states and the Federal Capital Territory (FCT) of Nigeria. Collection diversity was determined with Simpson’s Diversity index (1-D) as well as species abundance. 703 accessions of 30 plants species were collected. 13% of the total species (16% -South; 40% - North) were common to both regions. High diversity (D = 8) was recorded for the collection. The wetter southern states were significantly more diverse (D = 0.7- 0.9) than the north. The north west and some south eastern state recorded lesser diversity and the FCT the least (D = 0). 6 species recorded significant species abundance across the study area. The study area is heavily imparted yet houses a considerable diversity of the species surveyed. It is imperative to pursue integrated strategies to harness the plentiful flora as well as cultural resources resident therein. The species studied can be employed to tackle the challenges of climate change, livelihood, economy, food and nutrition security and farmer/grazers/construction activity unrest.

Authors: Leizou Kaywood Elijah 
Published: March 2021

Abstract
Yenagoa is a non-industrialized city. This work aims to investigate the distribution, content and source of the sixteen United State Environmental Protection Agency (USEPA) priority polycyclic aromatic hydrocarbons (PAHs) in urban soils of the Yenagoa, Bayelsa State, Nigeria. The PAH concentrations in the urban soil samples were performed using GC–MS method. The Swali market axis of the city had the highest concentration (∑PAHs). The burden of low molecular weight (LMW) PAHs follows a decreasing order: Phenanthrene > acenaphthene>cenaphthylene>naphthalene> anthracene>fluorine and while the burden of high molecular weight (HMW) PAHs follows the decreasing order: Pyrene> Dibenzo (a,h) anthracene > indeno [1,2,3-cd] pyrene (InP> Chrysene> Fluoranthene> Benzo(a)anthracene> Benzo(k)fluoranthene> Benzo(b)fluoranthene. PAH fingerprint ratios for determining both petrogenic and pyrogenic (pyrolytic) PAH accumulation was employed. The Ph/An ratio for the soil samples were 2.49, 3.47, 0.613, 1.59, 1.99 and 2.44 respectively. This may be indicative of pyrogenic (pyrolytic) origin. Ind(1,2,3-cd)P and DbahA were high in the soils, this may indicate a major concern for carcinogenic risk and demands an urgent attention from policy makers and the government.

Authors: Gubali H , Abdullah N 
Published: March 2021

Abstract
Farmers tend to use chemical fertilizer to boost their water spinach production. Consumers’ demand for high quality and the chemical-free product should be considered in using less chemical fertilizer. A possible solution is using a safe and eco-friendly bio-organic fertilizer. In general, this study purposes of supporting food security, which can provide food with the best quality and safe to consume by people and not harm the environment. Moreover, this study aims to acknowledge the effectivity of bio-organic fertilizers (Petrobio, Marolis, and Fertismart) toward the plant’s growth and production of water spinach. This study used the factorial plan in RAL, which consists of 2 factors. First, the bio-organic fertilizer that has 3 stages: Petrobio, Marolis, and Fertismar. Second, the use of NPK fertilizer: without NPK, 50% used, and 25% used for each trial should pass three times examination. The result shows that using bio-organic fertilizer can affect the plant’s growth and productions, with the evidence of the plant’s height, number of leaves, and plant’s net-masses. Bio-organic could decrease the application of chemical fertilizer; by contrast, it can’t substitute NPK to boost the water spinach production. The best result was from the fertilized plant using Marolis alongside with NPK.
