Considerable numbers of outdoor workers worldwide are exposed to solar radiation and this exposure induces various adverse health effects on the workers. This study was conducted to determine the effect of solar radiation on human response during block laying in Ogun State, Nigeria. Two hundred and four masons performing block laying in outdoor environment were investigated between January and December. The meteorological parameters were measured and recorded around the mason which in...
ABSTRACT Gas flaring is one of the associated activities of the oils and gas industry, which poses negative impacts on the environment such as climate change, impact on health and economic loss. The Nigerian government has tried putting a stop to gas flaring but to no avail, there is a continuous flaring of gas by oil companies operating in the Niger delta. This research answers the question of the volume gas flared by Oil Company and also the increased or decreased volume flared. The re...
One thing leads to the other. Deforestation leads to climate change, which leads to ecosystem losses, which negatively impacts our livelihoods – it’s a vicious cycle” – this is the famous quote by the Supermodel and United Nations Goodwill Ambassador, Gisele Bundchen. Nowadays, one of the most topical issues that have received extensive attention in Environmental and Development Economics centers on what Bundchen was talking about.

ABSTRACT The pattern and profile of energy use prevailing today raises important questions about linkages between energy and the economy, social issues, security and above all, environmental protection. Rwanda has a number of potential energy resources from biomass, hydro, solar, petroleum, methane gas, wind and geothermal. However, the major issue in this regard is the technological exploitation and scientific data on this potential. The widespread and inefficient use of traditional biomas...
ABSTRACT This study was undertaken to determine the quality of water by determining the e physicochemical parameters, chemical parameters and bacteriological properties of piped water, and boreholes water in Dar es Salaam city, as well as determination of the seasonal variation of raw water quality. Piped water samples were purposively collected at the point of treatment to the point of use. However all the operational boreholes water samples were sampled. Chlorine, conductivity, temperatur...

ABSTRACT In modern agriculture, inorganic fertilizers are commonly being used to supplement soil nutrients, to promote plant growth, to increase crop productivity and also improve food quality. Fertilizer adoption in Uganda in small holder agriculture is among the lowest in comparison with other Sub-Sahara African countries. This study was carried out to investigate the adoption of inorganic fertilizers for crop production in Soroti district by identifying the common types of inorganic fert...
ABSTRAa Biomass briquettes, made by compacting biomass waste, have a wide variety of uses from househoid to institutional and industrial fuels but have not been fully exploited as a fuel source in the past. The overall objective of this study was to generate information on organic biomass fuel briquettes that can be utilized as an alternative fuel to unsustainable wood charcoal in order to conserve Uganda’s forest resources. Questionnaires, face-to-face Interviews and experiñients were uà...
Public transport is crucial for the growth of any economy and trade, both of which are highly dependent on the conveyance of people and goods. However, there is, in many cities of developing countries, a major challenge of adjusting the existing system of mobility to the evolving transportation needs of the people. The situation in the Accra Metropolitan area provides a template of the circumstance in most of these city-regions. Against this backdrop, the study investigated the use of public ...
ABSTRACT There is insufficient freshwater in the world for everyone’s essential personal and domestic needs (Johns, 1998). However, lack of distribution nei:works and working systems to extract groundwater or harvest rainwater; exclusion from these services or facilities; inequitable allocation of water resources; and pollution, limit people’s access to sufficient clean water. Large numbers of households in cities around the developing world do not have access to safe drinking water. This...
ABSTRACT The study assessed the characteristics of wastewater of Nyabugogo stream highlighting on their sources and the nature of contaminants they constitute as Chemical and Physio-chemical. It was anticipated that the water in the stream had high levels of both solid and liquid contaminants originating from domestic and industrial activities and wastewater discharges into the stream. The objectives of the study were to assess the nature of contaminants in the wastewater discharged into Nya...
