- Description: The construction industry is vital to the existence of other industrial sector and provides the environment under which other sectors operate. It is the largest industry and contributes about 10% of the gross national product (GNP) in industrial-ized countries. It also plays a major role in development and reaching the goals of society. The current study aims to establish the factors required in the manage-ment of good site management on construction sites in Swaziland. The study is conducted with reference to existing theoretical literature, published and un-published research. The study is mainly a literature review/survey on site man-agement practices on construction sites. Findings emanating from the study reveal that realistic studies have identified a number of problems on site management practices such as management and administration problems, technical problems and communication problems. It also indicates that site management involves a mixture of activities which turn basic sources to a finished product. The study presents a strong background on site management practices on construction sites in the Swaziland construction industry.

- Description: The purpose of the paper is to investigate safety hazard identification in the con-struction industry towards the improvement of employee’s health and safety (H&S). Unidentified hazards in the construction industry are likely to present the most unavoidable risks. Therefore, hazard identification is paramount to con-struction safety management since risk assessment is the practical means by which hazardous events are managed. The study is mainly literature review with reference to existing theoretical literature, published and unpublished research. The paper presents an overview of hazards and accident causation. The findings from the study have shown that falls at construction sites are the leading cause of death and most of these deaths were attributed to falls from roofs, scaffolds, and ladders. Construction accidents lead to delay in project completion, increase the expenses and ruin the reputation and reliability of constructors. The following were identified as some of the barriers to H&S improvement: lack of information sharing across projects, full-time safety department, subjective nature of hazard identification and risk assessment. The study explores safety hazard identifica-tion in the construction industry towards the improvement of employee’s H&S. The study presents a strong background on hazard identification in the construc-tion safety management.

Evaluating land cover change and its impact on hydrological regime in Upper Shire River Catchment, Malawi

- Description: A study was conducted to investigate hydrological impacts of land cover changes in the degradation of the hydrological on flow regimes of the Upper Shire river, Malawi. Remote sensing techniques were used to inventory temporal changes of land cover changes in the catchment. Hydrological data were analyzed to reveal the alterations ecosystems, and water resources for an informed decision on proper catchment planning and management and trends for two periods; 1989 and 2002. The study revealed significant changes in magnitude and direction that have occurred in the catchment between 1989 and 2002, mainly in areas of human habitation. Trends in land cover change in the Upper Shire river catchment depict land cover transition from woodlands to mostly cultivated/ grazing and built-up areas. The land cover mapping showed that 23% of the land was covered by agricultural land in 1989. Subsistence agricultural area has increased by 18%, occupying 41% of the study area in 2002. The effects of the derived land cover changes on river flow in the Upper Shire river were investigated using the semi distributed soil and water assessment tool (SWAT) model. River flows were found to be highly variable and sensitive to land cover changes. Simulation results show that 2002 land cover data produces higher flow peaks and faster travel times compared to the 1989 land cover data. The changes detected indicate the effects of land use pressure in the catchment. The study highlights the importance of considering effects of land use and land cover changes on ecosystems, and water resources for an informed decision on proper catchment planning and management.
