Economy - Environment economics

This work examines the comparative study of activities of Sawmilling Industry on the Environment of two selected locations within Southern Nigeria, Lagos and Delta States between August 2008 and September 2009. The primary data were collected through oral interview and field experiments. While secondary data were from printed materials. The focus has been to compare the various waste generated, its uses and environmental impact on the two locations. Experiments were conducted in the rainy and dry season for the comparative study. The study has been divided into three main areas: volume of waste generated and various uses, effect of type of chain-saw machine used, and impact of sawmilling activities on the environment of the two locations. A natural logarithm transformation of the data was used for some datasets to satisfy assumption of normality and variance homogeneity, means and standard error were back transformed for presentation, specific treatment pairs were compared using a t-test.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This thesis aims to conduct a comparative study of the activities of the sawmilling industry on the environment in two selected locations within southern Nigeria. The study aims to assess the environmental impact of sawmilling activities, including waste generation, noise pollution, water quality, air quality, and soil quality.

• Environmental impacts of sawmilling activities
• Waste generation and management in the sawmilling industry
• Noise pollution and its impact on the surrounding environment
• Water quality parameters and their implications for sawmilling operations
• Air quality and soil quality analysis in relation to sawmilling activities

Zusammenfassung der Kapitel (Chapter Summaries)

Chapter one introduces the research problem, justifying the study and outlining its objectives. Chapter two provides a comprehensive literature review, exploring the environmental impacts of sawmilling activities, particularly in Nigeria. It delves into the importance of forest resources, wood processing technologies, waste generation, and the various forms of environmental degradation caused by sawmilling operations. It also investigates the history of sawmilling and its evolution. Chapter three describes the materials and methods used in the research. It covers the study area, waste measurements, environmental impact assessment methodologies, including water quality analysis, noise surveys, air quality assessments, and soil sampling techniques. Chapter four presents the results and discussions of the study, focusing on log parameters and waste generation, noise quality, water conditions, air quality, and soil quality. The analysis explores the various types of waste generated, the impact of noise on the surrounding environment, the effects of sawmilling activities on water quality, air quality, and soil quality.
