Baseline information on the socio-economic environment is a critical component of Environmental Impact Assessment (EIA) for environmental health. It refers to the collection, analysis, and documentation of existing social, economic, and demographic conditions in a study area before the implementation of a proposed project or development activity. This information serves as a reference point against which potential impacts of the project can be assessed, monitored, and mitigated. The socio-economic baseline provides insights into the quality of life, livelihoods, health status, income distribution, employment patterns, cultural practices, community infrastructure, and social services available to the population residing in or near the project area. It encompasses both quantitative data, such as population density, literacy rate, income levels, and employment statistics, as well as qualitative aspects, including social cohesion, community perceptions, traditional practices, and vulnerability to environmental risks. The first step in establishing baseline socio-economic information involves identifying the study area and defining its boundaries, taking into account administrative, geographic, and environmental considerations. Data collection methods typically include household surveys, interviews with key informants, focus group discussions, review of secondary sources like census reports, government publications, and statistical databases. GIS mapping and demographic profiling are often employed to visualize spatial distribution of population, resources, and social infrastructure. Key indicators generally assessed include population size, age and gender composition, education levels, occupational patterns, income distribution, housing quality, health status, access to water and sanitation, energy sources, transportation networks, and community services such as schools, clinics, and recreational facilities. Analyzing baseline socio-economic data helps to identify vulnerable groups and populations that may be disproportionately affected by environmental changes or development interventions. Vulnerable groups may include low-income households, women, children, elderly individuals, marginalized communities, and those dependent on natural resources for their livelihoods. Understanding these dynamics enables project planners to develop mitigation measures that minimize negative impacts and promote social equity. Baseline data also provide an essential framework for projecting potential impacts on employment, income generation, local economy, public health, education, and community well-being. It allows decision-makers to weigh benefits and risks associated with the proposed project in a comprehensive manner. The impacts of socio-economic conditions on environmental health are multifaceted. Changes in employment and income levels can influence access to nutritious food, healthcare, and safe housing, thereby
