      • Sustainability: Practices that meet current needs without compromising future generations.
      • Human Impact: Effects of urbanization, agriculture, and industrialization on the environment.

    • Subfields:

      • Physical Geography: Examines natural processes and physical features of the Earth.
      • Human Geography: Studies how human activities affect and are affected by the environment.

    • Issues Addressed:

      • Climate change and its geographical implications.
      • Habitat destruction and biodiversity loss.
      • Water resource management and pollution.
      • Land use changes and urbanization effects.

    • Tools and Techniques:

      • Remote sensing for data collection (satellite imagery).
      • Field surveys for direct observation and data gathering.
      • Statistical analysis to understand environmental trends.

    • Importance:

      • Informs policy and decision-making for environmental conservation.
      • Aids in understanding and mitigating natural disasters.
      • Guides sustainable development practices.

    Geographical Information Systems (GIS)

    • GIS captures, stores, manipulates, analyzes, manages, and presents geographical data.
    • Key components include hardware (computers and devices), software (mapping and analysis programs), data (satellite imagery and surveys), and people (users and analysts).
    • Functions encompass data visualization through maps and 3D models, spatial analysis for pattern identification, and decision support for urban planning and resource management.
    • Applications of GIS span urban and regional planning, environmental monitoring, transportation logistics, and public health tracking.

    Environmental Geography

    • Focuses on the interactions between humans and the environment, emphasizing spatial relationships and processes.
    • Key concepts include ecosystems (interactions among organisms and their environments), sustainability (meeting current needs sustainably), and human impact (effects of urbanization and industrialization).
    • Subfields consist of physical geography (natural processes) and human geography (effects of human activities).
    • Addresses critical issues like climate change, habitat destruction, water resource management, and urbanization impacts.
    • Tools and techniques involve remote sensing (satellite imagery collection), field surveys (direct data gathering), and statistical analysis to interpret environmental trends.
    • Importance lies in guiding policy and decision-making for conservation, understanding and mitigating natural disasters, and promoting sustainable development practices.
