Study Notes

Urbanization Problems

Air and water quality decline due to pollution from industries and vehicles.
Waste management challenges arise from increased waste generation in urban areas.
Housing shortages lead to vertical expansion and growth of slums.
Competition for jobs and resources intensifies, leading to increased unemployment and inequality.
Urban crime rates tend to be higher due to increased population density and social disparities.
The cost of living rises due to demand for limited resources, making it harder for lower-income residents.

Urbanization Benefits

Economic growth fueled by increased employment opportunities and business activity.
Improved transportation infrastructure, leading to better connectivity and accessibility.
Higher average wages in cities compared to rural areas.
Access to better education and healthcare services in urban centers.
Growth of tourism due to attractions and cultural experiences.

Trends in Urbanization

The global urban population has significantly increased, surpassing the rural population for the first time in history.
By 2050, the world is projected to be two-thirds urban and one-third rural, reversing the rural-urban population distribution of the mid-twentieth century.

Urban Biodiversity

Refers to the variety of living organisms found in cities and their ecological systems.
Highly influenced by human activities, leading to changes in species composition and distribution.

Why Urban Biodiversity Matters?

Conserving urban biodiversity benefits both wildlife and people.
Offers benefits like flood risk reduction, pest control, pollination, mental health improvement, and community building.
Indicators of environmental health, showcasing a healthier environment and less pollution.

Impact of Urbanization on Biodiversity

Leads to biotic homogenization, favoring generalist species over specialists.
Mobility and specialization influence how species adapt to urban environments.

Benefits of Biodiversity

Improved air quality through natural filtration processes.
Climate regulation through carbon sequestration and shade provision.
Ecological resilience through diverse ecosystems for better adaptation to change.
Pollination of urban flora, contributing to food production and ecosystem services.

Types of Urban Biodiversity

Green Spaces: Parks, gardens, forests, and other areas with vegetation.
Blue Spaces: Bodies of water like rivers, lakes, and ponds.

Benefits of Urban Green Spaces

Environmental benefits: Heat reduction, greenhouse gas offsetting, and storm water attenuation.
Health benefits: Physical activity spaces, social interaction opportunities, and psychological restoration.

Benefits of Urban Blue Spaces

Improve physical and mental health, offering calming and restorative experiences.
Provide opportunities for recreation, leisure, and connection with nature.

Main Differences Between Ecology and Ecosystem

Ecology: Study of interactions between organisms and their environment.
Ecosystem: Community of interacting living organisms and their physical environment.
