All Flashcards
Cause: Increased impervious surfaces in urban areas. Effect?
Reduced percolation and increased runoff, leading to flooding.
Cause: Burning fossil fuels in cities. Effect?
Increased CO2 emissions and contribution to climate change.
Cause: Deforestation for urban development. Effect?
Reduced carbon sequestration and habitat loss.
Cause: Increased waste generation in urban areas. Effect?
Waste disposal issues and potential pollution of land and water.
Cause: Urban sprawl into agricultural areas. Effect?
Loss of agricultural land and reduced local food production.
Cause: Increased runoff in urban areas. Effect?
Increased surface water pollution and reduced groundwater recharge.
What is Urbanization?
Increase in the number of people living in cities and towns; a population shift from rural to urban areas.
What is Urban Sprawl?
Urban growth that spreads into rural areas with little to no planning.
Define Sustainable Development.
Meeting current needs without compromising the ability of future generations to meet their own needs.
How does urbanization affect the water cycle?
Reduces percolation, increases runoff, less groundwater recharge.
How does urbanization affect the nitrogen cycle?
Alters plant growth, increases nitrogen runoff.
How does urbanization affect the carbon cycle?
Increases CO2 emissions, deforestation reduces CO2 capture.
What are some environmental stresses caused by urban sprawl?
Water pollution, reduced water supply, habitat loss, waste disposal issues.
What are some benefits of urbanization?
Better education, healthcare, employment, economic growth.
What are some negative impacts of urbanization?
Congestion, pollution, loss of natural areas, biodiversity loss.
Why is sustainable urban development important?
To minimize environmental impact and meet the needs of current and future generations.
