• • Bell ringer (verbal): What different things do we use land for?

  • 14-1 notes - how we use land

    • Land use and land cover

      • Land cover is what's on the land, and affects how we use land (trees vs. parking lot)

      • urban - land mainly covered with buildings and roads, many people clustered together

      • rural - land with lots of open spaces, relatively few people

    • Land use

• • • Where we live

      • Until around 1850, most lived in rural areas

      • After the industrial revolution, population shifted to urban areas (cities)

    • The urban-rural connection

      • Everyone depends on resources from rural areas

      • ecosystem services - resources provided by natural and artificial ecosystems (clean water and air, flood and climate regulation)

      • Each person in most developed countries use 20 acres worth of resources. People in less developed countries use an average of 6 acres worth of resources. The average person in the US uses about 30 acres worth of resources.
