3 Types of Rural Land Rangeland Forest land Cropland Parks and Preserves Graze livestock and wildlifeForest landHarvesting woodFishWildlifeCroplandGrow foodParks and PreservesRecreationAesthetic purposesPreserve native plants and animalsWetlands, mountains, deserts, etcLand that is difficult to use for human purposes
5 Why are people dependent on rural land, no matter where they live? Ecosystem services: services that are provided from natural environments that can have a monetary value associated with themWoodFoodWater filtrationShelterClimateFlood control
6 If we rely on rural services then why do we live in urban areas? Green revolutionHigher yields for same area.Less man power neededIndustrializationMovement into cities
7 Positives to Moving to urban areas Better jobsResources in smaller areaTransportationMore jobs
8 Negative impactsUrbanization: Rapid movement into cities which puts stress on infrastructureInfrastructure: all buildings, bridges, roads, schools, medical care, electricity, water etc. that a urban are uses.Urban sprawl- rapid expansion from urban area into the surrounding suburban areaHeat island- increased temperature due to infrastructureSuburban sprawl- further movement into suburban areas.
9 Land Use Management:Land use planning- the advanced determination of how land will be used for homes, business, factories, and recreation.
10 Farmland aka Cropland20% of US land that is used to grow crops and fruit.250 million acres1996 National Farmland Protection ProgramStrives to prevent Urban sprawl from taking over farmland
11 Rangeland28% of U.S. land which is used to support vegetation found in grasslands, forests, deserts, but is not used for farming or timber.Soils tend to be infertileMostly used for grazing animals such as cattle, sheep, goats.Important for the world’s meat supply.
12 Problems on the RangeOvergrazing- allowing more animals to graze on an area than that area is capable of supporting.Tragedy of commons ideaLeads to degradation and soil erosion
13 PUBLIC RANGELANDS IMPROVEMENT ACT OF 1978 Limits heard sizeCreate recovery periods when no herds allowedKill invasive plants and plant nativeIncrease grazing locations via water-hole creation.
14 Forest Land - forest that is planted and managed 28% of land ~1,800cm3 of wood used per person per day in worldUS uses 3.5 x as much as dvping countriesDvping countries use wood as main source of fuel.3 types of forestVirgin forest- forest that has never been cutNative forest- forest that is planted and managedTree Farms- trees that are planted in rows and harvested like crops
