Natural vs Impervious
These surfaces have a higher percentage of runoff.
What are impervious Surfaces?
The most inefficient method of irrigation
What is flood irrigation?
Runoff travels along this path.
What is down the watershed?
Ranchers can do this to limit overgrazing.
What is limit the density of livestock on grazing land?
This effect of overgrazes inhibits inflitration.
What is compaction?
These surfaces have a higher percentage of infiltration.
What are natural surfaces?
This is the main cause of salinization.
What is excessive irrigation?
This phenomenon explains why organisms at the highest trophic level die first from pollutants, often carried by runoff.
What is bioaccumulation?
Homes that store their waste in these systems must have it checked every few years to ensure no runoff.
What are septic systems?
Livestock waste can lead to this in bodies of water.
What is eutrophication?
These surfaces have a higher percentage of evapotranspiration.
What are natural surfaces?
It is easier to do this rather than remedy salinization?
What is prevent?
This is the most prevalent source of agricultural pollution.
What is soil erosion?
Cities can include more of this in their planning to decrease runoff.
What is vegetation?
Runoff increases because of this phenomenon where there are too many cows and they eat too much vegetation.
What is overgrazing?
This significantly inhibits soil erosion in natural surfaces.
What is vegetation?
Waterlogging kills plants because their roots are deprived of this.
What is oxygen?
Aside from farms, these are a significant polluter of pesticides.
What are homeowners?
What is use more porous concrete for driveways?
This is why humans are more susceptible to diseases from CAFOs.
What is runoff of pathogens from cow waste?
This phenomenon allows for more pollution to come from areas with impervious surfaces.
What is places with a high concentration of impervious surfaces are usually located in cities, and cities have significantly more pollution than other areas?
This method of irrigation is perhaps the most effective, yet most expensive.
What is drip irrigation?
Eutrophication is connected to runoff because of this.
What is nutrients from fertilizers running off and feeding algal blooms, which then leads to hypoxia?
This is an efficient method to limit the use of potentially harmful pesticides that could runoff and wreak havoc on the local ecosystem.
What is integrated pest management (IPM) ?
Overgrazing can lead to wider rivers because of this.
What is destruction of vegetation along river banks?
