Putting People On The Map / Global Urban Land Use Trends and Climate Impacts



Anthropogenic Biomes

– Most biomes have been altered by humans. (wow, human dominated Biomes now cover more Earth surfaces compared to wild.)

Existing Biome systems either ignore human interaction or simply into four groups.

-Human interactions on Biomes is often over simplified, but in order to get a global understanding.

-Using Anthropogenic Biomes get a better data set as it divides into 18 groups as opposed to 4, with 3 wild biomes.

80% of human inhabitants live in Dense settlements or villages.  (interesting calculations on mapping, possible question would be to better understand how the information is being process as it seem major areas are considered to be human impacted but in very remote areas. I wonder if this is due to more complex systems like environmental.)

Table 1. Anthropogenic biome descriptions (p 442) good resource for descriptions of biomes.

By using satellite imagery it is fascinating how you can overlay the geographical locations with the implications of human activity. (land cover vs. land use)

Conventional ecosystem model with added human population density and land use:  Ecosystem processes = f(population density, land use, biota, climate, terrain, geology)

Projections though young in development suggest that increased land use is probable.

Conventional Biome systems are not obsolete, however anthropogenic biomes may be more accurate when accounting for human impact on these systems and projections of global trends.

**Interesting in the conclusion**

Human interaction has now become pervasive on what is consider terrestrial biomes. Most of what is considered “nature” is embedded with  anthropogenic mosaics of land use and cover.


 Global Urban Land Use Trends and Climate Impacts

2050 70% of the worlds population will live in urban areas. (mostly in Asia)

How these areas develop determine infrastructure needs and energy consumption.

Once these systems are in place they are hard to reverse, and can be problematic depending on where areas are developed.  (This is in relation to climate impacts, like coastal areas and such)

Economy systems seem to be most effected in concerns of human land use trends and climate impacts as areas move from agriculture to manufacturing.

vital for understanding Urban footprint and the effects it has on climate.
