Humans Use 83 Percent of Earth's Surface 719
belloc writes "CNN is reporting on a Wildlife Conservation Society report that states that humans take up 83 percent of the Earth's land surface to live on, farm, mine or fish. The article rerers to a WCS human footprint map, but the WCS site seems to have been CNN'd. Funny: I just got back from a little road trip across the southwest, and from all the nothing you see out there, you would think that 83% is a bit high.

About the Data
Last updated 6 September 2002
General issues:
The maps of the human footprint and of the last of the wild should not be read too literally. Although there is no doubt that the human footprint and last of the wild express an important perspective on the world, it is also true that, in its details, these maps contain inaccuracies (acknowledged below) and are mapped at a scale coarser than most conservation efforts
These maps are based on geographic proxies for drivers of human impact: human population density, land cover and land use mapping, lights regularly visible from a satellite at night, locations of roads, rivers and coasts, settlement patterns, etc. However drivers are not inevitably impacts. One of the roles of conservation is to find ways for human beings to lessen their impacts while still making their living.
The input datasets used to map the human footprint are enormously expensive to maintain and update, as a result they tend to lag behind the patterns they depict. All the datasets used here were released in the 1990s, however some are based on much older datasets or datasets which are incomplete. In all cases they do not depict the current 2002 extent of roads, settlement or population density. This problem leads to underestimates of the amount of human influence.
The methods used to produce the input datasets themselves have problems. For example, there are known problems mapping grazing lands, particularly in arid regions. Settlements data and roads are not identified by the type of settlement or road. The lights data sometimes over-estimates the "lit" area for over-bright pixels. The population dataset relies on population estimates made in different countries using different census techniques, which sometimes results in marked changes across national boundaries. These problems probably lead in most instances to underestimates of human influence, but may result in overestimates in some cases.
Our interpretations of the amount of human influence based on the input factors relies on simplified scales from 0 to 10 which do not vary by region, biological or cultural context. The understanding of the human influence on nature is in its infancy, and despite 100 years of ecological science, not known very well; however we do know enough to be concerned. We tried to be conservative and common sensical in our determinations of human influence from the various input factors, using advice from the scientific literature and our colleagues.
We probably overestimate the direct effect of roads in some cases. Direct influence from roads in terms of pollution, soil compaction, modification of stream courses and waterways, introduction of new species, and road kill is known to vary from a few meters to up to several hundred meters from roads. The roads dataset we used maps roads only to an accuracy of 2 km, so we treated all of this 2 km region as influenced by roads. We also treat human access from roads as up to 15 km from roads of all types, though this may be less in some countries and more in others.
The level of access from rivers is probably also incorrectly estimated in some instances. We defined access along all major rivers, where a major river was defined as one depicted as one or more polygons in the input database and connected continuously to the sea. However access along all rivers is probably more likely, since any river large enough to be mapped is probably large enough to support a canoe or other boat. But our rivers dataset does not include the effects of waterfalls or dams, which can impede access up rivers.
The human footprint and the last of the wild do not directly take into account war and conflict between groups of human beings, though these effects may dramatically influence the outcomes of human influence on wildlife and wild places. In some cases, for example, conflicts lead to increases in the levels of hunting because of increased access to weapons, even long after the war has ended (for example, in Cambodia.) In other cases, conflicts result in lower human population densities and less investment in infrastructure (for example, in Angola) with the result that areas become wilder.
The human footprint and the last of the wild are not the complete story of conservation. In fact they do not directly consider conservation targets (animals, plants, air, soil or water processes) at all. Conservation planning requires understanding what is important to conserve in a given area (the conservation targets), how those conservation targets respond to human influence, and the type and degree of that human influence. The last of the wild is not a complete prescription for nature conservation. Even if we saved all of the last-of-the-wild areas, our task would be incomplete.
Specific points:
Brazil - a tile of the roads dataset is missing in central Brazil along the eastern edge of the Amazon rainforest in the region of the Chapadas das Mangabieras.
Democratic Republic of Congo - another tile of roads is missing in the central part of the country.
New Guinea - in Irian Jaya human influence from the Taritatu River is over estimated, because although it is a large river connected to the sea, there is little human movement up the river into the Foja Mountains Reserve, a relatively pristine area that appears heavily influenced on the human footprint map. In general the human footprint map seems to over-estimate influence in many parts of New Guinea and should be used with caution.
Tundra and boreal forest biomes - Access during winter months is not restricted to roads or rivers, but can occur wherever the snow is packed enough to support a motor vehicle.

Why? Because ranchers graze there. If cows aren't there currently, it means either/both: 1) the parcel is overgrazed and can no longer support animals; or 2) the rancher has moved his herd to another field with fresh grass. Remember, the point of the report being discussed is not about habitation but about use. There don't have to be cowboys ropin' steers within sight of the road to make it a working ranch.

This is a fine forum to talk about tech, but a tough audience to talk about the non-artificial world. I suppose that too many are born, live, and die in cities where a lawn qualifies as "nature". Use /. for its strengths, and don't sweat the rest.

This is as silly as saying that 22% of the earth is covered by clouds. You mean right now? What about yesterday? How thick are the clouds? How accuratly are we measuring the irregularities in their shapes?

To tell you the truth, i don't see *ANY* land that ISN'T marked by humans.
Where do you fly?
During my private pilot training, I flew with my instructor for Bluefield West Virginia to Dublin Virginia at night and in visual flight conditions. After we got out of Bluefield, there was NOTHING for 27NM. Well, there was one solitary porch light, and we saw some heat lighting in Tennessee (you can see that far at 7500'), but that was it.
If you want open land, go to Alaska. Sure it's cold - but there ain't too many people up there. I almost moved there.. I even got a job offer, but decided to stay with my friends and family down here in Virginia.
Re:Incorrect summary (Score:2, Insightful)
To be more accurate, we are one of the only species that has the ability to make lasting impacts on our environment before we get a clue on what we're doing. Case in point: we domesticated the apple tree, and over time narrowed thousands of varieties (a fraction of which surviving only in dedicated labs and preserves) down to a handful. Today, the apple requires the most amount of pesticides, because they no longer have the genetic diversity to evolve along with their parasites. Oops.
The pesticides we use, in turn, poison other things we didn't intend to, like our own water supply. Oops.
Note that I'm not talking about some metaphorical Mother Earth, just that human actions so frequently backfire even on ourselves that your top-of-the-food-chain arrogance is really quite unwarranted. It's even worse if you do accept a moral responsibility of stewardship for our planet corresponding to our power.

Correction- there are lots of studies that theorize that we may be destroying our environment. There are also lots of studies that disagree with those theories. In fact, the NOAA link that you posted says that all of the climate change that has been observed could just be caused by variations in the sun's intensity or the earth's orbit. Some people theorize that the build-up of "greenhouse gases" like CO2 is not causing a climate change, but rather a symptom of it (like this article [osu.edu] for example).
Either way, none of those links that you gave make the jump that you made that our entire eco system is going to irreversibly collapse.
Your claims that the earth is overpopulated are also crap. Right now, you could fit everybody on the earth into Texas with about the same population density as Paris, France (look here [ncpa.org]). And the global population growth rate has been decreasing for the past 30 years.
Nobody is calling for the blatant misuse of our environment, but I think the earth is a lot more robust that you give it credit for, and I think that humans are not as influential to the environment as you seem to think.
