Other lands are any lands not arable or under permanent crops; this includes permanent meadows and pastures, forests and woodlands, built-on areas, roads, barren land, etc. Land covers 196.9 million square miles of the planet, which is broken up into 196 countries that are home to 7.125 billion people. Seriously? Urban land area where elevation is below 5 meters (% of total land area) Land area (sq. What are the differences between a crater and a caldera? Only 3.74% of cells were No Data and filled via human population density on a country-by-country basis. If we do or don’t do it, someone will laugh, Your email address will not be published. Philosophy of Everyday Life: What percentage of the world’s land is populated by humans? km) Urban land area where elevation is below 5 meters (sq. Seto, Fragkias, Güneralp, and Reilly (2011). This is just 1/4400 the total mass of the Earth, which means that while the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass. Let's do the math again, but this time for the entire planet. The zealots included land which is being farmed and forested, but this land is not subject to any kind of contamination. I kept in my mind this. Both cloud cover percentages are listed in the EarthExplorer metadata, as well as in the Landsat Collection 1 Level-1 metadata (MTL.txt) file. In all regions, urban land expanded either faster or equivalent to population growth rates, suggesting our societies are also becoming more expansive. A Meta-Analysis of Global Urban Land Expansion. 40 billion people would also raise the CO2 emission greatly causing inccreased climate change, which is the cause of stronger hurricanes, animal and plant population decrease and poor air quality for everyone, shortening the life span of humans. By using such imaging satellites as Landsat 5, Landsat 7 and Terra, scientists have the ability to observe large tracts of the Earth's surface in a fraction of the time needed to complete aerial or ground surveys. Land cover maps represent spatial information on different types (classes) of physical coverage of the Earth's surface, e.g. Which biome is the most stable? Understanding the land cover of Earth aids policy makers involved in natural resource management. Scientists calculate that the total mass of the oceans on Earth is 1.35 x 10 18 metric tonnes, which is 1/4400 the total mass of the Earth. 97 percent is salt water and only 3 percent is fresh water. Deserts cover 33 percent of the land area of the earth. Online tool for visualization and analysis. 2. It is interesting to note that of Earth's freshwater sources, about 69% is in icecaps and glaciers (NOAA). The satellite image was classified based on land-use type using ERDAS software, and the land utilization map was manually digitized and grouped into land-use type using Map Info software. the percentage that covers the earth's surface that is land is 30% What covers 30 percent of earth? Brazil . The meta-analysis found that the largest rates of increase in urban landcover were seen in India, China and Africa, while North America experienced the largest total change since 1970. This is down from the pre-industrial area of 5.9 billion hectares. Heat and air travel process causes rain. Doing some writing research and this is usual :O, We should convert sea water into sweat water and we should make canals for providing water in all deserts of the world and that area where rocky barren land where we put arable sand in this way our earth can support 40 billion people. If you need a larger version the file is attached in the lab instructions. Land covered by water, wetland and bareland accounted for a relatively low proportion of total land cover in most of the EU Member States in 2015. Which of the following is the world’s largest biome by area? Sign up now, Latest answer posted June 04, 2009 at 4:59:20 AM, Latest answer posted January 10, 2009 at 7:55:11 AM, Latest answer posted February 25, 2010 at 3:30:18 AM, Latest answer posted October 15, 2008 at 8:21:41 AM. Land covers 196.9 million square miles of the planet, which is broken up into 196 countries that are home to 7.125 billion people. So this means that out of 1000 units of land, we occupy three. Alps and Himalayas Iceland and Greenland Greenland and Antarctica o oo Canada and South America Here is a portion of the Whitewater Wi topographic map. “90% of Earth is covered by humans”! Because of the recent rapid growth, this means that whoever is alive today makes up 6.5 percent of this extremely high number. Area of land: 148 326 000 km2 (57 268 900 square miles), this are 29% of the total surface of Planet Earth. Which land biome covers the largest percentage of land? In the year 2000, estimates suggest that globally, urban land covered somewhere between 700,000 and 3.5 million km2 – but that’s a pretty big margin of error. Being 3500 square miles in size, it is roughly the size of the state of Connecticut. Ultimately there is no one right answer to this question since there are many ways to interpret it – I tried to present a number of different ways of looking at the same question and provide some kind of answer to each. It is very telling that you would leave the reader with that as an actual conclusion, which essentially defeats any of the numbers you provided prior to your “glass-half-empty”conclusion. So on the one hand, you could say from these results that 10% of Earth is inhabited by humans. Land Cloud Cover, which is also included, is determined by calculating the percentage of clouds over land-only pixels in a scene using a mask that discriminates land from water. Both the satellite image and the map were compared to see the changes of percentage and total area of land cover. Russia, and 5. I don’t think the Manhattan fact is true. Dynamic land cover maps include transitions of land cover classes over time and hence captures land cover changes. There are also other discrepancies within your article, so I’m not sure if you just copy&pasted some of the bits (which would be fine generally) without truly thinking about them. Most Recent Year. Approximately half the forest area is relatively intact, and more than one-third is primary forest (i.e. The entire population of the earth can stand on Manhattan Island with room to spare. We contribute only about 0.3% of the atmospheric CO2, so if we stopped everything tomorrow, it would barely register. forests, grasslands, croplands, lakes, wetlands. NLCD (the National Land Cover Database) is a 30-m Landsat-based land cover database spanning 8 epochs (1992, 2001, 2004, 2006, 2008, 2011, 2013 and 2016).
