}, The Norwegian capital Oslo is the only urban area of the state. 04:56 The answer to the question “How long are coastlines?”  is: undefined! Norway: D = 1.52 Questions: The four countries listed above are shown below, rotated to make them less easy to recognize. Save my name, email, and website in this browser for the next time I comment. So my coastline should be drawn again by taking into account the new details that come up. The other part is the methodology used to measure coastlines. Let’s make the exercise again but draw the line more precisely: Now we get 4 167.6 km … still far way from the 25 148 km. Norway attempted to stay neutral in World War II (like all other Nordic Countries) and remained so until the 9th of April 1940, when Germany invaded both Denmark and Norway as part of Operation Weserübung. This results from the fractal-like properties of coastlines.The first recorded observation of this phenomenon was by Lewis Fry Richardson and it was expanded by Benoit Mandelbrot.. More concretely, the length of the coastline depends on the method used to measure it. This results from the fractal curve-like properties of coastlines, i.e., the fact that a coastline typically has a fractal dimension (which in fact makes the notion of length inapplicable). The rst recorded observation of this phenomenon was by Lewis Fry Richardson and it was expanded by Benoit Mandelbrot. The Coastline Paradox Explained. So what would be determined as the base line for legal bounderies mesurment? Nearly 300 million people inhabit these deltas. The first recorded observation of this phenomenon was by Lewis Fry Richardson and it was expanded upon by Benoit Mandelbrot. [1] [2] It was first observed by Lewis Fry Richardson.More concretely, the length of the coastline depends on the method used to measure it. This considers only the mainland coastline and excludes Svalbard. For instance, whatever the zoom level you’re using, you should see little to no difference with the Belgian coast (almost a straight line – SI close to 1). In addition, another 4,700 km have become artificially stabilised (1). How Long Is the Coast of Britain? })(120000); The deltas in this study represent all major climate zones, levels of population density, and degrees of economic development. These production levels are driven by a strong and growing demand for farmed fish, and has a stated political goal of increased growth by a factor of 5 by 2050 in Norway alone. The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. All European coastal states are to some extent affected by coastal erosion. The country has a total coastline of around 19,924 km, and 23 states of the country have a coastline to call their own. Coastline Market is an online platform connecting harvesters with retailers. display: none !important; In fact, the coastline paradox has never been considered as a significant source of legal problems. A Map and Street View experiment visualising the actual and predicted global sea level rise caused by the climate crisis. You cannot go further west in Norway. The aquaculture industry in Norway currently represents 60% (US$ 5.4 billion) of Norwegian seafood exports. Please reload CAPTCHA. No-one knows how long Norway's coastline is! But this is only a part of the story …. Just a little precision: The “B” in the name “Benoit B. Mandelbrot”, stands for “Benoit B. Mandelbrot”, which “B” stands for “Benoit B. Mandelbrot”, which “B” stands for “Benoit B. Mandelbrot”, … funny isn’t it . What if I had measured the coastline by zooming even more in until I come to the level of atoms ? The coastline of Norway is formed along the Skagerrak, North Sea, Norwegian Sea, and Barents Sea. Coastal erosion results in three different types of impacts (or risks): Coastal erosion is influenced by several human factors, including (1): From an assessment of contemporary effective sea-level rise (ESLR) for a sample of 40 deltas distributed worldwide it was concluded that direct anthropogenic effects determine ESLR in the majority of deltas studied, with a relatively less important role for eustatic sea-level rise. This is called the coastline paradox and here we get it! The spectacular Norwegian coastline draws visitors in the millions every year. According to this study, serious challenges to human occupancy of deltaic regions worldwide are conveyed by other factors than the climate change–sea-level rise (4). Coastline Paradox. Most of the impact zones (15,100 km) are actively retreating, some of them in spite of coastal protection works (2,900 km). And neither the CIA World Factbook nor The World Resources Institute tells what they use as unit of measure. That's because it's impossible to accurately measure coastline. What is known is that the CIA World FactBook numbers and scales used vary for all countries, thus making comparing the numbers worthless. by Daniel Demonceau. World Resources Institute measures the coastlines of the countries INCLUDING overseas islands The World Resources Institute measures the coastlines of the countries INCLUDING overseas islands. Timber has always been a major export of the Norwegian economy and trade ships from the Low Countries have become an increasingly common sight along the Norwegian coastline. I would have had an even bigger number as long as I zoom on (but I have not my entire day ahead of me for digitizing the coastlines at each zoom level). Undermining of artificial sea defences as a result of chronic sediment shortage, Salman et al. Approximately 20% of the deltas show accelerated subsidence, while only 12% show eustatic sea-level rise as the predominant effect. Wikipedia® is een geregistreerd handelsmerk van de Wikimedia Foundation, Inc., een organisatie zonder winstoogmerk. Collectively, the sampled deltas serve as the endpoint for river basins draining 30% of the Earth's landmass, and 42% of global terrestrial runoff. We are drawing our line a scale which is far too small. Basically the problem is defining what is meant by a coastline, which must, inherently, be arbitrary, and could produce a wildly different result depending on what standard you pick. Use the relative roughness of each coastline to identify the country, and enter its name in the box below the image: [ ] [ ] [ ] [ ] The CIA, for example, lists Norway as the second longest coastline in the world after Canada. Coastline Paradox: The coastline paradox says that the coastline of a piece of land does not have a finite length. Resize; Like. If we examine the "official" numbers listed here, Norway has 20X more coastline than land boundaries, while Chile has approximately the same coastline as land boundaries -- … Canada and Norway (the top 2 in that list) have a lot of "crinkly" bits -fjords, bays, inlets etc. If the coastline of Britain is measured using units 100 km long, the total length of the coastline is approximately 2,800 km long whereas if … The key here is the scale! June 2020 | By Timo Aho, Pekka Niittyvirta, in collaboration with Google Arts and Culture . Search Cart. The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. Here a quick example of a fractal (the Koch Snowflake): Benoit B. Mandelbrot worked on this paradox and released in 1967 a paper called “How Long Is the Coast of Britain? By changing the zoom level, I … Destruction of natural sea defences (usually a dune system) as a result of storm events, which may result in flooding of the hinterland. The first external link on the page seems to be the source of the article's problems. The United States of America is one of the largest countries of the world, and is composed of 50 states, fiver major territories, and several minor territories. Norway is located in northern Europe on the Scandinavian peninsular. It's not exactly a paradox- it's sometimes called the coastline problem, which is a better name, I think. This results from the fractal-like properties of coastlines. I.e for teritorial water or international bounderies in the sea. Please click here if you are looking for the full references for Norway. Extrapolating contemporary rates of ESLR through 2050 reveals that 8.7 million people and 28,000 km2 of deltaic area in the sample set of deltas could suffer from enhanced inundation and increased coastal erosion (4). This is one difference. This article is the first to address the legal implications of the coastline paradox. To say the relatively tiny country of New Zealand has over 3/4’s the coastal area of the United States is laughable. DIY maps, geoapps, discoveries … and magic in geography, Posted on October 5, 2014October 24, 2014 by Daniel Demonceau For my two tries to determine the length of the coastline, the first, less precise, indicated 3 049.1 km while “the little more precise” was 4 167.6 km. A Greenpeace protester opposing the Statoil Songa Enabler oil rig north of the Norwegian coast. 418 Views. Severe coastal erosion will be a growing problem as rising sea levels and a reduction in sea ice allow higher waves and storm surges to reach the shore. The landscape of the Fjord Coast has been shaped through thousands of years. However if you sort the list by "World Resources Institute" instead you'll see very different numbers, with Norway dropping to 7. Ok, I was not so precise as I draw the line. Time limit is exhausted. So, for measuring the most precisely a coastline, do I have to take into account all the little islands, the cracks, the fjords, etc. notice.style.display = "block"; 03:14 Greenpeace holds a historic performance with pianist Ludovico Einaudi on the Arctic Ocean (English) 571 Views. Unlike the Hanseatic traders who have dominated our economy for centuries the Dutch are content to trade without meddling in local businesses or breaking the laws of the land. Along the coast there are many fjords, islands, and bays, resulting in a low-resolution coastline of over 25,000 kilometers (16,000 mi). In a previous blog, I wrote about 9 upsides of my first year in Norway.While it’s been a great experience, Norway isn’t all sunshine and roses. Time limit is exhausted. The coastline paradox is in fact a fractal problem in which the total length becomes more and more larger as much details becomes clear as we zoom in. Much more details and an enormous more work for us if we want to measure the coastline! .hide-if-no-js { Along some arctic coastlines, thawing permafrost weakens coastal lands, adding to their vulnerability (3). Lewis Fry Richardson was the first recorded observer of this paradox. It is dominated by the Scandinavian mountains, which separates Norway from its neighboring country Sweden. This was the beginning of the coastline paradox. 0 items. The World Resources Institute uses the SAME scale and methodology for measuring all countries coastlines, making for a MUCH more accurate comparison. That’s correct! The risk of coastal flooding due to the undermining of coastal dunes and sea defences potentially affects several thousands of square kilometres and millions of people. It's a problem known as the coastline paradox. The Coastline Paradox Explained - Duration: ... Fjord Norway Recommended for you. Featured. Norway does have plains and forested areas, mostly to the southeast and the northernmost part. In addition, another 4,700 km have become artificially stabilised (1). The CIA World FactBook indicates 25 148 km. five The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. (2004). Travel off the beaten track to the Fjord Coast and get a taste of authentic coastal life. Living in Norway is fantastic in so many ways, but it's important to understand the whole picture. According to the CIA World FactBook, the ten countries with the longest coastline are the following (when we take into account Greenland and Antarctica of course): But, if we base our analysis on the data coming from the World Resources Institute, we get the following list: This list IS VERY different from the other list. Interesting subject for a thesis . (2002), in: Salman et al. The length of the coast for the countries of the world For the contemporary baseline, ESLR estimates range from 0.5 to 12.5 mm per year (4). Please reload CAPTCHA. var notice = document.getElementById("hctpc_time_limit_notice_76"); Interesting read. The more I zoom in, the more precise I can be. Because of the fractal nature of a coastline, you can only define its length by using units of a specific length. The coastline paradox, the idea that the perimeter of a land mass is infinite, appears to arise from certain assumptions in the article and incomplete data. The country shares its coastline with the Atlantic Ocean on the east, the Pacific Ocean on the west, the Arctic Ocean to the north of Alaska, and the Gulf of Mexico towards the southwest.
