Exploration of Asia During the Early Middle Agesgeographical knowledge in Europe regressed though it is a popular misconception that they thought the world was flatand the simple T and O map became the standard depiction of the world. The trips of Venetian explorer Marco Polo throughout Mongol Empire in the 13th century, the Christian Crusades of the 12th and 13th centuries, and the Portuguese and Spanish voyages of exploration during the 15th and 16th centuries opened up new horizons and stimulated geographic writings. The Mongols also had wide-ranging knowledge of the geography of Europe and Asia, based in their governance and ruling of much of this area and used this information for the undertaking of large military expeditions.
History[ edit ] Spatial variations in food production and consumption practices have been noted for thousands of years.
In fact, Plato commented on the destructive nature of agriculture when he referred to the soil erosion from the mountainsides surrounding Athens, stating "[In previous years] Athens yielded far more abundant produce.
In comparison of what then was, there are remaining only the bones of the wasted body; all the richer and softer parts of the soil having fallen away, and the mere skeleton of the land being left".
Societies beyond those of ancient Greece have struggled under the pressure to feed expanding populations. The people of Easter Islandthe Maya of Central America and most recently the inhabitants of Montana have been experiencing similar difficulties in production due to several interconnecting factors related to land and resource management.
These events have been extensively studied by geographers and other interested parties the study of food has not been confined to a single discipline, and has received attention from a huge range of diverse sources.
Modern geographers initially focused on food as an economic activity, especially in terms of agricultural geography. It was not until recently that geographers have turned their attention to food in a wider sense: Some of the earliest numerical data about food production come from bureaucratic sources linked to the ancient civilizations of Ancient Egypt and the Roman Empire.
Traders have also been influential in documenting food networks. Early Indian merchants and traders mapped the location of trading posts associated with food production nodes. Thomas Malthus famously stated that food output could only expand arithmetically in proportion with the extension of farmland while population could increase geometrically, leading to a 'population bomb' or a Malthusian catastrophe.
His theory was also given a spatial element when he predicted the Irish potato famine — a situation in which there was enough food within Ireland to feed the entire population, but access to food was limited.
Food production[ edit ] Food production was the first element of food to receive extensive attention from geographers in the field of cultural geographyparticularly in agricultural geography. Globally, the production of food is unequal. This is because there are two main components involved in sustenance production that are also distributed irregularly.
These components are the environmental capacity of the area, and the human capacity. Human capacity, in relation to food production, is the size of the population and the amount of agricultural skill within that population.
When these two are at ideal levels and partnered with financial capital, the creation of intense agricultural infrastructure is possible, as the Green Revolution clearly portrays. Simultaneously, the ability of a country to produce food is being severely impacted by a plethora of other factors: Pests are becoming resistant to pesticidesor pesticides may be killing off the useful and necessary insects.
Tanzania experienced a particularly horrible infection of armyworms in At the infections peak, there were over larva per square meter. InLiberia experienced a state of emergency when invading African armyworm caterpillars began what became a regional food crisis.
The caterpillars traveled through 65 towns and 20 people were forced to leave their homes, markets, and farms. Water stressdesertificationand erosion are leading to loss of arable land. Hydroelectric dams and mega-canal projects are becoming the new standard for countries like Egypt that can no longer depend on rainfall or natural flood cycles.
These water shortages are also causing a source of conflict between neighboring nations as they live with increasingly high levels of water scarcity. Policy responses to these events could be implemented in order to strengthen the socio-economic growth, human health statuses, and environmental sustainability of these areas.
Combining current limitations with water and transitions from practices such as agroforestry and shifting cultivation makes land susceptible to aeolian erosion by weakening soil composition and exposing larger areas of land to destructive wind.
Climate change is creating more extreme weather patterns, and agricultural practices are estimated to cause from 10 to 12 percent of greenhouses gas emissions.Theme One - Location.
Location is an object’s position on the Earth’s surface. The absolute location of Greece is 39° N, 22° benjaminpohle.com relative location of Greece could be North of the Mediterranean Sea or to the East of Italy. Also, Greece is in the Northern Hemisphere.
The 5 Themes Of Geography On Greece.
Modern Greece’s 5 Themes of Geography Location Absolute Location of Greece: The absolute location of Greece is located at 39oN, 22oE because that’s where its capital, Athens, is located.
Location. Where is it? Absolute: A location can be absolute (specific) as in coordinates of a map using longitude and latitude. Relative: A location can be relative - examples: next door, nearby, a short drive, down the road a benjaminpohle.com, it can be in the same general location as another location - example: next to the post office.

Greece generally has a mild, Mediterranean climate, with July and August being the busiest months for tourism. With warm weather and plentiful sunshine, this is a great time for visiting the islands, swimming in the sea and lazing on the beach.
