Land Dynamics
Land is fixed in location and immobile. This fixed location attribute influences various utilization of land. According to Barlowe, this has a bearing on human decisions or preferences concerning the value and use-capacity of various places; land-utilization practices; private ownership, land values, uses, and ownership conditions to the local environment; and legal description of properties (1958).
On human decisions or preferences
Rational thinking and choices dictate that some portions of the earth’s surface are more advantageous than the others. These preferred areas gain economic significance and value when used by an individual or group of individuals to meet certain needs and demands. For example, a businessman would put up a business in a metropolis where he might expect the largest flow of customers and trade and thus the biggest yield. In such respect, said area has a locational advantage. An economic location is thus established by combining human choice and physical location. As Barlowe has explained:
The concept of economic location assumes that some areas enjoy locational advantages over the others. This advantage often involves savings in transportation costs and time; and it stems partly from the fact that the law of diminishing returns makes it both physically impossible and economically impracticable for man to produce all his market goods at points adjacent to a central market. Location advantages also result from the higher productivity and lower production costs associated with particular sites (1958:32).
Moreover, since most sites can accommodate only one use at a time, the need to link the fixed geographic or spatial relationships that separate various areas arises. This can be resolved by providing transportation means. In this respect, the area that has locational advantage is the one where there are savings in transportation costs and time. For instance, an individual would reside in a place near the office where he goes to work or near the shopping center where he buys his basic necessities. Such decisions may be based on his savings in transportation costs and time, whichever activity he values most.
On land-utilization practices
Relative to the above, land location prescribes the use of land. Different uses of land can be observed at varying distance from the market. Time, effort, and convenience are relevant factors that are considered in determining the use of a particular tract of land. As to the said factors for instance, maximum savings can be realized if heavy and bulky products are manufactured near the market.
On ownership and community ties
Because of fixed location factor, standardization of properties is impossible with parcels of land. This is because tracts of land “differ in location and have different neighbors and different spatial relationships with respect to other properties and facilities” (Barlowe, 1958: 36).
On legal description of properties
The fixed location factor helps in describing the location of various land holdings, which in turn facilitates the legal description of land titles.
von Thunen’s Theory
A German landowner and economist, Johann Heinrich von Thunen developed a model which attempts to analyze the relationship between differences in spatial location and land utilization patterns. The von Thunen’s Model illustrates the effects of location relative to market, and transportation facilities and costs, on land utilization practices.
According to von Thunen, transportation costs include not only the transfer of produce to market, but also the time, effort, and inconvenience associated with moving workers and supplies to and from various production sites. With this, he argued that the first zone would be used for garden plots and other intensive uses which call for considerable care and travel on the part of the villagers. The second and third zones were devoted to uses involving heavy, bulky, and hard-to-transport commodities while those uses involving more easily transported products were located at even greater distances from the city.
Nowadays, some of the von Thunen’s assumptions do not hold true due to modern transportation facilities. But it is still advantageous to locate a production area near the market wherein transportation costs can be reduced at the minimum level or better yet, none at all.
Central Place Theory
About seventy years have now passed since Walter Christaller established the foundations of Central Place Theory in his book entitled Die zentralen Orte in Süddeutschland. The Central Place Theory has played an important role in the explanation of urban system. It attempts to explain the size, number, and spatial distribution of settlement in the belief that some ordering principles govern the distribution.
The Central Place Theory posits the following:
· that the basic function of a city is to be a central place which provides goods and services for a surrounding tributary area;
· that the centrality of a city is a summary measure of the degree to which it is such a service center;
· that higher order places offer more goods, have more establishments and business types, larger populations, tributary areas and tributary populations, do greater volumes of business, and are more widely spaced than lower order places;
· that low order places provide only low order goods to low order tributary areas;
· that central places fall into a hierarchy comprising discrete groups of centers; and
· that the hierarchy may be organized according to marketing, traffic, and separation principles (Berry and Pred, 1965: 3).
The central place is specialized in selling various goods and services. As such, the city, which serves as a central place, has a number of smaller towns at an equal distance away from it, and is located at the center of minimum aggregate travel of its tributary area.
The more central the place is, the higher is its “order”. High order centers (e.g., universities) provide highly specialized goods and services while low order ones (grocery stores) offer simple basic goods and services, which require frequent purchasing with little consumer travel.
High order centers perform all the functions of low order centers plus a group of central functions that differentiates them and sets them above the lower order. This implies that there are low order goods and services in high order centers but not high order goods and services in low order centers. A result is a “nesting” pattern of lower order trade areas within the trade area of higher order centers, plus a hierarchy of routes joining the centers.
Based on the Central Place Theory, the larger the settlements, the lesser their number; the bigger a settlement, the farther away a similar size settlement is; the larger the settlement, the higher the order of its services; and the range (or the maximum travel distance of a consumer) increases as the population increases.
The conurbation is the largest settlement, so has the largest amount of services and therefore there are less of them. The towns, on the other hand, have much less services and there are more of them.
The Central Place Theory assumes that all areas have an isotropic surface, an evenly distributed population and resources, and similar purchasing power of consumers. It points out that to prevent spheres of influence to overlap or have gaps, the best shape is a hexagon. The breaking point is where the consumer is equidistant from two/more similar services.
