Peoples (de Blij & Murphy)
1)
Primary Activities
– the extractive sector; direct extraction of natural resources from the
environment; hunting and gathering, herding, fishing, mining, lumbering,…
2)
Secondary Activities
– the manufacturing sector; processes raw materials and transforms them into
finished industrial products; production of an almost infinite range of
commodities (toys, chemicals, buildings, …)
3)
Tertiary Activities
– the service sector; engaged in services; transportation, banking, education,
…)
4)
Quaternary –
concerned w/ collection, processing, and manipulation of information &
capital (finance, administration, insurance, legal services)
5)
Quinary – require a
high level of specialized knowledge or skill (scientific research, high-level
management)
1)
Agriculture – the deliberate tending of crops and livestock in order to
produce food and fiber.
2)
Before farming – a recent innovation (12,000 yrs.), hunting and
gathering – have been forced into more difficult environments; agriculture
permitted people to settle permanently with the assurance food would be
available (storage)
3)
Before farming: early
communities improved tools (sticks, baskets), weapons (clubs, spears),
innovations (fire)
a)
Metallurgy: separating
metal from ores, developed prior to plant & animal domestication
b)
Fishing – after Ice Age
(12,000 – 15,000 yrs ago), coastal regions become warmer

Alternating periods of
plenty and scarcity
4)
1st
Agricultural Revolution: 12,000 yrs ago (Neolithic Era)
a)
Accompanied by a modest
population explosion
b)
Domestication – animal
(about 40 species today) occurred after people became more sedentary
5)
Subsistence farming:
self-sufficient, small scale, low technology; food production for local
consumption, not for trade (Central & South America, Subsaharan Africa, S.E.
Asia)
a)
Some are confined to
small fields; very likely they do not own the soil they till
b)
Can promote cohesiveness
w/in society, share land, food surpluses, personal wealth is restricted;
cultivators are poor – but free
c)
Shifting Cultivation –
(slash & burn) Cultivation where tropical forests are removed by cutting
& burning, ash contributes to soil fertility; clearings are usually
abandoned after a few years for newly cleared land (150-200 million people)

19: Rural Settlement Forms
Attributes
1)
Form – influenced by culture, environment,…
2)
Function – impression of social and economic needs (eg. livestock under same
roof as people in
3)
Materials – reflect local availability (not as important as it was in the
past: why?) and purpose
4)
Spacing – relationship between density of houses and intensity of crop
cultivation
a)
Dispersed settlement – houses lie far apart from each other (eg. US
b)
Nucleated (agglomerated) settlement – compact, closely packed settlement
sharply demarcated from adjoining farmlands (eg. Java; most prevalent
residential pattern in rural areas, land use is just as intense)
The
first topic in Chapter V of the summary outline, the development and diffusion
of agriculture, is covered well in most human geography textbooks. Most
textbooks follow the presentations of economic land agricultural activity that
is based on the notions of the nineteenth-century geographer Edward Hahn that
were modified and further articulated in the
Neolithic Agricultural Revolution
There
are major events in the history of the world that are quite transforming; the
invention of agriculture in the Neolithic times was one of those events. The
invention of agriculture enabled the human population to differentiate itself
from the higher primates. By applying agricultural technologies in very simple
forms, humans were able to increase the carrying capacity of the earth's surface
by many, many times. Every culture on the surface of the earth engages in
agriculture in some form. We obviously need food to eat, and cultures have
developed practices for storing food until times of shortage and for moving food
from areas of high productivity to areas of high consumption.
In
addition to the circulation of food, other aspects of food production attract
the attention of human geographers. The spatial patterns of the dietary laws
that govern consumption and production of crops and animals around the world
have fascinated many geographers. Carl Sauer's seminal work, the Agricultural
Origins and Dispersals, published by the American Geographical
Society in 1952, is the springboard for all contemporary geographical
discussions about the origins of agriculture. Sauer believed there were eleven
separate centers of plant and animal domestication. This great invention
probably occurred first in the areas of the tropical seashores where settled
fishermen were able to produce enough surplus so that they could invest some of
their wealth and time into the experimentation and nurturing of plants and
animals. Sauer and others argue that large herd animals may have been
domesticated first for ceremonies and then later used for other purposes. They
conclude this because the religious personages in the early agricultural
communities had the time to rear young herd animals to the stage at which they
could actually participate in religious ceremonies. But of course, no one really
knows for sure. The movement of humans around the surface of the earth diffused
plants and animals to nearly every possible environment. Some of the movements
are well documented; others are only vaguely understood.
Evolution
of Energy Sources and Technology
The
increasing availability of animal energy expanded humans' ability to till the
soil. Techniques of harnessing animals evolved from the early forms of
tying plows to the heavy horns of cattle to the advanced harnessing system for
horses. Europeans developed the heavy horse collar which enabled the weight that
the animals were pulling to be transferred to their powerful shoulders and away
from their windpipe and neck. This made the horse much more effective. The use
of large draft horses enabled farmers to till heavier, more productive soils,
which ensured better yields of grain. Better yields meant more food for animals
and eventually large, more powerful animals. Although agricultural technology
evolved in all parts of the world, the process was slow. Farmers were reluctant
to experiment with new, risky ventures for fear of crop failure and famine.
Regions
of plant and animal domestication
All
the popular textbooks and atlases have maps and charts that portray the assumed
regions of plant domestication. These maps are important because they illustrate
the areas where the wild ancestors of modern crops might be found. The genetic
material in the world of our ancestors is considered precious, because it is
essential for creating new varieties of domesticated plants.
Agricultural Systems Associated with Major Bio-Climatic Zones
There
are two things that must be considered when teaching the contemporary regional
patterns of agricultural production. One is the relationship between agriculture
systems and the climatic zones, and the second is the complicated set linkages
among the production areas and the consumption areas. All forms of economic
activity are involved in the shift of agriculture products to food.
Most
atlases and textbooks contain a version of a map based on the map drawn by
Derwent Whittlesey and published by the Annals
of the Association of American Geographers in1936. Unfortunately, no
agricultural geographer has attempted to modernize this map, and therefore it
must be used with caution. This map attempts to portray the major agricultural
regions in the world. One way to deal with this part of the course is to have
your students study this map making sure they understand the key. The map shows
a pattern of about thirteen varieties of agriculture that reflect environmental
zones. For example, the nomadic herders are found in the arid regions of north
and
What
Whittlesey calls rudimentary
sedentary cultivation really should be thought of as subsistence
agriculture. Another of his categories is intensive
subsistence tillage, one form making heavy use of rice and another
form really using wheat rather than rice. These circulation systems are
essentially the same, but each utilizes a little different crop mixture due to
the climatic differences. Livestock ranching, like nomadic herding and shifting
cultivation, does seem to follow major climatic zones.
If
students look at the map with some fundamental understanding of environmental
zones, they will see very clear patterns. However, this map is only the
beginning, because farmers have greatly modified the environment and even
destroyed major components of it to bring this pattern into reality. The forests

Currently,
there is controversy about the flow of food around the world. Many governments
think of food as a strategic material and want to ensure that their local
production is adequate should warfare interrupt the flow of international trade.
In
addition, farmers using their political clout have raised barriers to prevent
the import of food from areas in which food is produced more efficiently. One of
the significant developments in international trade and food in the 1990s has
been the growing resistance in
Land
Use and Location Models
Like
other forms of economic activity, agriculture is influenced by transportation
costs or the friction of distance. The major variable of bio-climatic influences
is modified by the accessibility factor. It has been observed many times that on
areas of seemingly homogeneous landscape, a pattern of land use will have
developed that is dependent upon transportation costs.
The
most fundamental model of that pattern was developed by von Thunen in the
nineteenth century to describe and explain land uses on the north German plain.
The von Thunen model has been described in all the popular textbooks. The
illustration presented here is one of many. The important thing about the von
Thunen model is the way in which it enables students to think about
accessibility and to break free from explanations of agriculture that are based
on out-moded notions of ethnicity and environmental determinism. The model is
particularly useful in explaining the sequence of agriculture that occurred with
the settlement of

areas. An average-sized farm in
The
von Thunen Model Explained
The
von Thünen model of agricultural land use was created by farmer and amateur
economist J.H. Von Thünen. His model was created before industrialization and
is based on the following limiting assumptions:
In
an
There
are four rings of agricultural activity surrounding the city. Dairying and
intensive farming occur in the ring closest to the city. Since vegetables,
fruit, milk and other dairy products must get to market quickly, they would be
produced close to the city (remember, we don't have refrigerated oxcarts!)
Timber
and firewood would be produced for fuel and building materials in the second
zone. Before industrialization (and coal power), wood was a very important fuel
for heating and cooking. Wood is very heavy and difficult to transport so it is
located as close to the city as possible.
The
third zone consists of extensive fields crops such as grains for bread. Since
grains last longer than dairy products and are much lighter than fuel, reducing
transport costs, they can be located further from the city.
Ranching
is located in the final ring surrounding the central city. Animals can be raised
far from the city because they are self-transporting. Animals can walk to the
central city for sale or for butchering.
Beyond
the fourth ring lies the unoccupied wilderness, which is too great a distance
from the central city for any type of agricultural product.
Even
though the Von Thünen model was created in a time before factories, highways,
and even railroads, it is still an important model in geography. The Von Thünen
model is an excellent illustration of the balance between land cost and
transportation costs. As one gets closer to a city, the price of land increases.
The farmers of the
Settlement
Patterns and Urban-Rural Connection
About
half the world's population still lives in rural regions dominated by
agriculture. The architecture of these settlements varies from place to place,
although it is possible to see broad patterns. The building materials
reflect local conditions as well as the availability of commercially produced
products from elsewhere. There is a relationship between the form of the
architecture and the function that is quite visible in certain areas. Because
most agriculturists live in villages, it is important to view in some detail the
nature of these rural settlement patterns.
Villages
are frequently referred to as nucleated
settlements. This is in contrast to dispersed
settlement, which is the basic pattern that exists in the
Environmental
and Social Impacts of Intensification
Nucleated
settlements, in general,
conform to fundamental cultural features in the landscape. They reflect the
social structure within the village, as well as the local environmental
situation, such as road, dike, or levy along a river. Most frequently, the older
villages were defensive in nature. The houses were close together and surrounded
by some sort of wall Even though the threat of invasion is over in most
places, these villages persist in their compactness and lack of a regular street
pattern.
Geographers
have classified villages according to their shape or form. Linear villages, with
houses lined up along a road are called strassendorfs.
Other villages are described as round
village, a cluster
village or a walled
village. The village pattern was, of course, transferred to the
In
various part of the world, agriculturists built villages using materials that
were at hand. In areas where there was plenty of wood, the houses were
built of wood. Where wood was not available, farmers used various types of
brick. Sun-dried brick, or adobe, is very common in the sunny areas. Fired,
or baked brick, is more common in the areas where the adobe is less
suitable. Houses were also built of stone, and in some locations, poles and
sticks were woven together and plastered over with mud.
The
basic point of all this is that agriculturists were close to the environment and
used whatever materials they had at hand. As transportation improved and
manufactured products could be brought into areas, vernacular styles and
building materials tended to disappear under the pressure of mass production.
The
size and the structure of villages and other forms or rural settlement reflect
the availability of space and local environmental conditions. The North American
farmstead is larger than many villages in
Introduction
to Modern Agriculture
The
second agricultural revolution reached its peak during the hundred and fifty
years from the post Civil War era to 2000. This period saw the development of
barbed wire, various forms of harvesting machines (particularly Cyrus
McCormick's reaper), and the tractor — first with a steam engine and then
with a gasoline engine — which replaced draft animals. The revolution's major
impact was the reduction in the number of people needed to operate farms.
The
third agricultural revolution, beginning approximately about 250 years after the
start of the second, has three distinctive features. The first is the removal of
the lines between agriculture as a primary activity and secondary and tertiary
activities. Farmers and agriculturists now engage in the primary activity of
crop production, some sort of secondary activity of manufacturing or processing
the crops, and tertiary activities of marketing and advertising their products
through co-ops and other marketing organizations. The second distinctive feature
of this agricultural revolution is more intensive mechanization; biotechnology
is the third. Mechanization began replacing animal and human labor in the
The
biotechnological phase began with chemical farming — the substitution of
inorganic fertilizers and manufactured products for manure and humus to increase
soil fertility. Chemicals were also used to control pests, and a wide variety of
herbicides, pesticides, and fungicides have been produced in a never-ending
effort to enhance the yields. This became widespread in the
Food
processing — adding economic value to agriculture products — is the third
part of the revolution, and the part that is achieving (or attracting or
gaining) the most energy and investment. While the first two phases of the
revolution are focused on inputs into the agricultural process, the third is
focused on output. Farmers frequently talk about the third phase as "value
added," and of course it's the third part that involves agriculturists in
secondary and tertiary activities. One of the indications of this has been the
use of the term "agribusiness" in the United States to describe the
blending of old agricultural farm-centered cultures to this new, more integrated
form of production and culture. One of the most significant features of the
third revolution is the elimination of the difference between urban and rural
life styles.
The
industrialization of agriculture in general has caused a number of changes in
agrarian societies. First, there has been change in the application of rural
labor as machines replace or enhance the efficiencies of human labor. In a
sense, the industrialization of agriculture creates surplus labor in the rural
areas that can be used for other urban activities. Second, there is the
development and introduction of new and innovative inputs such as seeds,
chemicals, and different kinds of technologies that supplement or replace
locally produced products. Third, there has been a development of substitutes
for some kinds of agricultural products. Fourth, new uses for agricultural
products have been developed. The conversion of corn to sugar for use in soft
drinks is an example.

Consumption,
Nutrition, and Hunger
Despite
the dramatic increase in food supply and reduction in hunger in the world as a
result of the diffusion of Green Revolution technology, there have been numerous
people who have found reasons to criticize this innovation. The division between
rich and poor that existed in the rural areas of the developing countries was
made wider by the Green Revolution. Some observers argue that the economic
conditions that arose from the political power created by the Green Revolution
more than offset the gains that were accomplished in increasing the food supply.
Others argue that the crops produced by with Green Revolution technology are
less nutritious, less flavorful, and less palatable. They also point out that
the fertilizers and chemicals used in the revolution come from fossil fuel, a
nonrenewable resource. Critics also feel that the Green Revolution can increase
erosion and environmental contamination. The need for capital from the West to
implement the changes to infrastructure has put pressure on the economies
to grow more crops for export and take land away from production of crops for
local consumption. It's also pointed out that the Green Revolution focus has
been on rice, corn, and wheat, which are crops that are of particular interest
in
Whatever
the critics say, it is clear the Green Revolution was successful. The countries
in which it was put into place have been able to feed their populations. While
the technology may have created problems, the alternative would be food
shortages and hunger. Neither is a viable alternative.
The
latest revolution in agriculture is being spread about the world from the core
to the periphery through a variety of agencies. First among these agencies are
the international efforts developed by the core nations over the years,
primarily the World Trade Organization (WTO), the European Union (EU), and the
North American Free Trade Agreement (NAFTA). These organizations promote the
diffusion of technology, but also support organizations that can usually be
called developmental.
Governments
have for many years regulated the flow of food goods in and out of their
countries to maintain production, consumption, and their own national corporate
profits. This is accomplished primarily by offering either direct or indirect
subsidies to agricultural producers to keep foodstuffs affordable. Over the
years, farmers in the
In
addition to being concerned with their internal food production, core states
have also engaged directly and indirectly in the agricultural sectors of other
nations. Aid for food and agriculture development is widespread and popular
around the world. When the receiving states asked for the aid, the charitable
organizations and the donor states were happy to send it. Many large-scale
agricultural development projects have been initiated around the world, but not
all been successful. One of the lessons learned from attempting to increase food
supply through external aid is that large-scale environmental modification
schemes generally have been unsuccessful. Small-scale projects sensitive to
local, cultural situations and environmental concerns seem to be more successful
over the long run.
Industrial/Commercial
Agriculture
A
useful way to envision the industrialization of agriculture is as a complex
circulation system based on the urban industrial cores. The nature of
agriculture changes and becomes more urbanlike as land devoted to agricultural
activities becomes more tightly connected to the urban industrial cores.
Agriculture has divisions of labor and the farm workers are not self-sufficient.
They buy their food in grocery stores, and get all the inputs from off-farm
sources.
When
thinking about the organization of industrial agriculture, the most important
concept is agribusiness.
This refers to a system of economic and political relationships that organize
food production from the development of the genetic makeup of the seeds to the
retailing and consumption of the agricultural product.
Agribusiness
is organized into flows of political and economic power that are focused on
commodity or food chains. A food chain is usually composed of inputs,
production, outputs, distribution, and consumption. There is an associated
landscape with each of these factors. Many of these commodity or food chains
link a variety of physical environments together. They also link areas of
production and consumption served by manufacturing areas.
In
a sense, agribusiness occurs at a global scale in the same way that a
subsistence village worked in the preindustrial area. In the subsistence
village, forms of production, processing, distribution, and consumption were
organized at the local scale. Occasionally, several villages interacted and
exchanged surpluses. Now, with industrialization and the intense increase in
circulation technology, entire regions of the world are linked together in the
form of production, processing, and consumption.
The
Europeans developed the first global system that linked together food production
in the colonial territories with consumption in the European sector. Early in
the colonial period, a food regime began in which wheat production in the
Environmental
Change — Desertification, Deforestation, etc.
As
we have seen, traditionally there is a correlation between types of agriculture
and bioclimatic zones. The growth of any organism in the plant kingdom is
dependent on water, solar energy, and nutrients from the environment. Therefore
the environment makes a major impact. By harvesting timber and grazing flocks in
the highlands, farmers modified the landscape around the
Perhaps
the most dramatic impacts have occurred on the margins of arid regions where
agriculturists, for a variety of reasons, have expanded into areas that have
thin topsoil and vegetation. Overgrazing and tillage caused a change in the
nature of this landscape that increased the rate of erosion thereby creating
desert-like soils on the surface. The desertification process was accelerated by
short-term climatic fluctuations in some areas, but primarily human activity is
the cause.
It's
a cliché to say that farmers have had more impact on the environment than any
other sector of the economy. Whether this is true or not is impossible to
measure. What is clear is that agribusiness has new ways, using biotechnology,
to modify the environment. Biotechnology refers to the process or the technology
that uses living organisms or parts of organisms to make or modify products, to
improve plants or animals, or to develop microorganisms for specific uses.
Biotechnology is distinct from the Green Revolution because it uses gene
manipulation, tissue cultures, cell fusion, embryo transfer, cloning, and a
variety of techniques unknown to the agriculturists of the 1950s. Biotechnology
has been able to produce what are sometimes called superplants that produce
their own fertilizers and pesticides and are resistant to disease an their
development of microorganisms. Through cloning, it is possible to take tissues
from one plant, insert them in another to form new plant, and produce millions
of identical plants thereby reducing the chances of variation in yields from
particular seeds.
While
the critics talk about cloned material making plants more susceptible to
diseases, elm trees with resistance to the Elm Virus have been successfully
cloned and planted in great numbers in the American Midwest. The debates about
biotechnology certainly are vociferous, and there is really no way for a
geographer to determine which side is going to be correct. It is clear that
biotechnology is a continuation of the industrialization of agriculture. It is
also based in private ownership and capitalism. Biotechnological processes are
patented. Seeds that are patented cannot be grown by the farmers unless they pay
the company that developed them. There are also some notions that if these crops
are exported to the developing world to increase the efficiencies in
agriculture, there will be a social disruption caused by the new seeds. As with
any change, there is no reason to expect its benefits will be equally
distributed. It seems the issue with biotechnology is what are the options of
not exporting these more efficient crops and not using this technology.
