Chapter 10 Agriculture

I. Key Issue 1: Why Does Development Vary among Countries?

1. Origins of Agriculture

a) Hunters and Gatherers

• Before the invention of agriculture, all humans obtained food through

hunting for animals, fishing, and gathering plants.

• Hunters and gathers lived in small groups of usually fewer than 50 persons

because a larger number would quickly exhaust the available resources

within walking distance. The group traveled frequently, establishing new

home bases or camps.

• The direction and frequency of migration depended on the movement of

game and the seasonal growth of plants at various locations.

(1) CONTEMPORARY HUNTING AND GATHERING.

• Today, a quarter-million people still survive by hunting and gathering,

rather than agriculture.

b) Invention of Agriculture

• The agricultural revolution was the time when humans first domesticated

plants and animals, and no longer relied entirely on hunting and gathering.

• By growing plants and raising animals, humans created larger and more

stable sources of food, so more people could survive.

• Scientists do not agree on whether the agricultural revolution originated

primarily because the last ice age ended or people started wanting to live in

a permanent settlement.

• The agricultural revolution originated in multiple hearths around the world.

• Those agricultural hearths are Southwest Asia, East Asia, sub-Saharan

Africa, and Latin America.

• Animals were domesticated in multiple hearths as well.

• Inhabitants of Southwest Asia may have been the first to integrate

cultivation of crops, with domestication of herd animals such as cattle,

sheep, and goats.

• The horse is considered to have been domesticated in Central Asia.

• These animals were used to prepare the land before planting seeds.

• They were also fed the harvested crop.

• This integration of plants and animals is a fundamental element of modern

agriculture.

(1) TWO TYPES OF CULTIVATION.

(a) Vegetative planting

i) The reproduction of plants by direct cloning from existing

plants, such as cutting stems and dividing roots.

ii) The earliest form of plant cultivation, according to prominent

cultural geographer Carl Sauer.

(b) Seed Agriculture

i) Which is the reproduction of plants through annual planting of

seeds that result from sexual fertilization.

ii) Seed agriculture is practiced by most farmers today.

2. Location of Agricultural Hearths

a) Location of First Vegetative Planting

• Sauer believes that vegetative planting probably originated in Southeast

Asia

• The first plants domesticated in Southeast Asia through vegetative planting

probably included roots such as the taro and yam, and tree crops such as

the banana and palm.

b) Location of First Seed Agriculture

• Sauer identified three hearths in the Eastern Hemisphere—western India,

northern China, and Ethiopia

• Inhabitants of Southwest Asia also were first to integrate seed agriculture

with domestication of herd animals such as cattle, sheep, and goats.

• These animals were used to plow the land before planting seeds and, in

turn, were fed part of the harvested crop.

(1) DIFFUSION OF SEED AGRICULTURE.

• Seed agriculture di! used from Southwest Asia across Europe and

through North Africa.

• Greece, Crete, and Cyprus display the earliest evidence of seed

agriculture in Europe.

• Seed agriculture also di! used eastward from Southwest Asia to

northwestern India and the Indus River plain.

3. Classifying Agricultural Regions

a) Di! erences Between Subsistence and Commercial Agriculture

• In developing countries most people work in subsistence agriculture,

which is the production of food primarily for consumption by the farmer’s

family.

• Very few people in developing countries work in commercial agriculture

which is the production of food primarily for sales o! the farm.

• In developing countries, around 5 percent of workers are engaged directly

in farming, compared to 44 percent in developing countries.

• Both push and pull factors have contributed to the decline of farmers in the

United States.

• People were pushed away from farms by lack of opportunity to earn a

decent income and at the same time they were pulled to higher-paying jobs

in urban areas.

a) USE OF MACHINERY

• Beginning in the late eighteenth century, factories produced farm

machinery.

• Inventions in farming in the nineteenth and twentieth century made farming

less dependent on human and animal power.

• The building of railroads in the nineteenth century and highways and trucks

in the twentieth century have enabled farmers to transport crops and

livestock farther and faster.

• Experiments conducted in university laboratories, industry, and research

organizations generate new fertilizers, herbicides, hybrid plants, animal

breeds, and farming practices that produce higher crop yields and healthier

animals.

b) FARM SIZE

• The average farm is relatively large in commercial agriculture.

• Combines, pickers, and other machinery perform most e"ciently at very

large scales and their considerable expense cannot be justified on a small

farm.

• Farmers spend hundreds of thousands of dollars to buy or rent land and

machinery before beginning operations.

• Commercial farmers frequently expand their holdings by renting nearby

fields.

• The amount of land devoted to agriculture has increased in the United

States primarily due to irrigation and reclamation.
