Agricultural Production Regions

Major Agricultural Production Regions Around the World

All agriculture has the same ultimate goal—cultivating food. Whether or not it's primarily for money is where the difference lies between agriculture in different areas of the world. Agricultural production regions are divided into commercial and subsistence agriculture dominant, discussed next.

Commercial Agriculture Dominant

When crops are grown or animals raised primarily to make money, that's commercial agriculture. Commercial farms are businesses, and their products can be shipped to faraway places. Commercial agriculture is dominant in more-developed countries (MDC)s. Because the food supply is abundant, most people in MDCs do not have to work in agriculture, and farmers can focus on growing crops that pay well.

MDCs can have greater crop yields because of the widespread adoption of agricultural technology and government subsidies for agriculture. The worse economic conditions in some LDCs make technological advancements and financial aid less widespread, and therefore commercial agriculture is less dominant.

The regions of the world that are commercial agriculture dominant include the Americas, Europe, and most of East Asia. One commercial agriculture dominant country is Canada. Let's explore in more detail what agriculture looks like in Canada.

Commercial Agriculture in Canada

Canada's economy today is dominated by the service and secondary sectors, with agriculture accounting for about 1.6% of its GDP in 2017. Its largest crop is wheat, and most of its crops are exported to other countries, with the United States being its largest export partner. The shipping of agricultural products is a significant feature of commercial agriculture dominant regions and indicative of the food not being produced just for the farmers and their communities.

Subsistence Agriculture Dominant

When the primary purpose of a farm is to feed its farmer and family or community, it's known as subsistence agriculture. Subsistence farms produce enough to provide nourishment and food security, with little left to be sold at the market. Subsistence-dominant areas are primarily found in the developing world, where food insecurity is rampant. Food insecurity in LDCs leads a large portion of the workforce to work in agriculture, much more than the proportion in MDCs.

Subsistence farms vary in size but generally are smaller than commercial farms. Subsistence farms might also not be privately owned—they can be owned collectively by a community where everyone takes part in running it. A feature of subsistence farms is mixed cropping, meaning multiple crops are grown at once. This stands in contrast to monocropping, where a single crop is planted. Because the goal is to provide nourishment and not make money, different types of foods are grown to meet those nutritional needs.

Parts of the world that are subsistence agriculture dominant include sub-Saharan Africa and portions of South Asia and South America. The prevalence of subsistence agriculture worldwide is declining, with factors like urbanization and industrialization leading to people leaving rural areas. In addition, the spread of agricultural technology led to increased yields, meaning more food sold and fewer people needed to tend fields.

Why Subsistence Agriculture?

Because of the monetary benefits of focusing on commercial production, it's easy to wonder why subsistence agriculture still exists in the 21st century. As previously stated, economic conditions are a significant driver of why people turn to subsistence agriculture, but tradition and way of life are huge factors too. For some communities, participation in farm work and growing what you eat is a vital part of the culture. In the United States, for example, some Native American tribes maintain nomadic herding and subsistence agriculture practices due to tradition. In some cases, promoting subsistence agriculture is a solution to solving food insecurity.

Major Agricultural Production Regions of the USA

Agriculture in the United States changed and adapted throughout the centuries. Today, a small portion of the population works on farms, but the amount of food produced is more than at any time in history. Agriculture in the USA is overwhelmingly commercial, having changed from subsistence driven during the Industrial Revolution. Next, let's discuss some major agricultural production regions of the USA.

Crop Producing Regions

You may have heard jokes that if you go on a road trip to Iowa or Illinois, all you see are cornfields. While there's definitely more than that, the jokes aren't entirely unfounded! The largest crop-producing regions of the US include the midwest and Great Plains. The most-produced crops in the United States are corn, soybeans, and wheat. These regions ended up dominating crop production primarily due to favorable soil and climate conditions. The advent of fertilizers, pesticides, and farming technology on top of the already excellent growing conditions means the midwest and Great Plains are now highly productive agriculture regions.

Central California is another major crop-producing region, focusing on fruits and vegetables you're likely to see in the produce section of a supermarket. Because of Central California's year-round warm weather, it supplies fresh fruit and vegetables to other parts of the country during the winter.

Livestock Producing Regions

Other parts of the United States are more suited to raising animals. In places like West Texas, soil conditions made growing crops nearly impossible, but the ample land made maintaining herds of cattle feasible. Today, livestock production is widely geographically dispersed, with indoor animal husbandry enabling them to thrive regardless of climate conditions. By the number of animals, chickens occupy the largest livestock group in the US, with some raised for meat and others for eggs. The second is cows, for both dairy and meat.

There are many ways to measure agricultural production in the United States—total value of what's grown, the number of people who work on farms, total farm acreage—but let's look at a map of what land is dedicated to crops first.

As we can see, cropland in the United States is concentrated around the midwestern states and central great planes, with California's Central Valley also a notable spot.

Climatic Zones and Agricultural Production Regions

Plants rely on sunlight and water to grow, and the environment they're grown in is the biggest factor in how well they will thrive. Climate refers to the long-term weather patterns of a region and is affected by things like elevation and distance from the equator. The amount of rainfall, sunlight, and temperature define a region's climate and, thus, its agricultural potential.

The most widely used system for categorizing climatic zones is called the Köppen climate classification. Based on a region's rainfall and temperature, it's divided into five climate categories: tropical, dry, temperate, continental, and polar. Let's discuss some of these climate regions and what crops are produced there next.

Tropical Agriculture

Tropical areas have abundant heat, sunlight, and rainfall. It's unsurprising, then, that tropical regions are home to all kinds of crop production. Fruits, vegetables, trees, grains, and much more are cultivated in tropical areas, and the absence of harsh winters means the growing season is year-round. However, tropical regions are beset by some extra challenges, including high pest populations owing to the favorable climate. Additionally, some plants and animals are heat sensitive, meaning the high temperatures are not conducive to their thriving.

Temperate and Continental Agriculture

Temperate and continental climates differ from tropical climates in that there are distinct seasons, each with a variation in temperature and rainfall. The different seasons mean that a different crop is grown during wintertime, or nothing can be grown at all. Crops in these regions include corn, soybeans, rice, and some hardier vegetables. A major advantage of farming in these regions as opposed to tropical ones is that soil quality is often better, and low winter temperatures kill off pests, lowering their overall populations.
