Why Is Agriculture Important? Benefits and Its Role

Tables of Contents

When people think of agriculture, they often envision crop farming: soil and land preparation and sowing, fertilizing, irrigating, and harvesting different types of plants and vegetation.

However, according to the U.S. Census Bureau’s North American Industry Classification System (NAICS), crop farming is just one element of the Agriculture, Forestry, Fishing, and Hunting sector. Agriculture also encompasses raising livestock; industrial forestry and fishing; and agricultural support services, such as agricultural equipment repair and trucking operations.

Why is agriculture important? It helps sustain life by providing the food we need to survive. It also contributes $7 trillion to the U.S. economy. Despite agriculture’s importance, the Economic Policy Institute reports that farmworkers are among the lowest-paid workers in the U.S.

However, agriculture also provides opportunities for economic equity and helps people prosper around the world. For example, since 2000, the agricultural growth rate in Sub-Saharan Africa has surpassed that of any other region in the world (approximately 4.3% annually), contributing to the region’s economic gains, according to the United States Agency for International Development (USAID). While there’s been a global decline in agricultural jobs — from 1 billion in 2000 to 883 million in 2019, according to employment indicators from the Food and Agriculture Organization of the United Nations — agriculture remains the second-highest source of employment (26.7% of total work).

Agriculture is the practice of cultivating natural resources to sustain human life and provide economic gain. It combines the creativity, imagination, and skill involved in planting crops and raising animals with modern production methods and new technologies.

Agriculture is also a business that provides the global economy with commodities: basic goods used in commerce, such as grain, livestock, dairy, fiber, and raw materials for fuel. For example, fiber is a top crop in U.S. agricultural production, according to The Balance Small Business, and a necessary commodity for the clothing sector.

A key to why agriculture is important to business and society is its output — from producing raw materials to contributing to the global supply chain and economic development.

Raw materials are a core building block of the global economy. Without access to raw materials, manufacturers can’t make products. Nonagricultural raw materials include steel, minerals, and coal. However, many raw materials derive from agriculture — from lumber for construction materials to herbs for adding flavor to food. Corn, for example, is used to produce foods and serves as a foundation for ethanol, a type of fuel. Another example is resins: plant products used in various industrial applications, such as adhesives, coatings, and paints used in construction.

Importing and exporting goods such as agricultural products requires shipping methods such as ocean freight, rail, and trucking. Delays in shipping agricultural products from a Los Angeles port can create problems in China, and vice versa, impacting the global supply chain.

For example, sales of soybean crops from Iowa skyrocketed in 2021 due to various factors including delays in South American crop shipments, according to the Iowa Soybean Association. In this example, Iowa benefited from a competitive standpoint. However, delays in shipping crops could also be detrimental to regions expecting shipment, limiting availability of products on store shelves and affecting livelihoods.

Agriculture impacts global trade because it’s tied to other sectors of the economy, supporting job creation and encouraging economic development. Countries with strong agricultural sectors experience employment growth in other sectors, according to USAID. Countries with agricultural productivity growth and robust agriculture infrastructure also have higher per capita incomes, since producers in these countries innovate through technology and farm management practices to boost agricultural productivity and profitability.

The following resources provide information about the importance of agriculture as a source of raw materials and its impact on transportation and contribution to economic development:

When global supply chains are disrupted, considerable attention is given to the technology sector. For example, the lack of computer chips — made from silicon, a nonagricultural raw material — limits a manufacturer’s ability to make computers, cars, and other products. This impacts many areas of society and business.

Agriculture also plays a central role in meeting consumer and business market demand in a world with interconnected economies. Here are different types of products derived from agriculture.

Fruits and vegetables are essential sources of fiber, proteins, and carbohydrates in human diets. Vitamins, such as A, C, and E, and minerals, such as magnesium, zinc, and phosphorus, are naturally occurring in many fruits and vegetables. In addition to health benefits, fruits and vegetables add flavors to the human palette.

Some fruits and vegetables are grown to provide feed for animals, from poultry to livestock. The American Industry Feed Association reports that about 900 animal feed ingredients are approved by law in the U.S. These include ingredients that come from agricultural production, including hay, straw, oils, sprouted grains, and legumes.

The number of vehicles in the world is more than 1.4 billion, according to Hedges & Company market research. Every single one runs on rubber tires. According to GEP, the top rubber-producing countries are Thailand, Indonesia, and Malaysia — collectively representing approximately 70% of global natural rubber production — and about 90% of suppliers are small-scale farmers.

From cotton to clothes, the journey starts with agricultural production. Cotton is grown, harvested, and then processed, spun, and woven into fabric before it becomes a piece of clothing. Cotton production encompasses an expansive global supply chain, and according to Forum for the Future, it’s a leading commodity, making up approximately 31% of all textile fibers globally.

The U.S. Environmental Protection Agency (EPA) reports favorable economics of biofuels, produced from biomass sources including agricultural products such as corn, soybeans, sugarcane, and algae. The benefits include reduced greenhouse gas and pollutant emissions and the potential for increased incomes for farmers. However, biodiesel production requires the use of land and water resources that can affect food costs.

Bio-based chemistry involves using raw materials derived from biomass to develop industrial products. Different industrial products derived from bio-based chemicals include bioplastics, plant oils, biolubricants, inks, dyes, detergents, and fertilizers. Bio-based chemicals and products offer an alternative to conventional products derived from petroleum products. Bio-based chemistry is considered a type of green chemistry because it promotes the reduction of environmental impacts in industrial production.

For thousands of years, humans have turned to plants to help treat what ails them. For example, ginger, a plant root typically consumed in tea, can help aid digestion. Substances derived from plants and herbs can also help in healthcare. For example, extracted chemicals from the foxglove plant are used for digoxin, a drug used for heart failure. Another example is polylactic acid (PLA), a chemical produced when glucose is fermented into lactic acid in green plants. PLA has applications in tissue engineering, cardiovascular implants, orthopedic interventions, cancer therapy, and fabrication of surgical implants, according to a study published in Engineered Regeneration.

For thousands of years, agriculture has played an important role in everyday life. Before agriculture, hunting and gathering enabled humans to survive. It wasn’t until the transition to the planned sowing and harvesting of crops that humans began to thrive. Humans developed tools and practices to improve agricultural output with more efficient means of sustaining themselves. From there, innovations that created industries led to the modern era.

Today, the importance of agriculture in everyday life can’t be minimized. Without the agriculture sector, activities such as getting dressed for work and cleaning the home wouldn’t be possible. Here are examples of the agricultural products we use in our everyday lives:

Agriculture can have a significant effect on the economy. The U.S. Department of Agriculture (USDA) Economic Research Service reports that agricultural and food sectors provided 10% of all U.S. employment in 2020 — nearly 20 million full- and part-time jobs. Additionally, the USDA reported that cash receipts from crops totaled nearly $198 billion in 2020. Animal and animal product receipts weren’t far behind in 2020, totaling $165 billion.

The interdependence of the food and agriculture sector with other sectors, including water and wastewater systems, transportation systems, energy, and chemical, makes it a critical engine for economic activity, according to the Cybersecurity and Infrastructure Security Agency (CISA).

Agriculture also impacts economic development by contributing to the overall U.S. gross domestic product (GDP), directly and indirectly. It does so through farm production, forestry, fishing activities, textile mills and products, apparel and food and beverage sales, and service and manufacturing.

Here are ways agriculture and related industries impact economic development:

Agribusiness consists of the companies that perform the commercial activities involved in getting agricultural goods to market. It includes all types of businesses in the food sector, from small family farms to global agricultural conglomerates. In the U.S., farms contributed about $136 billion to GDP (about 0.6% of total GDP) in 2019, according to the USDA.

However, farms are just one component of agribusiness. Agribusiness also includes businesses involved in manufacturing agricultural equipment (such as tractors) and chemical-based products (like fertilizers) and companies involved in the production and refinement of biofuels. USDA data reports that in total, farms and related industries contributed more than $1.1 trillion to GDP, a little over 5% of the GDP, in 2019.

The economics of agribusiness also entails building production systems and supply chains that help maintain a country’s economic and social stability. Through the development of organizational and technological knowledge, agribusiness plays a vital role in protecting the environment and biodiversity near farms and using natural resources sustainably.

Food security is central to the agricultural industry: Sustainable agriculture is a key to fulfilling the United Nations’s Sustainable Development Goals (SDGs), including SDG 2: Zero Hunger. In addition to food security, the agricultural sector raises the incomes among the poorest communities up to four times more effectively than other sectors, according to the World Bank.

Throughout the world, agriculture plays an important role in job creation. For example, agriculture accounts for 25% of exports in developing countries in Latin America, about 5% of their regional GDP, according to a report about the importance of agribusiness from BBVA, a corporate and investment bank. This activity is a source of economic activity and jobs in these countries. In the U.S., agriculture and related industries provide 19.7 million full- and part-time jobs, about 10.3% of all employment.

Advanced farming equipment and the increased use of fertilizers and pesticides have resulted in higher crop yields. At the same time, they’ve impacted the environment, contributing to soil and water pollution and climate change. NASA projects a 24% decline in corn crop yields by 2030, thanks to climate change. However, ensuring a healthy biodiversity can help mitigate the impact. Here are some factors to consider:
