Early agriculture represents a pivotal shift in human society, as it allowed our ancestors to transition from a nomadic, hunter-gatherer lifestyle to a more sedentary way of life. This momentous change was characterized by the cultivation of crops and the domestication of animals, which provided a reliable and consistent source of food for human populations.

However, the transition to agriculture was not without its challenges, as early farmers had to contend with changing climates, soil degradation, pests, and the development of social and economic systems to support food production. Despite these challenges, agriculture became the cornerstone of civilization, enabling the growth of complex societies, the formation of cities, and the development of trade and commerce. Early agriculture was not only a technological advancement, but a cultural and social one that transformed the way humans interacted with the natural world and with each other.

The ancient civilizations of Mesopotamia and Egypt were both reliant on agriculture, which formed the backbone of their economies. Despite facing harsh climatic challenges such as arid conditions, these societies developed innovative techniques and approaches to cultivate crops and raise livestock, enabling them to sustain and grow their populations.

The primary economic activity in ancient Mesopotamia was agriculture, and despite facing harsh constraints such as an arid climate, the Mesopotamian farmers developed effective strategies to sustain the development of the first states, cities, and empires. The economy was dominated by royal and provincial palaces, temples, and domains of the elites. The farmers focused mainly on cultivating cereals, particularly barley, and sheep farming, while also cultivating legumes, date palms in the south, and grapes in the north.

There were two types of Mesopotamian agriculture, which corresponded to the two primary ecological domains and overlapped with cultural distinctions. In southern or Lower Mesopotamia, which included Sumer and Akkad and later became Babylonia, irrigation was crucial due to receiving almost no rain, and the temple estates supervised large-scale irrigation works, which yielded high returns. In contrast, Northern or Upper Mesopotamia, the land that would eventually become Assyria, had enough rainfall to support dry agriculture most of the time, making irrigation and institutional estates less crucial, but the returns were usually lower.

On the other side, the ancient Egyptian civilization owed its prosperity to the Nile River, whose annual flooding provided fertile soil and predictability, enabling the Egyptians to establish a thriving agricultural-based empire. The Egyptians are renowned for being among the first to engage in agriculture on a large scale, due in part to their inventiveness in developing basin irrigation. Through this technique, the Egyptians were able to cultivate essential staple crops, such as wheat and barley, as well as important industrial crops, such as flax and papyrus.

The western Nile valley was once the home of several Neolithic cultures, where the Sahara’s vegetation was abundant during the African humid period around 8000 years BC. People lived by gathering wild cereals, including brachiaria, sorghum, and urochloa. However, as the African humid period ended around 6,000-5,000 years ago, migrating herders moved away from the region, including the Nile Delta, which had few indications of agriculture before that time.

Recent research in the Dakhleh Oasis provides crucial evidence of early Egyptian agriculture, which could be considered typical of Northeastern Africa’s post-Pleistocene developments. The Bashendi culture in Dakhleh, who were mobile herder-foragers during the African humid period, used sandstone grinders to grind local wild millet and sorghum, while other groups like the Bashendi inhabited Farafra Oasis and Nabta Playa.

Agriculture encompasses the cultivation of crops and livestock, aquaculture, fisheries, and forestry for food and non-food products. It was the primary catalyst in the emergence of sedentary human civilization as the farming of domesticated species generated food surpluses that allowed people to live in cities. Although grains were gathered by humans over 105,000 years ago, early farmers only began planting them roughly 11,500 years ago.

Meanwhile, the domestication of sheep, goats, pigs, and cattle took place about 10,000 years ago, and plants were independently cultivated in at least 11 regions across the world. In the 20th century, industrial agriculture based on large-scale monocultures became the dominant method of agricultural production.

Today, small farms are responsible for about a third of the world’s food, but larger farms are more prevalent. The top one percent of farms worldwide cover over 50 hectares and operate more than 70 percent of the world’s farmland. Almost 40 percent of agricultural land is found on farms larger than 1,000 hectares, while farms smaller than two hectares make up five out of every six farms in the world, occupying only about 12 percent of all agricultural land.

Primary agricultural products can be broadly categorized into foods, fibers, fuels, and raw materials such as rubber. Food types consist of cereals, vegetables, fruits, cooking oils, meat, milk, eggs, and fungi. Global agricultural production amounts to approximately 11 billion tonnes of food, 32 million tonnes of natural fibers, and 4 billion m3 of wood. However, roughly 14 percent of the world’s food is lost from production before reaching the retail level.

Although modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, and technological advancements have significantly boosted crop yields, they have also contributed to ecological and environmental harm. Selective breeding and contemporary animal husbandry practices have also increased meat production but raised concerns regarding animal welfare and environmental damage.

Environmental problems include contributing to climate change, depletion of aquifers, deforestation, antibiotic resistance, and other agricultural pollution. Agriculture is both a cause and a sensitive receptor of environmental degradation, such as biodiversity loss, desertification, soil degradation, and climate change, which can all decrease crop yield. Genetically modified organisms are widely utilized, though some nations prohibit their use.
