Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output.
The Amazon rainforest, also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 6,000,000 km2 (2,300,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations and 3,344 indigenous territories.
Horticulture is the art and science of growing plants. This definition is seen in its etymology, which is derived from the Latin words hortus, which means "garden" and cultura which means "to cultivate". There are various divisions of horticulture because plants are grown for a variety of purposes. These divisions include, but are not limited to: gardening, plant production/propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges; Each requiring highly specialized skills and knowledge of the horticulturist.
Agriculture in Mesoamerica dates to the Archaic period of Mesoamerican chronology. At the beginning of the Archaic period, the Early Hunters of the late Pleistocene era led nomadic lifestyles, relying on hunting and gathering for sustenance. However, the nomadic lifestyle that dominated the late Pleistocene and the early Archaic slowly transitioned into a more sedentary lifestyle as the hunter gatherer micro-bands in the region began to cultivate wild plants. The cultivation of these plants provided security to the Mesoamericans, allowing them to increase surplus of "starvation foods" near seasonal camps; this surplus could be utilized when hunting was bad, during times of drought, and when resources were low. The cultivation of plants could have been started purposefully, or by accident. The former could have been done by bringing a wild plant closer to a camp site, or to a frequented area, so it was easier access and collect. The latter could have happened as certain plant seeds were eaten and not fully digested, causing these plants to grow wherever human habitation would take them.
The Three Sisters are the three main agricultural crops of various indigenous people of Central and North America: squash, maize ("corn"), and climbing beans. In a technique known as companion planting, the maize and beans are often planted together in mounds formed by hilling soil around the base of the plants each year; squash is typically planted between the mounds. The cornstalk serves as a trellis for climbing beans, the beans fix nitrogen in their root nodules and stabilize the maize in high winds, and the wide leaves of the squash plant shade the ground, keeping the soil moist and helping prevent the establishment of weeds.
The Neolithic Revolution, also known as the First Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period in Afro-Eurasia from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible. These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed. This new knowledge led to the domestication of plants into crops.
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time. A fertile soil has the following properties:
The founder crops or primary domesticates are a group of flowering plants that were domesticated by early farming communities in Southwest Asia and went on to form the basis of agricultural economies across Eurasia. As originally defined by Daniel Zohary and Maria Hopf, they consisted of three cereals, four pulses, and flax. Subsequent research has indicated that many other species could be considered founder crops. These species were amongst the first domesticated plants in the world.
Agroforestry is a land use management system that integrates trees with crops or pasture. It combines agricultural and forestry technologies. As a polyculture system, an agroforestry system can produce timber and wood products, fruits, nuts, other edible plant products, edible mushrooms, medicinal plants, ornamental plants, animals and animal products, and other products from both domesticated and wild species.
Bactris gasipaes is a species of palm native to the tropical forests of Central and South America. It is well spread in these regions, where it is often cultivated by smallholders in agroforestry systems or more rarely, in monoculture. Common names include peach palm in English, among others used in South American countries. It is a long-lived perennial plant that is productive for 50 to 75 years on average. Its population has an important genetic diversity, leading to numerous fruits, colors, and qualities. The fruits are edible and nutritious but need to be cooked for 30 minutes to five hours. They also benefit many animals in the wild. Peach-palms are also cultivated for the heart of palm, and the trunk can make valuable timber.
Terra preta is a type of very dark, fertile anthropogenic soil (anthrosol) found in the Amazon Basin. It is also known as "Amazonian dark earth" or "Indian black earth". In Portuguese its full name is terra preta do índio or terra preta de índio. Terra mulata is lighter or brownish in color.
Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming.
1491: New Revelations of the Americas Before Columbus is a 2005 non-fiction book by American author and science writer Charles C. Mann about the pre-Columbian Americas. It was the 2006 winner of the National Academies Communication Award for best creative work that helps the public's understanding of topics in science, engineering or medicine.
The Eastern Agricultural Complex in the woodlands of eastern North America was one of about 10 independent centers of plant domestication in the pre-historic world. Incipient agriculture dates back to about 5300 BCE. By about 1800 BCE the Native Americans of the woodlands were cultivating several species of food plants, thus beginning a transition from a hunter-gatherer economy to agriculture. After 200 BCE when maize from Mexico was introduced to the Eastern Woodlands, the Native Americans of the eastern United States and adjacent Canada slowly changed from growing local indigenous plants to a maize-based agricultural economy. The cultivation of local indigenous plants other than squash and sunflower declined and was eventually abandoned. The formerly domesticated plants returned to their wild forms.
New World crops are those crops, food and otherwise, that are native to the New World and were not found in the Old World before 1492 AD. Many of these crops are now grown around the world and have often become an integral part of the cuisine of various cultures in the Old World. Notable among them are the "Three Sisters": maize, winter squash, and climbing beans.
The Llanos de Moxos, also known as the Beni savanna or Moxos plains, is a tropical savanna ecoregion of the Beni Department of northern Bolivia.
William Maxfield Denevan is an American geographer. He is professor emeritus of Geography at the University of Wisconsin-Madison and is a prominent member of the Berkeley School of cultural-historical geography. He also worked in the Latin American Center and the Institute for Environmental Studies at Wisconsin. His research interests are in the historical ecology of the Americas, especially Amazonia and the Andes.
The Llanos de Moxos also known as the Moxos plains are extensive remains of pre-Columbian agricultural societies scattered over the Moxos plains in most of Beni Department, Bolivia. The remains testify to a well-organized and numerous indigenous people. This contradicts the traditional view of archaeologists, notably Betty Meggers, who asserted that the Amazon River Basin was not environmentally able to sustain a large population and that its indigenous inhabitants were hunter-gatherer bands or slash-and-burn farmers. In the 1960s, petroleum company geologists and geographer William Denevan were among the first to publicize the existence of extensive prehistoric earthworks constructed in the Amazon, especially in the Llanos de Moxos.
The history of rice cultivation is an interdisciplinary subject that studies archaeological and documentary evidence to explain how rice was first domesticated and cultivated by humans, the spread of cultivation to different regions of the planet, and the technological changes that have impacted cultivation over time.
Forest islands are atypical isolated stands of tropical forest on the Amazonian savanna. Their origin is largely unknown. One hypothesis suggests anthropomorphic origins, those forest islands being earlier human farming of diverse useful, food-producing tropical plants and trees, collected and willfully inserted in suitable points of the grassland.
