Answer: An agricultural revolution or agrarian revolution is a period of transition from the pre-agricultural period characterized by a Paleolithic diet, into an agricultural period characterized by a diet of cultivated foods; or a further transition from a living form of agriculture into a more advanced and more productive form of agriculture, resulting in further social changes, and some argue worse individual living conditions. Examples of historical agricultural revolutions include: The Neolithic Revolution, the initial transition from hunting and gathering to settled agriculture in prehistory and developing the ability to farm crops. This period is commonly referred to as the 'First Agricultural Revolution'. The Arab Agricultural Revolution, diffusion of many crops and farming techniques across Arab world and Muslim world during Islamic Golden Age. The British Agricultural Revolution, an increase in agricultural productivity in Great Britain which helped drive the Industrial Revolution. The Scottish Agricultural Revolution, the British Agricultural Revolution in Scotland specifically, which led to the Lowland Clearances.
