First Agricultural Revolution/Neolithic Revolution
During the Neolithic revolution, human beings began growing crops and keeping animals and they no-longer depended on gathering and hunting. Through raising animals and growing plants, they made bigger and more established food sources. The Neolithic Revolution took place in sub-Saharan Africa in 2,500 BC and Melanesia 10,000 years ago. This revolution changed the activities of hunters and gatherers who were prevalent in sedentary communities based-in urbanized towns and villages.
These societies improved their natural surrounding using various storage and cultivation technologies (e.g. irrigation) that brought extra production. The changes were the commencement of high population compactness, trading markets, composite labor diversification, centralized governance, political structures, and philosophies.
Second Agricultural Revolution
The second agricultural revolution took place between the “17th century and the end of the 19th century.” This revolution was about the developments, innovation, and techniques’ development in Great Britain and other bordering nations. This caused a substantial increase in agricultural yield and net productivity which in-turn supported remarkable population growth, freeing up a considerable percentage of the labor force, and in so doing powering the industrial Revolution (Barker, 42).
Harvesting, plants’ care, fertilization methods, and new production technologies were improved as well. Farmers acquired larger farms, fenced them, and began rotating fields. Production technologies included; seed drilling that simplified methods of rows’ planting and improvement in livestock breeding that made animals produce high-quality milk and beef. The Industrial Revolution played a significant role in sustaining the second Agricultural revolution.
Third Agricultural Revolution/Green Revolution
During the Green Revolution new agricultural methods were generated to assist farmers all over the globe. It was a global effort that was intended to eradicate hunger and food shortages by improving the performances of food crops. This plan brought about new methods and practices that enabled farmers to harvest more food within the same sizes of land. This meant that farmers produced more from their land than what they did before.
Green Revolution: positive and negative impacts
Green Revolution involved two major activities i.e. increase of fertilizers’ use and introduction of highly productive seeds. During this period, new practices were introduced to help farmers globally. This revolution existed since 1930 when Midwest agricultural specialists started controlling seed varieties to improve crop productivity. The green revolution was both succeeded and failed at the same time; the revolution had positive and negative results. This revolution prevented food emergencies in Latin America and Asia during the 1970s and 1980s. However, the revolution was not a successful tactic in ending global food shortage and hunger (McInerny, 59).
