Agricultural revolutions

Agricultural Revolutions in India marked the beginning of a completely new era in various socio-economic fields like agriculture, petroleum etc. Aquaculture refers to all forms of active culturing of aquatic animals and plants, occurring in marine, brackish, or fresh waters.

Agricultural revolutions

Covered in multimedia lecture Until this century, the vast majority of people spent their lives involved in one basic occupation: When these people could produce a surplus, they were freed to do other things, which provided the basis for towns, cities, and civilization.

Without the ability to produce surplus food, no civilization would be able to survive. Therefore, it should come as no surprise that the first step in building a new civilization in Western Europe was developing ways for Agricultural revolutions a surplus of food.

Before discussing these new agricultural techniques, it is useful to look at the state of Medieval life and agriculture in the Early Middle Ages. The vast majority of peasants were serfs, bound to the soil and service of a lord who owed them protection in return for work in his fields.

These serfs lived in villages, isolated pockets of farmland in the midst of a vast wilderness of forests, thickets, and marshes. Typically, a village would have several acres of cultivated fields, a wooden castle or manor house for the lord, a peasant village, a parish church, and a mill.

A village might be equivalent to a manor, the economic unit given to support a noble. However, it could just as well be divided into several manors to support several nobles or be only one of several villages making up a large manor. The village had to be self-sufficient because it was virtually cut off from the outside world.

Roads were poor and brigands Agricultural revolutions local lords constantly threatened travel. Raids from neighboring nobles and such invaders as the Vikings, Magyars, and Moslems also kept most people huddled under the safety of their lord's castle walls.

As a result, the flow of trade and commerce was reduced to a fraction of what it had been during the Pax Romana. Compared to the thriving Byzantine and Islamic cultures to the south and east, Western Europe was a fragile outpost on the western fringe of civilization.

The plow used then was still the scratch plow that worked fine in the thin dry soils of the Mediterranean, but was not very suitable for the wetter, deeper soils of Northern Europe. Such a plow might be reinforced with iron, or it might be nothing more than a curved digging stick. The main source of power for pulling the plow was the ox hooked up by a yoke harness that pulled at the neck.

Although slow, the ox was more than some peasants could afford. As a result, they had to pull their own plows or dig with spades known as delving. Finally, the peasants used the two-field system, where one field lay fallow to reclaim the soil's nutrients while the other field was being cultivated.

This left only fifty percent of the farmland for use in any given year. As a result, crop yields were very low. In the Roman Empire, for every bushel of seed grain planted, four bushels would be harvested. In the Early Middle Ages with the poor techniques being used, this ratio dropped to one and a half or two to one.

In other words, a full half or more of a peasant's harvest had to be saved as seed grain for next year's planting. In years of famine, this led to serious difficulties. Given these limits, it should come as no surprise that population remained low and grew at a very slow rate, if at all.

One has to be very careful when generalizing about what techniques were used where. This is because we have little evidence to go on, especially concerning the peasants, whose lives were of little concern to the monks writing religious histories. Also, the poor communications between manors meant that widely different techniques and tools might be used in a fairly local area.

However, it does seem likely that the light scratch plow, oxen, yoke harness, and two-field system were in general use in Western Europe in the Early Middle Ages. Then came some changes that would lay the foundations for more advanced civilization. First stirrings of revival It is impossible to say when population first started expanding in Western Europe, although we can make some educated guesses.

For one thing, the climate seems to have turned warmer in the 's. We base this on tree ring evidence and the fact that the Vikings could sail in northern latitudes unobstructed by ice.

The warmer climate meant longer growing seasons, better harvests, and thus a healthier and growing population. Major plagues that had hit intermittently since the later Roman Empire also ceased after C. This might be partly a result of the better-fed population having more resistance to disease.Study 66 Chapter 8 Quiz flashcards from Zola P.
