Britain and the Origins of the Industrial Revolution, Part 2: Population Growth and Improved Food Production

In Part 1 of our 7-part series on Britain and the origins of the Industrial Revolution, we introduced it as a time of gradual but fundamental change (transformation) in Britain from a dependency on organic resources and means of production to mechanized production using sources such as coal.  Along the way, Britain became more urbanized and expanded its markets domestically and internationally, becoming the world’s foremost power by the early to middle of the 19th century.  How did this happen?  What preconditions facilitated this transformation?   

Part 2 examines one of these preconditions: Improved Farming and Population Growth.

Improved farming and population growth provided essential preconditions for industrialization. Factory owners would need more people to grow their labour force and to buy their products.  More people required more food, and this growing demand hastened agricultural innovations that, in turn, facilitated population growth.  During the 17th century, farms gradually depended less on environmental whims and offered more predictable and productive yields.  Before these changes, people lived according to a traditional cycle of population and productivity.  When food production reached a limit based on available land and agricultural methods, the population reached a threshold, declined, and grew again until it reached production limits. This pattern stemmed from a system where agriculture involved subsistence for peasants and income for landlords and common lands were used for grazing livestock and fuel (e.g. wood).

Commercial Farming, Cash Crops and Enclosures

Various agricultural innovations drastically improved farm production and broke this cycle.  One fundamental change was the development of market-oriented agriculture. Landowners, mainly nobles, increasingly fenced off common lands to create land enclosures focused on growing cash crops for sale and export rather than local consumption. Governments, who sought noble support and tax revenues, supported these measures against peasant resistance – sometimes with armed forces.  This displaced peasants and many became wage earners on far or factories. 

Farmland enclosures

These cash crops created a greater demand for larger fields. Historian John Merriman writes, “Between 1750 and 1850 in Britain, 6 million acres – or one-fourth of the country’s cultivatable land – were incorporated into larger farms. (518)  The trend toward commercial agriculture was well on its way.

Farming Innovations: Crop Rotation and Animal Husbandry

As farming became more commercialized, farmers became more specialized and adopted practices such as crop rotation.  Crop rotation differed from conventional agriculture, which saw farmers plant the same crop in the same place every year while leaving some fields fallow for two or three years to replenish their nutrients. Problems arose as these crops drew the same nutrients out of the soil, thus depleting it. Moreover, pests and diseases could establish themselves more readily.  Crop rotation addressed these problems.  Planting different crops sequentially on the same land optimizes soil nutrients and helps prevent pests and weed infestations. For instance, a farmer might plant corn one season and beans the next.

Healthy soil and healthy crops drastically improved food production.  Innovators like Robert Bakewell (1725-1795) improved animal husbandry, enhancing food supplies – particularly protein. 

Technological Advances

Technological advances also increased productivity. Farmer Jethro Tull (1674-1741) created the seed drill that planted seeds in deep soil, a drastic improvement over simply casting seeds on or near the surface where they would be more vulnerable to the elements or animals. Iron plows allowed farmers to turn the soil more deeply.

Charles “Turnip” Townsend (1674-1738) learned how to cultivate sandy soil with fertilizer from the Dutch and expanded arable lands (Kagan 495).

More production and more food options.

Throughout the next century, these farming innovations meant fewer people could produce more food, and more food could be grown per acre.  Improved food production also created more varied and calorie-rich diets –fundamental contributors to population growth.  The potato and maize – two nutritious foods from the Americas played essential roles.  Imported from the Americas, the potato became especially widespread throughout Europe.  Donald Kagan writes, “On a single acre, a peasant family could grow enough potatoes for an entire year. (Kagan, 497).  These local developments were bolstered by what Alfred Crosby called the “Columbian Exchange” – the exchange of food, animals, and disease between Europe and the Americas—from this, Europe gained maize, potatoes, sweet potatoes, and cod.  Indentured servants and slaves – laboured to produce these essential foodstuffs. 

Overall, production rates soared. Merriman points out, “England produced almost three times more grain in the 1830s than the previous century.” (Merriman 518) Besides feeding more people, farms produced more fodder for livestock and helped create a more reliable milk and meat source. More livestock also meant more fertilizer (manure).  Fish like the cod harvested off Canada’s east coast offered another protein source. 

Nutrition, Sanitation and Disease

Better nutrition went hand in hand with improved disease prevention and treatment. Diseases like tuberculosis, influenza and dysentery still took many lives but conditions generally improved as cities gradually improved water supplies and waste management.  Medical practices only played a minor role until well into the 19th century. However, Edward Jenner’s vaccines for smallpox in the 1790s helped contain lethal outbreaks, and vaccinations would help stave off other diseases in the next century.

Rapid Population Growth

Over the eighteenth century the turn of the century, the population of England and Wales increased from about 5.5. million to approximately 10 million and 20.9 million by 1850.  (Cipolla, 29)   Growing numbers in urban centers like Manchester provided cheaper labour for factories to flourish.  Moreover, the combined factors of population growth and increased income per head led to more purchasing power and growing demand for products – – two essential factors for industrial growth.

Part 3: Access to Foreign Markets and Capital Investment

What was the “Agricultural Revolution”? 

Try this. Ask people to name three revolutions.  Depending on their background, they might cite the American and French Revolutions of the nineteenth century.  Others will mention the Russian Revolution of 1917 or the Industrial Revolution.  How many cited the Agricultural Revolution?  Likely not many.  Ironic, since the agricultural revolution stands as one of the more fundamental and far-reaching developments in human history.  Peter Stearns calls it a “great watershed in human history.” (Stearns 16) Ronald Wright argues that “In the magnitude of its consequences, no other invention rivals farming…”  (Wright, 45)

So, what is the agricultural revolution? When did it happen?  How did it change how humans lived? It is a far-reaching and complex topic but let’s try to cover the essentials.  “Essentially,” the agricultural revolution transitioned nomadic hunting-gathering societies to human societies that grew their food and for some domesticated animals.  This development is revolutionary because it fundamentally changed how people lived.  Hunting and gathering societies depended on edible wild plants and animals, whereas agricultural communities controlled and shaped their environment (to some extent) to grow crops and domesticate animals.  Besides planting crops, agricultural societies changed their landscapes through irrigation and canal construction.   

When Did it Happen? Where did it happen first? The above chronology offers a general timeline. Essentially we are looking at 9000 BCE to 3500 BCE.  Agriculture on a large scale first happened in various river valleys (e.g. Nile River, Indus Valley, Mesopotamia, Mesoamerica) that offered reliable water sources and fertile soil. Different crops grew throughout the world.  Egypt produced wheat and barley. People living on what became the Greek peninsula grew grapes and olives.  China cultivated rice

There are two points to remember.  One is that this revolution happened over a very long time – 1000s of years.   Secondly, agriculture occurred independently in various parts of the world and at different times. Mesoamerica, for instance, had no contact with Eurasia and alone learned to cultivate crops like maize and squash. Later, as populations grew and interacted more through trade, agricultural practices and technologies would be shared and accelerate agricultural production over larger areas. 

Nomadic to Sedentary and Permanent Dwellings.  Tending to crops requires people to stay in one area.  Hence the term “sedentary agriculture.”  Nomadic people might remain in one place for some time, but as soon as the supply of wild plants and or game ran low or migrated, they were on the move.   Permanent dwellings offered space to store food and house families.    

Growing Populations, Social and Political Specialization By increasing food production, the agricultural revolution also facilitated drastic population growth.  Agriculture could sustain more people in a smaller area.  As Greg Woolf writes, “5 square miles cold support a farming village of 150 people. (Woolf 58).  A more reliable food source also contributed to higher life expectancy.   These growing population centers became the first steps toward cities, city-states and even empires.  A food surplus allowed people to adopt more specialized roles in families, politics and religious life. 

What motivated hunters and gatherers to adopt agriculture?Great question.  After all, farming required more effort than hunting and gathering.  Accordingly, people likely adopted agriculture very gradually. Probably, circumstances pushed them in this direction.  Climate change, for example, might have encouraged big game to migrate north of the Middle East and other river valley areas.  Overhunting also might have significantly diminished the wild animal population.  Another factor might be growing populations that required alternative food supply offered by hunting and gathering.     

Historians, of course, differ on how the Agricultural Revolution came about, how it evolved and its impact.  Concerning the latter, some historians have lauded it as one of the seminal movements of human progress.  Others see it as the catalyst for current problems such as overpopulation, consumerism, rapid species extinction and climate change.  Whatever their position, they agree that the Agricultural Revolution is one of the most fundamental developments in human history.
