This article is one of a series addressing globalization. Human history is discussed as four phases of progressively increasing social organisation (Natura, Agraria, Industria, Informatia) based on the form of energy used to drive social activity. Later articles give a brief account of the major world civilizations arising out of highly developed social organisation.


Informatia is a period category or phase of long-term history extending from about 1950 to the present.

Informatia reflects the synergistic integration of energy and increasing social organization (when there is greater social differentiation and complexity) to generate an acceleration in the growth of many aspects of human existence including: populations, economies, and collective learning. This includes a massive increase in not only the specialist knowledge of collective learning but the overall sum of information being generated, communicated, and stored.

Commercial, and indeed most social activity, is vastly enhanced by systems of writing (printing, digital communication) and counting. The efficiency of information communication depends on the degree of literacy and numeracy within a society, and the sophistication of the technologies of transport and communication.

We live in an age that is saturated with shared information.

Key distinguishing features

Key features distinguishing Informatia from the former phase of Industria include: the integration of the world into a close-knit global community as a new form of social organization; the implementation of a global energy transition from fossil fuels to renewable energies; a new phase of collective learning and communication as the universal democratization of knowledge for anyone with access to computers, smartphones, and the internet.

The historical phase referred to here as Informatia followed in the wake of the devastation and depression of two world wars, as economic recovery gathered pace around 1950 with globalization and technology taking a quantum leap in advanced industrial societies during the Great Acceleration. Increasingly sophisticated science and technology facilitated the more efficient extraction of planetary resources that unleashed unprecedented economic and population growth and complexification – the Great Acceleration – as the world population of 2.5 billion in 1950 soared to 6 billion in the year 2000.

The most obvious and far-reaching change in human plant use today is the modification of our energy dependencies as the world economy sets out on a transition from plant-based fossil fuels to renewable energy sources like wind, solar, biomass, nuclear and hydro and as, maybe for the first time in tens of thousands of years, average individual human energy use begins to plateau.

significantly, there was a 1200-year period from about 550 to 1750 CE during which the East scores higher than the West.


History may be reductively comprehended in terms of the social organization made possible by energy availability, capture, and use. What happened in historical fact depended on the mode of social organization and its consideration of what should be done (as determined by values and systems of governance); what could be done (as determined by the available resources influence of social scale); the rate at which it is done (as determined by the available technology).

Informatia is a electronic information society characterized by computers and smartphones. Social activity is increasingly powered by renewable energy rather than fossil fuels. Most people in the world now live in cities and humanity moves towards peak population of about 11 billion inhabitants between 2050 and 2100. This period is a post-industrial knowledge economy, with the service sector generating more wealth relative to the manufacturing sector in complex societies.Though there is a trend towards egalitarian and liberal-democratic institutions, traditional societies remain, and globalizing forces are countered by forces defending national sovereignty and regional self-sufficiency. There is resistance to gender differentiation and violence but acceptance of substantial wealth differences.


It had taken about 200,000 years for the human population to reach 1 billion around the year 1800 and then, fired by fossil fuel social energy, only 200 years more to reach 7 billion.

More people meant more urbanisation, upwards with the advent of skyscrapers and outwards as the expansion of houses and gardens into a sprawling suburbia. In 1800 about 3% of the world population lived in cities but by 2017 this had increased to 55% (Index Mundi World Demographic Profile 2018).

The post-1950s Great Acceleration is expected to reach peak population of about 11 billion people between 2050 and 2100 people, followed by a likely decline in numbers – which places an upper limit on humanities likely resource demands.


The expansion of Western cities during the Great Acceleration resulted in a new era of suburban living as commuter housing spread outwards from the commercial hubs. Horticulture was catering as never before with the new sprawling suburban blocks.

In 1900 London’s total population of 6.5 million exceeded the second-largest city, New York, by about 2.2 million. By 1950 New York’s population of 12.5 exceeded that of London (now the world’s second largest city) by 3.6 million. Today (2019) about 55% of people live in cities, a figure that is expected to reach 68% by 2050 (UN Department of Economic and Social Affairs). In 2015 the world’s largest cities were: Tokyo 37 million, Delhi 26 million and Shanghai 24 million reflecting the passage of economic activity to Asia reflecting the advent of the megalopolis as cities merge into continuous urban regions.


Socially perhaps the most obvious transition is from printed to digital communication. With the advent of computers and the internet the many forms of knowledge, once only available to the privileged few and therefore a form of social distinction, are now available to all who have access to computers or smartphones. The advent of the internet, smartphones, and social media has transformed communication and academic research as ever more information becomes available globally and instantaneously and collective learning expands at an unprecedented rate.

Computer-based electronic messaging is now global and instantaneous. A vast electronic economic and financial sector is replacing coins and notes. At the heart of the Information Revolution is wireless communications technology that links the world by internet, computers and smartphones. The first generation, or 1 G, was mobile voice calls. 2G brought text messaging. 3G addressed data and smartphones. 4G was optimised for accessing video. 5G adds super-fast speed and connectivity with data speeds 10 times that of 4G. It also gives access to millimetre wave spectrum which is a much higher frequency with data speeds more than 100 times faster than 4G.

Collective learning

The currency of this web site – its medium of exchange – is factual information. Factual knowledge is cumulative. Not only is there much more factual knowledge in the world today than yesterday – it better organized and can be accessed more rapidly by a wider range of the people, that is, its rate of accumulation is increasing. You have the potential to find out much more about the world than your parents could find out at the same age – because much more is now known, and it is more readily available.

The proliferation of academic disciplines that occurred in the 19th century now became a flood. Whole new areas of study were awakened by flagship publications: the environmental movement and environmental studies, especially ecology, with Rachel Carson’s Silent Spring (1962); media studies with Marshall ‘The Medium is the Message’ McLuhan’s Understanding Media: The Extensions of Man (1964); a plethora of new subjects in the field of microbiology were heralded by James Watson’s The Double Helix: A Personal Account of the Discovery of the Structure of DNA (1968); linguistics and cognitive science were opened up by the publications of Noam Chomsky in the 1960s and ‘70s. Alvin Toffler’s Future Shock (1970) outlined the characteristics of accelerated social change as characterized by transience and the commodification of many aspects of life: the disposability of mass-produced goods; increased renting rather than ownership; pervasiveness of advertising; more frequent changing jobs into new trades, professions, and places of work; relationships becoming more local, brief, and superficial. Garden history, which entered academia in the 1980s, had a line drawn under it with publications like The Oxford Companion to Gardens (1986) locally expanded with The Oxford Companion to Australian Gardens (2002) and then, several decades later, the six-volume A Cultural History of Gardens (2013).

World history arose as a response to narrow and inward-looking history of the West, and histories traditional time-frame, beginning with the written word, was extended to the history of the universe by Big History in the 1980s.


With the environmental movement of the 1960s came a new realization of human environmental impact at the global scale. There is now a broad scientific consensus that the impact of human activity on planet Earth warrants recognition through the naming of a post-Holocene epoch called the Anthropocene.


However, there is no universal agreement on the cut-off time for this new epoch. On this web site 1950 has been chosen for the many additional social and economic changes that occurred at around this time, the whole falling under the general rubric ‘Informatia’.

The following is a list of interrelated factors that have contributed to the Anthropocene:

Global biogeochemical cycles

The most striking demonstration of the global impact of human activity on the earth system is through its impact on the global cycling of chemicals chemicals crucial to life: water, carbon dioxide, oxygen, nitrogen, and phosphorus. The water cycle has been altered by human impact on vegetation, especially forests, and by the secondary effects of climate change resulting from the accumulation of anthropogenic carbon dioxide produced from fossil fuels. Global cycling of nitrogen and phosphorus has been altered by the widespread use of these chemicals for industrial agriculture, as fertilizers, pesticides and herbicides.

Global landscape change

More than 75% of Earth’s ice-free land area has now been significantly altered by human activity. Biogeography has traditionally referred to wild as biomes but human activity can no longer be ignored as biomes become anthromes. Swathes of once relatively pristine natural landscapes have been converted into cultural landscapes populated mostly by anthropogenic or ‘man-made’ plants (cultigens).

Nuclear fallout

World War II and the subsequent bout of nuclear testing has left a permanent planetary stratigraphic signature.

Primary productivity

With the population explosion more land was taken by the industrialized agriculture needed to provide food.

Human appropriation of plant net primary productivity (HANPP) is a metric that tracks the percentage of global net primary production that has been harnessed by humans for food and livestock production, and fuel: it includes the loss of potential NPP due to human land use and it is a benchmark indicator of human impact on the biosphere.

From 1910 to 2005 HANPP almost doubled from 13% to 25% while population grew 2.7 times and GDP grew about 17 times (Krausmann et al., 2013; Haberl et al., 2014). The increasing harvest from forests and the additional land occupied by infrastructure has added little to HANPP. It is agriculture that dominates HANPP globally, representing 84–86% of total appropriation of plant growth over the entire period, with 42–46% on cropland and 29–33% on grazing land.

We must also consider the global impact of plant-energy-dependent domesticated animals. The ‘MacCready explosion’ points out that 10,000 years ago humans, their pets and livestock, comprised around 0.1% of the terrestrial vertebrate biomass. Today this total has rocketed to 98% (MacCready 2004). Though a statistic that is difficult to substantiate, this is a stark reminder that beyond human demands for plant food and other resources are the demands on planetary ecosystems resulting from animal domestication.

Sixth mass extinction event

The Holocene’s Anthropocene epoch is the world’s sixth mass extinction event; its causes are anthropogenic. Evolutionary theory implied the natural extinction of poorly adapted species as environments changed over millennia influenced by natural events and processes like volcanoes, erosion, and sedimentation. Today we know that there is both gradual (background) extinction and sudden mass extinction as when the asteroid ending the Cretaceous period (fifth mass extinction) that wiped out 75% of all species. The disappearance of amphibians began in the 1980s but there was also reef-building corals, sharks, rays, fresh-water mollusks, reptiles, mammals, and birds. Anthropogenic global warming has changed the composition of the atmosphere by adding vast amounts of carbon dioxide which, since the Industrial Revolution, has risen by 40%, heating the planet, melting ice, and acidifying the oceans with carbonic acid, making them ~ 30% more acidic than they were in 1800. The pH is on track to fall to 7.8 (from today’s average of 8.1) by the end of this century, making the oceans 150 percent more acidic than before the industrial revolution. More than half the planet’s land surface consists of anthromes. Species spread by humans are no longer limited by geographic barriers and invasive species wreak economic and ecological damage.


Among the most notable areas of growth have been: human population and its consumption of energy and other resources, collective learning, technological innovation, urbanization, globalization, and economic activity.


Economically this period is sometimes referred to as the post-industrial information society or knowledge economy in which the service sector generates more wealth than the manufacturing sector.


Environmentally this time has been dubbed a new post-Holocene geological epoch, the Anthropocene.


The most obvious social change has been a Communication Revolution at first centred on personal computers, but now smartphones, the internet, and social media, in a major transition from hand-written and printed communication to the use of interconnected electronic media.


Most people in the world are now urbanites, living in cities that are attempting to transition from fossil fuel energy sources to renewables.

Informatia is best understood in the context of the three preceding phases of human history.

Politically we can associate Informatia with decolonization, the geopolitical dominance of America, and the formation of the United Nation, and latterly the rise of Asia, particularly China.

Popular writer Jamie Cawley, in The Birth of Now (2016) examines the historical path to today, noting that for 4000 years the Great Pyramid of Giza was the largest building in the world but that, between 1870 and 2010, more than 10,000 taller buildings were constructed. Up until 1889 the 100 tallest buildings (except the pyramid) were churches in Europe. From 1930 to 1998 the tallest buildings were in the USA and all were commercial. Today the tallest building, and about 60 0f the tallest 100, are in Asia. Tall buildings themselves are of little interest but these figures indicate major global transitions in the distribution of technology, power, and authority over the last 150 years.

Science & technology

The onset of Informatia was pre-dated but heralded by the publication of the General Theory of Relativity in 1915, and the emergence of Quantum Mechanics, which coalesced into a coherent theory around 1930.

Post 1950s scientific research has, on the one hand, extended the scale of investigation into the atomic and molecular and, on the other, into the global . . . and beyond into distant space. The explosion of atomic bombs in 1945 and the cracking of the genetic code in 1952 marked the start of new eras of particle physics, molecular biology, and biotechnology. The Human Genome Project was completed in 2003. On the other hand the environmental movement of the 1960s launched studies into the global environment and ecology, all firmly grounded in evolutionary biology. Gaps in the evolutionary record continued to be filled relating to birds, dinosaurs, the transition from water to land, and the significance of extremophiles. This spawned many new subject areas including conservation biology, environmental history and other disciplines. Space travel crossed the boundary of the solar system.

Accelerated by materials research for WWII, by the 1960s various forms of plastic were now being used in the home, while the quantities, kinds and global distribution of synthetic chemicals has escalated along with the influence of agricultural chemicals including herbicides and fertilizers, the latter to a degree that affects the biogeochemical cycling of nitrogen and phosphorus.

The rapid advance of biotechnology and genetic engineering put humanity in a totally new relationship with nature, and its human manipulation. A Chronometric Revolution over the last few decades has brought science within the traditional domain of history, allowing us to date the age of the universe, individual rocks and fossils, archaeological remains, and the divergence of lineages in biological evolution.

Among the landmark discoveries and innovations were C14 dating (1946), TV (1950), the birth control pill (1950), optical fibre (1956), satellites (1957), silicon chip and laser (1958), colour TV (1960), space travel to the moon (1969). genetic engineering (1973), personal computers (1980), World Wide Web (1990), Wikipedia (2001), completion of the Human Genome Project (2003), social media (2004), smart phones (2007).

Science is now penetrating the last major scientific frontier – the human mind, consciousness, mental computation, and artificial intelligence. Humans are now custodians of both planet Earth and their own evolution.

Technological innovation in Informatia is sometimes referred to as the Third and Fourth Industrial Revolutions (IRs).

The Third IR is the post-1950s introduction of semi-conductors, PCs, and the internet.

The Fourth IR[2] is distinguished by technology that combines physical and digital technologies with biological systems. This includes genomics and gene editing, robotics, self-drive vehicles, voice- and face-recognition, artificial intelligence (AI) and rapid advances in neuroscience with other disciplines related to the brain, and 3-D printers for bionic limbs.

The period is also characterized by the acceleration in rate of technology uptake at the global scale.

Concerns relate to issues of inequality and privacy.


Economically we have entered what is sometimes referred to as the post-industrial information society, or knowledge economy, in which the service sector generates more wealth than the manufacturing sector.

This is a period of rapid post-World War II growth as economic activity gathers momentum into the Great Acceleration. Between 1950 and 2000 the global economy grew by a factor of 10, energy use increased 13-14 times, and use of freshwater increased nine times. 


The role of plants in recent technological development has become more subtle as each new technology modifies and supplements what went before. The Industrial Revolution (c. 1760 to c. 1840) is a phase characterized by the use of coal-fired steam engines, most notably in the textile industry. Between c. 1870 and c. 1914 major changes occurred with the investigation of oil products including kerosene and gas but quickly outdated by the introduction of the use of electricity and electrical lighting, steel production, and accelerated industrialisation. After 1914 petroleum became important with the introduction of cars, the manufacture of steel, and mass-production followed by the introduction of electricity that would, in the 21st century superimpose information technology on existing systems until today we are entering a new period of intelligent software.

Disenchantment with traditional politics expressed through protest votes for Briain to leave the European Union (Brexit) and for a reality TV American President (Donald Trump) have suggested new consensus values that are not based on ideology, either the old ideologies of capitalism vs communism, or new ideologies of government-controlled health and education vs Neoliberal private enterprise and the freedom of the individual and markets – but on a worldview whose primary emphasis is not on growth but the collective attempt to meet everyone’s basic needs by maximizing wellbeing, and living within planetary means.

Key points

The period referred to here as Informatia has been given many names depending on perspective – and including ‘The Great Acceleration’, ‘The Post-industrial Society’, ‘The Communications Revolution’, ‘The Information Society’, and ‘The Anthropocene’.

During Informatia there is a marked sense of global progress, manifest as undisputed advances in science, medicine, technology, literacy, and collective learning. The synergistic effect of this has accelerated the global pace of life. In general, global poverty is being reduced, life expectancy is increasing, more people are being better educated, and societies are becoming more equitable and democratic. A key characteristic of this activity is growth . . . in human population, consumption, and economic activity. Rapid improvement in communication and transport has resulted in an increase in global homogenization, of biota, people, culture, and institutions, one obvious example being the popularity of international cuisine.

The following are the major defining features:

EEA: mostly urban

Communication: verbal+written+printed+global, instantaneous, and electronic

Lasts: ?

Energy source & use: animal and plant food (increasingly synthetic) with complex social activity maintained by renewable energy and consumption remaining >200,000 kcal/capita/day

Group size: Global
World population: peaking at c. 11 billion around 2050-2100

Diet: mixed diet of animals, plants and processed foods but returning to plant-based foods

Values: trend towards egalitarian and democratic institutions as a tension between authoritarian (traditional) and emancipative values. Today, with most of the world’s people living in cities, we are suspicious of political and gender hierarchies and resist violence, but accept some wealth differentiation

Ecological impact: High rate of species extinction: humans impacting noticeably on global biogeochemical cycles from around the 1950s at onset of the Great Acceleration (Anthropocene) Great Acceleration; high rate of species extinction: humans impacting noticeably on global biogeochemical cycles (Anthropocene); nuclear footprint
