It has is somewhat of a fashion among conservative thinkers to mark their defeat in America’s ‘culture wars’ by composing requiems for the classical education no longer taught at American universities. [1] When the lament turns to the study of history (as it invariably does), the eulogizer will raise two strains of melancholy, the first reporting the absence of even most basic historical knowledge among today’s university graduates and the second relating the sad eclipse of the field’s traditional focus on political, economic, and diplomatic history with the newer, less rigorous, and less relevant sub-fields like queer, gender, post-colonial, subaltern, and environmental history.

As an observer with conservative leanings I occasionally succumb to the temptation to don sack-cloth and wail in lamentation myself. The gist of the standard lament is true enough. As stated here I only regret the last sub-field’s inclusion in it. What environmental history shares with the other sub-fields listed is a popularity derived from progressive political concerns. The connection is unfortunate, for in most other ways these fields are—or at least, should be—completely different. The historian who sets out to study “Urban Culture and Transgender Sexualities in 18th Century Madrid,” for example, has committed him or herself to the intense examination of such a tiny and unrepresentative sliver of humanity as to make all of his or her conclusions useless for understanding the broader course of the human past. The same cannot be said for environmental history. There are few fields whose findings have such a clear and wide ranging impact on every other aspect of human civilization. The rise and fall of dynasties, the great deeds of armies and generals, the wealth and poverty of nations, and the daily life of men and women across human history were molded by the ecological setting in which they occurred.

A book I often recommend to those who doubt that environmental history is essential to making sense of human civilization is Alfred Crosby’s Ecological Imperialism: The Biological Expansion of Europe, 900-1900. Over the last three decades a torrent of books and articles have been written to explain why the West was able to rise above ‘the rest’ and establish global supremacy. While of the same vein as these works, the question that animates Ecological Imperialism is slightly different: why were Europeans so successful at reproducing European society (and completely displacing the previous inhabitants) of some locales but unable to accomplish this same feat in other locations? Why were white settlers in North America, New Zealand, Australia, Argentina, and South Africa fantastically more successful than their fellow colonists in Brazil, Mozambique, Panama, or New Guinea? 


The answer, says Crosby, is ecology. European expansion was not just a movement of peoples, but of entire environments. For settlers to survive and thrive they must be able to secure food, construct buildings, and move about from place to place. European civilization allowed Europeans to do this on a scale new to human history, but the successes of Western civilization cannot be separated from the environment from which they sprang. Its great cities, armies, and ships were ultimately built upon a unique suite of European flora and fauna. When transplanted far from their homeland these alien organisms do better in some lands than in others. Places where climate and local disease prove hostile to European biota, like central Africa, are places where Western imperialists could only establish an ephemeral presence. Places like Brazil or Mexico, less deadly to European life but unsuitable for large-scale colonization without adopting indigenous crops and farming techniques, produced creole cultures that mixed European and Amerindian traditions. In Australia, New Zealand, North America, and the South African coastline the only environmental constraint European settlers faced was distance. The geography, climate, and ecology of these places were perfect for European biota, allowing them to displace native life without conscious effort.





The displacement was complete and utter. American readers may be surprised to find out how much of America’s ‘natural and wild’ wilderness is made of European aliens of recent import. Sparrows, starlings, house flies, honeybees, garden snails, earthworms, common rats, white clovers, dandelions, Kentucky blue-grass, stinging nettles, knot-grass, broadleaf plantains, Bermuda grass, periwinkles, mayweed, ground ivy, knapweed, milk thistles and almost every type of grass you can find east of the Mississippi originated in Europe and came to the United States in the two centuries after 1650. And that is just a small sample of the hundreds of plants and animals that came to America along with the Europeans. What started as a few alien weeds accidentally carried across the sea grew to dominate entire ecosystems. By 1940 an ecological survey in Southern California could report that “63% of herbaceous vegetation in the grassland types, 66% in the woodland, and 54% in the chaparral” were naturalized plants. [2]

The expansion of European biota across the land was not simply a consequence of European migration. In most cases it was an essential precursor to large-scale European immigration itself. European colonization of New Zealand’s South Island is a case in point. The first settlers in New Zealand did not believe that sheep could ever prosper there, for both islands, being carpeted by ferns or covered with dense forest, had no grass to speak of and nothing sheep could survive on. Initial attempts to remedy the situation by introducing flowering plants to New Zealand failed. The plants would grow but could not reproduce: New Zealand had no insect species adapted to pollinate them! It was not until settlers brought honeybees to the islands that the situation changed, leading to an explosion of European plants across both islands. The new grasses and clovers were perfect feed for English sheep, and it was not long before the sheep had reached such numbers that they became one of New Zealand’s chief exports and an economic pull for more migrants. [3]

While Professor Crosby does not use this term, it should be clear to today’s readers that the European settlers, crops, livestock, weeds and grasses were all part of one interconnected system upon which the settler communities were built. The colonization of the Americas, Africa, Polynesia, and Australia should be seen as the evolution of one ecological system into another.

This conception of environmental history is far more useful than many narratives historians have come to rely on when writing on this topic. Environmental histories are generally of two types. One divides the Earth into a world of nature and the world of man, the second advancing at the expense of the first. This is the tale of cleared forests, extinct species, polluted waters, and the ever growing ‘footprint’ of humanity. [4] The second narrative is one of exploitation and collapse, positing that societies decay and collapse when they overuse the ecological resources available to them. [5] Both present a moral tale easily used to condemn 21st century man’s ruinous relationship with nature.

These two narratives have some truth to them, even though their arrangement reveals more about current political concerns than actual historical dynamics. A much greater weakness with these narratives is that it is difficult to fit the type of transformations and systems Crosby discusses into their confines. In many ways the models used by ecologists to describe the role of individual species in their ecological systems and the transitions these systems make from one state to another are better suited to describe human interactions with the broader environment than any of the traditional narratives are. Humans are far from the only species that “engineer the environment to make it suitable for [their own population] growth[6] and the basic models that describe the ecological dynamics of plankton, savanna grass, and rainforests should be studied just as closely by historians as documentary sources that reveal how past societies depicted or thought about their relationship with the environment.

This approach is not without its own difficulties. Perhaps the biggest problem is that ecologists themselves have developed few models that integrate the complexities of human energetics with their traditional field of study. As ecologists Erle Ellis and Navin Ramankutty note:
“More than 75% of Earth’s ice-free land showed evidence of alteration as a result of human residence and land use, with less than a quarter remaining as wildlands, supporting just 11% of terrestrial net primary production… [but] ecologists have long been known as the scientists who travel to uninhabited lands to do their work. As a result, our understanding of anthropogenic ecosystems remains poor when compared with the rich literature on “natural” ecosystems.” [7]

As time goes on we can only hope that more ecologists, geographers, environmental scientists, archaeologists, anthropologists, and historians work to provide the more nuanced understanding of human and environmental systems Ellis and Ramankutty advocate, one where we do not depict environmental history as the story of "natural systems, with humans disturbing them," but one of "human systems, with natural ecosystems embedded within them." [8]

Nice post.

I think there's an important element that you've overlooked: the fact that some historians try also to account for nature's impact on human life (as opposed to the reverse). I suspect that this God-fearing approach would sit well with a more conservative leaning crowd.

I've recently read two books that fitted this bill very well. W. Bulliet's Camel, Coton and Climate (2006) and R. Ellenblum's Collapse of the Eastern Mediterranean. They both charter the impact of the 11th century "big chill" in the Near East and they make for a compelling and truly amazing human story (yes, I'm a fan).

If you haven't read them I have but one word for you: enjoy!

@History Mill-

I thank you for both the kind words and the recommendations.


I tend to see the two as going along together. The environment constrains human agency, but human decisions change the "natural" environment. In many ways one could describe the history of civilization itself as an interplay between the two.

One of the most disappointing reads of this year was Felipe Fernandez-Armesto's Civilizations: Culture, Ambition, and the Transformation of Nature. The book was a erudite and stylish attempt to do just this, classifying societal systems by the ecology and geography they were built on. Unfortunately the book lacked empirical rigor. The premise was brilliant but the conclusions were lacking.

My wish is that someone with the mathematical bent and empirical bent of a human behavioral ecologist or a cliodynamist to take up Fernandez-Armesto's categories and subject them to real analysis.

Addendum on historical priorities

This post has caused a fair amount of discussion on places like twitter, other forums and websites across the web (e.g., like this one), and personal communication with the author. Most of this discussion has not been about the main message of this post, but the way I chose to introduce the topic in the post’s first two paragraphs. I really don’t have time to write up a formal treatise on the topic, but because of the controversy raised I figure it is best I clarify a few confused points. As these points are only indirectly related to the content of the main post I shall post this addendum in the comment feed instead of editing the body of the post itself.

1. This post was not intended to be a comprehensive treatise on environmental history or any other historical approach. In comparison to the real historical essays that occasionally appear at this site, it does not contain a vast bibliography or a nuanced discussion of every scholarly lens so far developed to examine the issue at hand. Stylistically it is most similar to posts like “A Few Stray Thoughts on World History and its Books” (Scholar’s Stage, 11 September 2013). Its role is to offer a few observations and thoughts to get people thinking about the topic in a way they usually do not—it is a conversation starter, not a conversation closer. In particular, it was intended to get conservative readers (who make up a majority of my readership) who might normally discount environmental history as environmentalist fluff to take the discipline and its findings more seriously.

2. Most of the controversy has centered on two quotes from the beginning paragraphs. These are:

”the second relating the sad eclipse of the field’s traditional focus on political, economic, and diplomatic history with the newer, less rigorous, and less relevant sub-fields like queer, gender, post-colonial, subaltern, and environmental history

And:

”The historian who sets out to study “Urban Culture and Transgender Sexualities in 18th Century Madrid,” for example, has committed him or herself to the intense examination of such a tiny and unrepresentative sliver of humanity as to make all of his or her conclusions useless for understanding the broader course of the human past. The same cannot be said for environmental history

More than a few people were offended by my declaration that some topics and historical approaches were of greater value and worth than others. As one twitterer asked, “[where do you get the] authority in deciding on what is & is not an "unrepresentative sliver of humanity”?

I believe the best way to approach that concern is with a concept essential to economics: opportunity cost. The discipline of economics posits that man is an animal with unlimited wants but limited means. He cannot have everything he wants, so he must prioritize and choose what he believes the best use of his money, time, and attention to be. Every action thus comes with an opportunity cost. The cost of choosing to do something is not simply the stated cost in dollars or hours, but all the benefits you may have received had those dollars and hours been spent somewhere else.

Scholarship is a human endeavor and it obeys the same economic laws as all other human activities. The decision to write a book, research an article, or pursue a graduate degree all come with an opportunity cost. In many cases the opportunity cost is quite high—to secure a PhD in the humanities requires tens of thousands of dollars in tuition and grants, five to seven years of intense work and research on part of the student, and thousands of hours of reading, mentoring, and critiquing on part of tenured professors. Our society pays a lot for every PhD it creates.

July 8, 2014 at 5:19 PM

This is true in the broad sense of the decision to begin a PhD (what could all of these extremely intelligent, ridiculously diligent, and mostly multilingual individuals be doing for our society if they were not locked away in libraries and graduate seminars?) but also with the more narrow decision of what topic should be studied. In a world without scarcity this would not matter. In such a world we would have multi-volume histories of every mountain height and every blade of grass and scholars could study away on whatever they wished, learning simply for learning’s sake. But that is not the world we live. In our world a history written on topic A is a history not written on topic B. We simply cannot have everything. We must prioritize.

And that means telling people some subjects are more important to study than others.

3. This does not just apply to disciplines closely connected to progressive identity politics. Let us look at a field that has a more traditional, ‘conservative’ bent: military and political history. There are too many scholars studying the conduct of America’s 20th century wars. Revisionists will always try to remake the past, but in many ways scholarship has exhausted topics like World War II. Now to write something truly groundbreaking about the Second World War you need ">master reams of economic data and novel forms of economic analysis or learn to read five languages and do archival research in each. The English speaking world would probably be better if just a fraction of the scholars writing on the Second World War were to change their focus to a less researched war-say, the Taiping Rebellion, which killed 20 million people before it was over. The marginal return on investment on such a research project is simply much, much higher. You can fit all of the English-language books on the Taiping Rebellion on a single bookshelf. Anything these historians would write would be groundbreaking simply because they wrote it.

4But back to the identity politics topics. This same opportunity cost-marginal utility perspective can be applied here. Resources should emphasize 1) where we have gaps in the literature 2) where filling the gaps will do the most to expand our knowledge of the human past.

I pick on Queer Studies because it is such a clear example of a field with a very narrow focus whose popularity would not be warranted were it not for modern political concerns. (Don’t believe me? A few questions to ponder: how many transgender individuals live in the United States? How many more Jehovah’s Witnesses are there? Google it and do the calculations. Why are there so few books and departments and journals devoted to “Jehovah’s Witness Studies”?)


Similar calculations are in play for the others. Some because of narrow focus of the topic (queer, gender*), others because of the narrowness of historical methods most commonly used to analyze the topic (post-colonialism, subaltern. Blame critical theory). But in all cases the marginal benefits of additional studies are small, and their results peripheral to broader historical concerns.

In setting priorities the axe must fall somewhere. I suggest it fall here.

*Gender History and Women’s History are not the same thing. See here and here and here, and here on the differences.



I tend not to emphasize women’s history as such, for in most situations I view it as a tad superfluous—seeing as woman comprise 50% of humankind, any social history that does not put women front and center fails a priori.



Readers might also notice that I did not include social history on the list. That is because there is overwhelming evidence that social history matters in all the ways I have discussed history mattering. Indeed, social history (and particularly family history) is a recurring theme on this blog. See the series Islamic Terrorism in Context for a good example.

July 8, 2014 at 5:33 PM

I think our thoughts are almost identical on the matter. Really, enough with the Second World War (despite my having just blogged about a very macro-view of US foreign policy which contains references to that war....)

What's the first book about the second world war ? the link does not work. And Fernandez-Armesto is extremely overrated.

July 10, 2014 at 11:56 AM

The first book is Adam Tooze's Wages of Destruction: Making and Breaking of the Nazi Economy.

Sometimes blogger's commenting system freaks out and corrupts half of my links. No idea why.

July 10, 2014 at 8:25 PM

I love that book (and I think you can imagine that to be true....) but I like even more his "Statistics and the German State" but one must be really hard-core to even want to read the latter...
