The Ecological Connection

In preparation for this blog post I had to do a little bit of hunting around, in order to try and understand the debate regarding climate as a factor to the fall of civilizations. Though to be honest, I couldn’t find much, if anything regarding an arbitrary proved or disproved debate. Instead I stumbled across a debate which encompassed the topic in the form of ecological principals, rather that the civilization is a living entity and thus can be defined and modelled around those ideas.

The birth of this idea dates back to the 1920’s, with scientists interpreting these societies as organisms which are born, developed and eventually withers away, often directed and led by creative individuals (Splenger 1926). Thinking in this kind of context it reminds me of playing Sid Mires Civilization V. I founded my little civilization and I developed and shaped it how I saw fit for that gaming experience. I ensured that its growth and economy was strong so that it could survive and progress. Though some ideas were haphazard and in retrospect led to my civilization becoming stagnant, falling apart and rebelling. 

Though the game is impressive in referencing back to West’s organism principal, it also highlights that the principal is not all that sound. Mainly that it neglects to account for internal and external systems which promotes the civilization grow and become sustainable (Butzer 1984). No longer viewed in isolation, but as a response to bring itself in equilibrium with its unique surroundings, this often increases the ‘social complexity’ of the civilization. Now that term might confuse some people, but the best way to explain it is in terms of an ecological concept, trophic levels.

Different Trophic level complexity

The more systems you have in place, the more people you need to run and mange those systems, and depending on the importance of said system will dictate where you are in terms of the trophic levels (Butzer 1980c). For example agriculture will be the base of the civilization, whilst the ruler and his advisors are at the top, dictating and affecting what’s below. The greater the complexity, the more resilient the system becomes to any changes which threaten to alter the status quo (deMenocal 2000).

So in essence the civilization is an opportunistic human ecosystem, but if that’s the case since climate ultimately controls the composition of an ecosystem, hasn’t climate got a very important role to play in the fate of the civilization?

Well the answer is yes, and no because these societies aren’t natural, they are human constructs and so even though they might show aspects of ecological principals, it doesn’t mean that it is going to react and behave like a system free from powerful intrinsic systems (Coombs and Barber 2005). Where am I going with this you might think? Well I’m going to go into more detail in my next post but I will give you a hint. Social Complexity.

Is that the factor which determines if your civilization can stand the test of time?
