Post-Growth, Credit, Interest and Money

As impressively (though unwittingly) shown by Francis Fukuyama, attempts to imagine the future of societies are likely to go wrong. Extrapolation of trends can well be a bad idea. On the other hand, some idea about what the future is to look like is needed when a major transformation of the society is to be attempted. The transformation towards a post-growth society is no exception here. It would be naive to expect an exacting outline of how a post-growth society is supposed to work, but it is important that those advocating it at least try to give answers to some inconvenient questions: what about productivity growth? Can universal basic income, supported by many in the degrowth movement, work? And what about the monetary and financial systems? The latter question has gained some attention recently, and some argue that monetary factors might be a main obstacle for a post-growth society. Their arguments should get proper consideration if we do not want to choose the wrong transition “trajectory”, given path dependencies so common in socio-economic systems. Continue reading

What Do We Need Homo Oeconomicus For?

A few days ago, the celebrity among German economists, Hans Werner Sinn, published a short piece in the Süddeutsche Zeitung in which he defends economics against common and, according to him, mistaken criticisms. I won’t take issue with all 6 points he raised (invisible hand, ecology vs economics, Keynesianism vs neoclassical economics, competition, neoliberalism and homo oeconomicus), instead focusing on the last one. I had started writing a post on this anyway, so Sinn’s commentary comes just-in-time. The main question behind my criticism of Sinn’s presentation of the problem is: what do we need homo oeconomicus for? Continue reading

Anthropocentrism and Nature Conservation

In the environmental debate the claim can be often heard that granting nature intrinsic value would solve our problems – in other words, the difficulties we have with protecting nature are due to our overly human-centred perspective. Instead of invoking anthropocentrism one should, so the argument goes, move towards some sort of physiocentrism, i.e., grant some non-human entities intrinsic value. According to this view, anthropocentrism necessarily leads to destruction of the natural world. It is pathocentrism or biocentrism or ecocentrism or holism that would “save the world”. I already once showed that anthropocentrism is not as bad as claimed by those self-proclaimed physiocentrists. Today I would like to go further and show that meaningful conservation of nature is not compatible with physiocentrism – i.e., physiocentrism cannot consistently justify attempts to protect the natural world.

Sustainability Science is Puzzling.


Sustainability science can be fun, too.

First a warning: If you like your blog entries, insightful, well-structured and written with concision and clarity, you may wish to stop reading at this point (there are many other entries by Joern and others on this blog that can satisfy those peculiar cravings). If on the other hand you enjoy a somewhat rambling blog entry, that uses tenuous analogies, stretched to breaking point, then read on dear reader, read on.


When I say sustainability science is puzzling, I don’t mean that it is literally bewildering, bamboozling or baffling, although it certainly can be, rather, I mean it is figuratively like the act of ‘puzzling’, more specifically jigsaw puzzling (apologies for using puzzle as a verb, but when in Germany do as the Germans do).

Our world (bless its little cotton socks) is a complex, confusing and often chaotic place. To make sense of that complexity we have developed science…

Being policy-relevant vs. asking uncomfortable questions


Another very interesting post by Jörn Fischer.

Many scientists working on sustainability issues are in this business because they are concerned about the state of the world. It seems self-evidently reasonable that, therefore, we ought to try to use our science to improve the state of things.

Most scientists, when they think of being relevant, or changing the state of the world for the better, automatically think of informing or influencing policy. This can be a very useful way to change things for the better. For example, new protected areas have been declared on the basis of scientific input to policy; and restoration activities in degraded landscapes have been improved by scientific input delivered to government and non-government organisations. Seeking to inform policy therefore can be a useful activity for scientists trying to improve the world.

When looking at my own work, some of it has been policy-relevant, but some has not – but…

In Defence of Neobiota

As essentially an anthropocentrist I am entirely comfortable with the notions of useful and harmful species (which correspond with ecosystem services and disservices, respectively). However, I fiercely oppose the notion of “(invasive) alien” species, which is quite popular in the conservation discourse. Notwithstanding its obvious popularity, I think that it is flawed in being xenophobic and arbitrary. Continue reading

Ecosystem Disservices Revisited

Some months ago, I wrote a post here about the concept of ecosystem disservices. My conclusion was the following:

Ecosystem services are of tremendous importance and benefit to humanity. But, seen from the human perspective, these same ecosystems also generate disservices. This is something that is not accounted for in economic valuation efforts going by the name of “ecosystem services valuation”. However, it should be. If we count all the positive services Nature provides us with, we should be realistic and honest enough to count the numerous disservices against them.

Recently, however, I engaged in a discussion of this concept (under this blog post by Joern Fischer), which made clear to me that the matter is much more complicated than I initially thought. I would like to reflect on that point a bit today. Continue reading
