A prosperous way down – Principles and Policies - 2001
Howard T. Odum & Elisabeth C. Odum
University press of colorado
If you want a good introduction into topics like, how to change our ecological system, Emergy, the way to go in the future on the grand and little scale.You will learn a lot of new terms on the way like decession, turndown, Emergy and transformity. Go for this book, it’s all about principles and policies on the small, medium and grand scale.
Part I
The first one describes what the book is about, it’s not about less growth but decline. Then there’s a chapter called the present situation, it introduces a bit the views of our ecosystem, climate change from both sides and then it goes into fossil fuels. Then follows a very difficult but useful chapter on around 40-50 views of our present condition and the future (including Campbell, Hubbert, Cook, Thompson, Odum, Tainter, Diamond etc..) It gives a good sample of the books he mentions from all the different views. Soft Landers, Hard Landers, Doomers, Economists, Ecologists, Technofixers etc.. It gives you a good view of what situation we are in and the different views, there oughta be one in which we can identify ourselves
Part II
The second part is about the system principles. Chapter one tells us mainly about energy hierarchy and thus Emergy. Emergy is basicly energy converted into Solar Calories. This is done by looking at the transformity or the measure of energy going from one form to a more concentrated form. The definition of Emergy: Emergy is the available energy of one kind that has to be used up directly and indirectly to make a product of service. By doing this you get the whole ecological picture because when using EROEI you don’t calculate the costs involved in making the oil by the sun. Thus you don’t have the renewable picture of solar panels for instance. According to this calculation solar energy is a net loser when made with present oil guzzling industry. Wind energy is energy positive. You can also look it up in the EROEI tables at http://www.eroei.com. Chapter two describes the pulsing stages of society, growth, climax and transition, Descent, Low energy Restoration. Then there is a chapter about economy and how ecological influences should be added (Emergy). Well it’s all about net-Emergy. The next two chapters are about the organisation of our living space, how we should switch to a different form of input and output and the real problem namely population growth in combination with ecology and economy
Part III
The topic we have been waiting for, how to change our world.. It goes into the unequality of the world’s people, the prospects for renewable technologies based on Emergy calculations, How to sustain a nation, people were to start when going down the descent cliff. How to reorganise our cities, restore our waters. Get the landscape into a nice country again, what to focus on in trasmitting knowledge. And last but not least preparing people and a good summary. This all with very useful examples of principles and policies.
In basic it is quite a tough book to grasp, i definetly need to read it again soon because it is a very compact book with for me lots of new terms. Since i’m not into ecology which i think is a very important and interesting chapter. For instance he suggest to get a class called ecology, environment and economy on all schools. This is a must read i think if you want to learn about descent. Not really practical and it lacks the numbers in the third part but it gives you a very very good view on well... Principles & Policies ofcourse. And the chapter about the books and views is really useful for referencing and seeing how much books were just written in the past about the subject.
