How to connect to the cycles and achieve intelligent systems


After taking a look at how natural systems are different from the industry of yesterday and today, we will now take a look at three areas that are connected to meeting our basic needs. In each of them it is actually not difficult to become sustainable - theoretically. The water is moving in a big cycle as we already learned as school children. The sun provides more energy than we can possibly need and there are still other renewable sources (geothermal, tidal, water and biomass - the last two also powered by the sun). And food eternally grows on the fields if only we plant, look after and harvest it. The practical issues we have to deal with when trying to get a sustainable supply of water, food and energy are the topic of this week. I will not give you long readings, because you will have to do quite some research into your local water, food and energy situation (as you can see from the questions). So take your time to find out what is happening in your community and country.

Further ideas and materials for self-study

Water

Sustainable solutions to the water crisis:

  • water-saving techniques, reuse, eco-sanitation, restoring of forests, SODIS (for quantity)
  • eco-sanitation, industry (for pollution)
  • economic/public policies, no to privatization (for access)

general

ecological sanitation

access to water

  • World Bank vision on the topic of Access to Safe Water - Bolivia case - There are exercises together with this case study. Please try them out. How do you like this way of working online? How does it compare to our course?

saving water

  • "Sustainable Washing" - A site dedicated entirely to promoting water- and energy-conserving washing behaviour. You can calculate online how much time, water, energy and money you spend every year for washing clothes and dishes.

Food

Sustainable solutions to the food crisis:

  • promoting labor-intensive, organic agriculture
  • permaculture
  • food sovereignty before free trade
  • maintaining crop diversity


  • Agriculture - A small collection of facts and concepts about the extremely vast and important topic.
  • The Meatrix - about industrial meat production and its alternatives
  • Foodwatch (a German NGO)

Energy

Sustainable solutions to the energy crisis:

  • energy efficiency
  • low-tech plus high-tech decentralized renewable energies
  • including externalities of fossil fuels in accounting of prices
  • consumer-driven green electricity

renewables in general

  • Practical Action - a good website for exploring the various uses of renewable energy in the South for poverty alleviation. Based on the work of E.F. Schumacher.

strategies

  • The Energy Blueprint by Greenpeace and the European Renewable Energy Council - a hopeful scenario on our energy future
  • Energy Security (video 6 min) - Caroline Lucas talks about the energy options confronting us. She discusses her preference for clean renewable energy and why she thinks nuclear power has little future. She remarks on the many win-win policies that could precipitate a rapid shift towards efficient and sustainable energy supply, but acknowledges a lack in the political will required to bring this change about. She talks about the new production and consumption patterns that need to be encouraged, expressing doubt that economic growth can be sustained globally at 3% per annum.

decentralization

energy efficiency

  • Factor 4 asserts that energy efficiency is good for the environment and for business profits
  • Save energy when cooking with a cooking box

oil

  • Nigeria and Oil: one of the worst examples of poor corporate citizenship by oil companies operating in the South
  • The Future of Oil (video 6 min) - Dr. Campbell discusses the decline of global oil and gas production and talks about the likely impacts oil depletion will have on geopolitics. He addresses some of the solutions that may help defuse the situation. Advances in energy efficiency, in particular, offer many opportunities to this effect. He then talks about renewable systems such as wind turbines and tidal power and ends by suggesting what the individual can do to help accelerate the transition to energy sustainability.
  • Peak Oil: Next Steps (video 6 min) - Matt Simmons reflects on the reasons why the world consumes 85 million barrels of oil a day and points to ways to reduce fossil fuel consumption over time. First and foremost, we must alter the way in which people and goods are transported. We can do this by encouraging workers to commute less and by disincentivising long distance trucking. Next we must re-localize our food economy. Finally, he says, we must radically change the way the global economic system has been built.

biomass

  • Bioenergy in China (powerpoint presentation) (Question: If you compare this to Helmut Burkhardt's view, what would you say about this option in China?)

dams

green electricity
