Understanding and Planning A Prosperous Way Down Howard T. Odum and Elisabeth C. Odum Presentation by Thomas Abel Our Futures Now is a time of: Large world populations Stress on many ecosystems Economic problems Growing social inequality What will our futures look like? Our Futures Some think our economies can grow forever, that any limits will be overcome by technology – Techno-optimists Others predict the collapse of nature and economies – Dystopians Two extremes Techno-optimists Dystopia Our Futures But maybe there is path in between the two extremes A way that recognizes the importance of ecosystems and the limits to resources A way that offers hope that we can maintain the health and dignity of people, and the essences of life that are meaningful to us… …a prosperous way down A Prosperous Way Down Growth, transition, and descent If the principles and predictions within A Prosperous Way Down are correct, the world has no choice, nor should it fear the inevitable course in the latest chapter of our human journey Pulsing and Maximum Empower Pulsing From the study of ecosystems and other systems, the Odum’s argue that “pulsing”, as they call it, has four common stages Growth Transition Descent Low Energy Restoration Pulsing and Maximum Empower This is thought to be the course taken by all systems of nature, nested one within the other, constructed from both the living and non-living Pulsing and Maximum Empower The Odum’s have argued the ubiquity of pulsing to be the result of the selforganization of energy in systems, what they call the ‘maximum empower principle’ A nested hierarchy of pulsing patterns Pulsing and Maximum Empower A similar pulsing pattern has been proposed by C.S. Holling, called the ‘adaptive cycle’ The ‘Adaptive Cycle’ Pulsing and Maximum Empower Studies of many kinds of systems in many fields of knowledge show that pulsing is usual A time of gradual production and storing of reserves is followed by a short period of intensive consumption and recycling Pulsing and Maximum Empower Think of a shoe factory When a pair of shoes is made, it is not shipped immediately to the retail store That would be inefficient Instead, managers wait until they have made another pair, and another pair, and another pair Finally, at some point when the storage of shoes is large enough they are all shipped to the store for sale Shipping the shoes is the rapid consumption pulse Now the factory will slowly rebuild its storage of shoes Pulsing and Maximum Empower The traditional view in ecology and one model for our economic future is growth followed by leveling off into a steady state where inflows balance losses It is popular with many in our society who seek “sustainability” for our civilization “Sustainability” Pulsing and Maximum Empower Pulsing, however, prevails because operations that pulse transform more energy than those at steady state Apparently, an alternation of production and consumption provides a better long-run coupling of energy intake for maximum empower than a steady state can provide Pulsing prevails Steady-state leveling for ‘sustainability’ Pulsing and Maximum Empower Pulsing patterns result from selforganization A pulsing system of some form appears to be the stable one in the long run, repeating its periods of storage and use There are optimum frequencies for maximum performance Pulsing and Maximum Empower Over a long, long time fossil fuels have been stored in the Earth We are now participating in the consuming pulse Pulsing Systems Diagram Blue - Nonrenewable Energy Red - World Assets Pulsing Simulation Pulsing and Maximum Empower One of many examples of Hubbert Peak predictions Campbell (2004) Pulsing and Maximum Empower This presentation will explore the issues of energy resources, economy, culture, information, policy, and their relation to this pulsing model and its implications for our global future Our exploration will be speculative (nobody can see the future) But our exploration will alert you to new challenges that we may all face, and hopefully suggest valuable new solutions The State of the World Today Growth Becomes Transition The Global Network Chapter 9 The Global Scale and the Global Network As the growth melee strips the remaining natural capital of the Earth and civilization reaches its zenith… …the exclusive dominance of largescale capitalism can be replaced with an emphasis on cooperation with the environment and among nations Increased efficiencies are likely to limit extremes in the distribution of real wealth International trade and loans can be made equitable with emergy evaluations The Global Scale and the Global Network A major change in mechanisms for international order is evolving that can replace the old system of territorial defenses with shared military forces A reverse arms race may occur, with reductions leading to further reductions Territorial defenses Peacekeepers Disarming The Global Scale and the Global Network Global sharing of information and increased trade are joining the centers of civilization in common enterprise Already something of a new global culture is developing with the power to eliminate wars by interconnected futures and shared aspirations and attitudes for peace Shared information for common goals The Global Scale and the Global Network Examples of important shared information messages: Protecting the purity of the global atmosphere Maintaining cordiality and trade between neighboring countries that are culturally different Sharing technologies that are useful anywhere Protect our atmosphere Share technologies Biogas generator Maintain cordial trade relations The Global Scale and the Global Network Declining resources diminish nations’ inclinations and military capacities to encroach on others Providing that the remaining fuel resources are shared in open markets, great wars of national competition, growth, and conquest may never come again Small conflicts and boundary disputes may be within the power of international organizations to limit United Nations The Global Scale and the Global Network For a peaceful transition we need to: Share information internationally rather than sell it Arrange trade and loans with emergybased equity Replace resource exploitation with environmental mutualism Share Information Emergy-based trade equity Environmental mutualism Energy Sources Chapter 10 Evaluating Energy Sources Are there energy limits to growth? Is energy a substitutable commodity just like any other? Evaluating Energy Sources The value of an energy source is not in its yield Yield = energy out (J, Kcal, BTUs, etc) When evaluating and comparing energy sources, the important issue is always the net output Net is Y/F Crude oil, coal, natural gas Evaluating Energy Sources To get energy output you must do work – equipment, mining, pumping, transporting, storing, refining, research, new technologies, labor, educating technicians and researchers, etc. Net measurements compare the output against the input Fuels must have a net emergy output significantly greater than 1 to drive an economy Evaluating Energy Sources Although many energy alternatives and substitutions are possible… Energy Sources Evaluating Energy Sources … none in sight now have the quantity and quality to substitute for the rich fossil fuels that support the high levels of structure and Electricity Production process of our current civilization Coal-fired Power Plant Evaluating Energy Sources Burning Fuel for Heat (many uses) Emergy Yield Ratio Palm Oil Plantation Wood Natural gas, offshore Oil, Mideast Coal, Wyoming Oil, Alaska 1.06 2.1 6.8 8.4 10.5 11.1 Evaluating Energy Sources Making Electricity Emergy Yield Ratio Solar cell Wind power Coal power plant Nuclear power Hydroelectricity Geothermal 0.41 2-? 2.5 4.5 10 13 Evaluating Energy Sources Whereas ecosystems, forests, agricultural systems, and fisheries using sunlight have net emergy yields to support society, solar technology does not because the dilute nature of sunlight prevents efficient conversion directly to mechanical or electrical energy Sunlight is a dilute source Net emergy yield is 0.41 Evaluating Energy Sources The trend of substitution of one fuel for another continues toward more use of natural gas, but proven fuel reserves are not increasing Liquid Natural Gas Evaluating Energy Sources Because 71% of the whole Earth empower comes from fossil fuels, global consumption eventually has to be reduced to less than one-third of its current level Eventually we must live on one-third the emergy Evaluating Energy Sources For developed nations the impact will be greater They depend on nonrenewable resources for 80-90% of their energy They will eventually have to reduce either their populations or their living standard (emergy use) by 8090%. Evaluating Energy Sources However, with reduced populations we can look forward to a new but smaller agrarian economy, green again, enriched with knowledge developed in the fuel-rich century of complexity Transition Transition As we pass through ‘transition’, how do we… Sustain nations? Sustain people? Sustaining a Nation Chapter 11 Sustaining a Nation during Transition To extend the summit we need to sustain inputs (national emergy budget) and waste it less We need incentives to encourage favorable balances of international exchange and energy conservation Sustaining a Nation during Transition Cooperation in climax ecosystems Ecosystem analogies suggest good national policy Except in early stages of colonization, cooperation among units maximizes empower Keeping the climate stable helps sustain the economy Ecosystem Engineers Sustaining a Nation during Transition Cooperation in climax ecosystems Making trading partners prosperous assures continued jobs at home Sharing military expenditures reduces the costs of defense for each nation Mutualism Sustaining a Nation during Transition National energy policy Nations should maintain access to those primary fuel sources with the highest emergy yield ratios Sustaining a Nation during Transition Trade policy Nations should seek to maintain a positive emergy exchange With a positive emergy trade balance, nations can maintain what is essential in their way of life for some time Sustaining a Nation during Transition Trade policy For equitable trade between any two nations, all exchanges should be balanced (except fuel imports) with treaties for emergy equity Sustaining a Nation during Transition Trade policy Only fuel exporters should receive a negative emergy exchange, but due to their fortune in fuels they should easily sustain a high standard of living by using a sufficient portion of fuel for their own domestic development Dubai Sustaining a Nation during Transition Trade policy All countries should limit exports of raw products, and use them within their country Countries that sell raw products almost always receive less emergy in international trade than is embodied in the product Exports of real wealth Sustaining a Nation during Transition Domestic resource use Resource use at home lowers prices of food, housing, paper, and fuel within a country and raises the standard of living Less energy goes for transportation Sustaining a Nation during Transition Positive emergy trade balance is aided by: Energy conservation, especially by eliminating wasted emergy of cars and fuel Trade treaties that moderate inequities of free trade Military costs that are shared more widely Sustaining a Nation during Transition Fuel should be made available globally in markets Importing fuels is good for any economy Policy should not discourage fuel imports At current prices, an economy receives more economic stimulation from fuels than it pays out Taxes on productive use of fuels dampen an economy Using fuels for unproductive activity is a waste Sustaining a Nation during Transition New policies should emphasize: Information innovation Efficiency rather than speed Cooperation rather than competition Diversity rather than conformity Good maintenance rather than growth Suppression of borrowing Sustaining a Nation during Transition Security for nations and individuals can be sustained by replacing luxury and waste Sustaining People Chapter 12 Sustaining People during Transition To sustain people during transition, we will need: New levels of efficiency A ceiling on personal income (maximum wage) Public works programs at a living minimum wage Sustaining People during Transition We will need: To ensure full employment, increase productivity, and reduce costs of welfare and crime Part-time work for elders, elimination of early retirement, and protection of the trust funds of social security Sustaining People during Transition We will need: A universal public baseline health care system Expensive medicines may continue to be available through private insurance Sustaining People during Transition A tradition of free consumption hurts the economy by wasting emergy Sustaining People during Transition Our collective love of the automobile limits other things – jobs, health, education and environment quality We can sustain for some time what is most important in mature nations Descent Descent As we move into ‘descent’, what should we expect, and how do we react? Starting Down Reorganizing Cities Restoring Waters Refreshing the Landscape Transmitting Knowledge Starting Down Chapter 13 Starting Down – Beginning Descent There should be task forces throughout society working on descent Within one generation we could see a reversal of attitude so that descent is good and 20th Century growth is bad (very likely, already happening) Starting Down – Beginning Descent We should change attitudes now to avoid the inefficiency of trial and error The education system should teach the changes necessary for a prosperous way down Starting Down – Beginning Descent To maintain the standard of living, the population has to decrease at the same or greater rate as the empower With less wealth (emergy) to process, the money supply needs to be decreased to avoid inflation Starting Down – Beginning Descent Policies should stop commodity exports except those necessary to generate the dollars for imported fuels and information Starting Down – Beginning Descent During descent banks may acquire new roles such as financing contraction Especially in a time of descent the real wealth system can hold its monetary value better than bank savings Starting Down – Beginning Descent A mechanism is needed to program a gradual, noncatastrophic deflation of the excess money held in stocks and bonds Starting Down – Beginning Descent Perhaps the most important descent policy is cutting salaries uniformly They propose an international minimum living wage, agreed to by treaty Starting Down – Beginning Descent Information centers may be expected to develop more around mountains where hydro power is more abundant If descent is to be prosperous, priority has to go to sustain global information systems Starting Down – Beginning Descent To be prosperous, descent requires a reduced population, less money, and smaller salaries Starting Down – Beginning Descent Governments and banks will need to help finance initiatives for downsize and redevelopment The economy will issue fewer stocks and bonds, borrow less, and develop lower interest rates Starting Down – Beginning Descent International treaties can control global capitalism with an international minimum wage With less energy and a shortened energy hierarchy, some achievements of the climax civilization must become dormant Ancient library of Alexandria Starting Down – Beginning Descent Landscapes can be expected to organize with fewer cars Information and medicine can be given priority by allocation of electric power Starting Down – Beginning Descent A deliberate plan for change to avoid apocalypse needs global attention People will need to understand the changes and share a vision of a lessintensive but better world Maya Starting Down – Beginning Descent Guidelines for Orderly Descent Make beneficial descent the collective purpose for this century Dedicate TV drama, literature, and art to adventures about descent Accept small annual declines in empower use Teach descent Starting Down – Beginning Descent Guidelines for Orderly Descent Maintain a stable emergy use per person by reducing populations in a humanitarian way Remove all incentives, dogma, and approval for excess reproduction Reduce salaries and wages as necessary to maintain full employment Reduce population, maintain full employment Starting Down – Beginning Descent Guidelines for Orderly Descent Keep the emergymoney ratio stable by adjusting the money in circulation Borrow less and reduce expectations of profit from stock markets Emergy/Money Ratio Starting Down – Beginning Descent Guidelines for Orderly Descent Develop economic incentives for reducing consumption Develop public opinion, laws, and taxes to discourage unproductive resource use Starting Down – Beginning Descent Guidelines for Orderly Descent Sustain the production of the environment Consolidate knowledge for longterm preservation Starting Down – Beginning Descent Guidelines for Orderly Descent Prioritize the communication of concepts of international respect and cooperation for global sharing Reorganizing Cities Chapter 14 Reorganizing Cities during Descent Reintegrating cities with their region of support and influence may help solve severe urban problems while preparing those cities for the decentralization expected in descent While some cities are still growing, the reorganization to use less fuels is underway in many developed cities Reorganizing Cities during Descent Decentralization is aided if reduced urban populations can cluster around smaller more dispersed centers Towns are already developing at the beltway-trunk line junctions, starting with the shopping centers there Reorganizing Cities during Descent In descent people should move closer to their jobs, use bikes more, reduce car use, parking space, and fuel use Bike Commuter Reorganizing Cities during Descent A public works program can help make changes in city structure while keeping the poor and unemployed in the economy Reorganizing Cities during Descent We can expect decentralized cities to have: Less-intense fuel consumption Less transportation Less strip advertising A smaller percent of regional population Better cycles of materials between cities and environment Longer rotation of building and renewal More efficient spatial patterns Reorganizing Cities during Descent Greens including wetlands, ponds, parks, retention basins, and play fields, can be added to depopulated areas City wetlands Reorganizing Cities during Descent The inner city is likely to retain its roles as a center of information, serving the region through communication technology Reorganizing Cities during Descent City and Regional Reorganization Adapt plans, zoning, and incentives to develop surrounding towns (secondary centers) Provide frequent public transport connecting central cities with the towns Develop surrounding towns Reorganizing Cities during Descent City and Regional Reorganization Include the central city and its suburban towns within the same regional government and taxing authority Taxes from both the city and region are combined used to support both Reorganizing Cities during Descent City and Regional Reorganization Plan now for times when fuel costs eliminate most private cars Limit strip development and unnecessary advertising Reorganizing Cities during Descent Central City Keep the centers of information in the central city (libraries, schools, finance, universities, government offices, and computer centers) Use communications to connect the centers to the people of the region (television, the Internet, phone networks) Keep information centers in central city Reorganizing Cities during Descent Central City Remodel and use the buildings that become vacant with decentralization Restrict cars from centers of information Walking city centers Reorganizing Cities during Descent Surrounding Towns Restructure the spatial distribution of housing, businesses, and transportation so that housing and environmental amenities can be near the jobs Reorganizing Cities during Descent Surrounding Towns Encourage diversity of business in smaller centers to help the one-stop shopping that uses less transportation Transfer unemployed and homeless people to public works jobs in redeveloping smaller towns Diverse small town shopping Reorganizing Cities during Descent Environment Encourage people to reuse products, to recycle materials from consumers to industry, and to disperse only the dilute, lowtransformity wastes to the environment Reorganizing Cities during Descent Environment Use rural wetlands for recycling city storm waters and wastewaters back to nature Rural Wetlands Reorganizing Cities during Descent Environment Perforate sidewalks and parking lots to increase percolation of rain so that trees can grow larger The area of roots receiving water and nutrients needs to be the same as the crown of the mature trees Brick sidewalks let trees grow larger Reorganizing Cities during Descent Emergy Evaluations Use emergy evaluation to select land uses with maximum public benefit (different from maximum monetary profit to individuals) Use empower density and transformity to locate activities Restoring Waters Chapter 15 Restoring Waters during Descent Hydrological cycle For prosperous descent, the economy as it selfdesigns can achieve more by fitting into the global hydrologic cycle Restoring Waters during Descent More empower is generated by adapting society to the multiple values of rivers, estuaries, and beaches Restoring Waters during Descent Human settlements and the ecosystems around the rivers can reorganize so that the economy better fits the water system Highly urbanized river and coastal ecosystems Restoring Waters during Descent Nature’s treatments, properly used, work for the economy so that tax-driven technologies don’t have to fill the same functions: Use floodplains to maintain water quality Restore estuarine circulation Remove jetties Stop pumping coastal groundwaters Operate lower-intensity aquaculture ponds Restore reefs Set levees back from the shore Restoring Waters during Descent Coastal fisheries can recover when fishing pressure decreases and some of the nutritive discharges are restored Restoring Waters during Descent The energies of mountain waters will still be needed to produce hydroelectric power for society’s information systems Hualien Hydroelectric Power Refreshing the Landscape Chapter 16 Refreshing the Landscape during Descent During descent, assuming population decrease, society can reorganize rural landscapes symbiotically with decentralized cities Natural capital can be restored Symbiotic reorganization of cities with rural landscapes Refreshing the Landscape during Descent Environmental contributions based on renewable resources can be increased by rotating lands, reclaiming and reforesting bare lands, and sustaining complex forests and biodiversity Complex forest Rotating and fallowing fields Refreshing the Landscape during Descent Less-intensive agriculture and forestry will require more lands and more labor Recycling can replace most mining Labor-intensive rural farming Transmitting Knowledge Chapter 17 Transmitting Knowledge through Descent Part of global information is in the intellectual knowledge of society, and part is biotic information in the genes of humans and the Earth’s life-support biodiversity Transmitting Knowledge through Descent Sustaining the biotic information depends on maintaining large areas of diverse ecosystems through critical times of transition when human populations exceed resources Maintain vast areas of forest Transmitting Knowledge through Descent There are resource limits to the amount of genetic and knowledge information that can be sustained This is because of the great wealth (in emergy) used to develop and maintain information Information is a storage, and (which means that its like other storages requires transformities are high) energy to be maintained Transmitting Knowledge through Descent Only part of our information will be used by our civilization in descent For adaptability and long range progress, we also need to preserve unused knowledge Ancient library of Alexandria in Egypt preserved much unused knowledge from antiquity Transmitting Knowledge through Descent To maintain knowledge, the institutions for education, communication, and technology will require large amounts of electrical power Hydropower for electricity Transmitting Knowledge through Descent Information processing by television helps develop a globally shared culture and peace ethic But to be efficient, society has to set television priorities among serious purpose, advertisement, and entertainment Set TV Priorities 1. 2. 3. 4. 5. 6. 7. 8. 9. Serious purpose .. .. .. .. .. .. Entertainment Advertisement Transmitting Knowledge through Descent Suggestions for Educational Efficiency Reorganize jurisdictions, laws, taxes, and budgets to give a stateapproved standard education to all children (Taiwan has this) Require this standard for private schools also Transmitting Knowledge through Descent Suggestions for Educational Efficiency Provide daycare for small children, extending through normal working hours as an automatic part of all schools Provide preschool orientation and help in school to those of different languages with the goal that they can be taught in the nations’ primary language without handicap School extending through working hours of parents Transmitting Knowledge through Descent Suggestions for Educational Efficiency Provide after-school activities for all ages Replace high-energy interschool sports teams – oriented toward championships and a few stars – with intraschool sports that include all students Applies to US, not Taiwan Transmitting Knowledge through Descent Suggestions for Educational Efficiency Provide a unified ‘systems’ course in energy, economics, and environment taught by teachers trained to relate these fields to global change A ‘systems’ textbook Transmitting Knowledge through Descent Suggestions for Educational Efficiency Let about half of what is taught be according to standards of federal, state, and local authorities, with the goal of sharing common knowledge and achieving basic skills Let the other half be left for teachers to generate innovations, creativity, and progress Creative learning activities Transmitting Knowledge through Descent Suggestions for Educational Efficiency Encourage the use of new technology like computers and the Internet, experimenting with various new ways of using these in teaching Transmitting Knowledge through Descent Suggestions for Educational Efficiency Organize school schedules to occupy students in learning through the whole day and year-round Learning can include after-class projects, internships, and vocational experiences making use of community help Transmitting Knowledge through Descent Suggestions for Educational Efficiency Let schools supplement medical care, nutrition, and job placement for students who do not get this at home Use parent-teacher activities to get more community support for all the children Transmitting Knowledge through Descent Suggestions for Educational Efficiency Organize districtwide programs for racial and ethnic variety in schools Transmitting Knowledge through Descent Education is the transmitter of knowledge With the right kind of downsizing, nonacademic waste can be eliminated and the university’s intellectual functions emphasized The great university, although smaller, may be the best hope for leading descent and preserving knowledge from the Era of Growth The ‘great university’ is small in size, but focused solely on academic functions Restoration Stewardship for the Period of Restoration If the Earth is to maximize its performance through the full cycle of growth, transition, descent, and restoration, a human culture will be needed that assists environmental restoration Stewardship for the Period of Restoration We may expect ethics to develop in which people collectively aid net production processes that restore the resource reserves, the soils, the forests, the peat deposits, and the mineral deposits moving slowly up from the ground in the Earth cycles Stewardship for the Period of Restoration As sometimes attributed to past cultures, people may find glory in being an agent of the Earth Stewardship for the Period of Restoration It remains to be seen whether the social mechanisms will be conscious, logical, emotional, ritualistic, regimented, or by some means that we can’t imagine Stewardship for the Period of Restoration All members of society must preserve knowledge, sustain progress, and serve the Earth in ways appropriate to the stage of its cycle
