Urban Ecological Amplification Concept



Life is intelligence and virtually the same.  Nature provides everything. 


Just as cities serve as centers of intelligence amplification they can serve as centers of ecological amplification as engines of ecological repair.  Rather than net drains on the environment cities can be reinvented to have minimal environmental footprints and ultimately provide net-positive ecological amplification and dense ecosystems to restore the environment along with the requisite reinvention of the very nature of civilization itself.  In the process of solving the extremely critical and difficult problem of accelerating ecological devastation the solution sets should be quite beautiful, elegant, and far-reaching.

So far, nothing proposed or otherwise seems to come close to doing this.

Human mobility may be considered the first solution set within this framework where global transportation can be rapidly reinvented to incur less than one percent of its current environmental drain with the viral implementation of net-zero mobility and transit.

Friday Fabulous Flower – At the Stage of Seed Dispersal

http://phytophactor.fieldofscience.com/2011/01/friday-fabulous-flower-at-stage-of-seed.html

This isn’t precisely a flower, but then again it is a flower at the stage of seed dispersal, but a very pretty and unusual image the result of having gelatinous seed coats. This also isn’t exactly a common plant especially when viewed this way. So who recognizes this very nifty image?



Closing the seed dispersal loop_Benjamin C.Wang and Thomas B. Smith


Box 1. The seed dispersal cycle

It is important to distinguish between the process of seed dispersal, whereby seeds are moved from parent plants, and the seed dispersal cycle, which is a succession of processes (including the process of seed dispersal) whereby seeds produced by an adult plant are moved from the parent plant, germinate to seedlings, and recruit to adult plants,
influencing the fruit and seed availability of the next generation (Fig. I). Although seed dispersal is only one of the many processes in this cycle, we have chosen to call it the seed dispersal cycle to emphasize its role as a ‘demographic bridge’ linking the end of the reproductive cycle of adult plants with the establishment of their offspring [a]. Not all seeds are dispersed, and most dispersed seeds do not complete the seed dispersal cycle. However, the parents that produce seeds that successfully complete the cycle pass a disproportionate amount of their genes to the next generation and thus have a disproportionate influence on the vegetation composition of the succeeding generations.

and its consequences: (1) Working forwards entails trying to follow the seed dispersal
process in the direction that it happens in nature (in the direction of the arrows). These
studies tend to focus on patterns and processes on the right side of Fig. I (given in red),
and many of them are classified as ‘seed dispersal studies’. A major hurdle has been
the difficulty of following the dispersers from parent plants to where they deposit
seeds to track the fates of those seeds. (2)Working backwards examines the
consequences of the seed dispersal process – seed, seedling, sapling, and adult plant
distribution – and tries to deduce the influence of seed dispersal in determining those
patterns. These studies focus on patterns and processes on the left side of Fig. I (given
in green), and many of them are studies of plant demography. Processes (given in
bold) generate the patterns (given in boxes) that can be measured.

[Headline Topic]
In the 20th century we were a people of pure production.
Now we see a direct linear rela­tionship between our consumption needs and grow effects production.

“Era of Mass production à Era of Mass Consumption”



[Consequent problem 1] _ Human resource

Our life is tightly chained to nearby workplace. Except for the case of business trips or vacation tours, it is impossible to imagine a free move from local map. A daily delight has fallen into a trifle value to be able to exchange for special events at a special day. Such situations could entice us into being immersed in ‘consolatory’ fantasy. Market-driven capitals, mega-corporations and mass media, continually providing illusions, are willing to shape our life and even our way of thinking.
We should remember the fact that human resources’ worth is came out from diversity and creativity.

“Manufactured Lifestyle à Passive Thinking”


[Consequent problem 2] _ Natural resource
It is obvious that a majority of raw materials is abandoned for extracting a small amount of main substances. In addition, massive consumption has turned out a vest number of wastes. Such disposable wastes are threatening our cities as well as nature.

“Raw Materialà Disposable Waste”


[Consequent problem 3] _ Spatial resource
The city has been slowly eroding by two different development systems.
Those at the very top have been infatuated with the construction of productive infrastructures while citizens have swiftly occupied lands left for settlement. Each of urban actors had clung to its own old principles with no feedback.
Now there is not enough space in our cities to avoid a collision. Shabby factories, power plants and elevated roads are brazenly in the center of residence area. Top-down and Bottom-up are not incompatible strategies any more.

“Top-down à Bottom-up”


Ironically, the efficiency of producing goods at which we aim has been involving the inefficiency of consuming resources.
“Whenever we ask wrong questions, you will get wrong answers.”
 Now, it is a time to shift the focus of our questions from the efficiency to the sustainability.

Economic History of Hong Kong

http://eh.net/ENCYCLOPEDIA/ARTICLE/SCHENK.HONGKONG


Catherine R. Schenk, University of Glasgow

Hong Kong’s economic and political history has been primarily determined by its geographical location.  The territory of Hong Kong is comprised of two main islands (Hong Kong Island and Lantau Island) and a mainland hinterland. It thus forms a natural geographic port for Guangdong province in Southeast China. In a sense, there is considerable continuity in Hong Kong’s position in the international economy since its origins were as a commercial entrepot for China’s regional and global trade, and this is still a role it plays today.  From a relatively unpopulated territory at the beginning of the nineteenth century, Hong Kong grew to become one of the most important international financial centers in the world.  Hong Kong also underwent a rapid and successful process of industrialization from the 1950s that captured the imagination of economists and historians in the 1980s and 1990s. 

Hong Kong from 1842 to 1949

After being ceded by China to the British under the Treaty of Nanking in 1842, the colony of Hong Kong quickly became a regional center for financial and commercial services based particularly around the Hongkong and Shanghai Bank and merchant companies such as Jardine Matheson.  In 1841 there were only 7500 Chinese inhabitants of Hong Kong and a handful of foreigners, but by 1859 the Chinese community was over 85,000 supplemented by about 1600 foreigners. The economy was closely linked to commercial activity, dominated by shipping, banking and merchant companies. Gradually there was increasing diversification to services and retail outlets to meet the needs of the local population, and also shipbuilding and maintenance linked to the presence of the British naval and merchant shipping.  There was some industrial expansion in the nineteenth century; notably sugar refining, cement and ice factories among the foreign sector, alongside smaller-scale local workshop manufactures. The mainland territory of Hong Kong was ceded to British rule by two further treaties in this period; Kowloon in 1860 and the New Territories in 1898.
Hong Kong was profoundly affected by the disastrous events in Mainland China in the inter-war period. After overthrow of the dynastic system in 1911, the Kuomintang (KMT) took a decade to pull together a republican nation-state.  The Great Depression and fluctuations in the international price of silver then disrupted China’s economic relations with the rest of the world in the 1930s. From 1937, China descended into the Sino-Japanese War.  Two years after the end of World War II, the civil war between the KMT and Chinese Communist Party pushed China into a downward economic spiral.  During this period, Hong Kong suffered from the slowdown in world trade and in China’s trade in particular.  However, problems on the mainland also diverted business and entrepreneurs from Shanghai and other cities to the relative safety and stability of the British colonial port of Hong Kong. 

Post-War Industrialization

After the establishment of the People’s Republic of China (PRC) in 1949, the mainland began a process of isolation from the international economy, partly for ideological reasons and partly because of Cold War embargos on trade imposed first by the United States in 1949 and then by the United Nations in 1951.  Nevertheless, Hong Kong was vital to the international economic links that the PRC continued in order to pursue industrialization and support grain imports. Even during the period of self-sufficiency in the 1960s, Hong Kong’s imports of food and water from the PRC were a vital source of foreign exchange revenue that ensured Hong Kong’s usefulness to the mainland. In turn, cheap food helped to restrain rises in the cost of living in Hong Kong thus helping to keep wages low during the period of labor-intensive industrialization.
The industrialization of Hong Kong is usually dated from the embargoes of the 1950s.  Certainly, Hong Kong’s prosperity could no longer depend on the China trade in this decade.  However, as seen above, industry emerged in the nineteenth century and it began to expand in the interwar period. Nevertheless, industrialization accelerated after 1945 with the inflow of refugees, entrepreneurs and capital fleeing the civil war on the mainland. The most prominent example is immigrants from Shanghai who created the cotton spinning industry in the colony.  Hong Kong’s industry was founded in the textile sector in the 1950s before gradually diversifying in the 1960s to clothing, electronics, plastics and other labor-intensive production mainly for export.
The economic development of Hong Kong is unusual in a variety of respects.  First, industrialization was accompanied by increasing numbers of small and medium-sized enterprises (SME) rather than consolidation.  In 1955, 91 percent of manufacturing establishments employed fewer than one hundred workers, a proportion that increased to 96.5 percent by 1975. Factories employing fewer than one hundred workers accounted for 42 percent of Hong Kong’s domestic exports to the U.K. in 1968, amounting to HK$1.2 billion.  At the end of 2002, SMEs still amounted to 98 percent of enterprises, providing 60 percent of total private employment. 
Second, until the late 1960s, the government did not engage in active industrial planning. This was partly because the government was preoccupied with social spending on housing large flows of immigrants, and partly because of an ideological sympathy for free market forces.  This means that Hong Kong fits outside the usual models of Asian economic development based on state-led industrialization (Japan, South Korea, Singapore, Taiwan) or domination of foreign firms (Singapore) or large firms with close relations to the state (Japan, South Korea). Low taxes, lax employment laws, absence of government debt, and free trade are all pillars of the Hong Kong experience of economic development.
In fact, of course, the reality was very different from the myth of complete laissez-faire. The government’s programs of public housing, land reclamation, and infrastructure investment were ambitious. New industrial towns were built to house immigrants, provide employment and aid industry.  The government subsidized industry indirectly through this public housing, which restrained rises in the cost of living that would have threatened Hong Kong’s labor-cost advantage in manufacturing. The government also pursued an ambitious public education program, creating over 300,000 new primary school places between 1954 and 1961.  By 1966, 99.8% of school-age children were attending primary school, although free universal primary school was not provided until 1971. Secondary school provision was expanded in the 1970s, and from 1978 the government offered compulsory free education for all children up to the age of 15.  The hand of government was much lighter on international trade and finance. Exchange controls were limited to a few imposed by the U.K., and there were no controls on international flows of capital.  Government expenditure even fell from 7.5% of GDP in the 1960s to 6.5% in the 1970s.  In the same decades, British government spending as a percent of GDP rose from 17% to 20%.
From the mid-1950s Hong Kong’s rapid success as a textile and garment exporter generated trade friction that resulted in voluntary export restraints in a series of treaties with the U.K. beginning in 1959.  Despite these agreements, Hong Kong’s exporters continued to exploit their flexibility and adaptability to increase production and find new markets.  Indeed, exports increased from 54% of GDP in the 1960s to 64% in the 1970s.  Figure 1 shows the annual changes in the growth of real GDP per capita.  In the period from 1962 until the onset of the oil crisis in 1973, the average growth rate was 6.5% per year.  From 1976 to 1996 GDP grew at an average of 5.6% per year. There were negative shocks in 1967-68 as a result of local disturbances from the onset of the Cultural Revolution in the PRC, and again in 1973 to 1975 from the global oil crisis.  In the early 1980s there was another negative shock related to politics, as the terms of Hong Kong’s return to PRC control in 1997 were formalized.

Reintegration with China, 1978-1997

The Open Door Policy of the PRC announced by Deng Xiao-ping at the end of 1978 marked a new era for Hong Kong’s economy.  With the newly vigorous engagement of China in international trade and investment, Hong Kong’s integration with the mainland accelerated as it regained its traditional role as that country’s main provider of commercial and financial services. From 1978 to 1997, visible trade between Hong Kong and the PRC grew at an average rate of 28% per annum. At the same time, Hong Kong firms began to move their labor-intensive activities to the mainland to take advantage of cheaper labor.  The integration of Hong Kong with the Pearl River delta in Guangdong is the most striking aspect of these trade and investment links.  At the end of 1997, the cumulative value of Hong Kong's direct investment in Guangdong was estimated at US$48 billion, accounting for almost 80% of the total foreign direct investment there. Hong Kong companies and joint ventures in Guangdong province employed about five million people.  Most of these businesses were labor-intensive assembly for export, but from 1997 onward there has been increased investment in financial services, tourism and retail trade.
While manufacturing was moved out of the colony during the 1980s and 1990s, there was a surge in the service sector.  This transformation of the structure of Hong Kong’s economy from manufacturing to services was dramatic.  Most remarkably it was accomplished without faltering growth rates overall, and with an average unemployment rate of only 2.5% from 1982 to 1997.  Figure 2 shows that the value of manufacturing peaked in 1992 before beginning an absolute decline. In contrast, the value of commercial and financial services soared.  This is reflected in the contribution of services and manufacturing to GDP shown in Figure 3. Employment in the service sector rose from 52% to 80% of the labor force from 1981 to 2000 while manufacturing employment fell from 39% to 10% in the same period.

Asian Financial Crisis, 1997-2002

The terms for the return of Hong Kong to Chinese rule in July 1997 carefully protected the territory’s separate economic characteristics, which have been so beneficial to the Chinese economy.  Under the Basic Law, a "one country-two systems" policy was formulated which left Hong Kong monetarily and economically separate from the mainland with exchange and trade controls remaining in place as well as restrictions on the movement of people.  Hong Kong was hit hard by the Asian Financial Crisis that struck the region in mid-1997, just at the time of the handover of the colony back to Chinese administrative control. The crisis prompted a collapse in share prices and the property market that affected the ability of many borrowers to repay bank loans.  Unlike most Asian countries, Hong Kong Special Administrative Region and mainland China maintained their currencies’ exchange rates with the U.S. dollar rather than devaluing.  Along with the Sudden Acute Respiratory Syndrome (SARS) threat in 2002, the Asian Financial Crisis pushed Hong Kong into a new era of recession with a rise in unemployment (6% on average from 1998-2003) and absolute declines in output and prices.  The longer-term impact of the crisis has been to increase the intensity and importance of Hong Kong’s trade and investment links with the PRC. Since the PRC did not fare as badly from the regional crisis, the economic prospects for Hong Kong have been tied more closely to the increasingly prosperous mainland.

Forward flight of swallowtail butterfly with simple flapping motion


Among the various types of flying insects, swallowtail butterflies have unique morphological features. Their wing area is very large relative to their body mass, and their flapping frequency is low. ...... Another feature of swallowtail butterflies is the small degree of freedom of the wing motionThe fore wing partly overlaps the hind wing and they flap as one large wing with little feathering. The feathering is structurally restricted by the wing connectionThis means that the ability of butterflies to actively control the aerodynamic force of their wings is limited and the undulating body motion is produced passively by simple flapping.
........
To clarify the passive body motion in butterfly-type flapping flight, we fabricated a tailless ornithopter having the same mass and wing shape as an actual swallowtail butterfly. This ornithopter enabled us to observe the passive body motion caused by simple mechanical flapping in free flight. We also clarified the effect of the wing stiffness on the passive body motion by changing the wing venation of the ornithopter. Our experiments demonstrated that the forward flight of a swallowtail butterfly is realized by simple flapping without feedback control of the wing motion and that passive deformation of the wing significantly affects the passive body motion and resultant aerodynamic coefficients.


Simple flapping motion was achieved by means of a rubber-band-driven crank mechanism that made the wings flap vertically relative to the body at 10 Hz. 

A butterfly wing consists of thin membranes supported by wing veins extending from the wing base to the outer edge. The wing stiffness depends on the vein pattern(Wootton 1993).


To emulate the stiffness distribution of an actual wing, we fabricated the artificial wings with plastic veins mimicking those of an actual swallowtail butterfly (figure 2(a)). A mold for the veins was fabricated by plasma dry etchingand the veins were molded on a thin polymer film.
.........
The longitudinal position of the center of gravity was adjusted by changing the longitudinal position of a 0.04 g balance weight attached to the body of the ornithopter.....




The passive flight motion must depend on the design of the wings. In particular, the wing deformation determined by the wing stiffness presumably affects flight performance (Wootton
1993). A butterfly wing consists of thin membranes supported by wing veins extending from the wing base to the outer edge, and the wing stiffness depends on the vein pattern

4. Conclusion
Using the butterfly-type ornithopter, we demonstrated that the undulating body motion caused by simple flapping of swallowtail butterflies in forward flight has the effect of enhancing the lift coefficient during downstroke. The enhanced lift coefficient at the beginning of downstroke in
free flight exceeded 3.0, which is more than four times that in a steady flow. Though the drag coefficient also increased, the lift coefficient was large enough to keep the thrust coefficient
positive. This lift and drag enhancement was attributed to large angle of attack caused by the passive up-down body motion. The body motion was greatly affected by the wing deformation
depending on the wing stiffness and resultant aerodynamic coefficients in free flight. Wing veins are needed to prevent feathering deformation and produce a large up–down body motion.
Since butterfly-type flapping flight can be realized with simple flapping motion without feedback control, butterfly aerodynamics can be applied to future aerodynamic systems

Interview: Michael Pawlyn on Biomimicry



Why were you drawn to biomimicry?
As a teenager I was torn between studying architecture and biology and eventually chose the former. I was also quite politicized about environmental issues in my early teens after a relative gave me a copy of the Club of Rome’s “Blueprint for Survival”. When I joined Grimshaw to work on the Eden Project, I realized that there was a way to bring these strands together in pursuit of sustainable architecture inspired by nature.
You say we are entering the ecological age. What does that mean exactly?
As I see it, this is the age in which we have the knowledge, technology and imperative to formulate a truly sustainable way of living rather than pursuing approaches that simply mitigate negative impacts.
What are some of the most interesting examples, apart from the Eden Project, of existing architecture that uses biomimicry as its guiding principle?
Pier Luigi Nervi’s Palazzetto dello Sport, an indoor arena in Rome, is a masterpiece of efficiency inspired by giant Amazon water lilies. Many of Nervi’s projects were won in competitions and the secret to his success was his ability to produce the most cost-effective schemes. In a satisfying parallel with the refining process of evolution, the combination of ingenuity and biomimicry led to a remarkable efficiency of resources.
The Eastgate Centre in Harare, Zimbabwe by Mick Pearce, is based on termite mounds. It manages to create comfortable conditions for the people inside without air-conditioning in a tropical environment.
What species in nature are you most in awe of and why?
Camel’s nostrils are miracles of heat exchange and water recovery engineering. We are currently looking at cuttlebone(
오징어 ) and bird skulls(두개골) to help design more efficient concrete structures for office buildings. The combustion(연소) chamber in the abdomen(하복부) of a bombardier beetle mixes two high explosives from fuel tanks with valves that open and close 200 times a second—it is being studied in order to develop needle-free medical injections, more efficient fuel injection systems and more effective fire extinguishers.
Not everything in nature is innocuous. Which are the species you would not want to “mimic”?
There are quite a few species that have been studied by defense industries in order to develop sophisticated weapons using parasites, natural toxins, germ warfare and the like. This is why some people make a distinction between “biomimicry” (which is specifically about developing sustainable solutions) and the more general term of “biomimetics”.
You have said that environmentally sustainable architecture tends to focus on mitigation, when it should be regenerative and restorative. How achievable is this?
Humans are accustomed to engineering things to maximize one goal, whereas ecosystems have evolved towards an optimized overall system. We are only slowly embracing the benefits of designing the kind of synergistic systems like the Cardboard to Caviar project (a closed-loop scheme which takes restaurant waste, turns it into horse bedding, feeds it to worms who in turn are fed to fish whose caviar eventually ends up back on the plates of the restaurant) and the Sahara Forest project.
It is also partly down to conventional economics, which externalizes issues such as pollution, liquidation of natural capital and so on. If we were to shift some taxation away from employment and towards the use of resources it would reward resource efficiency.
How would the construction industry have to change?
We need to get better at procuring the built environment in a way that delivers the maximum long-term value for the minimum long-term cost. At the moment, progress is hampered by short-term thinking, conventional economics and collaboration that do not lead to optimized results.
Why is getting something like the Sahara Forest project off the ground so slow? It seems like this is innovation with few downsides.
The powerful vested interests of oil and motor companies—both of which provide extensive funding to political parties—are a major impediment.
Short term ways of thinking also tend to favor solutions that produce quick profits at the expense of long-term loss. I think this occurred in the late ’80s and early ’90s when developers were fairly brazen about saying that they weren’t interested in anything with a payback period. We now need to create investment models that allow people to invest in longer term projects that deliver value far into the future.
What other projects are you working on at the moment?
I’m working on a concept study for a biomimetic office building—essentially using biomimicry to completely rethink the workplace with the aim of producing a scheme that is as far as possible self-heating, self-cooling and self-ventilating, entirely day-lit and a net producer of energy. Plants will also be incorporated to boost human productivity. A radical new approach to designing IT servers that delivers a factor-10 reduction in carbon emissions is possibly on the cards as well.
