LEARNING FROM NATURE
BIOMIMICRY: INNOVATION INSPIRED BY NATURE
Janine Benyus coined the term “biomimicry” in 1997 when she published her book Biomimcry: Innovation Inspired by Nature. Benyus, an ever-curious biologist and captivating storyteller, describes biomimicry as “the conscience emulation of nature’s genius.” A less eloquent but perhaps more pragmatic definition is that biomimicry is a sustainable design tool based on emulating strategies used by living things to perform functions that we want our technologies to perform –
everything from creating color to generating energy. The goal of biomimicry is to design products and processes, companies and policies — new ways of living — that are well adapted to life on earth over the long haul.
If you haven’t heard the term biomimicry before, you probably have seen biomimicry in action. Velcro, for example, was designed by emulating the strategy used by burrs to cling to animal fur. Corrugation emulates the strategy used by scallops to create strength with less material. Solar panels emulate the strategy used by leaves to convert sunlight into a useable form of energy. Biomimics around the world are learning how to extract nature’s best ideas and turn them into sustainable design solutions. These innovators are learning to adhere like a gecko, cool buildings like a termite, make fiber optics like a sea sponge, repel microbes like kelp, and run a business like a redwood forest. Like them, we can all learn to look to nature as a model for innovative design solutions.
We can also look to nature as a measure of the sustainability of our designs. Biomimicry applies an ecological standard to judge the “rightness” of our innovations. These standards are expressed in what we call “Life’s Principles”. The idea is that after 3.8 million years of evolution, nature has learned what works, what is appropriate, and what lasts here on earth.
The more we can design our technical world to function like the natural world, the more likely we are to endure on this home that is ours, but not ours alone. For many, the true beauty of biomimicry is that it allows us to look beyond the drawing table – sometimes for the first time. “Biomimicry is a new way of viewing and valuing nature,
based not on what we can extract from the natural world, but on what we can learn from it.” (Janine Benyus). This suggests that as designers we can look at nature not as a reservoir of natural resources, there for our exploitation, but rather as a reservoir of knowledge, of information, of inspiration. We can look to nature as a mentor that teaches us how we can fit the natural world.

INTEGRATING THE MARGINALIZED
TOWARDS A CONNECTED CITY
Making liveable cities and addressing demands of sustainability, peak oil and climate change are same concerns. City thinkers need to come up with cogent solutions to resolve these urgent issues. However, it will be to no avail until the city collective is mobilised to make cities liveable – safe, secure, environmentally responsive and beautiful. Emerging disconnections between people and their city environments is becoming apparent in cities dealing with identity-crisis, crisis of consumerism and with social polarization. Currently almost 3 billion people live in cities. Of these, about a third live in slums. According to the UNHabitat report, that number is likely to double to 2 billion in 30 years’ time unless serious action is taken. In Indian mega-cities, nearly 30-60% of city dwellers live in slums. 93% of all employment and 64% of all savings comes from the informal sector of which slums are a huge part (NSSO, 2002). This informal economy re-introduces neighbourhoods and households as spaces for the production of goods and services while strengthening community relations in these districts. Yet, the people who live in slums are completely marginalized by the mainstream of the city. Where do they belong? Since they develop and operate beyond the formal control of the state, they are not legally part of the city, neither do they belong to other organised structures such as villages. They inhabit a liminal zone which can be spatially characterised as between order and chaos, and between permanence and impermanence. The marginalised survive and evolve with a minimum or complete lack of infrastructure (water, electricity, sanitation, education and transport). Attempts to integrate this informal urbanism into the mainstream have included on-site redevelopment which has introduced new spatial morphologies resulting in social disruption.
Another approach has been the complete displacement of these communities to new sites that lie on city peripheries thus shifting the problem elsewhere. In this context, questions remain on whether there are other ways of working within existing spatial morphologies and troubleshooting problems through democratic participation and empowerment.
With fast growth of slums it becomes critical to address and explore these existing and new geographies of the marginalised and the main stream – of urban poor and rich – in our cities. Will the Technology City of Future with increased global migration and global dependence increase polarization? Alternatively is there a way to utilise strengths of the technological ‘hardware’ and human ‘software’ of the marginalised and the mainstream to create a City of, for and by the people that responds to issues of rapid urbanization and migration.

ECO-TECHNOLOGIES IN ARCHITECTURAL DESIGN
IS ECO-LOGICAL DESIGN SOMETHING DIFFERENT?
Vernacular architecture is of great importance for architects in today’s world of globalization, as it is an immense source from which to learn but not to copy. Copying would be meaningless except possibly from a purely aesthetic point of view. It is after the first oil crisis in the mid 70ies that so-called solar architecture came into being with its main emphasis on energy conservation. However, due to its very rudimental design, it did little to influence mainstream architecture. In the 80ies and 90ies we see a broadening of issues with a more holistic design approach.
I have tried through the years to motivate colleagues in the line that “Less is beautiful”, meaning that bioclimatic design is not only a matter of economy and sustainability. I now believe that we have no more time to wait. With the climate change facts that we know so much about, it is also a matter of our obligation to design and think in an eco-logical manner, which after all should not be an architecture of its own. In our present-day world of extreme morphocracy and morphocompetition the element that will be able to bring things together once more could well be an ecological approach to design as a complementary facet of what is from many points of view so positive: globalism.
The presentation will be complemented with examples of work by A. N. Tombazis and Associates.
