Permaculture, The Way of Life Towards Sustainable Living


I guess everyone is familiar with the term sustainable living, and the cost associated with having to adopt the technology part of it. In this article however, another way of life known as Permaculture, a combination of two words – permanent and culture, is another alternative route towards sustainability. It is the science of using natural functions to create an environment that is sustainable in all its functions and in every way. It is the creation of sustainable human habitats by following nature’s patterns. It uses the diversity, stability and resilience of natural ecosystems to provide a framework and guidance for people to develop their own sustainable solutions to the problems facing their world, on a local, national or global scale. It is based on the philosophy of co-operation with nature and caring for the earth and its people.
Permaculture Definition
  • A globally recognized environmental design methodology.
  • A holistic ecological approach to the design and development of human settlements that takes into account food production, structures, technologies, energy, natural resources, landscape, animal systems, plant systems, and social and economic structures.
  • About working with, rather than against nature. It provides the tools to satisfy our needs in a way that sustains the earth, future generations and ourselves.
  • Inspired by traditional wisdom, especially the sustainable farming cultures of Asia, India and Africa and incorporates new appropriate methods and technologies.

Ethics & Principles
Essentially, the 3 pillars of Permaculture consisted of,
Earth Care – is about working with nature, not against it – not using natural resources unnecessarily or at a rate at which they cannot be replaced. It also means using outputs from one system as inputs for another and so minimizing wastage.
People Care – is about looking after ourselves as individual and everyone in a community as people, not just the world we live in. Self-reliance, co-operation and support of each other should be encouraged. People care is also about our legacy to future generations.
Fair Share – is about having to share the earth we live in – with each other, with other living things, and with future generations. Limiting our consumption, especially of natural resources, and working for everyone to have access to the fundamental needs of life – clean water, clean air, food, shelter, meaningful employment, and social contact.

Permaculture and Sustainability
Sustainability is “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (UN Agenda 21). Sustainability of the environment, systems, and the people is a central concept that the Permaculture Design Systems provides solutions for.
Permaculture is a design system for creating sustainable human environments. The ecological and biological processes of the land, plants, animals, nutrient cycles, climatic factors and weather cycles are all examined and incorporated into a productive, functional Permaculture System. Elements in each system are viewed in relation to other elements, and the outputs of one element become the input of another. Inhabitants’ needs are provided for through proven technologies for food, energy, shelter and infrastructure. Within Permaculture Systems, work is minimized, “wastes” becomes resources, productivity and yields increase, and the environment is restored.

Permaculture aims to create stable productive systems that provide for human needs, harmoniously integrating the land with the people not only for today but also the future.

In The Star article dated 24th July, 2010 by Joleen Lunjew, Permaculture is slowly and surely developing in Malaysia.


A Dane, by the name of Shaykh Hassan Henning Pedersen, who lives in Indonesia, is a naturopathic doctor, permaculture designer and master of several martial arts systems with more than 25 years of experience in sustainable living. He has been involved with NGOs and activists since he was a teenager but only got into permaculture a decade ago. Pedersen was in Malaysia organizing workshops and teaches hands-on permaculture.

Among Pedersen’s main efforts in walking the talk is transforming his home in East Java into an eco-friendly showhouse where water catchments are used to collect rainwater, which in turn is used to breed fish and water the plants. He grows plants wherever possible and uses kitchen and fish waste as fertiliser. Pedersen does not own a car and eats 80% of his food raw.
“I have travelled to 26 different countries in 20 years and have never needed a car. It’s too destructive to the environment. I’d rather take public transportation. Regarding food, good enzymes are killed at 40°C, so why consume food that has less nutrients? Apparently, his whole family adopts a similar eating habit, and his eldest son, who is 9½ years old, has never been sick in his life.”

Pedersen’s way of life has inspired many to start practicing sustainable living. Among his students, Atika Irfan, 36, says she hopes to learn how to become more sustainable after completing her workshop.
The Pakistani, who has been living in Malaysia with her Malaysian husband for 14 years, is now thinking about building a rainwater catchment system, rearing her own fish and prawns, and starting her own salad garden. She currently buys only local products from the local markets to minimize consumption of imported food.
“Over the years, she had realized that companies are all about making profit. Our meat is contaminated with hormones, and chemical pesticides have been making us ill. My mum’s medication costs RM500 each month for 30 pills. Health problems run in my family. I can’t afford the cures so I don’t wish to be sick,” says Atika.

Another student, Awaludin Mohal, 68, is moving towards making his 0.8ha land in Janda Baik fully sustainable in preparation for the peak oil phenomenon. Analysts believe that when the oil runs out, the economy will collapse and food will become scarce — Awaludin is giving himself a headstart.
“Food will be a problem when the economy collapses. History shows that people will even kill for food, just like during the 1930s Great Depression. I have to think about my family. It’s better to be prepared than sorry,” he says.
Awaludin grows all sorts of vegetables on his farm and rears his own chickens, geese and fish.
“I’m looking to grow worms and maggots for my chickens. Worms are also good for the soil. I feed my carp banana leaves and my tilapia eats tapioca leaves,” adds Awaludin, who plans to build an eco-friendly house in the near future.

However, permaculture had made it presence in Malaysia sometime ago, in the small town of Batu Arang. A small community of permaculturist have been living and practicing exactly what have been described herewith for quite awhile. The community teaches, does training and host permaculturist from all over the world whom drop-by every now and then. Check out Embun Pagi and you will probably be fascinated by their activities. So, now there is a choice of how we should ride the sustainability wave, the way of Permaculture, where it is inexpensive and ensures our well-being are taken care with rising cost of living.

Hybrid Technology: Key Towards Sustainable Mobility?


Recently, people have been talking a lot about different environmental issues such as the worldwide phenomena of global warming, climate changes, different types of pollutions, flora and fauna conservation, large-scale deforestation activities and sustainable energy. All of these issues, I would personally say that sustainable energy has the largest impact on our daily activities. Since a few years ago, every vehicle owner has been thinking thoroughly about coping with the fuel price hiking in the market. So, I certainly believe that now is the best period for us to look at possible and practical solution. Terms such as hybrid vehicle might pop up in our minds while thinking for the best answer. Oh, even our senior post an article about electric car which is very much related to hybrid technology.



So, what about this hybrid vehicle? Hybrid vehicle refers to vehicle that is powered by more than one power source. Technically, hybrid vehicles can be categorized into two classes; series hybrids and parallel hybrids.



Series hybrids have a gas engine that powers the generator. The generator then charges the batteries and powers the electric motor. The gasoline engine doesn't power the vehicle on its own. The electric motor runs all the time and the gas engine comes on only when needed. This vehicle gets better mileage around town, where the electric motor is doing most of the work.



The parallel kind has a fuel tank for the gas engine and batteries for the electric motor. Both the engine and the electric motor can turn the transmission and power the vehicle. The small gas engine runs the car and the electric motor comes on when needed to boost power. This is typically needed for increasing speed, merging and passing other vehicles.



Lately, various designs of hybrid cars are showing up in the market which indirectly giving a sign of positive commercialization in the future. From small and compact electric cars, evolving to” spacious and sporty sedan car” and then reaching to super sport cars, most of the developed cars are gaining increasing interest from potential buyers worldwide. Furthermore, the main benefits of hybrid vehicles (i.e. able to reduce fuel cost and air pollutant emission) are also strring up the interest.

If you are enthusiastic about cars as well as the future of our environment, or at least you love to look at green engineering, it is worth to look at some of the available design of hybrid concept cars and recently launced hybrid cars in current market.



NISSAN LEAF (NOW ON SALE)






PROTON EMAS CONCEPT CAR ( MALAYSIAN FUTURE CAR =) )






PORSCHE 918 SPYDER HYBRID SUPER CAR (HYBRID SUPER CAR WITH ELECTRIC PLUG-IN)





VOLSWAGEN ELECTRIC MILANO TAXI




TOYOTA 3RD GENERATION OF PRIUS HYBRID





Looking at the pictures above, the hybrid technology is offering promising alternative for building "a car for tomorrow". Car manufacturers are currently applying different technology adaptation on various category of hybrid cars which seems to be very practical. It is indeed a great effort towards greener world as well as sustainable mobility. Even though the technology offered is not yet perfect, I strongly believe that continuous development of advanced hybrid technology would provide impressive efficiency at affordable price, improved equipments and thus able to significantly reduce the dependence on fossil fuel to power our vehicles. Let's hope that the benefits of hybrid vehicles would really outweigh the cost.
