Quality over Quantity – Growing Nutrient Dense Food in Urban Gardens

By Kat Gawlik, forgreenies.com If we are to grow and produce enough food to meet our families’ nutritional needs in an urban situation, we need to go beyond organic, to remineralise the soil where there are deficiencies, cultivate soils rich with microbes and to grow food that is nutrient dense.

How to build a Geo-Solar Greenhouse

Imagine if you could trap the energy of the sun and store it, in a bank, for future use when you needed it in the winter? That’s the principle of Annualized Geo-Solar. A fancy name, but a clever way of storing the heat in the ground and using it to warm your greenhouse when its needed in the cold winter months. In the video Geoff Lawton visits a massive community […]

Hey! It’s High Cold Dry and Windy and Doing just Great!

Every now and then you come across climate that is not so user-friendly. It’s in the High, Dry and Cold and Windy desert environment of Nevada’s high country near Reno. A place with many challenges. Sagebrush and horse trails dot the landscape. It is cowboy country. So what on earth is a Permaculture teacher doing in such a windswept environment? Neil Bertrando lives here and in three years has used […]

SMART Permaculture in South Ethiopia (Part 2)

This will all make a lot more sense if you’ve read part 1 of this article. But anyway, to cut a long story short, it is about designing a PC demo site and training centre in a little market town called Bonosha, in the south Ethiopian ethnic zone of Hadiya. This is to be the nerve centre of a network of solar-powered community-serving water, WASH and Permaculture projects spanning the […]

Finding Water in the Desert

We were recently filming in Nevada, USA, visiting interesting high dry and cold climate systems. We went out in search of a salt pan to film as a specific landscape feature. Whilst on our journey we came across a large sand dune. It was a mighty Erg, an Erg is a wind blown mountain of sand that resembles a sand dune and they have a classic ability to hold moisture […]

A Canadian Rocket Stove Powered Greenhouse

How does Permaculture function in cold climate latitudes? Recently Geoff Lawton and his crew visited engineers Rob and Michelle Avis at their home in Calgary, Canada. Rob and Michelle have transformed their urban garden into an outstanding example of good design. They run Verge Permaculture and actually encourage the neighbouring children to pick and sample the berries and vegetables that are grown in their front yard.

China’s Solar Panel Production to Double by 2017

by J. Matthew Roney, Earth Policy Institute China installed a world record amount of solar photovoltaics (PV) capacity in 2013. While this was the first time the country was the number one installer, China has led all countries in making PV for the better part of a decade. China now accounts for 64 percent of global solar panel production — churning out 25,600 megawatts of the nearly 40,000 megawatts of […]

Earthworker – Australia’s First Worker-Owned Green Manufacturing Cooperative

The Earthworker Cooperative is a community-led initiative addressing two significant problems; the stark reality of climate change, and a lack of secure, dignified work in sustainable industries. Earthworker is responding to these issues by setting up an Australia-wide network of community-owned cooperatives in sustainable industries. This is beginning with Eureka’s Future – a worker-owned factory manufacturing high-quality solar hot water systems in Morwell, Victoria, in the heart of Australia’s coal-dominated […]

Wave Carpet – Harnessing Wave Energy

https://www.youtube.com/watch?v=EWnY-XFihVQ Professor Reza Alam and his PhD students in Mechanical Engineering Department, University of California, Berkeley, are testing out a prototype of a device which can produce electricity and provide clean drinking water for coastal communities throughout the world. Called a ‘wave carpet’, it harnesses the predictable wave power to obtain usable energy. As the waves roll through, the carpets motion produces hydraulic pressure energy. This energy can to used […]
