Rammed earth in Botswana

House Freeman is cool in the hot Botswana desert thanks to an evaporative cooling system, which draws air over solar powered sprinklers, a living roof and thick, thermally efficient walls. The shuttering was reused in, for example, the roof, so nothing was wasted.

Of more than twenty different types of earth construction techniques, rammed earth has been lauded for its durability, sophisticated environmental performance and striking earthen beauty.

Rammed earth construction in South Africa has generally been stigmatised as a substandard and primitive building construction method reserved ‘for the poor’. Yet it is now gaining popularity for community social projects, as well as among wealthier clients. Although a building standard is yet to be formalised in South Africa, the rammed earth industry is established in many African countries, Europe, United States and Australia. This means plenty of expertise and established international building standards already exist and this construction method is now far removed from its primitive roots.

Transition Ethics: The Art of Compromise

This post first appeared on Numundo on 16 February 2016. We are re-posting it here with the permission of  Shayna Gladstone and author Scott Gallant.

To introduce the post, we’d like to share with you why we were so excited to read Scott’s post. Written by Scott Gallant from Rancho Mastatal Sustainability Education Center in Costa Rica, the post is based on his experience teaching the three permaculture ethics during the center’s Permaculture Design Courses, and the realization that a fourth ethic is required in order to facilitate a conversation about compromise.  They filled the gap with the Transition Ethic. Scott quotes Jessi Bloom and Dave Boehnlein, authors of Practical Permaculture, who acknowledge that “the transition ethic says that no one is going from zero to sustainable overnight. Making the transition takes time.” He goes on to say that “We have to meet people where they are at.  We must understand their cultural context.” Continue reading

The dynamic qualities of African Vernacular Architecture

In this guest post written by Jon Sojkowski, he chronicles common misperceptions of African vernacular architecture and how it is being abandoned for the status that comes with living in conventional Western style buildings. He asks whether these modern materials are truly better than the vernacular options.

By Jon Sojkowski

African vernacular architecture is a subject that has had very little attention. The lack of documentation and available data on the internet has led to a severe misunderstanding of a type of architecture that a large percentage of the population in Africa living in on a daily basis. The lack of data has led to negative perceptions regarding African vernacular architecture, mainly that it is temporary, primitive or for the poor. Most people, when they think of a mud hut, get an image of a dilapidated mud structure which is quite small and has a thatch roof. Sadly, this perception exists both inside and outside the African continent, but it is simply not the truth. Continue reading
