Ahmed Baba Institute Library

The new Ahmed Baba Institute of Higher Islamic Studies and Research, completed in 2009, introduces state-of-the-art techniques for conserving, exhibiting, and studying these famous Timbuktu manuscripts. dhk Architects of Cape Town designed phase one of the $8.36 million, 50,000-square-foot Institute, creating an archive of 20,000 manuscripts and a public library with reference materials on the culture of the region.

Andre Spies, the project architect for dhk, designed the institute and now heads his own practice in Cape Town called twothink architecture, which completed phase two — fitting out the interiors. To respect the vernacular architecture of the region, Spies chose to build primarily with mud, which requires maintenance after the annual rains. He found a local mason who mixed mud with concrete to make the facade rain-repellent, and he purchased mud bricks from craftsmen on the streets.

The introduction of a new building is challenging in the low-tech, mud-built setting of Timbuktu. Albakaye Ousmane Kounta, the Malian writer, poet, and storyteller, criticizes the building as “too modern.” Whereas fortresslike walls concealed the internal configuration of the former institute, the new one blurs inside and out with outdoor hallways arrayed along a “free plan.” This modern approach is uncommon in West Africa, where public and private spaces are strictly demarcated to keep out sand, roving donkeys, and itinerant people. The new design encourages access and openness, but it has drawbacks as well. In addition, some spaces — such as the auditorium — have rigid functions not easily adapted to other uses.

Hassan Fathy is The Middle East’s Father of Sustainable Architecture

Green Prophet has railed against projects like Dubai Burj Tower. They have pounded our chests at the audacity of Masdar City’s “zero” footprint claim, and have decried the potential consequences of unsustainable approaches to building and planning. “USD22 billion” for a building project and “sustainable” simply don’t belong in the same sentence.

Egyptian architect Hassan Fathy died in 1989 but left behind a legacy of 160 building projects ranging from small projects to large-scale communities complete with mosques and schools. His impact can still be felt from Egypt to Greece and even New Mexico, where in 1981 he designed the Dar Ar-Salam community. Fathy received several awards for his work, including the Aga Khan Award for Architecture in 1980, and founded The International Institute for Appropriate Technology in 1977.

Emerging Ghana

Enviu selected Emerging Ghana by Ana Morgado, João Caeiro, Lara Camilla Pinho, Maria de Paz Sequeira Braga and Maria de Carmo Caldeira, from Portugal, Mexico and Brazil, as the winner of the Open Source-House competition. The materials used are bamboo and dahoma, a local wood, for the modular and lightweight panels. These are held together with strong rammed earth walls. Due to the modular design, inside and outside spaces can be created depending on different needs and environments. Natural ventilation is archived throughout the building, due to the earth walls that keep the spaces cool and shaded areas.

Terres, d’Afrique et d’Ailleurs

The 2nd Pan African Cultural Festival in Algiers, Algeria includes an exhibit and symposium entitled Terres, d’Afrique et d’Ailleurs, sponsored by the Algerian Ministry of culture and curated by architect Yasmine Terkhi, which facilitated the participation of 19 artisans from 5 countries (Burkina Faso, Nigeria, Niger, Ghana, Nigeria, Algeria) who prepared wall panels in earth using indigenous techniques and motifs from the communities they represented. Invited speakers to the symposium include Ronald Rael, Hubert Gillaud, Hugo Houben, Salma Damluji, Marcello Cortes, Laetitia Fontaine and many other internationally renowned experts in the field of earth architecture.

Musgum Architecture

The Musgum, an ethnic group in far north province in Cameroon, create their tall conical dwellings from compressed sun-dried mud. Called Cases Obos, the profile of the structure is that of a catenary arch— the ideal mathematical form to bear a maximum weight ?with minimal material.

The relief pattern on the surface is a built-in scaffolding that can support the body to allow for maintenance of the structure by the re-application of mud to the surface.

Watertower Skyscraper

The conflict over water and land in Sudan has created political unrest for decades. However, in 2007, scientists from Boston University discovered and underground lake in the region of Darfur, Sudan. This lake is tenth biggest lake in the world (31, 000 m2) and would have great potential in resolving the conflict if managed correctly. Addressing this water issue, Polish architect Hugon Kowalski from H3AR Architect and Design recently proposed a building that allows access to underground waters through the application of water pumps. The form of the building was inspired by a water tower and also by the symbol of the African savanna—the baobab. The building houses water pumps, a treatment plant but also a hospital, a school and a food storage center. This building is meant to provoke economical development but also stimulate cultural exchange and the coexistence of the three different religions and languages in Sudan.

The building walls are constructed using compressed dry stacked clay bricks, made on site using a rough mixture of earth, cement and water. The bricks would be baked in the hot sun, thus, requiring no extra energy and limiting the environmental impact of the materials. The choice of using this technology represents the desire to introduce alternative and sustainable technologies within a context that is tied to standardized though not always optimal building practice.

Two water circulation processes would be in place. First set of extracted water is meant to heat or cool the building, and is accessible to the users. Second, set of extracted water is used for the building itself (i.e. kitchen, toilets).

Dune Anti-Desertification Architecture

Dune Anti-Desertification Architecture investigates adaptive (as opposed to mitigatory) strategies leading to the creation of a climate-conscious
architecture that responds to the extreme environments of tomorrow’s globally-warmed world. Highly speculative yet buildable, the scheme aims to find innovative solutions to combat desertification in the Sahel region of Africa, where sand dunes are currently moving southward at a breathtaking
pace of around 600m per year, ruining the land and making it impossible for the inhabitants of this area to make a living or even stay in their homes. The forced migration of desertification refugees is perhaps more threatening in Nigeria than anywhere else. With a population of over 140 million people, Nigeria is the most populous country in Africa, with serious desertification issues throughout its northern states. It was Nigeria’s former president, Olusegun Obasanjo, who initiated the anti-desertification Green Wall Sahara initiative in 2005. This pan-African scheme seeks to plant a shelterbelt across the continent, from Mauritania in the west to Djibouti in the east, in an attempt to stop the dunes from migrating. The trees are being planted right now.

An architectural response to this campaign would be to go beyond the mere planting of a mitigatory shelterbelt. Habitable spaces can be created in close proximity to the trees. By cutting through the sand dunes and digging down to find water and shade, an artificial oasis can be formed underground.

The sand is solidified using bacillus pasteurii, a microorganism with which professor Jason DeJong has turned sand into sandstone in a mere 1,400 minutes. This technology of organically cementing networks of sand dunes into habitable barriers that stop the desert from spreading has never been proposed before, but on hearing about this project, the professor was enthusiastic: “I do think the application you are talking about is possible”. I’m proposing anti-desertifi cation structures made out of the desert itself, sand-stopping devices made of sand: a poetic proposal that simultaneously works in a sustainable way with local materials and assets.

Special emphasis has been put on finding a solution that is high-tech in result but low-tech in application and construction, with the economical scenario being hard to pin down as this method is virgin territory. It is recognized that poor people are highly vulnerable to the effects of weather, as drought can cause famine while good rains can cause drops in crop prices. The architecture presented here could form a stable base from which to fight back against both effects.

MUMEMO

Mumemo is a blog about a training course carried out in Mumemo (Maputo, Mozambique) on earth construction by two Portuguese architects, Miguel Mendes and Teresa Beirao, during May and August 2006. The project was created for the inhabitants of a new village, created as a resettlement for the victims of the massive floods in the year 2000. The course gave students a wide and solid knowledge about earthen construction and three main techniques (rammed earth, adobe, compressed earth blocs) as well as provided them with the ability to direct similar courses in other communities. During the course, a small 50m2 house was built.
