Owing to its significant solar and wind potential, the Middle East and North African (MENA) region has the opportunity to lead the decarbonization of the global steel industry.
Emphasized in a recent report by the Institute for Energy Economics and Financial Analysis, the regional steel industry – which currently represents one of the most competitive globally – has already taken significant strides to decarbonize through the application of direct reduced iron-electric arc furnace technology (DRI-EAF).
Now, with new opportunities emerging across the green hydrogen landscape and government objectives to accelerate the transition even further, the MENA region is set to lead the world in the adoption of green hydrogen within the steel industry.
“The MENA region can lead the world if it shifts promptly to renewables and applies green hydrogen in its steel sector. MENA has an established supply of DR-grade iron ore and its iron ore pelletizing plants are among the world’s largest. In 2021, MENA produced just 3% of global crude steel but accounted for nearly 46% of the world’s DRI production,” said Soroush Basirat, author of the Institute for Energy Economies and Financial Analysis report.
With the region offering the highest potential for photovoltaic power globally – with theoretical production estimated at more than 5.8 KWh per m² – converting existing gas-powered generating plants to green hydrogen would create a carbon-free steel industry in the region. Decarbonizing the steel industry aligns with the World Bank’s prediction that by 2050, more than 83GW of wind and 334GW of solar will be added to the regional energy mix, improving the provision of clean energy and making the conversion to green hydrogen-powered steel production that much simpler.
“MENA’s knowledge of this specific steel technology is an invaluable asset. This production knowledge, abetted by further work on iron ore beneficiation, pelletizing and DR plants, is among the most important steel decarbonization pillars, and will greatly assist MENA’s transition. Compared to other regions, MENA’s existing DRI-EAF capacity means that no extra investment is needed for replacing the base technology. All new investment could be focused on expanding production of green hydrogen among other renewables. If it acts fast, MENA has the potential to lead the world in green steel production,” Basirat said.
In most of the MENA and the Gulf region, we reach for the A/C control when entering any living or working space. But as we casually flip a switch, we tend not to consider all those carbon emissions caused by machines.
After years of indulgence and as witnessed by all of the end results, climate change is forcing all to go green by trying to keep buildings cool as it gets hotter. Greening the Global Construction Industry has already engaged in developing new techniques, tools, products and technologies – such as heat pumps, better windows, more vital insulation, energy-efficient appliances, renewable energy and more imaginative design – has enabled emissions to stabilize the past few years.
The Conversation Weekly podcast is now back after a short break. Every Thursday, we explore the fascinating discoveries researchers are using to make sense of the world and the big questions they’re still trying to answer.
In this episode we find out how “modern” styles of architecture using concrete and glass have often usurped local building techniques better suited to parts of the world with hotter climates. Now some architects are resurrecting traditional techniques to help keep buildings cool.
From western Europe to China, North Africa and the US, severe heatwaves brought drought, fire and death to the summer of 2022. The heatwaves also raised serious questions about the ability of existing infrastructure to cope with extreme heat, which is projected to become more common due to climate change.
Yet, for thousands of years, people living in parts of the world used to high temperatures have deployed traditional passive cooling techniques in the way they designed their buildings. In Nigeria, for example, people have long used biomimicry to copy the style of local flora and fauna as they design their homes, according to Anthony Ogbuokiri, a senior lecturer in architectural design at Nottingham Trent University in the UK.
But in the 20th century, cities even in very hot climates began following an international template for building design that meant cities around the world, regardless of where they were, often had similar looking skylines. Ogbuokiri calls this “duplitecture”, and says it “ramped up the cooling load” due to an in-built reliance on air conditioners.
Alongside this, there was a massive boom in the use of concrete, particularly after the second world war when the Soviet Union and the US started gifting their cold war allies concrete technology. “It was a competition both to discover who actually mastered concrete and who was better at gathering the materials, the people and the energy to make concrete,” explains Vyta Pivo, assistant professor of architecture at the University of Michigan in the US. But too much concrete can contribute to the phenomenon of urban heat islands, where heat is concentrated in cities. Concrete is also a considerable contributor to global carbon emissions.
Some architects and researchers are working to rehabilitate and improve traditional passive techniques that help keep buildings cool without using energy. Susan Abed Hassan, a professor of architectural engineering at Al-Nahrain University in Baghdad, Iraq, focuses a lot on windcatchers in her work, a type of chimney which funnels air through houses to keep them cooler in hot climates. She’s now looking at how to combining underground water pipes with windcatchers to enhance their cooling effects.

It’s an essential component of the design process, where spatial ideations are translated into built form – the design of the prototype. Architectural projects, throughout history and in contemporary practice, have been prototyped to carry out both technical and aesthetic tests, where further insight is gained into the integrity of the design. It’s the blurred line between the experimental and the practical.
Antoni Gaudí’s 1:25 and 1:10 scale plaster models of Sagrada Família can be defined as architectural prototypes, and so can the wooden model of Filippo Brunelleschi’s Florence Cathedral dome. But these are investigations conducted on a smaller scale. It can be argued that architectural prototypes are most effective when built out 1:1, from which further architectural interventions based on the prototype have the security of a design attempt that is not a scaled-down version of the finished product.
But the making of these prototypes is a protracted endeavor – necessitating the complex maneuvering of resources, labor, and capital – for a structure that aims to merely lay the foundations for how similar designs should be approached in the future.
When scrutinized from the perspective of the Global South, this dialogue is complicated further – in countries that have been historically over-exploited and are currently under-resourced, are full-scale architectural prototypes wasteful if they don’t immediately function as a working building? Is it right for these prototypes to simply exist as say, explorations of new materials without serving as a structure that will be in constant use from its inception?
In colonial Africa, architectural experimentation was commonplace, from Fry and Drew in West Africa to Guido Ferrazza in Libya. This experimentation included that of French industrial designer and architect Jean Prouvé, who in 1949 developed Maison Tropicales – prefabricated, modular housing prototypes constructed out of aluminum designed to be easily transported, assembled, and disassembled.
The design problem that the Maison Tropicales had to solve was climatic – as France’s African colonies faced a shortage of housing and civic buildings. The prototype was designed for the equatorial climate, including a veranda with an adjustable aluminum sun-screen. Internally, walls were made of a combination of sliding and fixed metal panels – as glass portholes provided protection against UV rays.
But despite this resourceful, ingenious response to the tropical climate, the Maison Tropicale as a prototype failed. It was no less expensive than locally constructed buildings, and the French colonial bureaucrats did not warm to the industrial appearance of the house. The prototype, ultimately, was a colonial project built for French administrators. A prototype built for the colonial class that proved unpopular with them, and that instead of being widely adopted, was resigned to be a traveling object, making frequent appearances in design exhibitions. This prototype of the African Tropics became a design object that to most, was known outside of its intended context.
But contemporary practice in the Global South has offered up more substantial prototypes, where investigations into materials are coupled with substantial usage. Senegalese firm Worofila’s Ecopavillon in Diamniadio, constructed in 2019, is one such example. Commissioned by the Ministry of the Environment of Senegal, it is built with earth and typha – a type of water reed found in the Senegal River. Woven typha panels provide sound insulation, and when mixed with adobe bricks, provide thermal insulation.
As the prototype is part of the Senegalese government’s initiative to build a new city to ease congestion in Dakar, its usage is still in its early stages. The intention, though, is clear. The Ecopavillon will allow the monitoring of how the building’s materials behave, and performance can be assessed. the behavior of materials and to measure the performance of buildings. Furthermore, it can act as a training venue for craftspeople, where local knowledge of energy-efficient materials can be further developed.
The most tangible example of a living prototype in the Global South, however, is arguably found in Bangladesh, in Marina Tabassum Architects’Khudi Bari. It is a modular mobile housing unit, with an area of 128 square feet. Its light footprint and elevated form mimic the architectural vernacular of the Bengal delta, but more pressingly, it responds to climate change.
In an area with high instances of flash flooding, the raised second level acts as shelter for occupants as they await the receding of the water. In the Chars of Bangladesh – low-lying islands naturally formed by silt from rivers – the spaceframe structure is a crucial response, low cost, durable, and easily assembled and disassembled with minimum labor.
The true success of the Khudi Bari project can only be measured by what happens after the housing modules are built. A pilot project initiated by a non-profit organization affiliated with Marina Tabassum Architects in conjunction with private and governmental donors aims to establish at least 80 to 100 “Khudi Bari” modules in the flood-prone communities of Bangladesh by May 2023.
More crucially, March 2021 saw the first three homes built in collaboration with families, with some adapting their modules, with the vision for the future being that people involved in this pilot project will then become part of the training collective as the modules are initiated in other areas.
Perhaps this is how architectural prototypes built in the Global South should function – as bold, inventive assemblages, that are not only for observation and display, but instead examples of architecture that is dynamic, in use, and living.
Oxford archaeologists discover monumental evidence of prehistoric hunting across the Arabian desert.
They have found over 350 Monumental Hunting Structures labelled and since then known as ‘Kites’ In Northern Saudi Arabia And Southern Iraq Using Satellite Imagery.
Evidence of Prehistoric Hunting across Arabian Desert
Distribution of kite structures in the Levant and in northern Arabia. White: previously documented kites. Red: kites recorded by EAMENA.
Archaeologists at the University of Oxford’s School of Archaeology have used satellite imagery to identify and map over 350 monumental hunting structures known as ‘kites’ across northern Saudi Arabia and southern Iraq – most of which had never been previously documented.
Termed kites by early aircraft pilots, these structures consist of low stone walls making up a head enclosure and a number of guiding walls, sometimes kilometres long. They are believed to have been used to guide game such as gazelles into an area where they could be captured or killed. There is evidence that these structures may date back as far as 8,000 BCE in the Neolithic period.
Kites cannot be observed easily from the ground, however the advent of commercial satellite imagery and platforms such as Google Earth have enabled recent discoveries of new distributions. While these structures were already well-known from eastern Jordan and adjoining areas in southern Syria, these latest results take the known distribution over 400km further east across northern Saudi Arabia, with some also identified in southern Iraq for the first time.
Dr Fradley said: ‘The structures we found displayed evidence of complex, careful design. In terms of size, the ‘heads’ of the kites can be over 100 metres wide, but the guiding walls (the ’strings’ of the kite) which we currently think gazelle and other game would follow to the kite heads can be incredibly long. In some of these new examples, the surviving portion of walls run in almost straight lines for over 4 kilometres, often over very varied topography. This shows an incredible level of ability in how these structures were designed and built.’
Evidence suggests considerable resources would have had to be coordinated to build, maintain, and rebuild the kites over generations, combined with hunting and returning butchered remains to settlements or camps for further preservation. The researchers suggest that their exaggerated scale and form may be an expression of status, identity and territoriality. Appearances of the kites in rock art found in Jordan suggests they had an important place within the symbolic and ritual spheres of Neolithic peoples in the region.
From the design of the kite heads to the careful runs of guiding walls over long distances, these structures contrast markedly in scale with any other evidence of architecture from the early Holocene period. The researchers suggest that the builders of these kites dwelt in temporary structures made from organic materials that have left no trace visible on current satellite imagery data.
Desert kite research is a very active field just now – Michael and colleagues explore a significant extension to their distribution pattern, which has major implications for our understanding of the relationship of the kite builders with new mobile pastoralists and the occupation of the region.
Bill Finlayson, Director of EAMENA and Professor of Prehistoric Archaeology at the University of Oxford
These new sites suggest a previously unknown level of connection right across northern Arabia at the time they were built. They raise exciting questions about who built these structures, who the hunted game were intended to feed, and how the people were able to not only survive, but also invest in these monumental structures.
In the context of this new connectedness, the distribution of the star-shaped kites now provides the first direct evidence of contact through, rather than around, the Nafud desert. This underlines the importance areas that are now desert had under more favourable climatic conditions in enabling the movement of humans and wildlife. It is thought the kites were built during a wetter, greener climatic period known as the Holocene Humid Period (between around 9000 and 4000 BCE).
The largest number of kites were built on the Al Labbah plateau in the Nafud desert, where the absence of later Bronze Age burial monuments suggests that a shift into a drier period meant some of these areas became too marginal to support the communities once using these landscapes, with game species also potentially displaced by climate change.
Whether the patterns of kite construction over space and time represent the movement of ideas or people, or even the direction of that movement, remain questions to be answered.
The project, supported by the Arcadia Fund, is now extending its survey work across these now arid zones to further develop our understanding of these landscapes and the effect of climate change.
The study Following the herds? A new distribution of hunting kites in Southwest Asia is published in The Holocene.
All MENA countries, derived from the XIX and early XX centuries, acquired this capability when policing their citizens, identifying any person protesting their government without due process. The same applies to interstate relations where transboundary resources and interests of any kind envenom and more often inflame situations. So, at this conjecture, is it not the opportune time to at least try unlocking a Peace Ministry in the Middle East?
Unlocking Peace Ministry in the Middle East: Announcing the Middle East Consultation 2022
Everything is affected whenever peace is missing. Absolutely everything! Conflict has a way of harming all areas of the human experience. We all know too well the pain and confusion undermining peace throughout our nations, our communities, and our own souls in regrettable ways. It disorients and forces us to grapple with the seemingly overwhelming gravity of sin and the depth of its consequences. For this reason, God really, really cares about peace.
Seeking peace is essential to God’s story for humanity. Scripture demonstrates the extent to which conflict infects a fallen world while also declaring the length God goes for the sake of peace. This didn’t happen without sacrifice; Jesus Christ endured the extreme weight of conflict as he hung on the cross. And it was on this journey to the cross that he shared eternal words with his disciples: “Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid” (John 14:27). This is a perplexing type of comfort. Jesus is perfectly aware that our hearts will face trouble and fear in an uncertain world, but he assures us that the only kind of peace that can suffice is an otherworldly peace. Because of this, we have hope amid the storms of strife.
It can feel like the Middle East invents ever creative ways to undermine peace as people across the region deal with struggling societies, mounting insecurities, dirty politics, violent factionalism, destructive ideologies, and wave after wave of crisis. The problems fill headlines and reports throughout ceaseless cycles of bad news. Residents struggle through chronic frustration and disillusion, and growing numbers are joining a migration outflow seeking better fortunes in new locations.
Christ followers across the Middle East face their own flavors of conflict. Egypt encounters layers of challenges as churches and Christian groups serve amid rapidly changing times. In Algeria churches struggle to forge faith communities against the grain of a suppressive government. Christians of Iraq continue to navigate decades-long strife while trying to nurture one another and serve their neighbors. In Palestine, occupation and oppression hinder the most basic areas of human life and fuel hardships of many kinds. Sudan’s believers are dealing with rapidly changing political situations after years of regime change and upheaval. And in Lebanon, new layers of crisis pile upon old, unresolved conflicts to destabilize a state and its people. Unfortunately, these are only brief samples of the range of conflict raging across the region. It can all seem so overwhelming, and in the darkest moments cries go out, “Why, Lord, do you stand far off? Why do you hide yourself in times of trouble?” (Psalms 10:1).
Though it doesn’t come easily, we must insist on recognizing the profound ways God’s people can and do faithfully minister peace amid challenging situations. Churches, organizations, and individuals of faith are ready vessels for extending Christ’s peace; they possess the potential by the Spirit to alter situations and write new stories for people and places. Is this not what it means to take hold of the peace that Christ leaves? This among the many questions the Middle East Consultation 2022 aims to ask on September 21-23 during Peace I Leave with You: Theories and Practices for Peace Ministry in the Middle East.
Practicing effective peace ministry requires us to imagine peace in ways that conform our thoughts and attitudes to the person of Christ in service of others. Biblically, peace ministry can be understood as the work of unlocking human potential by moving people, communities, and nations into healthier dynamics of shared life. Such outreach proceeds from deep convictions that the gospel is a holistic response to any situation where sin inflicts strife, oppression, hatred, and mistrust- everything antithetical to the restorative work of God.
Paradigms for peace ministry can help us recognize how peace involves multidimensional expressions (peacekeeping, peacemaking, and peacebuilding) working across levels of the human experience, including the personal, group, and national. The following grid, which MEC 2022 will adopt as a basic working framework, helps conceptualize this dynamic:
Such a framework is helpful, but it certainly cannot convey the complexity of engaging conflict. There are no simple explanations or quick solutions to the problems plaguing the Middle East. Each unique context in the region carries assorted variables that require us to ask a proper set of questions. Worldly logic may say peace is an elusive dream or unattainable ideal, but authentic faith in Christ compels us to take hold of the gospel’s promises of peace as we seek to discover how God is active and alive in the world. Our eschatological hope for the future moves us to action as we relish the words of Isaiah 9:7: There will be no end to the increase of His government or of peace on the throne of David and over his kingdom, to establish it and to uphold it with justice and righteousness from then on and forevermore.
God is working through conflict for redemptive purposes, and everyone has a role to play in this. This means embracing the invitation to partner with God in living out Christ-honoring works of peace and continually exploring new ways to think about the theories and practices of peace ministry.
