French-Lebanese architect seeks pro-climate construction transformation
Lina Ghotmeh has pegged her career on sustainable construction.
The French-Lebanese architect wants to see her industry transformed by drastically reducing the use of concrete — a major CO2 contributor — using more local materials and reusing existing buildings and materials.
“We need to change our value system,” the 42-year-old told AFP last month.
The aim is to reduce the carbon footprint of the construction industry and create buildings that can better resist the impacts of climate change.
But it’s not an easy battle.
The industry accounts for almost 40 percent of global greenhouse gas emissions, according to the United Nations.
Ghotmeh, who designed the Estonian National Museum and taught at Yale University, doesn’t advocate for fewer buildings — she knows that’s an unrealistic goal in a world with a growing population.
“That would be like saying ‘stop eating,'” she said.
– ‘Don’t demolish’ –
Instead, we should “keep what already exists, don’t demolish,” but refurbish and retrofit old buildings in a sustainable way where possible.
Building a new detached house consumes 40 times more resources than renovating an existing property, and for a new apartment complex that rises to 80 times more, according to the French Agency for Ecological Transition (Ademe).
And then there’s concrete, the main material in so many modern buildings and perhaps the most challenging to move away from.
“We must drastically reduce the use of concrete”, she said, insisting it should only be used for essential purposes, such as foundations and building in earthquake-prone areas.
Some 14 billion cubic metres of concrete are used every year, according to the Global Cement and Concrete Association.
It emits more CO2 than the aviation industry, largely because of the intense heat required to make it.
Alternatives to concrete already exist, such as stone, or making cement — a component of concrete — from calcium carbonate. There are also pushes for low-carbon cement made from iron and steel industry waste.
– Beirut inspiration –
Building more sustainably often comes with a higher price tag — it costs more to double or triple glaze windows and properly insulate a house — but the long-term payoff is lower energy costs.
For Ghotmeh, it’s an imperative investment in our future.
It was her birthplace of Beirut that inspired her to become an architect, spurring a desire to rebuild the so-called “collapsed city” ravaged by war.
In 2020, she completed the “Stone Garden” apartment tower in the city, built with concrete covered with a combed coating, a technique often used by local craftsmen. She used concrete in the construction because of earthquake risks.
The building was strong enough to survive the port explosion in 2020 that destroyed a large part of the city.
And the city continues to inspire her today, even when it comes to climate sustainability.
“Since there is practically only an hour of electricity per day, all the buildings have solar panels now. There is a kind of energy independence which is beginning to take place, by force,” she said.
“Does it take a catastrophe like the one in Lebanon to make this transition?”
The COP27 delivered partial success in an agreement on a fund for those vulnerable countries; however, it still needs to provide an understanding of the most basic requirements for stopping the current climate breakdown. That is mainly to slash the burning of fossil fuels as promptly as possible. In the meantime, life carries on. Like in the story that follows, it is not building better with less at this conjecture and not about decarbonising all active ingredients but, like Azerbaijan sharing investment plans within the concept of ‘smart’ cities and villages.
Azerbaijan shares investment plans within concept of ‘smart’ cities, villages
BAKU, Azerbaijan, November 21. Azerbaijan cooperates with the world’s leading companies in the building of ‘smart’ cities and villages, Azerbaijani Minister of Digital Development and Transport Rashad Nabiyev said on November 21 during an international conference on ‘smart’ cities and villages, being held in Baku, Trend reports.
According to Nabiyev, the concepts of ‘smart’ cities and villages contribute to the efficient use of water and other natural resources.
“In the next five years, $2.5 trillion will be invested in these concepts. Azerbaijan has been working in this direction since 2020. Our ministry has studied the experience of leading countries when elaborating on the concepts. Within the framework of the ‘Online Azerbaijan’ concept, large-scale work is being carried out to integrate state systems, switch to ‘cloud’ technologies and other work,” the minister noted.
Besides, Nabiyev noted that the effectiveness of the concept of ‘smart’ cities and villages may differ depending on the region.
“When implementing these projects, we take into account the factor of development of local companies and their localization,” he said.
The minister pointed out that over the past two years, 472,000 households in Azerbaijan have been provided with fiber-optic communication, and by 2024 even the most remote villages will be provided with it.
Speaking about the development of these projects, Nabiyev said that more attention should be paid to ensuring the security of information systems.
“In the next three years, 932 highly qualified specialists in the field of cybersecurity will be trained in Azerbaijan,” he added.
Is digital trust the key to sustainable planning? wondered Nicole Bennetts, Senior Urban and Regional Planner in an ARUP blog. The answer follows.
Is digital trust the key to sustainable planning?
Our growth challenges in cities globally are becoming more complex. Now more than ever, we need new solutions and creativity to help us shape more resilient and sustainable cities in the future.
For the first time in history, we have access to dynamic urban data to understand people’s collective behaviours in real time. If used, this expansive evidence base can help planners, designers, and decision-makers make more informed decisions about the future of our cities.
However, the timing dilemma is an obstacle in harnessing this data. While urban environments typically develop every 50 years, technology moves more rapidly, significantly improving every five years, creating a disparity between urban planning and urban living.
So how does the planning industry keep pace with digital technology to create sustainable outcomes? One way is to improve our relationship with the digital world and put trust and confidence in digital tools and innovative solutions.
While urban environments typically develop every 50 years, technology moves more rapidly, significantly improving every five years, creating a disparity between urban planning and urban living.
While urban environments typically develop every 50 years, technology moves more rapidly, significantly improving every five years, creating a disparity between urban planning and urban living.
Why should planners trust data and digital?
Our cities are where urban planning and living come together. They are a super ‘neural network’ of interrelated systems. To create intelligent, responsive cities, urban development must embrace new possibilities using data and the internet of things (IoT).
Technology and data have never been more available. As a result, urban planning has a massive opportunity to unleash its full potential by investing more time and resources into harnessing data and digital planning.
Tools like the ‘digital twin’ are likely to become an indispensable part of future ‘urban infrastructure’, enabling the seamless integration of the ‘physical’ and ‘digital’ worlds and redefining how we plan.
Similarly, digital master planning is a framework to test thousands of options based on various variables and parameters to test failure, resilience, adaptative pathways, optimal living conditions, human health and welling, energy efficiency and more.
The planning industry must adapt to this changing paradigm, by matching the efforts and confidence invested in building the cloud system and IoT coverage, or risk being left behind.

How Arup planners are using the power of digital
Projects worldwide show the value and credibility of digital tools to create growth and provide sustainable outcomes.
Cities urban tree canopy is a critical component of green infrastructure providing comfortable environments and reducing heat. Arup’s leading Urban tree canopy analysis used is a study for the City of Gold Coast, which uses a computer algorithm to determine the percentage of vegetation cover over different time intervals to show canopy changes.
Terrain is Arup’s bespoke artificial intelligence and land use analysis tool. It harnesses the power of data analytics, machine learning and automation to accurately digest large quantities of data and satellite imagery. Using this tool, we calculated seven cities’ sponginess by measuring the green and blue infrastructure areas to understand how cities can better use this infrastructure to face increasing threats from climate change – including heavy rainfall and extreme heat events.
Another Arup tool is the City Algorithm Tool (CAT) which tests hundreds of growth scenarios using different development and community value parameters to determine optimal outcomes for urban living. For example, Smakkelaarsveld in the Netherlands used algorithms to optimise the scheme design against multiple KPIs, including sustainability and environmental objectives.
Similarly, digital master planning can test site and precinct options based on various variables and parameters to test failure, resilience, adaptative pathways and optimal living conditions.
The last example, solar analysis helps test hundreds of layouts and orientations to achieve optimal living conditions and thermal comfort. For example, for Mahindra World City Jaipur, we used solar assessment tools to determine the optimal orientation for the plots and streets to provide thermal comfort in a hot climate.
Small risks, great rewards
Trust in the planning process is the foundation for our cities to take the best path to sustainable growth. Taking small, calculated risks in improving our digital capabilities now can lead to great rewards for our cities.
Taking small, calculated risks in improving our digital capabilities now can lead to great rewards for our cities.
Speed and efficiency, automating tedious and repetitive tasks and allowing more design and collaboration time.
Test 3D scenarios, assessing hundreds or thousands of options during the planning process against agreed parameters or criteria.
Facilitate approval process, comparing design scenarios with consented planning schemes and existing site conditions for faster agreement on key issues.
Identify client priorities; testing many possibilities can help identify what is most important.
Improve participatory design; with more data, we can understand community needs and improve community engagement.
As of October 2021, 44 countries were reported to have their own national AI strategic plans, showing their willingness to forge ahead in the global AI race. These include emerging economies like China and India, which are leading the way in building national AI plans within the developing world.
Oxford Insights, a consultancy firm that advises organisations and governments on matters relating to digital transformation, has ranked the preparedness of 160 countries across the world when it comes to using AI in public services. The US ranks first in their 2021 Government AI Readiness Index, followed by Singapore and the UK.
Notably, the lowest-scoring regions in this index include much of the developing world, such as sub-Saharan Africa, the Carribean and Latin America, as well as some central and south Asian countries.
The developed world has an inevitable edge in making rapid progress in the AI revolution. With greater economic capacity, these wealthier countries are naturally best positioned to make large investments in the research and development needed for creating modern AI models.
In contrast, developing countries often have more urgent priorities, such as education, sanitation, healthcare and feeding the population, which override any significant investment in digital transformation. In this climate, AI could widen the digital divide that already exists between developed and developing countries.
The hidden costs of modern AI
AI is traditionally defined as “the science and engineering of making intelligent machines”. To solve problems and perform tasks, AI models generally look at past information and learn rules for making predictions based on unique patterns in the data.
AI is a broad term, comprising two main areas – machine learning and deep learning. While machine learning tends to be suitable when learning from smaller, well-organised datasets, deep learning algorithms are more suited to complex, real-world problems – for example, predicting respiratory diseases using chest X-ray images.
Crucially, neural networks are data hungry, often requiring millions of examples to learn how to perform a new task well. This means they require a complex infrastructure of data storage and modern computing hardware, compared to simpler machine learning models. Such large-scale computing infrastructure is generally unaffordable for developing nations.
Beyond the hefty price tag, another issue that disproportionately affects developing countries is the growing toll this kind of AI takes on the environment. For example, a contemporary neural network costs upwards of US$150,000 to train, and will create around 650kg of carbon emissions during training (comparable to a trans-American flight). Training a more advanced model can lead to roughly five times the total carbon emissions generated by an average car during its entire lifetime.
Developed countries have historically been the leading contributors to rising carbon emissions, but the burden of such emissions unfortunately lands most heavily on developing nations. The global south generally suffers disproportionate environmental crises, such as extreme weather, droughts, floods and pollution, in part because of its limited capacity to invest in climate action.
Developing countries also benefit the least from the advances in AI and all the good it can bring – including building resilience against natural disasters.
Using AI for good
While the developed world is making rapid technological progress, the developing world seems to be underrepresented in the AI revolution. And beyond inequitable growth, the developing world is likely bearing the brunt of the environmental consequences that modern AI models, mostly deployed in the developed world, create.
But it’s not all bad news. According to a 2020 study, AI can help achieve 79% of the targets within the sustainable development goals. For example, AI could be used to measure and predict the presence of contamination in water supplies, thereby improving water quality monitoring processes. This in turn could increase access to clean water in developing countries.
The benefits of AI in the global south could be vast – from improving sanitation to helping with education, to providing better medical care. These incremental changes could have significant flow-on effects. For example, improved sanitation and health services in developing countries could help avert outbreaks of disease.
But if we want to achieve the true value of “good AI”, equitable participation in the development and use of the technology is essential. This means the developed world needs to provide greater financial and technological support to the developing world in the AI revolution. This support will need to be more than short term, but it will create significant and lasting benefits for all.
Here is Gilgamesh Nabeel in MENA Region Digital Transformation Can Create More Jobs as per a recent report that says so.

Lack of digital infrastructure contributes to high rates of youth unemployment in the MENA region, a new report says.
The report, “COVID-19 and Internet Accessibility in the MENA Region”, was published in mid-December by the U.S.-based Woodrow Wilson International Center for Scholars. It assesses the readiness of the MENA region countries to shift employment online, both in terms of Internet availability and digital literacy among the populace.
Its authors, Alexander Farley and Manuel Langendorf, argue that increasing internet accessibility and investing in digital infrastructure development can help governments’ efforts to form a digitally-enabled economic recovery strategy.
While the MENA region is projected to have 160 million potential digital users by 2025, the paper draws a bleak image of its internet infrastructure and accessibility.
Last year, 34 percent of the population in Arab states was not using the Internet, according to ITU data. In 2019, the GSMA, which represent the interests of mobile network operators worldwide, found that almost half the people in countries such as Egypt and Lebanon, which have a mobile broadband network, are not using the Internet. Around 60 million people in the MENA region were not covered by a mobile network.
“Studies have shown that broadband development leads to increased GDP and has a positive impact on employment in the short term – part of the picture are newly created jobs to build new digital infrastructure,”
Manuel Langendorf A researcher focusing on digital transformation in the MENA region and co-author of the report
Furthermore, with the exception of the UAE and Qatar, which cover about 80 percent of households directly with fiber, only nine out of 100 inhabitants in Arab states used fixed broadband subscriptions, the second-lowest rate of all world regions, after Africa.
The paper says the development of digital infrastructure overall continues to lag behind the rest of the world. This holds back the region’s digital transformation and deprives it of the benefits of investment in improving national core networks.
Digital Infrastructure Development Boosts Jobs
Overall, unemployment in the MENA region stood at 11.6 percent with the “the low-skilled, the young, women, and migrant workers were affected the most” by the pandemic, the report says. In 2019, youth unemployment was over 25 percent, with further decline in youth employment by an additional 10 percent in 2020.
Manuel Langendorf, a researcher focusing on digital transformation in the MENA region and co-author of the report, argued that proper investment in digital infrastructure can help government confront unemployment.
“Digital transformation is not a silver bullet to solve the MENA region’s protracted unemployment problem, but it can create new job opportunities, especially for the large young and relatively tech-savvy population,” Langendorf told Al-Fanar Media.
“Studies have shown that broadband development leads to increased GDP and has a positive impact on employment in the short term – part of the picture are newly created jobs to build new digital infrastructure,” he added.
While the longer term effects seem less clear, Langendorf thinks a country-wide improvement to digital infrastructure can bring new economic opportunities, including for disadvantaged populations and rural areas.
“These include the expansion of remote working, as an employee or freelance worker, and also allows workers to search for employment opportunities more widely,” he added. “An improved digital infrastructure also opens up new job opportunities in online education.”
Citing the installation of ten submarine internet cables between Europe and Africa, he said: “We found a significant and large relative increase in the employment rate in connected areas when fast internet becomes available.”
Do We Need More IT Graduates?
In the Internet era, when many traditional jobs might disappear, students see IT-related courses as a route to secure jobs.
However, the report highlighted that some countries, like Jordan, graduate around 5,000 students in IT-related fields each year, yet less than 2,000 are hired. Still, some see an opportunity for ICT graduates from the region to fill the shortage of skilled IT workers in Western countries.
“University curricula in most MENA countries are slow to update, thus creating a situation where many fresh graduates hold a diploma but are not ready to start working in the IT sector as their knowledge is outdated,” he wrote to Al-Fanar Media.
“Nevertheless, many MENA startups have had great success in the past years. In 2021, MENA-based startups raised close to $3 billion, a new record for the region.”
He called on the education and the private sectors to collaborate to improve the university-job pipeline and close the skills gap. “Both sides should make sure that the latest IT knowledge is integrated into curricula and set up internship opportunities for students and graduates,” he said. “Beyond universities, the private sector and educational institutions can hold more workshops to bring people up to speed.”
The report also identified management skills as one of the biggest challenges to expanding potential of IT in the MENA region. “The lack of management skills affects the scalability of projects and businesses that can make use of the surplus of advanced IT skills,” said Farley.
Moreover, the authors said the MENA region lacks truly innovative IT ventures, and is focused instead on adapting ideas created elsewhere.
“In this context, the region is often described as a consumer rather than a creator of technology,” said Farley. “Nevertheless, many MENA startups have had great success in the past years. In 2021, MENA-based startups raised close to $3 billion, a new record for the region.”
Fruitful Digital Transformation Tips
Governments and other stakeholders need to ensure that the expansion of digital infrastructure focuses not just on connectivity (areas covered by Internet), but accessibility, the authors went on.
“Is using the Internet affordable? Do people have access to devices to use the Internet?” wondered Langendorf. “Mobile industry body GSMA estimated those living in areas with a mobile broadband network but not using mobile internet increased from 41 percent to 48 percent between 2014 and 2020.”
To enable investments in digital infrastructure to tackle unemployment, Langendorf calls on governments to support entrepreneurship. “They need to facilitate starting a business and obtaining loans, and decriminalizing bankruptcy,” he said.
“Besides, they should enable cross-border trade and the movement of skilled people between countries.”
