As the world struggles with COVID-19, the challenges of climate change and wider environmental problems loom large. It is clear that the economic response to the impact of COVID-19 must benefit the environment while plans to address climate change and environmental issues must benefit the economy and society. The only way these twin imperatives can be met is through a green revolution that transcends our economy and society.
This was our task when we both chaired the first Intelligent Planning Consultative Forum that was established by Environment Minister Aaron Farrugia. The aim of the forum was to bring together all stakeholders involved in the planning and construction sectors to start coming up with ways in which we can transform and transition planning and construction which is smart, green and sustainable.
The result of this forum and the discussions we led is the green policy document on green walls and roofs together with the recently-launched scheme by the government to incentivise such improvements.
This incentive scheme should be seen as the first step towards having greener and more sustainable buildings. The benefits of such interventions are major given that they result in low energy consumption and decreased carbon emissions while mitigating the effects of roof flooding. This happens as the green infrastructure, walls or roofs, acts as a protective layer for buildings, absorbing heat and excess water.
Additionally, the utilisation of local fauna in such projects would create various pollination havens across the island, helping to restore natural biodiversity – a key aim of the EU’s 2030 biodiversity strategy. The utilisation of Maltese fauna could have the additional benefit of requiring minimal maintenance and reduce the consumption of water.
Such initiatives also have macro effects including the creation of additional value-adding activities and green jobs. Together with other initiatives and incentives, the demand for such products could even help kickstart a whole new industry focused on green construction.One of Malta’s biggest opportunities in the Green Deal is greening the construction sector
In fact, one of Malta’s biggest opportunities in the Green Deal is greening the construction sector which remains a significant contributor to economic growth. The EU recently launched the New European Bauhaus and, in a statement, European Commission president Ursula von der Leyen said that “the New European Bauhaus is about how we live better together after the pandemic while respecting the planet and protecting our environment. It is about empowering those who have the solutions to the climate crisis, matching sustainability with style”.
This is something we believe can truly support the country in its next phase of design, planning and construction. Malta and Europe have a number of common challenges. Whereas the original Bauhaus was focused on new designs, the biggest challenge we face is of renovation, regeneration and retrofitting.
We are surrounded by buildings and infrastructures, home to both embodied carbon and embedded histories. A design and architecture for this problem requires a quite different sensibility. It implies a refining in place, understanding repair and retrofit cultures and developing new logics predicated on care and maintenance.
These approaches, in line with the EU Recovery Strategy, necessitate new ways of unleashing the societal value latent in people and place. Producing anew in this way is far more challenging than simply making new things –although new things will emerge.
Malta has a unique potential in this and, if leveraged properly, we can truly kick-start a green revolution in our planning and building industries. We are confident that the new phase of the Intelligent Planning Consultative Forum will look into this and, together with the environment minister, a new era of Malta’s planning and construction industry can commence, one that is smart, green and sustainable.
The green wall and roof initiative and support scheme is a step in the right direction.

The Massachusetts Institute of Technology asking Why the Mediterranean is a climate change hotspot came up with A new analysis uncovers the basis of the severe rainfall declines predicted by many models.
17 June 2020
Although global climate models vary in many ways, they agree on this: The Mediterranean region will be significantly drier in coming decades, potentially seeing 40 percent less precipitation during the winter rainy season.
An analysis by researchers at MIT has now found the underlying mechanisms that explain the anomalous effects in this region, especially in the Middle East and in northwest Africa. The analysis could help refine the models and add certainty to their projections, which have significant implications for the management of water resources and agriculture in the region.
The study, published last week in the Journal of Climate, was carried out by MIT graduate student Alexandre Tuel and professor of civil and environmental engineering Elfatih Eltahir.
The different global circulation models of the Earth’s changing climate agree that temperatures virtually everywhere will increase, and in most places so will rainfall, in part because warmer air can carry more water vapor. However, “There is one major exception, and that is the Mediterranean area,” Eltahir says, which shows the greatest decline of projected rainfall of any landmass on Earth.
“With all their differences, the models all seem to agree that this is going to happen,” he says, although they differ on the amount of the decline, ranging from 10 percent to 60 percent. But nobody had previously been able to explain why.
Tuel and Eltahir found that this projected drying of the Mediterranean region is a result of the confluence of two different effects of a warming climate: a change in the dynamics of upper atmosphere circulation and a reduction in the temperature difference between land and sea. Neither factor by itself would be sufficient to account for the anomalous reduction in rainfall, but in combination the two phenomena can fully account for the unique drying trend seen in the models.
The first effect is a large-scale phenomenon, related to powerful high-altitude winds called the midlatitude jet stream, which drive a strong, steady west-to-east weather pattern across Europe, Asia, and North America. Tuel says the models show that “one of the robust things that happens with climate change is that as you increase the global temperature, you’re going to increase the strength of these midlatitude jets.”
But in the Northern Hemisphere, those winds run into obstacles, with mountain ranges including the Rockies, Alps, and Himalayas, and these collectively impart a kind of wave pattern onto this steady circulation, resulting in alternating zones of higher and lower air pressure. High pressure is associated with clear, dry air, and low pressure with wetter air and storm systems. But as the air gets warmer, this wave pattern gets altered.
“It just happened that the geography of where the Mediterranean is, and where the mountains are, impacts the pattern of air flow high in the atmosphere in a way that creates a high pressure area over the Mediterranean,” Tuel explains. That high-pressure area creates a dry zone with little precipitation.
However, that effect alone can’t account for the projected Mediterranean drying. That requires the addition of a second mechanism, the reduction of the temperature difference between land and sea. That difference, which helps to drive winds, will also be greatly reduced by climate change, because the land is warming up much faster than the seas.
“What’s really different about the Mediterranean compared to other regions is the geography,” Tuel says. “Basically, you have a big sea enclosed by continents, which doesn’t really occur anywhere else in the world.” While models show the surrounding landmasses warming by 3 to 4 degrees Celsius over the coming century, the sea itself will only warm by about 2 degrees or so. “Basically, the difference between the water and the land becomes a smaller with time,” he says.
That, in turn, amplifies the pressure differential, adding to the high-pressure area that drives a clockwise circulation pattern of winds surrounding the Mediterranean basin. And because of the specifics of local topography, projections show the two areas hardest hit by the drying trend will be the northwest Africa, including Morocco, and the eastern Mediterranean region, including Turkey and the Levant.
That trend is not just a projection, but has already become apparent in recent climate trends across the Middle East and western North Africa, the researchers say. “These are areas where we already detect declines in precipitation,” Eltahir says. It’s possible that these rainfall declines in an already parched region may even have contributed to the political unrest in the region, he says.
“We document from the observed record of precipitation that this eastern part has already experienced a significant decline of precipitation,” Eltahir says. The fact that the underlying physical processes are now understood will help to ensure that these projections should be taken seriously by planners in the region, he says. It will provide much greater confidence, he says, by enabling them “to understand the exact mechanisms by which that change is going to happen.”
Eltahir has been working with government agencies in Morocco to help them translate this information into concrete planning. “We are trying to take these projections and see what would be the impacts on availability of water,” he says. “That potentially will have a lot of impact on how Morocco plans its water resources, and also how they could develop technologies that could help them alleviate those impacts through better management of water at the field scale, or maybe through precision agriculture using higher technology.”
The work was supported by the collaborative research program between Université Mohamed VI Polytechnique in Morocco and MIT.
Erosion of sandy beaches will endanger wildlife, cause massive losses in coastal cities in the world. Mohammed El-Said, in his Egypt related article titled Egypt to lose 1000 km of sandy coasts due to erosion: Study is by any means not exaggerating the potential impact of climate change on Egypt. The country’s habitable space is very limited to 5 per cent. The rest of the land is uninhabitable desert. The population, therefore, concentrated around the narrow Nile Valley and Nile Delta, with some smaller numbers along the Mediterranean and the Red Sea coasts would want to preserve as much as possible of the seafront.
The world’s beaches represent an interface between land and water, and provide protection for coasts from marine storms and hurricanes, but a new study by the European Commission’s Joint Research Centre indicates that without mitigating the effects of climate change and adapting to it, half of the world’s beaches will be vulnerable to erosion by the end of the century.
Erosion of sandy beaches will endanger wildlife and may cause heavy losses in coastal cities that no longer have buffer zones to protect them from rising sea levels and severe storms. In addition, coastal erosion increases the cost of governmental measures to mitigate the effects of climate change.
In the study published last week in the journal Nature Climate Change, researchers expect erosion to destroy 36,097 km, or 13.6% of sandy coasts around the world, including the Egyptian coast, within 30 years. The situation is expected to worsen in the second half of the century as 9,561 km, equivalent to 25.7% of the world’s beaches are estimated to be eroded.
The study provides forecasts of the shoreline’s shape between the years 2050 and 2100. It links changes in the shoreline directly to climate change based on the concentration of greenhouse gases according to the Representative Concentration Pathway (RCP) approved by the Intergovernmental Panel on Climate Change (IPCC). Thus, the study aims to calculate shoreline changes globally based on the ratio of greenhouse gases in the atmosphere.
In the latest report of the IPCC in 2019, scientists studied the greenhouse gas concentration pathway and expect that, by 2100, if countries in the world do not comply with the terms of the Paris climate agreement, average global sea levels will rise between 61 centimeters to about one meter.
Researchers relied on climate data, models, 82 years’ worth of sea level monitoring, and 35 years of beach satellite imaging. They also simulated more than 100m storms and measured their global coastal erosion.
Based on the RCP of greenhouse gases, the study assumes two scenarios for melting ice surfaces. According to the first scenario, if the world continues to emit carbon at the current rate, sea levels will rise by about 80 cm, which means the coastline will decrease by 128.1 meters, and threatens to sink 131,745 km of beaches.
According to the most optimistic scenarios, sea levels will only rise by 50 cm by 2100, and the average coastline retreat will be 86.4 meters if governments adhere to international agreements to reduce emissions and reduce carbon dependence. According to the results of the study, up to 63% of the world’s low coastal areas will be threatened by flooding due to sea level rise and severe storms.
“Climate change will exacerbate the effects of coastal erosion processes, which threatens densely populated areas,” said Michalis Vousdoukas, a researcher at the European Commission’s Research Centre and lead author of the study.
He added that in the best scenarios, Egypt will lose between 35.1% to 50.5% of its sandy beaches due to erosion, which means the erosion of about 1,000 km of Egyptian sandy beaches. The percentage is likely to be even higher in countries like Saudi Arabia and Libya.
Hisham Elsafti, a coastal engineering consultant, and instructor in coastal engineering at Braunschweig Technical University in Germany, explained that according to the study’s expectations, the coasts of the Nile Delta will retreat by more than half a kilometer at the end of the century due to geological and hydromorphological factors.
But Jeffrey S. Kargel, a senior research scientist at the University of Arizona, believes that although the methodology of the study is good and its conclusions are valid, it did not take into account some detailed changes. These changes include the sediment supply and the increase in the production and transport of sand and silt due to the increased melting glaciers, increased surface runoff of corrosion and more sediment supply from expanded agricultural areas, increased sediment supply from dam construction, and reduced sediment transport due to dams in many parts of the world.
Kargel explained that the melting glaciers do not directly affect Egypt, but affect places like Greenland and Alaska. “Construction of dams is the most important for Egypt due to the construction of the High Dam in Aswan, and then there will be a giant reservoir for the huge dam in Ethiopia,” he said.
He added that “when the silt is blocked by reservoirs, this will be an obstacle to the construction of the delta areas, and thus the delta will drop and seawater will submerge its coast with its cities and villages, which will represent a major problem for Egypt.” But he believes that the Egyptian Delta, despite the problems it faces, is “lucky” because it is not subject to hurricanes.
A previous study by the American Geological Society, published in May 2017, indicated that Egypt is one of the countries most affected by climate change, and that between 20 to 40 km of the coast of the Nile River Delta will be flooded with seawater by the end of the century, due to Sea level rise.
Vousdoukas added that the UK expects to lose 27.7% of its sandy beaches, according to the best estimates, and 43.7% according to worst case scenarios. Australia is also expected to be the most affected, as about 15,000 km of its beaches are at risk, followed by Canada as one of the most affected countries, then Chile, Mexico, China, and the United States. It is also expected that more than 680 million Indian citizens living in the low-lying coastal region will be affected by the coastal erosion and climate change.
Glimmer of hope
“The study provides first-of-its-kind forecasts regarding sand beach erosion, taking into account human interventions as well as the effects of climate change and natural factors,” said Vousdoukas. The researcher explained that there is still a glimmer of hope as it can reduce greenhouse gas emissions to prevent 40% of the coastline retreat, but this requires an international commitment to the Paris Climate Agreement and related protocols, and requires some coastal protection measures to protect populated areas.
Elsafti, however, believes that Egypt should work on two main axes to avoid the negative effects of climate change and protect the beaches. The first is the effective contribution to calls to reduce greenhouse gas emissions, and asking major industrial countries responsible for the problem to contribute more effectively to solving the problem by increasing contributions in initiatives such as the Green Climate Fund, which is already participating in funding studies and work to protect Egyptian beaches.
“The second axis is a scientific axis, as Egypt must increase the funding of scientific studies that cross the disciplines required to find engineering solutions suitable for the Egyptian environment and prepare to change the planning of cities and coastal areas and their uses to adapt to the effects of climate change,” Elsafti said.
According to UNCHR, those fleeing their own countries for fear of persecution travel collectively around two billion kilometres per year to reach a safe haven. To honour their resilience and determination and to remind us of the long and tortuous journeys they are forced to make on their way to safety, the United Nations High Commissioner for Refugees (UNHCR) has launched the www.stepwithrefugees.org campaign to mark 2019 World Refugee Day.
The number of migrant and refugee school-age children around the world has grown by 26% since 2000. Eight years on from the beginning of the Syrian conflict, a new paper released today and at an event in the Netherlands looks at the importance of making sure that education systems are set up to address the trauma that many of these children face before, and during their journeys to new countries. In particular, teachers need better training to provide psychosocial support to these children, including through social and emotional learning.
In Germany, about one-third of refugee children suffer from mental illness, and one-fifth suffer from post-traumatic stress disorder. Unaccompanied minors are particularly vulnerable. One third of 160 unaccompanied asylum seeking children in Norway from Afghanistan, the Islamic Republic of Iran and Somalia suffered from post-traumatic stress disorder. Among 166 unaccompanied refugee children and adolescents in Belgium, 37-47% had ‘severe or very severe’ symptoms of anxiety, depression and PTSD.
Rates of trauma among the displaced in low and middle income countries are also high. For instance, 75% of 331 internally displaced children in camps in southern Darfur in Sudan met diagnostic criteria for post-traumatic stress disorder, and 38% had depression.
In the absence of health centres, schools can play a key role in restoring a sense of stability. Teachers are not and should never be leant on as mental health specialists, but they can be a crucial source of support for children suffering from trauma if they’re given the right training. But they need basic knowledge about trauma symptoms and providing help to students, which many do not have. NGOs, including the International Rescue Committee, iACT, and Plan International, are training teachers to face this challenge through their programmes, but their reach is not enough.
In Germany, the majority of teachers and day-care workers said that they did not feel properly prepared to address the needs of refugee children. In the Netherlands, 20% of teachers with more than 18 years of experience working in mainstream schools reported that they experienced a high degree of difficulty dealing with students with trauma. The vast majority of these teachers (89%) encountered at least one student with trauma in their work. A review of early childhood care and education facilities for refugee children in Europe and North America found that, although many programmes recognized the importance of providing trauma-informed care, appropriate training and resources were ‘almost universally lacking’.
The paper shows the importance of social and emotional learning, as an approach to psychosocial support which targets skills, such as resilience, to manage stress, and is often rolled out through interactive, group-based discussions or role play. It shows the importance of this approach for less acute situations but emphasizes that for more challenging cases trained specialists are needed.
It is also important to involve parents in social and emotional learning so that activities can continue at home. One programme in Chicago looked at addressing symptoms of depression among Mexican immigrant women and primary school children with in- and after- school programmes and home visits, for instance, and improved school work, child mental health and family communication.
Learning environments must be safe, nurturing and responsive.
Teachers working with migrant and refugee students who have suffered trauma face particular hardships and need training to cope with challenges in the classroom.
Psychosocial interventions require cooperation between education, health and social protection services.
Social and emotional learning interventions need to be culturally sensitive and adapted to context. They should be delivered through extra-curricular activities as well.
Community and parental involvement should not be neglected.
There seems to be some race between the USA and Europe with France’s TOTAL that recently signed with Algeria a contract for a polypropylene plant in the country. There were afterwards two days of public demonstrations in different localities close to the country’s oil bases in the South. Locals were out and about shouting out their frustrations of possibly turning into passive witnesses to fracking within walking distance to their familiar and naturally unkind environment. Far from being left behind, Exxon Mobil also signed a gas contract with SONATRACH that was immediately followed by more public anger. Far north, along the 1000 miles long shores, Italy with its oil company ENI is rumoured to most probably sign a historic agreement in Algiers that will allow it to officially win the operation of two offshore oil blocks East and West of the capital city. It looks as if the absent and dormant elites, political or business alike got together, and that people’s rebellion is the only way to fight climate breakdown.
Whether it is a legitimate offshore operation with diversification as its goal or merely a costly stunt to divert attention from the potential fracking of those ginormous pockets of shale oil in the deep Saharan south would remain to be seen.
Meanwhile in the UK, George Monbiot’s thoughts dated October 18, 2018, on the same issue of the country’s future being tossed alternatively between the capital’s plush offices and the countryside’s and villages bucolic streets.
As the fracking protesters show, a people’s rebellion is the only way to fight climate breakdown
Our politicians, under the influence of big business, have failed us. As they take the planet to the brink, it’s time for disruptive, nonviolent disobedience
It is hard to believe today, but the prevailing ethos among the educated elite was once public service. As the historian Tony Judt documented in Ill Fares the Land, the foremost ambition among graduates in the 1950s and 60s was, through government or the liberal professions, to serve their country. Their approach might have been patrician and often blinkered, but their intentions were mostly public and civic, not private and pecuniary.
Today, the notion of public service seems as quaint as a local post office. We expect those who govern us to grab what they can, permitting predatory banks and corporations to fleece the public realm, then collect their reward in the form of lucrative directorships. As the Edelman Corporation’s Trust Barometer survey reveals, trust worldwide has collapsed in all major institutions, and government is less trusted than any other.
As for the economic elite, as the consequences of their own greed and self-interest emerge, they seek, like the Roman oligarchs fleeing the collapse of the western empire, only to secure their survival against the indignant mob. An essay by the visionary author Douglas Rushkoff this summer, documenting his discussion with some of the world’s richest people, reveals that their most pressing concern is to find a refuge from climate breakdown, and economic and societal collapse. Should they move to New Zealand or Alaska? How will they pay their security guards once money is worthless? Could they upload their minds on to supercomputers? Survival Condo, the company turning former missile silos in Kansas into fortified bunkers, has so far sold every completed unit.
Most governments, like the UK, Germany, the US and Australia, push us towards the brink on behalf of their friendsTrust, the Edelman Corporation observes, “is now the deciding factor in whether a society can function”. Unfortunately, our mistrust is fully justified. Those who have destroyed belief in governments exploit its collapse, railing against a liberal elite (by which they mean people still engaged in public service) while working for the real and illiberal elite. As the political economist William Davies points out, “sovereignty” is used as a code for rejecting the very notion of governing as “a complex, modern, fact-based set of activities that requires technical expertise and permanent officials”.
Nowhere is the gulf between public and private interests more obvious than in governments’ response to the climate crisis. On Monday, UK energy minister Claire Perry announced that she had asked her advisers to produce a roadmap to a zero-carbon economy. On the same day, fracking commenced at Preston New Road in Lancashire, enabled by the permission Perry sneaked through parliament on the last day before the summer recess.
The minister has justified fracking on the grounds that it helps the country affect a “transition to a lower-carbon economy”. But fracked gas has net emissions similar to, or worse than, those released by burning coal. As we are already emerging from the coal era in the UK without any help from fracking, this is in reality a transition away from renewables and back into fossil fuels.
