Posted on January 15, 2021 by Manila Standard is about how Smart cities, e-governance help urban resilience and how this latter is visualised as from the Philippines.
Smart Cities are fast becoming one of the world’s most critical industries as more countries invest in technologies to improve the delivery of government service.
In its simplest essence, a smart city is all about providing people a better quality of life by using different types of electronic methods and sensors to collect data. The insights gained from that data are utilized to manage assets, resources, and even services efficiently, helping governments to improve their operations across the city. It also enables e-governance or the integration of Information and Communication Technology (ICT) in all the processes to enhance the government’s ability to address the needs of the public.
By 2025, smart city development worldwide is estimated to create business opportunities worth $2.46 trillion, as revealed by a report released by tech research firm Frost and Sullivan. This trend is driven by the uncertainties of the post-pandemic work, which will compel cities to focus more on developing collaborative, data-driven infrastructure to provide healthcare and public security, as well as resilience to natural disasters.
Laying the Groundwork
In the Philippines, the national government has been pushing the adoption of smart city technologies. For instance, the Department of Information and Communications Technology (DICT), being the country’s primary agency promoting the adoption of eGovernment Services (ICT-ES), has developed the E-Government Masterplan (EGMP) 2022.
This plan outlines DICT’s intent of developing the country’s e-government systems through the digital transformation of services, such as public health, education, and other programs that cut across the whole of government. By doing so, DICT aims to create a networked and collaborative environment for improved public service delivery.
Additionally, as the ongoing pandemic accelerates innovation, some local governments have laid their plans for their smart city initiatives, especially on e-governance. Baguio City, for instance, has recently announced its investments to transform into e-government using Information and Communication Technologies (ICTs) and other web-based telecommunication technologies, such as crowd density monitoring and real-time weather prediction, to improve the delivery of public service.
Aside from Baguio, the New Clark City in Pampanga, Davao, Cebu, and Manila have also previously laid the groundwork to make their areas smarter through the adoption of e-governance technologies.
The need for the adoption
For Vertiv, a global provider of critical digital infrastructure and continuity solutions, the digital transformation and e-governance initiatives of all the cities in the country, just like the other smart cities across the globe, provide an opportunity to make the entire Philippines more resilient challenges like the current public health crisis or natural calamities.
Last year, the country was identified as one of the most vulnerable to climate change by the Global Peace Index of the Institute of Economics and Peace (IEP) due to its high exposure to natural hazards, such as typhoons, landslides, floods, and droughts, as well as its heavy reliance to its climate-sensitive natural resources.
The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAG-ASA) also noted that more tropical cyclones are entering the Philippine Area of Responsibility (PAR) than anywhere else in the world. Recently, the Philippines experienced five typhoons in a row—Quinta, Rolly, Siony, Tonyo, and Ulysses—which all made landfall in the country within at least a month. All these typhoons left trails of devastation, which include physical injuries, casualties, and damages to agriculture and other properties.
“Following this devastation, preparedness for typhoons and other calamities has never been more important, for instance, in getting necessary data where they can draw insights to efficiently conduct pre-evacuation of residents in flood-prone and vulnerable areas. And as IT becomes integral, government agencies must have a ready infrastructure in place to ensure that services go on unhampered and citizens have access to services they need,” said Jason Lim, country manager of Vertiv Philippines.
To help local governments in tackling these IT infrastructure challenges, Vertiv brings together cutting-edge E-Governance Solutions to ensure uninterrupted operations, optimal performance, and scalability of data centers, communication networks, and other critical IT facilities needed in creating smarter and more resilient cities.

Hager Harabech elaborates in Phys.Org how Amid Nile dam tensions, Egypt recalls Aswan 50 years on.
13 January 2021
Half a century since Egypt’s ground-breaking Aswan dam was inaugurated with much fanfare, harnessing the Nile for hydropower and irrigation, the giant barrier is still criticised for its human and environmental toll.
It is also a stark reminder—amid high tensions today as Addis Ababa fills its colossal Grand Ethiopian Renaissance Dam (GERD) upstream—of just how volatile politics over the life-giving, but finite, Nile water resources can be.
The Aswan High Dam was spearheaded in the early 1950s by charismatic pan-Arabist president Gamal Abdel Nasser.
Egypt, where the river provides some 97 percent of water for more than 100 million people, is the final section of the Nile’s 6,650-kilometre (4,130-mile), 10-nation journey to the Mediterranean.
For millennia, the North African country was at the mercy of the seasonal rise and fall of the river, dependent on the rainfall in nations far upstream.
But the 111-metre-high and 3.6-kilometre-wide Aswan High Dam, dwarfing the far smaller Aswan Low Dam built under British rule in 1902, crucially gave Cairo power to regulate the flow.
It was a “very important hydro-political act”, said geographer and author Habib Ayeb, a Nile expert who has taught at universities in Cairo and Paris.
The dam was inaugurated on January 15, 1971, three months after Nasser’s death, by his successor Anwar al-Sadat.
For the first time, “an Egyptian president decided to manage the Nile within Egypt”, to develop agriculture and the economy in the country, Ayeb added.
For Egypt, an otherwise desert nation where 97 percent of the population lives along the green and fertile Nile banks, the dam revolutionised its relationship with the land.
“The dam offered a reprieve to Egyptians by giving them enough water… and protecting them from the hazards of floods, which could be absolutely catastrophic,” said Ayeb.
It also brought electricity to much of the country, a move Nasser said was key to developing the nation.
Abdel Hakim Hassanein, who overlooks the river from his home close to the dam, some 700 kilometres south of Cairo, praised its construction.
“We didn’t have electricity before, we used oil lamps,” the 68-year-old said, adding that work at the dem remains a key source of local jobs.
Ethiopia, the second most populous nation in Africa, today uses similar arguments, saying its 145-metre (475-foot) GERD Blue Nile barrier—set to be Africa’s largest hydro-electric dam—is vital to provide power for its 110 million people.
But Egypt, with the Arab world’s largest population, sees the GERD as an existential threat.
‘Belly of the desert’
In the 1960s, many Egyptians also saw the Aswan dam as a threat to their lives—in a different way.
The lake behind the dam flooded the homeland of Egypt’s Nubian people, forcing tens of thousands to leave.
“For the Nubians, the High Dam is a symbol of oppression,” said rights activist Fawzi Gayer. “It wiped out a civilisation.”
Gayer was born just after his family was relocated to a dusty town its Nubian residents call Abu Simbel “Displacement”.
“We’re talking about a community with a Nilotic identity that breathes the Nile… and we have been thrown into the belly of the desert,” said Gayer.
“The elderly died of shock.”
The Nubians’ long-running demand for a “right of return” was included in the 2014 constitution, but their lands have been swallowed by the 355-kilometre-long Lake Nasser, which stretches south into Sudan.
It was not only people who had to move; the waters threatened to drown the three-millenium-old Pharaonic temples at Abu Simbel, kickstarting a massive UNESCO-led rescue mission that took eight years.
The ancient complex, including giant stone carved statues, was dismantled and moved to a new location, in one of the world’s biggest archaeological rescue operations.
There were environmental consequences too.
The creation of the giant lake also upset the river’s delicate ecosystem, holding back the fertile silt deposits, causing erosion and increasing use of chemical fertilisers.
For Ayeb, the dam also “proved to be a political bomb”.
In building Aswan, Egypt and Sudan agreed a Nile water sharing deal, but did not include any other upstream nations, including Ethiopia.
“It created the foundations for the break-up of the Nile basin as a framework for a common good,” said Ayeb.
Today, Addis Ababa, Cairo and Khartoum are mired in long-running fractious talks over the filling and operation of the GERD dam.
But, according to Ayeb, the critical challenge for Egypt is the management of the water it gets at present.
“Even if Ethiopia stopped its dam, there wouldn’t be enough water,” he said, arguing Egypt should halt desert irrigation—where nearly half the water is lost by evaporation—and stop agricultural exports.
Ayeb believes Cairo needs a new water and agricultural policy entirely.
Saudi Arabia unveils THE LINE a linear development of smart cities connected without cars as reported by DesignBoom seems to be a significant step out of the fossil fuels grip on any mode of transport but only in this corner of the country.
Saudi Arabia has unveiled plans for THE LINE, a 170 kilometer (106 mile) belt of communities connected without the need for cars or roads. described as ‘a revolution in urban living’, the project has been put forward as a blueprint for how people can co-exist in harmony with the planet. THE LINE will be completely free of cars and streets, with residents given access to nature and all of their daily needs within a walking distance of five minutes. furthermore, the team behind the project says that the linear development of hyper-connected AI-enabled communities will be powered by 100% clean energy.

Located in NEOM, linking the coast of the red sea with the mountains and upper valleys of the north-west of Saudi Arabia, THE LINE was announced by his royal highness Mohammed bin Salman, crown prince and chairman of the NEOM company board of directors.‘By 2050, one billion people will have to relocate due to rising CO2 emissions and sea levels,’ says his royal highness. ‘90% of people breathe polluted air. why should we sacrifice nature for the sake of development? Why should seven million people die every year because of pollution? why should we lose one million people every year due to traffic accidents? and why should we accept wasting years of our lives commuting? therefore, we need to transform the concept of a conventional city into that of a futuristic one.’
Although walkability will define life on THE LINE, with all essential daily services within a short walk, ultra-high-speed transit and autonomous mobility solutions will make travel easier and give residents the opportunity to reclaim time to spend on health and well-being. It is expected that no journey will take longer than 20 minutes. the communities themselves will be powered by artificial intelligence and will continuously learn in order to ‘make life easier’ for both residents and businesses. It is estimated that 90% of available data will be harnessed to enhance infrastructure capabilities. from an environmental perspective, THE LINE will comprise carbon-positive urban developments powered by 100% clean energy.
NEOM is a region in northwest Saudi Arabia on the Red Sea being built from the ground up as a ‘living laboratory’. Eventually the location, comprising towns and cities, ports and enterprise zones, research centers, sports and entertainment venues, and tourist destinations, will be the home and workplace to more than a million residents from around the world. It is hoped that THE LINE will create 380,000 new jobs, spur economic diversification, and contribute SAR 180bn ($48bn USD) to domestic GDP by 2030. construction of THE LINE will get underway in early 2021.
Sam Bowman back in December 2020 wrote this article on Sustainability From A Construction Standpoint whereby he demonstrates that all construction-related matters do not have to have any bearing on the planet.
It seems as though the more we examine our day-to-day actions, the clearer the extent of our environmental damage becomes. Almost every aspect of the way we live our lives has the potential to have a destructive influence. This is why it is so important that we take time to understand how we can more effectively coexist with the ecosystem. Sustainability sits at the heart of this idea.
Many of us are making changes to the ways we work, eat, and travel to have more positive influences on our planet. One of the key ways we can make a long-term difference is in our approach to construction. Whether building a new home is a professional or personal project, there are adjustments we can make in design, materials, and internal systems. These can both minimize the initial use of resources, and make the building itself a more environmentally friendly home to live in. Studies have even found that green buildings can be instrumental in minimizing pollution’s effect on mortality rates and thus reduce pressure on public health services.
So, what do these sustainable construction elements look like? How does the way we design and build our homes have a tangible effect on our planet? The truth is, there are a lot of areas we can improve on. But we’re going to take a closer look at a few key areas of focus when it comes to sustainable construction.
Our homes are the primary culprits of excessive energy consumption. This is not only important from a general sustainability and cost-saving perspective. One recent study has reported that residential energy consumption is responsible for around 20% of greenhouse gas emissions in the U.S. Therefore those constructing new homes must take measures that both improve energy efficiency and utilize less harmful forms of energy production.
Some key approaches in this area include:
This is one of the primary areas construction professionals focus on when building energy-efficient homes. Taking the time, and a little investment to obtain insulation materials and apply them from the outset of construction can make a huge difference to home sustainability. This is because an airtight home prevents thermal bridging, which is heat escaping through the walls. However, using a large quantity of insulating material isn’t especially sustainable. It’s best to obtain insulation with high levels of thermal heat resistance — known as an R-rating — but lower quantities.
Solar Panels. Choosing to go solar at the construction stage is a more sustainable approach for a variety of reasons. The most obvious is the ultimate reduction in fossil fuel usage. However, it also reduces unnecessary utilization of construction materials, and the resources used to manufacture them — panels can be arranged to effectively replace these areas of the building. For those on a budget, installing solar panels as part of initial construction can reduce costs in other areas such as roofing materials, and solar water heating installation.
Heating and Cooling. One of the areas of most energy expenditure in American homes is heating and cooling. Aside from the aforementioned insulation, choosing the right heating, ventilation, and air conditioning (HVAC) approach can have a huge impact on how sustainable a home is. This involves understanding what system is most appropriate for the size and shape of the space being constructed. A geothermal heat pump system may well be the most efficient option in colder climates and larger constructions. However, in small to medium spaces, mini-split heating and cooling appliances are less of a drain on energy, and only need to be utilized for short periods to heat or cool individual rooms.
The real estate industry is finding that there’s a growing demand for homes with sustainable features. However, we should take the approach that sustainability should be a consideration from the outset. It’s not just an additional feature, but an integral part of the home itself. Material choices play an important role here.
From the perspective of the body of the building, concrete continues to be a popular choice. However, it is also one of the least sustainable materials — its production is responsible for around 8% of greenhouse gas emissions. Alternatives are becoming increasingly accessible. Ferrock, for example, is an iron-based compound that incorporates recycled waste materials, resulting in it being a carbon-negative construction option. Even in circumstances where a concrete outer shell is needed, its use can still be reduced. Tightly packed straw bales can allow for thinner concrete outer walls and even minimal use of plaster and gypsum on the inside of the home.
Material considerations are integral to making how we live with the building more sustainable, too. Thermal mass — a material’s ability to absorb and retain heat — is particularly important for walls and foundations. Understanding these properties help us to make intelligent choices about the most sustainable material for the location of the building. High thermal mass elements like brick and stone allow for those homes in cooler climates to absorb more heat from the sun and spread it throughout the home. While low thermal mass items such as steel and wood can be more appropriate for high-temperature areas where coolness needs to be maintained. This is conducive to long term sustainability, as it is more reliant upon the renewable properties of the natural environment rather than putting pressure on temperature controls that consume large amounts of energy and emit waste.
The design of the building itself can have an impact on its sustainability. Architects are increasingly expected to devise solutions that support environmentally friendly construction, enable sustainable occupation, and reduce the negative impact on the spaces these homes inhabit.
One such approach is vertical design. In the U.S., we have vast geography to enjoy, and as such we have developed a tradition of creating large, sprawling homes that extend outward. However, with populations on the rise, particularly in cities, this isn’t a sustainable approach. Increased demand for space means that architects are straying away from looking outward, and looking upward instead. Homes with more floors also have the benefit of being more energy efficient; they have fewer exposed walls, and heat rising from the bottom of the home helps to heat the whole house.
Architects are also considering how to cut down on unnecessary material expenditure and construction emissions. A popular solution to this is learning how we can adapt to what already exists. Cargotecture uses old shipping containers as the basis for construction. This provides a modular approach to architectural design, giving scope for tailoring, and even later additions. It also tends to have a shorter construction process, reducing waste during building. That said, the tiny home movement has also become a popular choice to minimize the use of construction materials. These houses, generally less than 500 square feet, also limit their impact on the environment. As detailed in the linked resource, they also tend to produce 14 times less carbon than the average home.
We have a responsibility to consider how all elements of our lives can be made more sustainable. As such, whenever we build a new home we must put time into making choices that minimize our negative impact on the planet in both the short and long term. The materials, energy systems, and architectural styles that are conducive to sustainability are becoming more accessible. We, therefore, have fewer excuses not to make our environmental and social responsibilities forefront in our construction decisions.
Researchers have advanced understanding of how wireless charging roads might influence driver behaviour.
By applying statistical geometry to analysing urban road networks, King Abdullah University of Science and Technology (KAUST) researchers have developed city planning in a future where electric vehicles (EVs) dominate the car market.
“Our work is motivated by the global trend of moving towards green transportation and EVs,” says postdoc Mustafa Kishk.
“Efficient dynamic charging systems, such as wireless power transfer systems installed under roads, are being developed by researchers and technology companies around the world as a way to charge EVs while driving without the need to stop. In this context, there is a need to mathematically analyse the large-scale deployment of charging roads in metropolitan cities.”
Many factors come into play when charging roads are added to the urban road network. Drivers may seek out charging roads on their commute, which has implications for urban planning and traffic control. Meanwhile, the density of charging road installations in a city, and the likely time spent on and between the charging roads by commuters, could influence the size of batteries installed in EVs by car manufacturers.
Calculating the metrics that could be used to analyze a charging road network is very significant, as Kishk’s lab colleague, Duc Minh Nguyen, explains.
“Our main challenge is that the metrics used to evaluate the performance of dynamic charging deployment, such as the distance to the nearest charging road on a random trip, depend on the starting and ending points of each trip,” says Nguyen.
“To correctly capture those metrics, we had to explicitly list all possible situations, compute the metrics in each case and evaluate how likely it is for each situation to happen in reality. For this, we used an approach called stochastic geometry to model and analyze how these metrics are affected by factors such as the density of roads and the frequency of dynamic charging deployment.”
Applying this analysis to the Manhattan area of New York, which has a road density of one road every 63 meters, Kishk and Nguyen with research leader Mohamed-Slim Alouini determined that a driver would have an 80 percent chance of encountering a charging road after driving for 500 meters when wireless charging is installed on 20 percent of roads.
“This is the first study to incorporate stochastic geometry into the performance analysis of charging road deployment in metropolitan cities,” Kishk says. “It is an important step towards a better understanding of charging road deployment in metropolitan cities.”
