SINGAPORE, June 13 (Reuters) – Global reservoir volumes fell during the last 20 years despite a construction boom that drove up storage capacity, a new study showed on Tuesday, suggesting that new dams will not be enough to solve growing strain on the world’s water supplies.
Satellite data showed that water sequestered in 7,245 reservoirs across the world fell from 1999 to 2018, despite a 28 cubic kilometre annual increase in capacity, a study published by Nature Communications said.
Climate change was a “critical factor” in reducing reservoir efficiency, said lead author Huilin Gao of Texas A&M University, but rising water demand also played a role.
“Even if temperatures stop rising, increasing demand and new construction are likely to continue,” he added.
The decline in storage volumes was concentrated in the south, especially Africa and South America, where water demand increased rapidly and new reservoirs didn’t fill up as quickly as expected.
The study did not account for the impact of sedimentation, a persistent problem that is predicted to cut storage capacity by a quarter by 2050, according to a January paper by the United Nations University.
Lengthy droughts have raised questions about the feasibility of large reservoirs. China saw hydropower output plummet last summer as a result of record-high temperatures across the Yangtze basin.
The International Hydropower Association said last week that new dams and reservoirs played a “crucial mitigating role in an era of increasing climate extremes”, making it easier to regulate water flows.
“As the climate gets more volatile, we will need more, not less, water infrastructure, with the bonus of much-needed low-carbon electricity,” it said.
China has also repeatedly said its enhanced ability to store and release water on the upper reaches of the Yangtze has alleviated downstream floods and droughts
Unlike many regions, China’s storage levels increased slightly over 1999-2018 as a result of higher run-off in major river basins, suggesting it will benefit from new reservoirs, Gao said.
“But this highly depends on future climate, especially since most regions have experienced decreasing run-off,” he said.

Referencing the Rubik’s cube, Edwin Diender, Chief Innovation Officer: Global Electric Power Digitalisation Business Unit, Huawei Technologies, Thailand, said each cube represents something or someone.
He was speaking on the second day of Enlit Africa 2023, focusing on the theme, Find the Right Technologies to Power the Global Energy Transition.
A cube that contains all the requisite components has the potential to link up the worldwide web of energy, he said.
“It is energy powering the construction of intelligent cities.
“The digital journey is passing phases. It’s a journey that follows programmes and initiatives and brought together as pieces through universal infrastructure.”
Diender said the conversion of analogue to digital is the first step to digitisation. In the energy sector, for example, analogue meters are replaced by smart meters, an item that is digitised and may be “the first step on this journey.”
The next step involves different building blocks that are brought together in a smart system that’s intelligent. This cube connects to many other cubes by a digital framework.
Diender said Huawei is looking at other forms of infrastructure, including electric power digitisation.
This would encompass finding the right technologies to help drive the digital journey for the energy industry.
Harnessing electricity transmission through digitisation
The company wants to “grab opportunities” like a software defined grid, intelligent power plant and green intelligent energy solutions. It wants to bridge industry requirements with digital technologies and finding the right technologies for industrial scenarios.
“The digital journey is a collaborative journey. We are working closely with customers worldwide in the electric power industry.”
He also cited technology solutions that can be used to protect power infrastructure – like an intelligent substation inspection system. Diender said the award-winning Yancheng Industrial Park was an example of Huawei looking at digital energy solutions.
The Yancheng Park project was jointly developed by the company and the Yancheng Power Supply Company, a subsidiary of the State Grid Corporation of China.
“The project uses the triple-dimensional model for energy transformation, decarbonisation, and digital transformation.
“By focusing on the three scenarios of smart energy management, carbon management, and campus management, this project delivers real-time monitoring of energy equipment, strong carbon emission management, intelligent and convenient access control management, and intelligent and coordinated micro-grid control.
“The campus is powered by complementary energy sources and integrates its energy consumption system with on-campus terminals.
“The project is a showcase of an intelligent and low-carbon campus that contributes to a green, low-carbon, safe, and efficient modern energy system.”
(TAP) – On 16/03/2023, TUNIS/Tunisia. The Union for the Mediterranean (UfM) launched a call for applications to finance projects aimed at promoting employment and entrepreneurship in the green economy sector. The aim is to support the environmental transition of the economies of 7 Mediterranean countries, including Tunisia.
According to information published Thursday by the UfM, this call for applications is intended for NGOs working to support vulnerable populations disproportionately affected by the consequences of climate change and by the evolution of the socio-economic context.
Eligible for this call for applications are non-profit NGOs active in the field of environmental transition of economies in an inclusive manner and with respect for social justice. These NGOs must be based in Algeria, Egypt, Jordan, Lebanon, Morocco, Mauritania, Palestine or Tunisia, with priority given to regional projects. The deadline for applications is May 29, 2023.
The selected candidates will benefit from financial support ranging from 150,000 to 300,000 euros (which represents a sum varying between 500,000 and 1 million dinars) per project, as well as from the UfM’s technical expertise, which will give them greater visibility.
Funded by the UfM with the support of the German Development Cooperation (GIZ), on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ) and the Spanish Agency for International Development Cooperation (AECID), this initiative, in its first edition, launched in 2020, helped 18,000 people, mainly young people and women, from seven UfM member states (Greece, Italy, Jordan, Lebanon, Malta, Morocco and Tunisia).
These projects address employment challenges in the areas of entrepreneurship, women’s empowerment, sustainable tourism, and education and research.
The green economy, as well as “green” jobs, are set to play a key role in the sustainable recovery of the Mediterranean region from the COVID-19 pandemic.
ZAWYATRANSPORT states that the GCC countries, as per Strategy& should spend an extra $220bln to build an additional 1,100 km metro rail in their respective urban centres.

GCC cities will need an additional 1,100 km of metro systems by 2030, estimated to cost nearly $220 billion, global consultancy firm Strategy& said in a new report.
The cities currently have 400 km and will need the expansion of metro tracks to meet the growing population demand.
As of 2022, Dubai and Doha have 90 km and 76 km of operational metro system tracks, respectively.
Riyadh is planning to launch a 176 km metro system by 2024. Saudi Arabia will need an extra capital investment of $34 billion by 2030 in addition to the $40 billion already spent.
Meanwhile, Abu Dhabi began electric bus trials in 2019 and has outlined plans for a 131 km metro system by 2030.
Although the cost is significant, a properly implemented and funded metro system can generate three to four times in direct and indirect socioeconomic benefits.
“If cities were to build the additional roughly 1,100 km of metro rail required by 2030, they could realise direct and indirect socio-economic benefits worth around $700 billion over a 20-year period,” said Mark Haddad, Partner with Strategy& Middle East.
Ensuring that current and future metro systems achieve such returns requires a framework based on four pillars that rest upon four foundational elements. These will help cities realise the anticipated returns and implement a metro system in a cost-efficient and effective manner.
The four pillars are clear objectives, integrated planning, high-quality service & customer-centric experience and commercial mindset.
These four pillars of the implementation framework rest on four elements: effective governance; policies and incentives to support transit adoption; funding throughout system development, launch and early operations and local capabilities that enable effective long-term management.
Ruggero Moretto, Principal with Strategy& Middle East, stated that properly implemented and managed metro systems could create long-term socioeconomic returns, promote sustainability, and improve the quality of life for residents.

Built to disappear: World Cup stadium 974
By Suman Naishadham
DOHA, Qatar (AP) — Of the seven stadiums Qatar built for the World Cup, one will disappear after the tournament.
That’s what the games’ organizers have said about Stadium 974 in Doha — a port-side structure with more than 40,000 seats partially built from recycled shipping containers and steel.
Qatar says the stadium will be fully dismantled after the World Cup and could be shipped to countries that need the infrastructure. Outside experts have praised the design, but say more needs to be known about what happens to the stadium after the event.
“Designing for disassembly is one of the main principles of sustainable building,” said Karim Elgendy, an associate fellow at the London-based Chatham House think tank who previously worked as a climate consultant for the World Cup.
“It allows for the natural restoration of a building site or its reuse for another function,” he said, adding that a number of factors need to considered “before we call a building sustainable.”
Buildings are responsible for nearly 40% of the world’s energy-related carbon emissions. Of that, about 10% comes from “embodied” carbon or the greenhouse gas emissions related to the construction, maintenance and demolition of buildings.
Qatar has faced international criticism for its treatment of low-paid migrant workers who built over $200 billion worth of stadiums, metro lines and other infrastructure for the World Cup. Qatar says the criticism ignores labor reforms enacted in recent years.
Stadium 974, named after Qatar’s international dialing code and the number of containers used to build the stadium, is the only venue that Qatar constructed for the World Cup that isn’t air-conditioned. During a match Friday in which Switzerland defeated Serbia, the air was noticeably more humid and hot than in other venues.
The stadium is hosting only evening matches, when temperatures are cooler.
Fenwick Iribarren Architects, which designed Stadium 974 and two other World Cup stadiums, says the idea was to avoid building a “white elephant,” a stadium that is left unused or underused after the tournament ends, as happened following previous World Cups in South Africa, Brazil and Russia.
Qatar says it has developed plans for the other six stadiums after the games are over. Many will have a number of seats removed.
The multi-colored shipping containers are used as building blocks for Stadium 974 and also to house facilities such as restrooms in the interior of the structure. Like giant Lego blocks, the bright red, yellow and blue corrugated steel boxes appear suspended between layers of steel. The design gives the stadium an industrial feel.
Qatar has not detailed where the dismounted stadium will go after the tournament or even when it will be taken down. Organizers have said the stadium could be repurposed to build a venue of the same size elsewhere or multiple smaller stadiums.
Where its components go matters because of the emissions implicated by shipping them thousands of kilometers away.
Carbon Market Watch, an environmental watchdog group that investigated Qatar’s World Cup sustainability plans, said whether Stadium 974 has a lower carbon footprint than a permanent one comes down to “how many times, and how far, the stadium is transported and reassembled.”
FIFA and Qatar acknowledge that in a report estimating the stadium’s emissions. If the stadium is reused only once, they estimate its emissions would be lower than a permanent one as long as it is shipped fewer than 7,000 kilometers (about 4,350 miles) away.
If it’s repurposed more than once, it could be shipped farther and still be less polluting than a permanent venue, they said, because of how energy-intensive building multiple new stadiums is.
Qatar’s Supreme Committee for Delivery and Legacy, the organizing committee for the World Cup, did not respond to a request for more information about plans after the tournament.
The report also didn’t factor in operational emissions — or those produced from running a building — once the stadium is repurposed because standards vary in different countries, FIFA and Qatar said.

“The energy required for dismantling and shipping the building components will obviously need to be estimated,” Elgendy said, “but it is unlikely to outweigh the carbon embodied in the building materials.”
For now, the stadium’s design isn’t lost on spectators. On any game night, fans entering and leaving the stadium take selfies against its modern, industrial facade. The temporary stadium is hosting seven games in total — with the final one on Monday between Brazil and South Korea.
Jhonarel Miñoza, a 42-year-old Qatari resident originally from the Philippines, said she and her sister wanted to see a game in each of the seven stadiums.
Miñoza, an administrative officer who has lived in Qatar for five years, said she had heard about Stadium 974′s unconventional design before the game she attended on Friday.
“I was really eager to know how they built it,” Miñoza said. “When I came inside here, I was just checking how they did that.”
Traditional construction methods were no match for the earthquake that rocked Morocco on Friday night, an engineering expert says, and the area will continue to see such devastation unless updated building techniques are adopted.
