How Barcelona “superblocks” return city streets to the people

Published

on

As in Singapore and everywhere else in big urban cities around the world, air pollution and traffic congestions is a major problem for city planners and residents alike.

In a report by Inhabitat.com, we are shown how Barcelona City’s Urban Mobility Plan is carrying out a plan that promises a pathway to greener, cleaner, and more pedestrian-friendly urban living to overcome or at least reduce the problem.

The plan uses the concept of the “superblock”; that is creating a mini-neighborhood on a grid that restricts higher-speed traffic on the perimeter so that the interior roads are freed up for pedestrian-friendly public space.

This simple yet smart retrofit plans to reduce traffic by 21 percent over the next two years and is already implemented on Barcelona’s existing gridded neighborhoods.

For this purpose, alternative transportation will be better implemented (new orthogonal bus and bicycle networks, carpool and pedestrian lanes, etc.), and restrictive measures will be placed on private vehicles, such as an increase in the price of metered parking.

Other secondary objectives of the plan will be the compliance with European regulatory parameters of environmental quality, a reduction in noise and number of accidents, and an increase in pedestrian road space.

One of the first areas to implement the plan is a neighborhood of 400 M by 400 M nine square blocks

In the current nine square blocks, motorized traffic passes through all roads at 50 kilometers per hour but under the superblock plan, the inner four intersecting roads will be reclaimed for public space. Private vehicles may use those roads but will be restricted to speeds of 10 kilometers per hour.

According to the plan, the scheme could free up 160 intersections.

Janet Sanz, City Councillor for Ecology, Urbanism and Mobility said to the Guardian, “This plan sums up the essence of urban ecology, our objective is for Barcelona to be a city to live; as a Mediterranean city, its residents spend a long time on the streets.”

“Those streets need to be second homes or extensions of one’s residence; public spaces need to be the spaces to play, where green is not an anecdote – where the neighborhood’s history and local life have a presence.”

Braess’s paradox

An article in Scientific Americans wrote that researchers analyzing a commute from Harvard Square to Boston Common found that the solution to address traffic jams hinges on a theory, the Braess’s paradox. Which suggest that the improvement of a malfunctioning network can be accomplished by removing certain parts of it

Michael Gastner, a computer scientist at the Santa Fe Institute, said. “Because selfish drivers optimize a wrong function, they can be led to a better solution if you remove some of the network links.”

How so? In part, because closing roads make it more difficult for individual drivers to pick the best – and most selfish – route.

In the Boston example, the team found that the delay caused by selfish driving can be reduced by closing six roads.

Another kind of lawlessness could speed travel as well – a traffic design strategy known as shared streets. The practice removes traffic lights, street markings, and boundaries between the street and sidewalk.

The idea is that the lack of traffic regulation forces drivers to take more responsibility for their actions.

“The more uncomfortable the driver feels, the more he is forced to make eye contact on the street with pedestrians, other drivers and to intuitively go slower,” explains Chris Conway, a city engineer with Montgomery, Scientific American wrote. Other publications also touched on the matter, such as “Plus Math Magazine” that wrote an article, “Want less traffics? Built fewer roads!”

Other benefits in reducing the number of roads are the lowering of ambient temperature due to the retention of the sun’s heat by the roads and compelling drivers to switch to public transportation.

Singapore’s solution to reduce traffic jams, arguably, should not be increasing the number of roads at the expense of precious green space (such as Bukit Brown cemetery), but to reduce and streamline the existing network and to improve and expand the current public transportation system.

EU urged to designate Sarawak as ‘high risk‘ under anti-deforestation law

A coalition of environmental and Indigenous groups has called on the EU to designate Sarawak as high risk under its anti-deforestation law. Sarawak’s extensive deforestation and Indigenous rights violations pose serious risks, prompting calls for stricter EU import checks on timber and palm oil products from the region.

A coalition of environmental, human rights, and Indigenous organizations is urging the European Union (EU) to classify Malaysia’s Sarawak state as “high risk” under its new anti-deforestation regulation. Sarawak, home to millions of hectares of ancient rainforests, faces severe deforestation risks and violations of Indigenous peoples’ rights, according to a joint assessment by groups including Human Rights Watch, RimbaWatch, and SAVE Rivers.

The call to action comes ahead of the EU’s pending decision to categorize regions based on their deforestation risks under the new law.

The EU Deforestation-Free Products Regulation (EUDR), set to be enforced from January 2025, aims to curb the import of commodities like timber and palm oil linked to deforestation and human rights violations.

Sarawak’s history of deforestation, especially for timber and oil palm plantations, makes it a significant concern. A high-risk designation under the EUDR would lead to stricter import checks and increased due diligence requirements for EU companies dealing with products from Sarawak.

Land Rights Violations and Deforestation Concerns

The coalition’s analysis highlights Sarawak’s controversial land laws, which undermine Indigenous land rights while promoting commercial exploitation of the state’s forests.

According to Luciana Téllez Chávez, senior environment and human rights researcher at Human Rights Watch, Sarawak’s land code places “insurmountable obstacles” on Indigenous communities’ ability to gain legal recognition for their ancestral lands.

These laws allow companies to operate with impunity, often disregarding Indigenous land claims. The coalition argues that Sarawak’s record justifies a “high risk” classification, which would necessitate increased oversight of timber and palm oil imports into the EU.

Sarawak’s ambitious plans to expand industrial timber plantations, aiming to establish one million hectares by 2025, are another point of concern.

Achieving this goal would require converting over 400,000 hectares of naturally regenerating forests between 2022 and 2025. This trend poses a significant threat to biodiversity and the rights of Indigenous peoples.

Deficiencies in Certification and Transparency

Despite Sarawak’s reliance on the Malaysian Timber Certification Scheme (MTCS), civil society organizations have flagged significant flaws in the program.

Local activists argue that MTCS does not adequately protect Indigenous rights or prevent deforestation. Celine Lim, managing director of SAVE Rivers, emphasizes that logging continues on Indigenous lands without proper consultation or consent, further eroding trust in certification standards.

Additionally, Sarawak’s opaque land management practices hinder transparency. The state has not made available comprehensive data on Indigenous lands or disclosed the locations of leases granted to logging and palm oil companies.

This lack of transparency prevents Indigenous communities and civil society from holding companies and the government accountable.

EU’s Role in Enforcing Sustainable Practices

Under the EUDR, the European Commission will classify regions as “low, standard, or high risk” by the end of 2024.

A high-risk designation for Sarawak would mandate EU member states to triple their customs checks on imports of wood and palm oil products from the region.

EU-based companies would also need to conduct more rigorous checks to mitigate environmental and human rights violations linked to these products. This process would require close collaboration between the EU and Malaysian authorities to reduce risks and ensure compliance with the new regulation.

Sarawak’s timber and palm oil exports to the EU have been significant in recent years. According to a Sarawak government report, the state exported at least MYR 37.3 million (€7.8 million) worth of timber to EU countries like the Netherlands, France, and Greece in 2023.

The EU remains the third-largest market for Malaysian palm oil exports, underscoring the importance of Sarawak’s compliance with international sustainability standards.

Challenges in Malaysian Government Response

The Malaysian government has pushed back against the EUDR, criticizing its definitions and monitoring processes.

The government contends that industrial timber plantations, which involve replacing natural forests with single-species plantations, should not be classified as deforestation. Critics argue that this stance overlooks the environmental degradation and loss of biodiversity associated with such practices.

Adam Farhan, director of RimbaWatch, warns that Malaysia may be attempting to bypass EU restrictions by downplaying the scale of deforestation in timber plantations. Farhan stresses the need for stringent due diligence on Malaysian forest-risk commodities.

The federal government has mandated that palm oil plantations established after 31 December 2019, on deforested land, cannot receive sustainable certification under the Malaysian Sustainable Palm Oil (MSPO) standard.

However, enforcement remains uncertain, as states hold jurisdiction over land and forest administration. Civil society groups are urging the Malaysian government to strengthen its oversight mechanisms and improve its sustainability certification programs to meet EU requirements.

International and Local Advocacy for Reform

In May 2024, the coalition of civil society organizations submitted recommendations to Malaysia’s federal Plantation and Commodities Ministry, urging reforms to align with international human rights and environmental standards.

Key recommendations include incorporating the United Nations Declaration on the Rights of Indigenous Peoples into federal legislation and introducing laws to prevent strategic lawsuits against public participation (SLAPPs), which are often used to silence critics of deforestation practices. The government has not yet responded to these calls.

As the EU moves forward with its anti-deforestation law, the decision to designate Sarawak as high risk could have far-reaching implications for Malaysia’s timber and palm oil industries. Environmental groups argue that strong enforcement of the EUDR is necessary to prevent further forest loss and protect Indigenous communities’ rights in Sarawak.

Japanese scientists find microplastics are present in clouds

In Japan, researchers confirm microplastics in clouds, impacting climate. Airborne microplastics, 7.1 to 94.6 micrometers in size, found in cloud water, potentially affecting rapid cloud formation and climate systems.

WASHINGTON, UNITED STATES — Researchers in Japan have confirmed microplastics are present in clouds, where they are likely affecting the climate in ways that aren’t yet fully understood.

In a study published in Environmental Chemistry Letters, scientists climbed Mount Fuji and Mount Oyama in order to collect water from the mists that shroud their peaks, then applied advanced imaging techniques to the samples to determine their physical and chemical properties.

The team identified nine different types of polymers and one type of rubber in the airborne microplastics — ranging in size from 7.1 to 94.6 micrometers.

Each liter of cloud water contained between 6.7 to 13.9 pieces of the plastics.

What’s more, “hydrophilic” or water-loving polymers were abundant, suggesting the particles play a significant role in rapid cloud formation and thus climate systems.

“If the issue of ‘plastic air pollution’ is not addressed proactively, climate change and ecological risks may become a reality, causing irreversible and serious environmental damage in the future,” lead author Hiroshi Okochi of Waseda University warned in a statement Wednesday.

When microplastics reach the upper atmosphere and are exposed to ultraviolet radiation from sunlight, they degrade, contributing to greenhouse gasses, added Okochi.

Microplastics — defined as plastic particles under 5 millimeters — come from industrial effluent, textiles, synthetic car tires, personal care products and much more.

These tiny fragments have been discovered inside fish in the deepest recesses of the ocean peppering Arctic sea ice and blanketing the snows on the Pyrenees mountains between France and Spain.

But the mechanisms of their transport have remained unclear, with research on airborne microplastic transport in particular limited.

“To the best of our knowledge, this is the first report on airborne microplastics in cloud water,” the authors wrote in their paper.

Emerging evidence has linked microplastics to a range of impacts on heart and lung health, as well as cancers, in addition to widespread environmental harm.
