COSPAR and the Erasmus+ Education Programme

COSPAR’s participation in Erasmus+ programmes is part of the COSPAR Panel on Education’s new approach to its mission of developing “means and media to encourage and spread space-related education”. The StudenTs As plaNetary Defenders (StAnD) project aims to engage primary and secondary school students in the subject of asteroids, meteors, and planetary defence.

The 36-month StudenTs As plaNetary Defenders (StAnD) programme brings asteroids, comets, meteors and meteorites to the classroom using carefully prepared activities and experiments. The programme includes the installation of meteor detection cameras in participating schools and a specially designed kit for micrometeorite hunting. The partners involved have joined their expertise to design an integrated approach that will enable students to follow the journey of these cosmic visitors from the depths of space to our planet. StAnD will introduce a new trend of activities engaging students in their STEM (science, technology, engineering, and mathematics) curriculum and enhancing their interest in these fields.

The activities involved in the project also have the considerable potential of leading to new original scientific discoveries, such as the discovery of new asteroids and meteorite falls. Their teachers will receive training and support via massive open online courses and summer schools to prepare topics related to astronomy, the solar system, and space exploration. The teachers will make use of selected online resources to better present the contents to the students and will acquire innovative student-centred methodologies that facilitate the integration of digital content into the STEM curriculum. They will also receive training on how to use robotic telescopes and the relevant software to plan the observations, as well as how to operate and interpret the meteor images acquired by the camera systems. They will learn how to collect and identify the micrometeorite samples. The results of various phases of the project will be continuously disseminated, spreading the results among the participants, countries, at European and international level.

StAnD will be coordinated by the Istituto Nazionale di Astrofisica (INAF), Italy, with the active participation of COSPAR, France, NUCLIO, Portugal, Ellinogermaniki Agogi, Greece, and FTP-Europlanet, Germany.

At the heart of the COSPAR Panel on Education’s new initiatives is a move to enhance the professional development of educators. Efforts to bring space research to educators and trainers will be stepped up, by expanding the existing teacher-training programme during the biennial COSPAR Scientific Assemblies, by including this opportunity in the COSPAR Symposia, held in alternate years to the Assembly, and by forming partnerships with organisations such as the International Astronomical Union (IAU) and the Global HandsOn Universe (G-HOU). StAnD is the second Erasmus+ project COSPAR is involved with, following close on the heels of the EXpeditionary Program for Learning OppoRtunities in Analog Space Exploration (EXPLORE) programme.

The COSPAR President, Professor Pascale Ehrenfreund said: “Learning about space can capture the imagination of students, leading to increased interest in Science, Technology, Engineering, and Mathematics (STEM) subjects. This can foster a future workforce skilled in these critical areas. COSPAR is therefore engaging with teachers and educators worldwide to increase and sustain interest in STEM subjects and to encourage more young people to take up STEM careers to enter the space sector. I strongly believe we can make a difference and I look forward to following the progress of these Erasmus+ projects and to welcoming these students into the COSPAR community.

The Executive Director of COSPAR, Dr Jean-Claude Worms, stated: “COSPAR places great emphasis on educating new generations of school and university students in the space science areas, by supporting teachers through specific training programmes during COSPAR events, and by providing appropriate means to its Panel on Education. Our recent involvement with several dedicated partners in ERASMUS+ programmes is another step in that direction.”

Chair of COSPAR’s Panel on Education, Dr Rosa Doran, said: “I am a believer in the empowerment of educators to bring the new generation closer to their future careers. Bringing authentic research experience to students. These young people will develop with a different mindset towards innovation, with a better understanding of the scientific method and with a good starting point on the construction of their science capital. The Panel of Education of COSPAR has the ambition to be the facilitator of such possibilities and to bring the worlds of research and education closer."

Background

The COSPAR activity that is particularly relevant to this ERASMUS+ project is developed by the Panel on Education. The COSPAR Panel on Education, under the dynamic Chair Rosa Doran, aims to adopt a more active approach towards its growth and impact within COSPAR, to broaden its target audience from educators to a whole-school approach, involving all members of the schools and their local communities, to reach out to policy makers and to guarantee a deeper involvement of its members towards a common goal: generating greater awareness of the importance of space science and how it is already impacting society.

The Panel on Education works on the development of means and appropriate media for encouraging and spreading space-related education. It works with COSPAR Scientific Commission Chairs, Panels, and other interested parties to identify the audience to whom the outreach and education is aimed, whether primary and secondary schools, universities, the general public via journalistic media, students, and especially underprivileged students in countries where space-related activities do not exist.

The Panel seeks to identify how to make educational tools and media available, and it explores possible links to and interactions with already established educational programs on topics related to research areas covered by COSPAR. The Panel also establishes links and strategic partnerships and alliances, for example with UNESCO, so that its activities can be supported without unnecessary duplication. The four Officers in charge of this Panel, and the very large body of volunteers (both teachers and scientists) working to support its activities and events have extensive experience of developing international educational projects, including EU-funded programmes, in particular ERASMUS+.


StAnD Key Facts

What? Students As planetary Defenders (StAnD) aims to engage primary and secondary school students and teachers in the subject of asteroids, meteors, and planetary defence, raising interest in science and space exploration, and improving their skills in science, technology, engineering and mathematics (STEM) subjects. Students will have the opportunity to discover new asteroids in telescopic images obtained in Hawaii, USA, and study in more detail the properties of known asteroids and comets using robotic telescopes in observatories around the world. They will learn how to use new technologies, will improve their digital skills, and will work as teams in the different campaigns during the project.

Why? Several growing needs in education are targeted in StAnD. The project is designed to raise interest and awareness of the importance of STEM fields among young students; to upgrade educators’ skills and learning in various fields; to improve educators’ and learners’ digital literacy; and to bridge the digital divide, ensuring an inclusive environment. These are crucial areas for the future needs of society. Trained teachers will become better prepared for addressing STEM topics, leading to improved learning by the students. The activities will engage students and teachers and lead to potential scientific discoveries.

Who? The Istituto Nazionale di Astrofisica (INAF) is coordinating the project, leading the partnership of COSPAR, NUCLIO, Ellinogermaniki Agogi and FTP-Europlanet.

For whom? A minimum of 50 schools will be involved, reaching 135 educators and 1,500 students. The main target groups are schools, scientists, and other relevant stakeholders in the field of education.

How? Meteor detection cameras will be installed in each of the participating schools and students will operate them, with support from project members. These cameras will detect meteors that enter the Earth’s atmosphere and may register a meteor large enough to leave a remnant in the ground—a meteorite—that can be recovered by specialists, and possibly the re-entry of man-made objects. Students will also have the opportunity to recover micrometeorites, microscopic fragments of asteroids and comets, by using the Stardust Hunter kit that will be developed by the project team. The project will include: -

  • Teacher training sessions through massive open online courses (MOOC) and two summer schools;
  • Installation and operation of meteor detection cameras in participating schools;
  • Micrometeorite collection using the detection kits;
  • Asteroid Search Campaigns using professional telescopes in Hawaii on the framework of the International Astronomical Search Collaboration; and
  • Asteroid follow-up observations using the Las Cumbres Global Observatory telescopes.

Where? Initially in schools in Germany, Greece, Italy and Portugal, and it is hoped to mainstream the methodology being piloted in this project to other schools at a global level.

Duration? 36 months; starting 1 September 2023

Note to Editors

COSPAR, the Committee on Space Research, was created in 1958, at the dawn of the space age, under the aegis of the International Council of Scientific Unions, now the International Science Council (ISC). COSPAR’s objectives are to promote on an international level scientific research in space, with emphasis on the exchange of results, information and opinions, and to provide a forum, open to all scientists, for the discussion of problems affecting space research. In its first years of existence as an entity that ignores political considerations and views all questions solely from the scientific standpoint, COSPAR played an important role as an open bridge between East and West for cooperation in space. When this role became less prominent with the end of the Cold War, COSPAR focused its objectives on the progress of all kinds of research carried out with the use of space means. COSPAR has played a central role in the development of new space disciplines such as life sciences and fundamental physics in space, by facilitating the interaction between scientists in emerging space fields and senior space researchers. Another recent inclusion in our portfolio concerns social sciences and humanities, which aims to provide opportunities for COSPAR to engage with SSH communities, including in the education area, and gives a role to our organization that is commensurate with today’s interaction of space matters with the broader society.

A recent emphasis is the development of tighter bonds between science and industry, through the establishment of the Committee on Industry Relations, grouping 18 major aerospace companies worldwide, and advising COSPAR on how best to integrate the capabilities of industry into COSPAR’s activities and by doing so, to best serve the interests of industry and science in a synergistic way.

COSPAR strives to promote the use of space science for the benefit of humanity and for its adoption by developing countries and new space-faring nations, in particular through a series of Capacity Building Workshops which teach very practical skills enabling researchers to participate in international space research programs. COSPAR advises, as required, the United Nations and other intergovernmental organizations on space research matters and on the assessment of scientific issues in which space can play a role, for example the Group on Earth Observations (GEO), in which COSPAR is a Participating Organization. COSPAR is also the key entity worldwide in terms of developing, maintaining and promulgating clearly delineated policies and requirements as to the standards that must be achieved to protect against the harmful effects of biological interchange in the conduct of solar system exploration and use.

Who supports Putin? Men, older generations and traditionalists, study shows


Peer-Reviewed Publication

UNIVERSITY OF COLORADO AT BOULDER




An international team of researchers has released an exhaustive look at support for Russia’s autocratic President Vladimir Putin across several neighboring countries. 

The study, published Nov. 30 in the journal Political Geography, was a massive effort. From 2019 to 2020, researchers led by John O’Loughlin at CU Boulder contracted with local polling companies to survey more than 8,400 people face-to-face in six nations: Armenia, Belarus, Georgia, Kazakhstan, Moldova and Ukraine. 

The team’s findings give a deep look at the type of people who support Putin, a former KGB spy who once held a photoshoot of himself riding a horse shirtless. Perhaps unsurprisingly, the results reveal that Putin is more popular among men than women, and less popular among younger and more educated people. 

“Our research has shown that Putin’s machismo and his authoritarian personality appeal to people who have more close-minded personalities, hold traditional values and don’t trust science,” said John O’Loughlin, professor in the Institute of Behavioral Science and Department of Geography.

In the former Soviet Union, Putin remains a complicated presence.

In Georgia, for example, the survey found that Putin was wildly unpopular, with more than 70% of respondents indicating that they had “no trust at all” in the leader. He boasted much more favorable ratings in Belarus and Kazakhstan, which have traditionally held close ties with Russia. 

O’Loughlin noted that he and his colleagues conducted the surveys before Russia launched its long and bloody invasion of Ukraine in February 2022. The researchers are planning to return to the same respondents in early 2024 to see how the war may have reshaped, or not, their attitudes toward Putin.

They separately conducted phone interviews with hundreds of people living in parts of Ukraine under Kyiv control in October 2022, and responses show that the war has backfired on Putin. In the country, support for joining NATO, a military alliance including the U.S. and dozens of European nations, soared from 44% to 77% since 2019.

“It was dramatic,” O’Loughlin said. “We asked the same people exactly the same questions, and the shift in attitudes was incredible.”

Whether the same shifts will happen in other former Soviet Union nations is less clear.  

“We have what's called a ‘natural experiment,’” O’Loughlin said. “We weren’t expecting the war in Ukraine, but we can see the effects of the full-scale invasion on peoples’ attitudes about Putin and Russia and toward the West and NATO.”

Putin’s stamp of approval

Asking people about Putin, however, can be a loaded topic, he added. 

People don’t always tell the truth on surveys. In some cases, they may be worried about the consequences. In others, survey respondents merely give researchers the answers they think they want to hear. 

To get around those limitations, O’Loughlin and his colleagues undertook what researchers call an “endorsement experiment.”

During the roughly 45-minute surveys, the team asked participants a seemingly innocuous question—whether they supported drilling for oil in the Arctic. For half of the respondents, however, the researchers tacked on an extra caveat: “President Putin of Russia strongly favors oil drilling.”

“The difference between the more neutral question and the question mentioning Putin’s endorsement gives you an idea of his real support,” O’Loughlin said.

It made a difference, too. In Georgia, Moldova and Ukraine, the fake Putin endorsement made people less likely to support drilling in the Arctic. The opposite was true in Armenia, Belarus and Kazakhstan.

Appeal of the ‘strong man’

The findings could provide researchers with clues about why some people find autocratic leaders in the mold of Putin so appealing. 

Researchers, for example, asked the survey respondents if they agreed with the statement: “Husbands should make the important decisions in a marriage.”

People who said yes were significantly more likely to support Putin than those who disagreed. The same was true for people who agreed with the statement: “I see myself as conventional and uncreative.”

“Our biggest surprise was that these results were consistent across the different countries in our study,” O’Loughlin said. “It’s the same people in every place who like or dislike Putin.”

O’Loughlin noted that, in Russia, Putin has tapped into nostalgia for the former Soviet Union—an era that many people in the region, and especially older generations, still view as a time of relative peace and stability.

“In the U.S., that’s easy to dismiss, but many people want security, peace and quiet,” O’Loughlin said. “They believe that if you don’t have a strong, authoritarian leader, the whole society is going to collapse.”


Coauthors of the new study include Andrew Linke, a former doctoral student at CU Boulder now at the University of Utah, Gerald Toal at Virginia Tech and Kristin Bakke at University College London. 

The research was funded by the U.S. National Science Foundation.

 

Recent advances in tree nut research — walnuts, pecans and more


Peer-Reviewed Publication

AMERICAN CHEMICAL SOCIETY



As the holiday season approaches, many home kitchens will produce the mouthwatering smells of fresh-baked goods and comfort food. From macadamia nut cookies and pecan pies to turkey stuffing, nuts feature heavily in seasonal pastries and dishes. Below are some recent papers published in ACS journals that report new insights into popular tree nuts. Reporters can request free access to these papers by emailing newsroom@acs.org.

“Bulk and Compound-Specific Stable Isotope Analysis for the Authentication of Walnuts (Juglans regia) Origins”
Journal of Agricultural and Food Chemistry
Nov. 2, 2023
Some consumers prefer to purchase produce grown in certain places, but country of origin labels can be accidentally incorrect or falsified. So, a team assessed whether two kinds of stable isotope analysis could differentiate walnuts grown in seven countries. A major result of the study was that the amounts of fatty acids and amino acids were significantly different between walnuts grown in the U.S. and China. The researchers say that one of the techniques, compound-specific stable isotope analysis, could be particularly useful to determine the crop’s geographical origins.

“Texture Properties, Crude Fat, Fatty Acid Profiles, Total Soluble Solids, and Total Polyphenols for 21 Pecan Varieties and the Effects of the Harvest Year”
ACS Food Science & Technology
Oct. 6, 2023
Texture and nutritional content of pecan nuts can differ depending on variety, growing conditions and the harvest year in a tree’s two-year fruit cycle. To learn more about the impact of these factors, a team analyzed kernel texture, crude fat, fatty acids, total soluble solids and total polyphenols in eight common varieties of the nut from two consecutive harvest years. Texture parameters indicated that pecans of the same variety could have different consistencies year-to-year. However, the team determined that the pecan variety had a larger impact on nutritional composition than harvest year.

“Dietary Fibers of Tree Nuts Differ in Composition and Distinctly Impact the Fecal Microbiota and Metabolic Outcomes In Vitro”
Journal of Agricultural and Food Chemistry
June 19, 2023
Most tree nuts are rich in dietary fibers, substances that don’t get digested in the stomach and are instead fermented by gut microbes. Researchers separately ground up almonds, cashews, hazelnuts, pistachios and walnuts, and they measured the percentage of dietary fibers in the samples. Next, they compared the effects of each nut sample on gut microbes in vitro. Of the nuts tested, pistachios had the highest total dietary fiber content, but cashew fibers produced the largest amount of butyrate, a compound that promotes digestive health. However, the team says their results suggest that all tree nut fibers could boost beneficial microbes in the colon.

A new species of stalked puffball, a gasteroid fungus, has been named after the ‘Shai-Hulud’ sandworms of Frank Herbert's iconic science fiction novel series ‘Dune.’

Discovered in Hungary, the new species, Tulostoma shaihuludii, is one of four new species in the genus Tulostoma that were discovered and published in the journal MycoKeys. The other species are Tulostoma dunenseTulostoma hungaricum, and Tulostoma sacchariolens​​.

Researchers chose the name due to the worm-like appearance of the species’ fruiting body, coupled with the sandy habitat of the Pannonian Steppe, where it was discovered.

The team consisted of Péter Finy (Eötvös Loránd University, Hungary), Mikael Jeppson (University of Gothenburg, Sweden), Dániel G. Knapp (Linnaeus University, Sweden), Viktor Papp (Hungarian University of Agriculture and Life Sciences, Hungary), László Albert (Hungarian Mycological Society, Hungary), István Ölvedi (Hungarian Mycological Society, Hungary), Károly Bóka (Eötvös Loránd University, Hungary), Dóra Varga (Eötvös Loránd University, Hungary), Gábor M. Kovács (Eötvös Loránd University, Hungary), and Bálint Dima (Eötvös Loránd University, Hungary).

These discoveries have been particularly significant due to Hungary's steppe vegetation on sandy soil being identified as a hotspot for the stalked puffballs in Europe. The research team conducted a comprehensive taxonomic revision of gasteroid fungi in Hungary, contributing to the understanding of this group's diversity.

The discovery of Tulostoma shaihuludii demonstrates the intricate connections between species and their habitats. It also highlights the importance of geographic isolation in the emergence of new species, as seen in the case of Tulostoma dunense, which is closely related to North American species but distinctly different, as revealed by genetic analysis​​.

Professor: Working with Big Bang and ecosystems should make youth tremble

Peer-Reviewed Publication

UNIVERSITY OF COPENHAGEN - FACULTY OF SCIENCE




Shakespeare, Kant, Rembrandt and the Punic Wars. The humanities play a dominant role in our traditional conception of what Bildung is and in its purpose of making young people well-rounded.

Bildung has been a central concept in Danish primary and secondary schools for more than two-hundred years. But it is only since 2000 that the role of science in Bildunghas come into focus. Nevertheless, science is seen as an appendage, something secondary that is justified by the fact that it is knowledge one needs in order to solve societal problems and engage in democratic debates. It is here that we underestimate the educational potential of natural science. In the words of Professor Lars Ulriksen of the University of Copenhagen’s Department of Science Education:

"The prevailing wisdom is that science education should equip a person to be able to do something 'outwardly'. This is reflected in primary and secondary school curricula. That scientific knowledge should be used to be able to thoroughly comprehend arguments about climate models and nuclear power, for example, or to gain respect for nature and the environment, which in turn can be used to promote sustainability. And this is important, for certain. But the personal potential is entirely overlooked." In a research article in the Danish Mathematics and Scientific Education journal MONA, Ulriksen argues for precisely this view. [View of: No.3 (2023) (tidsskrift.dk)].

"So, there is an aspect of educational understanding not covered by the way professionals and educators currently view scientific education: namely, the part which deals with the formation of the individual through self-reflection and looking inward – where one asks questions like: Who am I? What kind of world am I in? Who am I in this world?" says Ulriksen.

Can open teenagers' eyes up to science

As for pondering life’s more philosophical questions, the natural sciences definitely have something to offer. According to Ulriksen,

"There is plenty of material that can be used to make young people tremble. Astrophysics is an obvious area, with topics like the Big Bang and the infinity of the universe. In mathematics and physics, a person may experience that they can analyze themselves to objective truths, that not all things are negotiable. In biology, our position in the ecosystem can evoke thoughts about a whole that we humans are part of. For example, how might it change our perception of identity to consider that our cells are constantly being broken down and restored? Is one always the same after all? These kinds of existential questions can help shape an individual on a personal level," he says.

If this aspect of science is put into play, it has potential with regards to the personal, introspective part of Bildung, as well as with regards to young people gaining a more nuanced view of science education. Lars Ulriksen points out:

"We know that there are problems with maintaining interest in science classes and the natural sciences among youth once they reach adolescence. It is usually said that they then begin to take a greater interest in themselves as human beings and want to find out more about psychology in particular. If we opened their eyes to the fact that science can actually give rise to this kind of subjective consideration, we might be able to capture the attention of some of the students that we are not yet reaching," says Lars Ulriksen.

Call out to teachers

The ball is thus being placed into the court of middle and high school teachers. They are the ones who are the first to see the potential of this side of science, which, according to Lars Ulriksen, can make students self aware in an altogether different way than the humanities can.

"After all, there is no automatic formative outcome simply by reading every word of Hamlet or The Merchant of Venice. It's about processing – about opening oneself up to the material and working to allow it in. In the humanities, it is just implemented more and is a more integrated aspect of teachers’ understandings. So, it's about sharpening our awareness that this is a relevant aspect of science education as well," he says.

Lars Ulriksen hopes that professionals will begin approaching the profession with this in mind:

"I don't think that all scientific material is suitable for this. But I encourage educators and textbook authors – when selecting material, topics or examples – to ask themselves: Is there anywhere here where I can get my students to work with aspects of a particular subject that open up big identity-forming questions? And can I, as a teacher, ask questions that invite students to relate science to themselves as human beings?"

According to Ulriksen, this is where the type of teaching can make a difference:

"Inquiry-based teaching would probably be useful here. That the teaching is organized in such a way that students work less with ready-made closed questions and answers and more with the opportunity to investigate things, and even ask questions with a sense of wonder that propels them to pursue their own curiosities. There are certain experiences and thought processes that work best when open-ended," Professor Ulriksen concludes.

 

FACT BOX: BILDUNG STATED BY LEGISLATION

Student self-formation is an aspect of both primary and secondary school education. In Danish secondary school legislation, it is stated explicitly. Here the purpose of upper secondary education is described as follows:

§ 1, subsection 3 Educational programmes must have a formative perspective that emphasizes the students' development of personal authority. As such, students must learn to relate reflectively and responsibly to their surroundings: fellow human beings, nature and society, as well as to their development. Educational programmes must also develop the creative and innovative abilities, as well as the critical senses of students.

 

Money to burn: Wealthy, white neighborhoods losing their heat shields

White, wealthy neighborhoods in the LA area are about to start feeling the same heat that has plagued poorer, Hispanic neighborhoods for generations. A new study shows the protective effect of income has largely eroded over the past 40 years, as landscape plants can’t keep up with the pace of climate warming. 

Published in the journal Urban Climate, the research cuts across neighborhoods, income levels, and race in the Los Angeles area between 1985 and 2021. It reveals a troubling forecast for city dwellers: it’s becoming unbearably hot, and the landscaping that used to mitigate that heat won’t work as well in the future. 

For decades, urban ecologists have believed that affluence consistently translates into more abundant vegetation and cooler temperatures. This idea, the “luxury effect,” remains true. However, this study is the first to demonstrate the effect is rapidly weakening. 

As a whole, the city warmed an average of 8.4 degrees Fahrenheit during the past four decades. 

“The rate of warming was certainly less in affluent neighborhoods, but there were no neighborhoods that got cooler,” said Dion Kucera, Ph.D. student in botany at UC Riverside and first author of the study. 

Specifically, the study used satellite and census data to examine the abundance of vegetation, temperatures on the ground, and the amount of cooling plants are providing in every neighborhood throughout the city. The data show the luxury effect on cooling in predominately wealthy, white areas was only 58% as strong in 2020 as it was in 1990. 

“In other words, there’s been an increase in equity in the city. But it’s not because poorer areas are improving in greenness or cooling. It’s that richer regions are getting worse,” Kucera said. 

“If these trends continue, it is likely that by 2030 there will be no income advantage for white residents over minority residents when it comes to cooling from plants,” he said. 

The images show fewer trees in Hispanic-dominated neighborhoods, which is one reason they have always been hotter. As time goes on, the researchers suggest the plants that do exist in those neighborhoods are less healthy as heat increases alongside longer and more frequent spells of drought. 

Given the trends, researchers were surprised to find that trees have been getting better at cooling ground surface temperatures over time. Even as the climate warms, plants are becoming more efficient at transpiration, meaning more water is evaporating from the pores in their leaves. However, they are not getting better at transpiration as fast as the heat is increasing. 

In addition, the researchers warn there are temperature thresholds above which plants will no longer be able to transpire, or cool the ground, as they have been doing. 

“The warming the city has experienced is less than it would have been overall, thanks to plants. But as things get hotter, it is stressing plants’ ability to help. Transpiration will eventually max out, and though this was not part of what we found in the study, I expect the city will get much hotter much faster then,” Kucera said. 

The researchers also theorize that wealthy residents planting water-wise gardens, in response to drought, are also increasing the heat in their neighborhoods. While cacti and succulents use water more sparingly, they do not offer as much cooling as leafy trees and shrubs. 

“There is a clear message from the results. Income inequality will grow smaller. And it will get a whole lot hotter a whole lot faster in the future for rich people,” said Darrel Jenerette, UCR botany professor and co-author of the study.

However, the researchers stress that plants still have a role to play in offsetting the worst of the increasing heat, as do other cooling measures. 

“Poorer, minority-dominated neighborhoods are already in a lot of trouble when it comes to health impacts from extreme heat. Our study shows they have always borne the brunt of warming and still do,” Jenerette said. 

“Finding ways to ensure things like air conditioning and insulation are available to everyone is absolutely key to reducing the harm that is certain to come from climate change.”

Furthermore, the researchers believe the lessons from Los Angeles are likely to apply to cities around the world. 

“We definitely think of the LA area as a model for the effects of climate on vegetation globally. It’s one of the largest, most diverse cities in the world, especially for trees. The climate effects in LA are likely to mirror what is happening in cities throughout the world that are also getting hotter,” Jenerette said. 

Abundant vegetation still protects wealthy LA neighborhoods from heat, but less so now than in the past.

In a pioneering study published in Geo-spatial Information Science, a research group led by Yuyu Zhou from The University of Hong Kong developed an integrated framework that achieves 94% accuracy in mapping building functions across 50 U.S. cities using multi-source web-based geospatial data, offering potential for worldwide application. The team utilized TripAdvisor.com and Google Maps as primary data sources due to their extensive coverage and dynamic updating features. 

Highlights

1. Broad Applicability: With the universal presence of Google Maps and TripAdvisor.com, this framework can potentially be applied to cities globally, offering a standardized method for urban building function mapping.

2. Resource Efficiency: The study circumvents the expensive and tedious process of gathering social sensing datasets. Instead, it capitalizes on readily available online geospatial data, ensuring scalability and cost-effectiveness.

3. Potential Extensions: The framework can further be utilized for a myriad of urban studies, from evaluating green spaces to assessing pedestrian exposure to environmental pollutants.

The research findings are promising. The proposed framework demonstrated an impressive average overall accuracy of 94% with a kappa coefficient of 0.63. While the study centered on U.S. cities, its potential for global application, especially in regions with data accessibility challenges, is immense. Furthermore, as the digital footprint of cities grows, the researchers see opportunities to refine this approach. They recommend future endeavors to enhance mapping accuracy, especially in multi-functional buildings and in regions less covered by TripAdvisor.com and Google Maps. This research provides a powerful tool for city planners, policy makers, and researchers, with the hope that the integrated framework becomes an essential asset in the global pursuit of sustainable, efficient, and inclusive urban spaces.
