    Promoting pedestrian ecomobility in Riyadh City for sustainable urban development

    The Ecomobility is a cross-sectoral, global partnership, an environmentally friendly and socially inclusive way of transportation, seeking the promotion integration of cycling, walking, and passenging (Being a passenger in another’s car or a carpool)1, and wheeling (wheelchairs, non-motorized scooters, walking aids, skates, push scooters, trailer, hand carts, shopping carts/ trolleys, carrying aids)2. In this section, the study introduces the main pillars that will build on them to reach the objectives. Passenging, energy efficiency, partnership for sustainable urban development, and streets’ design (with more focus as one of the core prerequisites of the methods) are discussed here. Although this research approaches the clean and green environment from the window of excluding the fossil-fuel motorized means of transportation, if there is still a necessity, passenging owns a pack of advantages over private cars. As a main passenging option, Carpooling has a lot of benefits to the environment, human health, and social lives, e.g., saving money, better for the environment, Convenience, etc., which are briefed below.PassengingBeing a passenger in another’s car or carpooling that increases efficiency. The concept becomes more apparent, listing the benefits of carpooling as follows3:

    1.

    Saving money: sharing the cost of gas and parking, cutting expenses by nearly 50%; the more occupants in carpooling, the more saving, and is socially economical. Also, there will be a reduction in constructing new roads, maintenance, and air pollution-related health costs.

    2.

    Better environment: fewer cars on roads mean reduced Greenhouse Gas (GHG) emissions and better air quality.

    3.

    Better health: helps reduce some health risks for a human being, such as cardiovascular and respiratory diseases, allergies, and neurological effects.

    4.

    Convenience: provides commuting Convenience, less stress, and added advantage of companionship while commuting.

    5.

    Better commuting options: works better for people living where transit service may be non-existent or limited.

    Energy efficiencyA study was performed in China to reduce GHG; the study claimed that China targeted the peak around 20304. However, it is expected that the peak may come earlier than expected, which is reflected in the CO2 emission (from coal consumption and fossil fuels) to have its peak also before 2030. Another study evaluated the economic impacts of GHG emission reduction on the Brazilian economy reached that different sectoral targets may balance environmental benefits with the possible financial losses incurred by taxation policy or emission permits5.The energy efficiency studies touched key triggers to reduce carbon emissions, In parallel. An analytical study in China (2013) indicated that if greater intensity emission reduction measures were taken, the carbon emissions would reduce by 31.01 million tons by 2015 and 48.81 million tons by 20206. The previous results indicated the average reduction flow per time.Partnership for sustainable urban developmentSaving the environment is cooperative work that requires sharing experiences with other partners worldwide. The cooperation between the Gulf region and China in the last half of the decade is an example of a global partnership. The Gulf region has achieved a success story, economically and socially. Following a smart investment arrangement of natural resources, the region has succeeded in attracting and retaining international experience, therefore overcoming the discrepancy between its vast economy and small population-base lacking the instantly needed technical skills. The region has collected considerable wealth during the process, financially and else7.The primary purpose of Ecomobility, mentioned previously, is enhancing the opportunity for sustainable urban development. Also, it complies with John Elkington’s triple bottom line (TBL), or what is often referred to as the three “P’s”: people, planet, and prosperity8. Likewise, worldwide, large cities are applying guidelines to guarantee that environment, economics, and sociality are at the lead of urban design. The elevation of healthier streets has formed new chances for social and commercial interaction and more comprehensive outcomes9. Overall, it is the transformation of the earlier global Coalitions of Ecomobility that aims at engaging public and private sectors, promoting and advocating Ecomobility at a worldwide level in Industrialized and developing countries.Streets’ designA potential approach to fostering pedestrian Ecomobility is the streets’ design, which is a core focus of this research. Urban spaces are a vital city part, forming the basic structure of public life. Specific urban planning and design criteria make these spaces “quality public spaces”10. In this perspective, determining and evaluating these criteria will transform those public urban spaces into quality spaces. The last research adopted criteria that came to a head in the relevant reviews and were accepted by most researchers. Also, in the current research, the study chose following these criteria since they have been collected and validated by several researchers over decades (around 17 references; Table 1), and cover the possible aspects of successful streets; they will be presented and used in the next section (Methods).Table 1 Respondents’ statistics (N = 257).Full size tableA noteworthy point is the gap between municipal policies and the guidance provided to street design decision-makers. A study across cities in the United States highlighted some issues regarding the mechanism of developing policies related, as they aim to challenge auto-centrical street design standards in favor of “complete streets,” which are safe for users of all abilities. Also, they address the demands of non-motorized street users and sustainable transportation. Moreover, those policies do not lead to the negotiation of tradeoffs among users inside the street right-of-way; They are broad and defer to optimistic safety goals accommodating all user types equally without recognizing the accommodation’s implicit hierarchy11.Also, the transformative potential of experimentations proposed attaining “streets for people” rather than “streets for traffic” remains under-investigated. There is little to no comparative assessment of already present trials and no critical reflection on their explicit added value for systemic change. While street research aims to create basically diverse arrangements of urban mobility, their potential as triggers of a larger systemic change is blurred12.In the age of autonomous vehicles (AVs), a study reached that with the promise of Avs, which will use less street-right of way and uncouple parking from land uses in the cities; it is time to take back streets and make them serve people first, arranging cycling, walking, and transit. This action will take place precisely in the design process for livable streets. Also, it is time to act and make sure that designers and planners can get at the forefront of the rapidly changing technologies of vehicles13.The street design process had a different approach through medical and psychological professionals. According to the Irvine-Minnesota audit, expert observers calculated street users for four streets, which differed in walkability. From 7 am to 7 pm all days, the whole streets had significant quadratic trends of increasing followed by decreasing use. Furthermore, the two most walkable streets showed substantial linear increases in users across the day. Part of a street’s identity is its temporal activity rhythm, and both walkability and rhythms can report to urban design and restoration14. The study, through its test, searched what makes streets and neighborhoods walkable and found that more walkable streets had more users overall and linear increases in use starting from morning to early evening.This paper focuses on Ecomobility in Riyadh city streets that promote the integration of passenging, cycling, wheeling, and walking. A previous study discussed the pedestrian mobility status in the same city, focusing on the transformation to sustainable mobility. That research case study was applied to the PSU community and argued that the current mobility is unsustainable, as it profoundly relies on privately-owned cars run with fossil fuel. It unveiled that a substantial percentage of the survey sample (72%) traveled by car from home to the campus. However, the assessment results showed that the transformation to sustainable mobility is expected soon by launching the new mega projects related to public transportation like Riyadh Metro and busses, which is considered a key indicator of sustainable mobility15.Riyadh city in Saudi Arabia is a part of a hot-weather zone (almost 7 months a year: April–October), as seen in Fig. 116. As a result, studying the pedestrian thermal comfort affected by street design is a core point. Almost similar conditions were present in a case study in the Australian North Melbourne (southeast) at street level for pedestrians (Subtropical Zone), as seen in Fig. 217. That study assessed modeled existing and future scenarios for different street profiles and the consequences of microclimatic parameters and thermal comfort. The target was to assist urban planners in developing policies that can efficiently reduce the exposure to heat stress at the pedestrian level18.Figure 1The climate in Riyadh16.Full size imageFigure 2World climate zones17.Full size imageA comparison study was also applied to two gulf cities that share the hot weather: Dubai and Abu Dhabi. It compared the efficiency of the early suburbs and the newer ones to provide quick and direct access to destinations (connectivity). The study argued that better connectivity is required for usefulness in hot, dry regions. In this regard, it explored how the abandoned system of alleys could be cultivated to enhance connectivity efficiency19.In residential streets, developers’ width is not a choice but somewhat a constraint enforced through planners’ concluded subdivision standards. Residents can generally compromise by choosing smaller yards or homes in a swap for other facilities or a lower price, but they cannot select a smaller street20.Recently, in Riyadh city, a study highlighted that the rising fuel prices would create a positive atmosphere for implementing the complete streets’ concept, defined as streets’ design that can safely accommodate all transport modes for all society segments. It includes, but is not limited to, public transportation, humanizing neighborhoods, and promoting walking as a healthy lifestyle21.Research problemLacking the dependency on the Ecomobility traveling modes (as mentioned in the results) leads to poor health conditions, air pollution, noise, high greenhouse gas (and CO2) emissions, higher expenses, and excessive energy consumption.Research questionsThe study is seeking through its parts to answer the following questions:

    1.

    What are the reasons behind the lack of using the ecomobility means of transportation by the community?

    2.

    What are the community responses for the transformation to ecomobility if the reported barriers are removed or minimized? More

    The loneliest trees: can science save these threatened species from extinction?

    Perched among the fronds of the world’s loneliest tree, Viswambharan Sarasan had an important decision to make. Sarasan had worked for years to get access to this palm — the last living member of the species Hyophorbe amaricaulis, which grows in Curepipe Botanic Gardens, Mauritius.He reached up towards a cluster of its walnut-sized, olive-green fruit. Sarasan, a botanist at the Royal Botanic Gardens at Kew, near London, had been through sensitive negotiations for permission to take the fruit, each with one crucial seed inside. He then had to wait for the tree, nicknamed the lonesome palm, to produce them. Nine metres up, 50 fruit dangling within his grasp, he had to decide how many to take: enough to give himself a chance of culturing them back at Kew, while leaving enough for local scientists to work with.“It was the only shot I could get,” he says of his visit in June 2006. “But I didn’t want to take all the seeds and then it turns out badly.”He picked ten fruit. It was not his lucky number.When the plight of trees gets publicity, deforestation is generally the reason, but it is not the only crisis they face. Nearly one-third of trees — more than 17,500 species — are threatened with extinction. This is more than twice the number of threatened mammals, birds, amphibians and reptiles combined1. Mass plantings of trees, paradoxically, often add to the problem by using single species. Now, hundreds of plant conservationists globally are fighting to save the trees speeding towards extinction.“We shouldn’t be giving up on any tree species,” says Paul Smith, head of Botanic Gardens Conservation International (BGCI), a London-based charity that co-leads the campaign to secure the future of the world’s threatened tree species.But time is short, the obstacles are formidable and both climate change and fashions in ecology are moving against them.Peter Bridgewater, a specialist in biodiversity governance at the University of Canberra, Australia, says that finding a natural home for every tree species is impossible because climate change is altering ecosystems so fundamentally. Scientists who think this goal is realistic are “living in their own cloud cuckoo land”, he says.

    Neglected trees Inextricably linked with the problem of climate change, and equally as damaging, is the disappearance of species from Earth. The rate of extinction is at historic levels and accelerating, with around one million animals and plants under threat.The plight of trees can get lost among the tales of endangered mammals or birds. To get trees more visibility, in 2016 the BGCI, working with the International Union for Conservation of Nature (IUCN), organized the largest conservation assessment in the IUCN’s history: the Global Tree Assessment. Hundreds of plant conservationists searched rainforests, mountains and strife-torn regions, sometimes with no more than a crinkly herbarium specimen or the testimony of a long-dead explorer to guide them.In a 2021 report, they announced that they had found 58,497 tree species, of which 17,510 were threatened2. Since then, almost 2,800 of those have been labelled as critically endangered. Some 142 species are thought to be extinct in the wild (see ‘Trees under threat’). This year, a separate group of modellers estimated that a further 9,000 tree species are undiscovered3.

    Source: Ref. 2

    It is not just the number of trees, but also their diversity that matters. A single species can be the foundation of an entire ecological network, and its disappearance could cause a cascade of extinctions that might lead to an ecosystem collapse.Strong, diverse ecosystems are also better at sequestering carbon, says Jean-Christophe Vié, director-general of the Franklinia Foundation, a private organization in Geneva, Switzerland, that funds tree conservation and supports the Global Tree Assessment. No tree species should be viewed as dispensable, says Vié, because it would set a precedent for every developer, farmer or logger to justify removing any threatened tree.But tree conservation has become lost in international biodiversity targets — partly because trees get subsumed into general plant-conservation goals, and because plants are generally less showy than birds and animals. Trees need to be assessed for ecologists to champion them, says Malin Rivers, head of conservation prioritization at the BGCI.“If you look at mammals, birds, reptiles, they have data to bring to the table when there is a policy discussion,” she says. “Taxonomy gives the species a name; conservation assessment gives it a voice.”Protect and propagateArmed with the Global Tree Assessment’s catalogue of threatened species, conservationists have begun prioritizing species and taxonomic groups. The best approach, says Smith, is to protect vulnerable trees in their natural habitats. If that’s not possible, researchers try growing them from seed in a laboratory, greenhouse or botanic garden.The Global Tree Assessment revealed that nearly two-thirds of threatened trees are found in areas that are already protected, and stressed that one important task is to strengthen or expand these havens.That might mean controlling grazing, implementing a national logging ban for a particular species or establishing plots on which the tree can be cultivated for fruit or flowers without harming the larger population. On the eastern Caribbean island of Dominica, for instance, where harvesting resin for incense was killing lansan trees (Protium attenuatum), a tweak to the tapping method has halted the damage.Sometimes, however, so few trees are left that protecting an area isn’t enough.

    In Tanzania, seed-biology specialist Fandey Mashimba works with a tiny population of a towering species called Karomia gigas. These trees, with their large oval leaves and distinctive, papery fruit, were thought to have gone extinct in the 1980s, but around six of them were discovered in 2011 by botanists from the University of Dar es Salaam. Protecting the habitat isn’t enough, because a fungus destroys their immature fruit. Mashimba, who oversees seed production for Tanzania’s Forest Service Agency, tries to whisk the fruit away before the fungus infects them, to sterilize and multiply the seeds for planting.Mashimba and his colleagues tried germinating hundreds of K. gigas seeds. The result: just three treasured plants, which Mashimba monitors through his office window as their giant leaves wave in the breeze. In 2018, the forestry service also dispatched 6,000 fruit to the Missouri Botanical Garden in St Louis. There, botanist Roy Gereau oversaw the extraction and cultivation of 24,000 seeds. The seeds produced only 30 plants. Last year, one sapling unfurled a small, pale purple flower, which perished within a day. When two trees flower simultaneously, botanists will attempt cross-pollination.

    Mashimba is lucky in one respect: at least K. gigas produces seeds. Some trees produce none because their pollinators are gone; sometimes only one sex of a tree remains. For instance, most of the surviving specimens of the catkin yew (Amentotaxus argotaenia) in southern China are male. After a global search, a single female was discovered in the Royal Botanic Garden Edinburgh, UK; scientists there dispatched cuttings for planting near the surviving males. When they flower, reproduction can begin, says Gunter Fischer, a restoration ecologist at Missouri Botanical Garden. But this could take 30 years.Even if scientists do manage to acquire seeds from trees that are near extinction, germinating them can be tricky. Some go into dormancy, a protective state that, depending on the species, might be broken only through heating, cooling or scarring. Natural dormancy can last for years. Scientists try to circumvent it by culturing the embryo — the small section of a plant seed that will become the roots and stems — in a process known as embryo rescue.Every trick in the book The lonesome palm in the Curepipe Botanic Gardens — elderly, damaged and spindly — has seed problems, germination problems and more. It has resisted multiple rescuers since the 1980s. One obstacle is that the palm produces male and female flowers at different times, to avoid self-fertilization. Using a ladder and a brush, scientists override this process to collect, store and transfer pollen.It was the fruit of one such assisted-pollination project, each containing a single seed, that Sarasan carried back to Kew in 2006. He knew that lonesome palm seeds don’t grow if they are planted, so he used embryo rescue. With so few seeds, he felt there was no scope for experimenting with different culture media, so he made his best guess as to which blend to use.“I was so protective,” he says. “It was the responsibility, the excitement and also the fear of losing it.”The plantlets grew to 25 centimetres long. Then, one day, their fine white roots turned brown and they died, doubtless because of some nuance of the culture medium, he says.Other efforts have been derailed by mishap. In 2010, Kew horticultural scientist Carlos Magdalena negotiated to collect some freshly picked palm fruit while he was visiting Mauritius. Owing to a misunderstanding, two of the five fruit stored in a nearby fridge were eaten by a garden labourer who did not know their significance. Back at Kew, the seeds from the others failed to germinate.The failure rankles with Magdalena, who has a string of plant rescues to his name. As he roves the Kew greenhouses, steamy sanctuaries for plants that are bereft of a place in the wild, he sometimes feels he is all that stands between a species and its permanent loss.José Luis Marcelo Peña knows how he feels. In 2018, Marcelo Peña, a taxonomist at the National University of Jaén in Peru, was trekking through a steep, parched forest in Peru’s Marañón valley when he discovered a tree with light green flowers: Pradosia argentea, thought to be extinct.“It was a unique happiness that cannot be described,” says Marcelo Peña. Surveys yielded 200 more trees in the area, all of which were imminently threatened by agriculture.COVID-19 lockdowns began just as he attempted to save them. Without university facilities, but with remote help from the BGCI, he extracted 400 seeds from the purple fruit at home. More than 60 germinated: 20 survived. The following year, he tried again using fresh seeds, but a fungus got them all.As he finishes his story, he removes his glasses to wipe tears away. “It’s a big responsibility,” he says. And even with 20 little successes in the nursery, Marcelo Peña is concerned about the next step — reintroduction to the wild. Local people were unaware of P. argentea until recently, he says. They now support protecting the remaining trees — but they also need space to farm, which could put those survivors at risk.Back to the wildThriving in the wild is a distant dream for K. gigas, too. Tanzania’s forest agency and its partners are developing seed-propagation sites and nurseries for the species. But its future is uncertain, mostly because new trees could succumb to the same mysterious fungus.“We might have to content ourselves with saying, well, we have these lovely creatures in the zoo,” says Gereau.

    Reintroductions can be spectacularly successful, however. The BGCI highlights a project on Malawi’s Mount Mulanje, the only natural home of the cypress Widdringtonia whytei. In 2019, just seven mature trees remained, the others victims of illegal felling. By 2022, thanks to a collaboration with Malawi’s Forestry Research Institute and local people, the slopes are alive again with 500,000 seedlings, and many locals now make a living through this endeavour.Propagation itself turned out to be fairly simple, says Smith. In Mauritius, by contrast, ecologists have a tougher task. The Mauritian Wildlife Foundation, with help from botanists elsewhere, is attempting to save multiple critically endangered species at once, but success at propagation varies widely. There have been some dramatic restorations, including of some species from which only a single tree remained. But the lonesome palm, now part of this project, continues to resist.

    A fourth attempt has begun. Nets hang around the tree to catch the male flowers and store their pollen for hand fertilization when the female flowers appear. In France, botanist Stéphane Buord at the National Botanical Conservatory of Brest hopes to overcome the problem that faced Sarasan — too few seeds — by tapping into the large quantities of seeds produced by Hyophorbe vaughanii, a close Mauritian relative of the lonesome palm. He and his team have spent years working out a complex technical protocol that coaxes its embryos into rooted seedlings that survive outside a test tube. Now he is waiting to try this approach on the seeds of the lonesome palm.If he succeeds, the palm might eventually be reintroduced into a national park or into the wild. Kersley Pynee, a conservation scientist at the Mauritius National Parks and Conservation Service, has reintroduced other trees and shrubs and says it is an uphill struggle. Plants can fall victim to fungi, pests and other assailants. After one recent planting of 1,000 seedlings of the flowering shrub Nesocodon mauritianus, just 5 now remain, he says.This is to be expected, says Smith. In nature, trees produce vast quantities of seeds, of which only a fraction germinate and survive because of natural dangers such as infestations, fire or competition for light or nutrients.Tree museumThe Global Trees Campaign has so far planted out hundreds of thousands of seedlings from 300 threatened tree species. But for trees that can no longer survive in the wild, the only other options are to keep a specimen in a living collection, or to store its seeds in a bank.One target of the 2011 Global Strategy for Plant Conservation, part of the Convention on Biological Diversity, was to conserve at least 75% of threatened plants in living collections or seed banks by 2020 — a goal that has not been met. What’s more, simply drying and freezing seeds doesn’t always work. Technologies such as cryopreservation — fast freezing at ultra-low temperatures — could offer an alternative, although it is expensive and impractical for many countries. And in 2018, conservationists warned4 that the seeds of one-third of tree species cannot be banked, largely because they don’t survive drying.Smith rejects this bleak diagnosis. Between seed banks, cryopreservation, nurseries, botanic gardens and arboreta, there are plenty of options to “buy us time”, he says.One trend that could help is mass tree-planting, in which governments and corporations plant trees to sequester carbon to meet emissions targets. Done badly, as many of these projects are, mass plantings can destroy biodiversity. Done well, they could rescue many species, says Smith. “This is a bandwagon we really need to jump on.”

    To help boost the usefulness of such projects to biodiversity, the BGCI and its partners have drawn up a certification programme for tree-planting projects called the Global Biodiversity Standard.Species conservation could also piggyback on the growing ecosystem-restoration movement. There are now more than 100,000 of these projects globally, helping ecosystems to capture carbon and provide essential services.Smith argues that including native species strengthens such projects. But restoration ecologists are often more concerned with overall function than with individual species, says Curt Meine, a historian of ecology at the Aldo Leopold Foundation in Baraboo, Wisconsin. And they want ecosystems to provide multiple services to humans, including sustainable livelihoods. Some acknowledge that tree conservation should have a place. “I do think it’s important work and we could learn a lot,” says Robin Chazdon, a restoration ecologist at the University of Connecticut in Storrs.But there are more threatened tree species than there are restoration projects to absorb them. “It’s not going to be the way of protecting all of those tree species,” she says.Some ecologists have deeper concerns. Bridgewater says that the efforts of conservationists and of restoration ecologists don’t factor in climate change.“They all in the end assume that nothing is going to be changing,” he says. But many trees, and whole ecosystems, just won’t survive in their current ranges, he says.“You could save every tree species but it will not be what people think — it will be in botanical gardens and larger managed conservation areas, and planting where it’s suitable for survival, not where it’s currently growing.”But the tree saviours are driven by something visceral: panic at the permanent loss of the rich, unique, irreplaceable and often-undeciphered identity of each species.“I don’t feel I am, as a humble human, here for a few decades on this planet, authorized to just cut off millions of years of evolutionary history,” says Vié. “Every species has a value.” More

    Analysis of the impact of success on three dimensions of sustainability in 173 countries

    Our study method includes the following stages: (1) framing the investigation problem, (2) examining the literature, (3) developing and verifying two hypotheses, (4) collecting data, (5) the multiple criteria examination of 173 countries by means of the Degree of Project Utility and Investment Value Assessments (INVAR) method, (6) calculating correlations between 33 indicators and the success of 173 countries, (7) building 12 regression models, (8) compiling eight Maps (of which seven are CSS Maps) visualizing national success and sustainability, (9) spatial perspective analysis, and (10) performing integrated linear regression, multi-variant design and multiple criteria analysis of national policy alternatives, in order to identify rational decisions.This research is a quantitative study to examine the way national success affects 12 indicators of the three dimensions of sustainability in 173 countries, and uses the data from 2020, or the latest available.As investigation methods, our CSS Maps and Models can make it easier to study interdependencies between country success and sustainability. Supplementary Section 1, 4, and 5 presents our literature analysis which is carried out to gain deeper insights into our CSS Maps and Models, and to better understand their components in the worldwide research context.The following two core hypotheses have been proposed and verified for this research:

    Hypothesis 1—The increasing success of a country is generally accompanied by increasing values for the three dimensions of sustainability indicators, and declines in these indicators lead to decreases in the country’s success. Improving some sustainability indicators tends to improve other sustainability indicators.

    Hypothesis 2—Changes in the number of countries and their traditional key indicators system do not make a very significant difference to the relative national sustainability and success values. Likewise, the boundaries of the seven country clusters discussed in this research do not excessively depend on specific traditional key systems of indicators used in their analysis.

    Along with different sets of national 17 success (Supplementary Table S1) and 12 sustainability (Supplementary Table S2) indicators, the INVAR method46 (Supplementary Section 2 and Fig. S1) was used to measure and map the success of the 173 countries selected as the focus for this research. The traditional statistical indicator systems defining country success and the three dimensions of sustainability are based on studies from various countries analyzed and combined. The INVAR method calculates an integrated criterion characterizing the overall success of the countries. This integrated criterion is directly proportional to the relative effect the values and weights of the given criteria make on the country’s success. The multiple-criteria INVAR analysis method has been applied to various countries, including Asian nations47, ex-Soviet states48, and a group of 169 countries49.This research used data from the framework of variables taken from various databases and websites, including Transparency International, Global Data, Eurostat-OECD, the World Bank, Knoema, the World Health Organization, Global Finance, Freedom House, Heritage, the Global Footprint Network, Socioeconomic Data and Applications Center, Our World in Data, Climate Change Knowledge Portal (World Bank Group), and The Institute for Economics and Peace, as well as global and national statistics and publications. All 173 countries analyzed in this article are listed in matrices, along with their 17 detailed success (Supplementary Table S1) and 12 sustainability (Supplementary Table S2) indicators (systems of indicators, their numbering, values, and weights). The INVAR method46 was applied to perform multiple criteria analysis of the 173 countries, and the results are presented in Supplementary Table S1 and Figs. 2, 3, 4 and 5. We use equal and different weights of 17 indicators to calculate the deviation of priorities for the 173 countries, which stands at 5.34% (Supplementary Section 2 and Fig. S2).Along with different sets of 12 national sustainability and 17 success indicators, the INVAR method46 was used to measure and map the success of the 173 countries selected as the focus of this research. The traditional statistical indicator systems defining country success and the three dimensions of sustainability are based on studies from various countries analyzed and combined. The INVAR method calculates an integrated criterion characterizing the overall success of the countries. This integrated criterion is directly proportional to the relative effect the values and weights of the given criteria make on the country’s success.Supplementary Table S3 shows the correlations between all measures determined by analyzing 173 countries. Supplementary Table S4 reveals the correlation coefficient matrix of the 17 success criteria for each of the 173 countries analyzed in this survey.Along the vertical axis y we analyze seven sustainability indicators, and along the horizontal axis x we analyze the success and priority indicators (9 CSS Map dimensions). The median correlation between the survival versus self-expression values and the nine CSS Map dimensions (the x-axis and y-axis) is moderate, whereas the median correlation between the traditional versus secular–rational values and the nine CSS Map dimensions is strong (Fig. 1).Tables S5-S8 show the descriptive statistics of 12 CSS Models (Supplementary Section 3). Supplementary Table S8 shows the extent to which a 1% increase or decrease in success of country’s features can push sustainability indicators up or down, expressed as a percentage. Supplementary Table S8 also shows the degree to which the percentage changes of success or the values of country’s features explain or fail to explain the dispersion of sustainability indicators. These CSS Models (Supplementary Section 3) show that when a country’s success increases by 1%, its 12 indicators related to the three dimensions of sustainability improve by on average 0.85% (Supplementary Table S8). Furthermore, the 17 variables of country success used in the CSS Models explain 80.8% on average of the dispersion of the three dimensions of sustainability and 98.2% of the dispersion of the country success variable (Supplementary Table S8).An increase of 1% in a country’s success is accompanied by a 0.39% average increase in its social and environmental (0.84% on average) sustainability indicators (Supplementary Table S8). On average, the CSS Sustainability Models explain 76.3% of the dispersions among the environmental sustainability indicators, 83.4% of the dispersions among the social sustainability indicators, and 94.5% of the dispersion among economic (i.e. the gross national income per capita) sustainability indicators (Supplementary Table S8).The study produced the eight Maps (of which seven are CSS Maps) of the World based on an analysis of 99–150 countries (the 2020 Inglehart–Welzel Cultural Map of the World focused on 103 analogical CSS Maps countries). The two dimensions of country success on the CSS Maps are represented in a system of 17 variables (Supplementary Table S1). When a country’s success grows, its performance related to the three dimensions of sustainable development increases as well, and the eight Maps (of which seven are CSS Maps) clearly illustrate this relationship (Figs. 2, 3, 4 and 5). The CSS Maps of the World developed as part of this study are described in Supplementary Section 5.Studies from various countries and our research suggest that country success and their features (x-axis) and sustainability indicators (y-axis) are generally strongly interrelated, and move in the same direction over time. This means that successful countries also perform better on sustainability dimensions.Stage 9 involved analysis of the spatial perspective research in place for explaining and predicting globally recognised physical, spatial, and human patterns in multiple ways. We apply 12 CSS Models, alternative design and multi-criteria analysis methods for spatial perspective analysis (Supplementary Section 4).The following additional two research objectives were set: (1) to determine the impact of a country’s success factors on sustainability metrics, and (2) to offer stakeholders recommendations regarding the strategies for improving sustainability indicators. The ways to improve sustainability indicators are determined by analysing 17 dependent variables (the main paper section “Practical applications and implications”, Table S9). As previously mentioned, in stage 10, national policy options have been examined by means of integrated linear regression, multi-variant design and multiple criteria analysis to identify rational decisions. Analysis of multiple alternative options and their detailed indicators, with a consideration of the existing state of the micro, meso, and macro environment, can ensure rational country success and sustainability. Below, a brief analysis of several best global practice examples of ways to identify rational policy, activities, and strategy follows. The examples presented below suggest that multiple possible alternatives must be designed, assessed against a system of micro, meso and macro indicators, and the most effective options selected to make countries more sustainable. In Isham and Jackson’s14 opinion, materialistic lifestyles and values have been associated with adverse effects on human health as well as having detrimental effects on our planet. Therefore, activities and lifestyles should be identified that promote human well-being, yet which at the same time protect ecological security. Isham and Jackson14 identify optimal activities (arts and crafts, reading, sports, meditating) with high levels of human well-being and low environmental costs. It is important to estimate pollution impacts on health in order to come up with the right policies for better health outcomes. Yet, the task is challenging because economic activity can lead to worse pollution, but can also improve health outcomes in its own right37. Humidity, temperature, dispersal by the wind, and other environmental factors contribute to pollution levels. Certain fine particulates can stay in the atmosphere for days, and travel long distances to be inhaled in places far away from the source, even in other continents. Local conditions must be reflected in emissions-control policies, and the global flows of air pollutants must be taken into account6. The explanation for the phenomenon of demographic transition could be improved public health in developed countries which results in a move toward a slower life strategy38. Studies show that children from wealthier backgrounds undergo puberty later than those from poor socio-economic backgrounds. Early puberty can lead to a variety of health problems and a shorter life. By the early adult years, the effects of exposure to trauma, post-traumatic stress disorder, and other conditions can become apparent in the form of diseases related to aging9. Education is a very important factor in economic growth, and is also strongly related to health. In addition to health benefits, substantial increases in education, especially of women, and shrinking gender gaps have an important effect on the roles and status of women in society36.The INVAR method, statistical analysis, and the CSS Maps and Models can help generate multiple policy recommendations for various stakeholders. The possibilities are as follows:

    To create alternatives for ways to develop country success and sustainability, by performing countries’ multiple criteria and statistical analysis and identifying decisions that would be rational;

    to perform quantitative and qualitative analysis of the existing data and to interpret it. The results obtained this way would prompt automatic recommendations designed for different stakeholders on ways to improve country sustainability. More
