To what extent can rooftop gardens and flower meadows in cities increase the biodiversity of natural ecosystems in cities?
Given the ongoing climate change, including global warming, air pollution, limited areas of urban parks and other green spaces, gardens, flower meadows established on the roofs of buildings in cities can significantly increase the areas of urban green space. When urban green areas are significantly expanded, the biodiversity of natural ecosystems in cities can also increase significantly. In addition, additional green areas can have a positive impact on the air quality of cities. Air quality is not only a question of pollution levels, but also humidity levels and summer temperatures. Additional green spaces can play an important role in the rest and recuperation of residents, which can translate into improved health for people living in the city. Additional green areas, including gardens and flower meadows, also mean more foraging areas for insects, including pollinating insects, whose numbers are rapidly declining due to the over-chemicalisation of agriculture. Besides, additional green areas in cities can increase the level of sustainability in terms of sustainable development, green building and environmentally and climatically sustainable urban agglomerations.
In view of the above, I would like to address the following question to the esteemed community of scientists and researchers:
To what extent can gardens and flower meadows established on the roofs of buildings in cities increase the biodiversity of natural ecosystems in cities?

In recent years, there has been development of some innovative construction technologies that are changing the way we build. There are many new technologies that will have a significant impact on the future of the construction industry.
Today, construction companies are able to complete projects more quickly and efficiently than ever before. There are new technologies in demand for the future that will help with accuracy, sustainability and faster construction.
Based on your point of view, what are the types of construction that can be used in future?
Relevant answer
Answer
Dear Shuraik Kader,
In view of the increasing risk of an energy and climate crisis, eco-innovation-based, green building technologies will be developed in the future to build homes that are significantly more energy-efficient and resistant to the negative effects of climate change. Consequently, the future will mainly develop pro-environmental, energy-efficient sustainable construction. Perhaps it will also be environmentally neutral construction based solely on natural building materials.

Thermal mass is a property of construction materials to absorb, store, and release heat energy. It is an important element of passive solar house design and can be utilized for passive solar heating, passive solar cooling, or both. I would like to know, what is the most effective technique to quantify these kinds of thermal masses in an existing construction?
Relevant answer
Answer
The simple muiltiplication of the mass by the thermal capacity as Bachir Achour proposes, is valid only at thermal equilibrium. Since buildings are always in a thermally dynamic state, this method strongly overestimente the active thermla capacity. When the ambient temperature continuously changes, the calculation is more complex, and needs solving the equation of heat. Simple mathematical solutions to determine the thermal mass of a multilayer plane building component under dynamic conditions are indeed described in EN-ISO 13786 as mentioned by Edwin Rodriguez-Ubinas.
An experimental method to determine the dynamic thermal capacity of a room was proposed by Van der Maas (see attched paper). The apparent room effusivity can be measured by recording the increase of the indoor temperature after switching on a constant power heat source.

Dear Leila,
Yes, I agree with your thesis that the development of smart cities will significantly improve people's quality of life, because modern infrastructure and amenities mean fewer development, system and infrastructural constraints. In my opinion, the development of smart cities should take into account the implementation of the principles of environmental policy, sustainable development goals and the green circular economy. Therefore, the development of modern cities should follow the model of sustainable, pro-environmental smart cities.

Zillow may be a useful source for current values. Depending on your timeframe, tax assessment records -- generally available for free -- can be useful, but they have a large amount of lag. Hence the reason to tap Zillow or similar for recent data. But Zillow is labor-intensive, requires looking up individual addresses. Zillow & assessor files also give you housing characteristics that you will need. Economics journals contain numerous studies of impacts on property values, eg, of firearm injury/crime rates, noise, pollution. Many are fraught with problems.

What are the examples of eco-innovations that can significantly reduce the scale of environmental pollution and reduce greenhouse gas emissions and slow down the faster global warming process?
Currently, the problem of growing garbage with unsorted waste is ignored in many countries, but because in the future the negative aspects of the problem of environmental pollution, including plastic, will grow, so in the future other countries will also try to solve this problem.
The problem of environmental pollution with plastic waste is one of the key global problems. This problem should be solved in all countries, and above all those that "generate" the most. The European Union has already undertaken specific measures in this direction, eg by introducing legal regulations under which plastic will be withdrawn from packaging by 2021 and replaced with biodegradable materials such as vegetable origin. However, these regulations concern only European Union countries.
Similarly with other aspects of environmental pollution and greenhouse gas emissions. Also, some large global economies are currently ignoring growing problems. But such an approach must be quickly changed, because there is little time to implement pro-ecological reforms, primarily in terms of reducing environmental pollution and reducing greenhouse gas emissions.
As regards the reduction of greenhouse gas emissions, it is necessary to reform the energy sector in such a way as to switch from the production of electricity based on the classic energy based on the combustion of minerals to technologies based on the development of renewable energy sources. In addition, it is also important to develop electromobility in the automotive industry and other types of transport.
The global warming process is progressing faster, the scale of the negative effects of climatic disasters and weather anomalies, which are a consequence of the ever-faster global warming process, is increasing. There is little time left, according to climatologists only max. over a dozen years to implement the necessary ecological reforms and innovations, including in the area of energy development based on renewable energy sources, to stop or even significantly slow down the ever-faster global warming process.
In addition, one of the main types of eco-innovations includes innovative technologies for building zero-energy houses and residential buildings. The special design and materials used ensure low energy consumption and closure of the energy cycle in a cycle in which household power plants generating heat and electricity based on renewable energy sources are an integral part, primarily through the use of photovoltaic panels and wind farms.
As part of the implementation of the necessary pro-ecological reforms, it is also necessary to develop eco-innovations that will improve the automation of waste segregation and recycling processes. In addition, it is also important to create innovative technologies for the creation of new biodegradable materials that will replace plastic in packaging.
A good solution is the use of packaging made of biodegradable materials of origin, eg vegetable, on the basis of raw materials in the form of crops. These types of packaging could be consumed after their use, such as plates and cutlery made of rice or other cereals, or could be processed into compost for animal feed or for fertilizing arable land, or for incineration in a specially built incineration plant.
In connection with the above, the increasingly common application of ecological innovations, which are necessary to reduce greenhouse gas emissions and to limit, slow down the faster global warming process, will also contribute to increasing the scale of sustainable green economic development realized according to the green economy concept.
These processes of implementation of ecological innovations and implementation of pro-ecological reforms should be conducted in all countries, and to the largest extent in developed and developing countries, industrialized countries, including the largest economies in the world, which are the largest emitters of greenhouse gases and producers of garbage and non-degradable waste, toxic or hardly degradable.
Do you agree with me on the above matter?

On 1.11.2021, Earth, which is very important for the future of our planet, began at the UN Climate Summit COP26 in Glasgow, Scotland. A little earlier, i.e. during the G20 summit preceding the Glasgow summit, the target of reducing CO2 emissions was set so that in the current 21st century the temperature increase would only reach 1.5 degrees C. Based on scientific research and predictive models, it is estimated that 2.7 degrees Celsius, the temperature of the atmosphere will increase, even if all the previous Paris decisions and the previous COP climate summits are implemented, it is too much. It is necessary to urgently create further ecological innovations and capture CO2 from the atmosphere so that the increase in the temperature of the atmosphere at the end of this century stops at 1.5 degrees C. Until now, the temperature of the atmosphere has increased by 1.1 degrees Celsius compared to the pre-industrial era. It is necessary to urgently create and implement new pro-environmental innovations and ecological technologies, thanks to which the green transformation of the energy sector will be fully accomplished during the present decade of the 1920s. Only in this way will the increase in the temperature of the atmosphere along the current path of growth, estimated at around 2.7 degrees C at the end of the 21st century, be significantly reduced and we will avoid the climatic Armageddon at the end of this century.

Dear Stephen Poon,
Yes, unfortunately there is no single global strategy for the concept of a smart and sustainable city as well as programs supporting the development of pro-environmental business ventures, under which agglomerations would be built and / or expanded in accordance with the concept of a smart and sustainable city. It is necessary to develop this type of programs under public-private partnerships, taking into account the issue of co-financing this kind of pro-environmental economic projects implemented in the field of construction, expansion of public infrastructure in cities and development of agglomerations in accordance with the implementation of the sustainable development goals.

Yes, in my opinion, sustainable pro-ecological economic development should be an important determinant of shaping economic policy. Do you agree with my opinion?
For many centuries, the economies of countries and enterprises have developed without knowing or ignoring the principles of sustainable pro-ecological development. On the other hand, in the 21st century the realities have changed, the global warming process is accelerating and if the reforms of pro-ecological changes, development of renewable energy, recycling development, development of environmental protection etc. are not implemented, in the short term the global warming process will become an irreversible process and at the end of the 21st century the planet Earth, humanity and many other forms of life on Earth are threatened by climatic extermination due to the high rise of negative anomalies and climatic cataclysms.
Sustainable pro-ecological economic development, now and in the future, can not be ignored further, it can not be considered a myth. Economics must change towards the concept of green economy. The economic policies of states should also change in such a way as to activate for the development of ecological innovations and support the processes of sustainable pro-ecological development.

The turn of the Earth's journey can no longer be stopped, and it is not because the sustainable social economy can become a PROGRESSIVE AND STABLE economic model, it is that there is no other option. The change has to take place "yes or yes". But setting achievable objectives in the short or medium term. These changes see that there is an existing model that must not be eradicated, but transformed, since the business sector has certain facilities and infrastructures and therefore still stable. You cannot close without a gradual transition process. Taking down and building again is not the solution. For example, there are sectors that seem to belong only to the "Memory of the past", but we can make the turn starting by thinking about the reuse and development of many of the abandoned or semi-abandoned Rural Sectors.

Answer
There are various types of pollution, so each one or combination may take a specific survey or inventory, and assessment. Some of the various types may include solid waste, sanitary waste (human, animals, pets, etc.), industrial wastes, air pollutants, water pollutants, soil pollutants, etc. Coming up with a working proposal would probably necessitate involvement of leaders, community, landowners, and others interested, such as industry, hospitality such as hotels, citizens, etc. Leaders might include political representatives, health, religious, agencies, police or enforcement, various technical pollution experts, etc. Funding to develop comprehensive plans, improvements and management as well as monitoring may be another important area to address. Plans or programs might be developed to help address specific types of pollution, or circumstances, and some of these might be voluntary citizen responsibilities, and some might be legalized or regulated, and funded by taxation, communities, industries, or government actions.

Sustainable development is very important in the context of the increasing use of resources and environmental pollution.
The basic issue that must be achieved within the framework of full sustainable development is the renewal of resources, reduction of economic growth to the optimal level ensuring renewable resources, reduction of environmental pollution, creation of biodegradable substitutes for fossil fuels, replacement of traditional energy based on mineral combustion for technological innovations in in the field of energy, including the development of energy based on renewable energy sources, etc. To this should be added a reduction in greenhouse gas emissions to slow down the negative aspects of the oceogenic climate of the Earth. There is so much to do in these themes and, above all, a great deal to do in the 21st century so that it would not be too late.'
To effectively carry out this process, it is necessary to develop universal, precise measures of sustainable development that will be used globally and will be recognized as the standards for assessing the process of achieving and achieving sustainable economic development in harmony with ecology.
But it is very difficult to establish precise measures for the sustainable development process. Sustainable economic development in correlation with ecology should be measured to determine if it is being implemented. It is necessary to define precise determinants that on one hand will determine the pace of economic development and on the other hand will take into account specific issues of ecology. It should be a set of quantified indicators based on selected measurable and quantitative data, so that the whole analytical process can be considered as a research objective method. The best solution will therefore be to develop an analytical scoring method, for which the basic components of this method will be defined economic and ecological quantitative indicators.
In the light of the above, the question arises: Is sustainable development possible taking into account the full harmony of economic development with ecology?
Even if it is unrealistic, what are the reasons for building a theoretical model that would present such a fully balanced development?

Dear Dariusz Prokopowicz the sustainability criteria must be the core of our efforts to maintain our course towards a climate-resilient low-carbon transition, rather than continue the vicious cycle of environmental degradation, biodiversity loss, and zoonotic infectious disease outbreaks. For instance, the world response to the COVID-19 pandemic must be focused on addressing underlying factors through the SDGs to recover prosperity and restructure our society in a healthier, safer, fairer, and sustainable path. The option for a brown recovery instead of investing in a sustainable growth will depend on how human society will deal with the emerging risks from the COVID-19 pandemic. Kind regards, Ernani

Why, despite the scientifically confirmed fact that the global warming process is progressing faster and faster in many countries, so little is done in terms of necessary proecological reforms and implementation of ecological innovations and development of energy based on renewable energy sources, development of electromobility, plastic reduction from packaging, improvement of waste segregation and development recycling?
Due to the accelerating process of global warming, it is necessary to increase expenditures on the development of eco-innovations, their industrial implementation and accelerate the implementation of necessary pro-ecological reforms, first of all development of energy based on renewable energy sources, development of electromobility, plastic reduction from packaging, development of biodegradable applications materials of organic origin, improvement of waste segregation processes, development of recycling, organic farming, zero-energy construction and other key aspects of sustainable pro-ecological development carried out according to the concept of green economy, etc.

Answer
From an epistemological point of view, it follows that the economic analysis of the object must complement, or better, be part of a sociological analysis of the object. Like economic sociology, the two approaches on this point are difficult to distinguish, socio-economics addresses the economic object. According to Campbell, 2003, at the international level, place of exercise of international financial institutions, the policies of insertion of developing countries into the world economy have mainly resulted in the promotion of foreign investment as a driving force. of growth. Thus, as a condition of access to loans granted by these institutions, the World Bank and the International Monetary Fund in particular, developing countries have had to open their economies to investment and international trade.

Although trees are part of the Urban Ecosystem, however: what is the possible role urban forests, peri-urban forests, large parks (e.g. Central Park), green belts, etc in urban metabolism towards sustainable cities.
Relevant answer
Answer
Cities are an integral part of the face of the Earth. Although they occupy only 2% of the land area, they are now home to half of the world's population. The main economic, scientific and cultural potential of society is concentrated in cities, so they play an important role in the economic, political and social life of each country individually and of humanity as a whole.
By 2025, the urban population will be 2/3 of the world's. More than half of the citizens live in cities with a population of more than 500 thousand people, and every year the share of the population living in large cities is growing.
Plants that grow in a large city are real "Spartans". The growth of trees here is very difficult due to environmental pollution. Up to 30 tons of various substances fall annually on 1 km2 of a large city, which is 4-6 times more than in rural areas. Scientists believe that a large proportion of deaths in cities around the world is associated with air pollution.
The main cause of photochemical fog is car exhaust gases. A car emits about 10 g of nitrogen oxide per kilometer. Photochemical fog occurs in polluted air as a result of reactions occurring under the influence of solar radiation.
Due to the harvesting of fallen leaves in autumn and snow in winter, in the cold winter period, urban soils are more emasculated and freeze deeper than in woodlands. All this negatively affects the state of the root system of plants.
But not only the microclimate worsens the life of plants in the city. The most important ecological factor in plant life is water. In cities, plants often lack soil moisture due to its runoff into the sewer network.
This explains the fact that the species composition of trees most often planted along roads and on streets is not too diverse. The main breeds in the middle zone are Linden, poplar, maple, chestnut, birch, larch, ash, Rowan, spruce, oak, and about 30 species of shrubs. The latter are often used to create hedges.
What is the role of green spaces in air purification? In the leaves of the tree, chlorophyll grains absorb carbon dioxide and release oxygen. In natural conditions, in summer, a medium-sized tree releases as much oxygen in 24 hours as is necessary for three people to breathe, and 1 ha of green space absorbs 8 liters of carbon dioxide in 1 hour and releases enough oxygen into the atmosphere to support the life of 30 people. Trees clear carbon dioxide from the ground layer of air about 45 m thick.
Among the various types of trees used for urban landscaping, chestnut has special properties. One adult chestnut tree cleans up to 20 thousand m3 of space from incoming exhaust gases.at the same time, unlike many other trees, chestnut decomposes toxic substances almost without harm to its health.
Poplar is also resistant to air pollution. In terms of the amount of carbon dioxide absorbed and oxygen released, 25-year – old poplar exceeds spruce by 7 times, and in terms of air humidity-almost 10 times. So to improve the air, instead of seven firs (three limes or four pines), you can plant one poplar, which also captures dust well.
The foliage of trees actively captures dust and reduces the concentration of harmful gases, and these properties are manifested in different breeds to different degrees. Leaves of elm and lilac (better than poplar leaves) retain dust well. So, planting of 400 young poplars during the summer season catches up to 340 kg of dust, and elm – 6 times more. Acacia, unpretentious fast-growing rosehip and a number of other plants also have similar properties.
On a hot summer day, rising streams of hot air are formed over the heated asphalt and hot iron roofs of houses, carrying with them the smallest particles of dust that remain in the air for a long time. At the same time, descending air flows occur over a Park located somewhere in the center of the city, because the surface of the leaves is much cooler than asphalt and iron. The dust carried away by these descending streams settles on the leaves of the trees of the Park. One hectare of stands of coniferous trees holds up to 40 tons of dust per year, and deciduous-about 100 tons.
In conditions of high air pollution, there are some changes in the phenology of plants, especially those that grow along highways. There is a reduction in the growing season, the timing of flowering and fruit maturation, the degree of flowering and fruiting, the quality and germination of seeds.
For the comfort provided by transport, for a huge number of cars, we pay for the cleanliness of the air. When 1 liter of fuel is burned in the car engine, 200-400 mg of lead gets into the air. In a year, one car can emit up to 1 kg of this metal into the atmosphere. Increased lead content in vegetables and fruits grown near highways, as well as in the milk of cows fed contaminated grass, is a danger to human health.
Sometimes in the summer you can watch the leaves falling from the trees. The reason for this is the high lead content in the air. Trees are hard to tolerate lead poisoning. The upper threshold of lead concentration for plants has not yet been established. Some plants, such as mosses and larch, absorb it in relatively large quantities, and birch, willow, and aspen – much less. By concentrating lead, plants purify the air. During the growing season, a single tree can accumulate as much lead as it contains in 130 liters of gasoline. A simple calculation shows that at least 10 trees are needed to neutralize the harmful effects of one car.
Green spaces play an important role in noise control. Trees planted between noise sources and residential buildings reduce noise levels by 5-10%. The crowns of deciduous trees absorb up to 26% of the sound energy falling on them. Large woodlands reduce aircraft engine noise levels by 22-56% compared to an open area (at the same distance from the noise source). Even a small layer of snow on the branches of trees increases the absorption of noise.
However, you can get the opposite results if you plant the wrong trees and choose the wrong breeds. For example, planting trees with a dense dense crown along the axis of a street with a busy traffic flow will act as a screen that reflects sound waves towards residential buildings.
Most effectively perform the noise protection functions of planting red elderberry, red oak, and canadian Irga.
Interestingly, the sounds are not absorbed by the leaves of trees. Hitting the trunk, the sound waves break, heading down to the ground, where they are absorbed. The best guardian of silence is considered a fir tree. Even at the most noisy highway, you can live in peace if you protect your home next to green fir trees. And it would be nice to plant chestnuts next to it.
Trees with wide crowns and shrubs planted along sidewalks improve the microclimate of streets.
Trees and shrubs (more than 500 species) emit volatile substances into the air – phytoncides that have the ability to kill microorganisms. Phytoncides, discovered in 1928 by the Soviet scientist B. p. Tokin, have a great impact on the life of plants, speeding up or slowing down their growth and development. Active sources of phytoncides are white acacia, birch, willow, winter and red oaks, spruce, pine, poplar, cherry, etc. It is especially important that phytoncides can kill some pathogens of human and animal diseases. Coniferous forests are harmful for pathogenic microbes. Scientists have found that the coniferous forest has 2 times less bacteria than the deciduous forest. For example, 1 ha of juniper releases about 30 kg of phytoncides per day. Pine phytoncides have a destructive effect on tuberculosis pathogens, and fir, poplar, and oak phytoncides – on diphtheria bacilli. Experiments have shown that in June-July, the phytoncides of common cherry suppress the reproduction of Salmonella, Shigella and inhibit the growth of Staphylococcus, and the phytoncides of Siberian larch suppress the reproduction of Salmonella and inhibit the growth of Shigella.
Tree and shrub plantations weaken the negative effect of winds. But dense planting of green spaces does not perform windproof functions, as it leads to increased turbulence of air flows.
Green spaces during the growing season increase air humidity and stabilize moisture exchange between the earth's surface and the atmosphere. In the shade of the garden on a hot day, the air temperature is 7-8 lower than in the open. If on a summer day the air temperature on the streets is above 30 €8C, then in a Park or square the thermometer shows only 22-24 €8C.
The greatest harm to green spaces in the city is caused by a constant lack of moisture as a result of the predominance of surface runoff over underground. Harmful effects on all types of plantings are caused by soil contamination, especially with heavy metals and salt used in winter to combat ice.
Underground utilities, especially heating and gas pipelines, significantly restrict the planting of green spaces along streets. And drains and sewers themselves are subject to destruction under the influence of tree roots. Therefore, when designing green spaces of streets, it is necessary to take into account the depth of underground communications (the zone of inaccessibility of the root system must be more than 3.4 m).
Trees and shrubs that grow in the city do a great job every day and every hour: they absorb dust and carbon dioxide, produce oxygen, perform sanitary, water protection and noise protection functions, form the microclimate and the peculiar appearance of the city.
The recreational value of green spaces is associated with the organization of optimal recreation. Squares, parks, playgrounds with a variety of plants and compositions, complemented by small architectural forms, decorative water elements (pools, fountains) contribute to the full recreation of the population. Green spaces serve not only as decoration, they are true defenders of people's health.

Answer
Actually, the standard was never reportd in the frame of WHO official docments. During the preparation of FAO Guidelines on urban and periurban forestry, we tried to find out the text referring to the cited standard but it was impossible. SO, the interpretation is like this. In 1968, Italy published the standards for urban development and 9 m2 was the figure for green spaces in new construction areas. Meanwhile, Italy team was quite active in WHO and there is a unoffical report from Italy to WHO board where is used the 9m2 standard. Then the success story of 9m2 began. In the last documents of WHO on public/green open spaces, they are strongly reccommended in the policies and planning actions of the cities but it is always reported an appropriate dimensional standard with the conditions of the cities where they need to be implemented. And I guess it is quite right like that: cannot compare Antofagasta in the Atacama desert to Bangui, in the equatorial forest.

Dear researchers,
I am looking for information how Oslo is financing the development of sustainable city transport (any reports, strategies?) Moreover how urban transport is changing in terms of green mobility (qualitative and quantitative data). I will be grateful for your contribution
Relevant answer
Answer
Joanna Oleskow-Szlapka As regards your discussion on financing the development of sustainable city transport, I have attached some useful materials for you (see attached files below). I believe these would be helpful. Moreso, I have a brief summary of the information you required, and the source / link is pasted for further readings.
Oslo has one of the most advanced public transportation systems in Europe. The metro, bus, tram and ferry networks are integrated and the zone-based fare system deploys the latest technologies. During the last five years, growth in public transport use has been about 29 per cent while the use of private cars has remained stable at the 2005 level.
Oslo is the capital region of Norway, a highly-developed and oil-rich country with a stable economy. The municipality of Oslo spans 454 square km and is located in the inner part of the Oslo Fjord in South Eastern Norway. The Oslo Region consists of 70 local authorities, including Oslo, Akershus, Buskerud and Østfold and the municipalities surrounding Oslo. It has population of about 1.8 million inhabitants.
Key players in public transport
Oslo Sporveien AS (Sporveien), erstwhile Kollektivtransportproduksjon AS (KTP), is the operator of the public transportation network in Oslo, Akershus, and Vest fold. The company is fully-owned by the city government and operates under contract with the public transport authority Ruter AS.
Ruter AS is the management company for public transport in Oslo and Akershus. It is owned jointly by the Oslo municipality (60 per cent) and the Akershus County Council (40 per cent). Ruter was formed in 2007, following the merger of AS Oslo Sporveier and Stor-Oslo Lokaltrafikk a.s, which were the public transport authorities for Oslo and Akershus, respectively.
Almost a quarter of the Norwegian population lives in the area served by Ruter. The 300 million public transport journeys a year by Ruter represent almost 60 per cent of all public transport journeys made in Norway. All public subsidies of public transport services in Oslo and Akershus, with the exception of state subsidies provided to Norwegian State Railways (NSB), are granted through Ruter.
Ruter has two subsidiaries:
  • Trafikanten, a wholly-owned Ruter company since January 2012, which aims to promote the use of public transport through information solutions for all.
  • Konsentra, a wholly-owned subsidiary of Ruter, which co-ordinates, plans and arranges passenger transport services. Every year, it arranges approximately 1.2 million trips commissioned by Ruter, Heels Sør-Øst as well as several municipalities in Akershus.
Ruter itself owns no buses, trams, boats or metros. Fleet operations are carried out by various operator companies that have a contract with Ruter. The metro and the tram are permanent contract partners, whereas bus and boat operators are awarded contracts after competitive tendering.

Is it possible to develop sustainable environment-friendly construction with the concept of smart city, green building and social and housing policy, ie building housing available for citizens with low incomes and, at the same time, housing that would meet the principles of sustainable pro-ecological economic development?
Yes, in my opinion, it is possible to combine technology and business. Taking into account the current technologies of ecological construction, technologies of renewable energy sources, etc., it is possible to combine such technologies as housing, socio-economic, ecological and smart city policies. Currently, this is possible technologically, while the key problem is mainly financing the development of this type of construction.
Unfortunately, as always with the need to develop new pro-ecological technologies, the key issue is the problem of finding sources of financing. In connection with the above, will sustainable sustainable housing development be developed to solve the problems of limited access to housing for people, low-income families, depends mainly on the financial capabilities of the state and local governments, state finances and awareness of the policy makers from the planned specific policy prosocial and residential as well as pro-ecological.

The determinants of renewable energies are -
1. The cost of renewables are high and many governments give subsidies to run their renewable energy production. So the cost of renewables must be lowered
2. Non-renewables are cheap and make lots of profit. But renewables are not profitable. But a high carbon emission tax is imposed on the non-renewables and more subsidies to renewables then the shift towards the renewables will accelerate
3. People still dont really know or care for the environmental problems that non-renewables cause. Public awarness should be raised in this regard.

The aim of the question is a discusion which could define the relationship between energy efficiency and aesthetics of architecture (and surrounding space). It is assumed that this dependence is a function of many factors; in my opinion that function could be related to the local community's activities . What activities? Perhaps the answer is a context of its development and dynamics of this development, sustainability of cities, its resistance to failures and disasters. What else?
Relevant answer
Answer
It is feasible to have energy-efficient buildings, while the aesthetics part is still desired. The principal factor in achieving this goal is that the implemented strategies for reducing energy demand should be a feature of the design. Thus, it is conditional on the architect's knowledge about energy efficiency approaches and and the ability to apply them in the final design. Of course, in big scale projects, close teamwork between energy counsellors and designers would be required.

📷 European International Conference on Transforming Urban Systems (EICTUS-2019)
🔷 26-28 Jun 2019 Strasbourg (France) 
✅ Introduction of the conference
With climate change, increasing world population, and new expected worldwide shares of fossil fuel energy resources, all cities will face to serious tensions in a very near future.
The EICTUS-2019 conference is proposed to bring together all the actors working on urban environment at international scale. The project aims to share experiences and create an international dynamic to find collective solutions to environmental and social problems that are arising progressively in many cities of the world.
✅ Major themes of the conference
📷 Sustainable cities
📷 Urban metabolism and sustainability
📷 Urban ecology and eco-services
📷 Urban land-use, development and planning
📷 Energy resources, sustainable urban energy productions and supplies
📷 Urban mobility, sustainable and innovative urban transport systems
📷 Urban pollutions (air, water, soil) and reduction strategies
📷 Urban risks, remediation and protection strategies
📷 Urban economy and cost-effectiveness strategies
📷 Other inter-disciplinary topics related to urban transition
The conference is proposed by the “Zone Atelier Environnementale Urbaine” (ZAEU) (https://zaeu-strasbourg.eu). ZAEU is an interdisciplinary research network, part of the Zones Atelier (ZA) of the Institute of Ecology and Environment (INEE) of the National Center for Scientific Research (CNRS), France. It is also art of the Long-Term Ecosystem Research in Europe (eLTER, http://www.lter-europe.net). Long-Term Ecosystem Research (LTER) is an essential component of world-wide efforts to better understand ecosystems. ZAEU is supported by the University of Strasbourg through the involvement of ~100 research scientists working in 13 research laboratories covering several fields and disciplines. It was built in connection with the Strasbourg city authorities, Strasbourg Eurometropole (EMS).
The main objective of ZAEU is to co-build common knowledge to face current and future environmental issues in a logical sustainable urban development. This co-understanding is based on a long-term observation of the processes and dynamics of the eco-social system. This involves understanding through the analysis of information collected, measured or simulated, the validation of these processes, the proposal of scenarios for the future, but also the exchange of information with local authorities to quickly applied results.
The accepted manuscripts will be published in conference proceedings. Other than the publication of conference proceedings, selected papers with extraordinary findings mainly about solutions to combat the environment problems at urban scale, will be published in form of a book for policy makers.

Do you agree with my opinion that in the context of the projected acceleration of the global warming process, humanity in order to avoid a global climate catastrophe should take as a priority in the 21st century a change in the classical economy on the new green economy to develop economies according to the concept of sustainable pro-ecological development, including replacing classic energy sources based on the combustion of minerals for renewable energy sources. In addition, in economic processes should be implemented as soon as possible and possibly the largest funds programs for reduction of greenhouse gases?
How can you slow down the global warming process in the 21st century?

Improvement of waste segregation carried out by citizens is an important issue that is an important element of sustainable pro-ecological development.
For some time, specific waste segregation and recycling techniques have been carried out in many developed and developing countries.
However, in many cases it does not work perfectly, and due to the growing problem of growing landfills of unsorted and non-biodegradable waste, these techniques should be improved.
On the other hand, in many cases also the waste segregation quality control system also does not work properly.
In the light of the above, encouraging discussion, I turn to you with the following question: Do you know any methods, tools on how to improve the quality control system for waste segregation, which is the segregation of citizens?
Please answer.
I invite you to the discussion.

Answer
I think that you meant in your last sentence (segregation by citizens) and not (segregation of citizens).
Well, we did an experiment in the 1980s in one floor of the faculty of science by placing bins "one for glass, one for plastics, one for metals, one for papers, and one for any waste".
I must admit that many students did abide by the rules of the game but unfortunately there were some "hooligans" who sneaked & caused mess in the bins spoiling our experiment.
My conclusion was that quality segregation of wastes by citizens requires education (to raise the level of thinking) & material rewards (to encourage individuals to participate in a good manner). After some time, the citizens will have the instilled or rooted habit of doing things the right way.

Sustainable pro-ecological industry development based on the concept of green economy consists in changing the business model that takes into account the following issues:
- reduction of production maximizing the quantity and activation of qualitative production,
- minimization of negative externalities, including generation of production waste polluting the environment,
- maximizing the recovery of secondary raw materials, development of recycling,
- implementation of saving and purification systems used for the production of water in a closed circuit,
- transition to renewable energy sources as a source of electricity for production processes,
- taxation of production plants, imposition on the production company of the costs necessary to carry out the reclamation of devastated environment as a secondary effect of the production process,
- improvement of employees motivation instruments to invent, design proecological technological improvements of the production process and development of ecological innovations.
In view of the above, I would like to ask you: What other determinants of sustainable pro-ecological industrial development can be mentioned in addition to the above?
Please, answer, comments. I invite you to the discussion.

I think future products need to be designed Completely with sustainability in mind. What I mean by this is understanding the secondary use or degration of all components And not using materials that can’t be recycled.

What pro-ecological activities can and should be implemented by The World Bank to inspire and effectively act on the issue of the sustainable pro-ecological development of the World?
According to the announcement of the President of the World Bank, from 2020 on, the expenditure on pro-ecological activities will be doubled.
Among other things, The World Bank will allocate USD 100 billion for investments in the public sector and additional USD billion for pro-ecological projects on various topics that are supposed to implement and inspire changes in the new green economy to ultimately reduce greenhouse gas emissions on Earth and to slow down increase in average temperature on the Earth's surface.
However, what specific pro-ecological investments should be implemented in order to achieve the intended results? How should those pro-ecological projects be run and in which topics, eg renewable energy sources, creation and implementation of ecological innovations, technologies and pro-ecological materials, etc.?
