The document discusses present and future urban problems and potential solutions. It identifies current problems such as air pollution, traffic issues, building density concerns, and ecological degradation. Solutions proposed include using natural gas vehicles, improving public transport, and increasing green spaces. Future problems mentioned are shortages of water, food, and energy if consumption patterns continue. New social structures may also emerge. Urban farming is suggested as a solution that could help address issues of resource scarcity by producing food locally.

1. URBAN FARMING
Present urban problems, future
urban problems

2. Urban problems of the present
• There are actual urban problems, which can be clearly identified and
„only” the solutions have to be found.
• These problems are the following:
– Local air pollution/smog
– Traffic problems
– Building problems
– Ecological degradation
– Urban heat balance problems (urban climate/urban heat island)
– Energy consumption problems
– Social problems
– Increasing rate of urbanisation
– Increasing difficulties of water supply
– Increasing difficulties of food supply
– Increasing vulnerability

3. • Solution: using CNG cars (existing viable technology)
Local air pollution/smog I.

4. • Solution: separation and isolation of industrial production
Local air pollution/smog II.

5. • Traffic congestions cannot be solved by ideal hubs.
Traffic problems I.

6. • Appropriate public transport can be the solution
Traffic problems II.

7. • Increasing demand for flats cause extreme densities.
Building problems I.

8. • Solution can be the appropriate „provision” of „Nature”.
Building problems II.

9. • Formal industrial areas, brownfield. Almost disappeared ecosystems.
Ecological degradation I.

10. • Solution can be letting the nature to do the job.
Ecological degradation II.

11. • Urban heat island.
Urban heat problems I.

12. • Solution can be the usage of natural, or natural-like surfaces.
Urban heat problems II.

13. • Solution can be the usage of natural, or natural-like surfaces.
Energy consumption problems I.

14. • Solution can be building pasive houses.
Energy consumption problems II.

15. • Solution can be building pasive houses.
Social problems I.

16. • Solution can be building pasive houses.
Social problems II.

17. • Solution can be building pasive houses.
Increasing rate of urbanisation I.

18. • Solution can be building pasive houses.
Increasing rate of urbanisation II.

19. • Solution can be building pasive houses.
Increasing difficulties of water supply I.

20. • Solution can be building pasive houses.
Increasing difficulties of water supply II.

21. • Solution can be building pasive houses.
Increasing difficulties of food supply I.

22. • Solution can be building pasive houses.
Increasing difficulties of food supply I.

23. • Solution can be building pasive houses.
Increasing vulnerability I.

24. • Solution can be building pasive houses.
Increasing vulnerability II.

25. Urban problems of the future I.
• There are problems, which currently do not exist. But it can be
prognostized that these problems will appear in a few decades.
• These problems are the following:
– Water supply
– Food supply
– Energy supply
– Appearance of new climate types, related to urban zones.
– Increased social problems, appearance of new social structures
– Appearance of huge urban regions
– Further increasing vulnerability

26. Urban problems of the future II.
• It is important to note, that the food problem is not an existing
phenomenon. Very simply: the urban starvation is not a current
problem excepting war zones.
• Nevertheless it is sure, that energy, water and food shortage will
appear in a few years.
• There are some settlement around the world, which vulnerability is
much greater than the others because of certain reasons.
• Cities of the USA: the mean water, food and energy consumption per
capita is many times greater than in case of any other country. This is
a feature of that society. Thus, the demands of an american city is
many times greater than any other city in an other country with the
similar number of inhabitants.
• Cities of India: Probably the densest cities with the lowest rate of
public utilities. The same problem („favela” problem) appears also on
other continent.
• Singapore: special political construction: urban state, island state.

27. Water supply I.
• It is

28. Water supply II.
• The problem is the density of the inhabitants and the height of
buildings. Collecting rainwater on a high level can solve problems.

29. Food supply I.
• The problem is the density of the inhabitants and the height of
buildings. Collecting rainwater on a high level can solve problems.

30. Food supply II.
• The problem is the density of the inhabitants and the height of
buildings. Collecting rainwater on a high level can solve problems.

31. New climate types.
• The problem is the density of the inhabitants and the height of
buildings. Collecting rainwater on a high level can solve problems.

32. Increased social problems
• Problem of homeless people and social inequalities is just one
segment. New environment can create new layers of society.

33. Huge urban regions
• Problem of homeless people and social inequalities is just one
segment. New environment can create new layers of society.

34. Increased vulnerability
• Problem of homeless people and social inequalities is just one
segment. New environment can create new layers of society.
