  1. Living with life Prof.dr.ir. Taeke M. de Jong 2002-11-12 www.bk.tudelft.nl/urbanism/TEAM

  2. Problems • decline of biodiversity • bad human health

  3. Population and habitat of man Healthy species, ousting other species 80% unhealthy specimens

  4. The importance of diversity • for life • for human living

  5. Ecologicaltolerance

  6. Diversity as a hidden supposition • uniqueness of individual and context • average useless in ecology, management and design science • precondition of • communication • trade, economy • possibility of choice for future generations • quality of human living

  7. Quality = f(variation)

  8. Scale sensitive concepts • dispersion, rareness, responsibility • global • continental (blue list) • national (red list) • local • health • of species in the long term • of specimens in the short term

  9. State of dispersion as a prerequisite of diversity

  10. States of distribution on one level of scale

  11. Schale paradox

  12. Scale articulation

  13. Binary legend of man’s habitat

  14. Accords of distribution per level

  15. 1965 1995

  16. Randstad 1965-1995

  17. Principles of extension

  18. Ecology • Andrewartha (1961):Ecology is the scientific study of the distribution and abundance of organisms. • Krebs, C.J. (1972, 1992): Ecology is the scientific study of the the interactions that determine the distribution and abundance of organisms. • Pianka (1994): Ecology is the study of the relationships between organisms and the totality of the physical and biological factors affecting them or influenced by them. • Begon; Harper; Townsend (1996): Ecology is the scientific study of the the interactions that determine the distribution and abundance of organisms, populations and communities.

  19. Levels of scale (Pianka 1994)

  20. Types of ecology decreasing human centred approach

  21. Cybernetic variation

  22. Scale articulated ecological units

  23. Ecological elaboration • R=300m Ecological groups in ecotopes • R=30m Communities in biotopes • R=3m Symbiosis and competition • R=30cm Individual survival strategies

  24. The condition of measure The smaller the open area the less animals could find a habitat. But that is not the case for botanical biodiversity as far as their dispersion is not dependent on big animals.

  25. Possibilities for nature (H+N+S)

  26. Possibilities for recreation (H+N+S)

  27. Same surfacecentral or linear open space Same surface black and white (24 squares ) (Tummers-Zuurmond 1997)

  28. Dry connections

  29. Wet connections

  30. Interference wet and dry

  31. Scale-articulated dispersed central green area

  32. Vegetation biodiversity

  33. R=3km

  34. R=1km 180 species 200 species 330 species

  35. National rareness of 500 urban plant species in Zoetermeer

  36. Town ecology hypotheses

  37. Gobal and continental types

  38. R=1000km: Areas of vegetation

  39. R=100km: Counties of flora

  40. National typologies

  41. R=10km: Formations

  42. Comparing and evaluating

  43. Ecotopes, ecological groups

  44. Urban perspective

  45. The capacity of metropoles

  46. Death rates and medicine use

  47. Spatial human rights • Any human has a right on 300m2 residential area in a radius of 10km, work and services included. • Any human has a right on all necessary sources of living within a radius of 30km. These sources have to give access to products of 2000m2 agricultural land per person. This land should be accessible within a radius of 1000km concerning the risk of stagnating logistics. • Agriculture has to be located in areas with highest supply of water, minerals and sunlight. Towns and untilled natural areas have to be located in areas with less minerals. • Any human has a right on untilled natural ground uninhabited by man within a radius of x from her or his place of residence measuring at least a radius of x/3; x being {0.3, 1, 3 … 100 000 metre}. • Dutch cities belong to the most healthy in the world. So, any attention given to health in Dutch cities is distressing in a perspective of the hygienic condition of cities in the second and third world.
