Converging on Solutions to Plan Sustainable Cities

solutions converging to zero

The aim of this note is to show that the following difference equation xn+1 = α + xn−k ∑k−1 i=0 cixn−i , n = 0, 1, . . . , where k ∈ N, ci ≥ 0, i = 0, . . . , k− 1, ∑k−1 i=0 ci = 1, and α < −1, has solutions which monotonically converge to zero. This result shows the existence of such solutions which was not shown in the recently accepted paper: A. E. Hamza, On the recursive sequence xn+1 = α +...

Sustainable Trees for Sustainable Cities

The idea of sustainable cities is linked to an older concept of sustainable plant communities. The theoretical basis for both is a closed system where everything is continuously recycled. Natural resources are renewed rather than depleted. In undisturbed natural areas a kind of sustainability is achieved through the natural cycles of the biosphere. However, this kind of sustainability for trees...

A Storytelling Planning Process to Transform Environmental Values into Sustainable Cities and Sustainable Behaviours

The concept of sustainability inspired most urban development plans after Rio 1992, although many such plans have not been too successful. An important reason for this is the disjuncture of science from culture and traditional knowledge and planners’ inability to conceptualize the environmental values of societies.This research aims to explore storytelling’s ability to aid in identifying of env...
