Population movements modify the environment, land-use, and shape the landscape through urbanization. Furthermore, migration has become one of the most relevant determinants of global human health and social development. The objective of this paper is to provide a framework to understand the economic and natural factors responsible for migration and population agglomerations and their environmental consequences. In this regard, we develop an economic model in continuous time and space adapting Hotelling’s migration law to make individuals react to possible improvements of their welfare. First we show that there is solution to this spatial-dynamic problem. Then, we illustrate the properties of the economy and the associated population dynamics through numerical simulations.

Practicability of viewing economy not as a mechanism but as an organism is grounded. The concept of "genetic economics" that is considered in time and space is defined. The orders of economic constancy are recommended. "Genetic economics" axiomatic statements are formularized.

I begin my exploration of ‘Ali Mubarak (1823/4–1893) and the discourses on modernization ‘performed’ in his only attempt at fiction, ‘Alam al-Din (The Sign of Religion, 1882), with a quote from Guy Davenport because it elegantly sums up a key theoretical principle underpinning any discussion of cultural transformation and, more particularly, of modernization. Locating ‘Ali Mubarak and his only fictional work at the juncture of the transformation from the ‘traditional’ to the ‘modern’ in the recent history of Arab culture and of Arabic narrative, I find Davenport's pronouncement tantalizingly appropriate. He not only places the stakes of history and geography in one another, but simultaneously opens up the imagination to the combined forces of time and space that stand behind these two distinct yet related disciplines.

Care’ is a shifting, plural word when used in the context of discussions of health. It suggests attention and compassion when articulated as a verb, but has overtures of regulation and control when used as a noun – to be ‘in care’ is usually not unproblematic. Two chapters in this section – those by Sarah Atkinson and Lucy Burke – speak specifically to the complexities of this idea. As Atkinson makes clear in her chapter, care invokes questions of resource just as much as it outlines interpersonal relationships; it presents what she terms ‘dilemmas, paradoxes and challenges’ when conceived of as a totality and, especially in global contexts, suggests entangled modes of time and space.
