Expected impact of various planning strategies on (a) economic growth, and (b) population growth of development areas In addition to the expected effect of the aforementioned measures on the economic development of peripheral desert regions, some positive changes in the population growth of these areas can also be expected.

This general trend may have two inflection points (#1 and #3) which correspond with the distances practicable for daily and periodic commuting, respectively. • The level of urbanization (population size and density) of particular geographic areas generally has a positive impact on the area's attractiveness to potential migrants. New immigrants, in particular, tend to settle in densely populated central regions rather than in relatively undeveloped peripheral areas (Fischer 1976; De Jong & Fawcett 1981; Moore & Rosenberg 1995).

4 Urban Settlements in Israel: Inequalities of Population Growth Statistical data on the population growth of urban localities in Israel (Local Authorities in Israel: Physical Data 1994-96; Statistical Abstract of Israel 1993-96) indicate that, for the period of 1992-93, this growth varied considerably across settlements of different sizes. In particular, the highest rates of annual population increase were exhibited by urban localities of 10,000-25,000 residents (Fig. 1). To understand the nature of this phenomenon and its implications for planning, a case study was undertaken with several major objectives: 1) to explain why localities of the above size tend to grow faster than other urban settlements; 2) to determine the main factors and prerequisites which contribute to the population growth patterns of the country's urban settlements in general, and 3) to Boris A.
