Overview: This essay proposes a novel compactness standard “for courts to identify at least the worst cases of gerrymandering and to provide a remedy.” This standard is based on the perception of gerrymandering as aggressive voter exchange, an exchange that distorts the shapes of election districts and renders them non-compact by expelling voters living close by and exchanging them for voters living further away.

Overview: This paper discusses strategies for the development of water resources, emphasizing the delivery of reliable water supplies, for both domestic and production purposes, to every village and to every farmer. This necessitates a shift of emphasis from the construction of large storage reservoirs to the construction, operation, and maintenance of water distribution systems capable of reaching the largest number of farms, and a shift from projects that benefit the few, to projects that benefit the many. Water distribution in this context takes on three interrelated meanings: a geographical meaning, a technical meaning, and an economic meaning.

Overview: When the commercial or government forms of credit are inaccessible, poor people are found to establish credit mechanisms amount themselves. Throughout the developing world, people share the risk of lending money to each other by forming small credit societies where periodic savings of all members go to one of the members on a rotating basis. Our interest in studying the social and economic organization of poor urban communities, particularly with respect to mutual aid in housing finance, has led us into a detailed investigation of this phenomenon.

Overview: The city is not an undifferentiated terrain and travel does not occur along straight-line paths at constant velocities. Variations in travel velocities at different locations bend the minimum time paths away from regions of high congestion. This paper discusses a transformation of the urban plane into a time surface on which distance corresponds to travel time, and describes the construction of minimum paths and isochrones for various velocity fields.
