This report summarizes the concepts and methods underlying the project and initial applications in Bolivia's Potosi region, one of six pilot project areas. An introductory chapter discusses the data needed to analyze the spatial dimensions of a region's economy, together with the main information sources in Bolivia and three field surveys-of urban centers, markets, and households-carried out to collect further information. A profile of the region's physical, demographic, and economic features shows that Potosi's development while slow, was closely associated with the growth of urban population. The next three chapters examine the principal features of the urban-rural system - settlements, the linkages among them and rural accessibility to urban-based functions. The region's existing spatial structure is analyzed and interpreted and spatial constraints to development are indicated. Specification of the general project strategy for use in Potosi is then detailed, and methods for designing packages of projects for each area of the region are discussed and illustrated. 收起
