Over the past 300 years, settlement patterns, geography, and climate have greatly affected the ecology of the south Texas landscape. Drawing on a variety of interests and perspectives, the contributors to On the Border probe these evolving relationships in and around San Antonio, the country's ninth-largest city.Spanish, Mexican, and American settlers required open expanses of land for agriculture and ranching, displacing indigenous inhabitants. The high poverty traditionally felt by many residents, combined with San Antonio's environment, has contributed to the development of the city's unusually complex public health dilemmas. The national drive to preserve historic landmarks and landscapes has been complicated by the blight of homogenous urban sprawl. But no issue has been more contentious than that of water, particularly in a city entirely dependent on a single aquifer in a region of little rain. Managing these environmental concerns is the chief problem facing the city in the new century.

Garbage, wastewater, hazardous waste: these are the lenses through which Melosi views nineteenth- and twentieth-century America. In broad overviews and specific case studies, Melosi treats the relationship between industrial expansion and urban growth from an ecological perspective.

Human settlement of the Lower Mississippi River Valley—especially in New Orleans, the region\u2019s largest metropolis—has produced profound and dramatic environmental change. From prehistoric midden building to late-twentieth century industrial pollution, Transforming New Orleans and Its Environs traces through history the impact of human activity upon the environment of this fascinating and unpredictable region.In eleven essays, scholars across disciplines––including anthropology, architecture, history, natural history, and geography––chronicle how societies have worked to transform untamed wetlands and volatile floodplains into a present-day sprawling urban center and industrial complex, and how they have responded to the environmental changes brought about by the disruption of the natural setting. This new text follows the trials of native and colonial settlers as they struggled to shape the environment to fit the needs of urbanization. It demonstrates how the Mississippi River, while providing great avenues for commerce, transportation, and colonization also presented the region\u2019s greatest threat to urban centers, and details how engineers set about taming the mighty river. Also featured is an analysis of the impact of modern New Orleans upon the surrounding rural parishes and the effect urban pollution has had on the city\u2019s water supply and aquatic life.
