context_page_description: The environmental history of Latin America has become the focus of a number of scholars, starting in the later years of the twentieth century. But historians earlier than that recognized that the environment played a major role in the region's history. Environmental history more generally has developed as a specialized, yet broad and diverse field. According to one assessment of the field, scholars have mainly been concerned with "three categories of research: colonialism, capitalism, and conservation" and the analysis focuses on narratives of environmental decline. There are several currents within the field. One examines humans within particular ecosystems; another concerns humans’ cultural relationship with nature; and environmental politics and policy. General topics that scholars examine are forestry and deforestation; rural landscapes, especially agro-export industries and ranching; conservation of the environment through protected zones, such as parks and preserves; water issues including irrigation, drought, flooding and its control through dams, urban water supply, use, and waste water. The field often classifies research by geographically, temporally, and thematically.
context_section_description: Aqueducts were constructed to supply urban centers with drinking water.  Before the Spanish conquest in 1521, the Aztecs had constructed an aqueduct from a spring at Chapultepec (“hill of the grasshopper”) to Tenochitlan to provide freshwater to the urban population of nearly 100,000.  It had dual pipes so that maintenance of the aqueduct would not cut off the Aztec capital’s water supply. The aqueduct was constructed using wood, carved stone, and compacted soil, with portions made of hollowed logs, allowing canoes to travel underneath. During the Spanish conquest of the Aztec empire, Hernán Cortés realized the importance of the Chapultepec aqueduct to the Aztecs and cut the water supply to Tenochtitlan. In the colonial period, the Chapultepec aqueduct continued to function, with 904 arches and an open air path for drinking water.   In the late nineteenth century, there were major public hydraulic works undertaken to create a network of piped fresh water to Mexico City, since scientific ideas had identified water as a vector for disease.  Shortly after the Spanish conquest, the aqueduct of Acámbaro was constructed in Guanajuato.   The Zacatecas aqueduct  was constructed to supply drinking water to the major mining center.  A Roman-style aqueduct of Queretaro was completed in 1738 to provide drinking water to the provincial capital of Querétaro. It was privately funded by Don Juan Antonio de Urrutia y Arana, Marques de la Villa del Villar del Aguila. It functioned into the twentieth century to supply drinking water to the city and continues to supply water to the city’s water fountains. Other colonial-era aqueducts are the  Morelia aqueduct; the Saucillo aqueduct in Huichapan, Hidalgo state; the Chihuahua aqueduct; the Guadalupe aqueduct in the Villa de Guadalupe, in northern Mexico City; another constructed near the capital was the Santa Fe aqueduct; and also the Tepozotlan aqueduct. Although many aqueducts were built in the colonial era, there have been no studies of their impact on their local watersheds.
