Brazil is the fifth-largest country on the planet, and about 90 percent of its territory is located within the tropics. This makes Brazil the largest tropical country and the most biodiverse on Earth. Especially since its process of state building in the 19th century, the image of the Brazilian nation has been intensely associated with the ideal of an exuberant and sumptuous nature, a land of fertility and abundance, like the Amazon rainforest. However, within this gigantic and diverse territory, there were many areas that differed from that nation ideal, like the semi-arid zone located mainly in the countryside of the region that from the middle of the 20th century became known as the Brazilian Northeast. Integrating this semi-arid zone - that is considered the largest tropical dry forest in South America - into the nation project headed by the Imperial Court in Rio de Janeiro was an important challenge in the construction of Brazil in the 19th century.
The climate issue was a decisive key to guiding this process. Although the famous drought in 1877 still frequently appears as the starting point for the importance of the political debate on the semi-arid climate in Brazil, the relations between climate and power in this territory were made earlier. Since the beginnings of the Brazilian Empire in the 1820s, for example, policies to deal with these climatic phenomena were decisive to articulate the power between local elites and the empire. These policies were transformed from occasional succors like groceries especially to water reservoirs after the 1840s. Handling the rainless climate would be crucial to uphold the imperial order in that semi-arid territory. The empire sought to have control not only over the people but also over the weather. However, this relationship between the empire and the “arid hinterland” took shape within the political and environmental Brazilian puzzle at that time, rather than a mere imposition from the court.

Water and Environmental Change in the US–Mexico Borderlands
Sterling Evans
Aridity, a significant characteristic of the U.S.–Mexico borderlands, has affected water use patterns for different groups of people in this region for thousands of years. From indigenous groups to European invaders and colonizers to 20th- and 21st-century farmers, ranchers, and policy-makers in Mexico and the United States, controlling the area’s scarce water resources has been a vital concern for survival and economic success. Given that an international border divides the region, national-era relations between the United States and Mexico often have been marked by water issues and the development of water projects and policies. And on both sides of the border these projects and policies have caused environmental changes that merit attention. Much of that history revolves around agricultural development with the need to ensure steady sources of water for irrigation. But industry and urban areas have also been enormous consumers of scarce water resources in the region, issues that are discussed here.
