Ecology, Planning, and River Management in the United States: Some Historical Reflections

Abstract

River ecologists are also river-basin planners. However, their role in planning has developed slowly over the decades since the beginning of the 20th century. Three major factors explain this phenomenon. First, ecologists focused on plant and animal communities rather than on broader policy issues related to land settlement and water development. Second, the federal government, and most state and local governments as well, used mainly economic criteria to justify projects. Intangible benefits, including the value of species or an aesthetically pleasing landscape, drew relatively little attention. Third, the public generally favored development, especially during the Great Depression of the 1930s. Only after World War II did the public's position shift in favor of more preservation, as ecologists developed the concept of the ecosystem, large dam projects forced basin inhabitants from their homes, and chemical and nuclear pollutants threatened the environment. Also, urbanization increased support for the preservation of recreation sites and of streams undisturbed by human intervention. Meanwhile, partly through important advances in geomorphology and hydrology, ecologists acquired new tools to understand the land-water relationship within river basins. Neverthless, benefit-cost analysis continued to dominate federal waterresources planning, and organizational culture and competing or overlapping bureaucracies hampered rational water resources administration. Environmental groups and physical, natural, and even social scientists began to promote alternative ways to develop rivers. Today, the ideas of integrated water resources management, sustainable development, and comprehensive river-basin management dominate much of the thinking about the future course of river planning in the United States. Any future planning must include ecologists who can help their planning colleagues choose from among rational choices that balance ecological and human demands, provide advice when planning guidance is drafted, assist engineers in designing projects that lead to ecologically responsible solutions, and help monitor results.

Archaic and contemporary topographic diversification of Upper Mississippi River forests

“…Ecology in general, and restoration ecology in particular, requires the union of ecological and social values (Reuss ; Statzner et al ). Wohl et al () highlighted the challenges this union presents for river restoration, “Despite the importance of an ecosystem context, river restoration projects are as much a social undertaking as an ecological one.” Nowhere is this union better exemplified than with the world's major rivers and with the UMRS in particular.…”

Analysing the Role of Visions, Agency, and Niches in Historical Transitions in Watershed Management in the Lower Mississippi River

“…This post-hurricane development was based on the recognition that wetland ecosystems, whether forested or not, are critical buffers for mitigating the impacts of hurricanes in coastal areas [80]. Although US Congress gave the Corps a specific ecosystem restoration mission in the 1990s, ecosystem restoration further complicates the problems water resource planners face [80,82]. A panel on adaptive management for resource stewardship served as a committee to assess the Corp's methods of analysis and peer review for water resources project planning [83].…”

Environmental Realism

“…Marsh (1860) emphasized that humans must manage nature both for the good of nature and society and in such a way that retains human dominance. This philosophical approach continued well into the twentieth century, as early studies of ecology recognized interconnectedness of biological and physical systems, but excluded humans from these systems (Reuss 2005). Hays (1959) argued that while the conservation movement has a reputation as a "defender of spiritual values and national character," conservation "above all, was a scientific movement, and its role in history arises from the implications of science and technology in modern society."…”
