Invasive species can cause substantial reductions in a region’s ecological, industrial, and human welfare, and often require significant control expenditures. The Emerald Ash Borer, for example, established itself in the United States in the early 1990s and has caused the death of hundreds of millions of ash trees and is estimated to cause billions of […]
Invasive species impose severe ecological and economic changes on their new ecosystems—the United States alone suffers billions of dollars’ worth of damage every year due to the introduction and proliferation of non-native species. Bioinvasions often are viewed as a problem to be tackled by a top-down central decisionmaker seeking to control invaders across large swaths […]
In 1990, the Acid Rain Program introduced market-based environmental policy on the largest scale ever attempted. The program capped the total level of acid rain–causing sulfur dioxide emissions from the US electricity sector and allowed utilities to trade under that fixed cap—a so-called cap-and-trade system. Ironically, though much of the original motivation for that program […]
What Did the 2010 Deepwater Horizon Oil Spill and Offshore Drilling Moratorium Mean for the Workforce?
On April 20, 2010, the Transocean Deepwater Horizon suffered a catastrophic blowout while drilling in a BP lease in the Gulf of Mexico’s Macondo Prospect. This accident resulted in the largest oil spill in US history and an unprecedented spill response effort. Due to the ongoing spill and concerns about the safety of offshore oil […]
An increasing number of conservation projects designed to address ecological management, protection, and restoration are being judged based on the investment returns they are able to produce. The costs, benefits, and risks of these projects can all be assessed using conservation return on investment (ROI) analysis, a method to help conservancies prioritize possible programs based […]
Sea-level rise will increasingly threaten coastal communities. Responses to the issue have generally been grouped into three broad categories: protect, accommodate, and retreat. All three of these strategies will be needed and deployed to varying degrees around the United States. Highly developed areas—think New York City—will require some structural protection. Certain facilities that need to […]
In the twentieth century, flooding caused more deaths and property damage in the United States than any other natural disaster. Most climate models predict that flooding will worsen in the future, a prospect that is leading a growing number of communities to explore the use of natural areas as protection against extreme events. These areas […]
When is ingenuity likely to help solve ecological problems? Is humanity’s ability to innovate its way around environmental problems relevant to how we think about conservation? I tackle these questions and contemplate the limits to ingenuity in a piece for the latest issue of Resources. Read the full article here.
Each year, the US government spends billions of dollars to build, maintain, and manage water infrastructure and water resources. Federal principles directing how the US Army Corps of Engineers and other agencies assess, plan, and invest in flood control, water storage, navigation infrastructure, and other water resources date back to 1983. The realities of science, […]
Americans love the coast. We live there. We vacation there. Coastal areas generate substantial economic activity. But building on the coast is risky—storms and sea level rise threaten coastal development. Is there a model of development that allows us to enjoy all the ocean has to offer and yet reduces the risks from these hazards? […]
