Federal Decentralization and Adaptive Management of Water Resources: Reservoir Reallocation by the U.S. Army Corps of Engineers
Reservoir operations must respond to changing conditions, such as climate, water demand, regulations, and sedimentation. The U.S. Army Corps of Engineers (Corps) can reallocate reservoir storage to respond to such changes. We assembled and analyzed a database of reservoir reallocations implemented and proposed by the Corps.
Population Allocation at the Housing Unit Level: Estimates around Underground Natural Gas Storage Wells in PA, OH, NY, WV, MI, and CA
Spatially accurate population data are critical for determining health impacts from many known risk factors. However, the utility of the increasing spatial resolution of disease mapping and environmental exposures is limited by the lack of receptor population data at similar sub-census block spatial scales.
As electricity companies in low- and middle-income countries move deeper into rural regions, the cost of new connections generally increases while the electricity demanded by these new customers remains lower than urban and peri-urban customers. This is a challenging dynamic for utilities looking to sustain their financial health as well as for governments tasked with engineering viable strategies for achieving universal electrification.
Getting to Yes: Internal Preparations—State Carbon Trading Checklist for a Meeting with the Governor
Public attention focuses on a policy once a governor makes a formal announcement and sets the debate in motion. However, much of the work happens before that moment, in conversations among state officials and their staff, and with key stakeholders. This memo is intended to support the work of “getting to yes” on a policy—in this case, a declining cap (and trade) program to reduce carbon dioxide emissions—once internal leadership has decided it is worth exploration.
Over the last decade, efforts to use compensatory mitigation to manage and ameliorate the impacts of development on biodiversity and ecosystems around the world have accelerated. Mitigation mechanisms provide a structured way to advance economic development and infrastructure while also achieving environmental goals. In order to operationalize mitigation programs, practitioners need a methodology for calculating or quantifying impacts and offsets (debits and credits). The methods currently employed in the U.S. and abroad are extremely varied. Surprisingly, the literature on best practices or standards for developing science-based approaches to the quantification of impacts and offsets is sparse and there is also no single broadly accepted best practice guidance.
Are There Benefits to Integrating Corporate Health and Environmental Strategies? An Exploration of the Food/Agriculture and Textile Sectors
Businesses impact environmental determinants of health and can play an important role in creating integrated approaches for promoting a healthy environment. This report describes the ways in which the food/agriculture and textile sectors affect environmental conditions that are associated with health risks and assesses how companies are tracking and addressing these interconnected issues.
On February 21, 2019, Duke University’s Energy Access Project and Oxfam cohosted a meeting of approximately 60 energy practitioners and researchers to discuss the role of electricity access in spurring productive use. A motivation for this convening was a paper, produced by Oxfam, which had been confounded by the mixed findings on the impact of electrification on productive use.
Managing Rivers Under Changing Environmental and Societal Boundary Conditions, Part 1: National Trends and U.S. Army Corps of Engineers Reservoirs
Most major rivers in the United States are managed by a system of reservoirs; many of which were built more than a half century ago. These reservoirs were designed based on environmental, societal, and regulatory assumptions at the time of construction. Since then, we have learned that climate is not stationary, population growth is being decoupled from energy needs and water demand, and new regulations (such as the Clean Water Act and Endangered Species Act) affect how river systems are managed.
Managing Rivers Under Changing Environmental and Societal Boundary Conditions, Part 2: Expected Compared With Experienced Conditions at U.S. Army Corps of Engineers Reservoirs
Reservoirs are critical infrastructure typically built to function as designed for 50 to 100 years. The majority of U.S. Army Corps of Engineers reservoirs are more than 50 years old. The environmental, societal, and regulatory conditions surrounding the reservoir, that is, the reservoir's expected conditions, shaped its design. Many of these expectations assumed a future similar to the past. However, recent decades have experienced warming climates, cyclical changes in precipitation, the introduction of new regulations, and populations concentrating in urban environments.
