Infrastructure Disturbances

Urbanization, Transportation & Industry

MIT Environmental Strategies for Cities
This web site is for cities to initiate environmental management programs. It is targeted toward urban policy analysts, decision-makers, planners, and managers, as well as to the environmental community at large and international agencies.

Dams & Hydrology

Centre for Ecology and Hydrology
CEH’s Water Programme provides scientific insights to the processes that determine water flows and water quality, in order to assist the sustainable management of catchments and their water resources.

Conservation Science Institute
Dams are used to block and harness rivers for a variety of purposes, including hydropower, irrigation, navigation, flood control, and water storage. There are approximately 75,000 dams greater than 6 feet along the waterways of the United States, and, according to the U.S. Army Corps of Engineers, there are at least tens of thousands of smaller dams plugging rivers across the country.

Dam Repair or Removal: A Decision-Making Guide
Dams — structures designed to hold back the natural flow of a river — profoundly affect river ecosystems and people’s interactions with the river. When a dam is built, the river’s water rises behind the dam, flooding the land behind the dam that is a lower elevation than the crest of the dam. Impoundment is a general term for the body of water, regardless of size, formed by damming a river.

International Rivers Network
Millions of people worldwide are facing serious threats to their livelihoods and cultures due to the construction of large dams. Intended to boost development, these projects have led instead to further impoverishment, degraded environments and human rights violations.

Rethinking Large Dams
Large dams have been built on over seventy percent of rivers around the world, the majority of which are located in three countries: the United States, China, and India. But opposition to these industrial development projects is increasing worldwide, due to social and ecological impacts. On this program, we take a look at movements to end the construction of large dams.

Fire & Weather

Aldo Leopold Wilderness Research Institute
The fire research program at the Leopold Institute is presently initiating and supporting research to help land managers better understand wildland fire issues, enabling them to develop and implement necessary fire management plans that may include the use of natural ignitions or prescribed fires.

Florida Department of Agriculture & Consumer Services
The mission of the Forest Protection Bureau to provide a level of fire management that reduces threats to life and property, forests, and other related at-risk wildland resources, while promoting natural resource management through the use of prescribed fire.

In North America, wildfires in boreal forests have doubled in area over the last 50 years. Even so, Larry Hinzman at the University of Alaska in Fairbanks knows you sometimes have to set fires to learn about them. He co-authored a study this year on one of the largest prescribed wildfires ever, a burn in Alaska covering almost 10 square kilometers or about four square miles. The study – called FROSTFIRE – brought together more than 50 research groups.

Intute Online Resource on Natural Hazards
These pages draw together resources about a range of natural hazards. These resources include satellite images, maps, articles, links to data, information on current and historical events, links to sources focusing on the measurement/classification of events, combined with links from the Intute Internet resource catalogue. Together these provide a growing resource about natural hazards around the globe.

Mt. St. Helens Revisited
Scientists have learned that where any structure at all survived around Mount St. Helens, life came back more quickly. Now what were forest landscapes are largely meadowlands with grasses, insects, birds, gophers, mice—and even some shrubs and trees. This disproves traditional models that say recolonization always occurs in a strict sequence—from mosses to lichens to herbs to shrubs and, finally, to trees.

National Wildfire Coordinating Group
The purpose of NWCG is to coordinate programs of the participating wildfire management agencies so as to avoid wasteful duplication and to provide a means of constructively working together.  Its goal is to provide more effective execution of each agency’s fire management program.

US Forest Service
The Fire and Aviation Management part of the USDA Forest Service is a diverse group of people working to advance technologies in fire management and suppression, maintain and improve the extremely efficient mobilization and tracking systems in place, and reach out in support of our Federal, State, and International fire partners.
