This article presents some of the innovative practitioner experiences with environmental impact assessment (EIA) follow-up discussed at a workshop during the recent IAIA’01 conference in Colombia. Key issues raised included how EIA follow-up is initiated and who is responsible. Examples driven by proponents, regulators and the community are presented. Key points are that a focus on environmenta...

Brazil's Tucuruí Dam provides valuable lessons for improving decision-making on major public works in Amazonia and elsewhere. Together with social impacts, which were reviewed in a companion paper, the project's environmental costs are substantial. Monetary costs include costs of construction and maintenance and opportunity costs of natural resources (such as timber) and of the money invested b...

In the United States, stream restoration is an increasing part of environmental and land management programs, particularly under the auspices of compensatory mitigation regulations. Markets and regulations surrounding stream mitigation are beginning to mirror those of the well-established wetland mitigation industry. Recent studies have shown that wetland mitigation programs commonly shift wetl...

Todays world relies heavily on spatial data to manage the natural and built environments. Monitoring and controlling the impact of human activities on the environment and the impact of natural environmental changes (including natural hazards) on the built environment is a major policy driver for many jurisdictions. The mitigation of natural hazards including tsunamis, earthquakes and landslides...

Climate change is one of today's most pressing global issues. Policies to guide mitigation and adaptation are needed to avoid the devastating impacts of climate change. The health sector is a significant contributor to greenhouse gas emissions in developed countries, and its climate impact in low-income countries is growing steadily. This paper reviews and discusses the literature regarding hea...

this paper presents future trends of urban wastes and their impacts on the environment of african cities using plausible mitigation scenarios. to accomplish this, an integrated dynamic model for urban waste flows was developed, tested, calibrated and validated. its parameter sensitivity was analyzed. using population projection up to 2052 with different levels of technological implementation, p...

this paper utilises the modified folchi method to assess the environmental impact of coal washing plant, alborz sharghi, north-east iran. in this study, the number of factors designed in the method was slightly modified by focusing on the environmental impact of coal washing operations. in addition, few other factors were designed and added to the previous factors. then, twenty-one values of en...

Greenhouse gas (GHG) emissions can be reduced or atmospheric GHGs sequestered to help reduce the future extent of climate change. Options to do this through agriculture have received increasing attention during the last decade. Some see agriculture as a potential low-cost provider of emission reductions in the near future with additional environmental and income distributional cobenefits. Other...
