Many of these are caused by diseases, algal blooms, insects, animals, species extinction, deforestation, land degradation, and comet and asteroid strikes that have important implications for humans. Perspectives from both natural and social sciences provide an in-depth understanding of potential impacts.

It seems that you're in Germany. We have a dedicated site for Germany. This book examines the aspects of prevention, mitigation, and management of environmental hazards and disasters from an international perspective. In light of the recent debate on climate change and the possible effects of such a change upon increasing frequency and magnitude of extreme environmental events, this publication overviews various policy and response discourse. Several case studies, from various countries and world regions, depicting recent experience in mitigation policy and program development and implementation and establishing interlinks between vulnerability and mitigation are presented to provide further insights. This book is primarily intended for academics, policy makers, professionals, and practitioners in hazards reduction activities who look for a better understanding of the complex and dynamic aspects of nature and society. This topic is a well established issue among most sectors of our society since the costs, both human and socioeconomic, of extreme environmental events have been rising astronomically, and significant vulnerabilities exist throughout the world.

Losses due to natural hazards e. One response to hazard-related losses is migration, with this paper offering a review of research examining the association between migration and environmental hazards. Using examples from both developed and developing regional contexts, the overview demonstrates that the association between migration and environmental hazards varies by setting, hazard types, and household characteristics. In many cases, however, results demonstrate that environmental factors play a role in shaping migration decisions, particularly among those most vulnerable. Research also suggests that risk perception acts as a mediating factor. Classic migration theory is reviewed to offer a foundation for examination of these associations.

causes of human vulnerability to hazards, and the role of environmental conditions in exacerbating and effects of natural hazards and man-made disasters”2.
There are a range of environmental health hazards that affect our wellbeing. Hazards can be grouped together to improve understanding and action planning. The actions that you need to carry out to protect the health of your community depend on knowing how these hazards can affect us all. In this study session, you will learn about the types and categories of environmental health hazards, the routes of exposure and the ways of preventing and controlling these hazards. In Study Session 1, you learned that environmental health addresses the assessment and control of environmental factors that can potentially affect health.
Geography, with its focus on human-environment interactions, provides key analytical tools for understanding the complex causes and uneven impacts of hazards around the world. We will explore the geophysical nature and social dimensions of disasters caused by floods, droughts, earthquakes, volcanoes, tsunamis, tornadoes, hurricanes, and wildfires. For each of these hazard types, we apply theoretical concepts from major hazards research paradigms, including quantifying the human and economic impacts of disaster; assessing, managing, and mitigating risk; and reducing the impacts of disaster, not only through engineering works but also by reducing social vulnerability and enhancing adaptive capacity. Looking into the future, we will discuss how global-scale processes, such as climate change and globalization, might affect the frequency, intensity, and geographical distribution of environmental hazards in the decades to come.

An environmental hazard is a substance, state or event which has the potential to threaten the surrounding natural environment or adversely affect people's health , including pollution and natural disasters such as storms and earthquakes. It can include any single or combination of toxic chemical, biological, or physical agents in the environment, resulting from human activities or natural processes, that may impact the health of exposed subjects, including pollutants such as heavy metals, pesticides, biological contaminants, toxic waste, industrial and home chemicals. Human-made hazards while not immediately health-threatening may turn out detrimental to a human's well-being eventually, because deterioration in the environment can produce secondary, unwanted negative effects on the human ecosphere. The effects of water pollution may not be immediately visible because of a sewage system that helps drain off toxic substances. If those substances turn out to be persistent e. In that respect, a considerable number of environmental hazards listed below are man-made anthropogenic hazards.
SUMMARY This chapter defines natural hazards and their relationship to natural resources they are negative resources , to environment they are an aspect of environmental problems , and to development they are a constraint to development and can be aggravated by it. The chapter demonstrates that the means of reducing the impact of natural hazards is now available. The factors that influence susceptibility to vulnerability reduction-the nature of the hazard, the nature of the study area, and institutional factors-are discussed. The core of the chapter explains how to incorporate natural hazard management into the process of integrated development planning, describing the process used by the OAS-Study Design, Diagnosis, Action Proposals, Implementation-and the hazard management activities associated with each phase. The chapter goes on to show how the impact of natural hazards on selected economic sectors can be reduced using energy, tourism, and agriculture as examples.
