Unit
1: What Are Environmental Hazards?
Answers to Activities |
| Activity 1.1 My Very Own
Disaster |
Students should relate their experience or that of a close relative or
acquaintance clearly and interestingly and should finish the activity having
gained an awareness of the following main points:
hazards are phenomena that affect all of us, frequently in physical or
metaphysical areas close to home;
different people may experience the same or similar hazard event in different
ways;
what are hazards in one region may not be perceived as hazards elsewhere
(see Supporting Material
1.1 for a personal account of a snow storm in Texas that makes
this point well).
| Activity 1.2 Delineating
the Hazards of Places |
The results of this activity depend on the countries chosen, the amount
of information students are able to find, and their individual creativity
and diligence. In evaluating students’ reports, assess the following aspects
of their presentation:
clarity of presentation (tables and charts constructed, visuals, speech)
diversity of information included
number of Web sites used
overall informational content of the hazard profile
inclusion of appropriate contextual information regarding the ability to
respond to hazards
Below is an example of a hazardscape of one country, Indonesia.
Indonesian Hazardscape
Located in Southeast Asia, Indonesia is an archipelago of over 13,000
islands, 6,000 of which are inhabited. Indonesia’s location near the Equator
places it along major sea lanes between the Indian and Pacific Oceans.
The total land area is about 1.8 million sq. kilometers with over 54,000
km of coastline. The population is estimated to be about 203.5 million
with a growth rate of 1.5%.
Current environmental issues include deforestation, water pollution
from industrial wastes, sewage, and air pollution in urban areas. Natural
hazards include floods, droughts, tsunamis, earthquakes, landslides, and
volcanoes. Human health hazards include exposure to hepatitis B, Japanese
encephalitis, typhoid, rabies, cholera, and malaria in rural areas.
Indonesia is party to numerous international agreements concerning biodiversity,
climate change, endangered species, hazardous wastes, the law of the sea,
nuclear test bans, ozone layer protection, ship pollution, tropical timber,
and wetlands. Japan supplies most of Indonesia’s disaster and economic
aid.
Disaster statistics and background information on the country can be
obtained by conducting a Web search on Indonesia (e.g., at the following
site: http://www.polrisk.com/
where you select Indonesia and go through the fact sheet, the geography
section and so on). Then check any of the hazard-related Web sites on specific
information. For very good information on Indonesian volcanoes, for instance,
go to the Volcano World web site at the University of North Dakota (http://volcano.und.nodak.edu),
ready with narratives, updated disaster statistics, satellite imagery,
photographs, and so on. From this site comes the table shown below. The
amount of information for some countries is enormous!

Below are two examples of charting disaster statistics for a different
country, Ecuador.
| Activity 1.3 Five Myths About
Hazards |
The following myths or misconceptions are described in greater detail in
Jones (1993):
-
tendency to focus on conspicuous, dramatic, high-energy events of questionable
regional or global significance in terms of losses;
-
tendency to focus on large-scale loss events ("disasters"), denying attention
to smaller, cumulative events;
-
tendency to concentrate on death toll as the easiest obtainable, but maybe
least telling impact statistic;
-
tendency to emphasize the powerlessness of humans vis à vis "natural"
forces;
-
tendency to highlight the value of techno-centric solutions to hazard problems.
Students should present a clear analysis of the extent to which the news
articles that they have chosen reflect the myths that Jones describes;
they may or may not find all five represented in the paper. For those myths
they can identify, students should provide examples. This will give you
an opportunity to see whether they adequately prepared for class, understood
the readings, and can apply the knowledge of these myths to a text on hazards.
| Activity 1.4 Differences
in Hazard Perception |
The results of students’ surveys cannot be predicted, as they will depend
on the types of environmental risks present, the kinds of neighborhoods
surveyed, the gender and ethnic mix, and the survey questions and hypotheses
students investigated. Use the list below as a guide for assessing students’
work:
-
Did students prepare a set of survey questions and research hypotheses,
hand them in on time, and make changes to them as suggested before conducting
the survey?
-
How many people did the students survey? Was there a good mix of people?
-
Did students write a clear, concise, and reasonably well explained report?
-
Did students make an effort to incorporate background information about
the surveyed neighborhoods in trying to explain their findings?
-
Did students make use of the readings suggested for this activity, e.g.,
by referring to claims, research findings, hypotheses, etc. in those studies?
-
Did students show a critical awareness of the potential and limits of the
survey?
-
Did students include graphics, tables, and maps in their report?
