Environmental Monitoring
and Sustainable Development:
Adequate
environmental monitoring in achieving sustainable development
Fukuya Iino
There are many types of environmental monitoring activities such as
permanent monitoring stations, real time monitoring, early warning, and
research-oriented temporary settings. Although the specifics of and environmental
monitoring design are dependent on a given projectfs focus, all adequate
environmental monitoring designs need to consider the following key elements:
1. clear end-use policy objectives;
2. known statistical power to detect the environmental monitoring target and
consequent risks set;
3. good quality assurance scheme and quality control indicators;
4. cost estimates reflecting multiple environmental monitoring technology
choices;
5. review processes to flexibly adjust the monitoring plan using collected
data as feedback and;
6. some freedom to allow scientists to explore unknown risks.
Providing policy makers with more, clearly presented, scientific
information, is one way the scientific community can better achieve their
objectives in the decision making process. In order to do so, not only do
decision makers need to increase their scientific literacy but also
scientists must conduct more user-oriented assessments prior to disseminating
their research and environmental monitoring results. In this sense, adequate
environmental monitoring needs to have clear end-use policy objectives.
Statistical power is one of the most significant indicators to determine
the adequacy of a monitoring design. A well-presented example can be
found in the UNEP Chemicalfs Guidance for a Global Monitoring Programme for
Persistent Organic Pollutants. The Figures 3.1b illustrate data points with
three-year intervals starting from 1972, 1973, and 1974, respectively. All
figures seem to show different trends of the PCB concentration in young
herring samples. The trick is that these figures were made by choosing data
points with three-year intervals using the same data set shown in the next
figure (Figure 3.1a).

This indicates that the data should have been more frequently collected in
order to more accurately detect the PCB trend in the target fish species.
Proper sampling designs with good quality assurance scheme and quality
control indicators are the key to gaining accurate information with limited
resources. Statistical tools and methods should be fully employed in order to
formulate cost-effective sampling plans. In reality, however, a small target
data set is necessary to estimate statistical parameters critical for proper
sampling designs. In cases where preliminary studies cannot be carried out,
the monitoring design should allow for gtrial-and-errorh using the collected
data during the initial phase in order to optimize the environmental
monitoring activities.
In parallel, some research-focused environmental monitoring should be
encouraged to identify unknown and unforeseen risks, develop cost-efficient
technologies, and maintain the monitoring technology and capacity levels.
Without scientists allowed to monitor the Antarcticafs environment, the depletion
of the ozone layers might not have been discovered until the obvious adverse
effects were detected on the ground level.
Adequate environmental monitoring which incorporates the above elements
can both cost-efficiently collect necessary data for policy making, and
assist in identifying us the best available design options. The question
remaining is how we can incorporate the translated result of the environmental
monitoring data into achieving sustainable development. Although the recovery
of ozone layers is not yet visible, the examination of ozone depletions is
very often referred to as one of the most successful cases of cooperation
among scientists and policy makers. Defining adequate environmental
monitoring design elements is one more way scientists and policy makers can
move towards more successful sustainable development. .
In the next issue, assessment criteria which are widely accepted to
determine assessment boundaries will be briefly discussed.
