Environmental Indicators |
|
|
The Ministry of Environment and Tourism
is currently in the process of defining the National Core a set of
Environmental Indicators (NCEI) that will be used in the future to
monitor the environment. This will form a significant source of
information for decisions in environmental management and will feed
into the President's Vision 2030 process. A great number of indicators
(184) have been suggested for the State of the Environment Report (SoER)
process in Namibia between 1998 and 2001. Seven themes were chosen for
a thorough study of the state of the environment in Namibia:
-
Freshwater resources
-
Social and Economic environment
-
Agriculture and land resources
-
Biodiversity, parks and tourism
-
Mining, industry, energy and
transport
-
Waste management and pollution
control
-
Marine, fisheries and coastal
resources (being compiled)
It is impossible to monitor quite so
many indicators, especially considering the national level monitoring
programmes are extremely resource-intensive. It is therefore, that the
Environmental Monitoring and Indicators Network (EMIN) Workshop was
held on June11-12, 2001, to identified and streamlined the most
effective and efficient indicators for incorporation into Namibia's
NCEI. A total of 142 indicators were used to describe the 10 most
crucial environmental issues (link), out of the collection of 184.
Note: The top five scores are
listed. Were more than one on rank 5 was listed, all indicators
fetching the same score are included. Data availability, sources and
means of monitoring of key data from these indicators will be provided
as soon as the information is available.
