General Environmental Characteristics
of Greece
Greece, owing to its geomorphology and its fragmented
structure, has an extremely wide range of environments with a vast variety
of natural conditions, including high mountainous areas as well as subtropical
regions. Its mountains, many of which exceed 2 000 m in height, provide
all kinds of conditions with a large variety of woods, fields, and rocks;
its lowlands include wide river deltas and lagoons. Greece has also
many lakes and streams. Some large rivers in northern Greece (the Axios,
Strimon, Nestos, and Evros) enter from the Balkan Peninsula, crossing
two or more countries.
Greece's total coastline amounts to about 15 000 km (7
300 km continental and 7 700 km islands), and it is the longest in the
Mediterranean region. Greece has more than 2 000 islands with rocky
or sandy coasts, duns, caves, bushes, and woods, scattered from the
North Ionian Sea to the southernmost point of Europe (Gavdos Island)
to the easternmost point of Europe (Castellorizon Island). Areas of
more than 2 000 m in depth exist in the Greek seas.
Because of such a diversity of microenvironments, the
country supports some of the richest floras and faunas in Europe. It
contains more than
- 6 000 species of higher plants,
- 110 species of mammals,
- 400 species of birds,
- 100 species of freshwater fish, and
- 60 species of reptiles.
Over the last century, and especially after the 1960s,
a significant move of population toward the coastal areas took place
as these areas experienced increased economic development, mainly through
tourism, industry, transport, and agriculture. This expansion and intensification
of economic development activities has increased environmental problems
and threats to Greece's wildlife, leading to a considerable decrease
in the number of many species. The most serious threats for the fauna
are draining of wetlands, extensive tree cutting, land clearing due
to forest fires, development of coastal housing and tourist installations,
and construction on mountains. Increased emissions of various kinds
of pollutants and pollution of air, water, and soil have also been recognized
as significant problems.
Greece's total population is about 10 million. About 89.7%
of the population lives in the coastal region, which makes up 76% of
the total land area (population density is about 78/km2 or 0.6/km of
coast). Total population of the coastal cities in Greece is about 7
million, but it increases to more than 10 million during the summer
tourism season. Population density in Greece is generally lower than
that of North Europe, but it is high in the Attiki and Thessaloniki
regions where half of the Greek population is concentrated. The urbanization
rate in 1985 was 60%, but it is estimated that by the year 2000 it will
be 68%.
Land use by main category in Greece in 1994 was as follows:
- Arable land 17 %
- Permanent crops 8.2 %
- Wooded areas 22.3 %
- Permanent grassland 13.6 %
- Built-up land 3.7 %
- Other areas 35.2 %
