Disputes - international:
stretching over 250,000 km, the world's 329 international land
boundaries separate the 193 independent states and 73 dependencies,
areas of special sovereignty, and other miscellaneous entities;
ethnicity, culture, race, religion, and language have divided states
into separate political entities as much as history, physical
terrain, political fiat, or conquest, resulting in sometimes
arbitrary and imposed boundaries; maritime states have claimed
limits and have so far established over 130 maritime boundaries and
joint development zones to allocate ocean resources and to provide
for national security at sea; boundary, borderland/resource, and
territorial disputes vary in intensity from managed or dormant to
violent or militarized; most disputes over the alignment of
political boundaries are confined to short segments and are today
less common and less hostile than borderland, resource, and
territorial disputes; undemarcated, indefinite, porous, and
unmanaged boundaries, however, encourage illegal cross-border
activities, uncontrolled migration, and confrontation; territorial
disputes may evolve from historical and/or cultural claims, or they
may be brought on by resource competition; ethnic and cultural
clashes continue to be responsible for much of the territorial
fragmentation around the world; disputes over islands at sea or in
rivers frequently form the source of territorial and boundary
conflict; other sources of contention include access to water and
mineral (especially petroleum) resources, fisheries, and arable
land; nonetheless, most nations cooperate to clarify their
international boundaries and to resolve territorial and resource
disputes peacefully; regional discord today prevails not so much
between the armed forces of independent states as between stateless
armed entities that detract from the sustenance and welfare of local
populations, leaving the community of nations to cope with resultant
refugees, hunger, disease, impoverishment, and environmental
degradation
