Disputes - international:
stretching over 250,000 km, the world's 325 international land boundaries separate the 192 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 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 directly affects the sustenance and welfare of local populations, often leaving the world community to cope with resultant refugees, hunger, disease, impoverishment, deforestation, and desertification
Refugees and internally displaced persons:
the United Nations High Commissioner for Refugees (UNHCR) estimated that in December 2003 there was a global population of 9.7 million refugees and as many as 25 million IDPs
Illicit drugs:
cocaine: worldwide, coca is grown on an estimated 173,450 hectares - almost exclusively in South America with 70% in Colombia; potential cocaine production during 2003 is estimated at 728 metric tons (or 835 metric tons of export quality cocaine); coca eradication programs continue in Bolivia, Colombia, and Peru; 376 metric tons of export quality cocaine are documented to have been seized in 2003, and 26 metric tons disrupted (jettisoned or destroyed); consumption of export quality cocaine is estimated to have been 800 metric tons
opiates: cultivation of opium poppy occurred on an estimated 137,944 hectares in 2003 - mostly in Southwest and Southeast Asia - with 44% in Afghanistan, potentially produced 3,775 metric tons of opium, which conceivably could be converted to the equivalent of 429 metric tons of pure heroin; opium eradication programs have been undertaken in Afghanistan, Burma, Colombia, Mexico, Pakistan, Thailand, and Vietnam
