Disputes - international:
stretching over 250,000 km, the world's 322 international land boundaries separate 195 independent states and 71 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; most maritime states have claimed limits that include territorial seas and exclusive economic zones; overlapping limits due to adjacent or opposite coasts create the potential for 430 bilateral maritime boundaries of which 209 have agreements that include contiguous and non-contiguous segments; boundary, borderland/resource, and territorial disputes vary in intensity from managed or dormant to violent or militarized; undemarcated, indefinite, porous, and unmanaged boundaries tend to 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 and internal displacement of the estimated 6.6 million people and cross-border displacements of 8.6 million refugees around the world as of early 2006; just over one million refugees were repatriated in the same period; other sources of contention include access to water and mineral (especially hydrocarbon) resources, fisheries, and arable land; armed conflict prevails not so much between the uniformed 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

Refugees and internally displaced persons:
the United Nations High Commissioner for Refugees (UNHCR) estimated that as of the end of 2012 there were 45.2 million people forcibly displaced worldwide; this includes 15.4 million refugees, 937,000 asylum seekers, and 28.8 million conflict IDPs (another 32.4 million IDPs were displaced by natural disasters); the UNHCR estimates there are currently 10-12 million stateless persons (2012)

Trafficking in persons:
current situation: approximately 800,000 people, mostly women and children, are trafficked annually across national borders, not including the millions who are trafficked within their own countries; at least 80% of the victims are female and up to 50% are minors; 75% of all victims are trafficked into commercial sexual exploitation; almost two-thirds of the global victims are trafficked intra-regionally within East Asia and the Pacific (260,000 to 280,000 people) and Europe and Eurasia (170,000 to 210,000 people) (2012)

Illicit drugs:
cocaine: worldwide coca leaf cultivation in 2007 amounted to 232,500 hectares; Colombia produced slightly more than two-thirds of the worldwide crop, followed by Peru and Bolivia; potential pure cocaine production decreased 7% to 865 metric tons in 2007; Colombia conducts an aggressive coca eradication campaign, but both Peruvian and Bolivian Governments are hesitant to eradicate coca in key growing areas; 551 metric tons of export-quality cocaine (85% pure) is documented to have been seized or destroyed in 2005; US consumption of export quality cocaine is estimated to have been in excess of 380 metric tons
opiates: worldwide illicit opium poppy cultivation continued to increase in 2007, with a potential opium production of 8,400 metric tons, reaching the highest levels recorded since estimates began in mid-1980s; Afghanistan is world's primary opium producer, accounting for 95% of the global supply; Southeast Asia - responsible for 9% of global opium - saw marginal increases in production; Latin America produced 1% of global opium, but most was refined into heroin destined for the US market; if all potential opium was processed into pure heroin, the potential global production would be 1,000 metric tons of heroin in 2007
