Book excerpt: A total of 2,463 actual or attempted acts of piracy were registered around the world between 2000 and the end of 2006. This represents an annual average incident rate of 352, a substantial increase over the mean of 209 recorded for the period of 1994 1999. The concentration of pirate attacks continues to be greatest in Southeast Asia, especially in the waters around the Indonesian archipelago (including stretches of the Malacca Straits that fall under the territorial jurisdiction of the Jakarta government), which accounted for roughly 25 percent of all global incidents during 2006. Seven main factors have contributed to the general emergence of piracy in the contemporary era. First and most fundamentally, there has been a massive increase in commercial maritime traffic. Combined with the large number of ports around the world, this growth has provided pirates with an almost limitless range of tempting, high-payoff target. Second is the higher incidence of seaborne commercial traffic that passes through narrow and congested maritime chokepoints. These bottlenecks require ships to significantly reduce speed to ensure safe passage, which dramatically heightens their exposure to midsea interception and attack.
