Nosy Be

The island, like most of Madagascar, suffers from an extreme level of uncertainty linked to crime and violence. Rumours quickly turn into accusations in Madagascar, and lynchings are common, even for allegations related to traffic accidents or theft. On October 3, 2013, the body of an 8-year-old boy was discovered at the beach of Ambatoloaka on the island. The condition of the body was poor after one week in the water, and a rumour was spread that the child had been murdered by Western organ-trafficking tourists. The uncle of the boy, a local named Zaidou, was detained by the local police for questioning, but a violent mob gathered to storm the local jail to punish the supposed murderer.[9]

As the uncle was not found, the anger of the mob turned to the Westerners having been in contact with the person, French tourists Sébastien Judalet and Roberto Gianfalla. Judalet was found and dragged from his hotel to the beach of Ambatoloaka, where the large mob repeatedly hit him with sticks and stones. The police received at least five calls from bystanders or expatriates but did not respond. Two police officers actually joined the mob, one of which who was filming the lynching on his smartphone.[10] After three hours of torture and humiliation, the naked and bleeding tourists were put into car tires and thrown alive into a bonfire on the beach.[9] On the afternoon of October 3, 2013, the uncle Zaidou was found driving on the island. A mob of several hundred quickly lynched him by burning him alive on a public street next to a mosque.

Both events were filmed by the bystanders, publishing the murders on the internet. In spite of this mass of evidence, the local justice took two years of investigation to finally convict 4 members of the mob to lifetime imprisonment and 6 others to shorter sentences; 26 suspects in custody were released without charge as well as the two police officers.[11] A local politician, Joseph Yoland, was accused of inciting the killings on his radio station at the island, but the charges were dropped when the court allegedly was unable to retrieve any recordings of the aired shows that evening.[12] Following the events, the French authorities warned travellers for "high risk of assaults, that could be extremely violent",[13] U.S. travellers are also advised "[to] be aware of the potential for mob violence and 'popular justice' that is sometimes directed towards foreign nationals.".[14] The lynching in Nosy Be is a rare public murder of expatriates in Madagascar; most lynchings concern locals. However, expatriates are frequently subject to kidnapping and extortion, such as the January 2015 kidnapping of a 12-year old French child outside of his school,[15] and two separate kidnappings of French citizens of Indo-Pakistani origin in April 2016 that triggered the intervention of the French police tactical unit GIGN in Madagascar.[16]

Omura's whale off Nosy Be

Recent studies indicate that adjacent waters around the channel between Nosy Be[20] and Madagascar host a habitat for notable number of Omura's whale, and this has allowed researchers to conduct field studies targeting this rare species for the first time.[21][22]

Nosy Be has a tropical monsoon climate. It is most humid in summer (December, January, February). The Tsaratanana massif partially protects the island from the strong north-east winds affecting the region in August or during tropical depressions. The wet season lasts from October until the beginning of May, followed by a relatively short dry season that lasts through September. As characteristic of its climate however, it still sees moderate amounts of precipitation even during this time. Daytime temperatures remain fairly steady throughout the year, hovering around 30 °C (86 °F), while the nights are slightly cooler during the dry season.
