Charitable Trust funds small scale assistance in the education and training sector. Armed forces There are two police wings: the Vanuatu Police Force (VPF) and the paramilitary wing, the Vanuatu Mobile Force (VMF). Altogether there were 547 police officers organised into two main police commands: one in Port Vila and one in Luganville. In addition to the two command stations there were four secondary police stations and eight police posts. This means that there are many islands with no police presence, and many parts of islands where getting to a police post can take several days. There is no purely military expenditure. In 2017, Vanuatu signed the UN treaty on the Prohibition of Nuclear Weapons. Administrative divisions Vanuatu has been divided into six provinces since 1994. The names in English of all provinces are derived from the initial letters of their constituent islands: Malampa (Malakula, Ambrym, Paama) Penama (Pentecost, Ambae, Maewo – in French: Pénama) Sanma (Santo, Malo) Shefa (Shepherds group, Efate – in French: Shéfa) Tafea (Tanna, Aniwa, Futuna, Erromango, Aneityum – in French: Taféa) Torba (Torres Islands, Banks Islands) Provinces are autonomous units with their own popularly elected local parliaments known officially as provincial councils. They collect local taxes and make by-laws in local matters like tourism, the provincial budget or the provision of some basic services. They are headed by a chairman elected from among the members of the local parliaments and assisted by a secretary appointed by the Public Service Commission. Their executive arm consists of a provincial government headed by an executive officer who is appointed by the Prime Minister with the advice of the minister of local government. The provincial government is usually formed by the party that has the majority in the provincial council and, like the national government, is advised in Ni-Vanuatu culture and language by the local council of chiefs. The provincial president is constitutionally a member of the electoral college that elects the President of Vanuatu. The provinces are in turn divided into municipalities (usually consisting of an individual island) headed by a council and a mayor elected from among the members of the council. Economy The four mainstays of the economy are agriculture, tourism, offshore financial services, and raising cattle. There is substantial fishing activity, although this industry does not bring in much foreign exchange. Exports include copra, kava, beef, cocoa and timber; imports include machinery and equipment, foodstuffs,
