Parties. In September 2001, the States Parties mandated the GICHD to provide enhanced support to their efforts through the establishment of an Implementation Support Unit (ISU). The ISU's duties include providing support and advice to the Presidency of the Meetings of the State Parties and to Standing Committee Co-chairs, communicating information about the Convention and its implementation, and developing and maintaining a Documentation Centre. On behalf of a group of donors, the GICHD administers its sponsorship programme. In addition, on an ongoing basis, the GICHD provides expert advice to the States Parties on mine clearance, mine risk education, and stockpile destruction. Convention on Certain Conventional Weapons The Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons which May Be Deemed to Be Excessively Injurious or to Have Indiscriminate Effects, also known as the Convention on Certain Conventional Weapons (CCW), was adopted on 10 October 1980, and entered into force on 2 December 1983. The CCW is a framework convention with five protocols, which ban or restrict the use of various types of weapons that are deemed to cause unnecessary suffering, or affect either soldiers or civilians indiscriminately. The weapons covered include: weapons that leave undetectable fragments in the body (Protocol I - 1980); mines, booby-traps and other devices (Protocol II - 1980, amended in 1996); incendiary weapons (Protocol III - 1980); blinding laser weapons (Protocol IV - 1995); and explosive remnants of war (Protocol V - 2003). As of 1 February 2011, 113 States had joined the Convention. The GICHD has observer status at the High Contracting Parties meetings taking place in the framework of the CCW. The Centre has an observer status and assists High Contracting Parties, at their request, in their efforts to minimise human suffering caused by landmines, booby traps and other devices, explosive remnants of war and cluster munitions, which are covered by the ongoing work of the CCW and its Group of Governmental Experts. Since 1999, the GICHD has supported the CCW, primarily by providing expert advice in order to promote the development of, and compliance with, the obligations contained in CCW. In addition, the GICHD is administering the CCW Sponsorship Programme, as mandated by the High Contracting Parties at the CCW Third Review Conference in November 2006. Convention on Cluster Munitions The Convention on Cluster Munitions (CCM) entered into force on 1 August 2010. As of 1 February 2011, 51 States
