There are a number of international law treaties that pertain to mines, cluster munitions and Explosive Remnants of War (ERW) :

The Geneva International Centre for Humanitarian Demining (GICHD) contributes to the development and implementation of those instruments of international law that address the problem of explosive hazards. During convention related meetings, such as Meetings of States Parties, Review Conferences, Intersessional Meetings and Meetings of Experts, the GICHD provides expert input to facilitate informed discussions and negotiations. The Centre also provides administrative and logistical support to the Work Programmes of the Implementation Support Units of the APMBC and CCM. It further administers the Sponsorship Programmes of the APMBC and of the CCW. These programmes strengthen the implementation of these instruments, promote universalisation and ensure widespread participation in related meetings. 

Hosting and supporting the Implementation Support Units

ISU - APMBC | The APMBC Implementation Support Unit (ISU-APMBC) was established in 2001 based on an agreement reviewed in 2011. The ISU-APMBC derives its mandate from the States Parties and is hosted by the GICHD, which provides it with administrative and logistical support.

ISU - CCM | As agreed between the States Parties and the GICHD, the Centre hosts the ISU of the CCM since May 2015, providing infrastructure and administrative support for ISU operations. As a joint collaboration of the GICHD and the ISU CCM, the third edition of the “Guide to Cluster Munitions” was released in April 2016.
