The PISLM was formulated as part of the Technical Programme of the Caribbean SIDS Programme – an initiative that was recommended at the 14th Session of the Forum of Ministers of the Environment for Latin America and the Caribbean (LAC) held in Panama in November 2003.
The development of the PISLM was spearheaded by a Sub-regional Task Force which suggested the establishment of a support unit to coordinate the activities of the PISLM, and in this regard the Government of the Republic of Trinidad and Tobago was nominated to host the support unit. More specifically, the Task Force identified the Caribbean Network for Integrated Rural Development (CNIRD), located in Trinidad and Tobago, as being the best possible entity for hosting the support office for the PISLM.
CNIRD is currently the only non-governmental regional entity which participates actively in the United Nations Convention to Combat Desertification (UNCCD) meeting and negotiations. The Task Force meeting in May – June 2005 in Barbados, sponsored by the United Nations Environment Programme (UNEP) and the Global Mechanism (GM), has further contributed to the definition of the operational modalities of the Task Force and to the development of a work programme for the PISLM, which includes south-south cooperation, in specific thematic areas, with other countries in the LAC region such as Mexico, Venezuela, Cuba, Argentina, Dominican Republic. Due to institutional and political changes in the various countries and organizations of the region thePISLM has not been fully functional. Furthermore, following the XII Regional Meeting held in Trinidad from July 29th to August 3rd, 2007, a panel was convened under the Chairmanship of the Ministry of Public Utilities and the Environment, Government of the Republic of Trinidad and Tobago.
