Costa Rica has been subject to territorial border disputes with Nicaragua, stemming from turmoil concerning the election of rival political leaders in the 1970s and 1980s, advocate of democracy Don Pepe Figueres and the Nicaraguan dictator, President Luis Somoza Debayle. Due to the conflict, landmines began infiltrating Costa Rica following occupation of Sandanista rebel military bases in northern Costa Rica. For over 12 years, Nicaragua populated Costa Rica's northern border with landmines because of the disputes.
Many believe that Costa Rica was never a manufacturer of landmines. The country has never publicly claimed to manufacture or stockpile landmines. Due to the border dispute between Costa Rica and neighboring Nicaragua, however, Costa Rica's Ministry of Security's Mine Clearance program had estimated that the northern border contained upwards of 3,000 landmines. The majority of the affected landscape in Costa Rica had been used primarily for agriculture. Costa Rica's Chief of the Mine Clearance Program announced that the PP-Mi-Sr II, the M-14, and the PMD-6 landmine types had been found throughout Costa Rica.
According to the most recent available statistics, no new mine casualties were reported in Costa Rica in 2002. That same year, the Organization of American States (OAS) provided some assistance to the country's three known mine survivors through the OAS/Mine Victim Rehabilitation Program. Currently, Costa Rica does not have a landmine victim assistance program nor a clinic to treat landmine injuries. However, the Costa Rican Social Security Office has constructed a medical camp with a staff of personnel, which has helped the populations residing near mine-infested areas. The OAS has stated that mine risk education continues in the areas of Crucitas, Jocote, Las Tiricias, San Isidro, Pocosol, Medio Queso and La Guaria. Mine risk education programs include educating the young, utilizing public talks and distributing educational materials.
Costa Rican demining utilizes assistance from two international supervisors, 41 professional deminers and four mine-detecting dogs (MDDs). The Unit of Sappers of the Costa Rican Security Force employs numerous indigenous personnel for mine action.
Funding from the United States has helped Costa Ricans to obtain mine clearance training, purchase mine detection equipment and MDDs, enhance medical evacuation capabilities, establish a communications base and receive survivor assistance and medical supplies. The United States completed its obligation to Costa Rica in 2001 after the country reached the sustainment phase in its humanitarian demining program. According to the Assistance Mission for Mine Clearance in Central America (MARMINCA), as of June 2004, Costa Rica had discovered over 4,000 metallic objects and had destroyed 341 mines. In total, Costa Rica has cleared 131,903 square meters of land, which is now habitable and usable by the population. The Inter-American Defense Board (IADB) and the OAS have declared that Costa Rica is the first country in those respective programs to be free of landmines.1 Costa Rica is considered a model country of the positive impact of organized demining programs.
In December 2002, Costa Rica was able to declare itself free of landmines, boasting extremely low landmine accident/casualty numbers. Under the stipulations of the Ottawa Convention, which the country signed in 1997, Costa Rica was required to clear all of its landmines by 2009, making its recent accomplishment that much more substantial.
