Princess Diana was a big advocate of removing land mines. An Israeli company called Geomine has made a system that can detect where mines are from the air by using a hyperspectral camera which captures the unique nitrogen oxide signature in the soil emitted by the explosive device. Video can be seen here. The next development soon to come out is to do this by drone and send another drone to take the mines out.
Some $450m was allocated to mine removal in 2017 which is usually done using very inefficient techniques. In 2016, more than 232,000 antipersonnel mines and some 29,000 antivehicle mines were destroyed Geomine believes the speed of its system creates massive efficiencies in terms of cost, safety and lives saved.
There were 8,605 land mine casualties caused in 2016, up from 3,450 in 2014. 42% were children. 84% male. 110,000 casualties since 1999. Casualties were recorded in Afghanistan, Algeria, Angola, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina (BiH), Cambodia, Cameroon, Chad, Chile, Colombia, Croatia, Democratic Republic of the Congo (DRC), Egypt, Guinea-Bissau, India, Iran, Iraq, Israel, Kuwait, Lao PDR, Lebanon, Libya, Mali, Mozambique, Myanmar, Namibia, Niger, Nigeria, Pakistan, Palestine, Philippines, Poland, Russia, Rwanda, Serbia, Somalia, South Korea, South Sudan, Sri Lanka, Sudan, Syria, Tajikistan, Thailand, Tunisia, Turkey, Uganda, Ukraine, Vietnam, Yemen, Zimbabwe, and four other areas Kosovo, Nagorno-Karabakh, Somaliland, and Western Sahara.
Wishing Geomine every success.
