Warren Buffett's Son Tries to Help Colombia Kick Cocaine Curse Associated Press TIBU, COLOMBIA - With Colombian military snipers in position, Howard Buffett descends from a helicopter and trudges through the wet grass in steel-toed boots chewed through by his dog's teeth. Waiting under a tin-roofed shack is a small group of coca farmers. They've never heard of multibillionaire investor Warren Buffett, but after decades of neglect by their own government they're grateful for the outstretched hand of his eldest son, whom they refer to simply as "the gringo." "There's a saying here: The less you know, the better," said Ruben Morantes, his leathery skin and calloused hands a testament to a lifetime of tillage in one of Colombia's most dangerous territories, where outsiders are traditionally mistrusted. For nearly two decades Buffett has crisscrossed the world,giving away part of his father's fortune to promote food security, conflict mitigation and public safety. But his latest gamble is one of the most daunting yet: helping Colombia kick its cocaine curse. He is focusing on Tibu, heart of the remote, notoriously lawless Catatumbo region bordering Venezuela where Buffett accompanied President Ivan Duque. Tibu has the second-largestcocacrop in all of Colombia -- 28,200 acres (11,400 hectares), according to the United Nations. Drug production andviolence haveskyrocketed in the area since armed groups filled the void left by retreating rebels who signed a peace deal with the government in 2016. Foundation's plans The Howard G. Buffett Foundation has committed to spending $200 million over the next few years to transform the impoverished municipality into a model of comprehensive state building. Plans include strengthening security forces and helping farmerstosecure land titles and substitute coca -- the raw material for cocaine -- with licit crops like cacao. .
