The massive exodus of Venezuelans fleeing to Colombia has become in recent months a humanitarian emergency that affects both countries, which share some 2,200 kilometers of border. It is under the regime of Nicolás Maduro, because of the structural shortage that hits the population. And it is on the other side of the Táchira or Arauca rivers, where the impact of migratory flows, which increased by 110% last year, is increasingly difficult to sustain, according to local authorities. Around 550,000 people, with visa and without papers, arrived with the intention of staying in Colombia. That figure, according to official estimates, can reach one million in July. The colombian president Santos explained that military control will be reinforced at border crossingsand on the trails, the most remote roads become the usual routes of contraband, crime and human trafficking. At the same time, the authorities seek to regulate the entry of Venezuelans in a “controlled, orderly and within the law” manner.
