A judge in Puerto Nare, Antioquia, ordered the regional environmental authority Corantioquia to adopt measures to control hippos in the Nare River after ruling on a tutela action filed on behalf of 23 students who travel the river daily to attend classes at two rural schools.[^1]

The tutela action was filed by lawyer Juber Martínez Giraldo and community leader Norman Ferney Vélez Daza in representation of the students against Colombia's Ministry of Environment, Corantioquia, the Government of Antioquia, and the Mayor's Office of Puerto Nare.[^2] The judicial ruling placed Corantioquia at the center of direct responsibilities.[^6]

Corantioquia and Cornare, the two regional environmental authorities, said that managing the expanding hippo population in the Magdalena Medio region exceeds their financial and logistical capacities.[^3] The read here is that the ruling shifts the burden onto a single authority that has already said it cannot handle the problem alone, and the students' safety on the river remains the immediate concern.
