OCHA ROLAC produces this report in collaboration with humanitarian partners. It covers the period of 13 April to 24 April 2017. This will be the last summary report unless there is a significant change in the situation.

Main Points

  • Sea temperature changes brought on by El Niño have unleashed heavy rainfall throughout Peru, Colombia and Ecuador in the first quarter of 2017.

  • Rainfall persists in some areas but has begun to let up in others.

  • Inland rivers in Peru are receding, but the Tumbes River on the coast continues to overflow near populated areas.

  • The stagnant waters left behind by floods in Peru has led to a rise in reported cases of dengue, chikungunya, Zika and leptospirosis.

  • Colombia continues to suffer more landslides after Mocoa – an 18 April landslide in Manizales has left at least 17 people dead and 66 people missing.

  • In Ecuador, unrelenting seasonal rainfall from the start of 2017 continues to batter communities. Some 1,900 people have been left without homes and over 2,300 have been evacuated.

  • The Manabí province in Ecuador, an already vulnerable area still recovering from the April 2016 earthquake, is among the areas with the highest reported number of affected people.

Situation Overview


Despite the receding water levels of inland rivers, the number of affected in Peru continue to rise, totaling over 1,200,000 affected. As of 21 April, Piura remains the most affected area in Peru, registering 32% of the nationwide totals.

More than 40,000 homes have been destroyed or rendered uninhabitable and 600,000 people across the country are facing dire food security needs.

Going forward, sheltered families are eager to begin restoring their livelihoods in order to recover their homes and lives as quickly as possible.

Despite damage to over 2,000 educational institutions throughout Peru, classes are restarting in rural areas.


While national authorities were still dealing with the aftermath of the 1 April Mocoa landslides that wiped out six neighborhoods, another series of landslides were triggered 600km away in Manizales on 18 April.

As of 20 April, 70 homes have collapsed; due to the threat of further landslides, another 400 homes have been evacuated. The medical personnel of the largest healthcare center in Manizales were also the evacuated due to the damages to the building.

The local area road network suffered damages at 15 key points; repair is ongoing. Twelve schools suspended classes until 20 April, pending a full evaluation of the damages sustained and number of children left without access.

Municipal authorities in Manizales have declared emergencies in several areas and are still evaluating damages and needs. Regardless, they have activated their contingency plans in preparation.


The relentless rainfall in Ecuador has slowly affected over 141,000 people throughout the entire country since the beginning of the year.

The national government declared a nationwide state of emergency to provide immediate aid. At present, 75% of the affected people and 80% of the affected homes are located within the Guayas and Manabí provinces.

The flooding and landslides have hobbled over 100km of the national road network and transportation infrastructure, constantly delaying the delivery of much needed assistance.

Education also remains a priority as 89 schools have reported damages. Countless livelihoods have been placed in jeopardy as over 10,000 hectares of crops have been affected and another 5,000 hectares of crops are all but lost.
