Hola mapeadores de OSM!

Es un placer presentarles la primera tarea del projecto: #3302 - #CARTOCOSTA-URABÁ (Turbo, Colombia) Lado oriental.

Este proyecto es financiado por: Humanitarian OpenStreetMap Team (HOT) #Microgrant Program.

Este permitirá mapear humedales costeros en el golfo de Urabá para ayudar a los planificadores territoriales y a las comunidades de pescadores en su respuesta ante amenazas de inundación en el área.

El área de trabajo está ubicada en el Municipio de Turbo (Departamento de Antioquia, parte sur del Caribe colombiano)

El objetivo del proyecto es mapear una línea de costa de aproximadamente 190 km de largo y una franja costera de 2-3 km.

Realizaremos mapatones de entrenamiento el jueves 13 y el viernes 14 de julio en la Facultad de Ingenierías de la Universidad de Antioquia (sala de computos, 3er piso del bloque 20), Medellín, Colombia.

Se invita a los mapeadores remotos a unirse.

Estén pendientes de mapatones futuros y de noticias!

Hello OSM mappers,

It is a pleasure to announce the first mapping task of project #3302 - CARTOCOSTA-URABÁ (Turbo, Colombia) East coast.

It is funded by the Humanitarian OpenStreetMap Team (HOT) #Microgrant Program.

This Project will enable mapping of coastal wetlands in the Urabá Gulf to help planners and the local fishing community to respond to flooding hazards in the area.

This area is located in Turbo Municipality (Antioquia State, Colombia, Southern Caribbean).

The project will map over 190 km of coastline, including 2-3 km width inland.

Training Mapathons will be held on Thursday 13 and Friday 14 July at Universidad de Antioquia, Medellín, Colombia.

Remote OSM mappers are welcome to join.

Stay tuned for further mapathons and news.

Turbo is the Southern-most municipality in the Caribbean coast of Colombia, yet poorly known nation- and world-wide. Such invisibility contrasts with the beauty of tall mangroves in wild areas and with the numerous fishermen settled in small villages along a ca. 200km-coastline. In addition, the urban area of Turbo, with nearly 50,000 inhabitants, is sustained by both the services provided by mangroves in the proximity and afar, and most importantly by the small-scale fishery providing over 50 species of fish and shellfish. Turbo is a vibrant small city populated by african-descendants coming from the Pacific (Chocó) region of Colombia, amerindians from the Panamian Darién and the northern Andes, and mestizos from the european arrival. Fishermen and their families by far may account for a 1% of Turbo’s population in both rural and urban area.

Despite the foundation nearly two centuries centuries ago, the urban area has sprawled since the 1970’s as a consequence of peri-urban settlements promoted by migration from rural areas as a consequence of the armed conflict in Colombia (1,2). Such settlements occurred in lowlands, usually in the intertidal fringe, at expense of the native coastal wetlands (1, 2). Therefore, mangroves and freshwater grasslands and forests were decimated in the vicinity of Turbo. In contrasts, these types of wetlands remain as fringes or large patches in the rural areas, and coexist with small fishing villages.

The Caribbean Sea is seen in the imagination of most people as an area of clear waters, paradise islands, and peaceful beaches. In the best of the instances, it is also seen as the land of dwarf mangroves border-lining creeks on coral islands.

However, the Souhtern-most tip of the Caribbean Sea located in Colombia close to the border with Panama is a different story. This location is known in world maps as the Urabá Gulf or the Darién Gulf. It is a U-shape entrance of the sea into South America formed by the clash of the tectonic plates of the Caribbean, Nazca and the Pacific. Such a geological activity gave rise to the Isthmus of Panamá and created a fracture in a North-South direction that formed the main axis of the Urabá Gulf. Therefore, this gulf is surrounded by two main coastal ridges: the Serranía del Darién to the West and the Serranía de Abibe to the East. Both mark the limits of the geological plates, the Isthmus (or Meso America) and South America, respectively.

Such an impressive geological history not only formed a coastline with a distinctive landscape from the rest of the Caribbean in the neighboring areas: Panama and Colombia. It also promoted a major change in the hydrology of an ancient river, the Atrato. Being formed in the upper part of the Western Cordillera of Colombia in the Pacific side of South America, one of the rainiest places on Earth (annual rainfall: >8 meters!), the Atrato river drains a world-class discharge. Such discharge once ran to the Pacific before of the closure of the Panama Isthmus. But nearly 3 million years ago the course of this magnificent river was diverted to the North and ended discharging into the Urabá Gulf, now the Southern-most end of the Caribbean Sea.

The change caused the mangroves to flourish and growth to a point not seen in the Caribbean coast of Panama and Colombia.

This unique land has been subject of a mapping effort aimed at understanding its biogeographic features and history.
