Un Millon de Corales por Colombia
Short description of the intervention
The "Un Millón de Corales por Colombia" project is a national initiative aimed at the restoration and conservation of coral reefs across Colombia. Initiated in 2021, this ambitious project seeks to rehabilitate 200 hectares of coral reef by planting one million coral fragments across seven departments in Colombia, spanning both the Caribbean and Pacific regions​ (ref 1,2). It was developed as a response to the significant degradation of coral reefs caused by climate change, coastal development, overfishing, and pollution. These factors have led to the loss of about 80% of coral reefs in the Caribbean region.
The initiative, led by the Colombian government in partnership with organizations such as Conservación Internacional, Parques Nacionales Naturales, Corales de Paz, and several regional environmental authorities, focuses on restoring this vital ecosystem (ref 2). The project encompasses constructing and maintaining coral nurseries and training local community members, including fishermen, as "coral gardeners." These gardeners are taught scientifically proven coral restoration techniques, including microfragmentation and larval rearing methods. A key aspect of the project involves continuous education and involvement of the community and stakeholders to ensure long-term sustainability (ref 4, 5). In Cartagena, the project plays a vital role in the restoration and conservation of coral reefs in this region, which is a key site for the initiative (ref 4).

Objectives of the intervention
Goals of the intervention
- To restore 200 hectares of coral reefs by planting one million coral fragments. (ref 1,2,4)
- To enhance the biodiversity and health of marine ecosystems. (ref 1,2,4)
- To involve local communities actively in coral reef restoration, creating sustainable economic opportunities, through environmental stewardship and conservation jobs​ (ref 1,2,4)
- Contribution to the national goal of coral restoration with 1,000,000 cultivated fragments in approximately 203 nurseries. (ref 3)
- Involvement of 60 coral gardeners in areas of the Caribbean and Pacific regions of Colombia. (ref 3).
Implementation activities and NBS focus
Implementation activities
- With the participation of environmental authorities, stakeholders, and local communities, the workshop "Un Millón de Corales por Colombia was organised: Defining Actions for the Ecological Restoration of Coral Reefs" was held in Cartagena de Indias (ref 4).
- The coral gardeners learned a technique called fragmentation and microfragmentation. Once the fragments are ready, they are transplanted to reef areas in need of restoration. After cultivation, the gardeners transported the fragments to key locations, most of which are within protected areas among other maritime-continental and insular areas in the country. In addition, over 150 people have been trained and now have the knowledge to replicate this large-scale and unprecedented initiative (ref 3)
- An intensive eleven-day workshop was conducted in June 2022, during which Ecomares, with the support of National Parks, Conservation International, CEINER, and Diving Planet, set up three tables with over 13,500 micro-fragments of eight reef-building species. Since then, Ecomares has carried out monthly maintenance and monitoring of these nurseries (ref 5). A significant aspect of the project is the involvement of local communities and their training in coral restoration techniques. "More than 150 people have been trained and now have the knowledge to replicate this large-scale and unprecedented initiative"​ (ref 3).

Impacts, benefits
Description of environmental benefits
-Expected enhanced protection and restoration of coastal and marine ecosystems: To date, the ‘One Million Corals for Colombia’ project has produced 735,822 new fragments of more than 30 coral species in 12 coral areas of the Colombian Caribbean and Pacific, including the Rosario and San Bernardo National Parks, Tayrona, Isla Fuerte, Utría, Gorgona, and the Seaflower Biosphere Reserve, among others. Of these obtained fragments, 91,191 have been transplanted back to the reef in priority areas for restoration. 38,136 coral fragments were planted in the marine ecosystem of Cartagena, Colombia, in the sectors of Corales del Rosario (18,087), Barú (11,165), Isla Palma (5,644), and Isla Fuerte (3,240). Coralízate is a coral restoration activity that took place between May 25 and June 8, during which 113,136 coral fragments were transplanted and cultivated, exceeding the goal of 100,000 set by the authorities, partners, and communities, according to information from El Universal. (ref 8).
-Expected increased conservation or restoration of ecosystems: The restoration efforts have led to significant improvements in marine biodiversity. The cultivated corals have begun to grow and merge into larger colonies, which can then be transplanted to reefs to restore the ecosystem. "In a year, we will have an entire colony that we can transplant to a reef to restore the ecosystem"​ (ref 6).
-Expected increased protection of threatened species: The project focuses on reviving critically endangered coral species, such as the elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis). These species have been grown in nurseries and then transplanted to key locations. "Thanks to the permanent and diverse coral nurseries maintained by the Center, experts were able to identify the exact day and time of reproduction of the nearly extinct elkhorn and staghorn corals, something unprecedented in Colombia" (ref 6)
Description of economic benefits
-Achieved increase of green jobs (e.g. paid employment positions): Involvement of 60 coral gardeners in areas of the Caribbean and Pacific regions of Colombia. (ref 2).
Description of social and cultural benefits
-Achieved increased knowledge of locals about local nature: The project also has a strong educational component, involving training for over 150 people on coral restoration techniques and the importance of reef conservation. This knowledge helps local communities understand the value of coral ecosystems and equips them to carry out future restoration efforts​ (ref 3, 6).

Description of locals satisfaction with the project
A local fisherman, Casemiro Newball, expressed the impact of the initiative: “This initiative had a very important impact on the restoration of marine life on the island because, in the areas where restoration has been done, the fish have returned, but it was also a mechanism to employ local communities, who got involved in recovering the richness of the depths” (ref 3).
Scientists agree that this restoration effort should be part of long-term projects and monitoring (ref 3).
