Illustration No. 2. Map of Colombia’s islands in the Caribbean Sea 41. As shown by past experience, the development of major new infrastructure projects in the Wider Caribbean Region could have serious environmental impacts on the marine ecosystem as a result of activities related to their construction and maintenance, and owing to the maritime traffic that such projects may cause or increase. 42. For example, in the case of Malaysia v. Singapore, the International Tribunal for the Law of the Sea concluded that, as alleged by Malaysia, the land reclamation activities carried out by Singapore in the Straits of Johor could cause serious transboundary harm to the marine environment, including deterioration of water quality in sensitive areas and increase of sedimentation. Consequently, the Tribunal considered that, based on prudence and precaution, Malaysia and Singapore should establish a group of independent experts to prepare a report on the effects of those activities. 26 43. Regarding the damage that could occur in this case, it is certain that the construction of any major new infrastructure project in the Wider Caribbean Region could significantly increase the amount of sediments in the marine environment, including the waters and coasts of other States present in the region, such as the Colombian coasts and islands. 26 International Tribunal for the Law of the Sea, Case concerning land reclamation by Singapore in and around the Straits of Johor (Malaysia v. Singapore), Provisional Measures, Order of 8 October 2003. 60
