Environmental impact assessment for harbour development in Fainu Island, Raa Atoll

Abstract

The proponent of R. Fainu harbour development project is the Ministry of Housing and Infrastructure. The Ministry is the government's responsible body for the development and regulate the housing and infrastructure of the country. Maldives Transport and Contracting Company (MTCC) has been contracted to undertake the harbour construction work in K Fainu. Maldives Energy and Environmental Company (MEECO) has been contracted to provide preparation services of an Environmental Impact Study (EIA) by (MTCC) for the development of a harbour in IL Fainu Island to accommodate easy access and provide mooring facilities for the vessels. The assessment addresses specific key issues stated in the Terms of Reference (TOR) as agreed between EPA and the Proponent following the Scoping Meeting held on the matter. The Government started development of a harbour in R. Fainu in early 2011. Harbour dredging work started in 2011 but mid-way through the project the dredging work was stopped and the contactor pulled out their equipment after a contractual dispute. The company left creating a mass with uncompleted work and piles of sand and dredged material gathered at the fringes of the dredged areas. Due to this the sand piles accumulated at the harbour area gradually inundated, eroded and spread on the on the reef and lagoon and deposited making the harbour shallow and unusable. At present, apart from a narrow strip, most of the dredged area is completely filled with and remaining deeper areas are hardly usable for mooring vessels. The need for a proper harbour for the island has been recognised by the government and decided to develop a new harbour west of the existing dredged area to provide safe passage and shelter for the vessels operating to and from R. Fainu Island. The study investigates impacts associated with the dredging of R. Fainu harbour basin, entrance channel, harbour protection; tinctures and areas for disposal of dredged material. Also the impact of uncompleted dredging and harbour development work to the reef and lagoon of R. Fainu Island. The proposed harbour has a width of 200ft and a length of 305ft and an entrance channel which will be cut through the reef into the atoll lagoon has a width of 18m and a length of 60m. The harbour basin will be dredged to maintain an avenge depth of -3m with respect to the MSL. A total of approximately 15,000 cubic meters of dredged material is expected to be produced. This material will be used for reclamation on both eastern and western side of the harbour and excess will be used for the nourishment of the beach on the east coast of the island which at present is undergoing severe erosion. The environmental baseline of the island has been established in the approved EIA report of Fainu Island prepared in 2010. Main focus this reports is to document the changes that occurred after the harbour dredging activities conducted in 2011. This EIA has been carried out on the basis that it is necessary to carry out harbour development project at R. Fainu to facilitate socio-economic development and easy access to the island. The project has a number positive and negative impacts. The negative impacts can be effectively mitigated through right actions and implementation of the monitoring plan.
