A Biosphere Reserve attempts to harmonize development, the welfare of the people, and the maintenance of a healthy ecological system (UNESCO 1996a). The investigation of this study can highlight the sustainability deficiencies that could potentially hinder a biosphere reserve designation on the northeast coast of St. Lucia, W.I. The research focus and findings have the potential to address a matter of key concern in St.Lucia''s sustainability planning efforts. Major findings of the analysis included a weak land development process on the island; its lack of rigorous policies, the absence of a national land use plan and low public participation; all hindrances to sustainability and to proper environmental management. The northeast coast is not yet ready to be designated a Biosphere Reserve as it must overcome certain challenges impeding sustainability. The major arguments point to the need for stronger policies for conservation, land use, and equitable economic benefits from the tourism industry. The resolution of many of these issues lies in the structural changes of governance, constitutional reform, empowering the local citizenry, and decision-making that is more participatory.
