Introduction Countries with access or no access to open seas forms the different geographical location of coastal peninsula, island or landlocked state, respectively. Sea and ocean environment is different from land environments in terms of features. An area of ocean is three times larger than the land. Water bodies are spherical cohesion while the land suffers fragmentation of space. Water bodies have an inclusive position and land area has a peripheral one. Sea power is one of the most important aspects of the state’ s national power. Most of the world powers (past and present) have coastal and sea geographical positions. The sea position provides countries many options in all economic, political, cultural, and social dimensions, which continental countries are deprived of them. Continental and land-based military powers have limited military power. Traditional and modern sea powers have a spherical function, in view of their respective characteristics of the marine environment. Most of these countries have always had a maritime trade approach and have supported open economic policies. The sea powers are present in the seas in economic, military, political and legal forms. Sea power is not considered proper in evaluating national power because it includes different factors. Sea power is the only aspect of national power that can be present in different water bodies, and is not affected land and air power limitations. Many variables and elements affect states’ sea power. Various factors such as human, geographical-territorial, technological, economic, political, etc. shape the sea power of the states. These factors interact with each other. This article investigates the role of human geographic factors in the states’ sea power.
