People’s Republic of Bangladesh, a country in South Asia, formed on the former site of the Pakistani province of East Pakistan. On 26 March 1971, its political leaders announced the creation of an independent state called Bangladesh. The exact founding date is 16 December 1971, when Pakistani troops surrendered to the joint command of East Bengal and Indian armed forces. So adverse is the economic situation in Bangladesh that some have referred to it not as a third world developing nation but as a member of the forth world, the poorest of the poor. Its population is 125.7 million people the eighth largest in the world and one of the most densely populated countries. The capital and largest city is Dhaka (Whyte & Yong, 2010).
The country occupies the eastern outskirts of the Indo Gangetic Plain, and the lower reaches and delta of the Ganges and the Brahmaputra rivers. The country has an area of 144,000 square kilometers and extends 820 kilometers north to south and 600 kilometers east to west (Cumming, 2002). India, Burma, and the Bay of Bengal form the boarders around Bangladesh. The territory represents a flat alluvial plain, dissected by a dense network of rivers. Ganges delta, the Sundarbans, is a broad band of alluvium along the coast of Bay of Bengal. There is a low mountain chain on the border with Myanmar. The country is in a seismically hazardous area (Cumming, 2002).
Typical monsoon climate is characteristic to Bangladesh. Winters are mild, dry and sunny. The average daily temperature in January ranges from 54 degrees to 77 degrees. Summer is hot and rainy, the average temperature of April, the hottest month, is 73 degrees to 93 degrees. Rainy season lasts from June to October, when the monsoon airflow invades from the Bay of Bengal. There may be a noticeable cooling to 43 degrees or less at night. The rainy season usually start in April and ends in October. The rainfall is of critical importance for agriculture in Bangladesh. In case of the absence of the April rain, which softens the ground, it becomes necessary to postpone rice crops and jute, the main market culture crop. Tidal waves, hurricanes and tropical cyclones terrorize the coastal districts of Bangladesh, especially adjacent to the Meghna estuary, from time to time resulting in massive loss of life and serious material damage. The severe flood that occurred in 1998 caused major damage and led to epidemic plague outbreaks when about third of the country was flooded. Innumerable crops were destroyed and millions were left homeless and without potable water. Out ranked by the flood storms, tornados and hailstorms cause less damage and occur most often in March and April (Phillips & Gritzner, 2007).
In Bangladesh, the cultural landscapes are an upsetting topic. Only in a few areas is the natural vegetation preserved. For example, mangroves are common in Sundarbans on the southwest of the country. Sundari trees dominate them. Moist tropical, evergreen and monsoon forests...
