An unconsolidated deposit of semi-carbonized plant matter is peat and usually found in water-saturated environments and has a persistently high moisture content. In Bangladesh, haor is peat dominant area and this area is largest peat reserves areas of Bangladesh. Peat is one of the most important mineral resources around the world. For utilization of peat like other countries, it is necessary to know the energy and fertility potential and develop a sustainable management strategy of peatlands in Bangladesh. The study was mainly focused on the heating and fertility potentials of peat available in Bangladesh and also focused on approaches to sustainable management strategy of peatlands in Bangladesh. The study was carried out at haor based Katiadi and Mohanganj upazilas of Kishoreganj and Netrokona districts of Bangladesh, respectively. After collection of peat sample, it has been tested in several laboratories like Agrivarsity Humboldt Soil Testing Laboratory of BAU and Institute of Fuel Research and Development (IFRD), BCSIR, Dhaka, Bangladesh. Some selected physical properties of peat were also tested at Green Energy Knowledge Hub of BAU. According to the physical and chemical analysis of collected peat, it has heating and organic fertility potentials. Calorific value of peat (2638 kcal/kg) was found higher than that of cow dung (1797 kcal/kg) and rice husk briquette (2546 kcal/kg). Minor scale rural community of haor uses peat as domestic cooking fuel and supply to small agro-farm. Few agro-farms mix some ingredients like animal manures with peat for making balance organic fertilizer. It is necessary to analyze peat in detail, for using in different purposes especially for brick fields which will reduce the cutting of forest and save the environment. Government of Bangladesh should take a major peat development programme to find out the systematic approaches for sustainable use and conservation of peat and peatlands in Bangladesh.
