Bamboo based agroforestry systems are one of the important component to improve socio-economic status, annual income of stakeholders as well as environment friendly. The main aim of the investigation was to find out the role of bamboo in agroforestry system for livelihood and ecological security in North Chhotanagpur division of Jharkhand. After the establishment of bamboo clump of various species like Dendrocalamus strictus, it can survive in water stress condition and showed nice growth and development. In Jharkhand, bamboos are planted on the boundaries of agriculture field for the protection of agriculture crops from high speed wind velocity. Bamboos harvesting can compensate the monetary losses of agricultural crop due to water scarcity. Bamboos are good soil binder due to presence of fibrous root system and hence play an important role in soil and water conservation. It has the potential for effective carbon sequestration, thus helping in countering the emission of greenhouse gases, global warming and climate change. It also lowers the intensity of light and protects from harmful UV radiations. Planting of bamboo lines in east-west direction reduces shade effect, thus decrease the soil and air temperature and solar radiation, which directly influence the soil water evaporation and humidity. Leaves of bamboo were used as fodder, especially for goat. So bamboo based agroforestry plantations can be grown extensively in water stress areas of Jharkhand to boost the socio-economic conditions of farmers and ecological sustainability.
