Unscientific disposal of house hold waste and floral offerings of the temple, prevalence of diesel based irrigation system and dependence on coal based electric energy have been the major environmental concern in India.
Dr. Rajendra Prasad Central Agricultural University has initiated several measures to protect the environment by introducing solar based irrigation systems for challenged ecology, solar based power supply to its different units and management of household waste into vermicompost. For better waste management, point source segregation of biodegradable and non-biodegradable wastes is in practice. Compostable waste and cow dung from own animal farm in equal proportion (50:50), arranged in windrows, inoculated with epigeic earthworm species @2 kg per ton of material at optimum moisture and temperature under the shade. Prepared cast is utilized by farmers and other stakeholders. The conversion of house hold waste during last one and half year resulted productions of 1400 Quintal of vermicomposting, 7.93 Lakh numbers of worms, engagement of –man powers and generation of revenue of 11 lakh. This concept is further strengthened by utilizing the floral offerings of major Lord Shivas Temples located at Baidyanath Dham (Deoghar) and Garibnath Temple, Muzaffarpur into vermicompost and distributions of Tulsi Plant grown in such vermicompost to the Devotees for environmental cleaning through waste management and environmental air purification through planting of Tulsi plant. The University has developed- boat based solar powered pumping system , adopted solar tree technology for irrigation of flood prone areas and and Tractor trailor based mobile solar powered pumping system for Diara and TAL areas to reduce dependence on the diesel based irrigation system from the river but also channelize bank of rivers towards agriculture production systems during pre and post monsoon season. Establishment of bio-diversity Park, eco-club, planting and nurturing of one plant by each student of the university has further led the university towards green campus.
