Minister of State for Rural Development Sudarshan Bhagat, in a written reply to Lok Sabha, said "there has been a decline in the number of persondays created in 2014-15."
"MGNREGA is a demand driven programme and the demand for work itself is influenced by various factors such as rainfall pattern, availability of alternative and remunerative employment opportunities outside MGNREGA and prevailing unskilled wage rates," he said.
The minister said that the government remains "actively engaged" with state governments in establishing the system that ensures provision of work as per demand.
He said that the states and Union territories have been asked to take a number of measures like expanding scope and coverage of demand registration system to ensure that the demand for work under MGNREGA do not go unregistered and organise 'Rozgar Diwas' periodically to capture the latent demand under the programme.
