Explanation:

Members of Parliament Local Area Development Scheme (MPLAD) is a Central Sector Scheme. 

• It was announced in December 1993 and initially came under the control of the Ministry of Rural Development. Later, in October 1994, it was transferred to the Ministry of Statistics and Programme Implementation. 
• Each year, MPs receive Rs. 5 crore in two instalments of Rs. 2.5 crore each. Funds under MPLAD Scheme are non-lapsable.

Objective

• To enable MPs to recommend works of developmental nature with emphasis on the creation of durable community assets based on the locally felt needs to be taken up in their Constituencies.
• Lok Sabha Members can recommend works within their constituencies and elected Members of Rajya Sabha can recommend works within the State they are elected from.
• Nominated Members of both the Rajya Sabha and Lok Sabha can recommend works anywhere in the country. 
• To create durable assets of national priorities viz. drinking water, primary education, public health, sanitation and roads, etc.
• Since June 2016, the MPLAD funds can also be used for implementation of the schemes such as Swachh Bharat Abhiyan, Accessible India Campaign (Sugamya Bharat Abhiyan), conservation of water through rain water harvesting and Sansad Aadarsh Gram Yojana, etc.
• The Union Cabinet has given its nod to the temporary suspension of MPLAD Funds during 2020-21 and 2021-22 in view of the adverse impact of the outbreak of Covid-19 in India.
