Which one of the following is not a strategy in the Rainfed Area Development (RAD) scheme of India?

The Rainfed Area Development (RAD) scheme, a sub-component of the National Mission for Sustainable Agriculture (NMSA), focuses on areas dependent on rainfall rather than canal-fed irrigation. Its strategies include integrated/diversified farming systems combining crops, livestock, fisheries and horticulture; soil health management; and cluster-based, area-specific interventions to enhance productivity and farmer income in rainfed regions. Optimizing canal irrigation is not a part of RAD because RAD by definition targets non-irrigated, rainfed areas; canal irrigation issues fall under other schemes such as PMKSY-AIBP. Hence (d) is the answer.
