The POSHAN Abhiyaan, also known as the National Nutrition Mission, adopts several strategies to combat malnutrition in India. Two of the key strategies include inter-sectoral convergence for better service delivery and the use of technology (ICT) for real-time growth monitoring of women and children. The search results confirm that the Abhiyaan effectively operationalizes inter-sectoral convergence through institutional mechanisms at multiple levels. Additionally, technology is leveraged for real-time monitoring of health and nutrition programs, as indicated by the use of ICT tools like the ICDS-CAS (Integrated Child Development Services-Common Application Software). Therefore, both strategies mentioned in the question are indeed part of the POSHAN Abhiyaan's implementation approach.
