iii) Based on the information collected and assessed under the other objectives,  provide a list of possible actions to be implemented by EFSA and at least five  high level recommendations for multi-annual, multi-partner studies or projects,  each supported by a SWOT or equivalent analysis.  i) Identify opportunities for communication in the area of systems-based ERA at  European level, relying on social research methods and tools that provide  societal  insights  (incl.  awareness,  understanding,  risk  perceptions,  expectations, sentiment analysis). Such insights should be generated to inform  any future communication and engagement efforts in this area of work. i) Provide a refined problem formulation to address the objectives of the theme  paper (Annex 4) to be achieved focusing on: ii) Provide a refined workplan (milestones, timelines, etc) describing and  potentially refining the methodology proposed in the offer and that will be used  to achieve all subsequent objectives (2-7). 10  Objective 7: Identifying communication opportunities  OBJECTIVES FOR LOT 2 • Development of roadmap for action on new approach methodologies in  risk assessment Objective 1: Refining the problem formulation proposed in the offer The  main objective of the roadmap for action for this lot is to define EFSA priorities  regarding the incorporation of new approach methodologies (NAMs) in regulatory hazard  assessments and risk characterisations of chemicals in food and feed, and to define a  multiannual strategy for increasing the use of NAMs in EFSA human health risk assessment  to minimise the need for animal-based verification studies, so that by 2027 the large  majority of EFSA requests for additional data are based on NAMs. The following objectives  should be read alongside the theme paper on new approach methodologies in risk  assessment ( Annex 4 ). The specific objectives  for lot 2 are: a) understanding mechanistic-based risk characterisation of chemicals and  evolution of the risk assessment paradigm to identify susceptible population  groups; b) identifying key issues for understanding and evaluating the outcome of NAM- based studies and their relevance for the risk assessment; c) principles for  ‘ validation and acceptance ’  in the regulatory science context of  non-standardised studies with ad-hoc design.
