A feasibility and effectiveness assessment was conducted for six adaptation strategies often used and recommended by the UN to respond to malnutrition risks that combined a literature review and expert judgment assessment of 80 peer-reviewed studies  and Singh et al. ). Nineteen indicators of six dimensions of feasibility  were considered. The lead time to initiate and the expected longevity of each option were examined. Feasibility was defined as how significant the reported barriers were to implement a particular adaptation option. Highly feasible options were those where no or very few barriers were reported. Moderately feasible were those where barriers existed but did not have a strong negative effect on the adaptation option . Low feasibility options had multiple barriers reported that could block implementation. Effectiveness ratings were based on expert consultation and reflected the potential of the adaptation option to reduce risk. The final effectiveness and feasibility scores were categorised as high, medium or low and reflect the combined results of all studies for a given adaptation option .
