This is a critical review to discuss the best practice approaches to mortuary operations in preparation for and the response to natural, mass fatality, disaster events, as identified by a review of published articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) Statement guided the identification of potential articles to use in this critical review. Subsequent searches were also conducted to identify articles relating to heat wave, and flood mortality. All identified peer-reviewed studies published in English which discussed the preparation and response of mortuaries to mass fatality natural disasters occurring in developed countries were included. Using the PRISMA-P method of identifying articles, 18 articles were selected for inclusion in this review. Although there are numerous articles which describe the mortuary response to mass fatality incidents, few articles analyzed the response, or discussed the roles which supported and enabled the organization to undertake the task of identifying disaster victims. It is thus difficult to determine objectively if the actions and activities outlined in the articles represent best-practice.
The extent of bottomland hardwood forests in the Lower Mississippi Alluvial Valley (LMAV) has diminished, and federal programs like the Conservation Reserve Program provide incentives to afforest marginal agricultural areas with oaks to provide ecosystem services. Remote sensing technologies, like light detection and ranging (LiDAR), can be used to estimate biomass of these stands to potentially allow landowners to take advantage of carbon markets, but data are expensive to collect. Therefore, we determined whether freely available low-density LiDAR data could capture variability in tree- and stand-level characteristics in the LMAV, including aboveground biomass. We found that multiple regression LiDAR models captured more variability in tree-level than stand-level parameters and including soil type generally improved models. Model r2 values predicting tree and stand parameters including tree height, height to the live crown, quadratic mean diameter, crown area, trees per hectare, stand basal area, and stand biomass ranged from 0.34 to 0.82 and root mean square percent error (RMSPE) ranged from 7% to 36%. Specifically, models for stand biomass had an RMSE of about 19 Mg/ha or about 19% of mean values across sites. Therefore, freely available LiDAR data was useful in evaluating afforested bottomland oak sites for tree- and stand-level structural components in the LMAV. Study Implications: Programs including the conservation reserve program (CRP) incentivize farmers to plant marginal farmland in forests and other land uses to provide wildlife benefits. In particular regard to mitigating climate change, afforestation could additionally uptake carbon and allow landowners to potentially take advantage of carbon markets. However, carbon amounts are difficult to measure over large areas in an efficient and cost-effective way. Remote sensing technologies, like LiDAR, could estimate forest carbon storage, but data collection requires the sensor to be flown aerially over forested areas. However, publicly available LiDAR data already exist for elevation and flood mapping and might additionally be useful to estimate forest carbon. We found that free LiDAR data could adequately estimate forest parameters important for the estimation of carbon storage and sequestration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
