Systems modeling in public health with respect to the Sustainable Development Goals is also important to increase efficiency, improve surveillance of areas where special attention is necessary, and allocation and conservation of resources. For example, scenarios can be run through systems simulation which allow one to see the trends regarding usage of resources, such as fuel and crops, as well as monitor production of those resources. This data can be used to predict yields and costs of the resource, and to decide where it is best to allocate it. Modeling can also be used to identify areas where interventions may be needed to prevent future loss and devastation. This again allows one to further model the introduction of relevant policies and survey how they effect a broad variety of sectors. For instance, if a new or dormant disease becomes active and is spreading, public health officials can begin to instate protocols to prevent the risk of spread based on the modeling system’s output. In this scenario, the modeling system could also be used to predict economic effects of an epidemic, which helps business persons prepare for potential economic declines. Financial investment strategies can also be explored through this type of modeling, in order properly allocate funds where they are needed to achieve the SDGs. Areas of low standards of living and sparse resources could require an economic boost so that they can grow and develop sustainable practices of living. The many interwoven cause and effect relationships of the SDGs and civilization make an integrative and comprehensive system imperative to examine the results of critical political, social, environmental and economic decisions that aim to change the world.
