HUMAN AND NATURAL SYSTEM INTERACTIONS: MODELING BIOGEOSOCIOCHEMISTRY FOR THE NEW YORK CITY CLEAN SOIL BANK

Human systems are constantly changing Earth’s lithosphere, atmosphere, hydrosphere and biosphere. These systemic linkages create the need to understand biogeochemical systems in a social context -- calling for a study of biogeosociochemistry. Quantifying such changes is a topic of much interest, and new models are being developed to understand these multiscalar interactions. While creating models is important for assessing current processes and predicting future outcomes, modeling can also be used for designing applied experiments that promote sustainable human and natural system dynamics. Here we present a case study of the biogeosociochemical issue of soil contamination in New York City (NYC). The NYC Clean Soil Bank (CSB) has been piloted as a method for mitigating soil contaminant exposure using pristine glacial sediments and locally produced compost as manufactured topsoil. In order for this program to work to its fullest potential, diverse stakeholder models are in the process of being created. This collaborative research endeavor draws upon the expertise of scientists, waste managers, greening organizations, numerous city agencies, and community members. Together, individuals and organizations are collaborating on research and materials management to address urgent issues that include minimizing waste, supporting green infrastructure, promoting urban agriculture and food justice, increasing scientific education and literacy, and minimizing exposure to harmful contaminants. The NYC CSB seeks to be an example of a scientific and public partnership that not only builds on knowledge of human and natural system interactions but also seeks to cultivate such exchanges towards sustainable ends.
