The Science and Technologies for Phosphorus Sustainability (STEPS) Center is a convergence research hub for addressing the fundamental challenges associated with phosphorus sustainability. The vision of STEPS is to develop new scientific and technological solutions to regulating, recovering and reusing phosphorus that can readily be adopted by society through fundamental research conducted by a broad, highly interdisciplinary team. Key outcomes include new atomic-level knowledge of phosphorus interactions with engineered and natural materials, new understanding of phosphorus mobility at industrial, farm, and landscape scales, and prioritization of best management practices and strategies drawn from diverse stakeholder perspectives. Ultimately, STEPS will provide new scientific understanding, enabling new technologies, and transformative improvements in phosphorus sustainability.
This proposal puts forth a timely and multi-faceted approach to assess the societal implications of genetic engineering (GE) and nanotechnology used in food and agriculture (agrifoods) and identify strategies to ensure the sustainable futures of agrifood technologies according to diverse stakeholder perspectives. There are three primary objectives: 1) Assess societal implications and improve decision-making of GE- and nano-agrifood products through benefit-risk evaluations; 2) Identify strategies to ensure sustainable development and use of GE and nano-agrifoods through multi-stakeholder engagement and exchange; 3) Develop interdisciplinary education and training opportunities to better evaluate societal implications of new and novel agrifood technologies. Key project outcomes will help policy-makers and other decision-makers i) make informed decisions on GE- and nano-agrifoods, particularly in contexts of benefits and risks, ii) understand societal implications of GE- and nano-agrifoods based on stakeholder perceptions and attitudes, and iii) identify best practices for evaluating societal implications of new and novel agrifood technologies according to diverse perspectives.
A Pipeline of a Resilient Workforce that integrates Advanced Analytics to the Agriculture, Food and Energy Supply Chain
Inconsistent quality and aesthetics in agricultural crops can result in increased consumer and producer food waste, reduced industry resiliency and decreased farmers������������������ and growers������������������ profit, poor consumer satisfaction, and inefficiencies across the supply chain. Although there are opportunities to characterize and quantify sources of phenotypic variability across the agricultural supply chain - from cultural practices of growers and producers to storage and handling by distributors - the data available to allow for assessment of horticultural quality drivers are disparate and disconnected. The absence of data integration platforms that link heterogeneous datasets across the supply chain precludes the development of strategies and solutions to constrain variability in produce quality. This project������������������s central hypothesis is that multi-dimensional produce data can be securely integrated and used to optimize management practices in the field while simultaneously adding value across the entire food supply chain. We propose to develop multi-modal sensing platform along with a trust-based, data management, integration, and analytics framework for systematic organization and dynamic abstraction of heterogeneous data across the supply chain of agricultural crops. The projects short term goals are to (1) engage growers to refine research and extension priorities; (2) develop a first-of-its-kind modular imaging system that responds to grower needs by analyzing existing and novel multi-dimensional data; (3) establish the cyberinfrastructure, including analytics and blockchain, to make meaningful inference of the acquired data as related to management practices while ensuring data security; (4) deploy the sensing system at NCSU������������������s Horticultural Crops Research Station in Clinton, NC and on a large-scale system at a major commercial farm and distribution facility, and (5) extend findings to producers and regulators through NC Cooperative Extension. The proposed sensing and cyberinfrastructure platforms will be crop-agnostic and our findings will be transferable to other horticultural crops produced in NC and beyond.

Technological advancements involving gene drive applications in agriculture are proceeding rapidly (e.g., use of Drosophila suzukii or Diaphorina citri that feed on soft-skinned and citrus fruits). At the same time, there are gaps in governance systems and challenges to acquiring underlying data for risk assessments. It is also important to couple risk assessments with studies on public perceptions and acceptance, heeding past lessons learned from ag-biotechnology (1), and enhance risk assessments through informed interdisciplinary engagement (2)(3)(4)(5). Interdisciplinary exchanges may also help ensure that responsible research and innovation is realized in the case of gene drive applications in agriculture. In essence, diverse and multi-stakeholder conversations should be conducted alongside research endeavors aimed to conduct risk assessments for gene drives. This conference proposal aims to inform risk assessment research strategies for gene drive agricultural applications through interdisciplinary dialogue and exchange with diverse experts.
This application proposes a cost-effective approach to grow and expand the Research Triangle Park (RTP) chapter of SRA located in North Carolina (USA), enhance and strengthen the field of risk science, and promote risk science as a profession. These project goals will be accomplished through a series of strategic activities that leverage existing risk-based, multi-stakeholder collaborations in the RTP area along with the team������������������s professional networks and connections with international scholars in risk science. Key outcomes of the proposed work include a reinvigoration of the SRA RTP chapter that will promote SRA membership growth along with networking and professional development for risk science students, scholars, and professionals. The proposed work will be carried out in three main themes: 1. Reinvigorate the RTP chapter of SRA, 2. Enhance and strengthen risk science through networking and guest lectures, and 3. Grow and promote risk science through professional development opportunities.
This project will evaluate the social implications of and identify best practices for the responsible innovation (RI) of nanomaterials used in food and agricultural sectors. The proposed work advances the ����������������Social Implications of Food and Agricultural Technologies Program Area��������������� Program Area (Priority Code A1642). The project will achieve four objectives: (1) identify, describe, and compare exemplary cases of RI for nanomaterials used in food and agriculture (nano-agrifoods); (2) elucidate incentives and barriers for RI of nano-agrifoods; (3) capture key stakeholder pereptions and concerns regarding nano-agrifoods across the farm-to-fork spectrum and identify approaches to address concerns through practices of RI; and (4) identify lessons learned from, best practices for, and policy implications of RI relevant for other emerging food and agriculture technologies. Key project outcomes include critical information on (1) practices of RI that can help ensure sustainability of nano-agrifoods and build trust, (2) stakeholder concerns of nano-agrifoods and approaches to address them, and (3) key lessons learned from nano-agrifoods that help ensure sustainability of other novel agrifood technologies. Project outcomes will be disseminated through peer-reviewed manuscripts, a policy brief, conference presentations, and social media platforms. Overall, project findings will help product developers, policy-makers, and other stakeholders ensure RI occurs for nano-agrifood sectors with relevancy for the sustainability of other emerging food and agriculture technologies.
