Responsible innovation of nano-agrifoods: Insights and views from U.S. stakeholders

Towards realizing nano-enabled precision delivery in plants

Nanocarriers (NCs) that can precisely deliver active agents, nutrients and genetic materials into plants will make crop agriculture more resilient to climate change and sustainable. As a research field, nano-agriculture is still developing, with significant scientific and societal barriers to overcome. In this Review, we argue that lessons can be learned from mammalian nanomedicine. In particular, it may be possible to enhance efficiency and efficacy by improving our understanding of how NC properties affect their interactions with plant surfaces and biomolecules, and their ability to carry and deliver cargo to specific locations. New tools are required to rapidly assess NC-plant interactions and to explore and verify the range of viable targeting approaches in plants. Elucidating these interactions can lead to the creation of computer-generated in silico models (digital twins) to predict the impact of different NC and plant properties, biological responses, and environmental conditions on the efficiency and efficacy of nanotechnology approaches. Finally, we highlight the need for nano-agriculture researchers and social scientists to converge in order to develop sustainable, safe and socially acceptable NCs.

Central Countries' and Brazil's Contributions to Nanotechnology

Abstract:

Nanotechnology is a cornerstone of the scientific advances witnessed over the past few years. Nanotechnology applications are extensively broad, and an overview of the main trends worldwide can give an insight into the most researched areas and gaps to be covered. This document presents an overview of the trend topics of the three leading countries studying in this area, as well as Brazil for comparison. The data mining was made from the Scopus database and analyzed using the VOSviewer and Voyant Tools software. More than 44.000 indexed articles published from 2010 to 2020 revealed that the countries responsible for the highest number of published articles are The United States, China, and India, while Brazil is in the fifteenth position. Thematic global networks revealed that the standing-out research topics are health science, energy, wastewater treatment, and electronics. In a temporal observation, the primary topics of research are: India (2020), which was devoted to facing SARS-COV 2; Brazil (2019), which is developing promising strategies to combat cancer; China (2018), whit research on nanomedicine and triboelectric nanogenerators; the United States (2017) and the Global tendencies (2018) are also related to the development of triboelectric nanogenerators. The collected data are available on GitHub. This study demonstrates the innovative use of data-mining technologies to gain a comprehensive understanding of nanotechnology's contributions and trends and highlights the diverse priorities of nations in this cutting-edge field.

Informing environmental health and risk priorities through local outreach and extension

Our society is currently facing an unprecedented number of environmental and societal challenges. Stakeholder and community engagement can help identify priority issues and needs at local levels. One approach to engage stakeholders and communities in the contexts of environmental, health, and societal challenges is to leverage outreach and extension programs. Within this context, and to help identify priority issues to focus subsequent research and extension programs in North Carolina (NC), a survey was conducted with extension agents to identify priority issues as they relate to environmental health and risks and related needs. Based on responses from 66 study participants that represented half of the 100 NC counties, we found that Water pollution, Flooding, Natural resources management, and Engaging stakeholders were top priority issues across all environmental health and risk topics. Participants also identified that practices of Engaging stakeholders as well as Assessing, Managing, and Communicating risks were increasingly important. Participants indicated they needed a moderate-to-significant amount of guidance across a range of areas related to assessing, managing, communicating, and making decisions regarding environmental health and risk topics, as well as engaging with local communities. Outcomes from this work can not only help inform subsequent research and outreach efforts at local scales, but this work demonstrates a simple, low-cost approach to elicit perspectives and priorities can be leveraged in other states and regions with established stakeholder and community outreach programs more broadly.

Technological Innovation and Agrifood Systems Resilience: The Potential and Perils of Three Different Strategies

The interest in technological innovation has burgeoned in recent years. Theory and research support the vital role of innovative technologies in enhancing agrifood systems resilience. In this theoretical contribution, focusing on different sets of technologies, we present three technological innovation strategies, discuss their potential for strengthening resilience, and expose some open issues that need to be addressed. Responsible technological innovation arose as a response to the growing concerns about the possible unintended impacts of mega-technological trends, like digital farming tools or nanotechnologies, on agrifood systems. Although responsibly innovating is far from easy, and despite the gaps between theoretical ideals and innovation praxis, responsible technological innovation is a promising development since it can prevent counterintuitive effects of technologies on resilience. On the other hand, poly-innovation emerged as a social practice in which internetworking technologies facilitate—and create bundles with—organizational, social, and business innovation. In that strategy, technology represents a mediator of resilience-enhancing social behavior. However, by promoting the uberization of agrifood systems, poly-innovation is associated with various uncertainties. Finally, micro-innovation refers to the incremental adaptations of existing technologies or the development of new ones through bricolage and tinkering. The commercialization of such innovations through open design can increase the resilience of small-scale farming, especially in low-income countries. Nonetheless, the lack of financial resources, technical assistance, and institutional support hamper the full exploitation of micro-innovation.
