Combining Multiple High-Resolution Techniques to Understand Phosphorous Availability Around Rice Roots.

Environ Sci Technol 2021 Sep 23. Epub 2021 Sep 23.

State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing, Jiangsu 210023, China.

Resolving chemical/biological drivers of P behavior around lowland/flooded rice roots remains a challenge because of the heterogeneity of the plant-soil interactions, compounded by sampling and analytical constraints. High-spatial-resolution (sub-mm) visualization enables these processes to be isolated, characterized, and deciphered. Here, three advanced soil imaging systems, diffusive gradients in thin-film technique coupled with laser ablation-ICPMS (DGT-LA-ICPMS), O planar optode, and soil zymography, were integrated.

Recent progress on the heavy metals ameliorating potential of engineered nanomaterials in rice paddy: a comprehensive outlook on global food safety with nanotoxicitiy issues.

Crit Rev Food Sci Nutr 2021 Sep 23:1-15. Epub 2021 Sep 23.

State Key Laboratory of Rice Biology, Institute of Biotechnology, Zhejiang University, Hangzhou, China.

Soil contamination with toxic heavy metals (HMs) poses a serious threat to global food safety, soil ecosystem and human health. The rapid industrialization, urbanization and extensive application of agrochemicals on arable land have led to paddy soil pollution worldwide. Rice plants easily accumulate toxic HMs from contaminated agricultural soils, which ultimately accumulated in grains and enters the food chain. Read More

PncsHub: a platform for annotating and analyzing non-classically secreted proteins in Gram-positive bacteria.

Nucleic Acids Res 2021 Sep 22. Epub 2021 Sep 22.

Infection and Immunity Program, Biomedicine Discovery Institute and Department of Microbiology, Monash University, VIC 3800, Australia.

From industry to food to health, bacteria play an important role in all facets of life. Some of the most important bacteria have been purposely engineered to produce commercial quantities of antibiotics and therapeutics, and non-classical secretion systems are at the forefront of these technologies. Unlike the classical Sec or Tat pathways, non-classically secreted proteins share few common characteristics and use much more diverse secretion pathways for protein transport. Read More

The status of fertility control for rodents - recent achievements and future directions.

Integr Zool 2021 Sep 22. Epub 2021 Sep 22.

CSIRO Health and Biosecurity, Canberra, ACT, Australia.

Management of overabundant rodents at a landscape scale is complex but often required to sustainably reduce rodent abundance below damage thresholds. Current conventional techniques such as poisoning are not species specific, with some approaches becoming increasingly unacceptable to the general public. Fertility control, first proposed for vertebrate pest management over 5 decades ago, has gained public acceptance because it is perceived as a potentially more species-specific and humane approach compared with many lethal methods.

Effects of different Danish food consumption patterns on Water ScarcityFootprint.

J Environ Manage 2021 Sep 20;300:113713. Epub 2021 Sep 20.

Research Group on EcoIndustrial System Analysis, Department of Environmental Science, Aarhus University, Frederiksborgvej 399, Postboks 358, DK-4000, Roskilde, Denmark; Aarhus University Centre for Circular Bioeconomy, Denmark; European Commission, Joint Research Centre, Directorate Growth and Innovation, Circular Economy and Industrial Leadership Unit, Seville, Spain.

Food production and consumption have been recognized as a major source of environmental impacts. To ensure food security and a sustainable food system, dietary changes have been identified as one of the valuable strategies to reduce impacts on the environment while promoting human health. The vast majority of scientific literature has been focused on the effects of food consumption on climate change while neglecting to assess the degree of water scarcity impacts due to water consumption embodied in food.

Nitrogen fixing cereal: A rising hero towards meeting food security.

Plant Physiol Biochem 2021 Sep 10;167:912-920. Epub 2021 Sep 10.

ICAR - National Institute for Plant Biotechnology, Indian Agricultural Research Institute, New Delhi, 110012, India.

Nitrogen serves as one of the primary components of major biomolecules and thus extends a significant contribution to crop growth and yield. But the inability of plants to utilize freely available atmospheric N makes the whole agricultural system dependent on chemical fertilizers, which incur significant input cost to supplement required quantities of nitrogen to crops. Only bacteria and archaea have been gifted with the power of drawing free N from air to convert them into NH, which is one of the two utilizable forms of nitrogen taken up by plants. Read More

Migrants on the Move and Food (In)security: A Call for Research.

J Immigr Minor Health 2021 Sep 20. Epub 2021 Sep 20.

Instituto Nacional de Salud Pública, Cuernavaca, Mexico.

Food insecurity contributes to negative outcomes for health and wellbeing, and its impact may be exacerbated during periods of vulnerability. While food insecurity is both a driver and a consequence of migration, anecdotal evidence indicates that it is also common during migration when people are 'on the move', although its prevalence and severity during these periods are largely undocumented. Food security monitoring is critical to ensuring the universal right to food for migrants, and instruments must be designed which capture the unique challenges faced during these 'extra-ordinary' periods of mobility, including in the context of emergencies such as the COVID-19 pandemic.

The importance of animal welfare and Veterinary Services in a changing world.

Rev Sci Tech 2021 08;40(2):469-481

Animal welfare is an essential component of the future of sustainable agriculture and the United Nations Sustainable Development Goals. There is growing global recognition of the importance of animal welfare, which must always be considered as part of the decision-making around food and nutrition security. Veterinary Services, encompassing public and private veterinarians and para-veterinarians, are custodians of animal welfare and key players in future actions to improve it. Read More

Sustainable Development Goals and livestock systems.

Rev Sci Tech 2021 Aug;40(2):585-595

Within the framework of the Sustainable Development Goals (SDGs) of the United Nations, particularly those that livestock impact most significantly (SDGs 1, 2, 3, 5, 8, 12, 13, 15 and 17), this paper provides an overview of the livestock sector's impact on food system sustainability and opportunities for building solutions through sustainable livestock options that are supported by robust animal health services. The discourse is shaped by the experiences of the Global Agenda for Sustainable Livestock, a multi-stakeholder partnership which facilitates policy dialogue and action among diverse stakeholders to make livestock systems more sustainable. The Global Agenda for Sustainable Livestock adopted the aforementioned SDGs as the reference framework for its actions, which are organised under four domains (food and nutrition security, animal health and welfare, livelihoods and economic growth, and climate and natural resources).
