Multiple pollutants from crop and livestock production in the Yangtze River: status and challenges

Multiple pollutants from crop and livestock production in the Yangtze River: status and challenges
2024-04-16
(Press-News.org)

The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin (YRB) has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten green agricultural development. To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil–plant–water system. Prof. Xinping Chen from Southwest University and his team considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and agricultural green development. It presents prospective on theory, modeling and multi-pollutant control in the YRB for Agriculture Green Development (AGD) that are of potential value for other developing regions.

The structure of the cropping system has evolved to simultaneously meet the increasing demand for both human food and animal feed. Animal manure is effectively recycled for crop use, and these waste and pollution sources become the resources in crop production. However, the safe and sustainable use of organic fertilizers for crop production is yet to be fully implemented. In addition to nutrient pollutants, the YRB faces severe water quality issues caused by the combined effects of other pollutants, including antibiotics and pesticides. These distressing discoveries emphasize the need to raise awareness about the multiple pollutants in the YRB and urge the public to take necessary measures to address these issues.

The biological, physical and chemical interactions of multiple pollutants like antibiotics, pesticides and nutrients (N and P) and their biogeochemical cycles limit global and national efforts to achieve AGD. It is essential to consider the transport mechanism of coexisting pollutants via hydrological processes, especially in mountain areas with cash crops. In addition to the toxicity of each pollutant, the complex interactions between multiple pollutants need to be more thoroughly understood to assess and manage the ecological risks of water and soil pollution effectively. The water quality modeling approach is a tool to better understand the hotspots and sources of water quality issues and to provide evidence for policymaking and policy implementation for the provision of clean water. Ecological thresholds are useful indicators for identifying pollution levels, and it serves as restoration goals for aquatic and terrestrial systems enabling the formulation of future management options. However, the ecological thresholds for multiple pollutants, other than nutrients, have yet to be set by consensus.

Reducing mineral fertilizer applications in line with efficient nutrient utilization is the key to achieving the goals of green and sustainable agriculture. Soil microorganisms drive key functions in agroecosystems, determining soil fertility, crop productivity and stress tolerance. Multi-pollutant river models will formally represent nutrient cycling processes knowledge, allowing them to reason through previously unseen tasks and use agricultural or environment-accurate language to explain their outputs. Overall, this study reflect on future directions for multi-pollutant modeling and the linking model results to policymaking. Policymakers, scientists and other stakeholders have to work together with academics and technical experts for agricultural green development in the YRB. Analyses of dietary trends and food supply should guide local agricultural development, which will determine future multi-pollutant scenarios. Climate change effects, such as an extreme rainstorm, heat waves and drought events, require the policy design to ensure the crop and livestock production are more inclusive of extreme climate events in the YRB. It is hoped that recognition of these potential risks will improve the overall level of accounting for consequences associated with multiple pollutants from crop and livestock production under policy scenarios in the YRB.

This study has been published on the Journal of Frontiers of Agricultural Science and Engineering in Volume 11, Issue 1, 2024, DOI: 10.15302/J-FASE-2023511

Unraveling the unique role of DELLA proteins in grapevine flowering: A shift in developmental fate

2024-04-16
The transition from vegetative to reproductive stages in plants involves both internal and external cues, with grapevines  (Vitis vinifera L. cv. Pixie) presenting a unique case. Research shows that a mutation in the grapevine's DELLA proteins enhances the conversion of tendrils to inflorescences, diverging from DELLA's typical role in suppressing flowering in annual plants. While DELLA proteins regulate plant growth by interacting with various genes and environmental signals, the specific mechanisms and genes targeted ...

Next-generation treatments hitch a ride into cancer cells

Next-generation treatments hitch a ride into cancer cells
2024-04-16
Osaka, Japan – Antisense oligonucleotides (ASOs) are next-generation drugs that can treat disease by blocking the transfer of harmful messages from our genes. In people with cancer, ASOs have the potential to block messages that encourage the growth and spread of the tumor. However, ASOs aren’t used for treating cancer yet. They must first get delivered inside cancer cells, but the cancer cells won’t let them in. Finding an effective ASO delivery system is a major challenge. Cancer cells have gatekeeper molecules that stop unwanted substances from entering. Although investigators have tried many ways of getting ASOs past ...

Unraveling the role of DlBGAL9 and AGL61/80 in Longan somatic embryogenesis and heat stress tolerance: A multi-omics approach

2024-04-16
A research team has unveiled 20 β-galactosidase (BGAL) genes within the longan genome, highlighting their crucial roles in embryogenic development and heat stress adaptation. Particularly, the research team spotlighted DlBGAL9, activated by transcription factors DlAGL61 and DlAGL80, as pivotal in enhancing β-galactosidase activity for cell wall thickening and stress response. These discoveries not only deepen our understanding of BGAL's function in plant development and stress mechanisms but also open pathways for agricultural innovations to improve crop resilience and productivity through genetic ...

Decoding pecan pollination: A dive into the chloroplast genome of 'Xinxuan-4' and its impact on cultivar diversity and efficiency

2024-04-16
The chloroplast (cp) is critical for various biological functions in plants, such as photosynthesis and stress responses, with its genome offering simpler analysis and sequencing due to its size and reduced homologous influence. This genome's stability and unique features have made it essential for species identification and understanding plant phylogeny. In the context of Carya illinoinensis, or pecan, a key nut crop in China, there's an observed pollination deficiency exacerbated by the timing of pollen release in cultivars like 'Pawnee'. Recent research has expanded to include the cp genomes of various C. illinoinensis cultivars, aiding ...

KD-crowd: A knowledge distillation framework for learning from crowds

KD-crowd: A knowledge distillation framework for learning from crowds
2024-04-16
Crowdsourcing efficiently delegates tasks to crowd workers for labeling, though their varying expertise can lead to errors. A key task is estimating worker expertise to infer true labels. However, the noise transition matrix-based methods for modeling worker expertise often overfit annotation noise due to oversimplification or inaccurate estimations. To solve the problems, a research team led by Shao-Yuan LI published their new research on 12 Mar 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature. The team proposed a knowledge distillation-based framework KD-Crowd, which leverages noise-model-free ...
