Drought vulnerability and risk assessment in India: Sensitivity analysis and comparison of aggregation techniques.

J Environ Manage 2021 Sep 8;299:113689. Epub 2021 Sep 8.

Department of Civil Engineering, Indian Institute of Technology Bombay, Powai, Mumbai, 400076, India.

Long term drought management requires proper assessment and characterization of drought hazard, vulnerability and risk. This is particularly important for an agriculture-dependent, highly-populated, developing country such as India. However, the regulation of drought vulnerability and drought risk assessment in the country is mostly region-specific and ad-hoc, considering only a limited number of vulnerability indicators.

Copula-based framework for integrated evaluation of water quality and quantity: A case study of Yihe River, China.

Sci Total Environ 2021 Sep 4;804:150075. Epub 2021 Sep 4.

Key Laboratory of Efficient Irrigation-Drainage and Agricultural Soil-Water Environment in Southern China (Ministry of Education), College of Agricultural Sciences and Engineering, Hohai University, Nanjing 210098, China.

Water quantity and quality are two key factors affecting the performance of integrated watershed management. Conventional water resources assessment of rivers often deals with water quantity and quality separately. However, how to make an objective and impartial assessment of water resources by incorporating both water quantity and quality remains unclear, especially in watersheds with significant human activity impacts and high spatiotemporal variations in flows.

New indices system for quantifying the nexus between economic-social development, natural resources consumption, and environmental pollution in China during 1978-2018.

Sci Total Environ 2021 Sep 8;804:150180. Epub 2021 Sep 8.

Department of Urban Planning and Design, Faculty of Architecture, the University of Hong Kong, Hong Kong 999077, China.

It is meaningful to study how China can maintain the sustainable utilization of natural resources and the continuous improvement of environmental conditions while ensuring the stable development of the economy and society. In this study, a new indices system was proposed for the analysis of nexus among social-economic-natural resource-environment complex systems following the DPSIR (Driving Force - Pressure - State - Impact - Respond) framework, CCD (Coupling Coordination Degree) analysis and VAR (Vector Auto-Regressive) model were applied for quantifying the synergy and trade-off of China in the nexus framework. Results showed that: (1) Although China's rapid development has caused big consumption of natural resources and increasing pollutants discharges during 1978-2018, China has not got into trouble of extreme resource depletion and ecosystem collapse.

Atraumatic Pyogenic Extensor Tenosynovitis of the Extensor Digitorum Longus.

Cureus 2021 Aug 6;13(8):e16952. Epub 2021 Aug 6.

Department of Orthopedics, Heiden Orthopedics, Park City, USA.

Pyogenic tenosynovitis occurs almost exclusively in the flexor tendons of distal extremities, more commonly in the hand/wrist than the ankle/foot. Most commonly documented in the literature of the rarer extensor pyogenic tenosynovitis are case reports in the upper extremities caused by atypical bacteria or fungi, with only two cases caused by Staphylococcus aureus. It is rare for isolated tenosynovitis to occur in the extensor tendons of the lower extremity in a patient with no known trauma, IV drug use, or significant comorbidities. Read More

First Aid for Pool Chemical Exposure: A Narrative Review.

Cureus 2021 Jul 30;13(7):e16755. Epub 2021 Jul 30.

Emergency Medicine, University of Virginia, Charlottesville, USA.

Over 4500 visits to emergency departments related to pool chemical exposures occur annually in the United States, and it is likely that many more go unreported. Injury can occur due to sensitivity to standard chemical concentrations in pools (such as with opening one's eyes underwater), accidental exposure to super-concentrated chemicals (such as malfunction of a pool chlorinator), or accidental inhalation of fumes while opening the storage container for chlorination tablets. Therefore, first aid care has the potential to significantly limit morbidity. Read More

Characterization of A4, an Almond-Derived Plant Growth-Promoting Endophyte.

Front Microbiol 2021 25;12:687971. Epub 2021 Aug 25.

Sierra Nevada Research Institute, University of California, Merced, Merced, CA, United States.

The rapidly increasing global population and anthropogenic climate change have created intense pressure on agricultural systems to produce increasingly more food under steadily challenging environmental conditions. Simultaneously, industrial agriculture is negatively affecting natural and agricultural ecosystems because of intensive irrigation and fertilization to fully utilize the potential of high-yielding cultivars. Growth-promoting microbes that increase stress tolerance and crop yield could be a useful tool for helping mitigate these problems. Read More

Shifts in biochemical and physiological responses by the inoculation of arbuscular mycorrhizal fungi in Triticum aestivum growing under drought conditions.

J Sci Food Agric 2021 Sep 12. Epub 2021 Sep 12.

Centro de Investigación en Micorrizas y Sustentabilidad Agroambiental, CIMYSA, Facultad de Ingeniería y Ciencias, Universidad de La Frontera, Temuco, Chile.

Background: A decrease in rainfall is one of the main constraints on wheat production, but the association of wheat with arbuscular mycorrhizal fungi (AMF) may be an alternative for crop production under drought conditions. Here, we used three wheat cultivars (Purple, Ilustre and Maxi Baer) inoculated with two AMF strains, one obtained from the hyperarid Atacama Desert (northern Chile; Fm) and the other obtained from southern Chile (Cc). Plants were maintained under two irrigation conditions (normal irrigation and drought), and the physiological behaviour and enzymatic and nonenzymatic antioxidant activities in the shoots were determined.

A new approach to suppress methane emissions from rice cropping systems using ethephon.

Sci Total Environ 2021 Sep 7;804:150159. Epub 2021 Sep 7.

Division of Applied Life Science (BK 21 plus program), Graduate School, Gyeongsang National University (GNU), Jinju-city 52828, South Korea; Institute of Agriculture and Life Sciences (IALS), Gyeongsang National University (GNU), Jinju-city 52828, South Korea. Electronic address:

Rice is the main staple food for more than half of the world's population. Yet, rice cultivation is subjected to criticism because of its important role in methane (CH) emissions. Although several agronomic practices such as controlled irrigation and conservation tillage have been widely adopted to mitigate CH emissions from rice cultivation, the benefits gained by these practices are highly dependent on site-specific soil and climate conditions, and often offset by yield reduction.

Do soil cadmium concentrations decline after phosphate fertiliser application is stopped: A comparison of long-term pasture trials in New Zealand?

Sci Total Environ 2021 Sep 4;804:150047. Epub 2021 Sep 4.

AgResearch, Lincoln Science Centre, Private Bag 4749, Christchurch 8140, New Zealand.

Decreasing soil cadmium (Cd) is one method of removing Cd from the food chain. Phosphorus (P) fertilisers are a major source of Cd inputs into soil. Stopping P fertiliser should theoretically decrease Cd inputs and soil Cd accumulation, but there are few field data to show if this occurs. Read More

Ecotoxicol Environ Saf 2021 Sep 8;225:112752. Epub 2021 Sep 8.

College of Natural Resources and Environment, Northwest A&F University, Yangling, Shaanxi 712100, PR China. Electronic address:

The content of Cd, Cu, Pb, Zn, Cr, Ni and As from 250 soil samples was measured in agricultural soil of Ningxia section of the Yellow River. Positive matrix factorization (PMF) was to identify the main sources of these heavy metals; Sequential Gaussian Simulation (SGS) was to identify their spatial distribution and high-risk areas; and Human Health risk (HHR) model was to measure the health risk. Results showed that the average content of Cd and As exceeds the risk screening value of "Soil Environmental Quality-Agricultural Land Soil Pollution Risk Control Standard" (GB 15618-2018), which belongs to slight-level pollution.
