ClearQuantification and Evaluation of Grey Water Footprint in Yantai
Researchers quantified grey water footprint — the freshwater volume needed to dilute pollutants to safe levels — in Yantai, China from 2014 to 2019, finding agricultural runoff was the dominant contributor and that overall footprint declined by 2019 following pollution control efforts.
Response of Matching Degree between Precipitation and Maize Water Requirement to Climate Change in China
This study examined how climate change is altering the matching between precipitation timing and maize water requirements across China's monsoon region. Changes in intra-annual precipitation distribution and extreme weather frequency were found to affect crop water availability, with significant implications for food security.
Energy budget and carbon footprint in a wheat and maize system under ridge furrow strategy in dry semi humid areas
This agricultural study compared the energy use and carbon footprint of wheat-maize farming systems using different irrigation and planting strategies in semi-arid China. The research has no direct relevance to microplastic research but informs sustainable farming practices that reduce overall environmental impact.
The role of grey water footprint in urban wastewater management: from pollution to reuse
This study evaluated grey water footprint as a qualitative indicator of wastewater impact using eight years of real data from a municipal treatment plant and its receiving water body, demonstrating its utility for tracking wastewater management effectiveness over time.
A Methodology for Industrial Water Footprint Assessment Using Energy-Water-Carbon Nexus
Researchers developed a methodology using the energy-water-carbon nexus to assess industrial water footprints, applying it to Irish milk and beer production facilities to quantify the carbon emissions associated with industrial water consumption and treatment.
Urbanization and the Emerging Water Crisis: Identifying Water Scarcity and Environmental Risk with Multiple Applications in Urban Agglomerations in Western China
Researchers developed a comprehensive index system to evaluate water scarcity and environmental risk across three major urban regions in Western China. They found that rapid urbanization has significantly worsened water resource shortages and ecological vulnerability in these areas. The study provides a framework for understanding how urban growth intensifies water stress and suggests approaches for sustainable water resource management.
Effects of Mulching on Maize Yield and Evapotranspiration in the Heihe River Basin, Northwest China
This study examined how plastic film mulching affects maize yield and water use in northwest China's Heihe River Basin, finding that mulching increases yields and reduces evaporation. However, widespread plastic mulch use is also a major source of microplastic pollution in agricultural soils.
Identifying the Influencing Factors of Plastic Film Mulching on Improving the Yield and Water Use Efficiency of Potato in the Northwest China
This meta-analysis found that plastic film mulching increased potato yield by 25-30% and improved water use efficiency in water-scarce Northwest China. The benefits varied by precipitation level, fertilizer application, and mulching method, providing guidance for optimizing this widely used agricultural practice.
Distinct microplastic distributions in soils of different land-use types: A case study of Chinese farmlands
Microplastic distribution across six types of farmland land use was surveyed from soils in five Chinese provinces to determine how agricultural practices shape soil microplastic contamination. The study found that microplastic abundance varied significantly by land-use type, with plastic mulch film use and irrigation practices as key contributing factors.
Measurement and temporal and spatial characteristics of agricultural eco-efficiency under climate change: a case study of Anhui, China
Researchers applied super-efficient DEA-SBM analysis to measure agricultural eco-efficiency across Anhui Province, China, quantifying non-point source pollution from livestock breeding and chemical fertilizers. They found that eco-efficiency followed an 'inverted N' trend over time and exhibited spatial agglomeration patterns, with significant north-south regional differences driven by climate change and the 'Matthew effect.'
From drainage to resource: a practice approach to reuse greywater for household irrigation purposes
This study reviewed practical approaches to reusing household greywater for irrigation purposes as a strategy for addressing freshwater scarcity. The research highlights that while treated greywater can reduce potable water consumption, concerns remain about contaminants including microplastics that may be present in greywater streams.
Effects of Conservation Tillage on Agricultural Green Total Factor Productivity in Black Soil Region: Evidence from Heilongjiang Province, China
This study evaluated the effects of conservation tillage practices on agricultural green total factor productivity, finding that reduced tillage improves environmental efficiency metrics but requires management adjustments to maintain yields.
Effects of Human Activities on Evapotranspiration and Its Components in Arid Areas
Researchers analyzed evapotranspiration changes in arid southern Xinjiang, China from 1982 to 2015, finding that human activities such as land-use conversion significantly altered regional water cycling patterns and the balance between plant transpiration and soil evaporation.
Zoning management for agricultural non-point source pollution: a national-scale perspective in China
This national-scale Chinese study developed a zoning management framework for agricultural non-point source pollution, integrating ecological sensitivity, pollution load, and agricultural structure to propose differentiated management strategies for reducing water contamination from farming.
Optimal Allocation of Water Resources Considering Virtual Water Trade: A Case Study of the Yellow River
This study optimizes water resource allocation across the Yellow River basin in China by integrating both physical and virtual water flows. The study is focused on water resource management and is not directly related to microplastic research.
Enhancing carbon restoration and ecosystem resilience in global drylands via water-to-carbon biotransformation strategies
Researchers synthesized thousands of experiments on dryland farming and found that combining crop diversification, efficient irrigation, soil mulching, and soil health practices can significantly restore carbon to depleted soils while improving water use efficiency. The study argues these strategies are practical pathways for combating climate change and food insecurity in the world's most water-stressed regions.
[Characterization， Sources and Risk Assessment of Microplastic Pollution in Surface Water and Groundwater of the Hetao Irrigation Area].
This study characterized microplastic pollution in surface water and groundwater of the Hetao Irrigation Area in China, a region with over 30 years of agricultural film use. MPs were detected across drainage channels and groundwater wells, with sources linked to plastic film degradation and irrigation practices.
Status, characteristics, and ecological risks of microplastics in farmland surface soils cultivated with different crops across mainland China
Researchers conducted a nationwide survey of microplastics in farmland soils across mainland China, covering over 30 crop types in 109 cities. They found microplastics in all sampled soils, with concentrations varying by crop type, region, and farming practices such as plastic film mulching and irrigation methods. The study provides the most comprehensive picture to date of agricultural microplastic contamination in China and identifies the key farming practices that contribute most to soil pollution.
