Significance Achieving global environmental sustainability and food security is among the world’s biggest challenges. International trade plays an important role in security. It widely believed that importing countries benefit environmentally from international at cost of exporting countries. Contrary to conventional wisdom, our study reveals a major problem The unexpected findings suggest need reevaluate consequences all through discussions regarding responsibilities consumers producers....

International food trade has become a key driving force of agricultural land-use changes in trading countries, which influenced production and the global environment. Researchers have studied related environmental issues across multi-trading countries together, but most studies rely on statistic data without spatial attributes. However, are spatially heterogeneous. Uncovering attributes can reveal more critical information that is scientific significance policy implications for enhancing...

Whether China can achieve the United Nations’ Sustainable Development Goals (SDGs) largely depends on ability of main food-producing areas to cope with multiple land use change challenges. Despite fact that Yangtze River basin is one key regions for China’s food security, spatiotemporal dynamics cropland abandonment and recultivation remain unexplored in this region. The present study assesses evolution agricultural system within between 2000 2020 by mapping using MODIS time series cover...

Scientifically revealing the spatiotemporal patterns of cultivated land quality (CLQ) is crucial for increasing food production and achieving United Nations Sustainable Development Goal (SDG) 2: Zero Hunger. Although studies on evaluation CLQ have been conducted, an effective system that suitable macro-regional scale has not yet developed. In this study, we first defined from four aspects: soil fertility, natural conditions, construction level, productivity. Then, eight indicators were...

The structural alterations in the constituent materials of nanocomposites such as graphene typically induce changes their properties including mechanical, electrical, and optical properties. Therefore, by altering preparation conditions investigating responsiveness to basic biomolecules (such proteins), it is possible explore application potentials composites guide development new nanocomposite preparation. In this study, different oxide gold nanoparticles (AuNPs/GO) were obtained varying...

In the Amazon, development and paving of roads connects regions peoples, over time can form dense recursive networks, which often serve as nodes for continued development. These developed areas exhibit robust fractal structures that could potentially link their spatial patterns with deforestation processes. Fractal dimension is commonly used to describe growth trajectory such spatial-filling capacities. Focusing on a tri-national frontier region, we applied box-counting method calculate in...

Remote sensing appears as an essential approach for crop mapping, yet the interpretation of satellite imageries requires a large amount labeled data ground truth information. Traditional approaches collection are costly, inefficient and mostly one-off effort, thus up-to-date extremely scarce in existing mapping research applications. Here, we address challenge scarcity by implementing interactive iterative crowdsourcing framework. We developed platform, named FarmWatch, which helped process...

Abstract Paddy rice agriculture plays an important role in food security and has a considerable influence on natural systems. In the context of climate change, understanding nature drivers shifts northern limit paddy (NLPR) is crucial for adaptation strategies security. However, quantitative studies effect change distribution have not been well performed. Here, we mapped NLPR China using Landsat imagery from 1984 to 2013, analyzed latitudinal elevational dynamics Fishnet analysis, explored...

Social, economic, and environmental restorations are important concerns in mine rehabilitation programs. Nonetheless, limited attention has been given to the social economic evaluation of programs developing countries with fast‐growing economies large populations. To evaluate social, sustainability communities before after programs, we placed study China, which experienced large‐scale closures resulting from resource depletion. By adopting an integrative model, cube, evaluated environmental,...

In response to significant shifts in dietary and lifestyle preferences, the global demand for fruits has increased dramatically, especially apples, which are consumed worldwide. Growing apple orchards of more productive higher quality with limited land resources is way forward. Precise planting age identification yield prediction indispensable market terms sustainable supply, price regulation, management. The trees significantly determines productivity, quality, yield. Therefore, we...

Tropical forests in the Amazon are rapidly being cleared. Deforestation has produced marked and ecologically important fluctuations spatial patterns of forest areas. Morphological pattern analysis (MSPA) been introduced to quantitatively map areas into various classes, but remaining landscape – here 'non-forest' class is not evaluated well using this method as it simply clumped a single class. Spatial arrangements non-forest areas, including fragmentations occurring within along its exterior...

Leaf area index (LAI) is one of the important variables for crop growth monitoring and yield estimating. In this article, potato LAI was retrieved by several vegetation indices (VIs) spectral parameters continuum removal method (SPCRM) to provide accurate estimates. A comparison two methods retrieving precision completed. The data source computing VIs SPCRM hyperspectral reflectance life cycle, derived from cultivars, Favorite (early maturing variety) Yanshu 4 (late variety), through field...

Driven by intensive globalization and technological development, shifting from place-based research on ecosystem services to an understanding of multiple human natural interactions within the focal system, as well between adjacent distant systems, is becoming urgent necessity. An integrated framework metacoupling (socio-economic-environmental across borders) proposed address this shift. Here, I have demonstrated utility framework, which includes intracoupling, pericoupling, telecoupling, in...

International food trade plays an important role in security, but little research has been devoted to studying crop dynamics importing countries caused by trade. We studied the spatiotemporal patterns of soybean planting area China (the largest country) response imports. The results show how from 1980 2012 is dominated two temporal patterns, both which first increased, then decreased, with 8-year time lag. increasing-decreasing pattern affected increasing imports, and second driven...

In order to understand the main and interactive effects of water nitrogen on crop growth development, yield, fiber quality, water-nitrogen use efficiency mechanically harvested cotton with drip irrigation under plastic film in arid area western Inner Mongolia, a two-factorial experiment amount dosage completely randomized block design was conducted Alxa Left Banner League Mongolia. The levels were 216 mm (W1), 288 (W2) 360 (W3), dosages 127.5 kg·hm-2(N1), 195 kg·hm-2(N2) 262.5 kg·hm-2(N3)....

Spatial heterogeneity is a fundamental characteristic of all landscapes. There large collection methods on measurement accumulated in the past several decades, but most them largely depend categorical data as primary input. However, production spatially and/or temporally extensive land-cover maps can be extremely time-consuming and sometimes prohibitively expensive. Edge number closely related to spatial could identified by edge detection image processing techniques. The widely used...
