China is a country that significantly affected by and sensitive to global climate change. Floods are one of the major natural disasters in China, they occur with high frequency wide impact country, causing serious losses. Since 1990s, have become more frequent. has made remarkable achievements flood risk management, but problems challenges this context change urbanization still require in-depth analysis targeted adaptations. During summer 2020, southern suffered from catastrophic flooding;...
Drought events have considerable direct and indirect economic, environmental, social impacts, but few studies analyzed assessed future changes in drought disasters from a risk perspective to guide responses adaptations thoroughly. Studying the potential climate-related impacts on crop yield is therefore urgently needed. Intercomparison of three Shared Socio-economic Pathway (SSP) scenarios based risks loss China was carried out using climate models Coupled Model Project Phase 6 (CMIP6),...
As a “starting zone” and “amplifier” of global climate change, the Qinghai–Tibet Plateau is very responsive to change. The temperature rise has led directly an acceleration glacial melting in plateau various glacier avalanche disasters have frequently occurred. landslide caused by avalanches will damage surrounding environment, causing secondary disaster chain effect. Take Yarlung Zangbo River at Milin County Tibet on 17 29 October 2018 as example; formation mechanical model was proposed....
The Visible and Infra-Red Radiometer (VIRR) is an improved third-generation sensor used for Earth observation with channels ranging from visible to thermal bands carried on board the Chinese FengYun-3C satellite. An active fire detection algorithm based VIRR data has already been designed tested in different study areas worldwide. Most of previously related algorithms were developed merely focusing spatial spectral features pixels while temporal attributes these observed fires ignored. In...
As a natural disaster, drought can endanger global ecology, socio-economic systems, and sustainable development. To address sudden droughts in the future, assess disasters, propose mitigation measures, in-depth research on spatiotemporal variations driving factors of meteorological is essential. study Yellow River Basin, we calculated multi-scale Standardized Precipitation Evapotranspiration Index (SPEI), derived from monthly data recorded at weather stations 1968 to 2019. We examined...
Abstract Background The recent observational studies have unveiled the correlation between composition and dynamic alterations of gut microbiome aging; however, causal relationship remains uncertain. Aims objective this study is to investigate accelerated aging as well frailty, from a genetic perspective. Methods We obtained data on microbiome, intrinsic epigenetic age acceleration, Frailty Index published large-scale genome-wide association studies. A two-sample Mendelian randomization...
Analyzing the spatiotemporal characteristics of meteorological droughts (MD) and agricultural (AD) their propagation in different climate zones is important for effective drought management, adaptation, food security. This study takes a unique approach by comparing irrigated rainfed croplands. A comprehensive framework developed using indices, statistical analysis, trend tests, wavelet transforms. The evolution patterns, trends, correlations MD AD Xinjiang Middle-lower Yangtze Plain (MYP)...
Abstract Digital Agriculture is one of the important applications Earth. As global climate changes and food security becomes an increasingly issue, agriculture drought comes to focus attention. China a typical monsoon country as well agricultural with world's largest population. The East Asian has had tremendous impact upon production. Therefore, maize disaster risk assessment, in line requirements sustainable development agriculture, for ensuring reduction security. Meteorology, soil, land...
Drought poses a serious threat to agricultural production and food security in the context of global climate change. Few studies have explored response mechanism lag time drought meteorological from perspective cultivated land types. This paper analyzes spatiotemporal evolution patterns hysteresis relationship droughts middle lower reaches Yangtze River China. Here, Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation index products surface temperature were selected calculate...
Winter wheat cropland is one of the most important agricultural land-cover types affected by global climate and human activity. Mapping 30-m winter can provide beneficial reference information that necessary for understanding food security. To date, machine learning algorithms have become an effective tool rapid identification at regional scales. Algorithm implementation based on constructing selecting many features, which makes feature set optimization issue worthy discussion. In this...
A wavelet transform technique was used to analyze the precipitation data for nearly 60 years (1954–2012) in Yunnan Province of China. The coefficients and variance yield were calculated. results showed that, years, spring increased slightly; however, linear trend other seasonal annual precipitations a reducing trend. Seasonal had characteristics multiple time scales. Different scales different cyclic alternating patterns. Overall, next period time, seasons will be periods...
Wildfires are one of the most destructive disasters on planet. They also significantly impact land surface. Satellite data have been widely used to detect outbreak and monitor expansion fire incidents for damage assessment disaster management. Polar-orbiting satellite several decades but from geostationary satellites, which can provide observations with a high temporal resolution, received much less attention. This paper utilizes FengYun-2G, Chinese satellite, wildfires in two selected...
The cascading impact of disastrous events has become an important focus disaster research. In recent years, forest fires have occurred frequently in China, causing huge economic losses. Studying the impacts drought and fire is great significance for reducing risks. Taking Yunnan Province China as example, meteorological data point from 2005 to 2018 were collected statistically analyzed. A Bayesian network model was established, enabling prior probability conditional nodes be determined....
Droughts are one of the primary natural disasters that affect agricultural economies, as well fire hazards territories. Monitoring and researching droughts is great importance for disaster prevention reduction. The research significance investigating hysteresis to meteorological provide an important reference drought monitoring early warnings. Remote sensing indices can be employed rapid accurate at regional scales. In this paper, Moderate Resolution Imaging Spectroradiometer (MODIS)...
Typhoons are a product of air-sea interaction, which often accompanied by high winds, heavy rains, and storm surges. It is significant to master the characteristics pattern typhoon activity for warning disaster prevention mitigation. We used Kernel Density Estimation (KDE) index as hazard index; probability exceeding, or reaching, return period exceeding certain threshold was describe occurrence. The results show that overall spatial distribution hazards conforms northeast-southwest zonal...
Accurately predicting the populations with difficulties accessing drinking water because of drought and taking appropriate mitigation measures can minimize economic loss personal injury. Taking 2013 Guizhou extreme summer as an example, on basis collecting meteorological, basic geographic information, socioeconomic data, disaster effect data study area, a rapid assessment model based backpropagation (BP) neural network was constructed. Six factors were chosen for input network: average...
