Agriculture is threatened by ever increasing temperatures and this trend predicted to continue for the near distant future. The negative impact of rising on agri-food systems also compounded erratic highly variable rainfall in most parts southern Africa. Minimum maximum temperatures’ variability analysis were undertaken using daily time series data derived from 23 meteorological stations spread...

In recent decades, frequent compound dry and hot events have posed a great threat to humans the ecological environment, especially in Inner Mongolia, which has arid semi-arid characteristics. this study, monthly temperature precipitation data from 115 meteorological stations Mongolia 1982 2020 were used establish standardized index (SDHI). Theil–Sen median trend analysis, Mann–Kendall test, par...

A high level of fine particulate matter (PM2.5) has become one the greatest threats to human health. Based on multi-source remote sensing data, pollutant population exposure model, accompanied by Theil–Sen Median and Mann–Kendall methods, was used analyze spatio-temporal patterns global risk PM2.5 from 2000 2016. The distribution high-risk areas have been accurately identified; variation trend ...

The distinct feature of Bhutan is its special attention to peace, prosperity and happiness for its people. This research focuses on the expenditure inequality for 2007 and 2012 using various measurements including Gini Coefficients, Theil Indices and Blinder-Oaxaca decomposition. The results show that “between” rather than “within” inequality is the major factor contributing to the overall ineq...

 La degradación de los ecosistemas se ha incrementado en las últimas décadas y prevé que el cambio climático incremente su riesgo, sobre todo áridos semiáridos. El objetivo este trabajo es la caracterización del estado terrestres territorio español peninsular Islas Baleares a través análisis temporal variable RUE (Rain Use Efficiency) durante periodo 2004-2018. Las imágenes anual han calc...

Monitoring vegetation growth and exploring the driving force behind it is very important for study of global climate change ecological environmental protection. Based on Normalized Difference Vegetation Index (NDVI) data from Moderate-Resolution Imaging Spectroradiometer (MODIS), meteorological nighttime lights 2001 to 2020, this uses Theil–Sen slope test, Mann–Kendall significance Rescaled Ran...

Reference evapotranspiration (ET0) is essential for agricultural production and crop water management. The recent climate change affecting the spatiotemporal variation of ET0 in eastern China continues to still be less understood. For this purpose, latest observed data from 77 meteorological stations Anhui province were utilized determine variations by use Penman–Monteith FAO 56 (PMF-56) model....

The Theil index is much used in economy and finance; it looks like the Shannon entropy, but pertains to event values rather than to their probabilities. Any time series can be remapped through the Theil index. Correlation coefficients can be evaluated between the new time series, thereby allowing to study their mutual statistical distance, to be contrasted to the usual correlation distance meas...

Because of evident climatic variations and significant contribution to national food production, Bangladesh is a climate extreme hotspot region examination for consequences rice (Oryza Sativa) crop production. This study intends explore the variability variables (e.g., in mean temperature, rainfall, relative humidity, sunshine duration) with yields Aus, Aman, Boro varieties) northwest Banglades...

Vegetation plays a key role in maintaining ecosystem stability, promoting biodiversity conservation, serving as windbreaks, and facilitating sand fixation deserts. Based on the Moderate Resolution Imaging Spectroradiometer Normalized Difference Index (MODIS NDVI) climate data, Theil—Sen median trend analysis combined with Mann—Kendall test partial correlation residual analyses were employed to ...
