The drought trend for each biome was computed for each pixel using a linear regression model in R software using the seasonal VCI images from 1998 to 2017. Our result showed that extreme drought impact on vegetation was mainly confined to the southwestern biomes (i.e. the Nama karoo and ...
In the CDS, this variable is called drought_code. From these weather-driven fuel moisture calculations, the FWI model generates fire behavior indices in terms of: • The Initial Spread Index (ISI), a measure of the rate at which a fire would spread in its early stages shortly after ...
Like many other African countries, incidence of drought is increasing in Nigeria. In this work, spatiotemporal changes in droughts under different representative concentration pathway (RCP) scenarios were assessed; considering their greatest impacts on l
Analysis of long-term meteorological data is critical for monitoring climate trends and understanding the drought situation in a given region. In this study, monthly average precipitation data from the Niğde meteorological station in Turkey covering the period 1950–2020 were used. Within the scope...
Next, the images from each year were added together to calculate the frequency of drought at a pixel level. As Gonfa [64] has outlined and as recently applied by Wassie et al. [18], areas can be categorized as high, moderate, or low-risk zones based on the probability of drought ...
However, it is still difficult to pin vegetation variances on drought because of the delay of the caused vegetation stress. To assess vegetative drought, it is important to first understand the relationship between meteorological condition and vegetation condition, and measure the vegetation responses ...
At the STEL site, the soil needed particularly dry conditions for many consecutive days to reach low water content and create drought conditions, as observed by the first sensor in 2016 and 2018 (Fig.5a). Hence, a higher AET demand was necessary to evacuate the pore water in the denser an...
In addition to the immediate direct impacts of extreme weather events, there may be indirect repercussions, such as insurance losses. During the summer of 2003, European drought conditions caused crop losses of around US$13 billion, while an additional US$1.6 billion in damage was associated with...

Again, drought conditions can reduce the availability of fresh water and can lead to diarrhoeal and other diseases due to poor hygiene22. Other studies23,24 observed that the occurrence of diarrhoeal diseases was maximum during the summer months followed by rainy or winter months over two slum ...
