Global products of remote sensing Normalized Difference Vegetation Index (NDVI) are
critical to assessing the vegetation dynamic and its impacts and feedbacks on climate …

Droughts are among the most complex and devastating natural hazards globally. High-
resolution datasets of drought metrics are essential for monitoring and quantifying the …

Precipitation is the most important driver of the hydrological cycle but is challenging to
estimate over large scales from satellites and models. Here, we assessed the performance …

Systematic biases and coarse resolutions are major limitations of current precipitation
datasets. Many deep learning (DL)-based studies have been conducted for precipitation …

There have been numerous drought propagation studies in data-rich countries, but not much
has been done for data-poor regions (such as the Horn of Africa, HOA). In this study, we …

The relation between drought severity and drought impacts is complex and relatively
unexplored in the African continent. This study assesses the relation between reported …

Conflicts between pastoralist groups in Africa are rampant and cause numerous deaths
each year, but their intensity exhibits significant spatial and temporal variations. Under what …

Drought indices are hard to balance in terms of versatility (effectiveness for multiple types of
drought), flexibility of timescales, and inclusivity (to what extent they include all physical …

Climate change is expected to increase the frequency of severe droughts. As water scarcity
can destroy vital resources such as crops and livestock, droughts pose major challenges to …

Ethiopia's flagship 'Productive Safety Net Programme'(PSNP) entered its fifth phase of
implementation in 2021. After more than fifteen years, the Government reoriented the …
