Interested in the best research from across the field of Geoscience, with our broad scope ensuring that work published reaches the widest possible audience. Understanding the Earth's history and its future evolution is becoming ever more important as the human influence on climate and landscapes, the oceans and the atmosphere expands. Nature Geoscience is a monthly multi…

Drought management is inefficient because feedbacks between drought and people are not fully understood. In this human-influenced era, we need to rethink the concept of drought to include the human role in mitigating and enhancing drought.

The term “flash drought” is currently used in an ambiguous manner in the scientific literature. We recommend that these climate features should be identified based on how rapidly they intensify. Given the increasing use of the term “flash drought” by the media and scientific community, it is prudent to develop a consistent definition that can be used to identify these events and to…

Erosion-induced changes in the physical characteristics of the surface soil under different soil and crop management treatments were monitored over a period of two years. These studies were conducted on field runoff plots established on natural slopes of 1, 5, 10 and 15%. The soil and crop management treatments consisted of bare-fallow, maize-maize (plowed and mulched), maize-maize (plowed),…

Nutrient element losses in runoff and eroded sediments were monitored during 1972 on different slopes and under different soil and crop management treatments. The experiments were conducted on 25 × 4 m field runoff plots, established on natural slopes of 1, 5, 10 and 15%. The soil and crop management treatments consisted of bare fallow (plowed), maize-maize (plowed and mulched), maize-maize …

The applicability of various erosivity indices was tested for runoff and soil loss from plowed bare-fallow field runoff plots of 25 × 4 m established on an Alfisol with natural slopes of 1, 5, 10 and 15%. The correlation coefficients of percent runoff from individual rainstorms with various indices such as kinetic energy (E), EI30, KE > 1, rainfall amount (A), maximum intensity (Im), and AIm,…
