Existing studies have revealed the effects of rainfall
Research gap analysis derived from 4 agriculture papers in our local library.
The gap
While existing studies have revealed the effects of rainfall intensity and slope on soil erosion, a comprehensive analysis of the interactions between different rainfall types and slope is still lacking.
Evidence profile
Sourced from the abstract and stated research gap and future-work section of the source papers, classified as general, drawn from work published between 2024 and 2026, spanning 4 journals. Those papers have been cited 8 times in total.

The study identifies a gap in the understanding of the effect of soil amendments and rainfall rate on soil runoff, drainage, and evaporation. The increasing temperature and inappropriate land management can result in high soil water evaporation and loss of topsoil.

Future research should investigate the effects of conservation agriculture on soil erosion and runoff in other regions. The use of rainfall simulators to generate standardized rain-shower on plots with standard surface area should be further explored.
