  • Rainfall changes and rainfall erosivity increase in the Algarve (Portugal)
  • statistically confirmed by parametric and nonparamertric procedures. Rainfall erosivity and land degradation are related to rainfall regime. The Algarve's rainfall erosivity increase (+17%) was more pronounced than annual and seasonal rainfall changes.
  • There is evidence that, between hydrological years 1931/2 and 1990/1, rainfall changed in the Algarve. There was an annual rainfall increase (+9%) and a (7%) increase in rainfall during the rainy period (October to February). Both trends were
