Projected changes in US rainfall erosivity [PDF]
Hydrology and Earth System Sciences, 2015 Abstract. Downscaled rainfall projections from 21 climate models from the CMIP5 (Coupled Model Intercomparison Project Phase 5) archive are used to estimate future changes in rainfall erosivity in the continental Unites States. To estimate erosivity from rainfall in the absence of sub-hourly data, we have used both daily rainfall values and the ...

Temperature and Farm Labor in Nigeria
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Rainfall erosivity over the Calabrian region [PDF]
Hydrological Sciences Journal, 1997 Abstract Following the results of a study carried out for the neighbouring Sicilian region, this paper reports a study of the applicability of the annual value, Faj, of the Arnouldus index to represent the erosion risk in Calabrian region. Firstly, By using 214 values of the mean annual value of the erosivity index, FF, and a Kriging interpolation ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The suboptimal efficiency of current biomass conversion processes necessitates the optimization of biochar production methodologies to enhance desired biochar characteristics. In this study, an investigation was conducted to determine the optimal air inlet configuration within a top‐lit updraft gasifier system for enhancing biochar properties ...

Influence of the rainfall measurement interval on the erosivity determinations in the Mediterranean area [PDF]
, 2006 The single-storm erosion index, EI, of the USLE and RUSLE models may vary appreciably with the rainfall measurement interval, Dt. However, the effect of Dt on EI has not been investigated in the Mediterranean area.
