Soil and organic carbon losses from varying land uses: a global meta‐analysis

Soil (SL) and organic carbon losses (SOC_L) have increased with human population and climate change linked extreme events. While SL and SOC_L are clearly associated with surface run‐off, the impact of land use is still not well understood. This article elucidates the effects of land use, surface cover, and other environmental factors on SL and SOC_L using data from 55 published studies. The overall SL (12.34 ± 2.25 Mg ha^?1 year^?1) and SOC_L (21.80 ± 0.91 g C m^?2 year^?1) suggests substantial losses of the fertile topsoil globally. Grasslands (4.19 ± 1.22 Mg ha^?1 year^?1) had 77%, 66%, and 41% lower SL than orchards, croplands, and forests, respectively, which is attributable to higher soil organic matter and surface cover. Croplands had the highest SOC_L at 22.78 ± 2.22 g C m^?2 year^?1. Natural vegetation had 98% and 70% lower run‐off and SL than did plant residue mulched plots, indicating its great potential for surface run‐off and soil erosion control. Rainfall and slope were key drivers of soil erosion, while soil surface cover, SOC, and clay content decreased. These findings improve our knowledge on soil and organic carbon losses, which is useful for fostering sustainable management of soils and natural vegetation to enhance ecosystems functionality.     

Theft and Gender in Late Medieval Bologna

This article aims to challenge the prevalent presentation and analysis of gender in studies of theft in the Middle Ages. Female thieving is usually differentiated from men's – by motivation and mode, by venue and value – and these differences are related either to women's physical inferiority or to their nurturing roles (thieving to support the domestic economy) or to inequalities of access to such elements as weapons (for robbery) or tools (for burglary). When studying theft, historians have focused on male thieving as the norm, and they have tended to differentiate thieving according to gender: women mainly commit petty theft, often for immediate consumption, and do not steal on the highways, in gangs or with weapons and violence. Men, on the other hand, operate in groups: their motivation is more diverse and they use a more varied repertoire of modus operandi, which includes highway robbery. To re‐examine these characterisations, I have taken data from three twenty‐year periods from the criminal court of the city of Bologna in northern Italy (one of the most complete series of judicial records for the period). These yield a total of over 700 prosecutions and over 1,300 accused. The focus of the analysis is on elements of differentiation, such as the numbers of individual and gang thefts, the nature of goods stolen, the use of violence, et cetera. These show that, while there was some differentiation between male and female thieving, this was mainly quantitative, and that qualitatively there were more shared features of behaviour. What are often seen to be the distinguishing features of male thieving – robbery, violence, gangs, professionals – turn out to be a small, untypical group. What is often seen to be the distinguishing features of female thieving – petty theft for immediate consumption – turns out to be equally or more true of male theft.
