“…This effect can be observed in AC1 and OG, which increased the clay content with respect to AC2 and V. By contrast, stored SOC was higher in the subsoil (Bt and Bt/C horizons) in AC1 and AC2, which may be due to the translocation of C in the form of dissolved organic C, soil fauna activity, and/or the effects of deep-rooting crops (Shrestha et al, 2004). On the other hand, Muñoz-Rojas et al (2012a) found an increase of SOC for LV (14 %) after conversion from arable land to permanent crops in Andalusia (southern Spain) between 1956 and 2007, caused by the limited effect that agricultural management in permanent crops has on SOC sequestration . Moreover, Vallejo et al (2003) indicates that the SOC stock is greater in crop pastures, which is an effect that has also been shown by Nair et al (2009).…”

Abstract. The agricultural Mediterranean areas are dedicated to arable crops (AC), but in the last decades, a significant number of AC has led to a land use change (LUC) to olive grove (OG) and vineyards (V). A field study was conducted to determine the long-term effects (46 years) of LUC (AC by OG and V) and to determine soil organic carbon (SOC), total nitrogen (TN), C : N ratio and their stratification across the soil entire profile, in Montilla-Moriles denomination of origin (D.O.), in Calcic-Chromic Luvisols (LVcc/cr), an area under semiarid Mediterranean conditions. The experimental design consisted of studying the LUC on one farm between 1965 and 2011. Originally, only AC was farmed in 1965, but OG and V were farmed up to now (2011). This LUC principally affected the horizon thickness, texture, bulk density, pH, organic matter, organic carbon, total nitrogen and C : N ratio. The LUC had a negative impact in the soil, affecting the SOC and TN stocks. The conversion from AC to V and OG involved the loss of the SOC stock (52.7 % and 64.9 % to V and OG respectively) and the loss of the TN stock (42.6% and 38.1 % to V and OG respectively). With respect to the stratification ratios (SRs), the effects were opposite; 46 years after LUC increased the SRs (in V and OG) of SOC, TN and C : N ratio.

“…Climate change has recently been one of the most complex challenges that has affected all the countries in the world (The World Bank, 2010). Among others factors, such as emissions of CO 2 (Muñoz-Rojas et al, 2012) and alterations in the global nitrogen cycle (Wu et al, 2013;Yu et al, 2012), LUCC is understood as one of the most important. LUCC and specially ALC are recognized as an unavoidable phenomenon during economic development and population growth (Haque et al, 2008;Tan et al, 2009; J. J.…”

Agricultural Land Conversion (ALC) has been introduced as one of the most important factors affecting ecosystem. This type of conversion has led to several challenges in agricultural development and human life. Monitoring ALC plays a crucial role when dealing with such challenges. The main objective of this study was to monitor the trend of ALC in the Qazvin province located in Northwest Iran from 1990 to 2010 using remote sensing data. The results showed that 44,845 ha of agricultural lands (3.03% of the total agricultural lands of the province) were converted to non-agricultural lands, of which, 32,033 and 10,243 ha (2.16% and 0.69% of total agricultural lands of the province), were respectively transformed to saline lands and urban areas and infrastructures. Our projection for 2030 shows that among other uses, the conversion of agricultural lands to the saline lands and urban areas and infrastructures will stay most likely. However, the conversion probability for irrigated and orchard lands to urban areas and infrastructures will be more than the saline lands while the conversion probability for dry and rangelands to the saline lands will be more than urban areas and infrastructures.

Abstract. The establishment of grasslands on abandoned cropland has been proposed as an effective method to mitigate climate change. In this study, five cultivated grasslands (three leguminous species and two gramineous species), one abandoned cropland, and one natural grassland were studied to examine how soil organic carbon (SOC) sequestration rate and sequestration efficiency change in a semi-arid area in China. Our results showed that leguminous grasslands had greater total biomass (above-and belowground biomass), SOC storage, SOC sequestration rate, and efficiency than gramineous grasslands, abandoned cropland, and natural grassland during the experimental period. The largest soil carbon (C) accumulation in leguminous grassland was mainly attributed to the capacity to incorporate C and the higher biomass production. Leguminous grasslands accumulated more SOC than gramineous grasslands by 0.64 Mg C ha −1 yr −1 . The average SOC sequestration efficiency in leguminous grassland (1.00) was about 2 times greater than gramineous grassland (0.34). The results indicate that cultivated leguminous grassland sequestered more SOC with higher SOC sequestration efficiency than cultivated gramineous grassland in arid and semi-arid areas. Our results provide a reference for ecological management in arid and semi-arid areas.
