Abstract:
... No in‐depth studies covering litter decomposition were previously conducted on afforested postmining sites despite the importance of litter decomposition on soil formation, especially in degraded areas. We aimed to compare leaf litter decomposition rates of 14 tree species growing in mixed stands on a postmining spoil heap, and to compare their decay rates with those obtained in pure stands of tre ...

Abstract:
... Soil nitrogen (N) accumulation enhances carbon (C) sequestration and subsequently the restoration of degraded ecosystems, but the changes in soil N properties after vegetation restoration in such ecosystems are poorly understood. We collected data from 358 fixed points in the karst catchment in China to determine the trends, magnitude, and mechanisms of soil N sequestration after 10 years of reveg ...

Abstract:
... Following the 2015 ‘Paris Agreement’ that seeks to contain global mean temperature increase (GMTI) to well below 2°C and more ambitiously within 1.5°C, recent studies have begun assessing the response of various sectors to these levels of warming. Most studies have so far concentrated on temperature‐sensitive sectors. Given the links between a warmer atmosphere and rainfall intensity, there is als ...

Abstract:
... The ever‐increasing and unprecedented impacts of human activities on natural landscapes are dramatically altering the heterogeneity of habitats and biodiversity. We developed a holistic resilience‐based framework to identify the early warning points of climate‐gradient landscape connectivity; the results offer the first map capable of providing information about landscape connectivity in the coast ...

Abstract:
... This study proposed an apparatus for measuring the sediment transport capacity, which is an important parameter for rill erosion prediction and modeling. Laboratory experiments were conducted to measure the sediment transport capacity of partially thawed black soil slope under different hydraulic conditions and thawed depths (five slope gradients of 5°, 10°, 15°, 20°, and 25°; three flow discharge ...

Abstract:
... Rainfall erosivity impacts all stages of hillslope erosion processes and is an important factor (the ‘R factor’) in the Revised Universal Soil Loss Equation. It is estimated as the average annual value of the sum of all erosive events (EI₃₀) over a period of many years. For each storm event, the EI₃₀ value is the product of storm energy, E in MJ ha⁻¹, and peak 30‐min rainfall intensity (I₃₀, mm hr ...

Abstract:
... Grazing is the primary land‐use activity on the Tibetan Plateau and can affect soil microbes and their function through aboveground vegetation removal, animal trampling, and manure deposition. Two distinct grazing systems (i.e., winter grazing [WG] and annual grazing [AG]) dominate on the Tibetan Plateau, but their effects on soil microbes have rarely been assessed. Taking advantage of a 5‐year fi ...

Abstract:
... There is an ongoing global debate on soil degradation, its magnitude and agro‐environmental impact, where long‐term experimentation provides quantitative criteria for its capacity for restauration with rational use and management. In this context, research in the last 30 years has confirmed that the resilience of Red Ferralitic soils in the karst regions of western Cuba is a multifactorial process ...

Abstract:
... Shrub encroachment in semi‐arid savannas is induced by interacting effects of climate, fire suppression, and unsustainable livestock farming; it carries a severe risk of land degradation and strongly influences natural communities that provide key ecosystem functions. However, species‐specific effects of shrub cover on many animal groups that act as indicators of degradation remain largely unknown ...

Subject:
best management practices; carbon sequestration; climate change; cropland; grasslands; land degradation; soil; soil organic carbon
Abstract:
... Reported potentials for sequestration of carbon in soils of agricultural lands are overly optimistic because they assume that all degraded cropland and grassland can be subjected to best management practices. Two approaches for estimating this potential are presented. Method 1 (M1) considers literature‐derived best estimates for annual soil organic carbon (SOC) gains (Mg C ha⁻¹) by bioclimatic zon ...
