Dry‐stone wall terrace monitoring and modelling
10.1002/ldr.2926 2018-04-17 Dry‐stone wall agricultural terraces are widespread all over the world and represent an effective retaining structure for farming purposes. However, dry‐stone walls can be subjected to degradation and damages, with complex and expensive maintenance. Such high... |

An estimation of the extent of cropland abandonment in mountainous regions of China
10.1002/ldr.2924 2018-04-16 With the wages for migrant workers increasing dramatically in China since 2003, the size of the agricultural labour forces has been shrinking rapidly. Intensively substituting agricultural machinery for the shrinking farm labour force is hardly possible for c... |

Effect of stand origin and slope position on infiltration pattern and preferential flow on a Loess hillslope
10.1002/ldr.2928 2018-04-02 Preferential flow is expected to provide an important pathway to replenish soil water at deep soil layers in arid or semiarid areas; however, few studies have addressed this topic, especially in semiarid Loess hillslopes. This study aimed to quantify the effe... |

Structural heterogeneity of vegetation fire ash
10.1002/ldr.2922 2018-04-02 Any wildfire generates ash, the solid residue derived from burning biomass. Vegetation fire ash consists of charred organic material, charcoal, and inorganic mineral substances. Recent studies identified ash deposits as a dual system: soil and ash strata. The... |

Influence of different sewage sludges and composts on growth, yield, and trace elements accumulation in rice and wheat
10.1002/ldr.2925 2018-03-30 The use of sewage sludge (SS) and solid waste composts in agriculture is considered as one of the best disposal options. In this study, impact of different composts and SS was evaluated on the soil quality, growth, and yield performance of rice and wheat crop... |

The role of rapid glacier retreat and landscape transformation in controlling the post‐Little Ice Age evolution of paraglacial coasts in central Spitsbergen (Billefjorden, Svalbard)
10.1002/ldr.2923 2018-03-30 In Svalbard, the rapid glacier retreat observed since the end of the Little Ice Age (LIA) has transformed the geomorphology and sediment budgets of glacial forelands, river valleys, and slope systems. To date, relatively little information exists regarding th... |

The influence of trees, shrubs, and grasses on microclimate, soil carbon, nitrogen, and CO2 efflux: Potential implications of shrub encroachment for Kalahari rangelands
10.1002/ldr.2918 2018-03-30 Shrub encroachment is a well‐documented phenomenon affecting many of the world's drylands. The alteration of vegetation structure and species composition can lead to changes in local microclimate and soil properties which in turn affect carbon cycling. The ob... |

To dam, or not to dam? Abolishment of further flooding impedes the natural revegetation processes after long‐term fluvial deposition of copper tailings
10.1002/ldr.2921 2018-03-24 Long‐term potentials and constraints of nature to spontaneously recover after severe degradation by toxic mine waste, and general principles of mutual modifications of spontaneous vegetation and soils during this process, have remained widely unknown. This st... |

Carbon balance as affected by biosolid application in reforestations
10.1002/ldr.2897 2018-03-24 Soils of Mediterranean drylands are characterized by a low fertility and organic matter content because of past land use and disturbances regime. The restoration of these degraded lands faces at the same time problems related to water scarcity and the unpredi... |
