Intensifying adoption of soil mitigation and rehabilitation measures is thus needed urgently in these ASALs, but scaling up these measures depends on scientific evidence of their contributions to key components of sustainable intensification such as soil organic ...[Show full abstract] is characterized by an arid climate and intensive agricultural utilization on loess soil, enhancing gully erosion and the formation of gullied …What Is a Semi-Arid Climate? Regions with semi-arid climates represent the second driest climates in the world after deserts, known for their dry, arid climates.

Abstract. Along with the global climate change, gully erosion, flood and drought jointly restrict the sustainable development of arid rangeland in Central Asia. Rainwater harvesting (RWH) system in gully is a flexible practice that alleviate complex environmental problems.A drier climate in the semi-arid zone is thus expected to foster rill and gully development (e.g., Valentin, 2004). Under cold conditions, global warming is expected to increase the frequency of freeze-thaw cycles exacerbating the risk of gullying as shown in southern Saskatchewan, Canada, ( Archibold et al., 2003 ) and in southern Norway ...However, under the current arid climate, an increase in the erosive processes removing part of the late Pleistocene sediments has been observed in the region. ... An early version of the manuscript was presented in Gully erosion under global change Y. Li, J. Poesen and C. Valentin (Editors): Sichuan Science and Technology Press, Chengdu, China ...Introduction. Gullies and gully erosion are major problems worldwide, particularly in arid and semi-arid environments where vegetation can be relatively scarce and therefore ineffective for protecting the soil surface from high-intensity rainfall and overland flow of water (Kompani-Zare et al., 2011; Sankey and Draut, 2014).Gully erosion destroys agricultural and domestic grazing land in many countries, especially those with arid and semi-arid climates and easily eroded rocks and soils. It also generates large amounts of sediment that can adversely impact downstream river channels. The main objective of this research is to accurately detect and predict areas prone to gully erosion. In this paper, we couple hybrid ...Although regional climates throughout much of the world appear to have become more arid in late Cenozoic time, sedimentation rates, and therefore presumably erosion rates, have increased. For sustained erosion of elevated terrain, at least where glaciers are not the major erosive agent, rivers must incise. Therefore bed-load transport by rivers should be a rate-limiting process in erosion ...This article reviews previous investigations into gully and badland research and discusses processes and definitions in the context of existing research in southeast Spain. ...

Intense gully erosion is common land degradation scenario in semi-arid climate, plateau, and hillslopes areas due to the integrated impacts of variety of factors, like land use, topography, forest cover, and climate (Gayen et al. 2019).During the monitoring time interval (1990–2001), the linear gully retreat in the study area ranged between 12.3 and 250 m an average rate of 1.12–22.7 m year−1 for each gully head.

Soil water content is a key limiting factor for vegetation growth in the semi-arid area of Chinese Loess Plateau and precipitation is the main source of soil water content in this area. To further understand the impact of vegetation types and environmental factors such as precipitation on soil water content, we continuously monitored the seasonal dynamics in soil water content in four plots ...Due to climatic change and land use/cover changes, terrestrial ET process has been noticeably shifted on multiple spatiotemporal scales (Douville et al., 2013), which influences regional water cycle, vegetation growth, and feedback on the climate change, especially in arid and semiarid regions (Fisher et al., 2011).Even in the less arid regions of mediterranean climates, periodic streams are often distinguished with special names, such as fiumare in Italy and Sicily (Walther, ...

Integration of the disconnected, eroding reaches into a continuous ...The 100th meridian west (solid line) has long been considered the divide between the relatively moist eastern United States, and the more arid West. Climate change may already have started shifting the divide eastward (dotted line).
