ABSTRACF: Bench terracing's effect on erosion, soil characteristics, crop yields, and cropping area and socioeconomic factors that affect farmers views and use of bench terraces were evaluated in the Kerinci uplands of Sumatra , Indonesia. Bench terraces reduced soil loss 70% (P<0.05) on enclosed runoff plots in comparison to unterraced fields under the same cropping pattern. Erosion under benc...

The Vale do Forno archaeological sites (Alpiarça, central Portugal) document the earliest human occupation in the Lower Tejo River, well established in geomorphological and environmental terms, within the Middle Pleistocene. In a staircase of six fluvial terraces, the Palaeolithic sites were found on the T4 terrace (þ24 m, above river bed) which is made of a basal Lower Gravels unit (LG) and an...

It is unclear where plate boundary thrusts generate giant rather than great earthquakes. Along the Himalayas, the source sizes and recurrence times of large seismic events are particularly uncertain, since no surface signatures were found for those that shook the range in the twentieth century. Here we challenge the consensus that these events remained blind and did not rupture the surface. We ...

Terraces are typical artificial landforms on the Loess Plateau, with ecological functions in water and soil conservation, agricultural production, and biodiversity. Recording the spatial distribution of terraces is the basis of monitoring their extent and understanding their ecological effects. The current terrace extraction method mainly relies on high-resolution imagery, but its accuracy is l...

Terraces are sets of trees with precisely the same likelihood or parsimony score, which can be induced by missing sequences in partitioned multi-locus phylogenetic data matrices. The potentially large set of trees on a terrace can be characterized by enumeration algorithms or consensus methods that exploit the pattern of partial taxon coverage in the data, independent of the sequence data thems...

Low fluvial terraces present azonal spatialization, encompassing several geomorphological compartments and climate zones in Brazil. Their genesis is directly related to river dynamics. When influenced by allogenic forces, such as Holocene pulses, it results channel incision posterior abandonment of the floodplain. Relatively plain landforms at different altimetric levels identified between curr...
