  • Land use/cover changes and vulnerability to flooding in the Harts catchment, South Africa
  • Geographical information system ; Inundation ; Land use ; Northern Cape ; Plant cover ; Remote sensing ; South Africa ; Statistical analysis ; Vulnerability ; Watershed
  • The purpose of this study is to determine the hydrological impacts of land use/land cover change in the Harts catchment from 1990 to 2010 using an integration of remote sensing, GIS and statistical methods. The modifications of natural vegetation
  • cover have led to modified runoff production and consequently to changing flow regimes in the Harts catchment. The coupling of surface observations, remote sensing and statistical analysis demonstrated the impacts of changes in land use/land cover

  • Land-cover changes of national nature reserves in China
  • Biodiversity ; China ; Ecosystem ; Habitat ; Index ; Nature conservation ; Nature reserve ; Plant cover
  • In this paper, 180 National Nature Reserves (NNRs) are selected. In terms of the ecosystem characteristics and their major protected object, all selected NNRs are classified into 7 types. A Positive and Negative Change Index of Land-cover (PNCIL
  • ) was developed to analyze the land-cover change of each NNRs type from the late 1980s to 2005. The results show that the land-cover of all selected NNRs types have degradated to a certain degree except the forest ecosystem reserves with a decreasing rate
  • , but the rate of degradation alleviated gradually. The landscape pattern of land-cover in the core zones was more stable than that in the buffer zones and the experimental zones. Furthermore, the ecological diversity and patch connectivity of land-cover
  • in selected NNRs increased generally. In short, the land-cover of 180 selected NNRs in China had a beneficial change trend after NNRs established, especially between 1995 and 2005.

  • Soil erosion and surface runoff on different vegetation covers and slope gradients : A field experiment in Southern Shaanxi Province, China
  • Agricultural land use ; China ; Deforestation ; Experiment plot ; Human impact ; Plant cover ; Shaanxi ; Slope gradient ; Soil erosion ; Soil properties ; Water erosion
  • A field experiment in the Shangnan County using small erosion plots was carried out to determine and compare the soil loss and surface runoff from 5 vegetation covers and 3 levels of slope gradient. The 5 vegetation covers embraced the most frequent
  • , and forestlands including low and high forests (Chinese cork-oak coppices and pine plantations, respectively). The change in the runoff among the vegetation covers and slope gradients was high but not as significantly pronounced as for the change in the soil loss
  • . Results showed that the slope gradient has an impact on the runoff and soil loss. In addition, results exhibited that the rate of erosion is substantially affected by changes in vegetation cover.

  • Quantifying successional land cover after clearing of tropical rainforest along frontiers in the Congo Basin
  • Congo DR ; Deforestation ; Fallow land ; Forest ; Geographical information system ; LANDSAT ; Land use ; Plant cover ; Remote sensing ; Scenario ; Thematic Mapper ; Tropical rain forest
  • The aim of this study was to identify these successional land-cover types and quantify their areal proportions in regions deforested during the past 37 years around the city of Kisangani, D.R. Congo. The fallow vegetation continuum was categorized
  • in different stages, adapted from existing classifications. Ground-truth points describing the present-day vegetation were obtained during a field campaign and used for supervised and validated land-cover classification of these categories, using the Landsat
  • image of 2012. Areal proportions of successional land-cover types were then derived from the resulting land-cover map. The second aim of this study was to relate these areal proportions to time since deforestation, which is expected to influence fallow

  • The AA. examined the effectiveness of 2 cover crops for improving soil physical properties and reducing erosion in a vineyard located in the Henares River basin southeast of Madrid, Spain. They assessed erosion from 3 replicate plots of 2 m2 each
  • with 3 treatments that comprised : traditional tillage, permanent cover of Brachypodium distachyon and spring-mown crop of Secale cereale. The results reinforce the notion that there are considerable benefits of using cover crops in rainfed vineyards

  • Perceptions of land cover changes in four borderline areas of Prekmurje were determined by a set of historical maps with the goal of calculating changes and analysing stability of studied areas, both from land cover perspective. Map analysis
  • was based on stability mapping and proportionating land cover categories, using time series cartography. Studied region seems stable, although over centuries inhabitants withdrew slightly from natural and political borders. As windows in the environmental

  • . They compare the effects of different soil moisture inputs of 5 vegetation types (crop>grass>subshrub>tree>shrub). The different land cover types clearly influenced the water infiltration and water input amounts in the re-vegetated area.

  • The AA. examined the effects of mound-forming shrubs and annual plants on sediment dispersal at small spatial scales in the semi-arid shrubland of the northern Negev Desert of Israel. They conducted a field experiment to test the displacement
  • of dyed sediment by wind, runoff and rain splash in 5 × 5 cm areas on shrub-mounds, placed under the canopy and on mound margins, and on the biological soil crust-covered intershrub space. As experimental treatments, they used artificial rain covers
  • and removal of annuals and their litter. It is showed that : most sediment displacement was caused by rainsplash; overhead cover by shrub canopy had the largest reducing effect on sediment loss; Removal of low annual herbs and litter increased sediment loss
  • in all locations; A combination of shrub, annual plants and litter reduces erosion most efficiently; Sediment loss by wind in the dry season was very small, in spite of strong winds.

  • To identify relevant remotely derived environmental indicators specific to biodiversity within the Canadian boreal forest, the AA. assessed indicators of the physical environment such as seasonal snow cover, topography and vegetation production
  • that the indicators used in the cluster creation provided unique information and explained much of the variance in tree (92.6%), bird (84.07%), butterfly (61.4%) and mammal (22.6%) species richness. Spring snow cover explained the most variance in species richness
  • . The most important indicators for discriminating between the different cluster groups were seasonal greenness, a multipart measure of climate, topography and land use, and wetland cover.

  • This paper describes a study in which simulated rainfall events, conduced at the field monitoring station in Linghou, Yangling District, Shaanxi, were used to study the effects of various factors (vegetation cover, rainfall intensity, and slope
  • angle) on the soil moisture increase after rainfall and the infiltration recharge coefficient (IRC). Soils hosting 3 different plants (purple medic, PM; spring wheat, SW; and ryegrass, RS) were considered, along with bare soil (BL). These soil surfaces
  • were tested with 4 different slopes and subjected to 5 different rainfall intensities. It is showed that : Vegetation cover yields a greater soil moisture increase than do bare land; Water storage initially grows and then reduces as the rain intensity

  • to storm rainfall intensity, while SWAT was applied with the PROMES results to estimate changes to soil moisture and saturation deficit, as well as vegetation cover. The results from both models were used to generate scenarios of changes to storm intensity
  • (increasing), saturation deficit (increasing) and vegetation cover (increasing according to vegetation type). These scenarios were used as input for the MEFIDIS model to study the impacts of these changes on runoff and soil erosion across spatial scales
  • for a set of storms. The results were evaluated at 2 spatial scales, that of fields (considering both (inter-) rill and gully erosion) and that of the entire catchment; and analyzed according to the dominant land-cover types in the catchments.
