Land degradation and the coastal environment of Nigeria
  • Land degradation and the coastal environment of Nigeria
  • Coastal environment ; Human impact ; Land use ; Nigeria ; Oil industry ; Regional planning ; Soil degradation
  • This paper uses primary and secondary data sources to describe cases of land degradation based on the morphological units of Nigeria's shoreline. Anthropogenic influences accelerate land degradation along the coastline hence, the need
Applications of reflective remote sensing for land degradation studies in a Mediterranean environment
  • Applications of reflective remote sensing for land degradation studies in a Mediterranean environment
  • Ardèche ; France ; Modelling ; Remote sensing ; Rhône-Alpes ; Soil degradation ; Soil erosion
  • The aim of this book is to investigate the role of remote sensing in understanding and modelling land degradation processes. The research was carried out in the southern part of Ardèche province in France. Several degradation features are found
Land degradation: creation and destruction
  • Land degradation: creation and destruction
  • Environment ; Environmental degradation ; Human impact ; Man-environment relations ; Population pressure ; Resource management
  • Excellent discussion of the physical and human interactions that result in land degradation. Material organized as either creative destruction and destructive creation - the two are linked for in the interest of sustaining human population, one must
  • first destroy in order to create. Thoughtful conclusion on how land degradation can be minimized. - (DWG)
Asynchronous terrace development in degrading braided channels
  • Asynchronous terrace development in degrading braided channels
  • This paper describes a process of terrace development in rapidly degrading channels that produces a physically continuous terrace tread that consists of temporally nonsynchronous segments. Moreover, the AA. show that lower terraces developed
  • in the upstream portion of a degrading channel may correlate with higher terrace surfaces developed farther down channel. The results are based upon data collected and observations made in degrading braided channels in a laboratory flume and in a degrading braided
Satellite-based quantification of tree-dominated pasture degradation stages in north-eastern Pará, Brazil
  • Satellite-based quantification of tree-dominated pasture degradation stages in north-eastern Pará, Brazil
  • Brazil ; Forest ; Pará ; Pastureland ; Satellite imagery ; Vegetation ; Vegetation degradation
  • The analysis of the satellite imagery suggested that degradation of pastures were probably underestimated in the past because a considerable part of previous studies classified degrading pastures as secondary forests. Therefore, future climate
  • and carbon models should include a more exact analysis of tree-dominanted pastures to get a more detailed picture of reality. The paper deals with Bragantina, Capoeira, Juquira, pasture degradation, bush encroachment and satellite image classification. - (IfL)
Dominierende und tributäre Bestandteile des fluvialen Abtragungsreliefs. (Principal and tributary components in fluvial degradation relief)
  • Dominierende und tributäre Bestandteile des fluvialen Abtragungsreliefs. (Principal and tributary components in fluvial degradation relief)
  • The formerly proposed concepts of slope of degradation and of initial and dominating lines of erosion as also the processes which account for those phenomena are explicated. Normal and subnormal water-divides and various types of a tributary
  • condition of area within the mechanisms of degradation are discussed. An exact subdivision of fluvial degradation reliefs into components of dominating and of tributary landforms or into corresponding processes of degradation is rendered possible

Grassland degradation in the Three-River Headwaters region, Qinghai Province
  • Grassland degradation in the Three-River Headwaters region, Qinghai Province
  • Biogeography ; China ; Grassland ; Qinghai ; Remote sensing ; Satellite imagery ; Spatial variation ; Vegetation degradation ; Vegetation index ; Years 1970-79 ; Years 1990-99
  • In order to acquire objectively spatial-temporal processes of grassland degradation, MSS images in the mid and late 1970s, TM images in the early 1990s and TM/ETM images in 2004 were used. Grassland degradation in the Three-River Headwaters (TRH
  • ) region was interpreted through analysis on RS images in 2 time series, then the spatial and temporal characteristics of grassland degradation in the TRH region were analyzed since the 1970s. Because grassland degradation had obviously regional differences
  • in the TRH region, it could be regionalized into 7 zones, and each zone had different characteristics in type, grade, scale and time process of grassland degradation.

Agricultural growth, environmental degradation, poverty and nutrition : links and policy implications
  • Agricultural growth, environmental degradation, poverty and nutrition : links and policy implications
  • Agricultural production ; Agricultural technique ; Agriculture ; Environmental degradation ; Nutrition ; Poverty ; Rural development
  • The links and feedbacks between agricultural growth, environmental degradation, and poverty are complex and manifold. This paper examines these linkages under two situations : when new yield-increasing agricultural technologies are available
The global problem of land degradation and desertification
  • The global problem of land degradation and desertification
  • Arid area ; Danube ; Desertification ; Hungary ; Semi-arid area ; Soil degradation
  • Degradation processes within subhumid, semi-arid and arid areas are defined as desertification processes to draw attention to the specific dangerous situation in these areas. Hungary signed the Convention on Desertification, as increasing aridity

The impact of environmental degradation on grain production in China, 1975-1990
  • The impact of environmental degradation on grain production in China, 1975-1990
  • Agricultural productivity ; Agricultural technique ; Agriculture ; Cereal ; China ; Crop ; Environmental degradation ; Regional disparities ; Soil erosion
  • The AA. hypothesize that environmental degradation had a major effect on grain production in many of China's agricultural areas. A nationwide fixed effect grain-yield function is introduced which incorporates both traditional input variables
  • and an additional set of variables that reflect trends in environmental degradation at the provincial level. The model is estimated using time-series data for the period from 1978 to 1980.
An assessment of land degradation in the Northern Province from satellite remote sensing and community perception
  • An assessment of land degradation in the Northern Province from satellite remote sensing and community perception
  • Biomass ; Desertification ; LANDSAT ; MSS ; Perception ; Remote sensing ; Soil degradation ; Soil erosion ; South Africa ; Vegetation ; Vegetation index
  • The assessment of land degradation in developing rural areas of South Africa is often hampered by a lack of reliable data. Remote sensing data offers a reliable source of information. In a case study in the Sekgosese district in northern South
  • Africa, the findings coincided with local community perceptions, although most people were unaware of the causes and effects of land degradation. - (AJC)
