  • Use of sensitivity analysis to evaluate key factors for improving slash-and-burn cultivation systems on the Eastern Escarpment of Madagascar
  • Development strategy ; Environmental degradation ; Farming system ; Land use ; Malagasy Republic ; Mountain ; Resource management ; Sensitivity analysis ; Slash and burn agriculture
  • The slash-and-burn pluvial rice cultivation that predominates in the agriculture of the Eastern Escarpment of Madagascar is causing ecological degradation and is aggravating poverty. Study uses sensitivity analysis, which uses existing knowledge
  • to set priorities among key factors associated with a development objective. Key factors in promoting sustainable development were found to be intensification and compact production units of cash crops (fruits and vagetables), irrigated rice
  • , and integrated livestock production. Interventions in land access and marketing were found to be the most important factors in inducing such change. - (SLD)

  • Reference value of old people's hematocrit and geographical factors
  • China ; Elderly people ; Health ; Regional disparities ; Regression analysis
  • The paper provides a scientific basis for a unified standard of the reference value of Chinese healthy old people's hematocrit. It is found that the altitude is the most important factor affecting this reference value.

  • their temporal and spatial variation. Both methods of analysis produced 2 very important uncorrelated modes of variability in January and July, indicating that the transient heat fluxes are influenced by few controlling factors. The AA. suggest that these modes
  • In this paper principal component analysis (PCA) and singular value decomposition (SVD) are used to define the importance of the variables contributing to the relationship between the transient latent and sensible heat fluxes and to show

  • Identification and analysis of root causes of desertification in semi-arid region of China - a case study from Ejin Horo Banner, Inner Mongolia
  • A case study on the driving forces of desertification in the semi-arid region was carried out in the Ejin Horo Banner. The occurrence and development of desertification were demonstrated and its driving factors were identified and analyzed
  • . The results obtained indicated that over-reclamation of land, overgrazing and denudation of natural vegetation cover were immediate and dominant factors causing land vulnerability to desertification. For a better understanding of the deep-rooted causes

  • Computer program for stability analysis of steep, cohesive riverbanks
  • The computer program presented here is based on an analysis developed by Darby and Thorne. The software takes account of the geotechnical characteristics of the bank materials, the shape of the bank profile, and the relative elevations
  • of the groundwater and surface water to estimate stability with respect to mass failure along a planar-type failure surface. Results can be displayed either in terms of a factor of safety (ratio of resisting to driving forces), or probably of failure. The computer
  • analysis is able to determine the relative amounts of bed degradation and bank-toe erosion required to destabilize an initially stable bank.

  • This thesis examines the effects of stress factors and the potential of recovery and restoration in freshwater wetlands. Impacts of changes in environmental conditions on wetland vegetation are studied by comparing wetlands in both stressed
  • landscapes in the Netherlands and fairly undistributed landscapes in the Biebrza valley in Poland. The Biebrza valley acts as a reference wetland in this analysis. In the second part of this book experiments with the restoration of acidified and eutrophicated

  • In this paper karr landforms typical for dolomite surfaces were investigated by the authors using methods of field observation, mapping and morphological analysis. Through the mapping of these landforms and of the subsurface bedrock, data were
  • obtained about mechanisms of formation and factors influencing the process. Observations were made on the circumstances of the occurence of conspicuous karr forms, and recommendations were put forward related to landform protection and nature conservation
