  • Editorial. German research in human geography of the Mediterranean area in Mediterranean regions.
  • Mediterranean agriculture - an agro-ecological strategy
  • Agricultural practice ; Agriculture ; Agroecosystem ; Arid area ; Concept ; Irrigation ; Land use ; Mediterranean States ; Mediterranean area ; Rural landscape
  • The Mediterranean region is an area of heterogeneity. Consequently the Mediterranean agriculture is an agro-ecological strategy, an adjustment to particular climatic conditions in Mediterranean zones. In traditional agriculture the components could
  • be combined in an integrated system. In modern, specialized agriculture the Mediterranean agriculture to a higher degree becomes a type on a regional level. Agricultural types determine the landuse and are important for the development of rural landscapes.
  • The innovation of greenhouse crops in the Mediterranean area : the Turkish case in Mediterranean regions.
  • The wied : a representative Mediterranean landform
  • Malta : at the crossroads of the Mediterranean
  • Climate ; Climatic geomorphology ; Drainage network ; Malta ; Mediterranean area ; Slope deposit ; Valley
  • With such a limited area and range of rock type, Malta cannot provide anything approaching a representative sample of the landforms which occur in the Mediterranean Basin. However, few geomorphological features can be considered unique
  • to the Mediterranean, since they are shared either by the more humid temperate climates to the north or the semi-arid regions to the south and east. The wied, a hybrid between the humid temperate and semi-arid climates, might be considered a truly Mediterranean
  • Runoff and erosion processes after a forest fire in Mount Carmel, a mediterranean area
  • Special issue : mediterranean erosion
  • Forest fire ; Israel ; Mediterranean area ; Mountain ; Rill wash ; Sediment budget ; Soil erosion ; Water erosion
  • In the mediterranean forest area of Israel, fires increase runoff and sediment yield rates relative to undisturbed forested land. This study aims to : 1) determine the rates of water runoff and sediment yield from burnt slope sites, related
  • to unburnt areas; 2) analyze the factors affecting the geomorphic processes.
  • Response of past and present Mediterranean ecosystems to environmental change
  • Adaptation ; Biodiversity ; Climatic variation ; Desertification ; Ecosystem ; Holocene ; Human impact ; Mediterranean States ; Mediterranean area ; Quaternary
  • and coupling of Mediterranean, North Atlantic and Greenland records. For the Holocene, there is continued debate about the relative impact of anthropogenic activity, but there is also increasing recognition that mediterranean-type ecosystems should
  • Tourism and the environment: limitations and contradictions in the EC's Mediterranean region
  • Environment ; Italy ; Mediterranean area ; Nature conservation ; Reception capacity ; Tourism ; Tourism policy ; Tourist facilities
  • Small basin response in a mediterranean mountainous abandoned farming area : research design and preliminary results
  • Badland ; Catchment area;Watershed ; Clay ; Fallow land ; Farming;Agriculture ; Mediterranean area;Mediterranean region ; Mountain ; Pyrénées ; Spain
  • Cal Parisa basin (eastern Spain), was selected as a representative of extensive areas on clayey bedrock formerly used for farming, nowadays almost abandoned, where badlands are of great importance as far as sediment production is concerned.
  • The chronology of human cultures in Europe and the Mediterranean Basin according to 14C dating
  • Archaeology ; C 14 dating ; Civilization ; Europe ; Mediterranean States ; Palaeogeography ; Postglacial ; Quaternary
  • 14C ages related to human cultures, cultivated plants and native flora in Europe and in Mediterranean area allowed us to build a time succession for the evolution of the human cultures compared with cultivations and the diffusion of native flora
  • Properties and geographic relevance of frangipan and other close-packed horizons in a non-glaciated mediterranean region
  • Alluvium ; Colluvium ; Italy ; Mediterranean area ; Soil ; Soil properties ; Toscana
  • To investigate the properties of different close-packed horizons present in soil evolved from mainly siliceus colluvia and alluvia in a Mediterranean environment several profiles were selected and analysed. - (MR)
  • Effects of fire and of clearing in a mediterranean Quercus ilex woodland : an experimental approcach

  • Soil erosion at three experimental sites in the Mediterranean
  • Agricultural land use ; Arid area ; Europe ; Greece ; Italy ; Mediterranean area ; Rill wash ; Sediment budget ; Slope ; Soil degradation ; Soil erosion ; Spain ; Vegetation
  • The basic objectives of this study are to interpret the runoff and sediment yield results derived from 3 field sites in the Mediterranean basin, (Italy, Greece, Spain), under comparable bioclimatic conditions. The conclusions from the erosion
  • studies carried out at each of the 3 sites can possibly be applied in finding solutions for soil erosion problems in the Mediterranean basin.
  • Soil landscapes and drainage basins in Mediterranean mountain areas
  • Analysis of the interrelations between soil landscapes and drainage basins in a mountain area of acid substrates. The climate is Mediterranean continental. The results obtained seem to demonstrate the existence of marked causal connections
  • Temperate and semi-arid tufas in the Pleistocene to recent fluvial barrage system in the Mediterranean area : the Ruidera Lakes Natural Park (Central Spain)
  • Albacete ; Carbonate ; Dam ; Lacustrine sedimentation ; Lake ; Mediterranean area ; Quaternary ; Sedimentary ; Spain ; Th/U dating ; Tufa
  • The main aims of this article are to illustrate the genesis and evolution of a temperate semi-arid fluvial Pleistocene to Recent carbonate system in a Mediterranean area and to establish the different stages of tufa formation and its
  • Clay illuviation in Red Mediterranean Soils
  • Special Issue. Red Mediterranean soils
  • Aeolian dust ; Arid area ; Carbonate ; Clay mineral ; Climatic variation ; Concept ; Dating ; Geochemistry ; Lateritic soil ; Mediterranean States ; Mediterranean area ; Red soil ; Soil ; Soil classification ; Soil properties ; Taxonomy
  • This paper shows the reality of clay illuviation in Red Mediterranean soils under present day environmental conditions, and examines the effects of time and climatic fluctuations during Holocene and Pleistocene on this soil forming process. Textural
  • features and fabrics existing in Red Mediterranean soils are inventoried. The problem of age determination is also addressed, through the use of radiometric dates and correlation with archaeological artifacts.

  • Topographical thresholds for ephemeral gully initiation in intensively cultivated areas of the Mediterranean
  • Concept ; Cultivated land ; Gully erosion ; Mediterranean area ; Murcia ; Portugal ; Rill wash ; Slope gradient ; Soil erosion ; Spain ; Threshold ; Watershed
  • Ephemeral gullying is an important erosion process in Mediterranean areas. The objective of this study was to investigate to what extent one could use field measurements of S (local slope) and A (drainage-basin area) to predict the location
  • of ephemeral gully initiation in intensively cultivated Mediterranean environments. Two relatively homogeneous study areas in Southeast Spain and Northeast Portugal with widespread ephemeral gullying were selected.
