  • This article illustrates that the study of landscape changes requires more than land use statistics; a useful approach must be based on spatial sampling. It suggests that tracing the use of a specific unit of land through history can be an efficient
  • way of decoding spatial messages and translating them into information about the dynamics of the agricultural resource management strategies. Selected cases from different agroecological environments, in Denmark, Burkina Faso and Niger, are presented.

  • This paper will present a computer model of a certain class of agricultural systems, termed shifting cultivation systems. The objective of modeling is to demonstrate how such decision rules control overall system behaviour, and to study the response
  • of the system to an increase in population density.

  • resource database, a classification of the land use changes in the period 1979-1989 and 1994 was conducted using air photos and satellite images. Finally the land use change was analysed using a geographical information system. The produced maps create
  • a basis for the development of a land use planning system.

  • L'A. décrit les classifications des cours d'eau au Danemark. Il discute les critères de caractérisation, classification et régionalisation, puis présente une première approche d'un système de classification combinant les facteurs biotiques et

  • Within the broad diversity of global vegetation types this paper focuses on the carbon assimilation of 4 vegetation types whose locations range, from 75°N to 15°N : the Sahel, central Spain, boreal Sweden, and northeastern Greenland. All 4 systems
  • function under marginal conditions, limited either by heat or water supply. By combining eddy covariance measurements and CO2 exchange modelling, the sensitivity of these systems related to temperature change is evaluated.

  • The A. outlines aspects of the new paradigm for dryland ecosystems and pastoral production systems. With the new paradigm a coherent theory is provided linking the dynamics of drylands with pastoral strategies. Consequences of the new paradigm
  • are analysed from a theoretical point of view, emphasis is on implications for pastoral mobility with a focus on pastoral systems in West Africa. In an example from Ferlo, Senegal, different types of pastoral mobility are discussed with special focus
