The A. outlines the simplified urban belts of Budapest with specific features and spatial processes of the population growth and changes. It can be stated that the consequences of the economic transition after 1989 affected these urban belts in very
different ways. The changes, taken place in the social and functional structure of Budapest are displayed by various socio-economic indicators. The sectorial and group interests concerning the spatial development of the town and the different urban belts
Le point sur les récents travaux concernant la télédétection et ses applications: l'étude du changement global; la surveillance de la pollution; les conséquences des feux de forêt.
An appreciation of time on a variety of scales may help explain the complexity of tropical rain forests and provide a frame of reference to consider the consequences of anthropogenic deforestation and global climatic change on this biome. Here
the A. reviews published tropical rain-forest research that has focused on the time dimension from late 1992 until early 1994.

This paper reviews recent elderly population trends in the towns and metropolitan areas of Great Britain with particular attention to changing age-group and spatial distributions, housing amenities and long-term illness.
Effects of changes in groundwater level on palsas in central Iceland
The effects of the changed hydrological conditions on 5 palsas were monitored over a period of 5 years. All the palsas increased in height. A core through one palsa showed that while it was formed by segregation ice, the observed height increases
La situation de l'emploi et son changement à Budapest
The study attempts to review the changes of the number and structure of active earners in Budapest, showing the most important spatial characteristics of the restructuring of labour force between 1970 and 1993. The changes in the number

Transport choices and sustainability: a review of changing trends and policies
This article reviews current developments in transport trends and policies and considers their impact on urban and regional change into the 21th century. It confirms the fundamental shifts now taking place in the transport sector. The global impact
of these changes is considered. There is an assessment of transport choices and policies in the more advanced world economies with special reference to Europe and North America.
Population and politics in a plural society: the changing geography of Canada's linguistic groups
The paper examines the role of population change as it reflects and shapes the political and cultural relations between French and English speakers in Canada. These two groups are concentrated in different regions. These questions are conditioned
by the linguistic landscape and by the nature and direction of population change. Linguistic affiliation determines one's propensity to remain within a region and guides the choice of destinations. The bifurcation of Canada into unilingual regions will be renforced.
Gravel transport and morphological change in braided Sunwapta River, Alberta, Canada
The relation between morphological change and patterns of variation in bedload transport rate in braided streams was observed by repeated, daily topographic surveys over a 25 day study period in a 60 m reach of the proglacial Sunwapta River, Alberta
, Canada. There are two major periods of morphological change, each leasting several days and each involving the complete destruction and reconstruction of bar complexes.
Floodplain sediments on the divide between Huang He and Chang Jiang, Gansu province, NW China
Landscape and Quaternary climatic changes in eastern Tibet and surroundings
Results and discussion of a stratigraphic survey made of a 21-m-profile of floodplain sediments on the watershed between the Chang Jiang (Yangtze River) and Huang He (Yellow River) at 2500 m asl.: distribution of the floodplain deposits
Climatic changes, desertification and the Republic of Sudan
Meteorological data for a period of 30 to 50 years was analysed to ascertain the climatic changes in the Republic of Sudan. The study confirms that the temperatures are rising and rainfall declining. Rigorous analysis of relative humidity, clouds
, radiation and evaporation also confirms the changing pattern, a trend which may accelerate environmental degradation and desertification in Sudan.
