The Global Climatend climate at the global scale. We also show that without understanding vegetation dynamics we are unable to describe long-term climate variability, nor can we fully interpret palaeodimatic reconstructions or predict global weather properly. This chapter is organised as follows (see also Table A.1):

The Sahelian Climatene that started in the 1960s (Nicholson 1978). Many thousands of people died and many more suffered severe disruption of their lives in the severe phases of this drought (e.g. in 1984). The human dramas and socio-economic consequences resulting from drought-induced famines in the Sahel region have p

Summary, Conclusion and Perspectivee (see Sect. A.2.2 and A.2.3). This can be traced back to both developments in modelling as well as the increased availability of sophisticated equipment to study land-surface processes .. In terms of the climate System, it is important to model the partitioning of available energy between sensible

Radiation Measurements in Integrated Terrestrial Experimentsgered by the wellestablished increase in atmospheric content of radiatively active gases. The physical consequence of this increase is an increased longwave radiation of a few W m. from the sky to the surface. The direct detection of this effect would require longwave radiometers — pyrgeometers — wi
