Figures and Tables

Figure 1. The Miombo Landscape: (a) a plan section showing the interdigitation of woodland (stippled) and dambo grasslands (clear); (b) a cross-section profile down a catena showing variations in soil properties and vegetation structure (topographic details and data on organic carbon, cation exchange capacity (CEC) and total exchangeable bases (TEB) from Webster (1965).  The rolling relief is typical of the undulating erosion of the Central African shield.
 
Figure 2. The distribution of miombo ecosystems as defined by this project. The total area is 2.8 million km2.

Figure 3. Composite of sub-pixel high temperature sources (active fires) derived from daily NOAA-AVHRR 1-km satellite data from August through October 1992.

Figure 4. Flow chart of the proposed Palaeoecological Experiment on Miombo.  The circled numbers correspond to Core Experiment 5, Activity 2, Tasks 1-4 in the text, T and P are temperature and precipitation.

Figure 5. Interactions between land surfaces and the atmosphere.  Boxes denote the atmosphere and the three components of land-atmosphere interactions: biophysics, biogeochemistry, and ecosystem state. Text within boxes indicate important state variables.  Arrows indicate variables exchanged between component models. Ecosystem state affects biogeochemistry and biophysics through community composition, leaf area index, canopy height, cover type, and carbon, phosphorus and nitrogen pools (modified from Bonan 1995).
