The grassland biome in South Africa can be distinguished from neighbouring biomes on the basis of three climatic indices which are considered to be biologically meaningful. The indices are 'days of growth opportunity' based on soil water availability and calculated using a water budget model, the mean temperature on days when sufficient water is available for plant growth, and the mean temperature on days too dry for growth to occur. The difference between the growth and no-growth...

Abstract The suspended sediment concentration response of three small streams draining quartzites and quartz‐schists in southwestern Nigeria to storms of varying magnitude are presented. A total of 1468 water samples from 62 storm responses with peak stream discharge values ranging from 80 to 120 l s −2 were analysed and storm and suspended sediment concentration hydrographs and hysteresis loops were used to depict the response patterns. The six different types of responses identified...

The two most critical African natural disasters, drought and locust outbreaks, are least understood in terms of the four activities considered essential to long-term disaster reduction: hazard prediction, risk assessment, disaster preparedness and disaster management.

The key to solving the problem...
