Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empir

The vegetation of the miombo woodland is a highly heterogeneous phenomenon which makes it hard to assess biomass. Hence very little is known of their carbon dynamics and factors causing biomass variations. Estimating forest biomass is the first step

Water availability has frequently been linked to seasonal leaf display in seasonally dry ecosystems, but there have been few ecohydrological investigations of this link. Miombo woodland is a dominant seasonally dry tropical forest ecosystem type in s
