Content

Drought has significant impacts on domestic use, agriculture, and ecosystems in Tanzania and is a major seasonally occurring stress factor in water resources management. Water shortage is projected to increase with globally rising temperatures and this will likely be one of the major limitations for future development in Tanzania. Instrumental records of drought variability are sparse in Tanzania and cover only a short period of time, but regional tree-ring records can provide reliable information about longer-term water availability. We here present a drought-sensitive tree-ring chronology based on 58 Brachystegia spiciformis trees from two sites in the Miombo woodland of southern and western Tanzania.The chronologies were compared to monthly and seasonal instrumental climate data (Tabora and Morogoro stations; 1892-2011).Annual growth rings in Brachystegia spiciformis reflect rainy season (December-February) precipitation variability.Our tree-ring chronologies extended back to the 19th Century and can thus provide an improved benchmark for sustainable water use in Tanzania
