Droughts are one of the most serious threats to water availability, food security, and local livelihoods in the semi-arid areas of Tanzania. This paper adapted the participatory vulnerability assessment tools (causal effects, social mapping–resource mapping–social services–mobility–seasonality) to analyze the effects of prolonged droughts on semi-arid farming systems, community's vulnerability to drought effects, and the adopted coping strategies in six villages of Chamwino and Mwanga districts. Crop failure, loss of pasture, and drying of water sources were the common and major negative effects of droughts. Their consequences included food shortage and insecurity, water scarcity, and loss of livestock. The vulnerability to these effects was found to be driven by the social condition of households, resource ownership, and type of income sources. Those with good social conditions, relatively resourceful and deriving incomes from crop-livestock integration or non-agriculture, were less vulnerable and better placed to cope with the effects of droughts. Investments that build the productive resource base of a household and improve access to domestic and livestock water will contribute to long-term adaptive and drought-resilient systems in semi-arid areas of Tanzania.

Browse species are important food resources in semi-arid areas, especially during the dry season when the nutritive value of grass is at its lowest. However, browse plants often contain secondary plant compounds which limit their nutritive value. Proanthocyanidins (PAs) (also called condensed tannins) and related flavonoids are a common constituent of woody plants in tropical regions (Mangan, 1988). PAs cause a bitter and astringent taste which lowers food palatability and they also lower the digestibility of proteins and carbohydrates (Jacksonet al., 1996). PAs also interfere with current chemical methods that are used for estimating nutritive value of foods (Reed, 1995). Biological assays, especially ,in vitrotechniques, have a potential to reflect better the nutritive value of foods that contain PAs. Thein vitrogas production technique has been found to reliably predict the nutritive value of temperate forages (Makkaret al., 1996). There has been limited research on its efficacy with tropical forages. The experiment reported here was conducted to test the hypothesis that gas production of tropical browse species reflects their content of fibre, protein and/or PAs.
