Based on the results of this study, it is recommended that farmers employ innovative agronomic management practices only when the seasonal forecast indicates above normal rainfall. The early availability of seasonal rainfall forecast is thus vital for improved agricultural strategies. Alternatively, farmers are safer if they use conventional approaches, as these have lower associated risks. Increasingly high variability and unreliability of rainfall makes rainfed agriculture in semi-arid areas of sub-Saharan Africa a great challenge.application/pdfenCLIMATE CHANGEAGRONOMIC MANAGEMENT STRATEGIESRAINFALL VARIABILITYAPSIMTANZANIARAIN FED FARMINGCOST BENEFIT ANALYSISAGRONOMYCLIMATE CHANGE VULNERABILITYAPSIMAGRICULTURAL DEVELOPMENTFARMERSConference Paper
