Photo: Rod WaddingtonEarly warning systems (EWSs) have been effective in reducing loss of life and injury associated with extreme weather events, but it is less clear what influence they have on other household decisions. Some research has identified increased productivity in rainfed farming from using weather and climate information, but much less is known about fishing communities, where livelihoods also depend heavily on the weather.This paper begins to fill this gap by examining the range of socio-economic benefits associated with improvements in EWSs in coastal areas of Tanzania, including for fishing communities and the marine sector. It uses the Triple Dividend of Resilience (TDR) framework, developed by ODI, the World Bank and the London School of Economics, to capture the direct, indirect and co-benefits of investments in disaster risk reduction.Key messagesImproving the communication of extreme weather information in Tanzania through the Multi Hazard Early Warning Service (MHEWS) project has helped to reduce mortality and property damage when storms and floods hit.Evidence from a study in the coastal region of Tanga suggests that there are other ‘co-benefits’ from investment in early warning systems. Fishermen and seaweed farmers are better able to plan their economic activities, and some have seen a rise in income.However, lower levels of risk from better preparedness do not appear to have encouraged higher levels of saving and investment because of other limiting factors – fishermen are poor with little capacity to save without access to microfinance.The TDR framework can help to identify the full range of benefits associated with functioning EWSs, strengthening the business case for making these and associated investments.Read the research The ‘triple dividend’ of early warning systems: evidence from Tanzania’s coastal areasDocumentpdfRelated Anticipatory action for livelihood protection: a collective endeavourA discussion of how anticipatory action can protect livelihoods, with a particular focus on the case of drought.Working and discussion papers11 June 2020 Integrating ‘anticipatory action’ in disaster risk managementA briefing note on the integration of anticipatory action in disaster risk management.Briefing papers3 April 2020 The governance of Nepal’s flood early warning system: opportunities under federalismThis paper looks at the institutional mechanisms to assess, monitor, communicate and respond to flood risk information in three river basins in Nepal.Working and discussion papers27 August 2019See more:disaster risk reductionclimateresiliencejobs and livelihoodsTanzania
