Synopsis (short abstract) Sub-Saharan Africa (SSA) remains the world’s most food-insecure region characterized by high levels of child mortality and poverty and low levels of human and physical capital (FAO, 2009). Countries in SSA, including Tanzania, heavily depend on a smallholder-based agricultural sector, which makes their welfare and food security particularly vulnerable to climate change (Barrios et al., 2008). The goal of this study is to provide a comprehensive analysis of the impact of weather risk on rural hou seholds’ welfare in Tanzania using nationally representative household panel data together with a set of novel weather variation indicators based on interpolated gridded and re-analysis weather data that capture the peculiar features of short term and long term variations in rainfall and temperature. In particular, we estimate the impact of weather shocks on a rich set of welfare indicators (including total income, total expenditure, food expenditure and its share in total expenditure and calori e intake) and investigate whether and how they vary by different definitions of shocks - capturing changes in levels and variations over different time periods. We find that both rainfall and maximum temperature variability exert a negative impact on welfare (i.e. no consumption smoothing) and that households that have adopted SLM practices are able to achieve income-smoothing. We also find that the most vulnerable rural households are much more affected by a rainfall deficit compared to the hou seholds in the top income quantile. Results underline the key role extension services play in enhancing adaptive capacity to reduce vulnerability to adverse weather conditions, as well as the importance of targeting the most vulnerable households in policy interventions to improve food security in the face of weather shocks.

    Welfare impacts of climate shocks Evidence from Uganda 2016

    This paper evaluates the effects of weather/climate shocks on various measures of household welfare using a nationally representative panel data from Uganda National Panel Survey (UNPS) together with a set of novel climate variation indicators. We estimated generalized least square (GLS) random effects and quintile regression models to address the research questions. Our results point towards a consumption and income smoothing behaviour by the households since: we obtain very few significant results with respect to climate/weather shock variables togetherwith highly significant effects of the socio-demographic and wealth control variables. We also investigate if different shocks definitions, i.e the reference period used to define the shock, modifies our results. The latter are robust since the coefficients and the signs do not change with the reference period. We further test the hypotheses that policy-relevant mechanisms can be effective means of mitigating the negative welfare effects. For instance access to credit services and use of sustainable land management practices enables the households to contain the negative effects of climate shock on per capita food consumption from own produced crops but not the case for some of the outcome variables.

    The Government of the United Republic of Tanzania estimates that nearly 35 percent of households in Kagera and Geita regions lives below the basic needs poverty line, with some districts within these regions ranked among the poorest in the country Most production is for subsistence, with farmers’ households generally living season to season, with very small risk margins and little resilience to weather and climate related shocks Agriculture, including the crops and livestock subsector contributes over 87 percent of the country’s regional Gross Domestic Product ( Of the total population of approximately 4 million in the regions, more than 3 5 million residents rely on agriculture for their livelihoods Almost all agriculture and farming in the regions is rainfed and climate change has been intensifying the variability of rainfall patterns, affecting the sector seriously The profound impacts of climate change in Kagera and Geita regions are already causing relatively more intense and wider damage to at risk communities and agro ecosystems, compared with other regions in the country.

    Climate-smart Agriculture Guidelines for the United Republic of Tanzania 2017
    Also available in:

    This guideline is an instructive tool that highlights key climate change and agricultural risks in the United Republic of Tanzania and provides information on mainstreaming climate change adaptation and mitigation objectives within rural development. It provides guidance on how this could best be achieved through the implementation of the CSA approach, in line with other policies related to agriculture sectors, food and nutrition security, and climate change. Its goal is thus primarily to inform on the implementation of the CSA framework and to describe the CSA practices and technologies best suited for different regions and agro–climatic zones of the country.
