    Welfare impacts of climate shocks: evidence from Tanzania 2016
    Also available in:
    No results found.

    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.

    Deep-ocean climate change impacts on habitat, fish and fisheries
    FAO Fisheries and Aquaculture Technical Paper No. 638
    2019

    This publication presents the outcome of a meeting between the FAO/UNEP ABNJ Deep-seas and Biodiversity project and the Deep Ocean Stewardship Initiative. It focuses on the impacts of climatic changes on demersal fisheries, and the interactions of these fisheries with other species and vulnerable marine ecosystems. Regional fisheries management organizations rely on scientific information to develop advice to managers. In recent decades, climate change has been a focus largely as a unidirectional forcing over decadal timescales. However, changes can occur abruptly when critical thresholds are crossed. Moreover, distribution changes are expected as populations shift from existing to new areas. Hence, there is a need for new monitoring programmes to help scientists understand how these changes affect productivity and biodiversity. The principal cause of climate change is rising greenhouse gases and other compounds in the atmosphere that trap heat causing global warming, leading to deoxygenation and acidification in the oceans. Three-dimensional fully coupled earth system models are used to predict the extent of these changes in the deep oceans at 200–2500 m depth. Trends in changes are identified in many variables, including temperature, pH, oxygen and supply of particulate organic carbon (POC). Regional differences are identified, indicating the complexity of the predictions. The response of various fish and invertebrate species to these changes in the physical environment are analysed using hazard and suitability modelling. Predictions are made to changes in distributions of commercial species, though in practice the processes governing population abundance are poorly understood in the deep-sea environment, and predicted

    Alimentación, agricultura y desarrollo rural 2030 en América Latina y el Caribe - Documento Nº 34
    2020
    Also available in:

    El documento presenta una descripción de la estructura del entorno rural, la demografía, la oferta de bienes y servicios, las principales desigualdades, los niveles de pobreza, la importancia y el papel de la agricultura familiar y otras actividades económicas (diversificación), las principales características de la sociedad rural, y la presencia del sector privado. También se discuten las tendencias en la migración y otros procesos sociales o económicos relevantes para la descripción de la situación rural. El texto también analiza la importancia del desarrollo rural para lograr los ODS mediante la identificación de la situación actual y el alcance del cambio requerido para cumplir con los ODS.
