Book (stand-alone)Impacts of climate change on the production and trade of seafood 2018
Also available in:
No results found.Global seafood production has been increasing steadily in recent decades, at a rate faster that global population growth. Seafood is the most important source of animal protein in several regions, being of particular importance in several African countries. Fish and fisheries products are provided from two main modes of production – fisheries and aquaculture. While fisheries landings has been stagnant since the late 1980s, aquaculture is the world´s fastest growing food production technology. The impact of climate change on global seafood production remains uncertain on aggregate. Recent evidence suggests that global capture fisheries production will remain relatively unchanged, but with significant variation across regions as various species change migration patterns due to direct and indirect effects of climate change. In addition to impacting food security and local economies, this may also cause jurisdictional challenges. Aquaculture production will continue to be the main driver of growth in the seafood sector, and climate change is likely to impact areas where production takes place. If it turns out to be correct that the main impact of climate change on seafood production will be on where production takes place, trade has the potential to serve as an adaptive tool. Places that experience a reduction in production can compensate through imports. Seafood is also better placed than most other foods in terms of capacity to respond to climate change through increased international trade since it is already one of the most traded animal protein products worldwide. Several challenges remain, however, and countries whose fisheries and aquaculture are most vulnerable to climate change are also the poorest with the most limited capacity to adapt. -
Book (series)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. -
Book (stand-alone)The potential impact of climate change on fisheries and aquaculture in the Asian region 2011
Also available in:
No results found.Asia is currently home to 87 percent of all people involved globally in fisheries and aquaculture. The sector contributes significantly to the national gross domestic product of many countries in the region and plays a significant role in food security. Between 15 to 54 percent of the annual protein intake in the region comes from fisheries and aquaculture products. The effects of climate change, such as increasing ocean acidification, shifting food distributions and more frequent cyclones, may increase the negative impacts on capture fisheries already suffering from overexploitation, coastal degradation and pollution. The productivity and viability of aquaculture operations may also suffer negatively from higher sea water levels, flooding, increased competition for water resources and disease occurrence patters. The impacts are likely to be far from uniform and it is expected that the region will face very specific and locally variable challenges. This publication provides insight int o the current state of knowledge about the impacts of climate change in Asia and examines the implications for the fisheries sector. A review of the significance of the findings for policy-makers in the region is provided as well as steps that can be taken to minimize the negative impacts and capitalize on potential opportunities.
