“…The negative impacts of sea surface temperature, rainfall, typhoons, and wind speed on catch yields are also found in various literature in Vietnam [ 61 ] and other places [ 17 , 27 , 42 , 47 , 62 – 64 , 71 , 73 , 84 ]. For instance, Garza-Gil, Torralba-Cano [ 84 ] report a 10% rise in temperature leading to a 1.4% annual decrease in the European sardine fishery’s profit.…”

“…The production function is widely used in literature to describe the relationship between outputs and inputs in agriculture and fisheries [ 42 , 47 , 65 – 68 ]. Following Conrad [ 69 ], the Cobb-Douglas function is served as a base to develop the projection model.…”

“…There are several approaches to analyze the various aspects of climate change impacts, such as vulnerability [ 5 , 33 – 36 ], adaptation and mitigation [ 6 , 37 – 41 ], and economic impact [ 27 , 28 , 42 – 46 ]. Since welfare is the primary concern of this study, its approach should fall in the range of economic issues.…”

Welfare impact of climate change on capture fisheries in Vietnam

Fisheries are forecasted to shrink in the tropics due to climate change. In Vietnam, fisheries are a pro-poor economic sector and essential nutrition source; however, welfares of producers and consumers in the climate change context are not well understood. While most studies focus on the gains or losses of total products and revenues, this paper pays additional attention to the changes in surpluses of market players in the long run. A combination of the production function, demand and supply functions, and partial equilibrium analysis is employed to measure the production and welfare impacts based on time series data from 1976 to 2018 and a Vietnam household living standards survey in 2018. The results show that relative to the present, catch yield is likely to reduce 35%-45% by mid-century and 45%-80% by the end of the century. Consumers may lose their surplus of 7-9 billion USD (PPP, 2018) by 2035 and 10-18 billion USD by 2065 due to supply reduction, while producers may gain additional profit of 3.5-4.5 billion USD by 2035 and 5-9 billion USD by 2065 owing to a price increase. The research findings suggest that Vietnam could impose measures to limit capture effort, as set out in the Law of Fisheries 2017, without harming fisher welfare. The expansion of aquaculture could reduce the gap between supply and demand of wild fish to mitigate consumer welfare loss; however, this impact is still ambiguous.

“…The result shows positive impact on GDP in Iceland and Greenland. Ibarra et al (2013) examined economic impacts of climate change in Mexican coastal fisheries in terms of shrimp and sardine fisheries. They found climate change causes a decrease in shrimp production and a high degree of variability and uncertainty of sardine fisheries stocks.…”

Climate change and its impact on fisheries is a key issue for fishing nations, particularly the Philippines. The Philippines is highly vulnerable to the impacts of climate change on fisheries and it can lead to economic shock on the nation's economy. This paper examines the impact of climate change on marine capture fisheries in the Philippines using a computable general equilibrium (CGE) model to elaborate and project impacts on the national economy. In the simulation, one baseline scenario and two climate change scenarios based on greenhouse gas concentration-RCP 2.6 and RCP 8.5-were considered. The model focuses on Gross Domestic Product (GDP) and income distribution by region, which can represent economic conditions in terms of economic growth and distribution. Results show that there will be a negative change on both the fisheries and economic variables where more extreme changes in climate occur.
