- Description
- The Western Indian Ocean hosts the second largest coastal population on the planet and supports 4 million tons of fish catches annually yielding $943 million in revenues and employment. However, it has been warming at a rate faster than any other region of the tropical oceans over the last century thereby placing the challenges of fluctuating fish supply and changes in ocean productivity on coastal communities. With the global food system under mounting pressure, governments need to understand the relationship between fish supply and food security to avoid overseeing the important role fish and fisheries play in ensuring food security. This study provides an alternative view and measurement of food security at a national level by assessing the impact that macroeconomic variables and climate change have on fish supply in Kenya, South Africa, and Tanzania as case study countries of the Western Indian Ocean. Vector Error Correction Models were run to analyse the impact of economic growth, fishing effort, lending interest rates, and climate change on marine food security for the period of 1980-2016. Agricultural employment was used as a proxy for fishing effort. In general, the relationship between fish supply and fishing effort is negative in the short run and positive in the long run for Kenyan marine fisheries, South African total capture and marine fisheries, and Tanzanian capture fisheries. These results therefore oppose the theoretical expectations. Sea surface temperature, as a proxy of climate change, was found to have a negative impact overall on fish supply and therefore exerts a negative impact on marine food security in all three countries. The results emphasise the need to use disaggregated fisheries statistics to better understand the complex relationship between macroeconomic variables and fish supply. By doing so, more effective food security policies can be created in attempt to mitigate the potential negative impacts of climate change on marine food security in the Western Indian Ocean.
