Optimum Fisheries Management under Climate Variability: Evidence from Artisanal Marine Fishing in Ghana

For migratory seabirds, staging and wintering areas may be important targets for conservation. Declines of Roseate Tern Sterna dougallii populations have led to conservation initiatives at breeding sites on both sides of the North Atlantic. However, these could be compromised by environmental conditions in non‐breeding areas. The migratory ecology of Roseate Terns is poorly known and we used light‐level biologgers (geolocators) to identify the migratory routes, staging and wintering areas of Roseate Terns from two European colonies. Most birds wintered off the Ghanaian coast in the Gulf of Guinea, but some wintered further west off Sierra Leone and Liberia, or changed locations during the winter. In these areas, cold‐water upwellings of the Guinea Current Large Marine Ecosystem (GCLME) may provide vital foraging resources. Geolocations in combination with temperature measurements and satellite sea‐surface temperature data show that cold‐water upwellings of the Canary Current Large Marine Ecosystem (CCLME) were important areas for migratory staging, particularly on the return migration which was slower than the outward journey. These results emphasize the importance of productive cold‐water upwellings in the migratory ecology of Roseate Terns. The GCLME and CCLME are under threat from over‐exploitation, pollution and climate change; effective conservation of these environments will be important to secure the long‐term future of these and other seabirds.

In recent decades, fishing sustainability has been subject to intense international debate. Overfishing and contamination of the marine environment are elements that contribute to a reduction in fish stock and catches, often leading to declining income and employment, especially in rural areas. We present a sustainable fisheries model that promotes artisanal fishing while incorporating replacement rates of fish stock and actions that benefit the fishing industry. First, the sustainable fisheries model defines the guidelines and actions that may apply either together or independently, sequentially, or simultaneously, according to a defined budget. These concrete actions are quantified and incorporated into an environmentally extended input-output model to evaluate the economic impact on the Spanish fishing industry. The impact is complemented with an assessment of social impact (employment) and environmental impact (estimated reduction of CO2 emissions).

“…In addition, along with the extensive coastal development, the environment of China's coastal waters has been profoundly influenced by land-based pollution in recent decades [7], which has further led to habitat loss and depletion of fishery resources [8,9]. Climate change complicates the challenges currently facing China's marine fisheries and poses an enormous threat to the development of marine fisheries [10][11][12][13].…”

China’s marine fisheries are undergoing large-scale environmental changes associated with climate change, marine pollution, and overfishing. The assessment of marine fisheries vulnerability has become extremely necessary for fisheries management and sustainable development. However, studies on China’s marine fisheries vulnerability remains sparse. This study aimed to provide an analysis of the inter-provincial level vulnerability of China’s marine fisheries under multiple disturbances. The vulnerability measure was composed of exposure, sensitivity, and adaptive capacity indicators specific to marine fisheries based on the Intergovernmental Panel on Climate Change (IPCC) definitions. Results showed that Liaoning, Hebei, Fujian, and Hainan provinces appeared to be the most vulnerable; Shanghai appeared to be less vulnerable among China’s 11 coastal provinces; and the key sources of vulnerability differed considerably among coastal regions. The high vulnerability regions could be divided into two different patterns according to the combination of exposure, sensitivity, and adaptive capacity, but they all had one thing in common: relatively low adaptive capacity. While some existing coercive measures to reduce dependence on fisheries were found to be helpful in China, the reality showed that appropriate adaptation measures such as improving fishermen’s education level and increasing vocational training may be helpful in enhancing the existing policy effectiveness.
