The Costs and Consequences of Harmful Fisheries Subsidies

The world’s oceans are a vital resource for all of us, providing food, livelihoods, and ecosystem services. However, the health of our oceans and the fisheries they support is under threat from a range of human activities, including overfishing, habitat destruction, and pollution.

One of the most significant drivers of overfishing is the use of harmful fisheries subsidies, which are estimated to be worth tens of billions of dollars globally.

A recent study has quantified the number of harmful fisheries subsidies that support fishing in the high seas, domestic and foreign waters. The study found that between 20 and 37 per cent of these subsidies supported fishing in waters outside the jurisdictions of their home nation.

Further, these subsidies primarily originated from developed nations, yet disproportionately impacted developing countries, leading to environmental and societal impacts around the globe.

These subsidies have a range of harmful effects.

First and foremost, they create economic incentives for fishing vessels to continue fishing, even when fish stocks are in decline. This leads to a situation where more and more vessels are chasing fewer and fewer fish, creating a vicious cycle that can lead to the collapse of entire fish stocks.

Furthermore, the environmental and societal impacts of these subsidies are felt far beyond the waters in which fishing is taking place. Overfishing can have knock-on effects on the entire marine ecosystem, affecting everything from coral reefs to seabird populations.

Also, the resource depletion and economic strain caused by overfishing can impact local communities and lead to social instability, making it even harder for vulnerable populations to adapt to the impacts of climate change.

Harmful fisheries subsidies have far-reaching consequences that affect both the marine ecosystem and society as a whole. It is clear that action is needed to curb these subsidies and move towards a more sustainable approach to fisheries management.

Governments must work together to phase out harmful subsidies and redirect funding towards measures that promote sustainable fishing practices and safeguard the future of our oceans. It is time for us to take action to protect our oceans and the valuable resources they provide.

Prolonged Power Outages Amplify Climate Change and Health Inequities

Prolonged power outages caused by weather events have become a significant issue in the United States. Our recent research shows that some parts of the country are hit harder than others, and those already suffering from the effects of climate change and health inequities are most at risk of impact.

The negative consequences of power outages can be dire and pronounced, particularly for vulnerable populations, such as low-income households and those with chronic illnesses. For example, the loss of power can lead to a lack of heating or cooling, which can create health risks. Furthermore, the inability to access electronic medical equipment can be life-threatening for those requiring frequent medical interventions.

Despite the severity of these risks, current practices towards addressing power outages are often short-sighted. With the changing climate, power outages are becoming increasingly frequent, and research shows that United States’ existing infrastructure is not adequately equipped to deal with these demands.

To improve the situation, a comprehensive approach is required, one that considers the health equity implications of power outages. This can involve implementing policies that support the use of renewable energy systems and micro-grids, which can provide reliable power during outages.

Priority should be channeled to measures that support vulnerable populations, prioritizing electricity restoration programs in low-income areas and ensuring that they have access to backup power sources like generators or renewable energy sources like solar energy.

Additionally, it is important to ensure that medical facilities are adequately prepared for prolonged outages, including the ready availability of back-up power supplies.

It’s evident that the existing approach to power outages is insufficient for dealing with the challenges and impacts that loom in the future. To sustainably address this issue, there must be increased focus on a plan that considers the vulnerable populations which are hit the hardest by these outages and align existing/ new strategies with the prevailing climate change realities.

Heatwaves: A Threat to Under-Prepared Regions Across the World

As global warming continues to accelerate, the world is facing a significant threat in the form of heatwaves. Recent studies have revealed that countries which are not adequately prepared for record-breaking temperatures are most at risk of the devastating effects of heatwaves.

These under-prepared regions are likely to face increased fatalities, power outages, and damages to infrastructures. Studies also highlighted that these issues can be particularly challenging for low-income countries, which may lack the necessary resources to respond effectively.

Several regions are especially vulnerable, in which heatwaves are likely to cause the most harm. These include parts of Africa, South Asia, and the Middle East, all of which are experiencing rapid population growth and extreme heat.

Experts have warned that the effects of heatwaves could be particularly severe in urban areas, where the “heat island” effect can cause temperatures to rise higher than in rural areas. In these regions, older adults and children are at a higher risk of heat exhaustion and dehydration.

It is essential that policymakers in affected regions take urgent action to mitigate the effects of heatwaves. This includes investing in infrastructure to improve access to cooling systems, implementing heat warning systems, and educating the public on how to stay safe during heatwaves.

There is an urgent need for countries to become better equipped to deal with the devastating effects of heatwaves.

While not all regions are equally prepared for the challenge, with concerted effort and careful planning, we can reduce the number of fatalities and alleviate the impact of heatwaves on vulnerable populations across the world.
