Human Impact and the Ocean Economy

Visualizing the Human Impact on our Ocean Economy

When you think of economic output, it’s likely the ocean isn’t the first entity that comes to mind. But from facilitating international trade to regulating the climate, the “blue economy” contributes significant value in both tangible and intangible ways.

The sustainable use of the ocean and its resources for economic development and livelihoods have such far-reaching effects, that its protection is a significant goal of the United Nations, as well as for many other countries and organizations throughout the world.

However, these vital ocean assets are in danger of sinking quickly. Ahead of World Oceans Day on June 8, 2020, we look at the total value of assets that come from our ocean, and how various human activities are affecting these resources.

Global Ocean Asset Value

Economic value from all the oceans is measured both by their direct output, as well as any indirect impacts they produce.

According to the World Wildlife Fund, these combined assets are valued at over $24 trillion. Here’s how they break down:

  • Direct Output: Marine fisheries, coral reefs, seagrass, and mangroves
    Total value: $6.9T
    Examples of direct output: Fishing, agriculture
  • Trade and Transport: Shipping lanes
    Total value: $5.2T
  • Adjacent Assets: Productive coastline, carbon absorption
    Total value: $7.8T, and $4.3T respectively
    Examples of services enabled: Tourism, education/conservation (such as jobs created)

In fact, the annual gross marine product of the oceans is comparable to the Gross Domestic Product (GDP) of countries, coming in at $2.5 trillion per year—making it the world’s eighth largest economy in country terms.

Unfortunately, experts warn that various human activities are endangering these ocean assets and their reliant ecosystems.

The Cumulative Human Impact on Oceans

An 11-year long scientific study tracked the global effect of multiple human activities across diverse marine environments. The researchers identified four main categories of stressors between 2003-2013.

  1. Climate change: Sea surface temperature, ocean acidification, and sea level rise
  2. Ocean: Shipping
  3. Land-based: Nutrient pollution, organic chemical pollution, direct human pollution, light pollution
  4. Fishing: Commercial and artisanal fishing, including trawling methods

Across the board, climate stressors were the most dominant drivers of change in a majority of marine environments. Similarly, pollution levels have also increased for many ecosystems.

Plastic pollution is especially damaging, as it continues to grow at unprecedented rates, with a significant amount ending up in the oceans. The World Economic Forum estimates that by 2050, there could be more plastic in the ocean than fish by weight.

Among the various marine environments, coral reefs, seagrasses, and mangroves proved to be most at-risk, experiencing the fastest increase in cumulative human impact. However, these are also the same ecosystems that we rely on for their direct economic output.

Overall, climate-induced declines in ocean health could cost the global economy $428 billion annually by 2050.

The Ocean Economy is in Hot Water

It can be difficult to truly understand the scale at which we rely on the ocean for climate regulation. The ocean is a major “carbon sink”, absorbing nearly 30% of the carbon emitted by human activity. But acidity levels and rising sea surface temperatures are changing its chemistry, and reducing its ability to dissolve CO₂.

According to the UN, ocean acidification has grown by 26% since pre-industrial times. At our current rates, it could rise to 100-150% by the end of the century. Overfishing is another urgent threat that shows no signs of slowing down, with sustainable fish stocks declining from 90% to 66.9% in just over 40 years.

To try and counteract these issues, this year’s virtual World Oceans Day is focused on “Innovation for a Sustainable Oceans” to discuss various solutions, including how the private sector can work with communities to maintain the blue economy. In addition, there’s a petition in place to urge world leaders to help protect 30% of the natural world by 2030.

Will our human activities continue to stress the ocean economy, or will we be able to positively reverse these trends in the years to come?

MegaMilk: Charting Consolidation in the U.S. Dairy Industry

This graphic charts the American dairy industry’s shift in milk production from small commercial farms to fewer, larger farms.

MegaMilk: Charting the Consolidation of the Dairy Industry

Today’s dairy industry looks very different to how it did just 30 years ago.

Milk production in the U.S. has increased by a whopping 50% over that time frame—yet, the total number of dairy farms has dropped by three-quarters.

Fewer and larger farms now have the lion’s share of all U.S milk cow inventory. While they have the ability to produce more competitively priced dairy products and provide more value to consumers, it is causing financial devastation for small farmers.

The graphic above uses data from the USDA to chart the rapid consolidation of the American dairy industry between 1992 and 2017.

The End of the Small Dairy Farmer?

In the U.S., the dairy industry is one of the fastest consolidating industries in comparison to almost all other agricultural sectors.

Between 1992 and 2017, small commercial farms with 10-99 cows saw an average decline of 70%. These farms accounted for 48.5% share of all U.S. milk cows in 1992. In 2017, that number stood at just 12.2%.

Over time, small farm production has been replaced by that of bigger and more consolidated “megafarms”—a move that can be attributed to the many benefits that scale brings, such as lower costs of production and the potential to compete in the international market.

The Need For a Survival Strategy

While small dairy farmers simply cannot keep up with larger farms encroaching on their turf, they also have fluctuations in dairy prices to contend with. Milk prices fell in 2018, narrowing the gap between milk prices and feed costs so much that another wave of farm closures ensued.

To make matters worse, many small dairy farmers are close to retirement age, and according to the USDA, exits are more likely if the farm operator is 60 or older.

Despite the hardship facing small dairy farmers, analysts suggest that consumer backlash against large-scale production could present opportunities for small dairy farmers to create premium artisanal products. However, such initiatives would be entirely dependent on the state of the economy and where consumer’s values lie.

The Wider Implications

With milk production shifting to larger farms, a range of both direct and indirect impacts are being felt across the country.

For example, milk production is now predominantly focused in fewer states such as California and Wisconsin, which together accounted for almost 33% of all U.S. milk production in 2018.

In larger farms, the herds are typically confined to tight spaces— rather than grazing in pastures—making animal welfare an issue for many of these farms. Concern over waste contamination and air pollution also brings the environmental sustainability of larger farms into question as they come under more pressure to reduce their impact on the planet.

Changing Tastes

Looking beyond the production of milk, changing consumer preferences could result in the most transformative effects on both large and small scale dairy farmers.

While rising populations are increasing the demand for dairy, per capita milk consumption declined by 24% between 2000 and 2017 in the United States. Consequently, the largest dairy producer in the country, Dean Foods, filed for bankruptcy in 2019, followed by another major milk producer, Borden Dairy, just two months later.

Experts claim that changing consumer preferences, along with competition from other beverage categories, are responsible for 90% of the total dairy decline.

No Country for Old Farms

The confluence of changing economics and an aging population of farmers has brought the U.S. dairy farming industry to a tipping point, and the near future is likely to bring a fresh wave of dairy farm closures.

I don’t see anything that would give them hope at this point. The best advice I can give to these folks, dairy farmers, is to sell out as fast as you can.

– Joe Schroeder, Farm Aid

As smaller farms continue to disappear from America’s rural landscape, the impacts of consolidation will not only affect dairy farmers, but entire rural communities too.

New Waves: The ESG Megatrend Meets Green Bonds

It’s clear that sustainable investing has been thrown into the limelight.

Increasingly, investors are seeing both the financial and social imperative for sustainable investing. In particular, the rapid growth of green bonds—a fixed income investment that is designed to raise funds for the climate or environment—is booming.

The above infographic from Raconteur navigates the growing green bond market against the backdrop of the broader ESG (environmental, social, and governance) investing shift.

Gathering Steam

By the end of 2020, $45 trillion in assets will adhere to sustainable practices, including ESG principles.

Despite the loss of confidence from COVID-19, investors flocked to sustainable-focused funds.In fact, global fund flows hit record levels for Q2 of 2020—surpassing $71 billion.

The fund flows are not without financial warrant. Between April 2015 and April 2019, average returns of socially responsible investments (SRI) outperformed their non-SRI peers. At the same time, 94% of sustainable indices realized stronger returns than their benchmarks between January and March 2020.

The accelerating demand for sustainable investments may seem like old news, but green bonds offer a new avenue.

What Are Green Bonds?

Green bonds raise money for climate and environmental projects, and are issued by governments, corporations, and financial institutions.

Multilateral development banks, which include the European Investment Bank and the World Bank, initially brought them to market in 2007, though they had a slow start. However, in 2019, new issues of green bonds topped $258 billion worldwide—jumping 51% in one year.

Across the green bond market there is a broad spectrum of different debt instruments. These include private placements, covered bonds, and green loans.

Green private placements occur when the sale of bonds are made to private investors, rather than through public offerings. Green covered bonds, on the other hand, are bonds that are backed by a group of assets that are sustainably-focused. Green loans are forms of loans that are meant to finance green projects.

Overall, green bonds can be diversified across a number of different sectors.

The Top Purposes for Green Bonds

What are the top sectors for green bond issuance?

Category20152019
Alternative energy$30.4B$143.8B
Green building$10.7B$63.5B
Sustainable transport$3.7B$58.7B
Energy efficiency$9.5B$47.6B
Sustainable water$3.1B$23.8B
Pollution prevention$1.4B$18.1B
Climate adaptation$1.8B$15.0B
Sustainable forestry/agriculture$1.1B$11.3B

Alternative energy, accounting for over $143 billion in green bonds, outpaces all other sectors by a wide margin. Within four years, renewable energy bond issuance has more than quadrupled.

Meanwhile, green building bonds are garnering attention. These instruments finance the construction of energy efficient buildings. Within the industry, a notable green building certification system is the LEED standard, also internationally recognized. Often, real estate investment trusts (REITs) are involved in issuing green building bonds.

Interestingly, Big Tech is also becoming more active within the green bond landscape. Google’s parent company, Alphabet, has issued a record $5.8 billion in corporate sustainability bonds to fund everything from energy efficiency projects to affordable housing.

The Top 10 Countries for Green Bonds

On a country-by-country level, green bonds are most common in the U.S., China, and France.

Germany issued its first multi-billion dollar government green bonds in just 2019. One catalyst behind this was the European Central Bank’s announcement that the environment would become a “mission critical” priority going forward.

This may contribute to the fact that both Germany and France saw the biggest change between 2018 and 2019.

Opening the Floodgates

As sustainable investing becomes front and center on the global agenda, questions about its impact on returns have arisen.

During times of both extreme exuberance and market crisis, companies with higher sustainability ratings have outperformed their respective benchmark. However, there is still a long way to go. Even with the record issuance of green bonds in 2019, they make up just 3% of all global bonds issued.

As demand for sustainable investments quickly grows, could it spell a watershed decade ahead for green bonds?
