How Vertical Farming Works
By 2050, there will be 3 billion more people in existence, and close to 80% of the world’s population will live in urban areas. The demand for food will be unprecedented, and we will need to figure out how to get food to the cities in the most effective way.
Enter vertical farming – the idea of building entire skyscrapers occupied with vertically-stacked farms that produce crops twice as fast, while using 40% less power, having 80% less food waste, and using 99% less water than outdoor fields.
Is it feasible, or is it a futuristic money pit?
The Advantages of Vertical Farming
There’s no question that vertical farming has enticing potential benefits.
The first is yield. Vertical farming can produce crops year-round, which increases production efficiency by a multiplier of 4 to 6 depending on the crop. There would also be less wastage and spoilage, as most of the crops could be sold fresh in a market or restaurant from the same facility. It’s estimated that 30% of harvested crops today are lost due to spoilage or infestation.
Secondly, vertical farming has less risk associated with it. Big weather events such as floods, droughts, or storms can put a dent into agricultural activity fast, costing farmers billions of dollars. Farming indoors can reduce the risk of these types of events to as low as possible.
Lastly, vertical farming is inherently more sustainable. By stacking farms vertically, the productivity per unit of land can be many times higher and arable land can be saved for other purposes. Further, there are no transportation costs to get the crops to market, and energy and water can be recycled within the building. Methane digesters can even help convert organic waste to energy to help power the building.
On paper, vertical farming seems to have big advantages.
Too Good to be True?
Critics of vertical farming question the potential profitability of commercial operations.
They say the capital expenditures, as well as the additional energy costs for lighting and heating, could outweigh any benefits. Building complex plumbing and elevator systems to distribute food and water throughout a 30-story building is not easy.
Meanwhile, for traditional farming operations, both sunlight and heat are free. Irrigation is generally cheap as well.
The benefits of vertically-stacked farms would have to outweigh the increased costs. With billions of new people being added to cities over the next decades, this could come be sooner than later.

Mapped: The Anatomy of Land Use in America
The U.S. covers an immense 3.8 million square miles—what is all this land currently used for, and what does that mean for the future?
Mapped: The Anatomy of Land Use in America
The United States is not just an economic and political giant on the global stage—the country also has one of the largest land masses at its disposal.
Altogether, the country spans 3.8 million square miles (9.8 million km²)—making it the third largest country in the world. Even without factoring Alaska and Hawaii into the calculations, the contiguous U.S. land mass can fit up to 30 European countries within it.
With this much ground to work with, it raises the natural question of how land actually gets used by America’s economy. For example, what percentage of land is taken up by urban areas, and how much farmland and forests exist in comparison?
Today’s maps from the McHarg Center put America’s wide variety of land uses into perspective.
The Components of U.S. Land Use
As the U.S. prepares to add 100 million more people this century, the “2100 Project: An Atlas for the Green New Deal” provides a snapshot of U.S. land use (as of 2017), aimed at managing resources to support this future.
According to this data, here is a snapshot of land use in the Lower 48 States:
|Land type||Land use (%)||Land area|
|Grasslands and Pasture||17%||530,400 mi²|
|Open Space||3%||93,600 mi²|
|Urban Areas||2%||63,400 mi²|
Let’s dive into the specifics of three types of land: urban areas, forests, and agriculture.

Small But Mighty: U.S. Urban Areas
It’s clear that even a little space goes a long way. Although urban areas take up only 2% of land, an overwhelming majority of Americans call cities their home. As of 2018, urbanites made up over 82% of the U.S. population.
Where people go, productivity often follows. In 2018, it’s estimated that 31 county economies made up a whopping 32% of national GDP. Most of these counties were located in and around major cities, such as Los Angeles or New York.
Although urban areas are a small part of the overall land they’re built on, they’re integral to the nation’s continued growth. According to research by the McKinsey Global Institute, it’s estimated that by 2030, 60% of job growth could come from just 25 hubs.
Seeing Green: America’s Vast Forests
On the flipside, forests account for over a quarter of land in the U.S., divided almost evenly between deciduous and evergreen trees. Many protected national and state parks can also be found in and around forests.
On the mainland, California and Oregon are the states with the most forested land—unfortunately, they have also been plagued by wildfires in recent, dry summer months.
Wetlands are also included in the map above, particularly around the southern tip of Florida, where Everglades National Park is located. Over the years, many wetlands were drained to make way for agriculture, particularly in the Great Lakes megaregion. As a result, it’s estimated that their area today is only half of what they once used to be.
Home Grown: Agriculture in the U.S.
Last but not least, the final set of maps show where America grows its food. Agricultural, food, and related industries contributed $1.05 trillion (5.4%) to U.S. GDP in 2017.
Wheat, corn, and soybeans are the major crops grown in the U.S.—and cotton also makes the cut as a profitable non-food crop. Much of these crops feed not only Americans, but other parts of the world too. Soybeans, corn, and wheat are exported across the Pacific mainly to China and Japan.
Corn, in particular, is a unique crop with a myriad of uses, from food to fuels. Up to 40% of U.S. corn is turned into livestock feed, with cows consuming over half (56%) of this amount.
Although fewer American consumers are opting for meat in their diets, production has remained at high rates. Further, as incomes continues to increase worldwide, the global appetite for meat is set to rise along with it.
Future Land Use
The U.S. population is set to grow by 100 million more people over the coming decades, raising the pressure on limited U.S. land and natural resources. This pressure will be felt everywhere, from dense urban land to agricultural farmland.
How the land gets utilized will shape the country’s future for years to come.
An Investing Megatrend: How Climate Change and Resource Scarcity are Shaping the Future
Learn how climate change and resource scarcity are affecting our most basic needs, and how investors can take advantage of this growing megatrend.
If you’ve ever played with dominos, you’re familiar with their cascading effects. Gently nudge one piece, and the force will ripple throughout the rest.
This process of cause and effect works much the same way in society and business: as global forces take hold, their effects are deeply intertwined with the financial markets.
The Climate Megatrend
Today’s infographic comes from BlackRock, and it explains how one such megatrend, climate change and resource scarcity, will be a long-term opportunity for investors.
Earth in the Hot Seat
In 2018, global CO2 emissions rose 1.7% to the highest level since 2013. These rising emissions have intensified the effects of climate change, with 2015-2018 being the four hottest years ever recorded. Society and the economy are starting to feel its negative consequences:
- Extreme weather events have become more frequent. In particular, floods and other hydrological events have quadrupled since 1980.
- In hotter, wetter conditions, infectious diseases spread more easily—between 2004-2017, total tick-borne illnesses increased by 163%.
- The global insured losses from natural catastrophes was $79 billion in 2018.
- Extreme weather effects, and the health impact of burning fossil fuels, cost the U.S. economy at least $240 billion in 2018.
It’s clear that climate change is having an immediate, serious impact on the world.
Many see climate change as a long-dated future risk, however, our research findings show that compared to the 1980’s, there are measurable GDP impacts in the market today
-Brian Deese, Global Head of Sustainable Investing at BlackRock
In addition to these issues, climate change is contributing to another problem: it’s becoming harder to feed the global population.
Over 7 Billion Mouths to Feed
Climate change significantly threatens global food security. As glaciers melt, the world’s freshwater supply—including what’s available for food production—melts with it. This is a significant problem, considering that between 2,000-5,000 liters of fresh water are needed to produce one person’s daily food intake.
As an added hurdle to food production, supply and demand are pulling in opposite directions.
The share of total employment in agriculture has dropped significantly over time. Even worse, among the food that is able to be harvested, roughly 30% is lost or wasted globally.
On top of limited resources, the world will have to contend with forces driving up food demand.
- Population growth: By 2050, the global population will grow by about two billion.
- More calorie-rich diets: As emerging economies grow their wealth, their populations seek richer foods like meat and dairy products.
How can society combat these pressing issues?
A Greener, More Plentiful Future
As society works to slow climate change and produce more with less, a myriad of investment opportunities will emerge.
- Renewable energies are becoming increasingly competitive.
- Electric & fuel cell vehicles are growing in market share.
- Products made from recycled materials are appealing to environmentally-conscious consumers.
- Agricultural machinery counters the declining workforce and increases productivity.
- Precision agriculture leverages real-time environmental data to help farmers make decisions.
Climate change and resource scarcity will be a driving force behind the actions of consumers, companies, and governments for years to come.
By staying attuned to this megatrend, investors will be able to spot long-term opportunities.
