In this day and age, this base instinct takes the form of a nation’s expenditures on armies and armaments, towards an end goal of global security and peacekeeping. This graphic from the Stockholm International Peace Research Institute (SIPRI) delves into the top military spenders as of 2019.

Top 10 Biggest Military Spenders

Let’s first take a look at the overall growth trends. The world’s military spending grew by 3.6% year-over-year (YoY)—currently the highest rate this decade—to surpass $1.9 trillion in 2019. While just 10 countries are responsible for nearly 75% of this amount, the U.S. alone made up the lion’s share with 38% of the global total. In fact, its YoY rise in spending alone of $49.2 billion rivals Germany’s entire spending for the same year. Naturally, many questions rise about where this money goes, including the inevitable surplus of military equipment, from night vision goggles to armored vehicles, that trickles down to law enforcement around the nation. Here’s how world’s top 10 military spenders compare against each other: China and India, currently embroiled in a border dispute, have upped the ante for military spending in Asia. India is also involved in clashes with its neighbor Pakistan for territorial claim over Kashmir—one of the most contested borders in the world. —Siemon T. Wezeman, SIPRI Senior Researcher Germany leads among the top spenders in terms of highest YoY military spending increases. According to SIPRI, this is a preemptive measure in the face of perceived growing Russian threats. These concerns may not be unfounded, considering that Russia comes in fourth for defense expenditures on the global stage—and budgets more towards military spending than any country in Europe, at 3.9% of its total GDP.

Military Spending as a Share of GDP

Looking more closely at the numbers, it’s clear that some nations place a higher value on defense than others. A country’s military expenses as a share of GDP is the most straightforward expression of this. How do the biggest spenders change when this measure is taken into consideration?

Eight of the 15 countries with the highest military spending as a percentage of GDP are concentrated in the Middle East, with an average allocation of 4.5% of a nation’s GDP. It’s worth noting that data is missing for various countries in the Middle East, such as Yemen, which has been mired in a civil war since 2011. While SIPRI estimates that combined military spending in the region fell by 7.5% in 2019, these significant data gaps mean that such estimates may not in fact line up with the reality. Explore the full data set of all available countries below. on After a year of casualties, structural devastation, and innumerable headlines, the conflict drags on. Many report the impacts to the economy, social demographics, and international relationships, but how do science and academia fair in the throes of war? Within the actions and responses of the conflict, we take a look at how six key scenarios globally shape science.

War’s Material Impacts to Science

1. Russia Invades Ukraine

The assault to research infrastructure in Ukraine is devastating. Approximately 27% of buildings are damaged or destroyed. The country’s leading scientific research centers, like the Kharkiv Institute of Physics and Technology, or the world’s largest decameter-wavelength radio telescope, are in ruins. While the majority of research centers remain standing, many are not operating. Amidst rolling blackouts and disruptions, a dramatic decrease in research funds (as large as 50%) has cut back scientific activity in the country. Rebuilding efforts are underway, but the extent to which it will return to its former capacity remains to be seen.

2. Ukraine Fights Back

As research funds have been redirected to the military, and scientists, too, have pivoted in a similar way. Martial law and general mobilization have enlisted male researchers, especially those with military experience and those within the 18-60 age range. Women were exempt until July 2022. Those with degrees in chemistry, biology, and telecommunications were required to enter the military registry. For both men and women researchers alike, these requirements meant staying in the country for the remainder of the year. Extensions for mobilization have subsided as of February 19th, 2023.

Social Impacts of War to Science

3. Western Leaders Exclude Russia

One year ago, scientists and institutions around the world immediately launched into protest against Russia’s escalation:

The European Commission agreed to cease payments to Russian participants and to not renew contract agreements for Horizon Europe The $300-million, MIT-led Skoltech program was dissolved one day after the war began, with no foreseeable restart in the future Various governments and research councils in the European Union froze collaborations and discouraged working with Russian institutions The European Organization for Nuclear Research, CERN, barred all Russian observers and will dismiss almost 8% of its workers—about 1,000 Russian scientists—hen contracts expire later this year

These condemnations, and more, remain in effect today and are emboldened by what has come to be known as a “scientific boycott”. Journal publishers around the world imposed some of their own sanctions on Russian institutions and scientists in light of this boycott. These range from prohibiting Russian manuscript submissions (Elsevier’s Journal of Molecular Structure) to scrubbing journal indices of Russian papers and authors.

4. Russia Dissociates from the West

As a response to the sanctions imposed on the Russian economy, Russia ceases to sell natural gas to most of Europe. Institutions are reassessing their usage and dependence on Russian energy, but alternatives are not yet affordable. The German Electron Synchrotron (DESY) in Hamburg, home to the world’s most powerful X-ray laser, is struggling with rising electricity costs. CERN, for instance, has already cut its data collection for the year by two weeks in order to save money. This makes it difficult for pre-war projects to continue collaborating with Russia. As a result, there are questions about how withdrawals may be affecting Russian science, too. For now, that remains relatively unknown, though some have guesses. Young scientists, many barred from attending international conferences and meetings, may seek employment or opportunity elsewhere to develop their careers. Some speculate a “brain drain” effect may occur, similar to the academic fallout of the Soviet Union’s collapse in the 1990s. How Russia will participate in pre-war international research collaborations is still unknown. For now, a number of pre-war projects ranging from the Arctic to the fire-prone wilds of northern Russia are on hold. All of these scenarios paint a concerning picture about the progress of research. There are indications that Russian scientific collaboration may already be shifting eastward.

Philanthropic Impacts of War to Science

5. New Homes for Ukrainian Science

Finding support for Ukrainians emigrating from the conflict is difficult, but not impossible. Though many Ukrainians scientists remain in the country making the best of a difficult situation, approximately 6,000 are now living abroad. Most Ukrainian emigrants are now living in Poland and Germany. Some scientists continue to work remotely, supporting projects at their home institutions or with new research programs they’ve found since relocating. These success stories are thanks to the work of a number of ad-hoc mobilizations that help keep researchers working in the European cooperation. Groups like MSC4Ukraine help postdoc students and researchers find new opportunities across Europe. Social media trends like #Science4Ukraine help connect researchers to other supportive movements.

6. The International Rebuilding of Ukrainian Science

Various research institutions have also lent support to the survival and rebuilding of science in Ukraine:

The largest science prize, the Breakthrough Prize, recently donated $3 million to fund research programs and reconstruction efforts Federal research councils, like those in Netherlands and Switzerland, also have programs to formally support displaced scientists and researchers The European Union is investigating new funding schemes that could repurpose almost €320 billion of frozen Russian Federal Reserves

No Consensus on Boycott

While the Western front seems united in it’s condemnation of the war, the international science community isn’t in total agreement with a science boycott. Some scientists argue that excluding Russian scientists—especially those who have vocalized their disdain for the war—serves to punish unrelated individuals. This fractures the benefits of international scientific exchange. Others, especially those in countries who are economically dependent on Russia, have remained silent or even supported the invasion. In these cases, Russia’s science initiatives may lean more heavily in their direction. It’s easy to appreciate how war complicates many different angles of the global research ecosystem. After one year, how things will turn out remains a mystery. But one thing is for certain: science adapts and progresses even in the bleakest times. For now, supporting all efforts to reduce conflict remains in science’s best interests. Full sources here
