Denise Garcia (Northeastern University, Boston, Mass) is an academic who advises the United Nations on arms control and the military uses of artificial intelligence and robotics. Highlights from her article, Redirect military budgets to tackle climate change and pandemics follow.
She opens: “The old world order, in which governments build arsenals to protect the state, is clearly not delivering what people need. According to the Global Peace Index, levels of peace have fallen by 2.5% since 2008. The index measures 23 indicators — including military expenditure and ease of access to small weapons — in 163 independent states and territories, ranking them according to their level of peacefulness. The drop in peace levels is despite an increase in military spending globally, to a record US$1.9 trillion in 2019”.
Despite threats to human existence from climate change, biodiversity loss and a pandemic that’s devastating economies and paralysing societies, countries still spend recklessly on destructive weapons for wars they will never fight.
Some nations, including Iceland and Costa Rica, don’t have armies. This year, Costa Rica became one of the first countries to have stopped and then reversed deforestation, with a goal of becoming carbon neutral; it is also one of the first to adopt a tropical carbon tax.
To recover from the costs of the pandemic, estimated at up to $82 trillion over the next 5 years (see go.nature.com/2q5jtyf), governments should focus their spending on stimulus packages for decarbonization, health, education and the environment.
The arms trade is lucrative: sales by the world’s leading arms-producing companies reached $420 billion in 2018. Everything from small arms, tanks and aircraft to military goods and services are sold in legal and illegal markets. They end up on the streets and in the hands of militant organizations such as Al-Qaeda. The result? In 2017 (the latest year for which data are available), some 464,000 people died in 2017 through homicides, and 89,000 individuals died in armed conflicts globally.
The five countries with the largest defence budgets, unprepared for Covid, were hit hard
The United States, China, India, Russia and Saudi Arabia together accounted for almost two-thirds (62%) of global military expenditure in 2019, and US, Indian and Russian rates of infection are some of the highest so far, with the United States topping both lists. Their arms were no defence against Covid. Germany and New Zealand spend around 1% of GDP and have so far fared much better in the pandemic.
By 2050, almost 100 million people could be forced to migrate from coastal areas and other places that will become uninhabitable as a result of climate change (see go.nature.com/3agzsij).
In 2019, fires in the Amazon rainforest raged towards the ‘point of no return’ at which the whole forest ecosystem could collapse. The Amazon is the largest reservoir of biodiversity on Earth; in economic and social terms, from food to jobs, homes and health, its loss has been put at about $3.6 trillion. Biodiversity loss also exposes people to new viruses.
The real enemy is upon us. The frequency of heatwaves, droughts, forest fires, floods and hurricanes has quadrupled over the past four decades, and is rising. All of these call for approaches to national defence that are genuinely centred around human security.
Professor Garcia has long argued that nations should prioritize ‘human security for the common good’ over military spending, ensuring people can live to their full potential – and that governments need to accept that their concept of national security sustained by a military–industrial complex is anachronistic and irrelevant.
