In the latest The Lancet Planetary Health, Philip Thornton and Mario Herrero note how COVID-19 shows behavioral responses to global challenges can be both massive and rapid.

In response to the COVID-19 pandemic, governments have been taking a range of different measures, and at different speeds. Closing schools and workplaces, canceling public events, closing or severely curtailing public transport, putting hundreds of millions of people under lockdown, and imposing restrictions on domestic and international movement are only a few actions that have been taken.

To date, the amount spent by governments during 2020 is USD 8.4 trillion (as of April 22, 2020) — the vast majority of which is related to fiscal measures (94 percent%) and the rest spent on emergency investment in health services and vaccine development. Through a combination of sufficient determination and the speed of resource mobilization and the development of safety nets, major changes can be accomplished very quickly.

What About Investments For Climate Change Adaptation In Agriculture?

In 2018, the Global Commission on Adaptation (GCA) was set up to encourage measures to manage the effects of climate change through technology, planning, and investment. The GCA found that investing USD 1.8 trillion globally in five areas from 2020 to 2030 could generate USD 7.1 trillion in total net benefits.

In other words, failing to seize the economic benefits of climate adaptation with high-return investments would undermine trillions of dollars in potential growth and prosperity. The five areas considered for this estimate are early warning systems, climate-resilient infrastructure, improved dry-land agriculture crop production, global mangrove protection, and investments in making water resources more resilient.

Where There's A Will, There's A Way

For all we know, the Anthropocene might be an epoch rich in existential threats. Yet, governments have found USD 8 trillion to help combat the spread and effects of COVID-19 in just 10 weeks. Surely, governments can find USD 1.8 trillion in the coming decade to combat the effects of climate change on food and livelihood systems and the many hundreds of millions of highly susceptible people in lower-income and middle-income countries, while at the same time pursuing aggressive emission reductions to achieve the 1.5°C global warming goal. 

We should treat this situation with the same urgency as the COVID-19 pandemic — before we risk additional disruptions of incalculable magnitudes.
