As the world grapples with the increasing impacts of climate change, global policymakers need to take much stronger action to reduce the emission of greenhouse gases (GHG). This is the message from the recent UN Environment Programme’s Emissions Gap Report 2022. The report provides the stark conclusion that current national climate change pledges can only limit global warming rises by 2.4-2.6°C by the end of the century – far from the 1.5°C goal set forth by the Paris Agreement. To stand a chance of reaching that ambitious goal, global GHG emissions need to be cut by 45 percent by 2030.

Mitigating climate change and the degradation of natural resources while increasing the production of safe and nutritious food to eradicate hunger and ensure food security for a rapidly growing population is the most important and urgent challenge facing humanity today.

The sanctions imposed by the European Union, United States, Canada, and other countries on Russia and Belarus following Russia’s February 24 invasion of Ukraine included restrictions on banking, trade, technology transfers, and specific individuals. These came on top of earlier sanctions on both countries – on Russia, in response to its 2014 annexation of Crimea, and on Belarus, in response to human rights violations in 2020 and its forced grounding of Ryanair flight 4798 to seize a dissident journalist in 2021.

Climate change poses a growing threat to efforts to build sustainable food systems. The COVID-19 pandemic and the current Ukraine crisis have further exacerbated global food and nutrition insecurity, leading to significant increases in poverty, hunger, and malnutrition. A July 18 launch event for IFPRI’s 2022 Global Food Policy Report (GFPR) in Kathmandu, Nepal, explored the potential for more effective policies and programs focused on climate impacts and food systems.

In 2021, the United Nations Intergovernmental Panel on Climate Change sounded the alarm on a looming crisis: Climate change is generating a “code red for humanity” that requires urgent action. Food systems are deeply entwined with this crisis. In many regions, especially in the developing world, climate change has already started to reduce agricultural productivity and disrupt supply chains, putting pressure on livelihoods and threatening to significantly increase hunger and malnutrition, making adaptation efforts crucially important.
