Food Systems

With global population expected to reach 10 billion by 2050, the world’s ability to nourish its inhabitants is under threat if current trends continue.

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.

Even as the effects of the COVID-19 pandemic dissipate, the world continues to face a severe food security crisis, exacerbated by the ongoing Russia-Ukraine war, putting it further off track to achieve Sustainable Development Goal 2—ending hunger and malnutrition in all its forms by 2030.

For the fourth consecutive year, global acute food insecurity rose in 2022. As many as 205.1 million people across 45 countries and territories are in IPC Phase 3 (Crisis) or higher food insecurity as of September 2022, according to the Global Report on Food Crisis Mid-Year Update. That represents an increase of 29.5 million people from 2021.
