Climate Change

This blog post is based on the T20 Policy Brief, "Environmental Sustainability of Food Systems, Global Food Security and Trade."

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.

Over the past two years, the impacts of ongoing regional conflicts, climate change, the COVID-19 pandemic, and the Russian-Ukraine war have drastically weakened the world’s already inadequate, unsustainable food systems. This confluence of factors has induced in supply chain disruptions and high and volatile prices for food, fertilizer, and fuel, and the result has been the third global food crisis in less than two decades.

It seems that joint food and energy crises have become the norm: Three have now occurred in just the last 15 years, driven by climate change and other human-made crises such as COVID-19 and the Russia-Ukraine war.

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.

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.
