With climate change impacts, deforestation, and land use changes accelerating around the world, the need for mapping croplands—which cover 1.2 billion hectares, approximately 12% of Earth’s surface—is growing more urgent.

Two years after Russia launched its full-scale invasion of Ukraine on February 24, 2022, the war continues to disrupt agricultural production and trade in Ukraine—one of the world's largest agricultural exporters—and poses an ongoing threat to global food security. Yet global commodity markets have adjusted to these disruptions, in part to due to increased exports by other suppliers, including Russia, easing the initial shock.

Over the past three decades, the world lost as much as $3.8 trillion in agricultural products as a result of disaster events, according to a new flagship report from the UN Food and Agriculture Organization. That equates to a loss of around 5 percent of global agricultural GDP per year and has serious implications for food security, agricultural livelihoods, and the sustainability of the global agrifood system.

Despite the inconclusive outcome on the COP27 Sharm El-Sheikh Implementation Plan in Dubai, COP28 has nonetheless been hailed for putting a much needed and strong focus on food systems, which are simultaneously threatened by and contribute to climate change.

IFPRI participated in COP28 in late 2023 as part of a wider CGIAR delegation. Following on CGIAR’s five key takeaways from the global climate conference, this blog post—written by IFPRI Communications and Public Affairs Director Charlotte Hebebrand with input from IFPRI research units—reflects on the significance of the COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action through a policy lens.
