What's New

With global temperatures already 1.2 degrees Celsius above pre-industrial levels, climate change is having major impacts on agriculture that fall disproportionately on the Global South—from crops, to livestock, to aquaculture. Agricultural systems endure frequent heat waves, flooding, and drought—often all in one season. Climate-related extreme weather events such as intense rainstorms pose a serious threat to crops.

Recent shocks from the COVID-19 pandemic to the ongoing Russia-Ukraine war have disrupted global food and fertilizer supply chains—causing price spikes and increased price volatility—a disastrous combination for many vulnerable consumers around the world.

The FAO Food Price Index rose by nearly 1 percent in May due to increased cereal and dairy prices. It remained 3.4 percent below its May 2023 levels and nearly 25 percent below the peak seen in March 2022.

The world’s food security challenges are becoming increasingly complex. In many countries, populations now face a double burden of malnutrition: both undernutrition and micronutrient deficiencies and overweight/obesity and diet-related non-communicable diseases (NCDs). These burdens are being further exacerbated by the strain placed by climate change on food supplies and nutritional content.

The impacts of our diets extend well beyond mealtime to affect our health and well-being. Unhealthy diets underpin many public health challenges, including all forms of malnutrition and diet-related noncommunicable diseases (NCDs). Many countries are facing a double burden of malnutrition—meaning that undernutrition and micronutrient deficiencies coexist with overweight and obesity, or diet-related NCDs. Unhealthy diets are the leading risk factor for NCDs, which are responsible for more than 73% of deaths globally.
