Millions of people suffer from food insecurity around the globe. With the help of Earth-observing satellites, the NASA-USAID SERVIR project is hoping to reduce that number.
Food security – the consistent availability and affordability of food – is a basic human need, yet it remains elusive for billions of people around the world. The United Nations’ 2021 State of Food Security and Nutrition in the World report, released in July, paints a grim picture of this reality: in 2020, nearly 1 in 3 people globally did not have enough to eat, up by more than 300 million people from the previous year.
The COVID-19 pandemic continues to disrupt food systems and supply chains on a global scale, but the heart of the problem – and the solutions to it – are far more diverse than any single factor. In Kenya, climate change, water shortages, and land degradation jeopardize crops and rangelands. In Southeast Asia, rising temperatures, increasingly variable weather, and low water levels along the Mekong River threaten livelihoods and food production. In Nepal, areas reliant on rain-fed agriculture are extremely susceptible to drought, a phenomenon becoming more frequent in an ever-warming climate.
