How can rain-fed crops grow without rain? That is the question facing farmers in water-stressed regions where rising temperatures, prolonged periods of drought and other impacts of climate change threaten food security and livelihoods.

According to the Food and Agriculture Organization of the United Nations (FAO), climate solutions hold answers to tackling water scarcity and increasing food production in a sustainable way.

Here are three ways FAO-led Green Climate Fund (GCF) projects are helping farmers adapt to climate change in water-stressed regions with agroforestry systems in El Salvador, rooftop rainwater harvesting in Jordan, and digital tools in Pakistan.
