From Food Shortage to Security: A PhD Student's Journey and Research

BGU PhD student David Samson Isaka shares his powerful personal experience of the climate crisis, explaining how he has witnessed his community's water sources and native plant species vanish, forcing families to walk kilometers to fetch water. He discusses how this reality drives his research in plant physiology, where he studies how crops like sweet potatoes can develop a natural stress tolerance mechanism, becoming sweeter and stronger under the drought and nitrogen limitations that are "imminent" in our changing climate. Ultimately, David’s work focuses on a critical goal: helping farmers use methods like regenerative agriculture to achieve global food security despite the warming world.
