Desertification is a global issue that affects millions of people worldwide. As the climate changes, dryland areas are becoming increasingly vulnerable to land degradation and desertification, leading to decreased crop yields and environmental degradation. To combat this problem, we need to adopt sustainable management practices that protect our land resources and ensure that dryland areas remain productive and resilient.
