Arid regions are areas characterized by low rainfall, typically receiving less than 250 millimeters (10 inches) of precipitation annually. These environments often feature extreme temperatures, with hot days and cooler nights. Common landscapes in arid regions include deserts, such as the Sahara Desert and the Mojave Desert, where vegetation is sparse and adapted to survive with minimal water. The lack of moisture in arid regions affects both the ecosystem and human activities. Agriculture is challenging, requiring irrigation methods to support crops. Many communities in these areas rely on technologies like drip irrigation to conserve water and maximize agricultural output, ensuring food security despite harsh conditions.
