Rainwater Harvesting Boosts Rainfed Agriculture in Tunisia

Strengthening rainwater harvesting in Tunisia enhances sustainable rainfed agriculture on smallholdings. Traditional techniques like 'jars' and runoff collection basins improve water retention in arid and semi-arid regions with annual rainfall below 300 mm. These methods reduce soil erosion, preserve nutrients, and mitigate drought risks during critical crop growth phases. Rainwater harvesting is a key adaptation strategy for climate resilience, offering significant potential to combat desertification and support food security in water-scarce environments.
