Rainwater is a valuable local resource that can be captured and reused to support irrigation and improve water availability in agriculture. Roof-based rainwater harvesting systems collect runoff from farm buildings, greenhouses, and storage halls and store it in tanks for later irrigation use, helping buffer rainfall and reduce pressure on groundwater and surface water sources. Beyond roofs, landscape-shaping measures such as field-side ditches, terraces, retention ponds, and micro-catchment systems capture runoff directly in fields and orchards, slow water flow, and enhance infiltration and water availability in the root zone.

Within GEORGIA, these technical and nature-based approaches are combined to reduce runoff losses, limit erosion, and strengthen drought resilience across different farming systems.
