摘要

Aside from its key role in food production, agriculture is often associated with runoff, sediment, and nutrient losses. At the same time, agriculture is exceptionally adaptable. It can be adjusted seasonally—including its functionality to retain water in the landscape. Austrian agriculture largely depends on precipitation; too little or too much rain affects both crop production and soil health, as well as the soil’s ability to retain, store, and release water. Surface runoff results from the interaction of heavy rainfall, soil properties and changing soil conditions, terrain, as well as, significantly, land cover and land management. Heavy rainfall dominates the immediate runoff response. As a result of climate change, short, convective events are expected to become more intense, as a warmer atmosphere can absorb and release more water; seasonal patterns of vegetation cover will also change, and with them, the periods during which soil surfaces are exposed.

This work focuses on in-situ approaches retaining water on-site—in the field—rather than in the downstream areas. In-situ retention measures are driven by two complementary approaches: (i) improving and maintaining soil health and functionality to capture water, allow it to infiltrate, store it in the soil, and release it; and (ii) seasonal and small-scale in-situ water harvesting measures that retain surface runoff and store it in the soil profile. Long-term field trials underscore the success of these landscape water management measures, which demonstrate their impressive capacity in integrated combinations at the watershed level.
