1) The document describes a study evaluating sustainable land management techniques at a farm in semi-arid southeast Spain, including green manure, reduced tillage, water harvesting systems, mulching, and reduced tillage for cereals. 2) Preliminary results show that water harvesting increases soil water content and almond yields, while green manure also increases almond yields and reduces soil and water loss compared to conventional practices. 3) Final conclusions on the effects of these techniques on sediment yields are uncertain due to challenges calculating runoff contribution areas from laser scan data. Mulching also did not clearly improve outcomes so far.
