2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
A 15th century irrigation system is used on a small, intercropped and manured family orchard located in Valencia, in la Vall d’Albaida county (Spain)
2.2 Detailed description of the Technology
Description:
This technology is applied in a family orchard located in a small town (Bocairent) in Valencia, close to the Serra Mariola Natural Park. In the county of Vall d’Albaida, a 15th century system irrigates all the agricultural lands in the area. In this case study, the historical system has been used, since 1998, to irrigate a small plot of 0.2 ha. Water is diverted from the main water canal to a secondary channel which leads to the plot. Irrigation is applied when it is necessary, based on crop water requirements and the rainfall recorded. The original source of the water is the Serra Mariola range from where it flows into the Clarià river. Within the plot there are fruit trees as well as 5 subplots of 10 square meters (5 x 2m each). The subplots are used for vegetables (tomatoes, potatoes, fava beans, etc) under a rotational system (2 cycles per year). These 5 subplots are located between the rows of fruit trees (olives, almonds, figs, cherries, peaches), in an intercropping system. The whole field is fertilized annually with organic manure, which is stored at one end of the plot. This horse or sheep manure is acquired from a farm near the orchard. Pest control avoids artificial pesticides and fungicides: pests are controlled through encouraging natural predators. Weeds are removed by hand several times per season. The main purpose of this technology is the improvement of soil structure and organic matter content of the soil, while also preventing soil erosion caused by surface runoff. Avoiding pesticides and following an intercropping system gives multiple benefits: these include (a) maintaining biodiversity, (b) enhancing natural pollinators and pest predators, (c) respecting the Serra Mariola natural park, (d) improving ecosystem supporting services (nutrient cycling, soil formation, habitat provision, flood regulation) and regulating services (biological control pest and disease control), (d) creating pollination areas, and (e) encouraging carbon sequestration through permanent green cover in the intercropping system. Another benefit is the maintenance of cultural heritage: namely the 15th century, historically complex, irrigation system, which has been in use since being designed by Arabs up to the present day. Land users are continuously improving the technology by minimizing the impact on the agro-ecosystem through avoiding the use of pesticides. They are proud also with the improvement of the nutrient status of the soil, and the level of soil organic matter, achieved through the application of organic manure, as well as the intercropping and rotational system.
