Currently, as a result of the Common Agricultural Policy actions, the use of cover crops for interrill erosion control is compulsory in olive groves located in hilly areas (mean slope > 10%) (Consejería de Agricultura, Pesca y Desarrollo Rural, 2015), and there is a notable rise of interest in gully erosion prevention derived from periodical wet cycles (e.g.…”

Concentrated flow erosion in Mediterranean cultivated areas is considered a major process of land degradation. Rills and ephemeral gullies in a 6.4 ha olive orchard catchment located in an intensive commercial farm, which could represent a common degradation scenario in hilly areas, were measured and compared with the sediment loads at the outlet. Four GPS survey campaigns were carried out between March 2009 and March 2014, for periods with cumulative precipitation ranging between 728 and 121 mm. Chopped pruning residues were kept on the lanes during campaigns 2–4, whereas a grass cover crop was seeded in campaign 4. Rainfall, runoff and sediment loads were measured in a flume gauge station at the catchment outlet. The ratio of concentrated flow erosion to catchment sediment load varied between 1.0 and 35.0. Total concentrated flow erosion ranged between 25.0 and 0.1 t ha−1. Rill erosion was the dominant process on ephemeral gullies for three campaigns, with a mean contribution to the total concentrated flow erosion of 55%. Rills clearly followed tractor tracks along the most parallel lanes to the maximum slope. Therefore, a change in traffic direction would be helpful to reduce the connectivity, controlled by the spatial distribution of rows and lanes in the farm. Olive plantation distributions should prioritize hydrological criteria to adapt traffic patterns in olive farms, as long as the tractor manoeuvrability and risk of overturning are not adversely affected. Although the farmer only kept the cover crop for one campaign, it proved to be an efficient measure for interrupting rills along the lanes, whereas pruning residues were effective for the control of interrill erosion. On‐site application of pruning residues reduced their handling and transport costs, while increasing the soil fertility and soil cover. However, guidelines for the efficient application of pruning residues are still necessary in terms of residue rates and orientation.

“…Worldwide soil degradation is another negative effect of agricultural intensification [4]. Sustainable management of agricultural soils and sustainable production are crucial to reverse the trend of soil degradation which could lead to the desertification of actively managed agricultural land [5,6]. The vegetative coverage found in orchards also protects the soil against erosion therein supporting long-term sustainability of the agricultural landscape [6].…”

The vegetative coverage found in orchards also protects the soil against erosion therein supporting long-term sustainability of the agricultural landscape [6]. One option to increase landscape diversity is to plant solitary trees or establish extensive orchards, which has been found to affect biodiversity (mainly of weed species) [7][8][9].…”

Extensive Orchards in the Agricultural Landscape: Effective Protection against Fraying Damage Caused by Roe Deer

et al. 2019

The objective of this research was to determine the efficiency of different types of protective barriers and how they protect against fraying damage in extensive fruit tree orchards. Orchards in open agricultural land are the target of fraying damage caused by roe deer (Capreolus capreolus L.). We assessed the effectiveness of four protective barriers: a rabbit-proof fence, a standard plastic tube commonly used in forestry, and an innovative plastic tube—variants with and without an additional rendering fat application. The study was situated in three extensive orchards in the southeastern part of Moravia in the Czech Republic. We analyzed the ratio of damaged trees, stem circumference damage, the length and height of damage on tree stems, the time periods with the most observed damage, and finally, the economic efficiency of each studied barrier. Most of the damage was observed in April and July. The most effective protective barrier was the innovative tube with rendering fat application (up to 100%) followed closely by the innovative tube without rendering fat application (95%). The standard plastic tube had an effectiveness of 49%, while the rabbit-proof fence was the least effective at 25%. In terms of the mean damage-lengths on tree stems, we found no significant differences between the rabbit-proof fence and the standard plastic tubes (21–22 cm). The usage of the innovative plastic tube without rendering fat reduced the average damage-length by half (10 cm) as compared to standard types (rabbit-proof fence, standard tube) of protection. The damage-heights on tree stems showed no significant differences among all variants (53–58 cm from the ground). Our analysis of economic parameters showed that rabbit-proof fencing had the worst cost efficiency, while the innovative tubes without rendering fat, had the best cost efficiency. We recommend starting the installation of protective barriers on trees in March, since we recorded relatively high activity of male roe deer in the following months.

Olive crops have become a strategic sector in Andalusia, Spain, providing an element of social cohesion and territorial management, but identified as vulnerable under climate change. Their great socioeconomic importance makes the mitigation of climate change effects an important strategy.The main contribution of this paper is to show the application of Bayesian networks into climate change assessment using the evaluation of its impact over olive system in Andalusia. Both classification and regression models were learnt and validated to predict the potential olive grove distribution under an Intergovernmental Panel on Climate Change scenario. A lower error rate was obtained for the regression problem compared to classification. Results predict that climate change will lead to changes into the territorial distribution of olive crops, with a movement from the river valley to the uplands due to the impact of the predicted increase in temperatures. Recommendations for Resource Managers• Bayesian networks are a powerful tool that allows dealing with both discrete and continuous data. However, if continuous data are available in order to retrieve all statistical information from them, discretization process should be avoided and original continuous data used for modeling purpose. • Olive cropping area follows an altitudinal gradient from the river bed to the mountainous ranges. The minimum temperature limits the establishment of this crop over certain altitude.
