TLDR
In this article, the authors evaluated two agri-spillways (between 10 m and 15 m length, and slopes between 25.8° and 35°) by performing runoff experiments under extreme conditions (a motor driven pump that discharged water flows up to 1.33 l s-1 for 12 to 15 minutes: ≈1000 l).Abstract:
Suitable vineyard soils enhance soil stability and biodiversity which in turn protects roots against erosion and nutrient losses. There is a lack of information related to inexpensive and suitable methods and tools to protect the soil in Mediterranean sloping vineyards (>25° of slope inclination). In the vineyards of the Montes de Malaga (southern Spain), a sustainable land management practice that controls soil erosion is actually achieved by tilling rills in the down-slope direction to canalize water and sediments. Because of their design and use, we call them agri-spillways. In this research, we assessed two agri-spillways (between 10 m and 15 m length, and slopes between 25.8° and 35°) by performing runoff experiments under extreme conditions (a motor driven pump that discharged water flows up to 1.33 l s-1 for 12 to 15 minutes: ≈1000 l). The final results showed: i) a great capacity by these rills to canalize large amounts of water and sediments; and, ii) higher water flow speeds (between 0.16 m s-1 and 0.28 m s-1) and sediment concentration rates (up to 1538.6 g l-1) than typically found in other Mediterranean areas and land uses (such as badlands, rangelands or extensive crops of olives and almonds). The speed of water flow and the sediment concentration were much higher in the shorter and steeper rill. We concluded that agri-spillways, given correct planning and maintenance, can be a potential solution as an inexpensive method to protect the soil in sloping Mediterranean vineyards.read more

Erodibility prioritization of sub-watersheds using morphometric parameters analysis and its mapping: A comparison among TOPSIS, VIKOR, SAW, and CF multi-criteria decision making models.
TL;DR: Results showed that morphometric parameters have high efficiency in identification of erosion-prone areas and also VIKOR method has higher predictive accuracy than TOPSIS, SAW, and CF models.

An economic, perception and biophysical approach to the use of oat straw as mulch in Mediterranean rainfed agriculture land
TL;DR: In this article, the effect of the use of oat straw cover on soil erosion was investigated in the Sierra de Enguera region of Peru. And the results showed an immediate effect on the straw mulches as in these plots the runoff (from 7.7 till 5.9%) and soil erosion (from 47 till 26 Mg ǫ n−m−1 y−1 n−y−1) was reduced already in the first year.

Five decades of soil erosion research in "terroir". The State-of-the-Art
TL;DR: In this article, a review of the state-of-the-art work on soil erosion in vineyards is presented, concluding that soil erosion rates in vineyard are higher than those in other land uses and represents a worldwide threat to sustainability.

Gully erosion and environmental change: importance and research needs
TL;DR: In this article, the authors highlight the need for monitoring, experimental and modelling studies of gully erosion as a basis for predicting the effects of environmental change (climatic and land use changes) on gully degradation rates.

Climate Change and Global Wine Quality
TL;DR: This article showed that the impacts of climate change are not likely to be uniform across all varieties and regions, and that future climate change will exceed a threshold such that the ripening of balanced fruit required for existing varieties and wine styles will become progressively more difficult.

TL;DR: In this paper, an extensive database of short to medium-term erosion rates as measured on erosion plots in Europe under natural rainfall was compiled from the literature, and statistical analysis confirmed the dominant influence of land use and cover on soil erosion rates.

Loss-on-Ignition as an Estimate of Soil Organic Matter
TL;DR: In this article, loss on ignition at 430C of calcareous and non-calcareous soils has been compared with organic matter contents estimated by a wet oxidation method, and the presence of CaCO₃ did not affect the magnitude of the ignition loss and the gravimetric method provided both a reliable and simple estimation of soil organic matter.

Soil erodibility and processes of water erosion on hillslope
TL;DR: In this article, the authors focus on experimental research on rill and interrill erosion using simulated rainfall and recently developed techniques that provide data at appropriate temporal and spatial scales, essential for event-based soil erosion prediction.
