Combining habitat requirements of endemic bird species and other ecosystem services may synergistically enhance conservation efforts

Analysis of Spatial and Temporal Characteristics and Spatial Flow Process of Soil Conservation Service in Jinghe Basin of China

The supply and demand of ecosystem services and their mutual feedback are important for the formulation of basin ecological environmental policies. Simulation of the spatial flow of ecosystem services can clarify the division of areas and can support policy development. This paper takes the Jinghe Basin in the Loess Plateau of China as the case-study area to simulate the spatial flow of soil conservation service on different scales. The results showed that (1) soil erosion situations in Jinghe Basin improved overall, with a trend of first aggravating and then recovering between 2005 and 2015; (2) the amount of annual soil conservation in the basin accounted for more than 75% of the potential soil erosion and showed a trend of first increasing and then decreasing; and (3) using digital elevation model (DEM) data and ArcGIS software, the experiment divided the basin into sub-basins (58 in total) and hydrological response units (HRUs) (e.g., 2181 HRUs in sub-basin #1), which were used to quantify the spatial flow direction and the corresponding amount of soil conservation service on the “HRU—river-sub-basin” scale. The divided supply and demand helped quantify the spatial flow pattern of soil conservation services from HRU to the sub-basin.

Assessing Ecosystem Services Supplied by Agroecosystems in Mediterranean Europe: A Literature Review

Agricultural landscapes in the Mediterranean region may be considered as social-ecological systems that are important for biodiversity conservation whilst contributing to a wide range of ecosystem services. This literature review aims to identify the current state and biases of ecosystem service assessment in agroecosystems within the Mediterranean region, evaluate pressures impacting on agroecosystems and their services, and practices that promote ecosystem service synergies in Mediterranean agroecosystems. A total of 41 papers were selected for analysis from a set of 573 potentially relevant papers. Most of the selected papers focused on supporting, regulating and provisioning services, and mostly assessed ecosystem structure or services in the European Mediterranean context. Literature about benefits and values ascribed to by communities and stakeholders remain limited. Results presented here support the notion of multifunctional Mediterranean agroecosystems and multiple synergies were recorded in this review. Publications dealing with pressures that related to agricultural practices and demographic changes were in the majority and impact on different cropping systems. This review highlights the need to carry out integrated ecosystem service assessments that consider the multiple benefits derived from agroecosystems and which may be used to identify management practices that lead to the improvement of ecosystem services capacities and flows.

Exploring the potential of vineyards for biodiversity conservation and delivery of biodiversity-mediated ecosystem services: A global-scale systematic review

Vineyards are experiencing strong expansion and management intensification worldwide, especially in areas with a Mediterranean climate, which are often characterized by a high conservation value. This is posing concerns about their environmental impact and it is fostering research on biodiversity patterns and ecosystem services in this agroecosystem. With this systematic review, we aim at providing a global and comprehensive overview of the current research on biodiversity and biodiversity-mediated ecosystem services in vineyards, considering the effects of landscape features and management practices. We carried out a systematic literature search on the Web of Science Core Collection database. Literature was filtered according to several criteria, resulting in a final collection of 218 papers published between 1995 and 2018 and referring to different organism groups (from microbes to vertebrates) and two spatial scales (local and landscape). The results of the studies are often contrasting and taxon- and scale-dependent, thus hindering conclusions at the global scale. However, at least three main points of practical relevance can be fixed: (i) organic viticulture weakly enhances biodiversity at the landscape scale, whereas contrasting effects have been found at the local scale; (ii) ground vegetation management by cover cropping and the conservation of native ground cover strongly promotes biodiversity; (iii) habitat heterogeneity at the landscape and local scales is a key element for biodiversity. Several studies support the view that promoting biodiversity in vineyard-dominated landscapes could also positively impact on several ecosystem services. Our study further revealed knowledge gaps that should be filled by future research. In particular, important geographical areas for wine production, as well as several organism groups, have been completely neglected. Studies at the landscape level are still scarce (specifically those addressing landscape configuration), and also the research about supporting, provisioning, and cultural biodiversity-mediated ecosystem services is still in its infancy.

Effects of vineyard soil management on the characteristics of soils and roots in the lower Oltrepò Apennines (Lombardy, Italy)

Cultivation of grapevines in sloping soils is very widespread all over the world, representing also fundamental branch of local economy of several hilly areas. Vineyards can be managed in different ways. Agronomical practices in inter-rows can be significantly different and may influence deeply the soil properties and the grapevine root development. Therefore, this paper aimed to analyze the effects of different management practices of inter-rows. We focused on the traditional agricultural techniques of tillage and permanent grass mulching as well as the alternation of these two practices between adjacent inter-rows, in terms of: i) soil physical properties; ii) soil hydrological properties; iii) root density; iv) root mechanical properties and root reinforcement; as well as v) biodiversity. The research was conducted in several test-sites of Oltrepò Pavese (Lombardy region, north-western Italy), one of the most important Italian zones for wine production in northern Italian Apennines. Among the examined soil properties, hydraulic conductivity was the most influenced soil property by different soil management practices. The absence of soil tillage allowed to increase superficial (first 0.2 m of soil) hydraulic conductivity, as a consequence of higher macroporosity and amount in organic matter. Vineyards with alternation management (grass mulching together with tillage) of inter-rows had the highest root density and the strongest root reinforcement, of up to 45% in comparison to permanent grass cover, and up to 67-73% in comparison to tilled vineyards. Soil microarthropod communities had more complexity where sustainable agricultural practices (permanent grass cover; alternation management of the inter-rows) were applied. The results of this study yielded important information to establish effective management practices of vineyards such as conserving organic matter and reducing slope instabilities by a better development of root apparatus in the soil.
