Land-Use Impacts on Ecosystem Services Provisioning in Massachusetts 2001-2011
Meeting fundamental human needs while also maintaining ecosystem function and services is the central challenge of sustainability science. In the densely populated state of Massachusetts, USA, abundant forests and other natural land cover convey a range of ecosystem services. However, after more than a century of reforestation following an agrarian past, Massachusetts is again losing forests, this time to housing and commercial development. We used land-cover maps, ecosystem process models, and land-use data bases to map changes (2001, 2006, 2011) in eight ecosystem service variables and to identify “hotspots,” or areas that produce a high value of five or more services, at three policy-relevant spatial scales. Water-related services (clean water provisioning and flood regulation) experienced local declines in response to shifting land uses, but changed little when measured at the state-level. General habitat quality for terrestrial species declined state-wide during the study period as a consequence of forest loss. In contrast, climate regulation (carbon storage) and cultural services (outdoor recreation) increased, driven by continued forest biomass accrual and land protection, respectively. Timber harvest volume had high inter-annual variability, but no temporal trend. The scale at which hotspots are delineated greatly affects their quantity and spatial configuration, with a higher density in eastern Massachusetts and 10–12% more hotspots overall when they are identified at a town scale as compared to a watershed or state scale. Ecosystem service hotspots cover a small percentage of land area in Massachusetts (2.5–3.5% of the state), but are becoming more abundant as urbanization concentrates ecosystem service provisioning onto a diminished natural land base. This suggests that while ecosystem service hotspots are valuable targets for conservation, more are not necessarily better since hotspot proliferation can reflect the bifurcation of the landscape into servic
Assessing the Provision of a Multi-Ancillary Service Framework provided by PV-BES Systems (ProMiSe) - LAB Experiments
<p>This dataset comprises the results obtained during ProMiSe project. In particular, scope of ProMiSe is to test and validate a new unified control architecture used to overcome voltage violations and voltage unbalance issues by conducting real-time simulations and utilizing a power hardware-in-the-loop platform. The validation scheme reflects a range of different scenarios and realistic test cases of integration of the unified control strategy in modern distribution networks. In particular, three experiments are considered:</p> <p>- <strong>Experiment 1</strong>: The performance of the proposed unified strategy is evaluated in a low-voltage (LV) distribution network (DN). The LV DN, the detailed model of a three-phase, four-leg converter (3Ph4LC) and the deployed voltage regulation (VR) / voltage unbalance mitigation (VUM) algorithms are developed in the real time digital simulator (RTDS).</p> <p>- <strong>Experiment 2</strong>: The performance of the proposed unified strategy is evaluated in the LV DN of Experiment 1. The LV DN, the detailed model of a 3Ph4LC and the deployed VR/VUMalgorithms are developed in the RTDS. Compared to Experiment 1, in Experiment 2 the line <em>R/X</em> ratio is decreased, in order to demonstrate the impact of the <em>R/X</em> on the provided ancillary services. Here, it should be highlighted that grid voltage levels as well as the power levels of load nodes have been properly readjusted to achieve similar voltage levels to the point of the inter-connection (POI) of the 3Ph4LC with Experiment 1. </p> <p>- <strong>Experiment 3</strong>: The performance of the proposed unified strategy is evaluated in the LV DN of Experiment 1. The LV DN and the VR/VUM algorithms are developed in the RTDS. Compared to Experiment 1, in Experiment 3 the detailed model of the ProMiSe 3Ph4LC has been replaced with controllable current sources. Note that the filter has been remained in the analysis. Here, it should be highlighted that grid voltage levels have been properly readjusted to achieve similar voltage levels to POI with Experiment 1. In addition, due to a resonance problem observed during the test between the lab equipment and the virtual network in the software platform, the filter parameters are readjusted to overcome the problem.</p> <p>For each experiment, the obtained results are provided in csv format.</p> <p>For more Information regarding the ProMiSe project, the conducted simulations, as well as the files/variables expanation, please refer to ProMiSe-Info.pdf.</p>

Climate change threatens the distribution of major woody species and ecosystem services provision in southern Africa
<p>Species occurrence points used in this study to investigate the effect of climate change on the distribution of eight tree species in 18 countries in southern Africa, covering 36% of the continent. We proposed a loser/winner ranking of the species based on the changes in climatic suitability within their historical distributions as well as future gains and losses of suitable areas. We interpreted these findings in terms of changes in the provision of key ES (timber, food, energy, and medicine), and identified hotspots of ES provision decline. We used species presence data from the Global Biodiversity Information Facility, climatic data from the AfriClim dataset, and the MaXent algorithm to project the changes in species' land suitability. </p>

Data from: Effect of management on natural capital stocks underlying ecosystem service provision: a 'provider group' approach
Land management practices directly impact on the occurrence and condition of natural capital stocks, which can be measured using species diversity and abundance metrics. Species identity and abundance drive ecosystem service supply, either through effects of local diversity and/or through the presence of service providing species. However, the influence of management practices on the provision of ecosystem services is not adequately understood. We grouped grassland plant species into six groups according to desirable attributes (palatability and nutritional value to livestock; medicinal or aromatic compounds; nectar production; pollen production; nitrogen fixation; and endemic and red listed species), which we recognise as ecosystem service 'provider groups', and tested the influence of three land management practices (abandonment of mowing, grazing, and mowing) on diversity and abundance within these groups in upland temperate grasslands of Transylvania (Romania). All three management practices favoured at least one provider group, but hay making in upland grasslands favoured more provider groups than abandonment of mowing or grazing. The effects of management on diversity and abundance within several provider groups diverged from the effects on overall species diversity and abundance. Management, through changes in species composition, favours certain provider groups, and hence ecosystem services, over others. The provider group approach is more useful than overall species diversity metrics for assessing the provision of ecosystem services from landscapes and can be used to inform the development of agri-environment schemes and conservation policies aimed at meeting priorities for ecosystem service provision.
Data from: Modest enhancements to conventional grassland diversity improve the provision of pollination services
1. Grassland for livestock production is a major form of land use throughout Europe and its intensive management threatens biodiversity and ecosystem functioning in agricultural landscapes. Modest increases to conventional grassland biodiversity could have considerable positive impacts on the provision of ecosystem services, such as pollination, to surrounding habitats. 2. Using a field-scale experiment in which grassland seed mixes and sward management were manipulated, complemented by surveys on working farms and phytometer experiments, the impact of conventional grassland diversity and management on the functional diversity and ecosystem service provision of pollinator communities were investigated. 3. Increasing plant richness, by the addition of both legumes and forbs, was associated with significant enhancements in the functional diversity of grassland pollinator communities. This was associated with increased temporal stability of flower–visitor interactions at the community-level. Visitation networks revealed pasture species Taraxacum sp. (Wigg.) and Cirsium arvense (Scop.) to have the highest pollinator visitation frequency and richness. 4. Increased sward richness was associated with an increase in the pollination of two phytometer species; Fragaria × ananassa and Silene dioica, but not Vicia faba. Enhanced functional diversity, richness and abundance of the pollinator communities associated with more diverse neighbouring pastures were found to be potential mechanisms for improved pollination. 5. Synthesis and applications. A modest increase in conventional grassland plant diversity with legumes and forbs, achievable with the expertise and resources available to most grassland farmers, could enhance pollinator functional diversity, richness and abundance. Moreover, our results suggest that this could improve pollination services and consequently surrounding crop yields (e.g. strawberry) in agro-ecosystems.

Evidence of time-lag in the provision of ecosystem services by tropical regenerating forests to coffee yields
<p>Abstract Restoration of native tropical forests is crucial for protecting biodiversity and ecosystem functions, such as carbon stock capacity. However, little is known about the contribution of early stages of forest regeneration to crop productivity through the enhancement of ecosystem services, such as crop pollination and pest control. Using data from 610 municipalities along the Brazilian Atlantic Forest (30 m spatial resolution), we evaluated if young regenerating forests (less than 20 years old) are positively associated with coffee yield and whether such a relationship depends on the amount of preserved forest in the surroundings of the coffee fields. We found that regenerating forest alone was not associated with variations in coffee yields. However, the presence of young regenerating forest (within a 500 m buffer) was positively related to higher coffee yields when the amount of preserved forest in a 2 km buffer is above a 20% threshold cover. These results further reinforce that regional coffee yields are influenced by changes in biodiversity-mediated ecosystem services, which are explained by the amount of mature forest in the surrounding of coffee fields. We argue that while regenerating fragments may contribute to increased connectivity between remnants of forest fragments and crop fields in landscapes with a minimum amount of forest (20%), older preserved forests (more than 20 years) are essential for sustaining pollinator and pest enemy's populations. These results highlight the potential time lag of at least 20 years of regenerating forests' in contributing to the provision of ecosystem services that affect coffee yields (e.g., pollination and pest control). We emphasize the need to implement public policies that promote ecosystem restoration and ensure the permanence of these new forests over time.</p>
