Interannual variation in land-use intensity enhances grassland multidiversity
- 2014

In: Proceedings of the National Academy of Sciences. - : Proceedings of the National Academy of Sciences. - 1091-6490 .- 0027-8424. ; 111:1, s. 308-313

Journal article (peer-reviewed)abstract
- Although temporal heterogeneity is a well-accepted driver of biodiversity, effects of interannual variation in land-use intensity (LUI) have not been addressed yet. Additionally, responses to land use can differ greatly among different organisms; therefore, overall effects of land-use on total local biodiversity are hardly known. To test for effects of LUI (quantified as the combined intensity of fertilization, grazing, and mowing) and interannual variation in LUI (SD in LUI across time), we introduce a unique measure of whole-ecosystem biodiversity, multidiversity. This synthesizes individual diversity measures across up to 49 taxonomic groups of plants, animals, fungi, and bacteria from 150 grasslands. Multidiversity declined with increasing LUI among grasslands, particularly for rarer species and aboveground organisms, whereas common species and belowground groups were less sensitive. However, a high level of interannual variation in LUI increased overall multidiversity at low LUI and was even more beneficial for rarer species because it slowed the rate at which the multidiversity of rare species declined with increasing LUI. In more intensively managed grasslands, the diversity of rarer species was, on average, 18% of the maximum diversity across all grasslands when LUI was static over time but increased to 31% of the maximum when LUI changed maximally over time. In addition to decreasing overall LUI, we suggest varying LUI across years as a complementary strategy to promote biodiversity conservation.

Guidelines for good practice on voltage quality monitoring
- 2013
-
In: 22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013). - Red Hook, NY : Curran Associates, Inc.. - 9781849197328
-
Conference paper (peer-reviewed)abstract
- Guidelines are given for setting up and running a voltage quality monitoring programme. These guidelines are published jointly by CEER and ECRB and contain among others recommendations on the number and location of monitors, on disturbances to be monitored and indices to be calculated, on reporting of the results and on financing of the programme. It is concluded that voltage quality monitoring programs are important tools for voltage quality regulation and that all other possible applications should be kept in mind when setting up such a programme. It is also concluded that such programmes should be funded through the network tariffs; that the results should be made available regularly and that diversification of indices and methods is to be avoided.

Non-thermal production of pure hydrogen from biomass: HYVOLUTION
- 2010
-
In: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526. ; 18:Supplement 1, s. 4-8
-
Journal article (peer-reviewed)abstract
- The objectives and methodology of the EU-funded research project HYVOLUTION devoted to hydrogen production from biomass are reviewed. The main scientific objective of this project is the development of a novel two-stage bioprocess employing thermophilic and phototrophic bacteria, for the cost-effective production of pure hydrogen from multiple biomass feedstocks in small-scale, cost-effective industries. Results are summarised of the work on pretreatment technologies for optimal biodegradation of energy crops and bio-residues, conditions for maximum efficiency in conversion of fermentable biomass to hydrogen and CO2, concepts of dedicated installations for optimal gas cleaning and gas quality protocols, as well as innovative system integration aimed at minimizing energy demand and maximizing product output. The main technological objective is the construction of prototype modules of the plant which, when assembled, form the basis of a blueprint for the whole chain for converting biomass to pure hydrogen. A brief outline is presented of the progress made towards developing reactors for thermophilic hydrogen production, reactors for photoheterotrophic hydrogen production and equipment for optimal gas cleaning procedures.

European energy regulators' views on regulation smart distribution networks
- 2011
-
In: Proceedings of CIRED 21st International Conference on Electricity Distribution.
-
Conference paper (peer-reviewed)abstract
- The European Energy Regulators’ Group for Electricity and Gas (ERGEG) launched a public consultation on its position on smart grids on the 17th of December 2009. The consultation period ended on the 1st of March 2010 and ERGEG published a Conclusions Paper, including an evaluation of comments received, on 10 June 2010. This CIRED paper addresses the regulatory priorities highlighted by the consultation that the development of smarter electricity networks will present. Its focus is on distribution networks. It explains the drivers behind the consultation, reviews the key issues addressed and summarises the conclusions reached.
