National Academic Research and Collaborations Information System (NARCIS) is the main Dutch national portal for those looking for information about researchers and their work. NARCIS aggregates data from around 30 institutional repositories. Besides researchers, NARCIS is also used by students, journalists and people working in educational and government institutions as well as the business sector.
NARCIS provides access to scientific information, including (open access) publications from the repositories of all the Dutch universities, KNAW, NWO and a number of research institutes, datasets from some data archives as well as descriptions of research projects, researchers and research institutes.
This means that NARCIS cannot be used as an entry point to access complete overviews of publications of researchers (yet). However, there are more institutions that make all their scientific publications accessible via NARCIS. By doing so, it will become possible to create much more complete publication lists of researchers.
In 2004, the development of NARCIS started as a cooperation project of KNAW Research Information, NWO, VSNU and METIS, as part of the development of services within the DARE programme of SURFfoundation. This project resulted in the NARCIS portal, in which the DAREnet service was incorporated in January 2007. NARCIS has been part of DANS since 2011.
DANS - Data Archiving and Networked Services - is the Netherlands Institute for permanent access to digital research resources. DANS encourages researchers to make their digital research data and related outputs Findable, Accessible, Interoperable and Reusable.

Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of crucial importance in global change studies, for example. However, VI time series typically contain a strong seasonal signal which complicates change detection. Commonly, trends are quantified using linear regression methods, while the effect of serial autocorrelation is remediated by temporal aggregation over bins having a fixed width.
Sampling efficiency of national, EU and global stratifications : exploring by using CL2000
Stratification, dividing the statistical population into less heterogeneous subgroups before sampling, can help improve sampling efficiency by improving representativeness and reducing sampling error. This report explores the added sampling efficiency that is achieved by using the European Environmental stratification for estimating the area covered by the 25 Corine Land Cover (CLC) categories occurring in the semi-natural and managed terrestrial habitats of the wider-countryside.
Betrokkenheid van Nederlandse bedrijven bij transnationale grondverwerving en pacht : een eerste verkenning
Vooral sinds de scherpe stijging van de voedselprijzen in 2007/2008 is er een sterk toegenomen belangstelling van landen en bedrijven om grond in andere landen in gebruik te nemen voor de productie van landbouwgewassen, zowel voor voedselgewassen als voor biobrandstoffen. Het gaat om zeer grote oppervlaktes cultuurgrond, met soms vergaande consequenties voor de plaatselijke bevolking. Naast China en de olierijke maar ‘voedselarme’ landen in het Midden Oosten zijn ook Europese bedrijven actief op dat terrein.
Malaysian water sector reform : policy and performance
One of the measures that can help developing countries in meeting Target 10 of the Millennium Development Goals – halving the number of people without access to water and adequate sanitation by 2015 – is through a water sector reform. In this research the Malaysian water sector reform is assessed by answering the following questions: • How can we understand and explain the policy process of the reform? • To what extent have the outputs of the reform contributed to the realization of the reform’s objectives?
Forest rights : the micro-politics of decentralisation and forest tenure reform in tribal India
Forest rights are of utmost importance for the future of forest initiatives, be it for resource use, management, and conservation, or for climate change adaptation and mitigation. The growing trend towards acknowledging the relevance of the sustainable use and conservation of forests is intertwined with the recognition of the forest rights of people who have traditionally depended on the forests for sustenance – especially marginal indigenous and tribal people.
