Belgian Data Gaps

A small study of Biodiversity data published by Belgium.

Transcript

1. BELGIAN DATA GAPS GBIF Webinar, 23 March 2017 , André Heughebaert Belgian Biodiversity Platform
2. “the purpose of the ‘Data Gap Analysis’ is to identify discrepancies between current and ideal states (Research Data Strategy Working Group 2008) of the entire enterprise of biodiversity data management leading up to its publishing and usage (Chavan et al. 2010).” Best Practice Guide for Data Gap Analysis for Biodiversity Stakeholders Arturo H. Ariño, Vishwas Chavan and Javier Otegui
3. AIMS Assess Data published by the Belgian BIF Find our strengths and weaknesses Determine where our Data Gaps lie ASSUMPTION Data published from Belgium should not differ from neighboring countries
4. SOURCES 2016 Country reports (Jan 2017) GBIF.org portal (GBIF webservices) (Occurrences downloads)
5. METHODOLOGY Use relative, NOT absolute numbers Compare Belgian percentages to France, Germany and the Netherlands (all VPs since 2001) Strength = significantly above Weakness = significantly below
6. TOPICS 1. Type of data 2. Data completeness 3. Taxonomy, geography, time distribution 4. Georeferencing 5. Licensing 6. Indexing issues 7. Data repatriation 8. Multimedia
7. RESULTS (1) BasisOfRecord Human Obs. 72.28% 70.22% 69.19% 68.90% Machine Obs. 20.54% 0.00% 0.00% 0.00% Specimen 5.05% 9.97% 17.90% 29.05% Fossil 0.00% 2.67% 0.70% 1.68%

9. RESULTS (3) Year < 1900 0.25% 0.73% 1.38% 1.07% 1900..1924 0.45% 0.70% 0.56% 3.06% 1925..1949 4.78% 7.56% 0.44% 5.75% 1950..1974 11.47% 4.13% 0.90% 10.59% 1975..1999 22.50% 22.74% 3.25% 41.98% 2000..2017 58.59% 25.64% 11.18% 22.56%
10. BELGIAN GAPS FOUND Whenever possible, we should try mobilize: 1. Specimens, Fossils and Litterature Occurrences 2. under-represented taxonomic groups 3. Wallonia and abroad (Data Repatriation) 4. Historical data collected before 1925 5. with associated multimedia
11. TAKE HOME MESSAGE Easy exercice ( < 2 man days) O en confirm our feeling, still some surprising results! Baseline for mobilization strategy Opportunity to expand our network
