  • 1. Task Force on Land and Soil Objectives / on-going activities / potential developments Richard Escadafal (1), Maria Jose Marques (2) , Mariam Akhtar-Schuster(3)the United Convention to Combat desertification (UNCCD), has been diagnosed as still suffering from a lack of scientific guidance. Whereas, climate change and biodiversity issues –the other two big subjects of the Rio Conventions- seem to progress and may benefit France advice of international science-policy (1) Cesbio, Toulouse, from the panels/platforms. (2) Universidad Autónoma, Madrid, Spain,In an attempt Secretariat DesertNet International, Hamburg, Germany (3) to clarify the debate around the type of platform / panel / partnership needed, we have launched a “Task Force” to analyse the components of the scientific communities dealing with LAND and/or with SOILs.

  • 2. this presentation is based on TF outputs : results presented at the EGU meeting, Vienna1 How desertification research is addressed in Spain? Land versus Soil approaches Celia Barbero (1), Maria Jose Marques* (1), Manuel Ruiz (1), Richard Escadafal* (2), Williams Exbrayat (3) Mariam Akthar-Schuster* (4), Anass El Haddadi (5),2 The current structure of key actors involved in research on land and soil degradation. Analysis of the strengths and weaknesses of links Richard Escadafal* (1), Celia Barbero (2), Williams Exbrayat (3), Maria Jose Marques* (2), Mariam Akthar- Schuster* (4), Anass El Haddadi (5), Manuel Ruiz (2) * (members of DesertNet International) Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 3. Understanding the current structure of the scientific community IPBES IPCCThe analysis of scientific Global Soilpublications can give us Partnershipinformation to clarify thecurrent approaches of soilor land degradation issues. ? Soil IssuesDNI is the right place to do it Land Issuesthrough its role ofindependent think tank Desertification Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 4. desertification is a “weak” topic ? “desertification”grows faster than average ! But surprisingly fast growing ! average number of publications per year Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 5. Simple global statistics Citation rates of countries are different when looking at affiliation (address of author) Number of citations of the different or at topic (country subject of the research) countries in ‘topic’ Multidimensional analysis provides insights Number of citations of the different (see next) countries in ‘Authors address’ in both cases China is ranked first and Spain is next!Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 6. Bibliometrics applied to desertification : 1) the Spanish caseBibliometric methods are used to tracequantitative relationshipsamongstacademic journal citations and the impactof any fields, authors or articles.Among the online databases , the mostdetailed in terms of information perpublication is the Web of Knowledge(WoK)Each record includes title, authors and theiraddresses, abstract, keywords, disciplines,cited references, etcperiod studied:1989-2012 Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil

  • 11. Some findings for Spain The core of research addresses Erosion, Soil, Vegetation and Modelling: SOIL SCIENCE (Basic Research) Soil erosion (most important cluster) is not linked with DesertificationVery few articles address Biodiversity, Sustainability, Policy,Development or Economy: LAND ISSUES (Applied Research)In brief, 2 main features:1st. basic science studying the soil in depth, but it is oftendisconnected from socio-economic factors.2nd. applied science being linked to socio-economic issues Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 12. 2) Multicriteria analysis applied to a “global” subsetConsidering the whole WoS database, we have progressively narrowed thefocus through different queries :1st query : Topic=(dry*land* or arid or semi*arid or subhumid)yielded 41 806 references (!)2nd query : Topic=(dry*land* or arid or semi*arid or subhumid)AND Topic=(desertification) yielded 1 144 referencesThe text mining techniques mobilised by the TETRALOGIE (1)software allows multi-dimensional analysis and clustering, it has been used to evidence links not easily visible,among the authors, countries, topics, disciplines.(1) Property of Institut de Recherche en Informatique de Toulouse, France Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 13. links between authors (through co-authorship) Collaborations between authors based on the number of co-authorships Clusters are evidenced names have been as well as abbreviated for data processing and are cited pivot authors establishing just for illustration, bridges between teams (the graph does not portray any ranking) Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil

  • 15. land / soil vs Disciplines The topics ‘soil’ and ‘land’ (red dots ) show common links to disciplines (blue dots) but also some unique ones (highlighted)Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 16. Conclusions of this first explorationThe set of references analysed represents only a limited part of the scientificcommunity involved in desertification, but its analysis led to some interesting findings :  The fast growing number of publications on desertification demonstrates a strong interest  A large part of the recent growth is linked to the involvement of Chinese institutions and journals  in Europe, Spain is the big ‘player’ Text mining techniques combined with multi-dimensional analysis allowed to: • evidence clusters of authors bridged by ‘pivot’ authors • shed light on established cooperations among countries Plenty of room seem to remain for strengthening links and collaborations Land related papers seem more social sciences oriented, whereas soil related ones refer more to ‘hard sciences’ Bonn, April 11, 2013 * DesertNet International meeting * Task Force on Land&Soil
  • 17. Further work within this Task Force In this first analysis, we have been dealing only the tip of the iceberg.. the 1100 articles analysed , published in English in international journals do notrepresent the vast community of ‘desertification research’ A large part valuable information and results is published in the working langages ofaffected countries ! More references sources have to be mobilized , examples :  in Spanish: colleagues from Argentina have volunteered to share their own data base of references (a first test of accessing references of LAC region)  in French: OSS (Tunis) has provided us with its list of references for Africa More need to join the effort if we want to achieve a balanced view DNI could benefit of further work of the TF to better assess its ‘representativeness’ ,to identify gaps between disciplines, to foster networking and to propose a rational basisfor the composition of “group of scientits” providing advice to the UNCCD,Such endeavour requires further research and funding !e.g. Text mining techniques are powerful but require extended data, careful formatting for cross-compatibility between databases,.. = substantial pre-processing !
