Dr Bob Scholes presentations


Dr Bob Scholes is one of the members of the South African Environment Observation Network (SAEON) technical panel. He also leads the ecosystem processes and dynamic research group at the CSIR which is about global climate change, biogeochemistry, ecosystem dynamics of savannas and earth observation systems. Dr Scholes is a very intelligent man, he also gifted and he was a very good presenter. His presentations were about “the value and philosophy of the long-term earth observation science”.

The changing face of the research

Dr Scholes explained about the changing face of the science. He explained about three types of pillar land scape, which are research, observation and assessment. He said that the scientists need to do a research, observation which also goes together with assessments well as social needs. All these pillars are very much important for the scientist.

Social need

Dr Scholes also said that it impossible to observe everything, everywhere all the time. So you do not want have to observe everything, everywhere all the time. He also said that you have to sample the information cube sparsely and you have to organise yourself hierachically. .We was told that we have to measure many things at a small place and we can measure a few things at a lot of site. He said that you have to use models to interpolate the entire information volume meaning that every observation is a model.


Dr Scholes also presented about an Interoperability which is the long word for standards. He said that a lot of Interoperability is a computer communication protocol, and data base structure convention for example XML (ABCD) Darwin core etc.


Dr Scholes presented about a metadata and he said that many people need to know but they are afraid to ask He said that part of your scientific have a responsibility. If we need to know something we do not have to ask so that we can know better and learn more.

Sharing data

This was his last presentations and he explained about the collected data on the public. Dr Scholes said that the unused data is valueless and if got the money, it does not belong to you. He also said that the default case is a public domain and there is a restricted access needed. He said that you are given a limited period such as 3 months and this is for NASA and 2-3 years is for the Msc and PhD. A researcher needs to make his/her data available and intelligible. He said that the acknowledge data that you use must have the reference and co-authorship.


The presentation was good. The aims was to encourage students to align their research with SAEON‘s programmes. It was also to stimulate and promote interactions among graduate students and senior scientists, within the realm of long-term environmental research. Another aim was to provide a network in which graduate students can feel comfortable to share ideas, to collaborate with one another and to get a broader understanding of ecological research with an expanded context in which to view their own research. The last aim was to inform graduate students of career opportunities as they become available.
