Expertise and experience
The Council for Scientific and Industrial Research of South Africa is
a not-for-profit research and development organization, established under
an Act of Parliament, and partly funded by the South African government.
It is among the largest, oldest and most-respected research organizations
on the African continent. The annual budget is about SAR1 billion (~120
million euro). The >2000 employees cover a wide range of research
disciplines. The Natural Resources and Environment (NRE) division employs
240 scientists, of whom about 60 are in the 'Ecosystems' programme.
The participants in this proposal are mostly drawn from the Ecosystems
Dynamics Research Group of that programme, although it is possible that
researchers from other groups (Earth Observation, Ecophysiology etc)
may be called upon as well. The Ecosystem Dynamics RG consists of ten
researchers, with core competence in ecological analysis and modelling,
eddy covariance flux measurement and environmental isotopes.
Role in this project
WP1: Monitoring water, CO2 and energy exchanges over several arid
fineleafed and broadleafed savannas in the northeast part of South
Africa, and supplying ancillary data on weather, vegetation, soils,
disturbance, herbivores etc to allow their interpretation.
WP2: Predicytion of canopy dynamics (LAI) of both trees and grass in
southern African savannas, using environmental and remotely-sensed data;
estimating all major components of the site carbon budget for measurement
sites, including measuring and modelling autotrophic respiration of trees
and grass as well as heterotrophic (soil) respiration; modelling fuel
load and fire-related emissions; publications on the above topics.
WP3: Adaptation and calibration of the SiB model for application in
savannas; modelling fire emissions of carbonaceous products at continental
scale from remotely sensed information and data from climate data
assimilation models; interpreation of land cover and vegetation maps
of Africa for purposes of driving models; publications on these topics.
WP4: Maintenance of a fuel load database for model validation; development
and running of fuel load models; knowledge of emission factors and their
drivers; spatial and temporal modelling of emissions. Publications on
these topics.
WP5: Training courses in the operation of flux measurement equipment in
an African environment; supervision of African students in conjunction
with the University of the Witwatersrand.
WP6: Strategic and project-level assessment methods for establishing the
sustainability criteria of CDM projects; practical knowledge of CDM
registration processes; understanding of CDM economics.
Principal Investigator and collaborators
Bob Scholes, Dr., Principal Investigator, who has been
with the CSIR since 1992. Before that, he led the South African
Savanna Biome Research Programme. He is a systems ecologist, widely
published on the topics of savanna ecology (particularly the
biogeochemistry of fire) and global change. He was a member of the
Implementation Plan Task Team that designed the Global Earth Observing
System of Systems, co-chair of the Millennium Ecosystem Assessment
working group on Condition and Trend, and a former chair of the Global
terrestrial Observing System.
Sally Archibald, is an ecologist studying for a PhD, with
an established publication track record in savanna ecosystem dynamics.
Her research interests are phenology in savannas, and the ecology of fires.
Walter Khubeka, is a technician who operates the Skukuza
flux tower. He has two years of experience in this post, and is responsible
for instrument maintenance, calibration and data capture, as well as
biological sampling.
Tony Knowles, is a PhD student with joint training in
ecology and economics, who is working on the estimation of biophysical
risk in the construction of optimal CDM portfolios.
