O paper On Digital Soil Mapping (GEODERMA, 117 (1-2): 3-52 NOV 2003),
elaborado pelo pesquisador Alex McBratney (Universidade de Sydney,
Austrália) em parceria com a chefe geral da Embrapa Solos Lourdes
Mendonça e o também pesquisador Budiman Minasny (Universidade de
Sydney) é citado pela Science Watch como artigo emergente de pesquisa
no campo da ciência agrícola em dezembro de 2009. Além disso, tem sido
citado com grande frequência.
Leiam abaixo entrevista com Alex McBratney sobre o trabalho:
Why do you think your paper is highly cited?I think it both defined a
new approach and brought recognition to a
new area of research and application. It is also timely because, at
the turn of the century, scientists recognized the difficulty of
conventional soil mapping. With limited budgets, soil and
environmental scientists are looking for new ways of producing soil
and related maps more efficiently.
Does it describe a new discovery, methodology, or synthesis of
At first this paper was a review, then, after some thought, it became
a synthesis, and then, after some further thought, it was clear that
there was a more generic approach that could be developed. This is a
good example of going from review to new ideas. The paper probably led
to a scientific movement which then led to a global project.
This paper introduced the quantitative scorpan concept, where soil can
be predicted from S: soil, C: climate, O: organism, R: relief, P:
parent materials, A: age, and N: geographic space. It also proposed
the spatial soil prediction function which allows us to spatially
predict soil properties across any region of interest.
Would you summarize the significance of your paper in layman’s terms?
It suggests a new way of doing soil mapping that uses the latest
technology and our best ideas about how soil varies across a
landscape. The new way is potentially much more efficient and more
quantitative than the old one.
How did you become involved in this research and were any particular
problems encountered along the way?
I’ve been involved in various aspects of quantitative soil mapping my
entire research career. It was only with the time for reflection that
sabbatical leave allows that I could thoroughly investigate what
everyone had been doing during the previous years, and see the threads
and commonalities to put it all together, and then suggest a new way
It only goes to show that time set aside for reading and reflection is
quite important for the development of science and, too often, this
opportunity is denied us by the increasing hurly-burly involved in the
administration of science.
Where do you see your research leading in the future?
This research has led to a movement of people across the world who are
investigating digital soil mapping as a way of producing soil
information for today’s problems. Several conferences have been held
and books have been produced and there is a growing literature in the
scientific periodicals. Most importantly, there is now a global
project to produce a global map of soil properties at a resolution of
90m x 90m.
This idea was not even conceived at the turn of the millennium.
However, after the first and second conferences on digital soil
mapping, which were held in 2004 and 2006, subsequent to the
publication of our Geoderma paper, a group of people felt confident
enough that we could achieve such an aim. It’s a great challenge but
it’s one that we must engage. Some of the aspects of this were
described recently in a paper by Pedro A. Sanchez, et al. “Digital
soil map of the world,” Science 7(325): 680-1, August 2009.
Do you foresee any social or political implications for your research?
The paper probably led to a scientific movement which then led to a
global project. The major aims of the global project are to produce
relevant soil information for solving today’s and tomorrow’s great
problems: food security, water security, energy security, and
sustainable response to climate change. The information digitally
produced by global soil mapping will allow modelers, planners, and
policymakers to put in place responsive and responsible actions for
the use of the global community.
