Linking Model Use with Spatial Information for Improved Extrapolation
of Soil Management Information: visiting scientist opportunities
The project Optimizing Fertilizer
Recommendations in Africa (OFRA) is developing the capacity for much enhanced
farmer profitability resulting from fertilizer use. Decisions are made in
consideration of financial, environmental, and cropping system aspects of the
individual farmer’s context. OFRA is implemented for major food production
agro-ecological zones of 13 sub-Saharan Africa nations. OFRA is funded by the
Alliance for the Green Revolution in Africa, managed by CABI, and technically
supported by the University of Nebraska-Lincoln. Fertilizer optimization tools
(FOT) are developed and deployed for profit maximization of fertilizer use. The
tools employ crop-nutrient functions of diverse crops. The functions are
determined from field research results including from a meta-analysis of
results from past research, current OFRA supported research, and extrapolation
of information across Africa.
The potential for extrapolation
of information across Africa is greater than ever with much improved soil
property, climate, and crop spatial information available that can be linked
with the OFRA compiled database. Linking
crop growth simulation models having nutrient response sub-routines such as
DSSAT and APSIM, or crop response calculators such as QUEFTS, with spatial
information is a potential means to improved extrapolation of nutrient response
information.
The visiting scientists are
expected to produce a paper for journal publication demonstrating the use of a
model in extrapolation of crop nutrient response information and to develop
guidelines to enable professional GIS practitioners of NARS and universities to
conduct such applications. The guidelines or tools developed will be compatible
with ArcGIS and, if feasible, with a freeware, menu-driven option such as
Q-GIS.
OFRA will support two sabbatical
positions of two month duration to be implemented simultaneously in 2015. These
positions will be accommodated at ILRI (together with office space) in Ethiopia
to enable adequate consultation with other specialists. The work will be
supervised by Prof. Charles Wortmann of the University of Nebraska-Lincoln as
well as by Dr. Kindie Tesfaye Fantaye of CIMMYT and Dr. KPC Rao of ICRISAT both
located at ILRI in Addis Ababa.
Candidates need to provide strong
evidence of expertise and practical application of GIS (analysis and advanced
querying), geo-statistics, model use, and interface tool development. The
candidates need to have well-established and on-going employment with an
African research organization or university.
The compensation package includes a monthly stipend of US$
1,000 and full board arrangement where accommodation and meals will be catered
for at the ILRI campus. Candidates will be expected to bring a laptop well
equipped with appropriate software. Up to $500 will be available for software
licenses. The positions are to begin 3rd August 2015.
