2- Though environment sustainably is not explicitly addressed in the project, much of the work
contributes to sustainable intensification which will have indirect impact on environment such as
reduced deforestation and extension of agriculture into more marginal lands
8. Major Research Findings
This is a knowledge intensive project aimed to understand better the impact of climate variability
and change on crop production and develop appropriate information to develop better informed
adaptation strategies. Though several assessments of climate change impacts on agriculture are
available, most of these assessments are based on statistical and empirical models that fail to
account for the full range of complex interactions and their effects on agricultural systems. This
project tried to make more realistic assessment of climate change impacts on smallholder farms
which are highly diverse both in terms of biophysical conditions and the way they are managed.
Process based crop simulation models are the most efficient tools in addressing this diversity.
However, these models are data intensive and required data is not available, especially in African
countries. In addition, the models need to be parameterized and validated to the locally relevant
systems. One of the major achievements of this project is to collect data that is required to calibrate
and validate crop models through extensive experimentation across a range of temperature regimes
relevant to Eastern and Southern Africa. Though the data was used to calibrate crop simulation
model APSIM in this project, the same can be used to calibrate any other model like DSSAT (Decision
Support System for Agrotechnology Transfer).
The field trials conducted under this project are unique and helped in collecting sufficient evidence
on how changes in climate impact the growth and performance of different crops. This information
is a valuable input in improving the crop simulation models which are used extensively to assess
impacts of climate variability and change.
Another important achievement is to understand the gender specific impacts of climate change
especially on households headed by women. The two PhD students that this project has supported
made detailed investigations on this aspect. One of the issues emerging is that adaptation to climate
change requires additional investments such as in irrigation systems, changes in crop and variety mix
and in inputs such as improved seeds and fertilizers. Women farmers have little access to both
information and resources required to achieve this and there is a need to address this by carefully
targeting the women and other disadvantaged sections of the society while promoting adaptation
strategies.
Very little effort was made in the region to characterize the long-term trends and changes in climate
by critically analyzing the historical climate data. This is mainly due to lack of simple tools that can be
7
used to analyze large amounts of data. The project has developed simple spreadsheet based tools
such as “Rainfall analyzer” and “Temperature analyzer” which were immediately accepted by many
researchers in the region. Using these tools the project was able to identify important changes in the
current climatic conditions such as changes in the variability of rainfall.
One of the problems in the region is lack of good quality climatic data. Available data has several
missing values and data on some parameters such as solar radiation which are required to run crop
models is not available. This project has developed and tested a methodology to fill the gaps in
available data and estimate the missing data using MERRA data.
Another key finding of this project is that impacts of climate change can be positive or negative
depending on the current climatic conditions, crops and varieties grown and management adopted.
This is against the general perception that the impacts of climate change are all negative. Hence,
while promoting adaptation strategies, the differential impact of climate change needs to be
considered to develop more realistic strategies and in better targeting of the same. The current
belief that adaptation to climate change requires drought-tolerant crops and varieties and water
conservation measures is not applicable to all locations.
The project made significant contribution to capacity building in the region. In addition to two PhD
students, several researchers and students were trained in the use of identified models and other
tools that are required to make comprehensive assessment of climate change and its impacts on
smallholder agriculture. Now a core team of researchers and students with skills to make critical and
comprehensive assessment of climate change impacts is established and they are actively using the
tools in various other projects they are involved with and/or in their master and doctoral research
projects.
A number of publications and presentations were made and are under preparation based on the
data and findings from this project (Refer to Section 15 for a detailed list). This is going to be an
important contribution to the growing literature on climate change and its impact on agriculture.
Data and information from this project is also assisting projects such as AgMIP (Agricultural Model
Intercomparison and Improvement Project) in which ICRISAT and other partners are involved.
9. Assessment of Research Findings
The research findings are expected to have significant impact on how climate change impacts on
agriculture are understood and on how adaptation strategies are designed. While the well-calibrated
models and tools will help researchers in making more realistic assessment of current and future
climate impacts, the limitations identified will help in further developing these tools to accurately
simulate the complex and diverse smallholder systems. The information generated under this
project provides one of the best and more accurate picture of climate change impacts and is
expected to influence the planners and decision makers of climate change adaptation programs in
designing more appropriate and locally relevant programs.
10. Knowledge Sharing and Partnerships for Impact
The project involved various stakeholders from the beginning and made efforts to disseminate the
project findings as widely as possible. It developed a web page for the project and published half-
yearly newsletters with key findings. These are distributed to all relevant stakeholders. The project
held inception and end-of-project meetings and organized a special session during the Soil Science
Society of East Africa meeting held in Nakuru, Kenya. Many project scientists made presentations in
this session and conference proceedings are currently being reviewed for publication by Springer. In
8
addition, the project team made a number of presentations in various national and international
workshops and also in the in-house meetings of the partner institutions. Several other publications
including two PhD theses and papers arising from that work are currently under preparation. To
date, the findings are largely targeted at researchers, academicians and planners of climate change
adaptation programs in the participating countries. Additional efforts are on to develop appropriate
policy briefs and extension material to disseminate the findings to planners and government and
non-governmental extension agencies.
11. Training
The project conducted a formal training program aimed at introducing and providing hands-on work
experience in using identified tools and in applying them to assess impact of climate variability
during the first year of its operation. The main objectives of the training program are:
Introduce simple tools to analyze long-term climate data and characterize variability and
trends in climate
Demonstrate the potential use of stochastic climate models ("weather generators") and
generate long-term climate data for use with crop simulation models
Familiarize with system simulation model APSIM and conduct scenario analyses to
characterize and quantify climate impacts on agriculture
A total of 17 participants from KARI, Kenya Meteorological Department (KMD) and ICRISAT along
with three students working on topics related to climate variability and change attended the training
program. The program was divided into three sections, each dealing with one of the three key
aspects of the project work. The first section dealt with characterizing the variability in climate, the
second with generating location specific climate change scenarios using outputs from selected GCMs
and emission scenarios and the third component dealt with assessing impacts of climate variability
and change on agricultural systems using crop simulation model APSIM. The participants rated the
program as highly useful and the table below summarises their assessment. This was followed by a
refresher course to address the difficulties faced and make them more comfortable in using them.
All student participants used these tools in their research projects and the researchers used them for
the work under this project and other projects such as AgMIP. In addition, training programs were
also conducted to the technicians managing the trials planned under the project.

12. Lessons Learned
The work under this project was planned and executed extremely well. The selection of sites and
experiments conducted are in line with the activities proposed and have contributed significantly to
the achievement of planned output. All milestones were achieved even though delays were
experienced in achieving some milestones. Important lessons learned include:
The structure of the project requires good quality data from on-station trials for two or more
seasons before the results can be used as inputs in the proposed modeling exercises. As a
result, the project workload is heavily skewed to the later part of the project period, leading
to delays in achieving some of the planned milestones within the project period.
The research stations are very poorly equipped to collect the required data. Some of them
do not have ovens, balances and other commonly used equipment which created problems
in collecting good quality data. However, we were able to source some funds from CCAFS
(CGIAR Research Program on Climate Change, Agriculture and Food Security) and other
programs to support the additional costs incurred in field operations.
Though the trials were planned to collect a set of data that is required to assess the impact
of climate change and identify options to manage them, the technicians managing the trials
lacked the necessary skills to effectively implement them. For example, pigeonpea is a crop
10
new to most technicians. We tried to rectify the same by conducting training programs and
practical field demonstrations.
Budgetary constraints, particularly in Zimbabwe where costs have escalated dramatically,
have delayed follow-on focus group discussions planned to be conducted by the PhD
student, and farmer participatory evaluations of crop management and variety trials have
been postponed somewhat. ICRISAT has provided some additional resources from other
sources to support these threatened activities, including unanticipated additional costs for
operating the runoff plot trials at Makoholi.
13. Future Research Needs
The project made a good beginning by collecting good quality data as required to calibrate and
validate crop models and apply them to assess the impact of variable and changing climatic
conditions. However, there are still some gaps that need further research.
- While APSIM performed well in simulating the phenology of most crops at all locations
based on calibration made with data from one location, the simulated grain and biomass
yields related poorly to the observed data . The model seems to be doing fairly well with
high-input systems but there are problems in simulating the low-input systems. Additional
studies are required to improve the model capabilities in simulating smallholder systems in
Africa which are mainly low-input systems.
- The model simulated maize and sorghum phenology very well. However, there are
problems in simulating growth and performance of legume crops especially beans. Further
research is required to improve the model capabilities in simulating legume crops.
- Evidence suggests that many assumptions made in developing adaptation strategies are
not correct. The perception that crop water requirements increase with increasing
temperature may not be true since the reduction in crop growing period is compensating
the increased demand for water. Also the emphasis on promoting drought-tolerant short
duration crops as an adaptation strategy need reconsideration. The model simulations
suggest that further reduction in growing period of short duration varieties has an adverse
impact on crop yields.
- Evidence suggests that the reduction in crop growing period and associated reduction in
biomass production can be compensated by increasing plant population. This needs
further assessment since increased plant population puts additional demands on the
nutrient and other requirements.
- There is large uncertainty in predicting future climatic conditions especially rainfall. This is
partly due to differences between GCMs and partly due to downscaling. The delta method
used in this project cannot account for the changes in variability and frequency of
occurrence of extreme events.
14. Summary
The project is based on the identified need to have adaptation strategies that are location specific
and are based on sound scientific knowledge. Since climate change is long-term in nature and
modeling is the only option to generate reliable information, the project proposed to use “spatial
analogue locations which are locations that have today the climatic characteristics that are expected
in future to collect data required to calibrate, validate and apply crop simulation models. For this,
the project has identified nine different locations in Kenya and Zimbabwe representing temperature
regimes ranging from 17.7 to 25.90C. A set of four experiments were planned and conducted at all
11
the nine locations to quantify the differences in the growth and performance of four different crops
(two cereals and two legumes) and their response to changes in soil moisture, planting dates and
fertilizer application. The project conducted these experiments over three seasons in Kenya and two
seasons in Zimbabwe. Good data was collected on four key parameters that are required to calibrate
the crop models. The data collected include days to flowering, days to maturity and grain and dry
matter yields. Using the data from one location in the country, the model was calibrated and then
validated with data from other locations. The calibrated model simulated the phenology at all
locations extremely well indicating that the model is capable of simulating temperature effects fairly
well. For example, the days to flowering of maize varied from about 60 days at a warmer site to 120
days at a cooler site and the model was able to simulate this variability fairly well. However, the
model overestimated the days to flowering and maturity in case of bean at the cooler site. The
simulated grain and biomass yields are poorly related to the observed. This is attributed to models
inability to capture well all the biophysical interactions including pest and disease effects. The
response of test crops to changes in management varied from one location to other and form one
season to other. In general, early planting and use of fertilizers up to 40 kg N/ha were found to give
higher yields while no significant response to water conservation practice of tied ridging was
observed.
Long-term climate data for all locations was compiled and analyzed for trends and variability in
rainfall and temperature. A general increase in both maximum and minimum temperature was
observed at all locations. In case of rainfall, no definite trend was observed in the amount or in the
anomalies. However, an increasing trend in its variability was observed from the 10-year moving
average of coefficient of variation. For all locations, downscaled climate change scenarios for mid
(2041-2070) and end-century (2071-2100) periods were developed under two Representative
Concentration Pathways (RCP 4.5 and 8.5) using outputs from five coupled atmosphere-ocean
general circulation models (GCMs). The GCMs used are CCSM4, GFDL-ESM2M, HadGEM-ES, MIROC5
and MPI-ESM-MR. In general, locations in Zimbabwe showed higher increase in both maximum and
minimum temperatures when compared with locations in Kenya. For example, projections by GFDL-
ESM2M for locations in Zimbabwe are higher by 30% for maximum temperature and by 80% for
minimum temperature. Similar differences were also observed in case of rainfall. Most GCMs
predicted an increase in rainfall for locations in Kenya and decline in rainfall for locations in
Zimbabwe. For all locations in Kenya, rainfall is expected to increase by about 9% to end-century
period under RCP 4.5 while for locations in Zimbabwe, the rainfall is expected to decline by 21.2%.
Using the downscaled climate change scenarios and calibrated crop model APSIM, impacts of
climate change on the test crops at all locations were assessed. The impacts of climate change varied
from one crop to the other and one variety to the other. The impacts are largely negative in case of
short duration crops and short duration varieties. This is mainly attributed to the reduced crop
growing period which led to a reduction in the total biomass produced and thereby yields. The
analysis provided key insights into the climate sensitivity of the crops, varieties and management
practices which are extremely useful in formulating adaptation strategies. Results of simulation
analysis indicate that it is possible to reduce the negative impacts of climate change by making
simple adjustments to plant density, fertilizer use and variety.
The project also undertook studies to assess the differential impact of climate change on gender.
Results indicate that the proportions of de-facto female heads at the dry and warmer sites is high
compared to the cool wet sites, mainly due to migration of men to work as labor. Gender differences
exist in preferred crops and management strategies across sites. Women farmers tend to put more
area under short-duration legumes which according to results from simulation analysis are going to
12
be impacted negatively with climate change. In addition, labor for production, pest management,
harvesting and processing, against a background of male labor migration is another major problem
faced by women farmers. This constrains timely operations which are extremely important in rainfed
semi-arid areas. Most women farmers are interested in adopting drip irrigation but are constrained
by lack of investment capacity and access to credit.
The project developed a training program aimed at better understanding the variability in current
climatic conditions, generating location specific climate change scenarios from GCM outputs and
assessing impacts of variable and changing climate on crop production. The participants are now
actively contributing to the climate change impact assessment and adaption work in their respective
countries. The project fully supported two PhD students who have successfully completed their
degrees.
