Outline

● Progress report on global futures activities – maize and wheat

● Future work

Progress on ‘technical potentials’ report

● What to get out of technical potential report: List of promising technologies relative to climate

change adaptation (technologies that can be maintain yields under biotic and abiotic stresses increased by climate change)

Data/information on the growth process of such crops: this data would be fed into DSSAT or other crop models (APSIM)

Progress on ‘technical potential’ report

● Maize: draft report has been submitted (dropbox) List of promising technologies (existing technologies) were

identified: varieties with tolerance to drought and water-logging; some DT varieties that are also resistant to heat stress

Identification of on-going breeding efforts to develop improved maize varieties

Conservation agriculture: trial data exist Trial data exist for these technologies; they now have to be

evaluated to see whether they can be fed in DSSAT (compare trial data and data requirements in DSSAT)

Progress on ‘technical potential’ report

● Wheat: draft report has been developed Report does not have specific names for promising technologies

(climate change) Report needs to be updated to include:

List of varieties (current and improved) that can be promising technologies (climate change):

– Diseases» Rusts (SR, LR, YR), septoria leaf blotch and septoria nodorum;

root pots; BYDV; bunts (including kernel bunt): resistant varieties already exist

» Tan spot; leaf blight: work is on-going– Pests

» Sun pest, green bug (aphid): work is on-going» Russian wheat aphid, hessian fly: resistant varieties already exist

Trial data exist; it also has to be evaluated to see whether it can be fed into DSSAT

Way forward: short-term

● Maize: Compare available regional trial data with data

requirements in DSSAT Ongoing work with CIAT in CA (Tortillas on the roaster)

● Wheat Finalize draft report on promising wheat technologies

given climate change Compare trial data with data requirements in DSSAT

Way forward: short-term● IMPACT training at IFPRI (April/May, 2011)● DSSAT Training Muscle Shoals (May, 2011)● Visit to Mexico (May 2011)

Meet with wheat scientists Work with Kai on DSSAT and establishing ‘links’ with

IMPACT Identify cultivars for DSSAT modeling: Discuss the mega and/or point level DSSAT modeling

choices for maize and wheat in different regions (depends on data and cultivars)

Discuss crop data collection for DSST runs with breeders

Way forward: short-term

● Assessment of socio-economic and biophysical data on crops (wheat atlas, CRP data bases, sub national data compilation)

● Comprehensive list of scenarios on key environmental and socioeconomic drivers of global change

● Assessment of alternative agricultural research technologies applicable to regions to accelerate attainment of MDG goals

● Assessment of Mega Environment Changes● SPAM verification (Maize done, Wheat to follow)● Run DSSAT on Nairobi cluster (CA Maize, India Maize)

Way forward: medium- to long-term (outline for report on IMPACT modeling)

● IMPACT model calibration (maize and wheat)● Identification of cultivars suitable for different mega-

environments and evaluate● Future crop varieties (virtual crops)● Estimate yield potential under future climates (2020, 2030,

2050, 2080?)● Impact of climate change using existing varieties and best-

bet agronomy● Impact of climate change using future technology options

(i.e. with adaptation options)● Compare with baseline conditions (impact of climate

change with and without adaptation options)
