Climate variability at Nemmikal, Nalgonda
After 1978, climate tending towards Arid type, LGP reduced by 15 days
Old varieties of Maize, Pigeonpea are likely to fail more number of times
Potential for crop diversification and introduction of climate smart varieties
Changes in duration of southwest monsoon in Myanmar
Onset in northern Myanmar till withdrawal from southern Myanmar(1955-2008)
Projected climate change related disaster risks in Myanmar
Opportunity for drought and heat tolerant climate smart varieties
• Help in climate change impacts assessment
• Cultivar coefficients for groundnut, pigeonpea estimated

Increase in temperature by 2oC reduces crop yields by 16% and TDM by 9%
Increase in temperature by 2oC, reduces crop duration by 9 days without changing plant water use
Increase in temp by 2oC coupled with decrease in rainfall by 20% may result in yield reduction by 28%

Dual-purpose Raingauge
• Designed by ICRISAT
• Perhaps only such instrument in the world
• Allows both manual measurement and automatic event recording of rainfall
• Also records air temperature
• Total cost including equipment, testing, calibration, launching, installation and one-year technical support is about Rs.53,000/-
Training to students to operate and maintain the Automatic Weather Station
Students collect weather data daily and display at the school
Weather awareness at watersheds
Suggesting optimum groundnut sowing period
• Pilot study in collaboration with Microsoft team
• Devanakonda Mandal in Kurnool district
Prediction of Spodoptera adult population
El Niño is present and is weakeningA transition to ENSO-neutral is likely during late Northern Hemisphere spring or early summer 2016, with an increasing chance of La Niña during the second half of the year

Likely rainfall situation in Telangana during Jun to Dec 2016
(Under prevailing strong El Niño conditions till April 2016)
• Update climate databases at micro-level
• Climate change analysis and assess climate change impactsusing cop-growth simulation models
• Monitor weather at project sites through automation andparticipatory methods (farmers and NGOs)
• Enhance awareness on climate variability and change
• Develop Climate Decision Support System includingweather-based pest forewarning models
Proposed work plan
We have no time to lose
• Global warming tolerance thresholds, not too far • Adaptation + mitigation approach crucial• Time to join hands to harness strengths of all partners
Time to take off
Thank You
