Group 5: Climate Change Network. Networking of various institutions on climate change

Transcription

1 Review and Planning Workshop: Bhoochetana II and GoK-CGIAR Initiative Date: 01 Mar 2013 Topic of discussion: Technical Session VI: Group Work Leader: Dr. Prabhakara Setty, DoA, GoK Assistance: Dr. AVR Kesava Rao, ICRISAT Time: 15:30 to 17:30 h Assess the impacts of climate change in different agro-eco regions of the state in terms of anticipated shifts in the crop growing periods, water availability, major crop yields, and evaluate adaptation strategies for developing climate resilient farming systems Networking of various institutions on climate change

2 How did we go about it Group consisted of more than 50 participants including a good number of women Participation from all organizations: DoA-GoK, SAUs and ICRISAT Dr. Prabhakara Setty introduced the topic, explained about global warming, present climate change scenario, drivers and impacts on agriculture and society, advantages & disadvantages Dr. Kesava Rao explained the methods of collection of weather and soil data and development of databases, climate variability and change analysis at micro-level, climate change impacts assessment, development of suitable adaptation strategies and enhancing climate awareness among various stakeholders Active participation by majority of members has resulted in many good suggestions and a clear road map

3 Climate change: Mega concerns Increase in temp by 1 o c increases the sea level by 1 foot due to dissolution of polar ice caps, GHGs(CO 2, CFC, CH 4, H 2 S) Increase in temperature increases the productivity of C4 plants: maize, sugarcane In Karnataka, past 10 years rainfall trend signifies 6/10 years being drought affected Neighboring districts have opposite trends!

4 Group 5: Climate Change Network Weather aberrations

5 Some impacts of weather aberrations Higher humidity: Causes sheath blight in paddy Flower dropping in Pigeonpea Reddening of cotton Higher temperature: Increased bee activity High evapotranspiration demands Lower temperature: Better tuberisation in potato Increased sugar content in sugarcane Increased oil content in oilseeds Strong winds: High evapotranspiration demands Lodging of many crops

6 Suggestions by group Appropriate crop varieties to suit the change in climate zone wise need to be developed by universities Intermediary and contingent crop planning / alternate crop planning system to be developed In-situ moisture conservation, Mulching / application of FYM to increase soil organic matter content Hydrogel technique Conservation tillage Repeated inter-cultivations Dead furrow opening Sowing across the slope Water harvesting & application of micro irrigation system

7 Suggestions by group Seed hardening with CaCl 2 Intercropping in horticultural and plantation crops Introduction of Silvi-Agriculture, Agri-Horticulture, Pastoral systems based on land capability classification Rehabilitation of wastelands through biofuel plantations Maintaining optimum plant population with suitable crop geometry Adoption of drought tolerant varieties Foliar nutrition, Growth promoting hormones, Anti-transpirants Protective / Life saving irrigation at critical stages Reducing agricultural GHG emissions Post-harvest management Emphasis on carbon sequestration and initiate carbon trading

8 Road map Climate and soil data collection Sources: IMD, KSNDMC, SAUs, Directorate of Economics & Statistics Quality check, database development, software for analysis Climate change analysis with respect to Trends in major weather parameters Changes in begin and end of rainfed crop-growing period Changes in LGP, intra-seasonal dry and wet spells Water balance and water availability for crops Identification of areas with great changes in climate (hot spots)

9 Road map Assessment of climate change impacts on major crops through crop-growth simulation models Development of suitable climate resilient adaptation strategies Organizing climate awareness programmes on wider scale

10 Road map Sites: Representative 10 ha area in each of the four districts (Bijapur, Raichur, Chikkamagalur and Tumkur Establish AWS to be done by ICRISAT in collaboration with Dept of Agriculture, KSNDMC and SAUs Monitor weather, crop parameters in details Monitoring occurrence / outbreak of pests and diseases Develop weather-based pest / disease forewarning models Strengthen the weather forecasting system for the target sites and extend it to the entire division in due course Awareness building programmes on climate and its impact

11 Collaborations from other institutions SAUs (Each university to nominate one scientist exclusively to assist the team) Tumkur UAS, Bangalore Chikkamagalur UAHS, Shimoga Raichur UAS, Raichur Bijapur UAS, Dharwad KSNDMC ICRISAT Road map Departments of Agriculture, Horticulture, Animal Husbandry, Sericulture, Fisheries, Forestry, Agricultural Marketing and Cooperation
