CROP -TOTAL CLIMATE RISK COMPONENT From end to end- Land preparation, crop sowing –TO Harvest and post harvest operations Consider both –Direct impact- by moisture stress, water logging and on Crop physiology –Indirect impact – by triggering rapid increase of pests, diseases and vector populations that are already endemic. In any particular year a partiuclar combination of such ‘adverse events’ would occur It is possible to construct simple models for such climate impact by using –Existing literature –Expert knowledge of farmers, field researchers
9
NOTE All further slides refer to Rainfed groundnut at Anantpur These are illustrative of methodology similar questions (to the ones mentioned here) were asked by farmers in the study village.
10
Simple model for Rainfed Groundnut At Anantpur- an example
11
Climate – Direct impact
12
Climate- indirect impact
13
TOTAL CLIMATE RISK FOR GROUNDNUT CROP
14
Validation of Model Prediction and Field data
15
Crop model Validation with observed yield
16
Cost of Cultivation Anantpur District average groundnut yield- (1975- 1995) - Avg rain-47 cm
17
Optimal sowing window Frequently asked question No additional cost, but very high benefit for correct choice but, high penalty for wrong choice Need long term daily rainfall, crop simulation model, soil data, crop management data Simple model on pest and diseases would be desirable (Indirect impact of climate )
18
Recent shift in cropping patterns- Lack of experience of optimal sowing windows
19
PUNTGRO- Year wise yield at different sowing dates
21
Low chance of crop failure? – sow late
22
Best chances of High yields? – sow late
23
High chance of Moisture stress at Pod filling (60-85 days after sowing)
24
Low chance of Moisture stress at Pod filling (60-85 days after sowing)
25
Chance of leaf miner incidence v/s sowing date
26
Chance of Late leaf spot v/s sowing date
27
Community level Livelihood options at 3 villages of Anantpur
29
6 villages in Anantpur region Located in 3 separate Mandals, distributed in an area of about 4000 sq km Data from Marginal and small farmers, Vulnerable sections to climate risk Sample of 20-40% of the total families in the community Family wise data collection from 2005 to 2008
30
Family wise Annual income distribution- 6 villages
31
Family wise Cattle population in 6 villages.
32
Family wise sheep and Goat income- 6 villages
33
How much credit?
34
Reasons for first debt ? – crop (during bad year), bore wells, sheep are the big reasons
35
Govt. programs as a safety net
36
CPRs as the safety net
37
Highest number of animals not with the largest of farms
38
Mid size farms have the largest credit
39
Debt trap (3 rd Default) - Reasons
