A study was undertaken for developing rainfall scenarios using the ensemble of all 16 different Global Climate Model outputs for A1b scenario for mid (2040-2069) and end (2070-2099) century. For the analysis, the entire Cauvery basin was demarcated into five smaller basins viz., Basin 1 (Upper Cauvery upto Mettur reservoir), Basin 2 (Bhavani basin from Mettur to Upper Anicut), Basin 3 (Amaravathy basin), Basin 4 (Upper Anicut to Grand Anicut) and Basin 5 (Downstream of Grand Anicut, including lower Anicut and the delta region). From the 16 Global Climate Model ensemble outputs, rainfall in the mid century is expected to increase in the SWM months starting from May through December in the order of 1 to 36% (Basin 1), 3 to 21% (Basin 2), 1 to 17% (Basin 3), 3 to 22% (Basin 4) and 4 to 22% (Basin 5). The same trend is expected in the end century with different magnitude. The South West Monsoon (JJAS) and post-monsoon rainfall (ONDJ) is expected to increase towards mid and end century whereas not much change is expected in the pre-monsoon rainfall in the future. Annual rainfall is expected to be 21, 11 and 7% more during mid century compared to the baseline (1981-2000) in the upper Cauvery (Basin 1), mid Cauvery (Basin 2, 3 and 4) and delta region (Basin 5) respectively. The rainfall would be higher by 33, 15 and 10% than the current quantity in the upper Cauvery, mid Cauvery and delta region respectively during end century. These results could contribute to the development of policies for future agricultural water management.Keywords

RegCM is a Regional Climate Model (RCM), mostly applied in regional climate change and seasonal prediction around the world. The International Centre for Theoretical Physics improves this model and releases updated version over years. In the present study a comparison was made between RegCM3 and RegCM4 versions of this model in simulating climate change over Cauvery Delta Zone of Tamilnadu. The simulations were made using ECHAM5 global climate model outputs of A1B scenario with a resolution of 25 km from 1971 to 2100. The comparison of yearly and decadal means indicated that there exists a significant and positive difference in simulation of rainfall and relative humidity by RegCM4 while solar radiation, maximum temperature, minimum temperature and wind speed showed significant negative difference. The Seasonal and monthly comparisons revealed that difference across weather variables is not consistent as that of yearly and decadal. The decadal projections showed a marked increase in maximum temperature, minimum temperature and rainfall. A slight increase in relative humidity and a slight decline in solar radiation and wind speed were noticed under RegCM4 simulations.Keywords

A methodological study was made at the Agro Climate Research Centre, Tamil Nadu Agricultural University, and Coimbatore during 2012 to identify the potential districts for cultivation of rice, maize and groundnut in Tamil Nadu. The data on area, production and productivity of study crops for 2000–‘01 to 2009–‘10 were collected and indices such as Relative Spread Index (RSI) and Relative Yield Index (RYI) were computed and the potential cropping districts for the study crops were identified. In Tamil Nadu, nine districts were found to be prospective regions for rice, seven districts for maize and three districts for groundnut as in these areas both the RYI and the RSI were high. In some of the districts, RSI is more for a particular crop, while the RYI is low indicating non suitability of that crop. However, due to other factors such as market demand and value of the produce, farmers cultivate the crops that are not suitable for their location which relates in high RSI with low RYI.Keywords

Insects, as cold-blooded animals are directly under the control of temperature for their growth and they cannot sustain living below and above certain thresholds. Therefore, temperature is probably the single most important environmental factor influencing insect behavior. Current estimates of changes in climate indicate an increase in global mean annual temperatures of 1°C by 2025 and 3°C by the end of the next century. Such increases in temperature may decrease the developmental time and increase the number of generations per year. An investigation was adopted to understand the effect of five different constant temperatures (28.3°C, 30.6°C, 32.7°C, 34.3°C and 36°C) on the development time of Yellow Stem Borer (YSB). The results revealed that the number of eggs laid by YSB increased at higher temperatures while egg hatching was reduced. Egg hatching was higher (90.6%) in 30.6°C followed by 28.3°C. The development time taken by different stages of the YSB revealed that there was an inverse relationship with development time and incubation temperature level. Insects develop faster which may oviposit early and hence the population was likely to grow earlier than expected.Keywords

A study was carried out at Agro Climate Research Centre, Tamil Nadu Agricultural University using PRECIS and RegCM4 Regional Climate Models (RCMs) by downscaling HadCM3 (Q0) and ECHAM5 global climate model outputs at 25 km resolution. The downscaled data obtained from the RCMs were verified with CRU observed climatology and found to have good agreement. Four weather variables viz., maximum temperature, minimum temperature, solar radiation and rainfall were extracted and employed in DSSAT crop simulation model for rice yield simulation for agricultural grids of Tamilnadu State India from 1971-2100. Two treatments were fixed as control and CO2 enriched conditions. The maximum temperature and minimum temperature showed increase in temperature at the end of the century with high rate of increase for minimum temperature. Rainfall exhibited high variability. The rice yield simulations showed decline in yield in the study period for both control and CO2 enriched conditions, with later consistently showing higher yields than the former till the end of 21st century.Keywords

Background/Objectives: WBCIS products proposed by three insurance providers were evaluated using historical weather data for kharif rice in Dharmapuri, Theni, Tirunelveli and Virudhunagar districts of Tamil Nadu. Rice is sensitive to moisture stress at reproductive stage as it consumes large amount of water during the major part of reproductive phase. Results/ Findings: Evaluation of the strike events revealed that all the study districts are highly vulnerable to deficit rainfall risk. The soil factor and the intensity of rainfall during critical stages of the crops must be considered for excess rainfall. Water holding capacity of the soil and the daily ET must be taken into account for consecutive dry days. Conclusion/Application: Hypothetical analysis showed that the product designed by AIC for Virudhunagar was reliable both in terms of threshold values and compensation rate per mm of rainfall under different phases of crop growing period. This could be supported through higher monetary returns benefited by the farmer at Virudhunagar district.Keywords

Weather-based crop insurance scheme (WBCIS) products proposed by four insurance providers was compared and evaluated using historical weather data for piloting WBCIS on kharif groundnut in Coimbatore, Dharmapuri, Theni, Tirunelveli and Virudhunagar districts of Tamil Nadu. Water deficits during the vegetative phases of groundnut crop generally delay flowering and maturity thereby reducing the crop growth and yield. The study revealed that the deficit rainfall risk was more pronounced in all the abovementioned districts, whereas the risk of excess rainfall impact could be clearly observed in Theni district. Though the occurrence of strike events was for phase- I of deficit rainfall cover, the rate per mm of rainfall fixed by IFFCO-TOKYO was quite low. The product designed for HDFC-ERGO and MS-Cholamandalam was similar, whereas the product for AIC and IFFCO-TOKYO was designed with little variation in context to excess rainfall cover and consecutive dry days. The compensation benefit realized by the farmers of Virudhunagar and Dharmapuri districts was higher followed by Theni because the compensation rate per mm of rainfall fixed by the company was higher, which favours the farmers.Keywords

A study was undertaken to understand the effect of increasing temperature on population dynamics of yellow stem borer (YSB), Scirpophaga incertulas. Experiments were carried out in a temperature control chamber with five different constant temperatures (28°C, 30°C, 32°C, 34°C and 36°C). The data on agespecific life table at varying temperature regimes revealed that the total lifespan of YSB extended to a maximum of 52 days at 28°C followed by 49 days at 30°C and 46 days at 32°C. In general, survival of the YSB decreased with increasing temperature. Preoviposition period for YSB also decreased with increasing temperature. However, the total number of eggs laid by YSB increased with increasing temperature. Also, 50% fecundity in YSB was recorded on 49.7 days after incubation at 28°C, whereas it was observed as early as 34.4 days at 36°C. All the growth parameters were observed to decrease at 36°C, which reveals that temperature increase above 34°C is detrimental to the development of YSB. The above results reveal that, if the global warming continues at the present phase, it will negatively influence YSB and the population growth will be severely affected in the near future.Keywords

Impacts of elevated temperature and carbon dioxide (CO2) enrichment on rice were assessed by carrying out an experiment with four dates of planting (1 June and 15 June, 1 and 15 July) during 2014 under two different environmental conditions, viz. ambient and modified (climate control chamber) with +4°C compared to the ambient temperature and CO2 enrichment of 650 ppm. Crops grown under modified environment recorded reduced growth characters (leaf area index, dry matter production, number of tillers m-2), lesser dry matter partitioning towards grain, yield attributes (number of productive tillers m-2, number of filled grains panicle-1) and lower grain yields compared to those grown under ambient condition. Crops subjected to elevated temperature and enriched CO2 attained panicle initiation, flowering and maturity earlier than those under open ambient condition.Keywords

Trend analysis of annual rainfall over the coastal districts of Odisha, India showed statistically nonsignificant increasing trend in all districts, except Ganjam. Whereas the maximum and minimum temperature showed significant increasing trend. Warming in these districts is mainly due to increasing minimum temperature during summer and rainy season, and maximum temperature during winter. Future climate projection results revealed, the annual mean rainfall is expected to change by 0.1–2.2%, –0.3–0.7% and 1.5–3.2% (RCP 4.5), and 3.6–7.9%, 3.7–6.6% and 8.5–14% (RCP 8.5) during the near (2011–39), mid (2040–69) and late (2070–99) centuries respectively. Anticipate climate change will have a marginal impact on total rainfall, and a major impact on its distribution. The annual mean minimum temperature is expected to increase by 0.60–0.73°C, 0.71–0.88°C, 1.20–1.42°C (RCP 4.5), and 1.77–2.14°C, 1.56–1.68°C, 3.06–3.73°C (RCP 8.5) during near, mid and late centuries respectively. Similarly, the annual mean maximum temperature is expected to increase by 0.61–0.66°C, 0.68–0.72°C and 1.35–1.55°C (RCP 4.5), and 1.79–1.97°C, 1.73–2.01°C and 3.08–3.44°C (RCP 8.5) during near, mid and late centuries respectively. Season-wise projection revealed that the change in rainfall and temperature is expected to be more in winter and summer under both the RCP scenarios. The projected future climate change will have both positive and negative impacts on agriculture. The negative impacts are expected to be more pronounced during kharif in comparison to rabi.Keywords

Hyperspectral remote sensing captures images in multiple wavelengths and is widely used to detect plant stress in agriculture. A study was conducted on brown planthopper (BPH) infestation in rice at various temperature regimes (15°C, 20°C, 25°C, 30°C and 35°C). The experimentation was done in the Environmental Control Chamber, Tamil Nadu Agricultural University, Coimbatore, India. The field spectroradiometer and vegetation indices were used to study the early and late infestations of BPH in rice. The results reveal that reflectance at certain wavelengths (550, 670 and 700 nm) indicates plant stress. Among the vegetation indices, MCARI performed better than NDVI, PRI, NDRE and SR for the detection of early and late infestation of BPH. Hence, hyperspectral reflectance from rice has been used to detect pest damage and improve management policies.Keywords
