TNAU to study impact of climate change on crops, find solutions


Coimbatore: The Directorate of Crop Management on the Tamil Nadu Agricultural University (TNAU) has undertaken a challenge to research how climate trade would have an effect on agriculture within the state and to increase adaptation options.
The inter-disciplinary challenge is titled - Building Resilience to Climate Change and Improving Food Security through Climate Smart Solutions (BRIFS). It seeks to research quite a lot of aspects associated with climate trade and agriculture from soil stipulations to gene make-up of vegetation to financial elements of climate trade and its affect. The challenge supported by means of the department of science and era (DST), under the ministry of science and era. The monetary outlay for the challenge is Rs2.42 crore, a TNAU official said.

Speaking of the challenge’s scope, director of crop control at TNAU and the predominant investigator and coordinator of the challenge V Geethalakshmi said by means of the mid-21st century, the temperature within the state would go up by means of 1.4°C to 1.5°C. Also, the rainfall would increase by means of 5% to 10%, however the choice of rainy days would decrease. This would lead to extremities in climactic stipulations, she said, adding that the challenge seeks to search out adaptation methods under such stipulations.

The university is within the procedure of creating facilities for the analysis by means of acquiring apparatus and setting them up. “We would set up facilities equivalent to climate keep watch over chambers which would take care of particular levels of temperature, humidity, mild and CO2 levels. We will set up the climactic stipulations anticipated in 2040s and 2050s within the chamber and develop plants in it to study the affect,” Geethalakshmi said.


The university is within the procedure of buying micro-climactic instruments equivalent to units to measure photosynthesis and leaf area, at a value of Rs50lakh, and would quickly set them up on the campus. “For the following two years we would behavior continuous and intensified analysis on this line,” Geethalakshmi said.


Some of the necessary parameters the researchers would probe into had been the effect of temperature on the microbial and natural content material in soil and the genes liable for temperature tolerance and yield. “Biotechnologists would seek to identify such genes and upregulate them in vegetation,” she said. Similarly, the effect of temperature on the lifecycle of pests could be studied. The further prices and benefits of imposing climate good solutions and the losses due to no longer imposing them could be studied in an financial perspective, she said.


The analysis could be performed within the state-level for main vegetation equivalent to paddy, maize, millets and sorghum. From May, TNAU would additionally behavior capacity construction programmes on climate analysis for team of workers from institutions around the nation.
