Hyderabad: Agricultural scientists, including those from the City-Based Central Research Institute (Crida) have predicted a decline in potential rice from an average of 3.62 tons per hectare to 3.11 tons per hectare by 2030 and 3.02 tons per hectare 2040 -and thanks to climate change and global warming.
There will also be reducing rice yields that are cultivated in rainfed conditions from 2.13 tons per hectare to 1.67 tons per hectare in 2030 and to 1.62 tons per hectare in the 2040s.
This study stretched 17 countries including Telangana and Andhra Pradesh.
Scientists arrive at the potential decrease in rice yields based on 6.2 million simulations of climate change and global warming.
Andhra Pradesh and Telangana will be beaten hard because they are mainly rice producing countries.
Nizamabad District in Telangana, along with Krishna and Godavari Delta in the AP, is considered a bowl of South Indian rice.
Agricultural scientists have also projected a decline in rice yields based on temperature increases with various degrees.
They warn that rice yields are expected to decrease by 30 to 60% of study countries as part of research.
The results of the study were published in the recent edition of science publications, water journals and climate change.
According to projection, the average rainfed gap in rice yield will be 1.49 tons per hectare in the future.
“The trend of seasonal climate variables showed an expected increase in maximum temperatures, minimum temperatures and rainfall, and trends for decreasing solar radiation in the future IE 2030 and 2040s over the study area.
As a result, limited spatial water potential rice results are expected to decrease from 3.62 tons per hectare in the historical period to 3.11 tons per hectare and 3.02 tons per hectare each of the 2030s and 2040s, “research predictions.
Further scientists said there would be an increase in gaps by 20.9% and 22.2% in 2030 and 2040.
GAP The results of stagnant in 29.7% and 26.5% and reduced the gap of results at 49.4% and 51.3% of the study area of ​​2030 and 2040.
The researchers said their findings “contributed to understanding the consequences of climate change in the gap of rice yields and food security problems in India, which is important for planning agricultural policies and selection of mitigation strategies to reduce the gap in rice products”.
They said their research studies also had the potential to be translated for other parts of the world, and for other plants to develop adaptation strategies to reduce crop gaps to improve regional and global food security.
Other research studies by national innovation in climate resiliation agriculture (NICRA) where Crida is a research body, projects the potential for reducing Kharif rice results in the extreme climate.
