The state government has declared a report regarding the climate change in the state which can seriously affect the agriculture sector in Assam.
According to the report ,due to increase in both frequency and intensity of high temperature it is emerging as a potential threat to the sustainability of rice production, as because the Rice is a C3 plant and such plants grow in hot tropical conditions like in valleys of Assam. Thus its photosynthesis becomes inefficient with high temperature and, thus productivity will go down with high temperature due to climate change.
Another impact on agriculture is the Impact of Climate Change on shortage of water for cultivation in the sector. The report said that the emerging trends of rainfall indicate that the number of rainy days is decreasing and the number and extreme rainfall days are increasing and so has their intensity. With total rainfall increasing in most of the areas in Assam in the future, it is likely that runoff will be high. Due to high run off the seepage of water for ground water recharge will go down.
Another major important Impact of Climate Change on Agriculture is the soil health issue. The report pointed out that exploitation of ground water continuously at higher degrees would lead to soil health problems like acidity, alkalinity, elemental toxicity, etc in the state.
Changes in climate would shift the pattern and life cycles of various insects, pests and pathogens. Many non-pest insects of might turn to be normal pests while many existing ones might perish forever. These would lead to exploring of new resistant varieties and pest controlling methods,official report said
