If one needs to irrigate all the land in Vanaparthy, how many wells would be required?
Though the number of wells is less in Wanaparthy, the area under irrigation is more as compared to Vaddicherla. How is this possible?
Do you think the area under irrigation will change due to increase in population?
The change in area under cultivation, percentage change in number of wells and cropping pattern in 5 years as narrated by the people has been presented in table-2.
The population in the villages has also gone up in a period of 5 years by nearly 10%.
K stands for Kharif while R stands for Rabi. Negative values indicate loss/ decline, while positive ones show gain/rise.
If the number of wells is 155 now, what was it 5 years back? What does ‘decline in number of wells’ represents?
How would crops be affected due to decline in the number of wells? Compare table 1and2 and state what
they tell us about the area under irrigation in both the villages?
Which village do you think is more affected?
What is the change in types of crops grown in the villages?
Of late, most of the open dug wells were converted into bore wells that could reach greater depths of ground water zones and would also reduce loss of water by surface evaporation.Most of the open wells have dried up and water tables have gone down substantially during the last 5 years. During this time, 85 percent of the wells, mostly open, have dried-up in Vaddicherla while 45 percent of the wells dried-up in Wanaparthy.
If 45 percent of wells have dried up in Wanaparthy, and there is 39 percent decline in number of wells, what percentage of wells do you think have been converted to bore wells?
