The correct answer is D) All of the above.
Satellite imagery, weather stations, and groundwater monitoring are all used for drought monitoring in Telangana.
Satellite imagery can be used to track changes in vegetation cover, which can be an indicator of drought. Weather stations can be used to measure rainfall and temperature, which can also be used to track drought conditions. Groundwater monitoring can be used to measure the level of water in aquifers, which can be an indicator of how much water is available for use.
All of these technologies are important for drought monitoring in Telangana because they can provide different types of information about the drought. Satellite imagery can provide a broad overview of the drought, while weather stations and groundwater monitoring can provide more detailed information about specific areas. By using all of these technologies, it is possible to get a complete picture of the drought and to track its progress over time.
Here are some additional details about each of the technologies mentioned above:
- Satellite imagery: Satellites can be used to take pictures of the Earth’s surface from space. These pictures can be used to track changes in vegetation cover, which can be an indicator of drought. For example, if a satellite image shows that an area that was once green is now brown, this could be a sign that the area is experiencing drought.
- Weather stations: Weather stations are used to measure rainfall, temperature, and other weather conditions. This information can be used to track drought conditions. For example, if a weather station shows that an area has received less than average rainfall for several months, this could be a sign that the area is experiencing drought.
- Groundwater monitoring: Groundwater monitoring is used to measure the level of water in aquifers. Aquifers are underground layers of rock or sand that can store water. The level of water in an aquifer can be an indicator of how much water is available for use. For example, if a groundwater monitoring station shows that the level of water in an aquifer has decreased, this could be a sign that the area is experiencing drought.
