Context
Ministry of Environment, Forest, and Climate Change released the Detailed Project Reports (DPRs) of LiDAR-based survey of forest areas in ten states namely Assam, Bihar, Chhatisgarh, Goa, Jharkhand, Madhya Pradesh, Maharashtra, Manipur, Nagaland, and Tripura.
About the LIDAR survey of forest areas
- The projectstudy is awarded by WAPCOS, a PSU under the aegis of the Ministry of Jal Shakti.
- The Detailed Project Reports (DPRs) were formed using the LiDAR technology.
- The DPR’s were produced using LiDAR technology in which the 3-D(three-dimensional) DEM (Digital Elevation Model), imagery, and layers of the project areas are used.
Significance of study:
- The project will help augment water and fodder in jungles areas. It will -
- reduce human-animal conflict
- help in groundwater recharge
- help local communities
- state forest departments to use CAMPA funds
- The project reports will help recommend the micro soil and water conservation structures consistent with site-specific geography, topography, and soil characteristics.
- It will recommend different types of Soil & Water conservation structures such as Anicut, Gabion, Gully Plug, Mini percolation tank, Percolation Tank, Field bund, Sunken pond, Farm pond, etc.
- These structures will help in catching the rainwater and prevent stream runoff, which will help in recharging Groundwater.
LiDAR technology
- Lidar stands for Light Detection and Ranging.
- It is a remote sensing method.
- It uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth.
- These light pulses—combined with other data recorded by the airborne system — generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.
- Lidar systems allow scientists and mapping professionals to examine both natural and manmade environments with accuracy, precision, and flexibility.
