Telangana Hazard Mitigation Project - Prioritization of Shelter Belt Plantation Areas:

Geomatics center, Telangana Forest Department in collaboration with Forestry & Ecology Division, NRSA prepared a working plan for shelterbelt development program under Telangana Hazard Mitigation Project to prevent and mitigate the catastrophes in the form of cyclonic hazards along entire east-coast of Telangana. Remote Sensing data and Census data were taken as input databases and also the topography, soil, geology & geo-morphology etc., themes as other inputs and Geographic Information System as a tool by overlaying various themes to prioritize areas for establishing and for development of shelterbelts. The priorities were given by taking the land use and land cover pattern, population, slope and previous history of cyclone hazards into the consideration.

Inputs to Plans:

Geomatics is used as a tool in preparation of Forest Working Plans of divisions in the state by providing various inputs. The inputs like forest boundaries, stream network, contours, roads, villages, forest cover etc., and derived layers from these are vital in various levels of planning i.e., strategic, management and operational as well as the micro plans of JFM.
Pre-inventory/inventory points are generated based on the classified map by way of Probability Proportionate Stratified Random Sampling for growing stock estimation. The sampling intensity is based on the variance in population in each stratum (canopy density class). Forty five plots of 0.1 Ha each in every Division @ 15 plots in each density class were generated randomly. Basing on the variance in population, the final inventory points were generated through Optimal sample size determination procedure and overlaid on topomaps and given to field people to conduct the detailed inventory.

The final inventory is under progress and the information gives the Statistics of growth and yield of growing stock, and also the Status of Forest and Potentiality of the forest area in the division. Accurate stock maps and other information dependant maps will be generated with the help of RS, GIS and statistical inputs (inventory data). Once the stock maps are prepared, it is easy to derive working circles with help of other collateral information. Basing on the working circles treatment practices can be designed. GIS will be used for area calculation, statistics generation and for final output map making. It makes the task more accurate, fast and simpler.

The inputs maps for all the CFM areas are generated by overlaying the random points generated using the probability proportionate stratified random sampling, on the topomaps along with related information. These points form permanent inventory points.
