TEA GARDENS INVENTORYAND MANAGEMENT
· Extent of area under tea
cultivation with location on
1:10,000 scale including small
growers
· Mapping of garden land-use
with sections overlaid
· Identification of eroded,
degraded, uprooted and newly
planted areas
· Spatial variability of crown
densities of shade trees
· Generation of Tea garden MIS
with data entry module
· Generation of Tea GIS-MIS
Portal with hosts of facilities
for tea garden management
MAJOR HIGHLIGHTSTea is one of the most popular stable beverages in India and constitutes 21% of global area and 23% of world tea production. With an annual export of about 193 million kg, tea is a major foreign exchange earner. Maintaining the quality and targeted export of tea require reliable, periodic and latest information about the extent and condition of tea bushes in space and time.
Tea Board of India has taken a major initiative towards creation of tea garden inventory including small growers, monitoring of uprooted and replanted areas using geospatial technology to foster better linkages across all the stakeholders. The main objective of the project is to strengthen the Tea Board, Tea Research Association, Tea Gardens and Tea Industries by adopting geospatial technologies for better coordination, garden management and informed decision making at Tea Board level.
MAJOR BENEFITS
· Better linkage among Tea
Board of India, large gardens,
bought leaf factories, small
growers, and Industry
· Monitoring of uprooting and
re-planting activities towards
rejuvenation over a large area
with minimum effort and
manpower
