Bio-diversity
Characterization at Landscape level
We live in a landscape and fulfill our most
of the needs from its diversity. The increasing human population
satisfies their demand from various kinds of economic activities
carried out on the landscape, which ultimately along with various
geomorphic and biological processes give the birth of spatial and
structural changes.
The landscape change spatially and temporally due to the tectonic,
climate, biotic interaction with the environment. Of these the influences
brought by the human beings through indiscriminate utilization of
the natural resources and action without due regards to the environmental
impacts and sustainable development can be prevented and controlled
by scientific and technical know how, if proper data base is built.
The landscape characterization has been proved to be effective for
evaluation of landscape ecologically, and for the sustainable utilization
of natural resources, to maintain the essential ecological processes
and the life support system, to conserve the biological diversity
and to prioritize the conservation areas and creation of network
of protected areas.
The landscape structure, function and change analyzed using the
patch elements. The patch characteristics viz., porosity, patchiness,
interspersion, juxtaposition etc are analyzed and patch dynamics
are studied using the GIS by developing the software for East Godavari
district. The basic inputs are vegetation type and density, roads,
villages, contours etc. These parameters are used to develop the
disturbance index. The ring and edge entities are studied. Various
indices of biodiversity generated. The contagion, association etc
are studied. This in combination with the other information like
species economic and scientific value etc can be used to derive
the ecosystem uniqueness and biodiversity richness value. It can
be used to study the fragmentation and disturbance indices for the
attention of policy makers and the managers of the ecosystems and
also for Study of landscape patterns for better management practices.
These indices can be used for prioritization of natural and biological
conservation areas and creation network of protected areas for present
and future generations, to follow the WCS and NCS. It also helps
in Acquisition and preparation of long term sets for perception
of global climatic change, deforestation, forest dieback, desertification,
acid precipitation etc., for management intervention. It also helps
in study of inter & inter - specific competition among species
using proximity analysis segregation and disturbance regime.
The software customization for biodiversity characterization is
under progress for generating the biodiversity indices, and can
be applied to all the areas.
