The land use/land cover pattern of a region is an outcome of natural and socio-economic factors and their utilization by man in time and space. Land is becoming a scarce resource due to immense agricultural and demographic pressure. Remote sensing (RS) and geographic information systems (GIS) techniques provide effective tools for analyzing the land use dynamics of the region as well as for monitoring, mapping and management of natural resources. The objective of the present study is to analyze the land use/land cover dynamics from the year 1975 to 2012. The present study area is the eight nos. of blocks of Khordha district, which are coming under Chilika catchment. From those blocks Chilika and Tangi are coming as total area in the catchment but other six nos. of blocks are partly coming under catchment.

Ansupa, the so-called sister lake of Chilika once was looking like a heavenly picture gallery with small fishing boat on the blue waters and hills on the banks, birds of different colors and above all lotus and lilies. The lake is bounded by Saranda hills on its western side, Bishnupur hills on its northeast side and surrounded by villages like Subarnapur, Kadalibadi, etc. Previously during the high floods, the flood water of the river Mahanadi used to pass through the lake from its southeastern side driving away from the weeds through the south – western side. So, it was a process of natural deweeding. But, when the water enters into the lake, cannot be discharged due to the erection of embankment, silting up of the lake, etc. The Chilika Development Authority, which is under the Department of Forest and environment of Odisha has taken a very vital step to clear the weed from the lake for sustain the livelihood of the community by using an instrument Weed cuter under the project Integrated Coastal Zone Management of Odisha. Geospatial Technology has used for regular monitoring the successful management as a case study during the year 1999 to 2019.

The study area is the part of Outer channel of the Chilika lake which is situated within 19°39’56.682” to 19°43’20.555” N latitude and 85°31’35.575” to 85°36’16.924” E longitude. Three new inlets are open. Two inlets are in between the inlet “A” and “B” named “C” and “D” with the width of 249 Mt and 214 Mt, respectively.

In the present study, morphometric analysis of the Ansupa lake Catchment has been carried using earth observation data and geographical information system (GIS) techniques. The morphometric parameters considered for analysis includes the linear, areal and relief aspects of the basin. The study has strengthened in understanding the hydrological, geological and geomorphological characteristics of the Ansupa lake Catchment. This study attempts to perform the drainage analysis on a terrain model for Ansupa Catchment situated in Cuttack district of Odisha. It is a fresh water lake and there are a number of small lakes around it. The lake falls in Survey of India toposheet No. 73/H11 (1:50000) and 73H11NW (1:25,000). It is bounded by 20 ⁰ 26′06′′ to 20 ⁰ 28′03′′N latitude and 85 ⁰ 35′09′′ to 85 ⁰ 36′06′′ E longitude. The lake represents the characters of a typical ox-...

Lake shrinkage is another important ecological transformation. This may be due to several factors, both natural and human. The study area is Chilika Lake which is located at 19°27’58.081”N–19°53’24.438”N latitude and 85°6’5.301”E–85°40’36.149”E longitude on the east-coast of the state of Odisha, India. The objective is to prepare a database of the pre and post monsoon period water spread area of the lake from time series satellite imageries. The geospatial technique has emerged as the most important tool of a geographer to handle the spatio-temporal data. It is now widely used around the world to analyse physical as well as cultural geographical elements. The output will be utilized in several regional and micro level planning, monitoring and management for community development. Ke...

This has led to increased productivity and income. Training and holistic management along with aforestation programs has led to reduction of silt flow to the lake. The assessment revealed that land degradation in the drainage basin not only leads to enhanced silt flow into the lagoon but also causes poverty, due to low productivity in the drainage basin. The drainage basin management program is conceived as a long-term participatory process to achieve an environmentally, economically and socially sustainable management of water resources. The present study deals with periodic assessment and monitoring the vegetation cover of the Dengei pahad micro watershed, Khurda District, Odisha, using NDVI techniques. NDVI is the traditional vegetation index used by researchers for extracting vegetation ...

The sediment contributions from the rivers are deposited along the coast. The littoral drift deposition builds spits and bars at the river mouths especially at the southern side of the river mouths. The one of the study area is situated between 20°40’57.417”N and 20°45’49.947”N latitude and 87°1’5.576” E and 87°7’4.959”E longitude. Another is the Dr. Abdul Kalam Island, formerly known as Wheeler Island, an island off the coast. The Integrated Test Range missile testing facility is located on the island. In May 2013, increasing concern has been drawn to the change of the island's topography, owing to sand erosion. Since the island is technically a shoal, seawater frequently causes sand-shifting. The situation is being monitored by geological experts from National Institute of Ocean Technology and the DRDO.

The study area is Mahanadi estuary in the Kendrapara district which situated 20°16ʹ18.443ʹʹN to 20°32ʹ22.094ʹʹN latitude and 86°35ʹ25.115ʹʹE to 86°49ʹ38.818ʹʹE longitude in Kujanga block of Jagatsinghpur district and Mahakalpada block of Kendrapara district and the Hukitola Island which is situated in the Mahakalpada block. The objective of the study is to analyze the shifting the mouth of Mahanadi estuary and the geomorphological process of the Hukitola Island which is very dynamic. The study was taken during the year 1929 to 2015. According to Srinivasan et al., during the year 1952 to 1973, the mouth of Mahanadi estuary migrated northwards up to 4 km. The geo-spatial technique has emerged as the most important tool of a geographer to handle spatial data. This technique is now widely used around the world to analyse physical as well as cultural geographical ele...

Natural climate variability has always been a challenge to human livelihoods. Human-induced climate change, however, has added a complex new dimension to this challenge. Evidence suggests the natural climatic variability, compounded with climate change, will adversely affect millions of livelihoods around the world (IPCC, 2007a). Rural communities in the developing countries are expected to be affected more than those in developed countries because of their extensive dependence on climate-sensitive livelihood options and limited adaptive capacity to adapt to the changes. Although climate change is a global phenomenon, its manifestations and impacts vary locally, as do the adaptation capacities, preferences and strategies. Effective planning for climate change adaptation programming requires an assessment of local vulnerabilities to bridge the gap between community needs and priorities at the local level and policy processes at the higher level.

The study is about the Kadalibadi micro-watershed of Ansupa catchment and the micro-watershed, covering five nos. of villages (Kadalibadi, Podapada, Radhadarsanpur, Mahidharpur and Baidehipur). Remote sensing (RS) along with geographical information system (GIS) technologies has been successfully used to derive considerable accurate representation of various watershed delineation features. GIS techniques are characterized by very high accuracy of mapping and measurement, and have been proved to be a competent tool in morphometric analysis.
