Coastal erosion is one of the major and serious concerns for coastal communities residing in the low lying areas, especially near to estuary delta regions. These regions see lots of anthropogenic activities such as economic development, infrastructure and human settlement especially in rapidly developing countries such as India. Shoreline change is a natural process that occurs in coastal areas. But due to the stresses happening in the coast because of anthropogenic activities, understanding how shorelines change over time is important for sustainable management of coast. A crucial aspect of shoreline change monitoring is to identify the location and change over time which can be achieved by developing monitoring strategies using satellite remote sensing data. Performing shoreline change analysis using long term satellite records will help us to understand how shorelines respond to coastal development over time. In the present study we investigate shoreline erosion and accretion rate using three temporal Landsat scenes acquired over a thirty year period for the years 1988, 2000 and 2017. Digital Shoreline Change Analysis System (DSAS) an extension of ArcGIS software was used to compute rate of change statistics by calculating End Point Rate (EPR) values. We observed that Chilika coast is experiencing both erosion and accretion process with very high erosion rate of −13.6 m/yr and accretion of 13.5 m/yr, at Chilika Lake mouth. The average erosion and accretion rate of −1.13 m/yr and 1.41 m/yr were recorded for the study region.

India is the largest producer of milk at the global level. In India, development in dairying would have direct impact on the lives of 8.475 million people working in Indian dairy sector. The Dairy Industry as an important allied sector continues to provide additional income to lakhs of people who depend on dairy related activities. Milk is nutritionally rich food to meet the daily needs of people. In Tamil Nadu, AAVIN is the successful cooperative society which deals with milk procurement, processing and marketing the milk and its value added products. The main objective of the study focused on consumer response towards rise of Aavin milk price. This study was limited to Coimbatore city comprising of 100 sample respondents. The results of the study indicated that, majority of the sample respondents were affected by the rise in price, even though there was comparatively low shift to other brands. The sample respondents also reduced their purchase quantity of milk. Freshness, better quality and quantity were the major factors influenced them to purchase and consume the Aavin milk in a constant manner.

In today's world, people are more aware of the product they consumed. Consumers are mainly relying on their health consciousness. However, people nowadays shift their consumption towards the traditional forms of sugar as they have better nutritional compounds compared to the refined forms of sugar. Here sample respondents are taken based on the traceability of value chains of alternate forms of sugar (Jaggery and Khandsari sugar, Coconut sugar, and Palm sugar). The study was limited to 150 sample respondents in Erode, Tiruppur, Namakkal, and Coimbatore districts of Tamil Nadu where these sugars are transferred with all actors involved in the value chain with the help of markets.  Principal Component Analysis is used to analyze the major factor to influence the purchase of sugar. The approximate chi-square statistic (0.774) is also large (>0.50). These factors account for 66.43 percent of the variance in the data. The three components that have the Eigenvalue of 6.58, 2.17, and 1.20 showed the percentage of variance were 43.87, 14.50, and 8.05 respectively. Based on varimax rotation with Kaiser Normalisation, three factors have arrived. The major factors that influenced highly were Health and convenience factor (Issues in white sugar, taste, traditional sweetener, Health consciousness, and Quality), Branding (Price, service of the seller, texture, packaging, Colour, market cleaning, non-perishable and popularity) and the other factor influenced in a fewer way. The result of the study concluded that consumers were mainly oriented about their health conscious and shifting towards traditional based products. Promotional measures were taken to promote these kinds of sugar and aim to bring back the traditional forms of sugar with its innovative technology. Packaging may be improved with biodegradable bags.
