    Indian subcontinent is highly vulnerable to major natural disasters such as earthquakes, cyclones, floods, droughts, landslides and bushfires. Tsunami, which is a recent addition to this list, had occurred in the early morning of 26th December 2004, after a massive earthquake of 9.2 magnitude on the Richter scale in Andaman & Nicobar islands, resulting in the submergence of large area of farmland, and subsequent drying up of water bodies. It caused moisture stress for the standing crops, livestock and fisheries and affected the livelihood of the people to a large extent. In this context, the present study has been carried out to make the socio-economic impact assessment of livelihood security in agriculture, animal husbandry and aquaculture on the tsunami-hit lands of Andaman. Data have been collected from 150 sample respondents and the survey has been conducted for two periods, pre-tsunami and post-tsunami. The results have indicated that tsunami has ravaged the households, standing crops, farm inputs such as seed, feed and implements, livestock and poultry population, their sheds, fish ponds, etc., thereby affecting the basic livelihood security of the people in Andaman. The rehabilitation measures taken by the government and NGOs have improved their livelihoods by reviving agriculture considerably in the subsequent years and by creating employment opportunities in various farm and non-farm activities. The paper has suggested creating profitable livelihood security to vulnerable sections of the society in the existing socio-economic penury with holistic intervention of the community, government and NGOs.Agricultural and Food Policy,

    Overseas recruitment in India : structures, practices and remedies

    Get PDF
    This paper is drawn from an exploratory study aimed at assessing the efficiency of the existing institution for governing labour emigration in India with special reference to the overseas recruitment system. It traces the evolution of the current institution from the colonial times and foregrounds its discriminatory rationalities engendering enormous social cost. It tracks the difference between emigration through social network and recruiting agents and looks at the difference of cost and risk involved. By focusing on the unskilled and semi-skilled emigrations from India, the paper makes an endeavour to determine the discrepancy between the legal/policy structures and the prevailing practices of overseas recruitment, including strategies of circumventing legality. Drawing inputs from major stakeholders like intending emigrants, return emigrants, emigrant households, recruiting agents, Protectors of Emigrants, foreign employers, emigrant labourers and Indian Missions in select destination countries, it assesses the transaction costs of the present institution, identifies its major inadequacies and make recommendations for an alternative institutional framework that can effectively counter the many and varied illegitimate and dishonest activities which have sprung up in the field of emigration and ensure ethical practices in India’s overseas recruitment sector. Key words: emigration, recruitment, institution, social cost, transaction cost, social network, legality/illegality, protection, ECR/ ECNR JEL Classification : J21, J2

    Mangroves are one among the most productive ecosystem which provide a wide range of services to the coastal people, which includes the provision of food and timber products and coastal defense services by reducing risk from coastal hazards. Several research found that mangrove forests have been degraded throughout the world since 80s onwards due to anthropogenic factors and India is no exception for the same. The current study was conducted in the Krishna’s wetland, which is located in Krishna district of Andhra Pradesh (AP), South India, India. The Mangroves of Krishna is second largest mangrove ecosystem in AP, fifth in East coast, eighth in India and it is rich in biodiversity but highly vulnerable because of anthropogenic and natural factors which makes this study area very scared. Information on Krishna mangroves and their geospatial information are owned by different institutions to build this geospatial dataset as open to access everyone. The WebGIS is a latest advancement and hybrid of GIS and Internet technologies for the dissemination of the geospatial datasets and its variations through the web. The main objective of the current study is to develop and demonstrate a WebGIS using open source software and integrate geospatial datasets of the mangroves of Krishna into WebGIS platform and to analyse and assess areas that are degraded by influenced parameters and in need of sustainable management.The result revealed that the area of mangroves in Krishna was decreased from 2,454 ha in 1990 to 1,363 ha in 2000 to 1,339 ha in 2011. On the other hand the areas of mangroves in the Krishna delta were increased to about 678 ha from 1990 to 2000 and 2,230 ha from 2000 to 2011. It may be pointed out that the variation in mangrove covers in the study area due to land use conversion for different purposes and mangroves provides coastal defense services by reduce risk of coastal hazards. It is may be concluded that this WebGIS study is very useful and unique because it is sharing data through internet to everyone as it save money, time and data duplication, which are needed to different stakeholders such as researchers, decision makers, planners for the sustainable management of mangrove ecosystem

    A Pragmatic Approach Towards the Manufacture of Wet-White Leathers Using a Bio-Polymeric Tanning System

    Content: Different tanning materials endow leather with varying colors observable in undyed leathers. Periodateoxidized starch tanned leathers have a yellow tinge or light brown color and get darker with age. The color change in situ is ascribable to iodate ions that are byproducts of periodate oxidation. Iodate ions undergo reduction to form iodine molecules that are yellow or brown in low or at higher concentrations. This study focuses on the removal of iodate ions from Dialdehyde Tapioca Starch (DTS) using a simple precipitation method. Preparation of DTS is by periodate oxidation and precipitation of iodate ions using an inorganic precipitant. The experiments for manufacturing wet-white leathers used pickled goatskins and DTS (unmodified and modified) tanning agents at various percentages based on pelt weight. Glutaraldehyde (GTA) tanning was the control. The percentage removal of iodate ions in modified DTS was 98%. Both unmodified and modified DTS had an aldehyde content of 70%. FT-IR and 1H-NMR confirmed the aldehyde groups. GTA, unmodified, and modified DTS tanned leathers had shrinkage temperatures of 80, 87, and 89°C, respectively. The physico-mechanical properties of the control and experimental leathers are comparable. GTA tanned leather had the typical brown color associated with GTA tannages. The ‘b’ color value of unmodified DTS tanned leather was high confirming yellowing of leathers upon ageing. Wet-white leather tanned with modified DTS had no discernible color change. Analysis of the spent tan liquor shows a reduction in the BOD, COD, TS, and TDS load when compared to GTA tanning system evincing the biodegradability of DTS. This study has overcome the drawback associated with periodate-oxidized starch tanning agents, viz. leather darkening over time, considering the chemical and physico-mechanical properties of the resultant leathers. The novel iodate free DTS can be scaled-up for commercial availability. Take-Away: Removal of iodate ions from periodate-oxidized starch before its use as a tanning agent is imperative to avoid leather color change over time. This study reports the successful removal of iodate ions from Dialdehyde Tapioca Starch (DTS). Wet-white leather tanned with the modified DTS had no observable color change upon ageing
