Macrobenthos of the Shelf Waters of the West Coast of India

The work was carried out with an objective to know the quantitative and qualitative nature of the macrobenthos in relation to the existing hydrographical parameters and sediment characteristics. With the above two cruises were conducted to collect materials. Representative samples were collected from each degree square of the western continental shelf. The study deals with the hydrographic parameters. The bottom water temperature, salinity and dissolved oxygen were measured. The findings showed variations according to depth and latitude. The study gives the details of sediment characteristics of the study area. 7 different types of substrata were noticed. It also explains the macro faunal composition and diversity, and the standing stock of macrobenthos. The wet-weight and numerical abundance of macrobenthic groups are included. The thesis discusses the relation between hydrography and macrobenthos, and sediment characteristics and macrobenthos, based on the results obtained by statistical analysis of the data. It also investigates the relation between macrobenthos and fishery.

Distribution of Benthic In fauna in the Cochin Backwaters In Relation To Environmental Parameters

The study revealed stress and localized impact of industrial waste on the biota, predominance of stress tolerant species and low diversity in the vicinity of the effluent discharge point. These studies on impact of environmental parameters on the distribution of macrobenthos thus indicate the quantum of endurance warranted by the infauna to tide over the wide range of environmental stress. Low diversity and lower number of benthic fauna near discharge site can be attributed to the stress caused by cumulative toxic effects of effluents. The results of the physico-chemical parameters highlight the effects of pollution. The results of the study indicated the changes due to the large-scale movements of the estuarine water under the influence of tide, monsoon and land runoff coupled with its heterogenous nature owing to the effluent discharge from the industries

Legal Control of Industrial Pollution

Industries constitute the main spring of development. Without industrial development no country could reach a stage in which a decent living for its citizens would be achieved. Increasing production to meet the basic needs of society augmented scientific invention and machine oriented industrial order.Environmental pollution ls a burning global issue. It is more serious and dangerous than terrorism. Started with the discovery of fire and development of civilization. Pollution went unnoticed throughout the centuries of human growth until its adverse effects on human environment become explicit.National concern tor environment started in our country only atter the cause of protection of environment received global attention. At present legal control ot industrial pollution is in a scattered framework of piece meal processes with overlapping provisions and authorities.Environmental protection- should be an item not only in the concurrent list of schedule 7 to the Constitution but also in the list of matters entrusted to the panchayati institutions in the Schedule 11. It is heartening to note that so far as municipalities are concerned the Constitution of India lives up to the expectation. In the wake of New Industrial Policy based on liberalisation a long list of small scale industries fall outside the purview of environmental clearance. The Indian concept of environmental im»act assessment introduced under the Environment Act by notification excludes the entire gamut of small scale industries and r.elates only to scheduled industries covered by the notifica~ion. Most of them are subjected to ETA only it the investment goes above ~.50 crores. This provision dilutes the impact assessment considerably A mandatory impact assessment with public partiCipation and with provision for a review by specialized environmental courts will eliminate the possible evils of this judicial passiveness.

Economic Valuation of Coastal Wetlands: A Study of Cochin Back waters in Kerala

The major objective of this chapter was to estimate the indirect benefits provided by the Cochin wetlands to direct, indirect and non-user populations.This chapter gives the details of the Contingent valuation survey that was executed in the study area. Section one described the actual survey and its execution. Section two undertook a detailed discussion of the methodological issues involved in the survey. Section three contained some discussion on the study.This analysis has demonstrated the feasibility of extending the use of contingent valuation methods to local populations in developing countries like India. Certain issues emerge from these applications. Income is strongly related to willingness to pay in these surveys, yet income levels are often low.Secondly, education is not a factor that influences willingness to pay in the coastal belt very much. Rather, relation of individual occupation to any wetland based activity very much influenced their willingness to pay. The study revealed that people very much valued the indirect function performed by wetlands, in fact as much as they valued the direct benefits provided by the system. There still exist differences of opinions among experts when undertaking such valuation studies. However, in the absence of a better technique for valuing environmental services that have no markets, this is definitely a first step

Water characteristics and current structure of the intermediate waters in the arabian sea

At intermediate depths of the Arabian Sea, the circulation and characteristics of water are more influenced by the high saline waters from the north and low saline waters from the south of equator. The interaction of these waters which greatly differ in characteristics is less understood compared to that at the upper layers. An understanding of the nature of the intermediate waters is of vital importance not only because of the unusual characteristics of the waters but also due to the influx of the different water masses from the neighbouring Red Sea and Persian Gulf. Hence, in the present investigation, it is proposed to study the water characteristics and current structure of the intermediate waters in the Arabian Sea through the distribution of the water properties on the isanosteric surfaces of 100, 80, 60 and 4O—cl/t, vertical sections, and scatter diagrams An attempt is also made to present the potential vorticity between different steric levels to understand the circulation and mixing processes. Data collected during and subsequent to International Indian Ocean Expedition (IIOE) are used for this study. The thesis has been divided into six chapters with further sub divisions

An economic evaluation of industrial estates in kerala

A massive programme for the development of small scale industries in India known as ‘Industrial Estates Programme‘ was launched by the Government of India in 1955, This technique of industrialisation was recommended by the Small Scale Industries Board in 1955. The first industrial estate in India was set up at Rajkot (Gujarat) in September 1955 and the first shed allotted in December 1955. Since the Government of India entrusted the state governments with the responsibility of starting the estates, the Government of Kerala decided to start one industrial estate in each district during the second plan. It was envisaged that each district should have two industrial estates each, one as urban estate, the other as semi-urban or rural estate. This study attempts to make an economic evaluation of the Industrial estates programme in Kerala. It is based on a survey of all working industrial units in the 17 major industrial estates of Kerala.

Time and cost overruns of industrial projects in kerala

Poor project planning, implementation and control and the subsequent cost and time overruns are ubiquitous features that have been posing serious concern at all levels - state, national and international. It results in wastage of the nation's scarce resources and retards the socio-economic progress. Although several studies peripheral on project overruns have been made at the national level, no serious attempt has been made at the state level to identify the magnitude of overruns, their causes and impacts on industrial projects. The present study "Time and Cost Overruns of Industrial Projects in Kerala" is an earnest attempt to probe in depth the time and cost overruns and their impact on industrial projects. The study places emphasise on the identification of the real reasons behind the cost and time overruns. It also covers the present project management practices of industrial projects in Kerala.

A study of industrial co-operatives in kerala with special reference to modern small scale sector

The report of the Steering Committee of the Kerala State Planning Board for the preparation of the VIII five Year Plan on Industry and Hiningzslisted several factors inhibiting and promoting growth of small industrial units. Kerala's educated manpower, the native intelligence of the Keralites best suited for taking up logic—based professions and availability of a Hell—developed and broad~based physical infrastructure particularly in the transport and communications sectors, are a few of the positive factors identified. On the negative side, may be mentioned high wage rates, preference on the part of the educated for white collar Jobs, lack of entrepreneurship, paucity of essential resources for industrial use, high density of population and the distance factor which places Kerala away from the major domestic markets. In this context, it would appear that the industrial co-operative movement could possibly play a vital role in accelerating-the momentum of small industrial development of Kerala which has a Health of highly educated and skilled manpower. However, in spite of the encouragement extended by the Government, the movement does not seem to have.been picking up in the modern small scale sector. The present study is an attempt to analyse the factors that have affected the performance of the industrial co—operatives in the small scale industrial sector of Kerala.

Physical characteristics of the coastal waters off the south-west coast of india with an attempt to study the possible relationship with sardine mackerel and anchovy fisheries

The present study is aimed at observing the variations, in space and time, of see of the important hydrographic parameters such as sea water temperature, salinity and Resolved oxygen within the coastal waters along the south-west coast of Indiametween Ratnagiri (17°OO*N,73°20'E) and cape comorin ( 8°10'N,77°30*E). Specific data relating to the process of upwelling and sinking was collected mainly to evaluate the extent and intensity of the vertical mixing processes active in the area under study. The study also attempted possible correlations between the observed parameters and the occurrence and migrations of some of the major pelagic fishery resources such as sardine,mackerel and anchovy in the area under study
