The water quality was investigated for a period of six months from January to June 2015. The surface water samples were collected monthly from the three sites of Tirur River namely Tirur, K eywo rd s Thazhepalam and Parapadi of Tirur River, which lies between 750 55′ and 750 54′ 0 0 East longitude and 10 55′ and 10 54′ North latitudes. The physico-chemical Physico-chemical parameters analyzed were temperature, pH, acidity, alkalinity, total hardness, parameters, calcium hardness , magnesium hardness, chloride, salinity, dissolved oxygen (DO), Tirur - Ponnani River, River nitrate, sulphate, biochemical oxygen demand (BOD) and chemical oxygen pollution, demand (COD) and their correlations were discussed. The physico-chemical Malappuram parameters showed distinct seasonal and spatial fluctuations. 57 species of District, Kerala. phytoplankton were identified during the period of study from the Tirur River which come under 29 genera belonging to four taxonomic classes namely Article Info Cyanophyta, Chlorophyta, Bacillariophyta and Euglenophyta. The salinity was Accepted: higher in Tirur River during the period of study and the diversity of phytoplankton 12 June 2016 showed a number of marine diatoms during the pre-monsoon season. The class Available Online: Bacillariophyceae (Diatoms) was the dominant group of algae in all the three sites 10 July 2016 of Tirur River throughout the period of study. The present study identified 11 pollution tolerant algal genera namely Lyngbya, Oscillatoria, Cocconeis, Cyclotella, Cymbella, Melosira, Navicula, Nitzschia, Stauroneis, Synedra and Euglena and it revealed that the quality of the water was deteriorated at all the selected three sites in the Tirur River and are polluted due to human interventions. The analysis of physico-chemical parameters indicated that the water quality of Tirur River was deteriorated at all the three sites studied during the period of study and the contaminants came from fish market and railway station. Introduction The phytoplankton helps in the on the lower level of the food chain will also determination of the impact of pollutants on have consequence on the higher level the aquatic environment because any effect organisms.

  • Understanding REPORT of the WESTERNGHATS ECOLOGY EXPERT PANEL
    Understanding REPORT OF THE WESTERNGHATS ECOLOGY EXPERT PANEL KERALA PERSPECTIVE KERALA STATE BIODIVERSITY BOARD Preface The Western Ghats Ecology Expert Panel report and subsequent heritage tag accorded by UNESCO has brought cheers to environmental NGOs and local communities while creating apprehensions among some others. The Kerala State Biodiversity Board has taken an initiative to translate the report to a Kerala perspective so that the stakeholders are rightly informed. We need to realise that the whole ecosystem from Agasthyamala in the South to Parambikulam in the North along the Western Ghats in Kerala needs to be protected. The Western Ghats is a continuous entity and therefore all the 6 states should adopt a holistic approach to its preservation. The attempt by KSBB is in that direction so that the people of Kerala along with the political decision makers are sensitized to the need of Western Ghats protection for the survival of themselves. The Kerala-centric report now available in the website of KSBB is expected to evolve consensus of people from all walks of life towards environmental conservation and Green planning. Dr. Oommen V. Oommen (Chairman, KSBB) EDITORIAL Western Ghats is considered to be one of the eight hottest hot spots of biodiversity in the World and an ecologically sensitive area. The vegetation has reached its highest diversity towards the southern tip in Kerala with its high statured, rich tropical rain fores ts. But several factors have led to the disturbance of this delicate ecosystem and this has necessitated conservation of the Ghats and sustainable use of its resources. With this objective Western Ghats Ecology Expert Panel was constituted by the Ministry of Environment and Forests (MoEF) comprising of 14 members and chaired by Prof.

Two decades of indiscriminate exploitation for the pet trade, restricted range, fragmented populations and continuing decline in quality of habitats has resulted in their ‘Endangered’ listing. Here, we tested whether the isolated RLTB populations demonstrated considerable variation qualifying to be considered as distinct conservation targets. Multivariate morphometric analysis using 24 size-adjusted characters delineated all allopatric populations. Similarly, the species-tree highlighted a phylogeny with 12 distinct RLTB lineages corresponding to each of the different riverine populations.

Liji Samuel* & Dr. Prasad A. K.** *Research Scholar, Department of Economics, University of Kerala Kariavattom Campus P.O., Thiruvananthapuram. **Associate Professor, Department of Economics, University of Kerala Kariavattom Campus P.O., Thiruvananthapuram. Received: June 25, 2018 Accepted: August 11, 2018 ABSTRACT Energy has been a key instrument in the development scenario of mankind. Energy resources are obtained from environmental resources, and used in different economic sectors in carrying out various activities. Production of energy directly depletes the environmental resources, and indirectly pollutes the biosphere. In Kerala, electricity is mainly produced from hydelsources. Sometimeshydroelectric dams cause flash flood and landslides. This paper attempts to analyse the social and environmental consequences of hydroelectric dams in Kerala Keywords: dams, hydroelectricity, environment Introduction Electric power industry has grown, since its origin around hundred years ago, into one of the most important sectors of our economy. It provides infrastructure for economic life, and it is a basic and essential overhead capital for economic development. It would be impossible to plan production and marketing process in the industrial or agricultural sectors without the availability of reliable and flexible energy resources in the form of electricity. Indeed, electricity is a universally accepted yardstick to measure the level of economic development of a country. Higher the level of electricity consumption, higher would be the percapitaGDP. In Kerala, electricity production mainly depends upon hydel resources.One of the peculiar aspects of the State is the network of river system originating from the Western Ghats, although majority of them are short rapid ones with low discharges.
