    IMPACT OF ENVIRONMENTAL EDUCATION AMONG THE HIGHER EDUCATION STUDENTS OF COIMBATORE DISTRICT
    (SACON, 2017) Chandran, R; Azeez, P A
    In the last couple of decades world over there is serious deliberations on the need for pro-active participation of the public, various social segments, and persons from various walks of life in conservation of the Environment and on identifying effective strategy to accomplish that. It is well recognized that conviction, at the grass root level, on the cruciality of environmental conservation is essential for wide and involved participation of public. Environmental education (EE), especially among the youngsters, to a great extent fulfills that need and facilitates educated decision-making among the public on issues related to environment. Thus, the main goal of EE is developing a world population that is aware of and concerned about the environment and its associated problems and which has the knowledge, skills, attitudes, motivation and commitment to work individually and collectively toward solutions of current problems and prevention of new ones.

    Particulate air pollution data for Coimbatore, India: real time monitoring and modeling with data-interoperability measures
    (SACON, 2016) Nisadh, K A; Azeez, P A
    Particulate air pollution is a major health burden and environmental concern in urban areas. As a serious health problem in urban areas, current intervention measures has to be sufficiently refined for urgent and sustainable management. Data intensive approach can gives tools to integrate diverse data sources for deriving decision-making information and improved applications for adaptive management of pollution. However lack of spatio-temporally relevant and reliable data on particulate pollution and the data existing in non-interoperable formats to a great extent hampers knowledge generation for effective control of pollution and management of air quality. The current study focused on developing basic tools for data intensive approach in a second tier urban centre of India. The study intends to explore an affordable real time air quality information systems focusing on Coimbatore, a fast growing and second tier urban center in the state of Tamil Nadu, India and its surroundings as the study area. The major objectives of the study were (1) to develop a real time particulate pollution monitoring system using low cost commodity sensors and assess its effectiveness in the study area, (2) attempt a real time particulate pollution modeling system for the study area using WRF-CHEM, addressing its computational requirements, and (3) demonstrate application of interoperability measures on real time particulate pollution data.

    Status and Ecology of House Sparrow Passer domesticus along an urban to rural gradient in Coimbatore, India
    (SACON, 2011) Dhanya, R; Azeez, P A
    In due course of the evolution of human civilisation, from their nomadic to the resident lifestyle, they were industrious agents of change. Their behaviours changed ecological processes in agglomerates of residences and trades, in cities and as well as in other areas (Vitousek et al. 1997). As the human population rise, infrastructure grows up; urbanisation spreads and increasingly affects biodiversity (Blair 2004). Human activities in the form of land use changes, urbanisation and infrastructure developments are considered major threats to biodiversity (Gontier 2008). This in turn results in the loss and fragmentation of natural habitats, thereby threatening populations of local species and ultimately biodiversity (Saunders et al. 1991). Urban development produces the greatest local extinction rates and eliminates the majority of the species (Vale and Vale 1976, Marzluff 2001, Czech et al. 2000). This replacement brings in the process of biotic Homogenisation that threatens to reduce the biological uniqueness of local ecosystems (Blair 2001). The loss and fragmentation of valuable habitats influences the long-term viability of species populations, which may ultimately become extinct at the local or regional scale

    Air Quality of Coimbatore with Emphasis on Respirable Suspended Particulate Matter
    (SACON, 2002) Mohanraj, R; Azeez, P A
    Particulate matter (PM), a complex mixture of organic and inorganic substances is an ubiquitous air pollutant, contributed by both natural and anthropogenic sources. Ever since the advent of industrial era, anthropogenic sources of PM have been increasing rapidly. Increasing amounts of such potentially harmful particles being emitted into the atmosphere on a global scale has resulted in damage to the health and environment. Recently it is also reported that soot particles have a heating effect to the atmosphere. Such heating effect can have wide implications on various systems of earth including climate. PM in the atmosphere is categorized according to size because of different health impacts from particles of different diameters. PM with diameters of less than 50 pm are generally classified as Total suspended Particulate Matter (TSPM). Particles that are greater than 50 pm in diameter do not remain in the atmosphere for appreciable lengths of time and present no health risk. Particulates with a diameter less than 10 pm defined as PM 10 or Respirable Suspended Particulate Matter (RSPM), enter the respiratory system and may become lodged in the alveoli resulting in wide range health effects including cancer and heart failures. PM 10 has the potential to travel long distances and cause cumulative effects. Other hazardous air pollutants may adhere to these particles, increasing their toxicity. These particles on wet and dry deposition are known to pollute local, regional and global land and water resources.
