A large body of evidence has confirmed that the indoor air pollution (IAP) from biomass fuel use is a major cause of premature deaths, and acute and chronic diseases. Over 78% of Sri Lankans use biomass fuel for cooking, the major source of IAP in developing countries. We conducted a review of the available literature and data sources to profile biomass fuel use in Sri Lanka.
Most of the research on alpine treeline shift has primarily been based on field data with a limited geographical extent. Due to its synoptic view and historical records for a wide area, remote sensing is an important tool to study alpine treeline and changes in the recent past. This study confirms that there is an upward shift of vegetation in the alpine zone of the Himalayas. The mean upward shift of the treeline is found to be of the order of 388 ± 80 m.
The present study analyses the effect of a paper mill on epiphytic lichen communities in Barak Valley, Assam. Lichen thallus size, thallus number and frequency of occurrence, along with diversity of lichens at three levels (species, generic and family) are considered as variables to see the community composition across the distance from a paper mill.
This study evaluated the microbiological quality of treated and untreated water samples from urban and rural communities and examined the relationship between coliforms occurence & average water temperature and a comparison of the rainfall levels.
The Jawaharlal Nehru National Solar Mission (JNNSM) and the Gujarat Solar Policy have provided a large market for thin film technology. Until 2010, most of the country's solar energy development was dominated by off-grid systems based on crystalline silicon technology.
