    Opis:
    Climate change has become a major concern to human society because of its potentially deleterious impact worldwide. The degree to which rainfall amounts vary across an area or through time is an important characteristic of the climate of an area. This subject area in meteorology is called "rainfall variability”. Changes in amount, intensity and frequency affect the environment and society. The annual rainfall varies from 864 mm to 3081 mm (146 years data) distribution, which has sight variation throughout the district. The study purposes to examine the relationship between rainfall and paddy production. Samplings from 100 households have been gathered by questionnaire survey as primary data and the secondary data has been collected Meteorological Department, Department of Agriculture and published research reports. 146 years rainfall data and 34 years paddy cultivation data has been utilized to analyse the result. Accurate statistical methods have been used to find the variability that includes correlation and trend analysis of 3, 5 years moving average of standard deviation. As the result, the study finds that through the 3, 5 years moving average had shown high drier seasons of the years. The paddy production was very high in Maha season but this was very low in Yala season because of the rainfall variability. By the correlation between rainfall and paddy production, the significant value is positive in Maha season and this is negative in Yala season. However, both are having the different significance each other. Thus, even the rainfall was highly influenced to the higher production, this is impossible in each time. Therefore, the development of irrigation tanks and channels, rainwater harvesting and proper management would be supported to more production in Yala season.

    Opis:
    Wetlands are normally deemed areas where water covers soil all or part of the time. Wetlands are important because they protect and improve water quality, provide fish and wildlife habitats, store floodwaters and maintain surface water flow during dry periods. According to the Ramsar convention, wetlands are defined as "Areas of marsh, fen, peat land or water, whether natural or artificial, permanent or temporary with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six meters." (Ramsar convention, 1971). In Ampara District of Eastern Province, Kalmunai Municipality, the Karaitivu and Nintavur areas have some significant quantities of wetlands. However, increased population, construction works, town expansion and negligence have generated considerable damage to these. Thus, this research was conducted to identify the negative human impact on these wetlands. In so-doing, the following objectives were met: ‘to find the challenges to wetland existence to note changes in the study area, to find the factors for the wetland deterioration and to suggest solutions to wetland conservation’. Primary and secondary data were used for this study. As primary data, questionnaire survey and direct observation were used. As secondary data, books, magazines, previous researches and statistics were used. The collected data were analyzed using SPSS and GIS software and suggest the practice of remedial measures such as creating proper waste management systems and enhancing the awareness of the value of the wetlands.

    Opis:
    A disaster is a sudden, calamitous event that seriously disrupts the functioning of a community or society and causes human, material, and economic or environmental losses that exceed the community's or society's ability to cope using its own resources. All over the world the impact of disaster is very challengeable. Sri Lanka is not except for it. Landslide, flood, tsunami, drought and accidents are in abundance. Considering the Landslide, Badulla District is often affected by the landslide disaster. Thus, this study aims for this study, primary and secondary data were used. MS Excel 2013 and Arc GIS 10.4 were used to analyze the study. The findings of the study, the cause of physical factors around 40% and around 60% of causes occurred by human factors of landslide. Identify the landslide area measures the landslide, collecting the reports of infrastructure and precautions of landslide are supporting to reduce the effect. When shows the maps using GIS technologies for this landslide area helping to move the people to safe zone. Depth roots plants should be planted in this area to capture the soil and rock that will prevent the slide. Reservoirs must be built after doing the geological examination and geomorphological examination. Using the screed concrete in the base of mountains and making the Gabion walls of the width and height of mountains help to prevent the slide. This method called Geo textile. These solution helps to control the effect from landslide.

    Opis:
    Rainfall is of primary importance to both the physical and cultural landscape of any region. The objective of this study is to find the trends for rainfall variability on climate change in Batticaloa District of Sri Lanka, by analyzing 146 years of monthly data of rainfall received during the period 1869-2014 from the meteorological station of the Department of Meteorology. Some studies attribute extreme events to rainfall variability due to climate change induced by global warming. However, there is a dearth of climatological studies addressing the trends in rainfall over Sri Lanka in support of such attribution. In our study, statistical analysis such as linear and standard deviation for 3 year, 5 year, 11 year and 21 year periods were utilized to examine periodic rainfall changes in both annual and seasonal contexts. The study finds that the 3, 5 year moving average shows high drier seasons, but the 11, 21 years moving average show higher wet seasons during the period of study. The changes of rainfall are known to have led to disasters such as flood and drought. Annual rainfall varies from 864 mm to 3081 mm, the distribution of which has sight variation throughout the district.

    Opis:
    Water is a lifeblood aspect of human being and without water, human being is impossible in the world. From time to time, people have consumed water from many sources and the ancient civilizations also emerged from river banks to meet the need of water. In this modern industrial world, technological advancements have enabled the pipe-borne water supply in widespread manner and it is not except to Sri Lanka too. Excessive consumption of water leads to water resource scarcity and hinders the even water supply to the people. In general context, water wastage is seen as ‘the consumption of excessive water for the routing needs’. In Sri Lanka, the provision of water for drinking and irrigation on a sustainable basis is a national priority (Central bank of Sri Lanka, 2005). Despite, the pipe-borne water supply is considered as a method to supply water for people who are not access to the water, it has many contemporary impacts on water quantity’s change and consumption pattern. Thus, this study was conducted to find the pipe-borne water consuption and its wastages in Panandura urban area. The objectives of this study are ‘to evaluate the change of the quantity of pipe-borne water consumption, to find the factors for the water wastage and finding the mechanisms to reduce the water wastage and propose the proper water management plans’. This study was conducted using the primary and secondary data. As primary data, discussion, questionnaires were used and as secondary data, reports from national water supply and drainage board, Divisional Secretariat reports, books, research papers, newspaper, magazines, websites, qualitative and quantitative tools were used. Based on the analysis and using the collected data, objectives were attained as population growth, rise in income level, modern machinery utilization, urbanization are the reasons for the change of pipe-borne water consumption. And also, the main factors for the water wastages are the pattern of the water consumption of residents, water leaks and dearth of awareness among residents. To reduce the over consumption and wastage, frequently check the water leaks in households, recycle the used water, to follow the rain water harvesting methods and to conduct the awareness programmes among people regarding the water saving and wastage, were suggested as recommendations and importance of water saving and managemet also stressed in this study considering our posterity.

    Opis:
    The island of Sri Lanka is free from serious natural hazards such as volcanic activity and earthquakes resulting from climatic extremes, but there are impacts of many natural disasters, such as landslides, floods and droughts, the intensity and frequency of which are increasing due to human interventions. Some areas of Sri Lanka are also periodically subject to cyclones that occur due to climatic conditions and geographical locations. Land degradation denotes all natural or anthropogenic processes that diminish or impair productivity of land. This occurs mainly through soil erosion, loss of organic matter and nutrients in the soil; salinization and large scale land degradation in Sri Lanka. Its manifestations today are heavy loss of soil, siltation in the water bodies, reservoirs and coastal waters, unplanned settlements, loss of arable land leading to declining productivity in agricultural lands and intensification of impacts of natural hazards such as flooding and landslides. Land degradation is a major problem in Eastern Coastal Area from Kalmunai MC, Karaitivu and Nintavur Divisional Secretariat Divisions (DSDs) of Ampara District. However, there is a considerable spatial heterogeneity exists within this area in terms of land use, topography, land management and socio-economic conditions. Therefore, land degradation assessment studies are very important for the sustainable development of the area. Considering the above background, this study was conducted with the objectives of developing a land degradation assessment model using a GIS based approach.

    Opis:
    In the global context, about 1.25 million people die each year as a result of road traffic crashes. Moreover, road traffic injuries are the leading cause of death among young people, aged 15–29 years. Furthermore, 90% of the world's road fatalities occur in low- and middle-income countries (WHO, 2017). In Sri Lanka, the accident rate is increasing rapidly. According to the transport and civil aviation report, 2801 deaths, 2590 fatal accidents, 13,095 minor accidents, and 7719 critical accidents occurred in Sri Lanka in 2015. The trend of the accidents has been increasing due to many factors. Physical features of the roads and roadsides, behaviour of drivers and pedestrians are the main influence on the occurrence of accidents. Central province has many accidents-prone areas due to its spatial and temporal patterns. Landform and climatic factors such as fog, snow and rainfall trigger accident potentials. Therefore, this study, “Spatial and temporal patterns of road accidents and their challenges: a study on Nuwara-Eliya District” investigates reasons for the enhanced rate of traffic mishaps. This is the first such study of this phenomenon. Herein, we used primary and secondary data. The results indicate that physical features are mainly to blame.

    The major objective of this study is to identify the flood severity level of the study area using GIS applications. By employing this map, safer habitation zones were established. Direct personal observation and face-to-face interview was done to gather the primary data and Disaster Management center reports, Census reports of Sri Lanka, images and published research reports were used as secondary data. The severity level of flooding in this area was analyzed using SRTM imagery in ArcGIS and overlaid on a Google Earth pro map. The findings of the study established that the highly affected area consisted of around 8.953003 sq·km, the moderately affected area was around 9.190781 sq·km and the lowly affected area was approximately 9.31039 sq·km within the study area. The major causes for flood disaster in this area are the lack of drainage systems in some potential flood regions, the low landscape, poorly maintained drainage systems and the geographical arrangement of the road network. By creating this map, the inhabitants will be aware of danger areas and can relocate accordingly [3, 5-9].

    Urban population refers to people living in urban areas as defined by national statistical offices. It is calculated using World Bank population estimates and urban ratios from the United Nations World Urbanization Prospects. Aggregation of urban and rural population may not add up to total population because of different country coverages. The study based on the Kalmunai MC area and the main objective of this study is to identify the emerging challenges of urbanization in the study area. The study used the methodologies are primary data collection as questionnaire, interview, observation and the secondary data collection and SWOT analysis to made for getting the better result. The study finds that the SWOT analysis process provided a number of results and ideas for future planning. Collecting the results around themes has highlighted the breadth of ideas within KMC. A number of common issues emerged which require immediate action and clearly relate to developing KMC as a resilient urban. However, to generate energy requires heap quantities of plastic wastage and as a result of the process a byproduct of methane will be produced. Nevertheless, this process is not much financially viable as the quantities are limited in Sri Lanka. Control of water pollution is the demand of the day cooperation of the common man, social organizations, natural government and non -governmental organizations; is required for controlling water pollution through different curative measures. Domestic waste and sewage may treat before following them directly in drinking water sources.
