Item The Potential of Use Slope Gradient as a Criterion for Demarcating Agro Ecological Zones of Wet Zone, Sri Lanka: With Special Reference to Kegalle District(International Postgraduate Research Conference 2019, Faculty of Graduate Studies, University of Kelaniya, Sri Lanka, 2019) Silva, T.M.; Sakalasooriya, N.This study is focused to introduce the importance of slope gradient for existing criterion for demarcating agro ecological zones of the Wet Climatic Zone (WCZ). The case is special reference to Kegalle District. There are 46 agro ecological zones in Sri Lanka and those defines with considering similar climatic variations, soil condition as a major factor and beyond this stage, it has been concerned elevation regarded from the mean sea level (MSL). Then focus either level of precipitation and spatial changes or soil types when constant level precipitation with vary of soil types. This zonation is the major decision of agriculture; it is a major economic activity, which is majority of local population engaged. Apart from that, commercial and domestic agriculture is the backbone for cultural aspects of traditions Sri Lankan society. Agriculture is playing a key role of land use activities with dynamic scenarios plus unplanned land use and land cover changes are key roles to enhance disaster risk specially the WC. Consequently, there is essential to apply better land use practices including agriculture for the disaster risk reduction. This study points out that the slope gradient is an important factor for demarcating agro ecological zones in WCZ and the study recommends for applying micro level implementation for agriculture decision-making to risk areas of WCZ. Kegalle District is a one of high disaster risk district for landslide with identified risky and dynamic land use practices. The study based on spatial analysis with the secondary data collected from Land use and Policy Planning Department (LUPPD) and Department of Survey, Sri Lanka. Then, applied relevant geospatial techniques to manipulate the data for the research purpose. Selected manmade agriculture (MMALs) land covers in 1998 and 2016 as tea, home garden and rubber cultivation were concerned in whole Kegalle District. Arc Map 10.1 is the main Geographic Information System (GIS) for apply relevant Geoprocessing techniques. Couple of slope gradients selected here according to the LUPPD as 30 – 60% gradient use under proper soil conservation methods and more than 60% slope gradient keep with natural vegetation. The results show the MMALs has temporal changes with drastically increasing even in the slopes of more than 60% within last 50 years of period. This situation alarming to consider the slope gradient use as a criterion for demarcating agro ecological zones of WCZ with relevant conditionsItem An Analysis on the Impact of SMS News Alerts the Mismanaging Critical Environmental Attributes Sequential Pre-Disaster Warnings(19th Conference on Postgraduate Research, International Postgraduate Research Conference 2018, Faculty of Graduate Studies,University of Kelaniya, Sri Lanka, 2018) Dahanayaka, T.Sri Lanka has been facing natural disasters like floods, landslides and etc, for a long time. A common feature of all disasters experienced in Sri Lanka is that they emanate from mismanaging the critical environmental attributes of the country by the Government and the people alike. Sri Lanka’s environmental resources such as forests, water, rivers and wetlands deserve careful attention and protection as they form the basis of life of a nation. Severe deforestation still occurs in Sri Lanka and the UN estimated that 8,000 ha of forest are cleared every year even now. Corruption, mismanagement and covert and overt support by politicians exacerbate this destruction. Climate change, droughts and floods are closely related to deforestation and people and politicians are all culpable in this tragedy. Ancient people could find out disasters by observing the sky or environmental changes or behavioral of the animals. After that the department of Meteorology issues early warning to the public using electronic media before disasters occur. Electronic media adverted their excessive biography for communicable aspect to all people in one time about pre – Disaster warnings. There are many electronic media activated SMS News Alerts system via mobile phones. People can get breaking news direct to their phone via SMS, or they can call to hear about the latest events. This essential service helps to people keep in touch with what’s happening in Sri Lanka and around the world in the language of their choice. News Alert mean; state of careful watching and readiness especially for danger or opportunity, an alarm or other signal of danger, a state of careful watching and readiness especially for danger or opportunity. This research attempts to find out the potential of SMS News Alert in the communication of pre disaster warnings to the public. Although this is the main objective, it also tries to find out a what Sensory SMS News Alert System has spread in Sri Lanka. Methods like questionnaire and Interviews have been used to achieve these objectives. Hambantota, Matara, Kalutara and Anuradhapura districts selected in order of priority based on frequency of disasters occurring. 25 persons were selected randomly in each district. So far the early warning messages had been sent targeting only the key persons. Therefore, the overall purpose of this research is to find out how this method can be expanded, to send messages to the community as a whole. During the research it could be understood that people disbelieve of cause about early warning SMS News System, and these systems had not reached the society effectively
