IMPACTS OF KALU RIVER ESTUARY CHANGES ON NEARBY COASTAL ZONES FROM 2017 TO 2020: AN INTEGRATED ANALYSIS USING GIS AND DSAS Fonseka, Piumi; Karunarathne, Ananda Y. Coastal environments are dynamic and sensitive systems subject to various natural and anthropogenic influences. This study investigates landform changes near the Kalu River estuary in Sri Lanka from 2017 to 2020, using Geographic Information System and Digital Shoreline Analysis System. Multiple shoreline change analysis methods, including Linear Regression Rate (LRR), Transect line, Shoreline Change Envelope (SCE), and Net Shoreline Movement (NSM), quantify erosion and accretion patterns have been utilized in the study. Zone 2 experienced significant erosion while accretion was observed in Zone 3(see, figure 10) and 717 Kalutara North. The interconnectedness of estuaries and coastal environments is highlighted, emphasizing the direct impact of estuarine changes on nearby beaches. The study underscores the importance of understanding estuarine dynamics in coastal management and planning. It sheds light on vulnerable areas and offers opportunities for coastal protection and sustainable development. The research contributes valuable insights into coastal system complexities, calling for comprehensive assessments to safeguard coastal communities and environments in the face of ongoing environmental changes. The integrated analysis provides a foundation for targeted strategies to mitigate erosion, enhance coastal resilience, and promote sustainable coastal disaster risk reduction (CDRR) practices in the study area. Ultimately, such comprehensive assessments are crucial for safeguarding the ecological integrity and socio-economic well-being of coastal communities and environments in the face of ongoing environmental changes. *Corresponding author: E-mail address: ananda@geo.cmb.ac.lk

INSELBERG: ADAPTATION TO SURROUNDING ENVIRONMENT AND NEGLECTED AS NATURAL HERITAGE IN SRI LANKA Katupotha, K.N.J. An inselberg is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. It results when a body of rock resistant to erosion, such as granite or gneiss, formed within a body of softer rocks, is exposed by differential erosion and lowering of the surrounding landscape. Inselbergs are isolated formations that rise above a plain, which consists of hard bedrock. If they have a soil cover, then it becomes very sparse. Where the soil is too thin or hard to support tree life in large areas, soil trapped by inselbergs can be dense with trees while the surrounding land contains only short grass. Hollows in the rock surfaces provide catchments for rainwater. They vary in height depending on their development, and they take on different forms, as far as both ground plan and cross section are concerned, according to their genesis and lithology. Microforms caused by weathering can have formed on the rock surfaces. Inselbergs enrich their surroundings with nutrients via drainage, amounts of total nitrogen, nitrate-nitrogen and potassium in rainfall, drainage from bare rock patches and vegetation mats (cover) on an inselberg. Some animals have adapted to use of inselbergs and their surroundings in Sri Lanka, including the elephants, Sri Lankan leopard (Panthera pardus kotiya), bears, and an abundance of bird and reptile life. Floral diversity from tree species to lichens are also highly useful for foods as well as for medicine. In addition to the above, inselbergs can be recognized for the education sector from secondary education to the university level. But, in Sri Lanka, all these sectors have been neglected by educators, planners and policy makers. At all events, inselbergs as natural and national heritages are invaluable resources. *Corresponding author: E-mail address: katupotha48@gmail.com

FACTORS AFFECTING THE EMPLOYMENT OF WOMEN: WITH SPECIAL REFERENCE TO AMPARA DISTRICT Gayanthi, K.T.D.; Jagoda, D.J. People who are employed and actively looking for work but are unable to find it are defined as unemployment. Since the 1960s, a common issue in Sri Lanka has been the lower employment of women in the labour force according to the Central Bank Report. The employment rate of women was 52.6% in the world, 25.2% in South Asia, and 32.8% in Sri Lanka. In 2021, the highest unemployment rate in Sri Lanka was reported in Trincomalee district (17.7%). Most of the surveys have investigated women’s unemployment in Sri Lanka. The main objective of this research is to identify the factors affecting the employment of women in Ampara district. Multi-stage cluster sampling method was used to select a sample of 288 women from the Ampara district, which had the second-lowest employment rate in 2021. Primary data for the study were gathered through online structured questionnaires and face-to-face interviews. To achieve the main objective, binary logistic regression was employed with 25 independent variables using a quantitative approach. It was revealed that age positively affects the employment of women, while the number of income earners and family income negatively affect the employment of women. Finally, it was suggested that above mentioned significant variables can strongly impact the employment of women, so it’s recommended that create new employment opportunities for women and provide training for unskilled workers. The findings of this research are very useful for policymakers to determine possible actions to increase employment. *Corresponding author: E-mail address: dinugayanthi@gmail.com

CONSEQUENCE OF SOCIAL MEANINGS EMBEDDED IN FORESTS IN CONTROLLING MISBEHAVIOR OF ECO-TOURISM STAKEHOLDERS: A CASE STUDY OF MEEMURE VILLAGE IN SRI LANKA Pathmasiri, E.H.G.C. Global warming and global climate change impasses have dramatically become two of the biggest challenges of the current world. The serious consequences of global warming are on the rise throughout the Northern and Southern hemispheres. For instances, prolonged droughts, catastrophic heatwaves, disastrous forest fires, strong cyclones and storms, tornados, torrential rains, mass flooding events, extreme cold waves and winter conditions, accelerated ice caps melting etc. have seriously come to the fore. Efforts are being made to address these issues at different levels and mitigate the negative impacts on the human population and also on the environment. It is essential for governments, stakeholders, INGOs, and environmental organizations to work together to develop and implement effective strategies that minimize the negative impacts of global climate change impasses. On this context, this global review sheds some lights by demonstrating the credible evidences of global warming and global climate change impasses with recent examples. The study employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model to systematically filter and select relevant literature. Following a rigorous process of identification, screening, and inclusion, manuscripts, news articles, and reports published in English were considered for analysis. In line with the study's criteria, inappropriate or unrelated literature was excluded. After the filtering process, a total of 48 literature sources were included in the study, selected from an initial pool of 80 pieces. In accordance with the results, this comprehensive global review illuminates the undeniable evidence of global warming and the critical challenges posed by climate change, supported by recent and pertinent examples. In other words, within the given context, this extensive global review provides valuable insights into the irrefutable proof of global warming and the pressing issues posed by climate change. By examining current and recent examples, the review substantiates the urgency and significance of addressing these global challenges. *Corresponding author: E-mail address: ananda@geo.cmb.ac.lk
