Opis:
The prime objective of this study is to assess the socio-economic impact of wetlands in the study area; the secondary objective is to establish the condition of the wetlands and to propose remedial measures. Primary and secondary data were used for this study. As primary data, we employed direct observation, questionnaire survey and group discussion. As secondary data, we utilized statistical data from Navithanveli DS Division, previous researches and general ecological works. In Navithenveli DS Division, inhabitants are benefitted by wetlands in many ways. Paddy cultivations, vegetable cultivation, small-scale fishing, biodiversity, groundwater recharge, gardening, Tule mat industry and water for domestic usages. Indiscriminate activities of inhabitants, unplanned and improper infrastructure have caused many challenges for the wetlands in the study area. Many remedial measures have been recommended to conserve the wetlands in the study area.

Opis:
The tidal action is one of the most significant forces of the littoral changes. This study mainly focuses on coastal morphodynamics associated hazards which are caused by the natural phenomena. The study area, which is covered about 16 km in length, is rich by coastal resources and has an abundance of natural biodiversity. The objectives of this study (a) to identify the coastal morphodynamics associated hazards by the waves in the study area and (b) to detect coastal morphodynamics using time series data from 1981 to 2015 and to show the intensity of shoreline changes with the aid of Geo Spatial Technology. For this study, Aerial photograph in 1981 and satellite images of 2001 and 2015 used to identify the costal morphodynamics of the study area and they were subjected to the analysis with the aid of GIS 10.5 software. This study is concluded that the coastal morphodynamics associated hazards have been identified heavily in the study area due to the severe wave action.

Opis:
This study under the title of “the environmental challenges of declining mangroves: a study based on Puttalam District in Sri Lanka” was undertaken to attain the primary objective ‘to identify the factors for the declining of the mangroves in the study area’ and the secondary objectives ‘identify the environmental challenges due to the mangroves declining in the study area and to suggest was to control the decline and to provide awareness of this problem among the inhabitants’. Both, primary and secondary data were collected for this study. As primary data, questionnaire survey, direct observation and constructed discussion were used. As secondary data, statistic reports, previous researches, books and magazines were employed. According to the analysis, major environmental challenges were encountered. These included ‘land fragmentation, biodiversity destruction, decreasing endemism in mangrove, loss of herbs and coastal soil erosion’. To overcome these challenges, many recommendations were put forward.
