Protected areas play a crucial role in the conservation and management of wildlife, but land use and land cover change (LULCC) threatens the status of protected areas. Sri Lanka has a history of severe human–elephant conflict (HEC). In the last 15 years, Sri Lanka has recorded the highest mortality of elephants and the second-highest human casualti...

Human–elephant conflict (HEC) is a key environmental issue in number of Asian countries, including Sri Lanka. Incidents of HEC have significantly increased in Sri Lanka between 1991 and 2018, with 1734 human deaths reported in this period (281% increase), 4837 elephant deaths (1172% increase), 1053 human injuries (140% increase) and more than 23,00...

Land use and land cover change (LULCC) are dynamic over time and space due to human and biophysical factors. Accurate and up-to-date LULCC information is a mandatory part of environmental change analysis and natural resource management. In Sri Lanka, there is a significant temporal gap in the existing LULCC information due to the civil war that too...

River basin is the entire land area supplying its water into a river and thus river network and its drainage area which can be explained through morphological characteristics control the hydrological processes occurring within the river basin. Hence, the present study attempted to assess the morphological characteristics of Maduru Oya river basin t...

Land use and land cover change (LULCC) is intrinsically dynamic over time and space due to human and biophysical factors. Accurate and up-to-date land use/cover information is a mandatory requirement in environmental change analysis and natural resource management. Satellite earth observation is being increasingly applied in LULCC detection across...

Kandyan Home gardens (KHGs) are multi-species traditional agro-forestry system which provides many services while conserving biodiversity. Land Use (LU) / Land Cover (LC) changes in the area adversely affect on biodiversity in KHGs. The LU/ LC changes in Kandy District were analyzed using Remote Sensing (RS) and GIS techniques. LU/ LC Change maps f...

Mangrove ecosystems dominate the coastal wetlands along the North West Coast of Sri Lanka and they are among some of the most threatened and vulnerable ecosystems. Information on the distribution pattern and extent of such valuable coastal resources is a main requirement for managing and conserving them. The study was conducted to assess the mangro...

ABSTRACT: This paper discusses the application of Geographic Information System in identifying potential areas for aquaculture in Badulla district. Aquaculture is farming aquatic organisms including fish, mollusks, crustaceans and aquatic plants. There is a potential to develop aquaculture practices in Badulla district. Selection of potential site...

Seagrasses perform multiple functions for the marine environment. They not only provide beneficial ecological services to the environment, but also for coastal human population. However, increasing anthropogenic activities in coastal environment has leaded this valuable resource to face depletion. The continuous loss of seagrass will lead to advers...

Elephant intrusion in human settlement is one of the key issues in Sri Lanka which has given devastating impact on humans and the elephants and it has been continued for several decades. Elephants intrude to human settled areas mainly because of the scarcity of food and the water at the protected areas. The protected areas in Sri Lanka scatted thro...

The poster displays the analysis of the human elephant conflict in Sri Lanka in relation to the rainfall seasons.

Elephant intrusion in human settlement is a top issue which has the devastating impact for humans and the elephants in Sri Lanka continue for several years, but the issue of elephant intrusion has never addressed in a national scale to see the patterns and the trends on it. And also there is no good data base available in the country about the conf...
