The efficiency of the solid waste management process in Kirikiththamulla Grama Niladhari Division
(Department of Geography, University of Kelaniya, Sri Lanka., 2020) Mandira, M.A.T.; Amarasinghe, A.G.
Inefficient disposal of waste can be ascertained as a social as well as a significant environmental problem. It has also resulted in the creation of varietal waste management issues. Waste management has become a problem both in urban and rural areas in Sri Lanka. Participatory observations, interviews, and questionnaires were employed in gathering primary data for this study. A sample of 50 families in Kirikiththammulla GND was selected and a set questionnaire was used to collect data. Secondary data was obtained through the use of company data, reports, statistics, prior researches in the same field, newspapers and journal articles. Ignorance and carelessness of people, inadequate facilities for waste recycling, attitudes of people, inadequate knowledge in relation to waste management, the rapid increase in waste products, and the absence of an effective waste management mechanisms are the main factors resulting in the inefficient disposal of waste in the study area. To minimize this situation educating the rural communities, improve waste management facilities introduce waste recycling practices and educate the community about the social and environmental impact of waste disposal through formal disposal can be regarded as solutions to the Waste Management Industry.
Environmental issues associated with inappropriate land usepattern: The case on Bahirava Kanda Grama Niladhari Division in Kandy District
(Department of Geography, University of Kelaniya, Sri Lanka., 2020) Attanayake, A.M.P.S; Amarasinghe, A.G.
Inappropriate land use patterns in Sri Lanka has created many environmental problems. Population growth, urbanization, rising land prices, and intensive agricultural activities are the main reasons that cause inappropriate land use patterns. The Bahirava Kanda Grama Niladhari Division which belongs to the Gangawata Korale Divisional Secretariat of the Kandy District is a hilly area close to the Kandy municipality. As the study area close to Kandy city, for the land. As such, the land is severely misused. The main objective of this study is to study the environmental problems associated with the inappropriate land use pattern in the Bahirakanda GND area. To achieve the target, 35 households were selected through the simple random sampling method from the total number of families in the study area. Both primary data and secondary data were used in this study. Questionnaire methods, interviews, and observations are used to collect primary data. In the secondary data review, information was collected under books, journals, reports, maps, and office data. Quantitative data analysis and descriptive data analysis were used in data analysis and Geographic Information System was used to create maps. MS Excel is also used to create tables, charts, etc. for data analysis. This analysis revealed that the slopes of the study area are mostly used for the informal house constructions. In Bahirava kanda, the number of informal house constructions with risk is 38%. As a result, problems of landslide risk, maximum soil erosion, forest degradation, groundwater pollution, and sedimentation of waterways were identified within the area. In order to mitigate these problems, proposals for mapping of landslide hazard areas and public awareness, Prevention of fragmentation of lands, growing vegetation on the surface of the land, controlling of drainage systems parallel to the slope gradient, recommendations of NBRO for construction can be proposed.
Impacts of human activities on soil erosion: A case study in Wewere GND, in Minipe DSD
(Department of Geography, University of Kelaniya, Sri Lanka., 2020) Danasekara, D.R.A.K.; Amarasinghe, A.G.
Human activities influence heavily on soil erosion in Sri Lanka. Soil erosion in rural areas is high, due to various human activities. Wewere GND is selected for this study as there was high consumption of land for agriculture in Kandy district. The main objective of this study is to identify the human activities which accelerate the natural process of soil erosion and provide the solution to conserve soil erosion. The methodology of the research was a mixedmethod under the holistic approach. Hence to achieve the target, Wewere GND was divided into 7 land units according to the types of human activities in the area and obtained 1 kg of soil from each land unit through the simple random sampling method. Further, experiments were conducted in the laboratory and the final results were analyzed. The results were represented with maps using Arc GIS and charts, graphs, tables using MS Excel. 100g of soil from each soil samples were taken, 2mm sieved each sample and obtained 2 fractions to determine their particle sizes. The fraction which is more than 2mm (+2mm) is selected as the results of each sample. Sub forest represented 4.82 %, crop cultivation represented 41.36% of soil particles(+2mm). The result substantiated high soil erosion was represented in crop cultivation (41.36%) due to the human activity and less was represented in sub forest (4.82 %). The mismanagement of land, proper soil conservation measures are not being adopted to the villagers, improper land use and less knowledge are the causes of accelerated soil erosion in Wewere GND. Vegetative methods, structural methods, management practices, and awareness programs should be executed to the conservation of soil erosion in the research area. The management of agricultural systems must be carried on the sustainable approach and related authorities should pay attention to minimize soil erosion.
A Study eco-friendly agricultural and practices for Green Economy: Based on Dompe Divisional Secretariat
(Department of Geography, University of Kelaniya, Sri Lanka., 2020) Samarasinghe, S.A.C.S; Amarasinghe, A.G.
The conference of RIO+20 conference held in 1992 in Brazil to lead the world population for Eco-friendly programmer under the topic of “ Do We Include to a Green Economy ” The main purpose of this conference was to emphasis on how to gain to the contribution of world population for the green economy. Therefore, Sri Lanka is an agricultural based country. The main reason for that is Sri Lanka has the optimum physical factors that are beneficial for agriculture. Sri Lanka is also moving towards a trend of eco-friendly agriculture. The process of developing the economy which is a concept of the “Five-Fold Process” implemented by the previous government has been given priority. Thus today is trying to capture the market for the massive demand internationally for eco-products via eco-friendly organic farming and it has been contributed to ensuring the food sovereignty and safety of the country. The main objectives of this study were to the identification of the ecofriendly organic farming and the contribution of eco-friendly agriculture for the green economy in the competitive economy. Dompe divisional secretariat which is a backward development area in the core zone was selected as my study area. Primary Secondary & tertiary data have been used for investigating the eco-friendly agriculture. The sample of 50 family units was selected under the simple random sample. Linear regression analysis was used to analyze the data. Via this investigating agriculture could be identified as the main economic activity of the 62% of the employees in Dompe Divisional secretariat. Form them about 12% of the employees aware of the concept of a green economy. About 82% of the employees have a sound knowledge regarding eco-friendly farming. The contribution of eco-friendly agriculture to the green economy is about 3%. The economy can be tuned up by capturing the market for the international massive demand for eco-agriculture products. Further, the environment sustainability can also be ensured.
