Monday, March 17th, 2008This paper examines the impact of irrigation development on livelihoods of rural communities based on a study implemented in an irrigation development project in southern Sri Lanka. Though irrigation development is one main strategy for socioeconomic development and poverty eradication in many developing countries in the world, it is perceived to have both positive and […]
Land Fragmentation for building residences and Environmental Degradation in Sri Lanka (with reference to Gampaha District)
Monday, March 17th, 2008Many Environmental problems including elimination of tropical forests, desertification, and reduction in biodiversity, are most clearly evident in the Third World. While rapid population growth is often considered an important factor in this environmental degradation, solid empirical evi dence on its role is almost nonexistent. Understanding the effects of population on the environment requires careful […]
Ethnobotany of Upper Hantana Catchment Area
Monday, March 17th, 2008products form the backbone of subsistence and local economies in rural communities in the world. In Sri Lanka too forest products are an integral part of the rural economy. This study investigated the ethnobotanical importance of four planted woodlands [(i) Alstonia (ALW), (ii) Paraserianthes (PAW), (iii) mixed species (MSW) and (iv) Pinus (PIW)] and an […]
Potentially mineralizable carbon in soils under defferent land management
Monday, March 17th, 2008Soil organic matter pools provide insight into the potential stabilization or degradation of the soil resource by various long-term land management systems. Potentially mineralizable carbon (PMC) in soil is a measure of easily decomposable carbon and considered an important pool of soil organic matter. PMC was measured in soil samples taken from six different land […]
Restoration of Tsunami affected Landscape and Plant Diversity in Dharmapala Park in Galle
Monday, March 17th, 2008Approximately 6 ha. of Dharmapala Park in Galle City has traditionally been maintained as a recreation area for children and adults. Owing to significantly poor horticultural attention and maintenance for many decades and the Tsunami hit, most of the lower level trees, shrubs and landscape designs as well as a few buildings and structures have […]
Spatial and temporal variabilities of groundwater characteristic distri bution in the Nilwala River Basin
Monday, March 17th, 2008The study was conducted in Southern Sri Lanka which is bound by longitudes 80.50 E and 80.59 E and latitude 5.59 N and 6.07 N in the Right Bank of Nilwala river Basin. This study aimed to identify corrective and behavior of the groundwater quality changers, present groundwater levels fluctuations with precipitation and groundwa ter […]
Tree Species Preferences on Urban Area’s Residential Plots of Morogoro and Kinondoni Municipalities, Tanzania
Monday, March 17th, 2008The study was conducted in Morogoro and Kinondoni municipalities to identify tree species planted in urban area on residential plots and investigate reasons compelled urban dwellers to plant trees on their homesteads. The study was a cross-sectional and data were collected from 120 plots. Structured questionnaires’ survey, focused group discussion coupled with researcher’s observations was […]
The dynamics of shifting cultivation captured in an extended Constraint Cellular Automata land use model
Monday, March 17th, 2008The Constraint Cellular Automata (CCA) land use model has found many applications in research and planning practices. A CCA model (the RUHUNUPURA model) was set up for the Ruhunupura area of Sri Lanka using the METRONAMICA® software. Preliminary model simulations revealed that the model is not capable of capturing the proper dynamics of the ‘chena’ […]
Consequences of climate change impacts on Southwest Monsoon Rains and natural resources management in Sri Lanka
Monday, March 17th, 2008Anthropogenically induced climate change is expected to influence rainfall, temperature and other associated climatic factors. In this study climate change datasets for Sri Lanka were derived from the UK Hadley Centre for Climate Prediction and Research model (HadCM3) for selected IPCC, Special Report on Emission Scenarios (SRES) scenarios A2 (Differentiated World-Regional Economical aspects) and B2 […]
THREATS TO NATURAL HABITATS AND THREATENED PLANT SPECIES IN THE CONTEXT OF COMMUNITY PERCEPTION: AN ETHNOECOLOGICAL PERSPECTIVE
Monday, March 17th, 2008This is basically an ethnographic study with ecological perspective in order to promote community participa tion in conservation and management of natural resources. For this study forty three (43) village localities from five areas with different geo-ecological and socio-cultural backgrounds were selected in Medicinal Plants Conservation Areas (MPCAs). All the data collected were compared with […]
