This paper summarizes the result of vegetation cover changes in Mato Grosso State in Amazonia, and changes on hydrological aspects of that region. The study area is the main soybean plantation area of Brazil along the Highway BR 163, in the Rio Verde Drainage. Using multi-temporal imageries of Landsat TM of the same area, alteration of vegetation cover was analyzed, performing unsupervised clas...
OBJECTIVES The aims of this study were to assess the regional differences in domestic violence among pregnant women in the capital district and in the tea plantation sector of Sri Lanka, to explore potential contributory factors and to assess whether healthcare workers addressed domestic violence and disclosure among survivors. DESIGN A cross-sectional study was carried out using interviewer-...
This experiment was done to determine the effectd of growth stage on chemical composition and processing by NaOH and CaOH2 on ruminally degradability of Haloxylon sp. pasture plant in seeding stage. The enough amount of Haloxylon in 3 vegetation stages was prepared from Amari SarChah in May and October and December of 2010. The chemical composition of Haloxylon sp. was determined in three stage...
The objectives of this study were to evaluate the influence of propagules source and the implication of tree size class on the spatial pattern of Xylopia brasiliensis Spreng. individuals growing under the canopy of an experimental plantation of eucalyptus. To this end, all individuals of Xylopia brasiliensis with diameter at soil height (dsh) > 1 cm were mapped in the understory of a 3.16 ha Eu...
BACKGROUND Soil-transmitted helminths (STHs) and Plasmodium falciparum infections remain public health problems in Cameroon. A cross-sectional study was carried out in the Mount Cameroon area to determine the prevalence and intensity of STHs and P. falciparum infections in individuals living in different agroecosystems; to assess the influence of these infections on haematological parameters; a...
The aim of this study was to investigate vegetation composition in broadleaved and conifers plantations in 220 ha of Loblloly pine (Pinus taeda), alder (Alnus glutinosa( and poplar (Popolus deltoides) hardwood plantations and its comparison with natural forests in Bibiyanlu protected forest park, Astara. A total of 60 sampling plots of 1000 m2 were taken using randomly-systematic method with1...
Traditionally, plantation sector in India has been regarded as a source of foreign exchange. Hence the system of innovation and production evolved over the years mainly at the instance of the state has been geared to enhance its international competitiveness. Though the role of plantation sector in the export basket of India declined over the years, the paper argues that the present role of pla...
This paper examines changes in carbon (C) pools associated with land-use, synthesizing data from two experiments dealing with different aspects of tree plantation establishment in Central Panamá. First, we analysed soil profiles in a grazed pasture and an adjacent 5-year-old teak (Tectona grandis) plantation. There were small differences in soil C mass in the top 10 cm of the pasture and the pl...
Four different forest restoration modes (Acacia mangium plantation, mixed-native species plantation, conifer plantation and Eucalyptus plantation) were evaluated using Energy System Theory and the emergy synthesis method. In addition, the eco-exergies of the four forest restoration modes were calculated, and combined with emergy and empower density to explore the restoration and selforganizatio...
This paper examines idiosyncrasies of tea plantation culture and politics in relation to Sri Lankan national and popular cultural typologies, with special reference to female tea plantation workers. Tea production in Sri Lanka is heavily based on manual labour, and it is the largest industry that provides accommodation for employees and their families. In this paper, it is argued that politico-...
