Taschenbuch. Zustand: Neu. Neuware - Academic Paper from the year 2021 in the subject Environmental Sciences, grade: 100%, , language: English, abstract: The diversity of ants in conventional and organic farms has not been investigated in Tanzania, therefore, the study aims at investigating that and provides knowledge for ants c…onservation. Machare Coffee Estate is among unique plantations in which both conventional and organic farming of coffee are performed. The study contributes to the existing body of knowledge on the influence of these farming practices on ants¿ diversity. Knowledge about ants diversity is useful for the conservation of other species which associate with ants in the ecological chain. Therefore from such a gap in knowledge, this study intends to compare the diversity of ants in organic and conventional farms. Moreover, the findings from this study will aid in biodiversity management and conservation in the area in particular. Ants play a vital-ecological role as they influence soil movement, nutrient cycling and water availability in their habitat. Habitat destruction and the use of Agrochemicals are regarded as among the factors that affect the diversity of ants. Machare Coffee Estate is one of the farms which practice both organic and conventional farming. To reveal whether there is a difference in diversity between these two practices this study was conducted at Machare Coffee Estate for three weeks. The study used four transects of 80 m with four quadrants of 10x10 m within it, where 6 pitfall traps with an inter pitfall distance of 3 m were laid down per quadrant on both sites. A total number of 96 pitfall traps were used per site. A total of 2381 ants from five subfamilies were collected. Ant¿s diversity was analyzed by the Shannon Wiener index and a t-test was used to test the hypothesis. Keywords; Ants, diversity, conventional farming, organic farming.

Taschenbuch. Zustand: Neu. Neuware - Academic Paper from the year 2021 in the subject Environmental Sciences, , language: English, abstract: The research will offer information on bees and the commencement of future actions on conservation of bees in Tanzania and the world at large. In order to provide good pollination service a…t high rate, Bee needs a favorable environment and or area that is free from agricultural products such as pesticides, fertilizers also free from diseases and trampling which will provide a pollination service that is effective. In addition the environment should not be overly cost for bee diversity. Increase in human population has led to the high demand for food; the high demand for food by human has led to the ongoing increase in farm size with specialization leading to the reduction of natural vegetation areas for food production. If the agricultural areas will continue to be treated with pesticides and fertilizers, farmers will be wasting their time because the bee diversity will keep on declining and later on the pollination service will be poorly performed that will result to poor productivity of crops. Also bees suffering can lead to a total disappearance of bees hence lack pollination services completely. Keywords: Agriculture, Diversity, Biodiversity, pollinators, Intensive.

Taschenbuch. Zustand: Neu. Neuware - Academic Paper from the year 2021 in the subject Geography / Earth Science - Regional Geography, grade: 100%, , language: English, abstract: This research aimed at analysing and quantifying urban growth pattern of Urban-West in Zanzibar using Remote Sensing, GIS and Spatial Metrics. To achiev…e this goal various data were used such as Landsat images, Sentinel 2A image and Building data have been utilized. Urbanization is a phenomenon that is of major concern in both developing and developed countries. According to the census record between 1988 and 2002 there was a near-doubling of the urbanized population in Urban-West of region Zanzibar Island and continued high growth since 2002 are unprecedented in intensity, scope and impacts on the lands, particular in Urban-West. Such rapid urbanization of West district has meant that the city has doubled in areal extent. Currently there is lack of timely and quantitative information of the urban growth and its long-term impacts, thus planners haven¿t been able to assess and analyse consistently growth of Urban-West in Zanzibar. Keywords: GIS, Land cover, Remote sensing, spatial, Urban growth.
