People, parks and rangelands: an analysis of three-dimensional woody vegetation structure in a semi-arid savanna

Fisher, Jolene Tichauer 06 January 2014 (has links)
A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy 29 July 2013 in Johannesburg, South Africa / Effective management of protected areas and communal rangelands, which are often juxtaposed in developing countries, is essential to prevent biodiversity decline and ensure a sustainable resource base for rural communities. However, in human-modified landscapes, there are complex interactions between factors that determine woody vegetation structural patterns. While the underlying biophysical template continues to influence vegetation patterns in a predictable manner; the intensity and type of disturbances that are the result of resource extraction, fire and herbivory can have an overriding impact. In order to effectively conserve biodiversity and plan for sustainable resource use, an understanding of land-use and land management is required. A case study of adjacent protected areas (Kruger National Park (KNP), a national protected area and Sabi Sand Wildtuin (SSW), a private game reserve) and communal rangelands (in Bushbuckridge Municipality (BBR) with varying intensities of use) in north-eastern South African savannas was used to study the spatio-temporal patterns of three-dimensional (3D) woody vegetation structure as a result of natural resource management and abiotic drivers. The aim of this PhD thesis is to advance our understanding of the effects of management of natural resources on spatio-temporal patterns of 3D woody vegetation structure across land uses in a heterogeneous semi-arid savanna system. Vegetation structure was measured using small-footprint, discrete-return LiDAR (Light Detection and Ranging) collected by the CAO (Carnegie Airborne Observatory) Alpha System over 35 000 ha across the study area. 3D woody vegetation structure was compared both within land uses (KNP versus northern SSW, and within BBR) and between land-uses (southern SSW versus BBR) to address two objectives, namely 1. Can LiDAR be used as a monitoring tool for management of woody vegetation structure and biodiversity in semi-arid savannas and 2. What is the impact of land use and the corresponding management of resources on woody vegetation structure in semi-arid savannas? Different land-use legacy timelines and current management objectives at sites in KNP and northern SSW has resulted in an average of 2.5 times higher vegetation density <3 m and >6 m in SSW. These differences in vegetation structure are exacerbated by current management practices, with implications for faunal biodiversity conservation across all scales. Not all reserves are equal in their ability to conserve biodiversity and such knowledge should be considered in conservation planning and management. In the communal rangelands, intense fuelwood harvesting has resulted in coppiced trees <3 m in height, and the only trees >5 m are preserved for cultural reasons, producing similar vegetation patterns to Sabi Sand Wildtuin. Disturbance (extraction and grazing) gradients occur with distance from settlements, with utilization intensity affecting vegetation cover within the size class distributions, but not the shape. Gradients diminish under heavier utilization resulting in a more structurally homogenous landscape, which may be used as an early warning sign of woodland degradation. The increase in >3 m tall trees was twice as high in low intensity use CRs adjacent to SSW compared to those in southern SSW from 2008 to 2010, indicating the impacts of treefall from megaherbivores and fire management reducing plant recruitment/regeneration in the protected area. Knowledge from investigation of socio-ecological drivers in the two land-uses were used to construct an ecologically relevant 3D woody vegetation structural classification which can be used by land managers to plan for sustainable resource use and effective conservation of biodiversity. The management of natural resources, including direct use of fuelwood and the management of herbivory and fire affects woody structural dynamics; however, a lack of knowledge exists around the social and ecological context of natural resource management. The use of remote sensing, the knowledge of savanna ecology and an understanding of community-based natural resource management is integrated in this thesis to contribute to the context specific understanding of drivers of woody vegetation structure in two socio-ecological systems (protected areas and communal rangelands) which can be used in sustainable natural resource management plans.

Capital financeiro e empreendedorismo: considerações sobre o sujeito contemporâneo em Match Point, de Woody Allen / Financial capital and entrepreneurship: considerations on contemporary subject in Match Point, by Woody Allen

Anjos, Ana Paula Bianconcini 26 August 2010 (has links)
O objetivo desta dissertação é compreender a configuração do sujeito contemporâneo no filme Match Point (2005), de Woody Allen. Na carreira de Allen, este filme representa o momento de uma espécie de exílio. Por problemas de financiamento nos Estados Unidos, o diretor nova-iorquino vai para a Europa. No centro do capitalismo financeiro, simbolizado pelo prédio de negócios, um irlandês alia-se à elite britânica. O protagonista reúne os valores sociais do empreendedor em um momento histórico anterior à derrocada financeira em 2008. / The aim of this dissertation is to understand the role of the contemporary subject in the film Match Point (2005), by Woody Allen. In Allens career, this film represents the moment of a sort of exile. Due to funding problems in the United States, the New-Yorker director goes to Europe. In the center of financial capitalism, an Irishman joins the British elite. The protagonist combines the social values of entrepreneurship in a historical moment that precedes the global financial crisis in 2008.

När metropoliten flög över Atlanten och blev kosmopolit : Woody Allens skildring av europeiska storstäder / When the metropolitan flew over the ocean and became a cosmopolitan : Woody Allens depiction of European citys

Berg, Andrea January 2012 (has links)
Min uppsats handlar om Woody Allens skildring av staden. Det är inte New York denna uppsats handlar om, utan om de europeiska storstäderna London, Barcelona, Paris och Rom. I dessa städer har Woody Allen spelat in fem filmer. Dessa filmer är Match Point (2006), Scoop (2007), Vicky Cristina Barcelona (2008), Midnight in Paris (2011) och To Rome With Love (2012). Det ryktas även att hans nästa filmprojekt kommer att utspela sig i en europeisk storstad.  Varje film visar utvalda sidor av respektive stad. Allen väljer att visa utvalda sidor av staden, som utgör vilket uttryck staden ger till filmens berättande. Därav får åskådaren motsvarande intryck av hur Woody Allen ser på staden. Exempelvis handlar dessa val om hur filmen kartlägger staden, hur karaktären förändrar sina åsikter när den befinner sig i staden, och hur moraliska imperativ i storstadsturism framkommer genom filmen. Allen har nämligen använt sig både av ikoniska byggnader som indikerar respektive stad, som Eiffeltornet för Paris, men samtidigt visat mindre kända miljöer av respektive stad. Han har med andra ord varvat klichéklassade stadsvyer med mer personliga vyer av andra, mindre kända, delar av respektive stad.                       Trots att de första filmerna Match Point (2006) och Scoop (2007), som utspelas i London, inte nödvändigtvis handlar om turism, handlar de ändå om en amerikanska som besöker en icke-amerikansk stad, på andra sidan Atlanten. Samtliga filmer jag undersöker i denna uppsats handlar om olika typer av amerikaner som besöker europeiska städer. På olika sätt påverkas nämligen dessa amerikaner av respektive stad. Dessa sätt jämförs med hur med 1920-talets stadssymfonier och 1950-talets ”runaway romances”. I urvalda filmer från 1950-talet fungerade nämligen Europa som en tillflyktsort för amerikaner som ville hitta sitt jag och inleda affärer. Jag har kommit fram till att identitetssökande och otrohet i Woody Allens filmer är mer legitimerade än det var på 1950-talet. Dessutom liknar Allens Parisfilm och Romfilm stadssymfonier från 1920-talet. Dessa filmtrender från 1900-talets första hälft hänger då ihop med Allens filmer från 2000-talet. Detta förklaras i en djupgående närläsning av Woody Allens sätt att skildra europeiska städer. I denna analys dissekeras turistbegreppet, hur den skiljer sig från resenärsbegreppet och hur tiden har förändrat hur amerikanska turisterna förhåller sig till respektive stad och invånarna i respektive stad.
