ItemNo Preview AvailableLand-Based livelihoods(Routledge - Taylor & Francis, 2005)African farmers and pastoralists have been meeting their everyday needs in diverse ways for many centuries. While this process has increasingly been recognized since the late colonial period, a major development since the publication of Lloyd Timberlake’s Africa in Crisis (Timberlake, 1985) has been the emergence of support to ‘livelihood security’ and the incorporation of ‘sustainable rural livelihoods’ in the rationales and thinking of government-led projects and the many international development agencies working in Africa. Researchers too have focused renewed attention on how diverse rural societies enhance their welfare and development options in many corners of the continent.

ItemA survey of modern pollen and vegetation along an altitudinal transect in southern Georgia, Caucasus region(ELSEVIER SCIENCE BV, 2004)This paper describes the pollen representation of vegetation patterns along an altitudinal transect in the South Caucasus region. Surface sediments from eight small- to medium-sized lakes and wetlands were analysed for modern pollen, and the results analysed numerically using detrended correspondence analysis (DCA) and dichotomised ordination (TWINSPAN). Pollen spectra from the semidesert region have a clear palynological signal characterised by an abundance of Chenopodiaceae. Differentiation of oak forest, upper tree-line and subalpine communities is more difficult: all are dominated by arboreal pollen (AP) types. The authors propose a number of indicator pollen types and pollen threshold values that may assist in detecting tree-line variations and deforestation events in Holocene pollen diagrams.

ItemAre the spatial patterns of weeds scale-invariant?( 2004)In previous empirical and modelling studies of rare species and weeds, evidence of fractal behaviour has been found. We propose that weeds in modern agricultural systems may be managed close to critical population dynamic thresholds, below which their rates of increase will be negative and where scale-invariance may be expected as a consequence. We collected detailed spatial data on five contrasting species over a period of three years in a primarily arable field. Counts in 20x20 cm contiguous quadrats, 225,000 in 1998 and 84,375 thereafter, could be re-structured into a wide range of larger quadrat sizes. These were analysed using three methods based on correlation sum, incidence and conditional incidence. We found non-trivial scale invariance for species occurring at low mean densities and where they were strongly aggregated. The fact that the scale-invariance was not found for widespread species occurring at higher densities suggests that the scaling in agricultural weed populations may, indeed, be related to critical phenomena.

ItemThe Eden woodchip scheme and its implications for forest fauna: a political ecology perspective(Royal Zoological Society of New South Wales, 2004)A ‘political ecology’ perspective was used to examine the implications of the export woodchip scheme located near Eden in south east New South Wales (NSW) for the region’s public forests and their fauna. The modern paper industry’s political economy emphasises the importance of a large supply of wood fibre of suitable price and quality for competitive papermaking. The evolution of the Japanese paper industry and the exploitative history of forests in south east NSW interacted to create the opportunity to establish such a supply in Australia for the Japanese papermaker Daishowa Paper Manufacturing Co from 1970. The ‘Harris-Daishowa’ export woodchip scheme at Eden was based on the guaranteed supply of large volumes of pulpwood from the region’s public native forests. Meeting this supply entailed restructuring available forests through clearfell logging over about 40 years. Featuresof the regime used to manage these forests and supply pulpwood were examined within this context, and the consequences of woodchipping for fauna protection are discussed. Fauna populations were being restructured by this regime, which ‘squeezed’ them between priorities for wood production and fire management. In particular, forest-dependent fauna, such as gliders, some possums and koalas, have been detrimentally impacted. Substantial changes to public forest management in south east NSW took almost 30 years to achieve. However, while export woodchipping continues, the ‘political ecology’ of local forest fauna will be influenced by international pulp and paper markets.

Item"En territoire belge et à quarante centimètres de la frontière": an historical and documentary study of the Belgian and Dutch enclaves of Baarle-Hertog and Baarle-Nassau(The School of Anthropology, Geography and Environmental Studies, The University of Melbourne, 2004)Enclaves are defined as a fragment of one country totally surrounded by one other country. Currently, 259 enclaves exist in the world, all in Europe and Asia. Thirty of these enclaves, twenty-two Belgian and eight Dutch, cluster in and around a single village in the southern Netherlands, which is thus divided into the Belgian commune of Baarle-Hertog and the Dutch commune of Baarle-Nassau. The 800-year long history of these enclaves is presented for the first time in English, detailing their origin c.1198, and explaining their survival despite numerous European wars and boundary changes. A description of the situation in the enclaves today is also given, together with the effect of the enclaves on everyday life and administration in the village. A large number of maps and photographs illustrate the paper, including a series of maps depicting every one of the 959 turning points of the boundaries of the 30 enclaves, showing all buildings and properties bisected by this most unusual boundary.
