Quaternary Organic Deposit from Newton Creek Valley,Western Tasmania

Pollen and macrofossils from an organic deposit probably 44 ka BP in age record subalpine heath with abundant local Athrotaxis cupressoides. This was succeeded by subalpine heath that included Casuarina, Phyllocladus and Eucalyptus. The pollen/vegetation assemblages are comparable with present subalpine vegetation located between 850–1050 m, though the site is at 550 m and potentially below the limit of temperate rainforest (620 m). It is inferred that the vegetation altered from upper to lower subalpine heath and that the climate became warmer and wetter. The mean temperature is estimated to have been at least 3.2°C to 1.7°C colder than today. The trend of vegetation and climate change compares closely with Late Glacial changes but does not compare with changes recorded from sites of Middle Last Glacial age in the West Coast Ranges. A radiocarbon date of 34 ka BP and a trend towards warming suggests that the deposit may represent the onset of an interstadial during the Early Last Glacial Stage.     

Local Knowledge and Economic Realities Affecting Soil Erosion in the Rach Rat Catchment,Vietnam

Several parts of Binh Phuóc Province, southern Vietnam, suffer from degraded soils and vegetation as a result of both natural erosion of weak mud rocks and sandstones and intensive human activity, especially through land clearing for agriculture on unstable slopes, deforestation, and abandonment of poor farmland. The underlying cause of this land degradation has been the farming habits of migrants of varying ethnic groups who have settled in the area since 1980. The indigenous farming knowledge of these people and the role of that knowledge in soil erosion were examined by a series of household surveys. They enabled farming practices to be related to ground cover established from a 2002 Landsat 7 ETM (Enhanced Thematic Mapper), and erosion data from a series of erosion bridge measurements. A GIS (Geographical Information System) approach was piloted as a means of identifying areas vulnerable to erosion. This could then be combined with the understanding of farming practices to reveal the relative roles of farmer behaviour, crop cover, and slope and soil characteristics in the erosion process. Land use, local people's knowledge and economic realities are the main factors, as well as natural conditions, that drive this land degradation.     

Evaluating Ethnopedological Knowledge Systems for Classifying Soil Quality. A Case Study in Bo Hamlet with Muong People of Northern Vietnam

Ethnopedological knowledge is incorporated in a case study for sustainable land management of mountain karst areas in Vietnam. The research is based on a multidisciplinary approach, including participation of local inhabitants for identifying and classifying local indicators of soil quality, next to scientifically sound approaches to soil quality assessment based on analytical soil data and a statistical treatment of the results. The case study focuses on Bo hamlet, located in the Ngo Luong commune of the Tan Lac district, Hoa Binh province. The participatory approach reveals that local people of the Muong ethnic group distinguish seven land use types and six soil types. They also identified nine local indicators of soil quality: presence of earthworms; crop productivity; topsoil colour; presence of a humus layer; soil surface compaction; erosion; slope gradient; surface water, and soil moisture status. Based on this indigenous knowledge, 19 soil samples from nine soil profiles in Bo hamlet were analysed for fertility indicators. Laboratory results confirmed the validity of indigenous knowledge for identifying and classifying local indicators of soil fertility, compared to scientific standards of soil quality.     

Coastal Livelihood Transitions: Socio‐Economic Consequences of Changing Mangrove Forest Management and Land Allocation in a Commune of Central Vietnam

This paper reviews the evolution of land use and mangrove forest management in a coastal commune in Central Vietnam from its early period of environmentally sound management under a common property regime, through State and cooperative management, to individual household allocation under the economic reforms of the 1990s. It analyses in particular the introduction of shrimp culture and its environmental and socioeconomic consequences. The case study demonstrates that, while opening up many economic opportunities, Vietnam's economic reforms have had uneven impacts on income inequality. Like many cases in Asia and Latin America, the disruption of common property resources – through the introduction of aquaculture as a livelihood opportunity and producer of an export crop – leaves farmers indebted and natural resources polluted. But, ironically, it was the financially better‐off aquaculture farmers, who had more capacity for risk‐taking and investing, who ended up most indebted, in comparison with poorer farmers who had already sold their ponds. The latter were less integrated into the market economy and relied more on marine product collection. This paper suggests that attention to local contexts and histories can contribute to a better understanding of the causes and consequences of environment‐poverty interfaces.     

Palaeoepidemiological Patterns of Trauma in a Medieval Nubian Skeletal Population

Evidence of trauma was investigated in a well-preserved skeletal sample from the Medieval Sudanese Nubian site of Kulubnarti. The skeletal materials derive from two temporally over-lapping Christian cemeteries, dating from the sixth to circa the sixteenth century. The available sample consisted of the skeletons of 146 adults which were investigated for fractures of the long bones, crania and the hands and feet, as well as for dislocations and muscle pulls. Results showed a high incidence of long bone fractures, seen especially in the forearm, and involving 33.5 per cent of individuals. Many of these lesions indicated quite severe injury, and an unusually high number of affected individuals (27 per cent) showed multiple long bone involvement. Conversely, only one possible cranial fracture was apparent. Fractures were also found in 13 hand and seven foot elements. In addition, one hip dislocation and evidence of pulled tendons in 11 individuals were also observed. Compared to other similarly controlled samples, the Kulubnarti population stands out for its high prevalence of healed fractures, the high proportion of multiple involvement and the severity of numerous lesions. The forbiddingly harsh and uneven terrain of this region of Nubia was most likely a major influence on the unusually high prevalence and pattern of traumatic lesions in this group. © 1997 by John Wiley & Sons, Ltd.
