Assessing nutrient flows in septic tanks by eliciting expert judgement
Montangero, Agnes
"Simple models based on the physical and biochemical processes occurring in septic tanks, pit and urine diversion latrines were developed to determine the nutrient flows in these systems. Nitrogen and phosphorus separation in different output materials from these on-site sanitation installations were thus determined. Moreover, nutrient separation in septic tanks was also assessed through literature values and by eliciting expert judgement. Use of formal expert elicitation technique proved to be effective, particularly in the context of developing countries where data is often scarce but expert judgement readily available. In Vietnam, only 5–14% and 11–27% of the nitrogen and phosphorus input, respectively, are removed from septic tanks with the faecal sludge. The remaining fraction leaves the tank via the liquid effluent. Unlike septic tanks, urine diversion latrines allow to immobilise most of the nutrients either in form of stored urine or dehydrated faecal matter. These latrines thus contribute to reducing the nutrient load in the environment and lowering consumption of energy and non-renewable resources for fertiliser production."

How remote are Vietnam's ethnic minorities? An analysis of spatial patterns of poverty and inequality.
Epprecht, Michael
This paper investigates whether physical accessibility or ethnicity is a stronger determinant of poverty in Vietnam. Spatially disaggregated welfare indexes for population subgroups show that overall inequality is shaped by an urban–rural welfare divide, closely followed in importance by sharp welfare differences between ethnic groups. Accessibility to urban areas is a weaker determinant of poverty.The findings have important implications for the targeting of rural development investments. Addressing the factors isolating ethnic minorities from the mainstream economy is likely to be a more useful strategy in reducing rural poverty and inequality than simple geographic targeting.

Material flow analysis as a tool for environmental sanitation planning.
Montangero, Agnes
This paper illustrates how the method of Material Flow Analysis (MFA) can be applied to assess measures aiming at optimizing nitrogen recovery through improved excreta management in Viet Tri, Vietnam. The purpose of this paper is to discuss how the application of MFA could be rendered more affordable for planners and decision-makers in developing countries confronted with poor data availability and quality.

Where Are the Poor and Where Are the Trees?
Müller, Daniel
"This paper highlights the spatial linkages of forest quality with poverty incidence and poverty density in Vietnam. Most of the Vietnamese poor live in densely populated river deltas and cities while remote upland areas have the highest poverty incidences, gaps, and severities. Forests of high local and global value are located in areas where relatively few poor people live, but where the incidence, gap, and severity of poverty are strongest, and where the livelihood strategies are based on agricultural and forest activities. Analysis was conducted combining country-wide spatial data on commune-level poverty estimates and the geographic distribution of forest quality. The results suggest the usefulness of targeting investments in remote areas that combine poverty reduction and environmental sustainability."

Patterns of Land Cover Change in the Lower Mekong Basin
Heinimann, Andreas
PhD Thesis, University of Bern, Switzerland "The present study seeks to generate a comparable information and knowledge base about land cover change on a mesoscale level for the entire Lower Mekong Basin. Such information is crucial to both informed decision making and the transboundary negotiations on the use and protection of the shared natural resources in regional bodies such as the Mekong River Commission. It may form the basis for achieving a common understanding regarding resource management in the Basin despite diverging national interests.

Metropolization and the Ecological Crisis
Wust, Sebastian
"This paper describes two experiences with community-led upgrading programmes in precarious settlements in Ho Chi Minh City and discusses how and why these are more effective and appropriate than the city’s "redevelopment" and relocation programmes. Although rapid economic growth has meant improved material conditions for much of the city’s population, it has also had a negative impact on the environment and on the poorer groups whose living conditions are deteriorating, especially in the precarious settlements on vacant lots, along canals and on the city outskirts. The city has plentiful water, but large sections of the population are not reached by piped water and sewers. Although relocation programmes are better managed here than in most cities, many who are relocated suffer a drop in income, a steep rise in housing costs and a disruption to their social networks. The paper ends with some reflections on the changes needed in government attitudes towards citizens."
