How remote are Vietnam's ethnic minorities? An analysis of spatial patterns of poverty and inequality.

Michael Epprecht, N. Minot, Daniel Müller, 2009

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.

Frontier Encounters: Indigenous communities and settlers in Asia and Latin America

Danilo Geiger, Marina T. Campos, Christian Erni, Søren Hvalkov, Sabino Padilla, Jr., Devasish Roy, Ranabir Samaddar, 2008

Poverty and the maldistribution of land in core areas of developing countries, together with state schemes for the colonization of unruly peripheries, have forced indigenous peoples and settlers into an uneasy co-existence. On the basis of case study material from various Asian and Latin American countries, Frontier Encounters identifies characteristic patterns of interaction between these groups, explores the dynamics of some of the open conflicts that dot the map of the two continents, and situates them in the context of the politics and economics of the “frontier”.

Daniel Geiger is a doctoral candidate in Social Anthropology at the University of Luzern, Switzerland. He has lectured on political anthropology and indigenous movements. His research experience includes fieldwork in the Philippines and Indonesia. Under the auspices of the NCCR North-South, he has coordinated a comparative research project on conflicts between indigenous communities and settlers in South and Southeast Asia.

From Pattern to Process: New Approaches in Land Cover Research at the Regional Level in the Lower Mekong Basin

Andreas Heinimann, 2005

The present research project endeavors to further exploiti the static land cover inventories in combination with regional spatial databases in order to find spatially explicit clues about what processes are responsible for changes observed at the regional scale in the Lower Mekong Basin. The approach is based on the assumption that the geometrical patterns of land cover and land cover dynamics can be indicators for ongoing active processes of change. Methods borrowed from landscape ecology may offer a possibility of quantifying the ability of the human eye to recognize patterns qualitatively. The patterns discovered in the land cover inventories of 1993 and 1997 in the Lower Mekong Basin are linked to hypothetical process groups. The linkage between geometrical pattern and hypothetical process of land cover change is based on expert knowledge systems, thorough meta-analysis of case studies and spatial analysis with regional representations of potential driving forces.

GIS based watershed classification in Lao P.D.R

Andreas Heinimann, 2006

The Mekong River Commission (MRC) elaborated a spatial explicit Watershed Classification (WSC) for the Lower Mekong Basin. Based on topographic factors derived from a high-resolution Digital Terrain Model, five watershed classes are calculated, giving indication about the sensitivity to resource degradation by soil erosion. An analysis of the WSC in conjunction with forest cover data revealed that the more the 37% of Laos can be considered as critical with regard to degradation risk by soil erosion. The WSC allows spatial priority setting for watershed management and generally supports informed decision making on reconnaissance level. In the conclusions the article focuses on general considerations when GIS techniques are used for spatial decision support in a development context.

Economic aspects of sanitation in developing countries.

Minh Hoang Van, Hung Nguyen-Viet, 2011

Improved sanitation has been shown to have great impacts on people’s health and economy. However, the progress of
achieving the Millennium Development Goals (MDGs) on halving the proportion of people without access to clean water and basic sanitation by 2015 has thus far been delayed. One of the reasons for the slow progress is that policy makers, as well as the general public, have not fully understood the importance of the improved sanitation solutions. This paper, by gathering relevant research findings, aims to report and discuss currently available evidence on the economic aspects of sanitation, including the economic impacts of unimproved sanitation and the costs and economic benefits of some common improved sanitation options in developing countries.

Confronting limitations

New solutions required for urban water management in Kunming City

Dong-Bin Huang, Hans-Peter Bader, Willi Gujer, Ruth Scheidegger, Roland Schertenleib, 2006

"Despite continuous investment and various efforts to control pollution, urban water environments are worsening in large parts of the developing world. In order to reveal potential constraints and limitations of current practices of urban water management and to stimulate proactive intervention, we conducted a material flow analysis of the urban water system in Kunming City. The results demonstrate that the current efficiency of wastewater treatment is only around 25% and the emission of total phosphorous from the city into its receiving water, Dianchi Lake, is more than 25 times higher than its estimated tolerance. With regard to the crisis of water quantity and quality, the goal of a sustainable urban water environment cannot be attained with the current problem-solving approach in the region due to the technical limitations of the conventional urban drainage and treatment systems. A set of strategies is therefore proposed. The urban drainage system in Zurich is used as a reference for a potential best-available technology for conventional urban water management (BAT) scenario in terms of its low combined frequency of sewer overflow."

Discrete Event Simulation for Exploring Strategies

An Urban Water Management Case

Dong-Bin Huang, Derek E. Chitwood, Willi Gujer, Peter Loukopoulos, Roland Schertenleib, Roland W. Scholz, Hansruedi Siegrist, 2007

"This paper presents a model structure aimed at offering an overview of the various elements of a strategy and exploring their multidimensional effects through time in an efficient way. It treats a strategy as a set of discrete events planned to achieve a certain strategic goal and develops a new form of causal networks as an interfacing component between decision makers and environment models, e.g., life cycle inventory and material flow models. The causal network receives a strategic plan as input in a discrete manner and then outputs the updated parameter sets to the subsequent environmental models. Accordingly, the potential dynamic evolution of environmental systems caused by various strategies can be stepwise simulated. It enables a way to incorporate discontinuous change in models for environmental strategy analysis, and enhances the interpretability and extendibility of a complex model by its cellular constructs. It is exemplified using an urban water management case in Kunming, a major city in Southwest China. By utilizing the presented method, the case study modeled the cross-scale interdependencies of the urban drainage system and regional water balance systems, and evaluated the effectiveness of various strategies for improving the situation of Dianchi Lake."

Global Change and Sustainable Development: A Synthesis of Regional Experiences from Research Partnerships

Hans Hurni, Urs Wiesmann, 2010

Humankind today is challenged by numerous threats brought about by the speed and scope of global change dynamics. A concerted and informed approach to solutions is needed to face the severity and magnitude of current development problems. Generating shared knowledge is a key to addressing global challenges. This requires developing the ability to cross multiple borders wherever radically different understandings of issues such as health and environmental sanitation, governance and conflict, livelihood options and globalisation, and natural resources and development exist.

Global Change and Sustainable Development presents 36 peer-reviewed articles written by interdisciplinary teams of authors who reflected on results of development-oriented research conducted from 2001 to 2008. Scientific activities were – and continue to be – carried out in partnerships involving people and institutions in the global North, South and East, guided by principles of sustainability. The articles seek to inform solutions for mitigating, or adapting to, the negative impacts of global dynamics in the social, political, ecological, institutional and economic spheres.

Re-evaluating the burden of rabies in Africa and Asia

Darryn L. Knobel, Sarah Cleaveland, Paul G. Coleman, Eric M. Fèvre, Martin I. Meltzer, François-Xavier Meslin, M. Elizabeth G. Miranda, Alexandra Shaw, Jakob Zinsstag, 2005

Rabies remains an important yet neglected disease in Africa and Asia. Disparities in the affordability and accessibility of post-exposure treatment and risks of exposure to rabid dogs result in a skewed distribution of the disease burden across society, with the major impact falling on those living in poor rural communities, in particular children.

Integrated faecal sludge treatment and recycling through constructed wetlands and sunflower plant irrigation

Thammarat Koottatep, Sukon Hadsoi, Chongrak Polprasert, 2006

"Faecal sludge (FS) from the on-site sanitation systems is a nutrient-rich source but can contain high concentrations of toxic metals and chemicals and infectious micro-organisms. The study employed 3 vertical-flow CW units, each with a dimension of 5×5×0.65 m (width×length×media depth) and planted with cattails (Typha augustifolia). At the solid loading rate of 250 kg total solids (TS)/m2.yr and a 6-day percolate impoundment, the CW system could achieve chemical oxygen demand (COD), TS and total Kjeldahl nitrogen (TKN) removal efficiencies in the range of 80–96%. A solid layer of about 80 cm was found accumulated on the CW bed surface after operating the CW units for 7 years, but no clogging problem has been observed. The CW percolate was applied to 16 irrigation sunflower plant (Helianthus annuus) plots, each with a dimension of 4.5×4.5 m (width×length). In the study, tap water was mixed with 20%, 80% and 100% of the CW percolate at the application rate of 7.5 mm/day. Based on a 1-year data in which 3 crops of plantation were experimented, the contents of Zn, Mn and Cu in soil of the experimental plots were found to increase with increase in CW percolate ratios. In a plot with 100% of CW percolate irrigation, the maximum Zn, Mn and Cu concentrations of 5.0, 12.3 and 2.5 mg/kg, respectively, were detected in the percolate-fed soil, whereas no accumulation of heavy metals in the plant tissues (i.e. leaves, stems and flowers) of the sunflower were detected. The highest plant biomass yield and oil content of 1000 kg/ha and 35%, respectively, were obtained from the plots fed with 20% or 50% of the CW percolate."

Wastewater Effluent Polishing Systems of Anaerobic Baffled Reactor Treating Black-water from Households

Thammarat Koottatep, Antoine Morel, Atitaya Panuvatvanich, 2006

"This paper presents the outcomes of pilot-scale experiments on anaerobic baffled reactor (ABR) and polishing systems for the treatment of domestic blackwater, aimed at determining the treatment performance of different integrated low-cost wastewater treatment systems, comprising one ABR as first treatment step followed by three polishing steps operated in parallel, namely an anaerobic filter an intermittent sand filter and a vertical flow constructed wetland. A mixture of septage and domestic wastewater was used as influent wastewater, resulting in influent chemical oxygen demand (COD) and biochemical oxygen demand (BOD) concentrations of 1,000 and 300 mg/L, respectively. The ABR system operated at a HRT of 48h could achieve average COD, suspended solids (SS) and total nitrogen (TN) removal efficiencies of 90%, 93% and 50%, respectively. The highest treatment performances in the sand filter and constructed wetland units were reached at HLR of 7 – 10 and 6 – 10 cm/day, respectively, while HRT in the range of 3 - 4 days led to the highest treatment efficiencies in the anaerobic filter. The national effluent standards of Thailand were respected by all systems in terms of average TSS and BOD concentrations. Rather than concluding which system is the most appropriate, the paper discusses specific fields of application for the different systems."

Wastewater Management in Kunming, China

A Stakeholder Perspectives on Measures at the Source

Edi Medilanski, Liang Chuan, Tove Larsen, Hans-Joachim Mosler, Roland Schertenleib, 2006

"Large sewer systems with central wastewater treatment plants were long considered a successful model that could be exported to practically any city of the world. This centralized, highly water-consuming system has, however,
shown its limits in some developing and transition countries, especially in fastgrowing cities with limited water resources. This study from around Lake Dianchi in Yunnan, China, investigated the feasibility of introducing measures at the source for the different urban wastewater contributions in the city of Kunming, and the stakeholder perspectives on this approach. In addition, the stakeholders evaluated the potential of two different sanitation alternatives that allowed the separation and re-use of human excreta as fertilizer."

Who Counts? The Demography of Swidden Cultivators.

Ole Mertz, Vu Kim Chi, Carol J. P Colfer, Wolfram Dressler, Michael Epprecht, Andreas Heinimann, Stephen J Leisz, Christine Padoch, Lesley Potter, Kanok Rerkasem, Dietrich Schmidt-Vogt, Thiha Thiha, Pham Van Cu, 2009

Swidden cultivators are often found as a distinct category of farmers in the literature, but rarely appear in population censuses or other national and regional classifications.
This has led to a worldwide confusion on how many people are dependent on this form of agriculture. The most often cited number of 200–300 million dates back to the early 1970s, but the source is obscure. We assess available, published data from nine countries in Southeast Asia and conclude that on this basis it is not possible to provide a firm estimate of the number of swidden cultivators in the region. A conservative range of 14–34 million people engaged in swidden cultivation in the region is suggested, however. We argue that along with improved knowledge of swidden livelihoods, there is an urgent need to develop techniques that will allow for better estimates of swidden populations in order to secure appropriate rural development and poverty reduction in swidden areas.

Assessing nutrient flows in septic tanks by eliciting expert judgement

A promising method in the context of developing countries

Agnes Montangero, Hasan Belevi, 2007

"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."

Where Are the Poor and Where Are the Trees?

Targeting of poverty reduction and forest conservation in Vietnam

Daniel Müller, Michael Epprecht, William D. Sunderlin, 2006

"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."

[...] With the current research, a Mathematical Material Flow Analysis (MMFA) is applied as an alternative approach to conventional river water quality models. Applied to analyze river water polllution, the MMFA allows to trace the pollution flows and their transformations from their input to the system as resource, through waste production, separation, treatment and finally to their outputs as product or as discharge into receiving water bodies. In this way, the perspective is widened to grasp the river system in an overview and to understand the origins and the main processes involved in the chain of nutrient pollution generation. The key parameters influencing the pollution flows are determined, based on which concrete and effective mitigation measures can be devised and evaluated. [...]

Assessment of water quality problems and mitigation potentials by using material flow analysis

A case study in the Tha Chin river catchment, Thailand

Monika Schaffner, Hans-Peter Bader, Thammarat Koottatep, Agnes Montangero, Ruth Scheidegger, Roland Schertenleib, 2005

"Material flow analysis (MFA) is a promising tool for river water quality management. Based on orders-ofmagnitude estimations, the approach provides an overview of pollution problems and their dimensions in a river system, allowing to identify key sources and pathways of pollution, and to evaluate mitigation priorities. The current study aims at investigating MFA to assess river water quality problems and mitigation measures in developing countries, based on a case-study carried out in the Tha Chin River Basin (TRB), Thailand."

Modeling non-point source pollution from rice farming in the Thachin River Basin

Monika Schaffner, Hans-Peter Bader, Ruth Scheidegger, 2011

With the worldwide intensification of agriculture, non-point source pollution of surface waters has become a pressing issue. Conventional river water quality models consider non-point sources as accumulated entries into the rivers and do not investigate into the processes generating the pollution at its source, thus preventing the determination of effective mitigation measures. The models require extensive data inputs, which is a deficiency in many developing and emerging countries with limited data availability. The current study applies a Material Flow Model as a complementary approach to quantify non-point source pollution from agricultural areas. Rice farming in the Thachin River Basin is presented as a case study, with a focus on nutrients. The total nitrogen and phosphorus flows from rice farming to the river system are quantified, the key parameters influencing these flows are determined and potential mitigation measures are discussed. The results show that rice contributes considerable nutrient loads to the Thachin River Basin. Scenario simulations demonstrate that a significant nutrient load reduction could be achieved by following the official recommendations for fertilizer application, thus confirming the local efforts to introduce best management practice. Our results underline the importance of non-point source pollution control in intensive agricultural areas, particularly of tropical lowland delta areas such as the Central Plains of Thailand. The specific benefit of applying a Material Flow Model in this context is that with limited data availability, one can reach an understanding of the system and gain a first overview over its key pollution problems. This can serve as supportive basis for determining consecutive in-depth research requirements.

Modeling the contribution of pig farming to pollution of the Thachin River

Monika Schaffner, Hans-Peter Bader, Ruth Scheidegger, 2009

Rapid growth of the livestock production sector in South-East Asia during recent decades has led to a widespread degradation of ground and surface waters. The Thachin River Basin in Central Thailand serves as a case study for investigating the origins and pathways of nutrient loads produced by intensive pig farming. A mathematical material flow analysis is used to identify key nitrogen flows and the main parameters determining them. Scenarios of the potential for reducing these flows and achieving compliance with current discharge regulations are investigated. The results show that liquid waste discharged from large pig farms and directly discharged waste from small farms are the key nitrogen flows to the river system. The key driving forces are not only the treatment coverage and efficiencies but also the rate of reuse and recycling of the treated product.

The Tha Chin River is Overloaded with Nutrients

Monika Schaffner, Ruth Scheidegger, Irene Wittmer, 2007

"Increasingly intensive farming practices have led to a dramatic deterioration of water quality in the Tha Chin River in Thailand. One major problem is the high level of nutrients. According to our model – based on material flow analysis – intensive aquaculture accounts for a large
proportion of the nutrient inputs."

Coping on women’s back: Social capital-vulnerability links through a gender lens

Susan Thieme, Karin Astrid Siegmann, 2007

Processes of migration are embedded in social networks, more recently conceptualised as social capital, from sending households to migrants’ formal and informal associations at their destinations. These processes are often assumed to reduce individuals, households and economies’ vulnerabilities and thus attract policy-makers’ attention to migration management. The paper aims to conceptualise the gendered interface between social capital and vulnerability. It utilises Bourdieu’s notion of social capital as an analytical starting point. To illuminate our conceptual thoughts we refer to empirical examples from migration research from various Asian countries.
Bourdieu’s theory highlights the social construction of gendered vulnerability. It goes beyond that by identifying the investment in symbolic capital of female honour as an indirect investment in social and, ultimately, economic capital.

Research for Sustainable Development: Foundations, Experiences, and Perspectives

Urs Wiesmann, Hans Hurni, 2011

Achieving sustainable development requires knowledge-based and value-conscious social, political, and economic decisions and actions at multiple levels. Research aiming to support sustainable development must co-produce knowledge at the interfaces between disciplines, between science and society, between knowledge cultures in the global North, South, and East, and between global visions and local realities, while remaining rooted in solid disciplinary foundations. Research for Sustainable Development presents 29 articles in which interdisciplinary teams reflect on the foundations of sustainability-oriented research, on concepts, tools, and approaches to overcome the challenges of such research, and on specific issues of sustainable development.

Modelling the Water and Nutrient Flows of Freshwater Aquaculture in Thailand

A material flow analysis

Irene Wittmer, 2005

Master's Thesis, Swiss Federal Institute of Technology Zurich, Switzerland

"The Tha Chin River Basin (central Thailand) faces major water quality problems. Among others, freshwater aquaculture was identified to be one of the pollution sources. This study looks at nutrient loads coming from freshwater aquaculture systems in the area. A model based on a material flow analysis was set up to quantify the loads to canals and rivers as well as to identify the key factors (parameters) that influence the system. The focus was placed on four different major cultivation systems. For all four considered systems, the amount of feed and nutrient concentrations in feed have the highest influence on the nutrient loads to the canal. [...]"


Metropolization and the Ecological Crisis

Precarious settlements in Ho Chi Minh City, Vietnam

Sebastian Wust, Jean-Claude Bolay, Ngoc Du Thai Thi, 2002

"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."
