Research connected to South Asia:
Professor Emeritus Gunnar Jacks has been engaged in research on water issues in South India since the late 1960’s, when he first visited Coimbatore in Tamil Nadu and established a long-standing relation with Tamil Nadu Agricultural University. Over the decades a large number of students from the Dept. of Land and Water Resources Engineering at KTH have gone to Coimbatore to do field work for theses.
Prof. Jacks is still involved with a major water resources management project in South India, in collaboration with the Department of Water and Environmental Studies, Linköping University, and SACIWaters, Hyderabad, India. More information on this project.
Gunnar Jacks graduated as a mining engineer from KTH in 1963. After working with rock stability issues for a couple of years he and his wife Birgitta spent a year with a humanitarian Non-Governmental Organization (NGO) in Turkey where he realized the importance of water for societies and human life. He took a B. Sc. degree in Medicine from the Karolinska Institutet, Stockholm in 1971. After returning to Sweden and KTH, he studied hydrology and received the PhD in hydrochemistry in 1973.
A turning point was when he assisted his professor in a short term groundwater investigation in Tamil Nadu, India. That led to a three year project work within Central Ground Water Board in Coimbatore in India and later on to an engagement in a project in Kerala, India. The chemistry of fluoride in groundwater was a major subject of his research interest and together with his Indian colleagues, he has published a number of research articles. While he has throughout years been a faculty member at KTH he has been on missions to Botswana, Vietnam, Thailand, and Laos.
In 1985, he got a professorship in Groundwater Chemistry. He took a very active part in teaching and research on acidification of soil and groundwater during the 1980s and 1990s. The quantitative study of weathering rates became an important issue and he was part of a group that used strontium isotopes for assessments. During this period he was also doing research on artificial recharge of groundwater as well as wetland hydrology and hydrochemistry. He has been involved with a number of international research projects since 1990s which include investigation on high fluoride groundwater in Rajasthan, India (1994–1997), and local water supply and sanitation in suburban Dhaka, Bangladesh (1999–2003).
He has supervised a significant number of PhD students during his professional career at the KTH and serve as a peer-reviewer in a number of scientific committees and peer-reviewed journals. Professor Jacks been actively involved in research on arsenic in soil and groundwater systems since 1991. During 1996, his research group at KTH was contacted by Dr. Debashis Chatterjee from the Kalyani University situated near Kolkata, India regarding the arsenic problems in West Bengal. That was the start of a still ongoing work in India, Bangladesh and several other parts of the world with a principal focus on research on the mechanisms of arsenic mobilization in groundwater environments, a work now headed by Prof. Dr. Prosun Bhattacharya (more information below).
Gunnar Jacks is a guest professor at Åbo Akademi University, the Swedish speaking university in Finland. In 2006, he was elected as the President of the International Society of Groundwater for Sustainable Development (ISGSD). Gunnar Jacks was also instrumental in setting up of SASNET, and was a member of the SASNET board till 2003.
He presented his research on ”Water supply – from the source to the mouth” at the Swedish Development Studies research conference, named ”Fattiga och rika. Aktuell utvecklingsforskning och dess villkor i Sverige”, organised by Sida/SAREC and Lund University on 9–11 January 2003. Read the abstract. Jacks also organised a panel at the 18th European Conference on Modern South Asian Studies organised by SASNET and Lund University in July 2004. The panel was named ”Industrialisation in South Asia – economic, social and environmental aspects”. Full information on the panel.
In November 2005 Prof. Jacks received a one-year research grant from Sida/SAREC for a project titeld ”Risk for sea water intrusion in the Kerala coastal aquifers”. The other partners in the project are Mattias von Brömssen at the same department; plus Warrier C. Unnikrishnan, and P. S. Harikumar from the Centre for Water Resources Development and Management (CWRDM), Kozhikode, Kerala, India. The cooperation with CWRDM was set to continue from October 2008 with the investigation of groundwater around Vembanad Lake and its connection with the brackish estuary.
Project abstract: Kerala Coastal aquifers on the SW part of the Indian peninsula range from Tertiary to Holocene in age. The Tertiary aquifers are found in the coastal sediments formed when the Indian peninsula was largely drained westwards. The deeper aquifers have a sequence from the south of calcium -bicarbonate water via sodium-bicarbonate water to a brackish water in the north. The fresh aquifers are subject to overdraft with risk of salt water intrusion. However, the presence of sodium-bicarbonate water indicates flushing out of a former saline/brackish water. The hypothesis is that thios reflects flushing during glacial times when the sea water level was 125 m below the present one. The project aims at dating the groundwater. If the hypothesis is verified the risk for sea water intrusion is less alarming as the salt water/fresh water interface might be off-shore.
In August 2006, Prof. Jacks was given SEK 20 000 as a SASNET grant to cover a guest lecture programme to bring Dr. Alagappan Ramanathan, Dept. of Environmental Sciences, Jawaharlal Nehru University (JNU), New Delhi, India, to Sweden (more information about the SASNET grants 2006).
In November 2007, Prof. Jacks was given SEK 600 000 as a three-years grant (2008-10) from Sida’s Developing Country Research Council (U-landsforskningsrådet), for a project titled ”Fluoride contamination in groundwater (Karnataka, India): A community effort in cost-affective treatment and management”. The project is a cooperation between Associate Professor Joyanthi Routh at the department of Geology and Geochemistry, Stockholm University, and Professor B.S. Choudri at TERI Institute, Goa, India. More information about the Sida grants 2007.
Prof. Jacks is also involve din a research project on ”System for Rice Intensification – saving water and producing more?” in collaboration with Dr. Nilanjan Ghosh from the MCX Academy for Commodity Research (MACOR) in Mumbai, India. At the Sida-funded conference on current Swedish development research titled ”Meeting Global Challenges in Research Cooperation” that was jointly organised by Uppsala Uppsala University and the Swedish University of Agricultural Sciences (SLU) in Uppsala 27–29 May 2008 (more information), Prof. Persson presented a paper on the project in a panel on ”Sustainable, productive and efficient agriculture – an impossible match?”.
Abstract: Rice is the staple food for a large fraction of the global population. Wetland rice requires about 1 200-1 400 mm of water per crop. However, in the early 1990s Father Henri de Laulanie, engaged in rice cultivation on Madagascar, published his experiences from a drought period when the lowland rice could not be kept flooded (Laulanie, 1993). He found that the yield increased although the applied irrigation water was only about half the conventional amount. This interesting finding has initiated experiments especially in Asia, in China and India notably. There has been harsh criticism against the practice using words such as
nonsense and no science. The growing experience in the practise both supports the claim that yields are higher and denies it. Several advantages are registered like a better nitrogen economy as denitrification decreases. Further, emissions of greenhouse gases like dinitrogen oxide and methane decrease. What has further been debated is the labour requirement. SRI uses a different planting pattern and requires more frequent mechanical weeding. Adopting the practise requires considerable extension
work and regard to seasonal financial constraints for poor farmers. The advantages documented regarding water efficiency, nitrogen economy, environmental impact and returns for the farmers indicate that SRI is a promising practise especially where water is a constraint. It seems that a successful adoption requires a considerable extension work.
A separate KTH-International Groundwater Arsenic Research Group, GARG (Forskargruppen för miljögeokemi) within the department is studying contaminated groundwaters and soils. GARG is presently engaged in research projects concerning the arsenic problem in the Bengal Delta Plain. Some of these studies deal with arsenic in groundwater, which is a very serious problem to inhabitants of the Indian state of West Bengal, and Bangladesh. In these areas some 33 million inhabitants are using arsenic-contaminated water daily; about 200,000 of them are displaying symptoms of arsenic poisoning.
The main research issues are to find out how the arsenic in the sediments is dissolved and gets into the groundwater, and the methods for the removal of arsenic. Before remediation methods are put into practice, investigation of their long-term implications are made, as well as which chemical constituents in the groundwater may affect the different methods of arsenic removal.
One of the major targets is to develop low-cost and sustainable methods for the removal of arsenic from contaminated water. They should be viable on a small scale, to be used in villages or small communities. Further, GARG studies the groundwater composition from different aquifers of Bangladesh, which will serve as a basis for finding arsenic-safe groundwater sources for sustainable drinking water supply. More information on GARG.
The arsenic research carried out has been funded by Sida/SAREC, and the United Nations Children’s Emergency Fund (UNICEF) during the period 1999–2006, and the Swedish Strategic Environmental Research Foundation (Mistra) for the period 2006–2009.
Professor Prosun Bhattacharya (photo to the left) is the leading researcher at the department presently engaged in research projects on arseniferous groundwater in India and Bangladesh.
Basic research is going on. The current work is still partly in the stage of characterizing the aquifers, from which arsenic is mobilized. A relation that has been confirmed is that groundwater contains a significant quantity of dissolved iron, a fact that is related to its high levels of arsenic. The chemical environment in the delta sediment often makes the ferric oxides, i e rust, to dissolve and thereby mobilizes arsenic, which is adsorbed to the oxides. This means that water containing much arsenic may be remediated. One method is to add oxygen to the water; this makes the iron precipitate as ferric oxide, which will then adsorb the arsenic on its surfaces, making the water drinkable. Another method now employed is to mix laterite, a kind of soil available in large quantities in West Bengal, with the water. This binds some 80 to 90 per cent of the arsenic in soil.
Arsenic in groundwater of Bangladesh and India has been focus for research at the department for several years. They have tried to find out why groundwater in certain parts of Bangladesh and adjacent areas are contaminated while others are not. The sediments, i e the soil layers, are also being examined. Obviously, the geological features as well as the changes of the chemical environment determine the contents of arsenic; it has already been found that younger, more shallow layers contain more arsenic than older, deeper ones do. This explains why groundwater from more shallow wells do contain more arsenic than deeper ones. Consequently, one solution would be to drill deeper wells.
Other projects have focused on mapping the acquifers (groundwater-carrying sediment layers) with an aim at making it easier to find where existing wells can be drilled deeper in order to reach aquifers where the arsenic content is lower.
Arsenic-contaminated water in different parts of the world. The research in Bangladesh and West Bengal will also result in knowledge that may be used in other areas with arsenic-contaminated waters as well. Two of these are the Huhhot Alluvial Basin of inner Mongolia and the Chaco-Pampas Plains of the Argentine. Alarming reports about arsenic-contaminated waters are also coming from China, Thailand, Vietnam and Taiwan; evidently, the development of sustainable methods to purify contaminated groundwaters is urgent.

Gunaratna, Dept. of Environmental Microbiology, KTH; Prof. Al. Ramanathan from the School of Environmental Sciences, Jawaharlal Nehru University (JNU), New Delhi, India; Prof. Chandan Mahanta, Indian Institute of Technology (IIT), Guwahati, India; and Dr. D. Chandrashekharam, Department of Earth Sciences, Indian Institute of Technology (IIT) Bombay, India.
In June 2007, Prof. Prosun Bhattacharya received SEK 909.900 for a three-years project (2008-10) titled ”Groundwater arsenic in Chhattisgarh, Central India and options for sustainable arsenic-safe drinking water supplies”, as a Joint Formas–SAREC grant for research on sustainable development in developing countries. The grant is jointly provided by the Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS), and the Department for Research Cooperation (SAREC) within the Swedish International Development Cooperation Agency (Sida). The project will be carried out in collaboration between the KTH-International Groundwater Research Group, and Pandit Ravi Shankar Shukla University (PRSU) in Raipur, Chattisgarh state, India. The project coordinator on the Indian side is Professor K.S. Patel, School of Studies in Chemistry, PRSU.
Project Summary: Groundwater is the main source of potable water for the population in South Asia. In India, the presence of arsenic (As) above the limits of safe drinking water (10 μg/L) detected in groundwater widely over the Indian subcontinent has posed to be a potential source of environmental health disaster. The presence of As in the groundwater of the hard rocks aquifers in the district of Rajnandgaon in Chhattisgarh state has exposed an estimated population of 1-2 million to a potential risk of arsenic exposure. Arsenic contamination in tube-well water in Ambagarh-Chowki block in Chhattisgarh state of central India, is restricted to local areas confined within the N-S trending Dongargarh rift zone. Affected areas are preferentially located in acid volcanics, close to shear zones. As preferentially occurs in iron-enriched soil and similarly altered biotite, chlorite in granite. Pyrite in volcanic and shear zone rocks, although locally As-bearing also acts as a source of As in groundwater.
The overall objective of the present project is to consolidate the information and database on the groundwater resources for exploitation of safe-drinking water in As affected hotspots in selected areas of Rajnandgaon district in Central India. The specific goal of this project is to develop the options for targeting As-safe aquifers for drinking purposes that involves detailed evaluation of the local geological and hydrogeological setting in order to: i) identify geological and Hydrogeological baseline study in the region, and ii) to provide and develop common scientific database on baseline hydrogeochemistry of the aquifers for the identification of As-safe and targeting the As-safe aquifers for drinking water supply. Within the framework of this project, we also aim to use the hydrogeological and geochemical constraints in the hot-spot areas as a basis for the evaluation of the risks associated with these aquifers, and thereby their sustainability as safe drinking water source. The co-operation involves exchange of scientific personnel, fieldtrips, seminars, jointly supervised Ph.D. and M.Sc. projects and publication of research articles.
Later the same year, in December 2007, Prof. Prosun Bhattacharya and his GARG collaborators received SEK 9.4 million as a major grant from the Department of Natural Resources and the Environment within the Swedish International Development Cooperation Agency (Sida), for a four-years project (2007-10) titled ”Sustainable Arsenic Mitigation (SASMIT). Community driven initiatives to target arsenic safe groundwater as sustainable mitigation strategy”. The project is carried out in collaboration with the University of Dhaka, the NGO Forum for Drinking Water Supply & Sanitation (based in Dhaka, Bangladesh), other partners at the Royal Institute of Technology (KTH) in Stockholm, and the private company Ramboll Natura AB, an international consultancy firm in the field of sustainable development, with focus on environment and natural resources management; forests, land and water resources. Ramboll Natura has worked in over 70 countries and is part of the Ramböll Group, the largest Nordic provider of knowledge services within engineering, management, IT and international development projects (more information about Ramböll Natura). The main objectives of the project are to i) increase global awareness of the problems associated with high arsenic groundwater of geogenic origin, ii) exchange experiences regarding feasibility of mitigation options and iii) develop a sustainable option for safe drinking water for rural and disadvantaged communities, through targeting safe aquifers in regions with high arsenic groundwater of geogenic origin for installation of community hand tube wells. Action research is conducted in Matlab Upazila, Bangladesh (from where the photo is taken). Read the complete project proposal.

Mattias von Brömssen (photo) now works as Department Manager at Ramböll Sweden in Stockholm, at its Department for Soil and Water Environment. He defended his doctoral dissertation entitled ”Hydrogeological and geochemical assessment of aquifer systems with geogenic arsenic in Southeastern Bangladesh – Targeting low arsenic aquifers for safe drinking water supplies in Matlab” on Friday 20 January 2012. The faculty opponent was Professor David Polya, University of Manchester, United Kingdom. The thesis covers a crucial period of the work on the arsenic problems in groundwater in Bangladesh. Especially it includes the discovery of the local drillers ́ strategy to find low iron groundwater by assessing the colour of the sediments. With the link between mobilisation of arsenic along with iron which was published by a KTH team in 1997 this gave an immediate hint on means of predicting arsenic low groundwater during well construction. The strategy was discovered by the author of the thesis when he was advising a M.Sc. thesis project. The “sediment colour strategy” leads to a number of questions that has to be answered, notably the risk of cross contamination of arsenic low sediment sequences. Essentialy three crucial issues are dealt with in the thesis, the groundwater flow pattern, the adsorption characteristics and redox buffering of the low arsenic layers. The insight gained indicates that the strategy of finding low arsenic aquifers is sustainable. The methods used comprised of groundwater and sediment sampling, detailed chemical analysis of water, sediment extractions, mineralogical investigations and hydrogeochemical- and groundwater flow modelling. However, the groundwater extraction for irrigation is a threat in the way it is practised today and would be even more so if low arsenic deep wells are constructed for the purpose.

Md. Jakariya from BRAC Arsenic Mitigation Project, Bangladesh Rural Advancement Committee (BRAC) in Dhaka, Bangladesh defended his doctoral dissertation titled ”Arsenic in Tubewell Water of Bangladesh, and Approaches for Sustainable Mitigation” on Thursday 24 May 2007. The faculty opponent was Prof. Jan Hoinkis, University of Applied Sciences in Karlsruhe, Germany. The thesis dwells on the central issue of devising different strategies for As mitigation and to find their sustainability and rational distribution to the affected population and to meet the safe water target of the Millennium Development Goal (MDG). Importantly, the issues identified in the thesis for further research will develop common global approaches for sustainable mitigation and management of As in drinking water.
Dr. Jakaiya was supervised by Prosun Bhattacharya. Read the full dissertation (as a pdf-file)
Md. Aziz Hasan from the Dept. of Geology, University of Dhaka, has also done a PhD at the department, supervised by Prosun Bhattacharya. He defended his doctoral l dissertation titled ”Arsenic in alluvial aquifers in the Meghna basin, South-Eastern Bangladesh: Hydrogeological and geochemical characterisation” on Wednesday 5 November 2008. The study reveals that the local and regional scale variations in groundwater composition, levels of As concentrations and the redox conditions are governed by the geological attributes of the aquifers. Groundwater in the grey to dark grey argillaceous sediments where organic matter and micas are abundant contain high concentration of dissolved As. High concentrations of As and salinity are the major constraints for groundwater development in the Holocene alluvial aquifers of the Meghna basin. Abstraction of groundwater from the Holocene deeper low-As aquifers for drinking purposes should thus be be properly guided to minimise the risk of cross-contamination and installation of high-capacity irrigation wells in the deeper aquifers must be avoided for sustainable drinking water supplies. Read the full dissertation (as a pdf-file).
Currently, PhD candidate Mohammed Hossain Tipu from the University of Dhaka, carries out research at the department, also supervised by Prosun Bhattacharya. Mr. Hossain is working for the NGO Forum in Bangladesh, and is national coordinator for the Sustainable Arsenic Mitigation (SASMIT) project research project, mentioned above.
Arifin Sandhi (photo) joined the department in September 2011 as a PhD student, after completing a Masters in Ecology from Stockholm University in 2011, and before that a Bachelors degree in Agril. Science from Sher-e-Bangla Agricultural University (SAU) in Dhaka, Bangladesh in 2007.

Arifin is now working in the KTH-GARG (Global Arsenic Research Group) with a PhD project entitled ”Assessment of arsenic and manganese of in the soil and groundwater and accumulation in rice”.
He is supervised by Professor Prosun Bhattahcharya and Professor Emeritus Gunnar Jacks at his own department, plus Professor Maria Greger at Stockholm University. The project is financed by Swedish International Development Cooperation Agency (Sida).
Abstract: Presence of high level of arsenic in groundwater and soil is one of the major problems in Bangladesh. A number of divergent carcinogenic diseases occurred by this toxic trace metalloid. Besides arsenic, high level of manganese in the groundwater also considered one of the potential health threats. The agricultural system of Bangladesh depends on groundwater based irrigation system. Due to this irrigation activity, high level of arsenic and manganese comes to the top soil and it becomes more bioavailable for the crop plant species.
A significant number of studies have done in the arsenic affected areas in Bangladesh to mitigate the arsenic contamination from the drinking water. Compared with drinking water contamination, arsenic accumulation through food crops not focused much. Besides drinking water, by consumption of arsenic enriched food crop and grain also become one of the major pathways of arsenic in the human body.
Ashis Biswas, originally a student in Analytical Chemistry from the University of Kalyani, West Bengal, India, defended his doctoral dissertaition entitled ”Delineation of safe aquifer and its sustainability in arsenic affected region of West Bengal, India” on 23 September 2013. Faculty opponent was Prof. Dr. Laurent Charlet, CNRS, University of Grenoble, Grenoble, France. Abstract: The thesis describes the natural occurrences of high dissolved arsenic (As) in groundwater of Bengal Basin that has put millions of people under the threat of chronic As exposure through drinking water. Present study has examined the processes that regulate As mobilization and its distribution in shallow aquifers and the potentiality of finding safe aquifers within shallow depth (<50 m) for drinking water supply. This study concludes that the reductive dissolution of Fe oxyhydroxides followed by competitive sorption reactions with the aquifer sediment is the process conducive for As enrichment in groundwater of Bengal Basin.

Ashis Biswas came to KTH as a scholarship holder of the Erasmus Mundus External Cooperation Window programme EURINDIA. His principal adviser was Prof. Prosun Bhattacharya, but the co-Adviser Group consisted also of Prof. (Em.). Gunnar Jacks; Prof. Debashis Chatterjee (University of Kalyani, India); Prof. Kazi Matin Ahmed (University of Dhaka, Bangladesh); Dr. Abhijit Mukherjee (IIT-Kharagpur, India); and Dr. Bibhash Nath (The University of Sydney, Australia). Biswas has now returned to India.
Dipti Halder has the same background at Kalyani University, India, and was financed by the Eurindia mobility programme. She defended her doctoral dissertation project entitled ”Evaluation of Dietary Arsenic Exposure in Arsenic Affected Regions of West Bengal, India” on the 25 September 2013. Faculty opponent was Prof. Dr. M. Alauddin, Department of Chemistry, Wagner College, Staten Island, NY, USA. and her supervisor has been Prof. Prosun Bhattacharya.
Abstract: The thesis investigates the risk of arsenic (As) exposure from staple diet to the communities in rural Bengal, even when they have been supplied with As safe drinking water. The results indicate that average accumulation of As in rice grain increases with decrease of grain size, however people living in the rural villages mostly prefer brown colored SB type of rice because of its lower cost. Among the vegetables generally consumed in rural villages, the accumulation of As is highest in the leafy type of vegetables, compared to non-leafy and root vegetables. The study suggests that any effort to mitigate the As exposure of the villagers in Bengal must consider the risk of As exposure from rice consumption together with drinking water.

Dipti Halder ha snow returned to India.
Research scientist Nandita Singh, is involved in a project on “Problems and Prospects of Sustainable Water Resources Management in India: An Insight from Gender Perspective”. The project focuses on the issue of water in the now severely water-stressed Indian state of Gujarat, where the seriousness of the problem warrants its exploration not only from the gender perspective but essentially also as a human rights concern. The problems encountered by the local communities in the northern part of the state are unique in combining deficiency of water with high fluoride rates in drinking water, resulting in concomitant gender and socio-economically disaggregated impacts on their lives. Additional research projects will be designed in the future so as to enable research on the remaining issues of concern.
Partners in the project are (in Sweden) Prosun Bhattacharya and Jan-Erik Gustafsson, and (in India) Professor Jayanto Bandopadhyay, Centre for Development and Environment Policy, India Institute of Management, Kolkata, and Research Associate Vishar Narain, Resource and Development Economics, Policy Analysis Division, Tata Energy Research Institute, New Delhi. Nandita Singh received a SASNET planning grant from SASNET in January 2003 for this project. Preliminary findings emerging from the planning visit to the field in 2003 enabled Singh to formulate two research papers presented at the 18th European Conference on Modern South Asian Studies held in Lund 6–9 July 2004. In recent years she has also worked on two similar research project on women and gender in India: One on ”Women and water: Need for a holistic and sustainable policy” (funded by the Wenner-Gren Foundation 2002-04), and another one on ”Women and Water: Encountering the challenges of water resource management in rural India from gender perspective” (funded by Sida/SAREC 2003-05).
In August 2005 Nandita Singh again received a SASNET planning grant for an interdisciplinary research project related to the issue of sustainable water management in India. More information on the August 2005 SASNET grants.
The new project is named ”Relevance of socio-cultural context in realization of the human right to water in India: An insight from gender perspective”, and will be planned for in collaboration with the Department of Sociology of Law, Lund University (contact persons Professor Prof. Karsten Åstrom, Professor Håkan Hydén, and Associate Professor Per Wickenberg); the National Institute of Human Rights at National Law School of India University in Bangalore, India (contact person: Sarasu E. Thomas, Coordinator); and SEWA Academy (Self-Employed Women’s Association), SEWA, Ahmedabad, India (contact person: Namrata Bali, General Secretary).
In November 2005 Nandita Singh also received SEK 500 000 as a one-year grant from Sida/SAREC for this project.
Abstract of project: The right to water is an important human right within the category of economic, social & cultural rights where special attention is paid to women as a group traditionally facing difficulties in exercising the right. However, large-scale violations of the right are reported to persist in the developing world, India being a significant case where despite positive actions by the state towards its protection & fulfilment with focus on women, a substantial number of them are unable to enjoy the right effectively. This planning project will explore the hypothesis that the origin of the problem lies in factors embedded within the socio-cultural context of the women, that play a critical role at the ‘third’ level of implementation of human rights law – at the ‘interface’ between the state and the local actors. An understanding of the nature of the factors is aimed to be developed through the planning exercise, coupled with identification of micro-level specificities in this connection through joint planning exercises with the partners in India who have knowledge and experience in relation to human rights and women’s development. An interdisciplinary insight on the problem, based in Anthropology and Sociology of Law, is expected to enable more comprehensive understanding and interpretation as well as facilitate formulation of an integrated strategy for overcoming the barriers in the Indian context that will constitute the final objective of the proposed research.
At the Sida-funded conference on current Swedish development research titled ”Meeting Global Challenges in Research Cooperation” that was jointly organised by Uppsala University and the Swedish University of Agricultural Sciences (SLU) in Uppsala 27-29 May 2008 (more information), Dr. Singh presented the project in a panel on ”Water and Sanitation”. Her paper was titled ”Meeting the MDGs through the Human Right to Water – A gendered analysis in India from actor oriented perspective”. She also presented a photo exhibition along with her husband, Mr. Om Prakash Singh (seen on the photo to the right), on the water problems the citizens of Delhi face. The exhibition was titled ”Human Right to Water – Reality or a Fantasy?”
Abstract: One of the targets of the UN Millennium Development Goals (MDGs) is to halve the number of people without sustainable access to safe drinking water by 2015. It is believed that one of the ways to add impetus to the ongoing efforts is to explicitly recognize water as a ‘human right’, with a focus on ensuring the right of women and children, who are seen to be the worst sufferers from lack of sustainable water access. It is assumed that focus on the human right to water (HRW) would serve as a means to increase the pressure on governments and international agencies to translate the right into specific national and international legal obligations and responsibilities, thus paving the way for ensuring water access for all (UNESCO, 2006).
This assumption has been examined by the authors within the scope of two different research projects supported by Sida-Sarec. Using an actor-oriented perspective that further made a distinction between ‘implementation’ and ‘realization’ of human rights, these projects attempt to understand how the globally formulated norms concerning water as a human right get translated
into action at the local level. The first project looked at the HRW of women while the second one focuses on the right of children. The research is based upon empirical studies in different parts of India and refers to the right to water situation in areas affected by problems of water quality and quantity.
The findings of the research indicate that realization of HRW essentially involves dynamics at the ‘third level’ of human rights implementation. This constitutes the interface between the community and the agency where action towards fulfillment of the right is ultimately unfolded. Following the rights-based approach to development, two kinds of actors were identified – the ‘rights-holders’ (women and children) and the ‘duty-bearers’ (government, NGOs, international development agencies). The contextual factors that influence the realization of the HRW of women and children as separate right-holder groups can be classified into two categories: first, the nature of human rights approach adopted by the agency (if any) and second, the socio-cultural factors in the community context that lead to re-construction of the right at the local level. The dynamics of interaction between the two sets of factors are complex and need to be understood as contextual realities. On the whole, the latter have been found to have significant influence on the equitable, effective and sustainable realization of the HRW.
From the preliminary findings of the research, it can be concluded that mere legislative actions at international and national forums for implementing the HRW may not offer enough benefits towards ensuring progress towards the MDGs. There is a need to explore the dynamics at the‘third’ level and consider how the learnings can be integrated into the global and state initiatives so as to promote water justice for women and children.
During the World Water Week 16-23 August 2008, Dr. Nandita Singh, along with her husband, Mr. Om Prakash Singh who is a visual anthropologist, presented a photo-exhibition titled ‘Urban Water Challenges’. The exhibition – that turned out to be one of the most highly visited stalls at the Week – was supported by the Swedish Water House. It displayed large-sized black and white photographs portraying the looming water crisis in Delhi both in terms of quantity and quality. Aimed at sensitising the various stakeholders who share a concern with water – the policy-makers, planners, other development actors and the research community – each photograph depicted a significant theme, including water corruption, gender sensitivity, gender equality, water conflicts, water pollution, children and water, sanitation and water scarcity.
Dr. Singh was also an invited speaker at the Seminar on the Right to Water and Sanitation – Approaches and Practical Implications, convened by SIWI, UNDP, Swedish water House, COHRE, SIDA and UN-Habitat. Her presentation, titled ‘Role of socio-cultural context in realization of the Right in India’, outlined the findings of her research on the right of women and children to water in India, carried out in collaboration with partners at the Division of Sociology of Law, Lund University and supported by Sida-Sarec.
Dr. Singh also presented a paper in the Workshop on ‘The lingering failure of sanitation-Why? Her paper titled ‘Total sanitation efforts in India: Problems and prospects’ invited wide attention as it highlighted the importance of looking at sanitation as an issue of ‘behavioural change’ that cannot be addressed through mere installation of sanitary infrastructure and counting of numerical targets.
On 19th September 2008, Dr. Singh, along with Prof. Karsten Åström from the Division of Sociology of Law, LU, have been invited to make a presentation at the Social Sciences Day Seminar on “Conflicts around Water: Struggle about our most important resource” organised by Lund University. Their presentation will be on the topic ‘Human right to water in India: Problems and prospects’ where using an actor-oriented perspective, the process of ‘realization’ of the right at the micro-level will be seen as influenced by two sets of contextual factors at the ‘interface’ between the duty-bearers and the right-holders, these being embedded in the implementation context introduced by the former and the socio-cultural contextlived in by the latter.
Dr. Nandita Singh is responsible for 7,5 credits course titled ”Gender issues in Developing Countries” that was first held in the Fall 2007. The course aims at imparting integrated theoretical and practical knowledge on gender and development issues in the South to students, researchers, teachers and development practitioners in different kinds of agencies in Sweden.

Professor Vladimir Cvetkovic is also working on an India related research project. In November 2007, he was given SEK 1.2 million as a three-years grant (2008-10) from Sida’s Developing Country Research Council (U-landsforskningsrådet), for a project titled ”Assessing groundwater vulnerability and risks from on-site sanitation – General method development and case study”. More information about the Sida grants 2007.
Prof. Cvetkovic has been involved in collaboration with the Centre for Water Resources Development and Management(CWRDM) in Kozhikode, one among the R&D institutes of the Kerala State Council for Science, Technology and Environment (KSCTE). In 2005, Dr. P.S. Harikumar from the Chemical Sciences division of CWRDM visited Sweden, and was a visiting scientist working at KTH with Prof. Cvetcovic.
The KTH-International Groundwater Arsenic Research Group (GARG) is regularly engaged in International conferences, symposia and workshops, see a list on http://www.lwr.kth.se/Personal/personer/bhattacharya_prosun//Garg/conferences.htm
The 2nd KTH-Dhaka University International Seminar on Natural Arsenic in Groundwater of South Asia (NAGSA-2005) was held in Dhaka, Bangladesh, in December 2005. The conference was jointly organized by Department of Geology, Dhaka University and GARG.
In February 2006, GARG was involved in organising an International Conference on ”Groundwater for Sustainable Development: Problems, Perspectives and Challenges” (IGC-2006) in collaboration with the School of Environmental Sciences, Jawaharlal Nehru University (JNU), New Delhi, India, and other partners. The conference was held at India International Center in New Delhi. More information.
On Wednesday 16 February 2005 the Swedish Radio Channel 1/Vetenskapsradion broadcasted a programmeon the Arsenic contamination of groundwater in Bangladesh. The programme was called ”Arsenik i grund och botten”, and was based upon interviews with Prosun Bhattacharya, and Professor Marie Vahter from the Division of Metals & Health, Institute of Environmental Medicine; Karolinska Institutet , Stockholm.
Full information on the programme (in Swedish only). Here is also a link to listen to the programme through web radio.
In 2005, Prosun Bhattacharya edited a new book on “Natural Arsenic in Groundwater: Occurrence, Remediation and Management” , together with Jochen Bundschuh (ICE, Costa Rica/Universidad Nacional de Santiago del Estero and UNSE, Argentina); and D. Chandrashekharam (IIT Mumbai, India). The book, published by Taylor & Francis Group, London, was officially released at a function in connection with an India evening at KTH in Stockholm on 16 March 2005. The book comprises 35 scientific contributions, based on the papers presented at the Pre-Congress Workshop (BWo 06) on Natural Arsenic in Groundwaterorganized by the authors during the 32nd International Geologial Congress at Florence, Italy 18–19 August 2004. The publication is an important landmark in its aim of bridging the gap between the researchers’ knowledge about the occurrence of arsenic in groundwater and the underlying mechanisms for its mobilization, remediation as well as a thought provoking challenges for the management of the arsenic problem for the sustainable development of our society.
The book release was officiated by Professor Anders Flodstöm, the President of KTH (on the photo to the left Flodström presents two of the book editors, Bundschuh and Bhattacharya, with flowers as thanks).
It was extended to be an India Evening, attended by among others the new Ambassador of India to Sweden, Deepa Gopalan Wadhwa (photo to the right).
She gave a speech on ”Challenges for safe drinking water in India – Achievement of the Millennium Development Goals”. The ambassador of Bangladesh, Mr. Sabihuddin Ahmed, was also a chief guest at the function.
Prof. Emeritus Gunnar Jacks lectured on ”A walk through the past – Our Experiences with Groundwater Resources in India”, about the 30 years of Indo-Swedish interaction between the department and the Tamil Nadu Agricultural University in Coimbatore, whereas Ramon Wyss, the Vice-President of KTH in charge of International Affairs, talked about ”Prospects of Indo-Swedish collaborations”, focusing on ongoing efforts to increase research cooperation between KTH and Indian institutions.
Staffan Lindberg and Lars Eklund from SASNET were also present at the function, and Prof. Lindberg was given the opportunity to present SASNET’s activities for the audience.
