Research Papers

In this research paper, PATH hopes to identify, adapt and develop water treatment devices and business models for water treatment devices for the ecnomically weaker sections of society.

The sanitation systems studied are spread across the country. The study goes to Pratapnagar in Bihar to evaluate the success of the septic tank to Asalthpur in Uttar Pradesh to study the Ecosan (UDDT) toilet. Other locations in India include Maharashtra, Gujarat, Kerala.

Water use in buildings, accounts for a high percentage of overall water use in cities. With development and growth there has been an increasing demand for water in India. There has been a mismatch between supply and demand because of distribution losses, changing lifestyles etc leading to situations of conflict. Developing water fixtures that use water efficiently is key to reducing this mismatch.

The paper argues that watershed management has to be fluid to take into consideration new realities like change in flow conditions, external realities like unintended impacts and the need to maintain minimum downstream flows for environmental and other purposes.

The following article is a literature survey of water management interventions taken up in Indian fields to improve the water productivity which would in turn reduce the groundwater decline.

This is a status report of Arghyam's sponsored efforts to develop and showcase community managed water and sanitation systems in 17 schools of 7 districts of Karnataka.

The Government of Karnataka through its Suvarna Jala Yojana aims at providing drinking water in 23,683 rural government schools. This was funded to the tune of Rs 7735 lakh. Arghyam conducted a survey of this scheme in 2007 in 7 districts to ascertain the status of the scheme.  The survey found out that out of the 1269 rainwater harvesting structures completed by November 2006 only 140 structures were  functional.

This presentation by ACWADAM deals with climate change and its impacts on long-term replenishment of groundwater. The presentation provides an overview of the current insights and knowledge on climate change impacts and gives an overview of best options for developing and safeguarding groundwater resources.

This series by Thingnam Anjulika Samom deals with the impact of modernisation, development and state policy on the traditional use, control and management of Loktak lake, the largest common property aquatic resource in Manipur. The Loktak Hydropower Project commissioned in 1983 has damaged the ecology of the largest freshwater lake in the northeast, and has altered the culture, agricultural and livelihood patterns of communities residing around Loktak. The series looks at what this common property resource used to be and what it has become.

Loktak, the 300-square-km lake is spread over three districts in the valley – Imphal West, Bisnupur and Thoubal and covers 61% of the total identified wetlands of Manipur. Besides being the source of livelihood for hundreds of people, Loktak also houses the floating national park Keibul Lamjao, the only home in the world to the endangered Sangai deer. It is not only the geographical topography of the lake that has changed in the last few decades. The lake is also beset by increasing pollution, siltation, rapid proliferation of phumdis and the commissioning of the Loktak hydel project in the 1980s Manipur or Imphal River, with the Loktak lake forming the headwaters to provide regulated storage for power generation.

This collaborative research work between National Institute of Cholera and Enteric Diseases (NICED), Kolkata and International Vaccine Institute (IVI), Seoul under the Diseases of the Most Impoverished (DOMI) Program, supported by the Bill and Melinda Gates Foundation aims to give useful information for the prevention and control of typhoid fever and cholera. The aim is to accelerate the introduction of new generation vaccines against cholera, shigellosis, and typhoid fever, through research and capacity-building. 

This paper by National Institute of Cholera and Enteric Diseases (NICED) is based on a prospective, community based study in an impoverished urban site in Kolkata in order to measure the burden of cholera, describe its epidemiology, and search for potential risk factors that could be addressed by public health strategies. The study population was enumerated at the beginning and end of the study period. Surveillance through five field outposts and two referral hospitals for acute, watery, non-bloody diarrhoea was conducted from May 2003 to April 2004.
