This presentation by Sekhar Raghavan, Director, Rain Centre, Chennai, India highlights the experiences and the challenges faced by Rain Centre in introducing ecological sanitation in the coastal town of Kovalam near Chennai, Tamil Nadu, India along with Coastal and Rural development Trust (CRDT), a small non profit centre based in Kovalam .

The coastal town of Kovalam was selected as a case because of its peculiar situation with its location in a fast developing  peri-urban area in proximity to Chennai city characterised by good groundwater situation, adequate land and housing facilities, but with a glaring and urgent need and demand for toilets.

This paper in the Journal of Earth System Science deals with a study by National Institute of Oceanography (NIO), Goa to investigate the influence of monsoonal rainfall on hydrographic conditions in the Mandovi River of India. The study was undertaken at a location approximately 2 km upstream of the mouth of the estuary.

This paper in Journal of Earth System Science deals with paleochannel and paleohydrology of the Middle Siwalik (Pliocene) fluvial system in Northern India. In recent years, fluvial sedimentologists have carried out numerous studies to estimate quantitative hydrodynamics of ancient fluvial systems, particularly, their morphology and hydrology. The methods for reconstructing the morphology and hydrology employ either several groups of empirical relationships derived from modern fluvial environments or dynamic models of fluvial flow and sediment transports in alluvial reaches.

The report by Paul P Appasamy and Ruth Meinzen Dick deals with urbanization and intersectoral competition for water founded on the view that stereotypical images of “thirsty cities” that equate urban demand with “drinking water” or factories, and rural water supply with irrigation do not adequately portray the water uses in each area.

This paper in Current Science attempts to establish a missing stream link between the Markanda river and the Vedic Saraswati river in the plains of northern Haryana based on geoelectrical resistivity surveys. Resistivity surveys in the Gangetic Plains around Pehowa region in Haryana, have revealed different subsurface geological formations composed of fine, medium and coarse sand with gravel. Resistivity section between the lower part of the Markanda basin and the Saraswati river around Pehowa region indicates the presence of buried sand bodies connecting the two rivers.

Its aim aim was to improve the capacity of target communities to better manage in times of disaster. To set in motion a process that would sustain a short-term project, the Aga Khan Development Network drew on guiding principles developed from its experiences of projects in disaster reconstruction and more comprehensive development programs: high-quality community-based interventions, working on multiple fronts, and fostering linkages with strong institutional partners.

At the core of the project’s disaster management and mitigation strategy was the creation of empowered and highly motivated community-based organizations; their participation was critical in shaping and implementing initiatives that would best serve the needs of the vulnerable, particularly women and children.

 The Committee took evidence of the representatives of the Ministry of New and Renewable Energy (MNRE) in January, 2011.

The initiative on hill wetlands in the Nilgiris Biosphere Reserve is supported through this. The area is located at the junction of the Eastern Ghats and the Western Ghats, or Sahyadris, the two prominent mountain ranges that run almost parallel to the coastlines of Peninsular India and is home to indigenous forest people and is a rare repository of mountain biodiversity.

The Nilgiris is home to unique wetlands that are the source of sustenance of numerous animals and human communities. Wetlands are among the more important reservoirs of biodiversity that nature has painstakingly crafted over millions of years.

This report is a part of Stimson’s Regional Voices: Transnational Challenges project and provides valuable cross-regional and multidisciplinary insights into the complex issues surrounding transboundary water resources and climate change. It examines the environmental dangers and policy dilemmas confronting the sustainable management of shared water resources in a warming world.
