The impacts of water infrastructure and climate change on the hydrology of the Upper Ganges river basin – A research report by IWMI

GangaThis study by International Water Management Institute (IWMI) assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin. The Ganges river system originates in the Central Himalayas, and extends into the alluvial Gangetic Plains and drains into the Indian Ocean at the Bay of Bengal. In the upstream mountainous regions, hydropower is the main focus of development with mega and micro projects either under construction or being planned in both Nepal and India.

After the main river channel reaches the plains, it is highly regulated with dams, barrages and associated irrigation canals. All this infrastructure development and abstractions affects the river’s flow regime and reduces flows, which, in turn, impacts downstream water availability, water quality and riverine ecosystems. Furthermore, there are concerns that climate change is likely to exacerbate the water scarcity problem in the Ganges Basin. Therefore, modeling the hydrology of the basin is critical for estimation, planning and management of current and future water resources.Read More

Planning for vulnerability - The hazards and setbacks in coastal legislation – A report by Dakshin Foundation

Planning for vulnerabilityThis report by Dakshin Foundation deals with the hazards and setbacks in coastal legislation. Laws pertaining to specific ecosystems and their use made an appearance over the last three decades and the law pertaining to coastal spaces – the Coastal Regulation Zone (CRZ) Notification, 1991 specifically decides what people can and cannot do on the coastal stretches of the country. This mainly includes where people can live, where establishments can be set up and the nature of activities permissible on the coast.

The basis for each of these regulations is ascribed to certain concerns, principles and concepts and coastal management has seen several shifts and changes in these. The concern around ‘vulnerability’ has seen the emergence of ideas and responses such as introducing ‘setbacks’ for development and establishing ‘hazard lines’. 

The CRZ, 1991 became a subject of intense public debate – beginning as concerns around the massive rehabilitation efforts in the southern Indian states, but thereafter focusing on the inconspicuous reconstructing fragility process of coastal legislation reform that the Ministry of Environment and Forests (MoEF) had initiated in July 2004, just prior to the tsunami.

Impact of the 2004 tsunami on the geology of Car Nicobar Island – A paper in Current Science

Car NicobarThis paper in Current Science deals with the impact of the 2004 tsunami on the geology of Car Nicobar Island. The historic tsunami of 2004 in the northern Indian Ocean severely affected the eastern coastal areas of peninsular India and Andaman-Nicobar Islands. The Andaman-Nicobar Islands experienced intense damage to the coastline, at places reaching several hundred metres deep into the island.

Global equatorial sea-surface temperatures over the last 150,000 years: An update from foraminiferal elemental analysis – A paper in Current Science

This paper in Current Science deals with changes in the global equatorial sea-surface temperatures over the last 150,000 years. Solar insolation changes are amongst various factors that affect sea-surface temperature, which in turn modulate global climate. Out of all the oceanic regions, equatorial region receives the maximum solar insolation and thus is the locale for the warmest waters. However, how the equatorial sea-surface temperature affects global climate, is still not clear.

State of knowledge of coastal and marine biodiversity of Indian Ocean countries – An article from the Public Library of Science

This article in the Public Library of Science deals with the state of knowledge of coastal and marine biodiversity of Indian Ocean countries. The Indian Ocean extends over 30 per cent of the global ocean area and is rimmed by 36 littoral and 11 hinterland nations sustaining about 30 per cent of the world’s population. The landlocked character of the ocean along its northern boundary and the resultant seasonally reversing wind and sea surface circulation patterns are features unique to the Indian Ocean.

Prediction of the Indian summer monsoon rainfall using a state-of-the-art coupled ocean–atmosphere model - An article from Current Science

This article in Current Science by Janakiraman et al deals with the prediction of the Indian summer monsoon rainfall using a state-of-the-art coupled ocean–atmosphere model. A model of the coupled ocean–atmosphere system, the climate forecast system (CFS), from the National Centre for Environmental Prediction (NCEP), USA, has been ported onto the PARAM Padma parallel computing system at the Centre for Development of Advanced Computing (CDAC), Bangalore and retrospective predictions for the summer monsoon (June–September) season of 2009 have been generated, using five initial conditions for the atmosphere and one initial condition for the ocean for May 2009.
